Talking the talk

“

It is imperative to motivate people in a way that they are able to conduct themselves in a manner that will reduce energy while not impacting them in doing their job

Talking the talk is normally said, when used disparagingly, that so and so can talk the talk but cannot walk the walk. In energy, somewhat surprisingly, it’s often the opposite. Many energy managers are highly skilled at doing the actual business of energy reduction within their organisation. However, many are less skilled at communicating especially regarding the need for more budget and further investment in demand side reduction technologies.

The ability to communicate in a way that will enable finance people to understand and want to initiate energy efficiency projects is difficult for many who know all about the parfticular technology but less about finance speak.. Winning people over and speaking their language is not easy for many engineers because it is closer to sales and than technology and equations. Contained within that statement is a huge generalisation, although anecdotally I am told that withholding excellent exceptions it is broadley true. It is also especially important to be able communicate effectively when you wish to enact a behavioural change programme.

Appealing to what motivates people best is a difficult thing. Sometimes it’s competitions between departments, sometimes, social responsibility and often not about saving the company money. Energy consultant John Mulholland talks about obliquity (see page 30) where getting the best results is often not the case of going the shortest or most obvious route.

It is imperative to motivate people in a way that they are able to conduct themselves in a manner that will reduce energy while not impacting them in doing their job. It is rather like the saying ‘give a man a fish and he will eat for a day, teach him to fish and you have feed him for life, although if he doesn’t like sushi you’d have to teach him to cook too, although that’s besides the point. Give a man a seminar and he learns a few things about energy reduction but make him understand how this could benefit him, his colleagues and his job and he will continue to do them from then onwards.

The energy manager of the future will have to be an engineer, a salesman and a psychologist. It’s a tall order but there are signs that the subject is developing in that direction and content reflects this in the multitude of seminars and conferences that exist.

Refocusing energy policy on buildings to save over £12bn per year Industry today set out ambitious recommendations to all political parties for how the UK economy could save billions by placing buildings at the heart of energy policy.

The Sustainable Energy Association’s Manifesto, published on 7 July, uses the Government’s own online calculator to demonstrate how an ambitious programme of insulating buildings, and producing more energy directly from buildings themselves could net savings to the economy averaging £12.1bn per year from now until 2050. This is equivalent to a £189 saving per year, every year, for every UK citizen.

The SEA manifesto calls on all major political parties to adopt a renewed approach to energy policy, focusing on: • An Energy in Buildings Strategy • A major focus on the use of smart technology to treat buildings as an integral part of the energy system • A new approach to home heating, recognising the potential of the

heating installer • A major infrastructurebased energy refurbishment of the UK’s buildings Dave Sowden, chief executive said: “We have known for a long time that energy measures in buildings are cheaper in the long-run.

Now the Government’s own tools and assumptions yield the same answer. There is a compelling case here to create a much stronger focus in energy policies on buildings.

This will reduce waste, enhance energy security, reduce imported fossil fuels, lower people’s fuel bills and make a huge contribution to the UK economy. It is win/win all round.

“Technology manufacturers, installers, merchants, financiers and engineers; all have mobilised to identify how we can deliver an ambitious and affordable energy future for the UK. This Manifesto is our appeal to all the main political parties to come with us and build new consensus on energy policy, with buildings at its heart.”

Can supply contract terms be negotiated?

By Ben Dhesi, cofounder and head of energy management, Pulse Business Energy Ltd When settling a supply contract for a London law firm this month we were sent a list of red line amendment requests by them to alter their supply terms and conditions.

The customer was considered an SME account so any chance of the supplier entertaining the changes were virtually zero. I&C customers can effect some of their terms and conditions but in the SME market the suppliers’ general T&Cs are very much take it or leave it.

The lawyers were surprised by how weighted the T&Cs were in the suppliers’ favour to the point they could be challenged under The Unfair Contract Terms Act or the Sales of Goods Act (however, businesses have very limited rights under these Acts).

One reason that suppliers won’t review SME T&Cs is not that they are unreasonable per se but it would require getting their board and their lawyers to sanction the changes, which would be a costly exercise rendering the contract (and perhaps their SME model) commercially untenable.

So if the suppliers and any SME customers have an issue during their contractual relationship, the SME customer can well find themselves checked in every conceivable scenario.

In the case of the SME law firm, we explained that the supplier’s terms and conditions “are not for turning” and pointed them to their existing terms and conditions, which they liked even less, to demonstrate that every supply contract would distribute the

balance of power in the suppliers’ favour.

However, the reality is that suppliers often don’t invoke their T&Cs at every opportunity and the need to keep good relationships with the SME market keeps things in check as SMEs and their brokers have the power to vote with their feet and leave suppliers en masse; which I have seen happen, particularly in relation to suppliers that invoke their Take of Pay terms.

Given the value of the contract, I&C customers have far more commercial control when it comes to negotiating T&Cs even though the suppliers starting position won’t be ideal. Areas where it pays dividends for I&C customers to negotiate are: Q shape or baseload optimisation; Q tariff structures; Q take or pay terms; Q wholesale trading terms; Q non commodity charging terms; Q termination (addition and removal of supplies).

Often you can overlook the fine print and 99% of the time it won’t matter. However, that 1% of the time can be costly (EMR terms needs particular consideration) and might need a huge amount of retrospective time and resource to resolve the situation. I&C contracts “should be like clothes and fit the people they serve” and you should also consider how the terms impact wider policies like demand management and ESOS. Want to know more?

NEWS & COMMENT

Solar policy U-turn to face judicial review Energy Secretary Ed Davey has been accused of slamming the breaks on Britain’s fledging solar energy business as the industry today launches a Judicial Review against the Government.

Four of Britain’s biggest solar businesses say Davey’s sudden and unilateral withdrawal of support for solar is unlawful. They warn it could land the government with an embarrassing U turn in the run up to the General Election.

The unlawful policy change is certain to heap embarrassment on Deputy Prime Minister Nick Clegg who has repeatedly pledged to persuade renewable energy investors that the UK is a safe and stable place to invest.

This will be the third time legal action has been brought against DECC’s unlawful solar

“DECC is acting unlawfully by retrospectively pulling the plug on a scheme to provide certainty policies in as many years.

Just three weeks ago, Davey’s department was landed with a compensation bill of up to £132m, following its decision to make retrospective cuts to the Feed-in Tariff (FiT) scheme. The FiT supports small-scale solar, primarily on people’s homes. Sudden cuts

in 2012, leaving solar installers insufficient time to react, were ruled unlawful by the High Court. Within days of the court ruling, Greg Barker the minister in charge resigned.

In an embarrassing development for Davey, the latest Judicial Review accuses DECC of making the same mistake again. This time the target is the Renewables Obligation, the scheme that supports larger scale solar on the roofs of industrial buildings or mounted on the ground.

DECC has announced plans to end the Renewables Obligation (RO) in nine months’ time, two years ahead of schedule. DECC is acting unlawfully by deciding to retrospectively pull the plug on a scheme designed to provide the industry with confidence and certainty, according to the

Judicial Review claimants.

DECC’s actions could cost large numbers of jobs and will rob the solar industry of hundreds of millions of business, say claimants TGC Renewables, Solarcentury, Orta Solar Farms and Lark Energy, who have appointed Prospect Law to advise on the Judicial Review.

The solar firms are part of an 800MW supply chain worth over £800m, with enough projects in progress to provide power to over 200,000 homes.

They accuse Davey of conducting a sham consultation and basing his plans on cost figures for solar that are way out of date and have argued that it will be Britain’s tax payers who are presented with paying the compensation bill running into hundreds of millions of pounds.

Highest efficiency thin film PV cell on record First Solar has announced it has set a world record for cadmium-telluride (CdTe) photovoltaic (PV) research cell conversion efficiency, achieving 21.0% efficiency certified at the Newport Corporation’s Technology and Applications Center (TAC) PV Lab. The recordsetting cell was constructed at the company’s Perrysburg, Ohio manufacturing factory and Research & Development Center, using processes and materials designed for commercialscale manufacturing.

The record has been documented in the US Department of Energy’s National Renewable Energy Laboratory (NREL) “Best Research Cell Efficiencies” reference chart.

This certified result bests the previous CdTe record of

20.4% conversion efficiency, which was set by First Solar in February of 2014, and represents the seventh substantial update to CdTe record efficiency since 2011.

The achievement also places First Solar’s CdTe research cell efficiency above copper indium gallium diselenide based solar cells (CIGS)

6 August/September 2014 | water energy & environment

at 20.9%, and well above multicrystalline silicon (mSi), which peaked at 20.4% in 2004.

“We have just begun to reveal the true unrealised potential of CdTe PV,” said Raffi Garabedian, First Solar’s chief technology officer.

“Not only have we have now demonstrated the highest single junction thin film

cell on record, but just as important, our record cells are based on the same scalable manufacturing processes and commodity materials that we have proven through years of volume production.”

Garabedian noted that while competing technologies are using increasingly costly materials and cell processes in order to deliver moderate performance gains, First Solar is establishing a rapid path to industry-leading energy densities, while simultaneously improving manufacturing metrics.

At an analyst briefing last March, First Solar presented a technology roadmap anticipating a 22% research cell efficiency milestone in 2015. Today’s announcement indicates First Solar is steadily tracking to achieve that goal ahead of schedule.

Get ready for the ERP Directive “ErP will effectively, over time, eliminate all inefficient products up to 400kW from the market

replacing the affected module.

Manufacturers therefore need to focus on not only ensuring their products are ErP ready, but also providing support and information to make the transition as easy as possible for their customers – the installers, contractors and specifiers. For the installer, the ErP directive means more paper work will need to be completed during the commissioning phase to provide a package label for the combined heating products installed.

The ErP is almost upon us and the commercial heating industry needs to act now to ensure it is ready for the next phase. Baxi Commercial has produced an ErP infographic to help the industry understand what the change will mean, which is available for download from www.baxicommercial.co.uk.

With the Energy Related Product Directive – or ErP – due to be implemented in just over a year’s time, there is a busy time ahead for the commercial and residential heating industry.

Installers, specifiers, contractors and manufacturers alike need to be ready for the change.

Coming into force in September 2015, the directive will mean boilers and renewable heating equipment will be given an efficiency rating. The directive comprises Ecodesign and Energy Labelling Regulations for Lot 1 (space heaters and combi space heaters) and Lot 2 (water heaters). This will mean two things.

1. Ecodesign – any product that does not meet certain efficiency requirements will not get a CE mark, and will, therefore, not be

legally available for sale.

2. Energy Labelling – will mean that each space and water heater will come with an efficiency rating and label, from G to A+++.

This will have a significant impact on the commercial market as it covers fossil fuel boilers and water heaters output up to 400kW. ErP will effectively, over time, eliminate all inefficient products up to 400kW from the market.

The major impact on the market from ErP will be from September 2018 onwards, when the nitrogen oxide (NOx) emissions are reduced. The effect this will have on the industry is huge. If we calculate gross seasonal efficiency using the Part L Building Regulations formulae and apply them to Lot 1, the equivalent seasonal

Water footprint ISO standard

New partnership to track UK’s journey towards improved energy efficiency

ISO has published a standard for measuring your water footprint. ISO 14046, Environmental management – Water footprint – Principles, requirements and guidelines, will allow organisations the means to measure their ‘water footprint’, or their potential environmental impact of water use and pollution. The standard is based on a life-cycle assessment and can assist in: • Assessing the potential environmental impacts related to water, • identifying ways to reduce those impacts, • facilitating water efficiency and optimisation of water management at product, process and organisational levels and • providing scientifically consistent and reliable information for reporting water footprint results.

The UK Green Investment Bank (GIB) is partnering with EEVS Insight and Bloomberg New Energy Finance (BNEF) to help expand the quarterly Energy Efficiency Trends publications. GIB support will help to expand the contributor base, strengthen the research, and promote the publication’s insights to a wider audience.

Energy Efficiency Trends is operated by EEVS with support from BNEF. A rolling ‘state of the market’ publication, the results are based on a quarterly survey of both energy efficiency customers and technology and service providers. Reports are published quarterly with the eighth edition due out in September 2014.

Bill Rogers, head of strategy and co-managing director of Energy Efficiency at GIB, said: “Non-domestic energy efficiency has a critical role to play in improving the UK’s competitiveness and building a greener, stronger economy. This is an area of huge opportunity for the UK’s private and public sectors and we hope to see a quickening of the pace of progress in the months and year ahead.

“Any new, growing market needs a definitive source of data and analysis. EEVS / BNEF’s Energy Efficiency Trends already fulfils that role and, as the UK’s most active investor in nondomestic energy efficiency,

we hope our support and insight will help to take it from strength to strength.

Ian Jeffries, head of information services at EEVS, said: “With Green Investment Bank support we will be ramping up and extending the reach of this important market research – great news for anyone interested in UK energy efficiency.

Tom Rowlands Rees, head of energy efficiency at Bloomberg New Energy Finance, said: “Results from the last Energy Efficiency Trends report show an increase in the share of projects using combination and third party financing. It is therefore fitting that we bring the GIB on board to help us navigate investment trends through their on-the-ground experience in the sector.

NEWS & COMMENT

Short term thinking is damaging A new CBI poll shows over half of business leaders think energy security is worse than five years ago.

Short-term thinking is distorting the debate on our energy future, risking investment and opportunity.

And in a new CBI poll of over 550 business leaders and 2,300 households, businesses rate security of supply as a crucial energy objective for the UK, with 73% citing it as very important.

Over half of businesses (57%) also think the UK’s energy security is worse than it was five years ago, reflecting that capacity margins are

likely to hit a low next winter.

Businesses and households are concerned about keeping energy bills affordable (96% of businesses and 94% of households rating this as important or very important).

And both groups support the UK’s aim to tackle climate change (70% of businesses and 76% of households rating this as important or very important).

In a speech to the CBI Energy Conference, Katja Hall will say: “Long-term certainty is needed but just as policies start to click into place, the political climate heats up again. It feels like a game of snakes and ladders.

“One careless comment or populist proposal – whether we’re talking about cutting support for onshore wind farms or freezing energy prices – can make businesses feel like they’re right back at square one.

“For investors, this is a real worry. And when that investment can go anywhere in the world, it should be a real worry for politicians too.”

Reform of EU ETS is needed say manufacturers Britain’s manufactures are calling for significant reform of the EU Emissions Trading System (EU ETS) warning that, left unchecked, in its current form it could drive crucial investment in energy intensive industries (EIIs) out of Europe.

The call was made by EEF, the manufacturers’ organisation which believes the reform must also be accompanied by a wider review of EU climate change policy to ensure it is fit for purpose to achieve the twin goals of reducing emissions, whilst keeping key industries competitive.

Commenting, EEF head of climate & environment policy, Gareth Stace said: “Reducing our carbon emissions through to 2030 is going to be an enormous challenge with the targets currently on the table representing a tripling of effort from 2020 onwards.

We cannot hit those targets without support for energy intensive industries and reforms must ensure we retain these in Europe.

“If we leave the EU ETS essentially as it is today

with only minor reforms then we will only serve to push these vital industries through the exit door to other parts of the world.

“The current climate change landscape is also markedly different to a decade ago when EU ETS was first introduced and policy needs to reflect this.

Between now and 2020 we have the opportunity to take stock and reform the wider policy framework. This will ensure it is fit for purpose and keep our fundamental industries competitive while, at the same time, helping them decarbonise and introduce new technologies.”

The European Council will meet in October to reach agreement on an energy and climate change framework to guide the EU through to 2030. This will examine a new emissions reduction target and the possibility of renewed commitments for energy efficiency and renewable energy.

At the centre of this framework sits the EU ETS which is tasked with reducing emissions from the power and industrial sectors by placing

“If we leave the EU ETS essentially as it is today we will push industries through the exit door to other parts of the world a price on carbon. Reform proposals will see increasingly tough targets through the 2020s and mechanisms to increase the price of carbon.

However, EEF is warning that, while this will deliver investment in many sectors, including renewable energy, without additional support and protection measures it will do little more than reduce EU production in some sectors and drive investment and emissions abroad.

EU energy policy will cost us dear Eurosceptic organisation Business for Britain claims in a research paper that EU energy regulations will cost the UK economy between £86.6 billion and £93.2 billion (net), putting 1.5 million jobs are at risk thanks to high energy prices. The figures are drawn from an investigation of official government impact assessments and analysis of energy intensive industries particularly affected by high energy prices.

Its position papers are a part of series of research designed to outline sensible EU reforms that British businesses want from the forthcoming renegotiation. The report identifies the impact of recent EU energy laws and suggests a more cost effective way of securing a transition to a greener economy. Member states should be given the power to determine the appropriate energy mix to enable them to meet EU emissions targets, without subjecting firms to the burden of excessive regulations.

The research suggests: Energy prices in the European Union are among the highest in the developed world. Medium sized industrial consumers in the EU pay around 20% more for electricity than companies in China, about 65% more than companies in India and more than twice as much as companies based in the US and Russia.

EU policies currently account for up to 9% of the cost of energy for Energy Intensive Industries. By 2030 this could rise to just under 16%.

Were the UK to opt out of the Renewables Target alone, energy bills for Energy Intensive Industries could fall by up to 7%.

ISO 50001 is needed and worth the ROI In the 2012 edition of Energy Efficient Solutions, the question was asked: “Is the new energy management standard actually needed?” In that article, the case for the fledgling ISO 50001 was made using examples from Costa and Royal Mint. So two years later, where are we now and what has changed, asks NQA environment & energy sector manager Martin Hockaday

S

ince ISO 50001 was published in 2011, it has gone from being the newkid-on-the-block of ISO management standards to an essential management tool with the potential to deliver return on investment and legal compliance.

According to the annual ISO Survey, certification to ISO 50001 grew by 332% between 2011 and 2012, with absolute growth achieving more than 1500 accredited certifications. Significant new growth is expected to be reported in the 2013 ISO Survey due in autumn 2014.

In its first year, the rate of adoption of ISO 50001 exceeded that of ISO 14001 and is rivalling the uptake of ISO 9001 in the mid 1990s.

If this continues, ISO 50001 will be one of the most widely adopted management systems standards within a few years.

Fuelling growth The cost of energy for heat, light and power is itself a major driver of energy management systems (EnMS) implementation.

The price of gas and power is unpredictable due to geopolitical influences on the markets, so it is ever more critical to manage consumption effectively and efficiently – whether that be through technology, behavioural change or management systems.

In addition to cost drivers, the government introduced the Energy Act and now the Energy Savings Opportunity

10

Scheme (ESOS) to meet the requirements of the European Union; more specifically Article 8 of the European Union Energy Efficiency Directive. This is an EU initiative to accelerate the drive towards greater energy efficiency and reduced carbon emissions from businesses.

The Department of Energy & Climate Change has issued a summary guide to ESOS in June 2014.

Energy management in the private sector is a major factor in helping the government to achieve its carbon emissions reduction targets of 34% by 2020 and 80% by 2050, compared with 1990 levels.

ESOS is the latest in a range of initiatives designed to reduce energy usage. The conservative estimate is that audits will lead to an average 0.7% energy saving per enterprise and ESOS is expected to provide a net positive benefit to the UK of between £800m and £3bn.

For the 7,300 organisations that the UK government estimates will now have to carry out mandatory energy audits, ESOS could be an expensive and time consuming initiative. One of the best solutions is to implement an energy management system certified to ISO 50001; this not only assists with legal compliance but it can deliver return on investment and continual improvement.

a significant investment in time, budget and resource.

Naturally, payback is a key consideration and fairly straightforward with the implementation of a technical solution, such as LED lighting or solar pv installation. But with a management systems approach the payback can be harder to attribute, particularly where cultural change is concerned.

Coffee chain Costa implemented ISO 50001, which helped it save 16% of its overall energy consumption (32% reduction per tonne of coffee roasted).

This allowed it to increase production without the need to invest in a new roasting facility. It has also used the certification to influence cultural change and reinforce the message of energy efficiency.

Ben Brakes, environment manager at the Whitbread Group which own Costa, confirms “It gives you something over and above the usual ‘switch it off ’ campaigns and allowed us to really engage people with simple housekeeping issues like switching off lights and closing windows.”

By Serge Mazodila, lead trader of LG Energy Group With a complacent mindset and a “steady as she goes” summer 2014 trading attitude, European energy prices have lingered near all-time lows since April due to the tamed demand levels and warm temperatures, which have cast a Bearish blanket over prices during the season.

A sideways glance at summer The 2014 summer year-on-year increase of UK gas consumption, up almost 20%, has paved the way going into the upcoming trading winter of 2014/15, setting a precursor for future energy demand expectations, having seen an increase in natural gas usage amidst the comfortable warm temperatures.

A battle to the upside, which commenced back in July, saw energy prices (gas and electricity) rebound from record lows thanks to a technical-led buying spree that was later hijacked by a plethora of geopolitical risks relating to Eastern-Europe and the Middle-East. Already, prices have rallied quite aggressively on the back of perceived supply disruption risk, via Ukraine, leaving potential for further upside shocks to come from the cooler weather and increased demand, once winter descends.

A changing balance between risk and reward The biggest market risk ahead now lies in the form of highly complacent summer traders who have benefited from the unusually warm winter of 2012/13.

With prices at record lows as we move into a winter trading period, on a risk/reward basis, against the impending upside risk, the associated potential downside moves in the last month of summer no longer

seems appetising. As weather patterns alter, temperatures cool and demand picks up to reflect the upcoming season, prices now look more favourable to the upside moves, and the likelihood of new winter record lows seems increasingly slim.

Ahead is “A Song of Ice and Fire” As we head into the winter trading period of 2014/15 with mounting ambiguity relating to the Middle-East (Iraqi crisis) and Eastern Europe (Ukraine vs Russia), a “Bullish” outlook for the UK’s energy market after a

very comfortable summer trading season only reflects the imminent upside risk still present in the form of global market uncertainty.

LG Energy’s Bullish outlook aims to raise questions as we conclude the warm trading period of summer 2014, with a bold acknowledgement, which reiterates our previous statement that prices may brutally, and swiftly, move to the upside in the winter. As a result, the need for a highly sophisticated approach to quantitatively measure end-users’ market exposure risk and the cost of the widespread complacency should be paramount, ahead of what may be another slow start to the winter of 2014.

Revenue and settlement gaps Engage launches new cost module to tackle billing vs settlement challenges for energy suppliers

E

ngage Consulting, a UK specialist utilities and smart energy consultancy, has added a new cost module to its Revenue and Margin Assurance (RAMA) Solution, which will enable energy suppliers to calculate gross margin for each of their meters.

Gaps between billed revenue and settlement costs are a common problem for suppliers. They can result in millions of pounds of lost revenue through over settlement and under billing and damage customer relationships through overbilling. Such gaps are difficult to identify and time consuming to resolve, as the processes involved are highly complex.

The causes of imbalance gaps Any number of factors can

contribute to imbalance gaps including: • inaccurate meter readings –– resulting in use of incorrect or estimated readings • incorrect information held in billing systems – resulting in billing inaccuracies • incorrect information held in settlement and registration systems – resulting in inaccurate settlement volumes RAMA automatically tracks, monitors and analyses suppliers’ billing and settlement data on an on-going basis, identifying the sources of energy volume and cost discrepancies across their electricity and gas and customer portfolios. Any volume gaps and margin issues are flagged up in time

for issues to be resolved before the billing and settlement deadlines expire and suppliers gain complete visibility of which meters are causing problems. The system provides vital business information on their efforts to manage the imbalance gap that can help suppliers increase their profitability.

Richard Cullen, practice director, Engage Consulting said, “Getting the balance right between settlement and billing can be tricky and costly for suppliers. RAMA has been designed by energy sector technical experts with a deep understanding of customer billing and settlement processes, and data analysts with many years’ experience working with energy suppliers on these issues. We believe RAMA can benefit all energy companies, whether they are a niche supplier or one

operating across a number of customer segments, deliver tangible financial and customer benefits and mitigate regulatory risks.

With the countdown to the smart meter rollout in the UK just over a year away, now is the time for suppliers to get on top of their billing and settlement processes and put automated systems in place that will enable them to maximise all the opportunities in the smart world.” we&e

Wholesale prices too low for investment yet high for consumers The current European wholesale prices are too low to attract new investments in generation without subsidies according to Finnish company Fortum Energy’s Energy Review.

The report focuses on an European cost efficient climate and energy policy approach, its key findings suggest: • Share of electricity in the final energy consumption will continue to grow • Rapid growth in renewable power generation is driven by a variety of support mechanisms and declining technology costs.

The EU 2020 targets are likely to be met, but at a high cost • The current European wholesale prices are too low to attract new investments in generation without subsidies.

Adequacy of generation capacity is a concern.

• European end-user prices have increased due to higher taxes, levies and networks costs • Renewable energy technologies are becoming commercially viable - transition towards a renewablesbased energy system is possible with less subsidies if supported by a carbon price and market • The EU 2030 energy and climate policy should be based on a leading emission reduction target with an enforced Emissions Trading System (ETS) Fortum’s president and ceo Tapio Kuula at the Review launch event: “As European competitiveness is a key concern, a costefficient climate policy to minimise the price tag of decarbonisation for society is of utmost importance. Decisions on the 2030 climate targets and a structural reform of the ETS are urgently needed to boost the decarbonisation of society. In parallel, global efforts for pricing of carbon should be accelerated.”

The results were surprisingly consistent. At a certain level of seniority and above, the requirements were for a single page report that answered the following questions: How much have I bought this financial year?

How much have I yet to buy?

What’s the delivered, retail cost of the above?

If I bought now, with the current market conditions, where would I be against budget?

Project numbers soared by 40% Almost £300m invested in booming independent renewables sector last year

A

lmost £300m was invested in commercial-scale independent renewable energy projects by businesses, communities, farmers and landowners last year, new figures reveal.

The statistics compiled by SmartestEnergy for this year’s Energy Entrepreneurs Report show 843 new projects, with an average cost of £353,000 each, came on supply.

The 2,930 non-Big Six projects of over 50kW capacity now in operation across the country can generate almost 20TWh of electricity a year, close to meeting the entire power needs of the UK’s public sector.

The 40.4% increase in the number of new projects and 31.9% increase in capacity compared to last year’s Energy Entrepreneurs Report highlights the scale of appetite for investing in renewable energy currently.

With a combined capacity of just over 6.2GW, independent sites - ranging from community wind turbines on remote Scottish islands to onsite generation facilities at major manufacturing plants –are together equivalent to several large traditional power stations.

The Energy Entrepreneurs Report figures also show:

Iain Robertson, SmartestEnergy’s Head of Generation, said the second annual Energy Entrepreneurs Report highlighted the significant economic contribution the independent generation sector was now making as well as helping meet the country’s energy needs and climate change ambitions.

“This year’s report really underlines just how important the independent renewables sector is becoming and the scale of investment being made by energy entrepreneurs.

“More than £1m was invested every working day in 2013 and the 843 new projects commissioned are now having a direct impact on the businesses, communities, landowners and developers behind them.

“Faced with steep rises in energy costs and concerns over security of supply, investing in renewable energy projects is a highly cost-effective way to save money and develop a new income stream.”

Robertson said the introduction of financial subsidy schemes such as the Feed-in Tariff, new funding options and reductions in some technology costs had been a significant factor in the growth seen in the sector in the past two years.

Businesses brace for change as EMR goes live As the UK moves into the next phase of the Electricity Market Reform (EMR), Darren Lennon, head of strategic sales at npower, urges businesses to respond to the changing policy landscape to ensure they remain competitive The EMR is one of the biggest shake-ups in our industry since its privatisation over a decade ago, and we’re now preparing for change as policies become law.

With the regime having gone live on 1 August, we’ve been hard at work to ensure that businesses understand exactly how this will affect them.

The EMR has been designed to attract £100bn worth of investment, which is needed to replace the UK’s ageing energy infrastructure with a low-carbon energy mix to meet EU carbon reduction targets.

The first step in the implementation phase kicked off at the beginning of August, with the application process for both the capacity auction and first Contracts for Difference (CfD) allocation round beginning, and the Low Carbon Contracts Company (LCCCs) becoming operational. The LCCC, the government-owned CfD counterparty body, is key to managing the new CfDs, the impacts of which will be felt more immediately.

Briefly, CfDs are being introduced to provide long-term price certainty for the generation of low carbon electricity in order to increase investment in these low carbon technologies. CfD generators will continue to sell their renewable energy and other low carbon electricity into the market, but contracts will provide a top-up from the market reference price to a pre-agreed strike price, reducing the risk of

price uncertainty. Allocation of the first round of CfDs begins this autumn, with the outcome due to be announced in late December 2014. For businesses, there is a cost associated with this change in policy.

While it is difficult to quantify the exact pricing impact, we anticipate that CfD costs will begin to appear on bills from April 2015 at approximately £0.5/MWh, and this will increase on a quarterly basis to approximately £8/MWh by 2020. Volatility will be managed through a quarterly fixed rate, in order to provide some certainty for budgeting.

The time has come to stop debating the uncertainties of impending policy and to start acting on it by planning ahead.

At npower, we’re urging energy managers to talk to their supplier for advice on making the most out of existing assets, as well as ensuring clearer budget certainty in the changing energy landscape.

ELECTRICITY DEMAND REDUCTION

Helping to unlock energy savings?

Ian Byrne, Deputy Chief Executive, National Energy Foundation look at EDR and asks whether it will lead to genunienly new projects being developed

T

he Government has recently launched an Electricity Demand Reduction (EDR) Pilot Scheme. This is a new approach to saving energy in the UK, and is designed to combine more traditional energy efficiency measures with reductions in demand at peak periods – typically 4.00pm to 8.00pm in winter months.

What is Electricity Demand Reduction?

The Government’s Department for Energy and Climate Change (DECC) defines Electricity Demand Reduction (EDR) as meaning electricity savings that are achieved through the installation of more efficient electrical equipment. To qualify for the pilot, new equipment must reduce electricity demand at all times of operation, not just in peak periods. DECC differentiates EDR from the more common Demand Side Response (DSR), where operation of equipment is reduced or the time of operation is changed.

Savings are calculated by comparing energy use before and after a project.

Although this pilot will clearly help the UK meet its carbon reduction targets (and should also reduce energy bills for participants), the main driver is to reduce electricity demand at peak times. The pilot is part of a much wider range of policies designed to introduce a Capacity Market, with the aim of maintaining reliable and affordable electricity supplies, even at times of very

high electricity demand. At present, the Capacity Market encompasses power stations, electricity storage providers and large energy user who can switch demand to other times (demand side response).

EDR supplements the Capacity Market by seeking to reduce the level of demand placed on the electricity network. The EDR Pilot is designed to test whether electricity demand reduction has a role to play in the Capacity Market and to help DECC (and participants) understand suitable delivery mechanisms for Electricity Demand Reduction. Although the EDR approach has been used elsewhere (including France, New England and on the US West Coast), it is a relatively unusual approach to encouraging savings, and there is likely to be much to learn.

The Capacity Market uses an auction to match capacity with prospective suppliers, and the Government has decided to test a similar approach with EDR. The first auction in the pilot will be held on 12 January 2015, with £10 million being earmarked for supporting programmes and a second auction likely to be held in 2016. Participants will have to deliver demand reductions over the 2012-16 winter peak period of at least 100kW, although it is possible to aggregate reductions from a number of smaller sites to meet this total.

How can people participate?

DECC has set out a detailed participant guide on its website, but as this is the first time the approach has

DECC does not want to support only those projects that might have gone ahead anyway, can it lead to genuinely new projects taking shape

been used in the UK there is still some uncertainty about how it will work in practice. More details follow in the article overleaf ).

Once you are accepted onto the pilot, the real work begins. Participants must install the agreed measures and complete an Operational Verification in line with their M&V Plan before the start of the Winter Peak period (ie. 15 October 2015). There will be limited flexibility on the EDR measures actually installed, but they must be of the technology types specified in the original application.

Following Operational Verification, participants must collect and report on data for the operation of their EDR measures during the 2015/2016 winter peak.

Evidence must be provided to DECC by 15 April 2016 and participants will be paid 80% of the full payment for delivering and reporting full committed capacity savings.

(Lower savings will lead to a financial penalty of 2% for each 1% below target.) Finally there will be Final Report (including 12 months data and evaluation evidence) needing

to be submitted by 1 December 2016; DECC may also require some of those taking part to take part in questionnaires, interviews and focus groups.

Is it worth it?

This is the hardest question of all to answer. There is no explicit reference to additionality, so the pilot may be used to improve the returns on an otherwise marginal energy efficiency project.

Clearly DECC does not want to support only those projects that might have gone ahead anyway, but one part of the pilot has to be to see whether it can lead to genuinely new projects taking shape. And although there is a significant level of complexity in the whole process, including the auctions, the rules are set out with reasonable clarity.

Without having seen any calculations, at this stage it is very hard to tell which measures are likely to be most appropriate. DECC will permit a wide range, including lighting, controls, variable speed drives and refrigeration, but experience from other “technologyneutral” programmes is that a small number of technologies fit the rules best and gather the lion’s share of funding.

We also suspect that, given the range of alternative incentives available to social housing providers, it is not likely to appeal to housing associations in their potential role of aggregators. However, we would welcome talking to associations to see if between us we can come up with possible projects. nef.org.uk

ELECTRICITY DEMAND REDUCTION

£20m ‘free money’ scheme to incentivise Ian Jeffries of energy analysis firm EEVS provides valuable insight to the government’s new Electricity Demand Reduction pilot. Find out what it is, how it works, and how you can get your hands on the money

Y

es, you did read that correctly – DECC’s new Electricity Demand Reduction (EDR) pilot offers organisations cash incentives in return for delivering electricity savings – ie, you get paid to reduce your operational cost base. On this basis alone, it is worth reviewing how it works and if it is something your organisation could benefit from.

The first thing to note is that the scheme is not to be confused with electricity demand side response, which is about turning equipment off during moments of significant stress on the Grid and so switching time of use. Electricity Demand Reduction, by contrast is about incentivising longterm electricity savings.

The underlying theory is that long-term electricity savings (“negawatts” if you will) could, in principle, compete with new electricity generation, demand side response, and electricity storage to meet the UK’s overall electricity capacity needs. By using a governmentdevised “capacity market” auction, these approaches would compete and the most cost effective bids, (for either megawatt generation or negawatt savings) would win government funding.

Reducing capacity through efficiency The rationale is an enlightened one. Rather than simply building more and more generating capacity – almost certainly requiring imported gas and billions of pounds

of investment – let’s turn the capacity problem on its head and use a proportion of this money to incentivise public and private sector users to make a material step change in their own efficiency. If successful it would have the effect of reducing overall capacity needs and potentially reducing the need for additional capacity in the first place.

In terms of the specific policy, it could appear somewhat counterintuitive (“so you want to pay me to save electricity and become more efficient, right?”). Yet the logic is compelling; there is certainly scope for UK plc to become significantly more efficient and doing so is only going to be better for UK competitiveness, better for the environment, better for the UK’s security of supply, and a valuable means for meeting our long-term carbon reduction targets.

Sounds pretty compelling.

And EDR could also be taken as an acknowledgment by

“

The bottom line for many organisations is that the steep upfront costs and long paybacks are a material barrier

DECC that energy efficiency is more than just “a good thing”; a strategic-level investment in the long-term sustainability of UK plc.

Yet the financial incentive associated with EDR is also an acknowledgement that the UK market has not delivered energy efficiency improvements as quickly or effectively as we would like. The bottom line for many organisations is that the steep upfront costs and long paybacks are a material barrier. Energy saving investments need to compete against the broad range of corporate investment choices and, too often, energy efficiency loses out. When it does win out, the successful projects are arguably less expansive or ambitious than they could potentially be.

Our own energy efficiency trends research regularly finds that a financial payback of three years or less is required to get an energy saving project over the line, that a

Eligibility checklist To receive funding, projects will need to meet the following requirements: t Sites must be in Great Britain and be connected to the Grid . t Savings must come from retrofit projects – ie, installation of more efficient electrical equipment, not from fuel switching or turning kit off. t The project must deliver permanent electricity reductions during peak demand (defined as between 4pm and 8pm on the 83 business days from 1 November 2015 to 29 February 2016 for pilot purposes). Only electricity (kW) savings achieved within this timeframe are eligible t The project must deliver an average of at least 100kW of capacity savings across this winter. period (ie, at least 33.2MWh of energy savings). It should be installed and delivering these savings by 15 October 2015. t The project must not be collecting any other government incentives. t Project payback must not be less than two years (if so, the project really should be happening any way and without government support). t Finally, an energy saving measure with a shelf life of two years or less is not eligible, as EDR aims to support long-term electricity savings.

three- to five-year payback is becoming marginal, and that anything with a payback of five years or more is likely to receive short shrift. You may have a great electricitysaving project, but if it doesn’t meet these commercial imperatives it’s very unlikely to become a reality.

This is where the EDR scheme could come in. Say you’ve completed the business case on your ideal scheme and the payback comes in at seven years – and your FD’s response was not in the positive – all is not lost. In this example there is the opportunity to bid for the monies that would be required to achieve financial acceptability. Say your FD is happy with four or five years, you could bid in this marginal capital requirement.

If successful – on the basis that your project delivers enough electricity saving bang for the DECC buck – you get the funding and the project can go ahead. You get to make a step-change to organisational efficiency that would otherwise not have happened.

And you get paid for it.

This is the theory, and DECC is now keen to test it out in the wild. There’s £20m on offer and two pilot auctions are planned: the first in January 2015 to allocate £10m of funding; a further £10m auction is due to follow later on.

What is the process for getting hold of this money?

Well, as you might expect with a government scheme of this kind, there’s plenty of bedtime reading and a few hoops to jump through, but below is a quick guide to the application process: Stage 1: Expressions of Interest – If you have an electricity-saving project or programme in mind – or even better, on paper – you have until 30 September 2014 to submit an Expression of Interest, which is a simple 10-15 minute exercise to provide some basic background information.

Stage 2: Full Application – If the project meets the eligibility test (see checklist left) you are in a good position to submit a Full Application to DECC along with an accompanying Measurement & Verification Plan (see M&V summary over page). The tight deadline for this is 31 October 2014. Applicants should know by 1 December 2014 if they have been accepted to take part in the auction.

Stage 3: Bid in the Auction – With a successful application you can then bid in a price for your project. Remember, it’s a competitive auction and what you bid is entirely up to you. You will need to determine a competitive price per kW for the capacity savings that your project »

Four steps to effective energy management with ISO 50001 – step 3 Martin Hockaday, environment and energy sector manager at NQA, reviews the Plan, Do, Check, Act cycle of ISO 50001 and how it improves energy management Over the past two issues of we&e we reviewed Plan and Do of the Deming Cycle. This article addresses the third step of Check – or Checking, as ISO 50001 specifically states in section 4.6.

The adage “you can’t manage what you can’t measure” is the foundation of the Checking process; it is critical to ensuring the effectiveness of the energy management system (EnMS) and the deeper benefits of ISO 50001 cannot be achieved without it.

Monitoring, measurement and analysis This section of the standard helps to focus the scope and effort of the checking process. For some organisations it could be wide and deep, but the standard refers to significant energy uses.

The definition of significant will vary from business to business and that is fine as the standard is flexible to organisational size and complexity. The Energy Review from Step 1 should have identified these significant energy uses – most likely to be high cost or high carbon energy uses.

The monitoring activities are also completely flexible and could range from periodic reviewing of energy bills and readings from meters to specialist techniques such as thermography.

Importantly, the process should be planned, structured and repeated to ensure that the management system is effective and improvement objectives are being achieved.

Evaluation of compliance with legal and other requirements Legal compliance is fundamental, but for the evaluation to be effective we must refer back to Section 4.4.2 Legal Requirements. It seems obvious, but correct identification at the planning stage is crucial to a meaningful

Checking process and useable outputs.

Internal audit of the EnMS The intent of this requirement is the impartial and objective review of the energy management system and the activities it covers. This provides two different sets of benefits depending on the maturity of the EnMS: 1. Implementation – during the early phases of implementation, internal audits help to monitor progress, maintain focus and keep momentum.

2. Establishment – as the EnMS matures, the potential for diminishing returns increases.

Internal audits can uncover less obvious improvements such as staff behaviours and habits.

Non-conformities, corrective action and preventive action Corrective and preventive actions should be prioritised by magnitude and impact. The key requirement is that non-conformities to the requirements of ISO 50001 and the processes defined in the EnMS are corrected in an appropriate manner and timeframe.

Summary The importance of Checking shouldn’t be underestimated if you are serious about achieving the maximum benefit of the EnMS, particularly if accredited certification is an objective of implementing ISO 50001. The systematic identification of opportunities to improve will ensure that cost savings and other management objectives are achieved.

In the next issue of we&e, we’ll conclude our review with the final step of Act. This step puts improvements into action and re-starts the Plan-Do-Check-Act cycle.

ELECTRICITY DEMAND REDUCTION

Measurement & Verification – a core requirement for EDR

»

DECC is quite rightly keen to know how much electricity has been saved by the EDR pilot and Measurement and Verification (M&V) is a critical part of the application process. As this is not a widely used and understood discipline it is likely to be one of major technical challenges for some participants. An “M&V Manual” has been developed to guide participants in how to measure the savings from their projects, key elements are summarised below: Two key approaches to performance measurement are permissible under EDR. First, a “Deemed Savings” approach, which targets more straightforward projects – eg, a largescale swap out of a single product for a newer, more efficient model such as replacing halogen lighting with LEDs. A spread sheet is supplied to pre-determine the savings. This quick and easy approach to M&V does, however, only apply to a limited list of technologies and project types. The second approach for more complex projects uses “Full” or “Partial” M&V based on the good practice standard, IPMVP. Once you know which measurement approach is applicable, you will need to deliver three key outputs: 1. A Measurement & Verification Plan (M&V Plan) Submitted as part of the application process, the M&V Plan sets out “the how” in relation to your performance measurement process, ie, it sets out the methods and techniques that you will use to determine the project’s savings. It is necessary to complete this before the new equipment is installed. A template is provided to help participants produce the M&V Plan. This includes those using an approach involving the use of metering a critical part of which is the need to generate a baseline for site electricity use. The baseline is used as a ‘counterfactual’ (setting out how much electricity your site would have used had you done nothing) against which actual post-installation performance can be compared later on – the difference between the two is the saving attributable to the project. The Plan is also where you need to set out the evidence for your project’s payback and operation times during the winter peak period and how you will verify that the equipment has been installed (see Operational Verification below).

2. Operational Verification A post-installation requirement to evidence that the project has been installed and still meets EDR eligibility criteria. As set out above, the participant will have already detailed their proposed means of evidencing this in the M&V Plan (eg, using supplier receipts, commissioning sign off etc.). These commitments are triggered on project install and must be reported at the Operational Verification stage.

3. Savings Reporting Finally – and in order to receive EDR payment – there are two performance reporting requirements. Firstly, a Winter Capacity Savings Report which, again, must be submitted in accordance with the methods and procedures that were set out in the M&V Plan. It is this reported electricity savings figure that will determine 80% of the participant’s EDR payments. The remaining 20% is allocated on submission of a Final Report on which further details are to follow (submission of raw meter data is likely to be the key requirement).

will deliver during the winter peak period (as set out above).

If your bid is successful, this is the price you’ll receive.

Bidding closes on 12 January 2015 when DECC ranks the projects and the cheapest will be selected for funding, up to the point where the £10m budget is exhausted.

Stage 4: Participant Agreement – In return for funding the successful bidders are required to sign a Participant Agreement; a series of obligations including

undertaking Operational Verification of project savings (see M&V section for further information) to provide DECC with assurance that the equipment is installed, is working as intended and is delivering the expected capacity savings. Interestingly, if participants choose a deemed savings approach to M&V, the Participant Agreement means that those selected to take part in the evaluation will be required to give DECC

22 August/September 2014 | water energy & environment

access to the building(s) in order that they can install meters for the purpose of evaluating the Pilot.

Stage 5: Performance Reporting –As part of the above agreement successful participants need to provide proof that they have delivered the capacity savings they said they would. A Measurement & Verification Manual (produced with the help of EEVS and the Carbon Trust) sets out how to measure, verify and report these savings. The key

output is a Winter Capacity Savings Report, which must be submitted to DECC between 1 March and 15 April 2016. You will then be paid 80% of your bid in return (assuming you delivered them, that is). There are no additional payments for exceeding the savings amount in your bid. Payments are reduced for under-delivery.

Stage 6: Final Report – As this is a pilot, evaluation is a key government objective, not least to determine if EDR has a long-term future. As a result, up to 20% of payment is linked to your submission of a Final Report, which comprises two key elements: • 12 months of meter data (not required for deemed schemes); and • participation in the pilot evaluation activities and completion of a final evaluation questionnaire.

So there it is. While there certainly are a few hoops to jump through, but given the scale of projects we are talking about it is definitely worth considering if you have one. It’s also a groundbreaking scheme that hasn’t happened in the UK before.

There could be great PR and reputational benefits on top of the core energy and cost saving benefits.

One very clear practical barrier is the incredibly tight timescales the initiative is running to, but if an efficiency scheme that is shovel ready, or thereabouts, it might well be worth the effort.

ENERGY MANAGEMENT

New app-roach to software The UK is probably the most mature and crowded market place in the world for automatic monitoring and targeting products so what made Spanish company Dexma decide that its product would be good work here. Tim McManan-Smith got met up with UK managing director Steve Norman to find our why

D

exma formed in the UK in February 2013 and after a successful first year of trading it is looking to expand even further with its software that has the ability to be developed by the user as an app.

“Ultimately its all about data,” states Norman, “and you could use an excel spread sheet set up to produce the analysis that most monitoring and targeting software is able to perform. But the complexity as well as the potential for human error would mean that the energy manager would spend all of their time doing this. Software enables very quick gathering of data from sometimesdisparate systems and is able to integrate them seemlessly.”

“The thing that you have to realise with monitoring, metering and benchmarking,” continues Norman, “is that it is a tool; it enables understanding and to spot

where improvements can be made. It allows benchmarking and comparisons and prevents drift after energy reduction programmes have been implemented. Although it can be a really powerful tool and a necessary one to have a complete overview of energy efficiency projects within an organisation it won’t actually save a single kW of energy.”

Presenting data in the correct manner, such as with dashboards, has been an increasing part of the market but most do not address the issue of energy saving that effectively argues Norman. Although he does say that it can act as an aid to behavioural change, especially for those non-energy related staff.

The Dexcell system “Dexcell is our cloud-based systems that has all of the data in one place and allows analysis of this. It is particular adept at project based energy

Energy management software is like gym membership. If you don’t use it in the right way it won’t do anything for you

reduction programmes.

The software allows you to run projects with a time line to a measuring and verification standard such as IPMVP,” says Norman.

“How do you know if a payback that is quoted will be true? The ability of our system is that the repository of data is anomalously used to verify what others similar to you have done and how it panned out in the past. It is possible to conduct a virtual e-audit from past data that enables you to spot the best technology and manufacturers that would suit your particular future project”, comments Norman. The thing about exception reporting in general is that it spots waste but doesn’t tell you that you should change the lighting or the boiler says Norman.

Norman believes that you have to use the data in an effective and timely manner to get the best result from it.

“Energy management software is like gym membership. If you don’t use it in the right way it won’t do anything for you,” says Norman.

Although the UK is a mature market for energy management software Norman says that it is still only at the tip of the iceberg.

There are lots of companies who could be using software more effectively and many that would benefit by looking at their data differently.

Regarding ESOS Norman says that he believes that it does help energy managers because it works in the same way as energy managers do.

Unlike the CRC, for instance, which was a cap and trade,

theenergyst.com

carbon based scheme that recycled money and appealed to the finance department of the company. ESOS works on an energy management level and is all about identifying opportunities to save.

It’s all about the apps “The thing about the Dexma software – Dexcell; what makes it different to competitors, is that additional functionality can be obtained from apps.

“Dexma has an open API (application programming interface) so that anyone can devlop apps for the Dexcell system. You can devleop it in-house, get another party to develop it or Dexma is able to assist too. You keep the IP for the developed app and can sell it to all of our other customers if you wish to on

theenergyst.com

our app store,” states Norman.

An example of the sort of app that has been developed would be an app to utilise BMS functionality to, for instance, change the lighting from the Dexcell systems directly.

Norman believes that the apps will help Dexcell become the product to standardise on.

He can see 500 apps available within the next year. Dexcell’s job is to capture, store and deliver data in the best way possible, others are then able to add further functionality to this offering through the development of apps.

“Data for your company is pre-processed in all the time needs that you require and stored in these time dimensions; minutes, hours, weeks, years and so on. This increases the speed of data retrieval

significantly,” says Norman.

Dexcell will integrate directly with the manufacturer’s hardware., this is important as people want a single place to look at all of their data.

Another benefit of Dexcell is that SMEs are catered for as much as I&C companies because the only licensing element that Dexma charges for is the data points that it has to store and not user numbers. “I am confident that some customers will understand with certain systems they are being charged for both volume and users numbers and realise that they are being double charged,” comments Norman. dexmatech.com

VIEWPOINT

Increasing efficiency to cut generation capacity

T

Richard Hipkiss looks at a new government scheme to try to reduce overall energy demand in the UK (EDR) – and which can save businesses money too

hey do say that there is nothing new under the sun but good ideas have a habit of reappearing in different guises. For example, the idea that investment in energy efficiency can offset the need for new electricity generation capacity is not new. In the US several decades ago, utilities were handing out energyefficient lightbulbs in their thousands to avoid the costs of expensive infrastructure construction. And in some states there were laws to make power companies minimise consumption before any new plants were authorised.

That idea may have taken some time to make the journey eastwards across the Atlantic, but it has finally arrived (although not in terms of compulsory programmes) in the shape of the Energy Demand Reduction (EDR) pilot.

The government will be “testing whether projects that deliver lasting electricity savings at peak times (in kW) – for example, by replacing old bulbs with LEDs or improving motors and pumps – could in future compete with generation, demand side response and storage in the forthcoming GB Capacity Market”, according to its website.

Virtually all of us in the energy management industry could provide the answer already. However, the promise of financial support in order to gather more evidence is always welcome. Though we may

be convinced that it works, the promise of lower overall costs can help persuade others in the organisation to take a closer look.

There is not much time to act, though, if you want a share in the £10m on offer. Formal expressions of interest have to be received by the Department for Energy & Climate Change by 30 September and completed applications (including a measurement and verification plan) by 31 October. This pilot scheme is open to private and public sector organisations as well as voluntary bodies.

Where the programme is novel is that it takes the form of an auction. In other words, funding for projects will be awarded on a competitive process of judging how they stack up in terms of value for money.

Participants can bid in for Funding available in kW savings first Energy Demand to be gained Reduction pilot from the auction projects they are planning.

The lower the price for each kW saved, the more likely the project is to win funding. The grants will be awarded starting with the projects with the lowest cost per kW saving, rising through progressively more expensive projects up to the limit of the funding. Successful bidders will receive payments once savings are delivered and evidence received. Participants will be selected at the auction

£10m

in January 2015 and money released after the submission of final reports which are due to be submitted by April 2016.

Not all types of energy saving projects are eligible, though – only those which produce savings through the installation of more efficient electrical equipment. For organisations that are interested in looking at participating, ESTA members will be happy to advise on both the technologies available, such as more efficient lighting systems or variable speed drives, as well as the likely savings that can be achieved.

If the first EDR pilot proves successful – there is £10m on offer for the first auction in January 2015 – the government says, somewhat guardedly, that a further auction “may follow”. So it really is up to energy users to ensure a successful first phase, providing the justification for further spending. More than £20m has, nominally, been allocated to the scheme.

For energy managers facing the perennial struggle to get senior management to buyin to the concept of greater investment in energy efficiency, the promise of government money on the table to offset the associated costs provides another argument when talking to colleagues. we&e Richard Hipkiss is chairman of the Energy Services and Technology Association.

ENERGY MANAGEMENT

The benefits of hindsight How can you prove energy savings if you only had sparse energy data before the project, asks Vilnis Vesma

W

hen people ask me for advice on how to verify energy savings, it is often because their own analysis is not giving the results they expected. Often they have left it too late, developing a methodology after the event and making it up as they go along.

So if you are contemplating an energy-saving project, the first plea I would make is this: agree a measurement and verification plan between the interested parties before the project starts. That way, everyone is forced to think about the calculation methodology and (just as importantly) focus on what data will be needed, who will collect it, and even how much uncertainty there is likely to be in the conclusions.

Incidentally it also pays to think about what non-routine changes might happen (patterns of occupation, extensions, demolitions, etc) and agree how those will be dealt with if they occur.

Now consider that in a normal evaluation, accurate and complete pre-project baseline data are needed so as to establish the prior relationship between consumption and relevant independent driving factors (such as degree days, hours of darkness, production and so on). Both consumption and driving-factor data must be available at regular (typically weekly or monthly) intervals spanning a wide range of operating conditions. A formula would be derived, typically using regression analysis, for relating

“

Agree a measurement and verification plan between the interested parties before the project starts

28 August/September 2014 | water energy & environment

consumption to those driving factors. Then, after the energy conservation measure (ECM) has been installed, that same formula can be fed with driving-factor data and will yield an estimate of what consumption would have been in the absence of the ECM. The spread between this estimate and actual consumption is a measure of the “avoided” energy consumption.

It is quite common, however, for the pre-ECM consumption data to be erratic, estimated or sparse, preventing the development of a baseline performance model.

Fortunately, this situation can be rescued if there are at least two firm pre-ECM meter readings spaced well apart (a year between them, for instance) as long as both sides are willing to accept a retrospective definition of procedure, and if regular and accurate consumption records are kept after the ECM. In these circumstances savings can be estimated using a technique called “backcasting”.

Backcasting turns the normal process on its head. Using the regular post-ECM data a formula is developed which relates consumption to driving factors for the improved installation (rather than its original performance),. In this scenario, pre-ECM actual consumptions are compared with what they would have been if the ECM had been active all along, and one would expect those actual consumptions to be higher than the model’s predictions.

This is the opposite of the

conventional approach where post-ECM consumptions turn out lower than the baseline model predicts.

To make backcasting work you need driving-factor data spanning exactly the entire period between the pre-ECM meter readings. This should not usually be a problem: weather data can be accessed readily, and production statistics (if relevant) would normally have been recorded for other purposes. The expected-consumption formula, although classically applied interval by interval, will readily yield an aggregated estimate over any number of time intervals.

The only sticking-point is when you try to infer what percentage savings you can actually claim: you might need to be able to extrapolate from, say, seven months’ inferred savings under particular conditions to a full year under standardised conditions.

Space limitations preclude a full explanation, but the answer lies in agreeing how the ECM was likely to affect fixed and variable demand respectively. As is so often the case with measurement and verification, this will call for a mix of technical argument and a willingness on both sides to agree on a plausible and fair solution. we&e Vilnis Vesma (vilnis@vesma. com) is a specialist in the analysis and interpretation of energy data.

ESOS AND BEHAVIOURAL CHANGE

From here to obliquity?

Tim McManan-Smith met up with John Mulholland to talk about ESOS and how motivating people is sometimes not as straightforward as you may think

T

he interface between energy and people is where the energy savings can be made according John Mulholland, principal consultant at Mulholland Energy Solutions.

There is a triangle between people, information and technology and all three need addressing all of the time.

In many orgainsation the people are DRIP (data rich information poor) and it is getting them to access the right information and use it to reduce energy rather than being paralysed by so much information much of which isn’t essential to the job.

Mulholland beleives that there are four steps to saving energy and it starts with the people.

1. Good house keeping 2. Process procedures; don’t leave on big machine for the next shift 3. Maintenance; fix compressed air leaks and so on 4. Investment opportunities.

The way to get changes in behaviour to persist is by understanding the reason why something is being done rather than just being told to do it. “to achieve consistent behavioural change it must come from inside and not an external influence,” says Mulholland.

“There have been studies that show that people respond to peer pressure and they do,” comments Mulholland, “however, there is a magnetic middle, those below tend to improve while those above take their foot of the gas and drift towards to average.” It is by understanding phenomena

such as this that we gain an insight into how people inteface with each other and technology and how best we can achieve a result that produces lasting reduction in energy consumption.

“The graph from the Carbon Disclosure Project (above) demonstrates how powerful behavioural change can be,” comments Mulholland, “yes there are big technology wins too such as refrigerants. But in terms of getting the best ROI it is really up there.”

Obliquity Obliquity is a theory that proposes the best way to achieve a goal when you are working with a complex system is to take an indirect approach instead of a direct one. Mulholland beleives that this approach can prove very fruitful when looking at behavioural change and energy saving.

Mulholland explains, “If

30 August/September 2014 | water energy & environment

the simple rouite is A to B and I’ll use the example of reusing towels in a hotel room. The hotel wants you to reuse the towel to save on laundering, so they tell the guest that it will enable them to use less water, energy and detergent. But this direct message doesn’t often work for the majority of customers, about 40% reponded to this environmental messaging. So you have to use an oblique

Sponsored column

way of getting from A to B which is via C, another message. By telling people that most othre guests recycled and even the the majority who used this room recycled their towels the uptake was 66%.”

So by using peer pressure rather than a direct approach allowed them to achieve A to B anyway. It is a way to achieve sustainability by stealth, whereby people do the right thing but maybe not for the same reason as the person next to them.

Its about finding the right thing to motivate them.

The good and bad of ESOS “I think that ESOS is vague in its guidance for audits,” says Mulholland. “there are only 3 main strands and these are not fully expounded upon.

1 Find your overall energy 2 Opportunities for reductions 3 Report this to the Environment Agency “However, one of the plus points of the guidance is that ESOS requires net present value and internal rate of return type of calculations and not simple payback periods.” The takes people and their companies into a different way of thinking than many do at the moment and should help them see the best opportunities that exist.

Mulholland says that in the ESOS guiance notes all numbers are wrong in the example regarding LifeCycle Cost Analysis because in the zero year there are cost attrinuted to it. “There is no energy use just the investment as you have not yet turned it on at zero but after the first year of running only then do you have a year’s worth of energy use to factor into the calculations,” comments Mulholland.

“Energy efficiency survey schemes have existed in the past such as The Carbon Trust’s that were 100% funded

by Government yet the recommendations were not

theenergyst.com

implemented. ESOS has more chance of being implemented because it is paid for by the business and they will want to see a return and it is also a legal obligation to get it conducted in the first place,” comments Mulholland.

“It is definitely better than doing nothing,” he continues, “If it pushes people towards ISO 50001 so that they are compliant then this is a good thing.

Around 50% of all ISO 50001 certificates are in Germany and this is due to the fact that their Government gives businesses a tax break from the renewables energy taxes that exist over there if they have the standard. So anything that makes UK companies think and act on the issue of energy saving is welcome.

“There is good legislation behind it and it will reveal opportunities that would otherwise not have been seen. It has board level sign off and pushes beyond simple payback. All in all I am optimistic about this.”

One thing that stands out as having being low on ambition is DECC’s claim that the audits will lead to a 0.7% saving per organisation. “This is a bit silly as it is far too low,” comments Mulholland, “But even this yields a £0.8bn£3bn saving every year.

When I asked generally why we are not more successful at energy efficiency Mulholland replied that, “We do energy efficiency because everyone agrees that it is good and sees the benefits. It’s a no brainer and so unfortunately we don’t use our brains and the obvious is tripped up by irrational behaviour of people and their use of the technology around them. There is no joined up thinking between technology and behavioural science.”And this is exactly what Mulholland is trying to change.

John Mulholland will be speaking at the Energy Event on 17 Sepetmber

We’re on the latest loop of the energy roller coaster In the first of his regular columns Dave Cockshott, board director at the Inenco Group, looks at the ever-changing landscape in the sector I began my career in the energy industry as an electricity purchasing manager at Inenco in 1990. Almost 25 years later (yes, I too baulk at the fact it’s been that long) and following a variety of roles in the industry, I’ve returned to the Inenco Group as a main board director, responsible for sales and marketing among other things for its industrial and commercial clients in the UK and Europe.

Working on both the supply side and for Third Party Intermediates (TPIs) has given me the unique perspective to witness first-hand the huge volume and breadth of changes to the energy landscape.

Twenty-five years ago the main focus was simply selecting the right tariff and later helping large businesses to procure energy through straightforward fixed price contracts. The notion of an “energy manager” was almost unheard of.

Now, every aspect of the market has become more complex, creating an increasing workload for the now-vital energy manager who may be responsible for energy compliance, energy buying and carbon reduction all at the same time.

From deregulation to the impact of policy on businesses, the cost of Electricity Market Reform to the ever-changing carbon legislation, one thing is for sure: it has been a rollercoaster ride for us all and the impact of cost and competitiveness on businesses has certainly taken its toll. Despite the current stable market prices, who knows what’s next.

As the needs of energy managers have had changed, so too has the role of an energy

consultant. The age-old formula that “energy cost = volume x price” is more fitting now than ever before, yet it amazes me that energy procurement and management is still not fully integrated in many businesses.

We are all here to help our clients to manage their costs by integrating carbon and price strategies. Those that don’t are sure to struggle with volume exposure – and in a climate where businesses face external pressures from every direction, why overlook an opportunity to reduce cost wherever possible?

The introduction of the Energy Savings Obligation Scheme (ESOS) could be the catalyst for this change. It feels a bit like the car seatbelt law in the 1980s: it’s a shame we needed a law for our own good, but now it’s here it should soon become the norm and rather than a pain, it will provide benefits for all who comply with it.

In this column I’ll be aiming to use my perspective of two and a half decades working on both sides of the fence to air some of the issues and debate the topics that impact on the energy sector. In the meantime, I’ll be at the Energy Event at the NEC in Birmingham.

Do drop in to Inenco’s ESOS coffee bar and say hello.

ESOS NEWS

Businesses can’t afford to ignore ESOS

T

Phase one of ESOS is in full swing. David Cockshott, sales and marketing director at Inenco, stresses the importance of taking action and getting a head start

he Energy Saving Opportunities Scheme (ESOS) is finally here, meaning thousands of businesses will have to complete mandatory energy audits by December 2015 at the latest.

Tempting though it may seem for businesses to bury their heads in the sand or write this off as simply another carbon tax, noncompliance is not an option and the timescales for ESOS are demanding. Businesses need to act now as any delay in taking action could mean

that savings of millions of pounds go unrealised.

Get ahead of the game The winners in ESOS will be those businesses that take an early lead in completing audits and unlocking savings.

Unlike other energy legislation introduced in recent years, ESOS is a chance for businesses to go beyond their property portfolio and realise significant cost and carbon savings across their operations.

ESOS audits are mandatory, yet acting on the

recommendations is not.

However, according to the Department of Energy & Climate Change , those businesses eligible for Number of times ESOS could over DECC estimates make a combined that ESOS will saving of pay for itself ÂŁ300m by 2016. The Carbon Trust believed that figure could actually be threefold, making ESOS a major opportunity for businesses to grab with both hands rather than a burden to view with scepticism.

Finding your way to energy saving opportunites and acting on them is the key to success in ESOS

32 August/September 2014 | water energy & environment

Take a strategic approach The key to maximising opportunities from ESOS will be going beyond simple compliance and focusing on getting best value out of audits. There is a clear difference between pointing out where LED light bulbs could be fitted, and taking a more strategic approach to identify hidden sources of energy waste.

ESOS also requires signoff at director level, meaning energy gets the board-level attention it deserves and buy-in to act on identified opportunities can be sought at the most senior reaches of a business.

However, the capacity to deliver good quality audits is restricted: with more than 7,000 scheme participants and about 500 accredited and experienced professionals, demand may well outstrip supply closer to the ESOS deadline.

Companies that leave it too

theenergyst.com

1. What is ESOS? close to the deadline risk overpaying for their audit or failing to comply on time, as well as missing out on an opportunity to take a strategic approach to the audits.

Unlock savings through integration ESOS is about more than compliance. If done correctly, the process will identify cost savings, which will offset the cost of the scheme (in fact, DECC believes ESOS has the potential to pay for itself 13 times over).

However, businesses must integrate ESOS with their wider energy procurement strategy to successfully reduce cost as well consumption. As with all energy reduction projects, projected savings must inform future purchasing decisions to avoid the introduction of unnecessary energy volume risk into the business.

Don’t delay There is still time to avoid bottlenecks and take advantage of early ESOS compliance to begin the implementation of energy saving recommendations that will recover the cost of compliance and more – but make no mistake, ESOS timescales are demanding and businesses need to act now.

There is still time‌ but make no mistake, ESOS timescales are demanding and businesses need to act now

ESOS is a mandatory scheme that will apply to up to 10,000 of the UK’s largest businesses. DECC formally announced ESOS in June 2014 and its introduction will ensure that the UK complies with the EU Energy Efficiency Directive.

Under ESOS, all eligible businesses must complete a mandatory energy audit within the next 18 months to identify energy savings. Businesses that fail to comply will face fines of at least ÂŁ45,000.

Businesses must assess their qualification status by 31 December 2014 – and those who qualify will need to submit their ESOS audits and paperwork by 5 December 2015. Audits will then have to take place every four years from 2015 onwards.

2. Who does ESOS apply to?

Britain’s biggest companies will be required to comply with ESOS. The criteria affects businesses which: t IBWF NPSF UIBO FNQMPZFFT PS t IBWF BO BOOVBM UVSOPWFS PG BU MFBTU b N BOE BO BOOVBM balance sheet of £36.5m+ balance sheet for the financial year ending December 2014

3. What does it involve?

ESOS NEWS

Take the easiest route to compliance The new ESOS mandatory energy auditing scheme has arrived, with the first reports due at the end of 2015. ESOS has the laudable aim of helping the EU meet its target of reducing energy consumption by 20% by 2020 – but will we see businesses buy in to this new scheme, asks Brian Rickerby

R

ealistically, and in some ways understandably, many organisations will not be considering any of the potential benefits of the scheme. Instead, they will be thinking: “How do I comply Data is the key to ESOS with this legislation as cheaply and expediently as possible?”

Scheme can be used, at least This may sound cynical, in part, for the purposes of but the scheme is designed determining total energy to force organisations to consumption as part of identify how they could save an ESOS Assessment. energy. There is nothing in Submitting a DEC for certain the legislation forcing them buildings could prove a to implement any cost-saving more cost effective route to measures, which I believe compliance on a particular is a fundamental flaw in building – so why not use the legislation. However, what is available to you? the scheme is here and There may also be areas of energyTEAM’s approach energy consumption that are will be to help organisations difficult to quantify but could comply, where possible be excluded under using other existing what is called the schemes or “De Minimus” collated data rule, as once that may you have or may not determined Amount of your already be your total energy consumption energy in place within your consumption, that needs to be organisation. you are only audited For example, a required to audit growing number of assets and activities organisations are being that amount to 90% of asked to demonstrate their this (your areas of significant energy reduction credentials energy consumption). by their customers and/or I would stress that what stakeholders.

need a comprehensive understanding of your organisation’s structure, processes and associated energy use. Note ESOS covers all electricity, gas and fuel oil used including transport.

A detailed energy audit will then need to be prepared and verified by a lead assessor that is certified by an approved accreditation body, yet to be confirmed by the Environment Agency.

Lead assessors must also review your ESOS assessment as a whole. The ESOS guidance states clearly that complying with the scheme should involve identifying specific and cost-effective energy saving measures.

A key point about the scheme is that audit has to be signed off at board level before being submitted – there is no place to hide. ESOS sets minimum requirements for compliant ESOS energy audits such as BS EN 16247 Energy Audits. However, with a decent ESOS audit, the board will know what measures it can take and will have to have a good reason to do so.

We firmly believe that these recommendations should be detailed, comprehensive and where feasible, fully costed, or they will almost certainly not be acted on – and that will be an opportunity lost.

Directors need to know how much any initiative will cost, how much it will save and what the payback timescales are. If they can see the estimated costs and benefits of all the actions recommended, they can make

“

The real target audience for an audit is the board, not a government department informed choices about what to implement in which budget cycle, and it is more likely that they will actually commit to the changes suggested.

Putting cynicism to one side, if, as predicted by the government, the scheme leads to £1.7bn net benefits to the UK, it will no doubt be welcomed with hindsight.

For now, however, the overwhelming feedback we get from businesses is that after waiting for clarification on how the scheme will work for so long, many now see it as just more red tape.

In truth, I have been as sceptical as the next man about ESOS, because I feared that all it will generate is more reports gathering dust on the shelf. However, the scheme has arrived and energyTEAM’s approach now is to raise awareness of what needs to be done to comply with ESOS, using whatever data and expedient measures are available but without losing sight of what makes for a quality audit.

The real target audience for an audit is the board, not a government department. we&e Brian Rickerby is joint managing director at energyTEAM energyteam.co.uk

ENERGY MANAGEMENT

National energy investment panel Commercial law firm Muckle LLP has been appointed to a national panel to advise Sustainable Development Capital LLP (SDCL), the manager of a specialist energy efficiency fund into which the UK government’s Green Investment Bank (GIB) has made a £50m commitment

T

he Energy Team at Muckle won its place on the SDCL energy inesvetment panel by demonstrating value for money, project management skills, working efficiently with other advisers and commitment to growing the energy efficiency, microgeneration and sustainable urban infrastructure sector.

Since being appointed to the panel, Muckle has already completed a deal involving a £2m investment into ReEnergise Finance’s Smart Energy Finance vehicle, which has been set up to provide loans, primarily to SMEs in the North East and across the UK, for energy efficiency projects.

Initial loans are in progress for biomass and lighting projects for a variety of organisations including a garden centre and a training provider. The investment could eventually build a portfolio of up to £10m of assets. Typical projects will be from £25,000 to £400,000 and could include biomass boilers, low energy lighting and combined heat and power, as well as other energy efficiency and micro generation technologies.

GIB, through the SDCL fund, has provided £1m of the funding, matched by £1m from SI Capital R&S1.

The funding model means businesses will start saving money from day one, with an immediate reduction in their energy bills of about 20%.

In respect of the Reenergise investment, Shaun

theenergyst.com

Kingsbury, chief executive, of GIB, said: “The investment announced today will help small businesses across the country to save money. Energy is a significant cost for any company, and putting in place energy efficiency measures will have a real impact on these organisations’ bottom line.

The funding model means that they won’t need to find the capital upfront, and can pay for the capital costs from the savings they make on energy bills. Energy efficiency makes good commercial and environmental sense.”

Jonathan Maxwell, CEO, Sustainable Development Capital and Jim Totty, partner of SDCL EE Co (UK) LLP, said: “For a long time we have been seeing high quality dealflow for energy efficiency projects for small commercial premises.

These include biomass boilers, lighting retrofits, and other efficiency retrofits.

“However evaluating and structuring bespoke small energy efficiency investments into the SME sector is a challenge for investors.

ReEnergise offers a unique combination of experience and energy efficiency sector knowledge to allow us to deploy capital quickly and efficiently and we look forward to working with Adam Hewson, Tarquin Henderson and the ReEnergise team.”

Chris Garside, legal and commercial director of Sustainable Development Capital, said: “We are delighted to appoint Muckle to our legal panel. The firm demonstrates enthusiasm and

skill in the energy efficiency and micro-generation sector.

“SDCL is committed to investing in energy efficiency projects in every part of the UK, including the North East.

This appointment is part of our aim to build partnerships that help deliver that commitment.

The North East is at the forefront of the new energy revolution and our investment should help to ensure that economic growth and carbon reduction are delivered hand in hand, with local supply chains rising to the challenge of servicing the sector.”

Lucilla Waugh, partner in Muckle’s energy team, said: “We are delighted to be appointed, which is fantastic recognition of our expertise in this sector. We have already completed one project for SDCL and are already actively advising on a separate LED investment project. We welcome any approaches from businesses who are interested in funding for energy efficiency schemes.”

Efficient HVAC solutions Airedale International, returns to this year’s Energy Event with more energy-saving solutions - from awardwinning cooling systems to a range of retrofit solutions, all of which will generate energy efficiencies and reduce operational costs.

The British manufacturer will be showcasing its SmartCool high efficiency dedicated chilled water (CW) precision air conditioning (PAC) system (11-233kW) which is claimed to deliver up to 30% more cooling kW/ m2 than its nearest rival.

Airedale’s TurboChill and TurboChill FreeCool chiller (200-1830kW) is now available with low global warming potential (GWP) refrigerant R1234ze, well ahead of the impending phase-down of higher GWP refrigerants such as R134a traditionally used in cooling products. The first TurboChill with R1234ze is now cooling shoppers in John Lewis’ most sustainable store which opened in York in April.

Among the energy-saving retrofit options available from Airedale are potential 70% power savings by upgrading from AC to EC (Electronically Commutated) fans on air conditioning systems, with a typical payback period of

under two years. The direct drive fans also remove the need for belt replacement, reducing maintenance costs and increasing uptime.

Integrating Airedale controls will improve energy efficiency further by precisely matching speed to demand.

Other retrofit solutions include electronic expansion valves (EEVs) which can reduce energy consumption by up to 30% when fitted on Airedale or other manufacturers’ equipment.

Another way to improve efficiency is to upgrade to Airedale’s ACIS building energy management system (BEMS) which optimises a wide range of building services across multiple platforms and protocols. Fully scalable, ACIS allows you to control and sequence system performance, availability and power draw, and provides you with valuable energy analysis, remote monitoring, reporting and diagnostic tools giving you full visibility of plant. Through the software, temperature set points can also be adjusted, maximising time spent in energy-saving free cooling mode and reducing the need for more costly mechanical cooling. www.airedale.com

Upgrading from AC to EC fans can reduce power input by up to 70% (comparisons with AC fan equivalents at part-load conditions)

Could ISO 50001 change the way you look at energy?

By Louise Powell Responsible for energy management? Not sure where to start? Or maybe you’ve identified all the quick wins but don’t know what to focus on next?

ISO 50001 could be the answer you’ve been looking for. The international energy management standard is designed to help energy managers to develop a structured and methodical approach to managing energy.

The number of organisations using ISO 50001 is rising, particularly following the launch of the Energy Savings Opportunity Scheme (ESOS) at the end of June.

However, the question that most energy managers want answered is, how can ISO 50001 help me in my day-to-day role?

Providing clarity

Whether you have very limited means by which to monitor the amount of energy being used or are simply overwhelmed with too much data, the ISO 50001 framework can provide you with greater clarity of where energy is being used and wasted within your organisation.

It can also help to identify and prioritise energy efficiency projects, from low-cost measures such as changing operational controls, through to more expensive technology investments.

Regular monitoring of energy use, setting reduction targets, and comparing actual consumption against predicted values all help to focus attention on the areas where energy, and therefore cost, savings can be made.

ISO 50001 provides a flexible approach that allows companies to tailor their management

systems to suit their own unique environments. And by using the ISO 50001 framework, organisations save on average between 10-20% of their energy use.

Where to start

The first step is to conduct a Gap Analysis to see how your current processes compare with the requirements of the standard.

As Duncan Mottershead, engineering director at Anglian Home Improvements, explains, “conducting a Gap Analysis was a very important first step for us as it helped us to understand how much time and effort was required to achieve certification and where we needed to focus our attention”.

Louise Powell is business development manager at Gemserv. Gemserv works with organisations to develop bespoke ISO 50001 certified energy management systems.

For more information, to book a free Gap Analysis consultation, or to book a one-to-one session with us at The Energy Event in Birmingham on 16 and 17 September, contact one of our team on 020 7090 1022 or email iso@gemserv.com

The government has also stated it will publish guidance to assist applicants in understanding what changes are likely to be considered “material” or “non-material”. While both can be accommodated, the Bill currently being debated makes it clear that this is not a panacea. The secretary of state would retain a discretion to refuse an application for a modification of a DCO where he considers it should properly be the subject of a full DCO application.

THE ENERGY EVENT

EMR is in the endgame, but it’s not the end of energy market change The low-key announcement by the European Commission on 23 July marked a major milestone in the Electricity Market Reform programme. The contract for difference for low carbon power and the capacity market to maintain security of supply have now received state aid approval, writes Jonathan Brearley

N

othing is certain, especially in UK energy, but in my view the announcement by the European Commission on 23 July was the last big milestone before implementation and therefore, after four years of debate and development, like it or not, we now know that the Energy Market Reform instruments will come into effect later this year.

Investors, companies and developers should already have their planning well under way as to how to respond to each.

For example, we will all need to get our bidding strategy in shape for the capacity and the contracts for difference auctions. We will need to know our own internal hurdle rates and how this translates to prices.

Equally those who want longterm contracts will need to make a decision on whether to lock in prices from this year’s auctions versus waiting for the prices that they may get in next year’s auctions.

This is further complicated by the risk of further (more incremental) changes in auction/ contract design between this year and next.

If this were not enough to consider, energy has been front page news over the past few years and this is likely to continue. An election, the Competition and Markets Authority Review,

“

Customers, and the UK government as their proxy, will pay what is needed to keep the lights on the possibility of an exit from Europe and an independent Scotland mean the scenarios for the future market remain broad and uncertain, with the likelihood that further big changes lie ahead.

The interaction between each of the list above will drive the shape and structure of any future market. For example, the CMA Review may have very different

44 August/September 2014 | water energy & environment

implications under a Labour government that has already defined what it believes are the necessary reforms to the energy market than it would under the Conservatives.

Equally, the renewables industry in the 2020s will depend on the shape of manifestos going into the election and the party or parties that win.

Investors, companies and developers will need to get a clear handle on the shape of these different scenarios and the implications for their existing plants, their fuel supplies, their customers and their future projects.

With all of this change, there are two fundamentals that we can hold on to.

The first is the knowledge

that investment is crucial – no government will want to preside over a security of supply crisis. Through EMR, investors should see sufficiently high prices to get the necessary investment in place. This does not mean all projects will “win” but customers, and the UK government as their proxy, will pay what is needed to keep the lights on.

Secondly, energy is firmly a public policy issue and therefore the government and the regulator will remain heavily involved in the ongoing shape and nature of the energy market.

As a result, companies need to do all the things that have been part of the energy industry for years; knowing your customers, identifying and developing energy projects and driving efficiencies across the board.

However, to really succeed and become a part of this national investment project, companies and their investors need to understand public policy and the politics behind it to a much greater extent than ever before. we&e Jonathan Brearley is a consultant for Brearley Economics and is the former director of energy strategy and futures for the Department of Energy and Climate Change.

THE ENERGY EVENT

Savings that need to stack-up New regulations will again raise energy to boardroom level and the onus will be on energy managers and facilities managers to identify opportunities and justify the investment, says Geoff Newman, business development director of Sabien Technology

M

any organisations are being faced with new regulations that will require them to disclose their energy consumption and areas for further energyefficiency measures, over and above those that may already have been delivered.

This situation can only increase pressure on those responsible for energy management to identify energy-saving opportunities that not only reduce energy consumption but also “stack up” financially in terms of providing a cost benefit. Ultimately it provides organisations with opportunities to improve their financial performance as well as their Corporate Social Responsibility.

Organisations classified as “large undertakings” will fall within the remit of the Energy Savings Opportunity Scheme (ESOS), requiring them to assess their energy use and the potential for energy reduction, and submit evidence to the Environment Agency. This includes all organisations employing more

than 250 people or having an annual turnover in excess of €50m and balance sheet assets exceeding €43m.

One way to comply with the ESOS regulations is to achieve certification to ISO 50001 but, as with all ISO standards, there is a requirement for continuous, verifiable improvement which will require funding.

In addition, all privately rented commercial buildings will be required to meet minimum energy efficiency standards from April 2018 as part of the Energy Act 2011.

Strengthening the business case For those organisations that have already implemented energy-saving programmes the requirement for even greater efficiencies is a challenge. Not just because of the need to identify new opportunities but also in terms of gaining further investment – particularly if significant investment has already been made.

One of the key factors here is to be able to produce a strong business case for the

organisation’s financial team that looks beyond a simple payback and assesses the full cost benefits For example, when boiler load controls are installed, the primary financial benefit is a reduction in gas consumption. However, when reduced CRC costs, extended lifecycle of the boilers, reduced electrical spend due to reduced burner firing and reduced running of pumps are included the business case becomes very compelling – both from a payback and an ROI point of view.

Consequently, you may find that your energy efficiency

Savings for direct fired water heaters Domestic hot water systems that use stored hot water typically employ a control strategy that routinely pasteurises the water. In the case of direct-fired water heaters this procedure can create inefficiencies and lead to unnecessary energy costs through short cycling. A new control technology, designated M1G, is able to differentiate between short cycling and a true demand for hot water and therefore prevent energy wastage. The M1G system is fully adaptive and measures demand in real time to increase the energy efficiency of your existing direct-fired water heaters without any changes to your stored water temperatures.

project will be delivering a better internal rate of return than other projects within your organisation. Once the financial team and board see this (in their language) it will be hard for them not to allocate the budget and prioritise the project.

A key element of this is having confidence that any proposed measures will deliver what they promise and that any benefits can be independently verified.

Ideally, such cost benefits should also be delivered within a relatively short space of time. For instance, the compliance period for ESOS is every four years so it will be important to demonstrate savings within each of those compliance periods.

Further information about achieving a relatively fast return on investment from energy efficiency technology, and how these benefits can be verified to support your business cases, can be found on the Sabien Technology stand, B59. we&e sabien-tech.co.uk

GAS & ELECTRICITY

‘Open for Businesses’ Creating innovative energy products that our customers want, delivering an excellent customer experience, and providing transparent products and solutions backed up by relevant, timely support. We are Open for Businesses by Sion Roberts, Director, Commercial

P

art of the Total Group of companies (one of the world’s top 5 international oil and gas companies), Total Gas & Power is a specialist provider of energy to UK businesses and supplies the largest volume of gas to the industrial and commercial sector (Cornwall Energy reports – May 2014).

We supply approximately 100,000 sites across the entire commercial and industrial spectrum in the UK with gas, electricity, or both.

One of the key factors in our growth has been our commitment to transparency and long-term relationships with customers. We have established a reputation for innovation, value-added services and working with customers to help them monitor, manage and optimise energy usage. We also identify opportunities for energy efficiency and on-site generation, and implement sustainable solutions that deliver quantifiable energy and carbon savings.

We’re calling our approach “Open for Businesses”.

What does this mean practically?

We have always offered competitive fixed term products and basket deals but what sets us apart are our procurement options that match our customers’ strategies for risk management as well as growth. We can provide the right risk management approach for you – whether it be fixed price, indexed fully flexible or managed; even insurance

against cold weather.

When our commercial customers requested a risk management product that incorporated triggers, enabling them to achieve the best gas market rate possible, we created Cap & Benefit. The ‘upper’ and ‘lower’ triggers activate a call from our Procurement experts based in Canary Wharf to discuss what action, if any, should be taken to optimise our customers’ procurement position.

Our Procurement experts form part of the service that all of our key account customers

50 August/September 2014 | water energy & environment

receive by acting as a support function to empower our customers to make timely and informed decisions by sending regular market reports and bespoke account reports.

The value they provide is represented by the outstanding rating they consistently receive in our annual customer satisfaction survey.

Our ground-breaking alliance with Jules Energy has created a UK first. This energy procurement platform is a unique online system that enables customers to sell the electricity that they

have generated. We have also developed guaranteed energy efficiency programmes and Power/Gas Purchase Agreements tailored for all types of renewable and low carbon generation, solar, and biogas production to help customers optimise their revenue and reduce consumption.

Our customers benefit from robust Service Level Agreements (SLAs), covering business critical areas including invoice delivery, query resolution, performance reviews and siteworks.

As members of the Institute of Customer Service, we also believe customers get the best account management when they are supported by a dedicated team and have one point of contact. Regular management information is provided and face to face meetings are encouraged to help cement the relationship.

In recognition of our efforts, we have been shortlisted in this year’s “Energy Supplier of the Year – Industrial and Commercial” category of The Energy Awards.

Moving forward The future for Total Gas & Power sees persistent innovation, a focus on renewable energy, a commitment to excellent service, and ongoing support for our customers as they look to drive energy costs out of their businesses whether by demand reduction or risk management.

THE RENEWABLES EVENT

Microgeneration solutions on show The Renewables Event, the UK’s only conference and exhibition dedicated to onsite renewable energy generation, will return to the Birmingham NEC this September (16 to 17)

N

ow in its third year, The Renewables Event will welcome more than 6,000 visitors looking to network with their peers and the 50 plus exhibitors. The freeto-attend CPD-accredited conference programme also features 15 seminar sessions, with panel discussions and case studies from some of the key decision makers developing onsite renewables in public sector organisations.

With the renewable energy landscape constantly evolving, and with the introduction of new policies and incentives, such as The Solar Strategy and Non-Domestic RHI Scheme, it is more important than ever to stay abreast of the latest sustainable initiatives.

This year’s show is a must attend event for anyone responsible for sustainable initiatives and utilities management in buildings.

Exhibitor highlights This year’s exhibitor lineup will showcase products and technologies from the full microgeneration spectrum, including wind, biogas/biomass, geothermal, hydropower, solar PV and solar thermal energy. From the country’s fastest growing energy solutions businesses, to industry leaders in biogas plant production, this year’s event is the perfect chance to learn, buy and network.

Key exhibitors include Siemens Financial Services, Solarsense, Total Gas & Power, Viessmann and Econergy.

A host of new technologies and services will be on show

for Sainsbury’s, will share the company’s leading environmental strategy, with renewable energy playing a key role. His keynote session is titled “Sainsbury’s on bringing renewables into the mix: The business case for sustainability”. this year. First-time exhibitors for 2014 include premium wood pellet producer Balcas Brites and photovoltaic and wind turbine specialist Bowler Energy. The Renewable Energy Technology Alliance will also be attending for the first time and 4eco will showcase its state-of-the art energy management device immerSUN. Conference programme This year’s free conference programme will welcome more than 25 industry expert speakers in a range of seminars, panel debates and practical case studies.

The sessions will once again be chaired by Rob Holdway, director at Giraffe Innovations, a low carbon design and environment management firm.

Dr Nina Skorupska has more than 25 years’ experience in the energy industry and took the position of chief executive of the Renewable Energy Association in July 2013. Her keynote session titled “Are we on track for 2020, and what is the vision for 2030?’” will offer invaluable insight into the UK’s progress towards renewable energy targets.

Paul Crewe, head of sustainability, engineering, energy and environment,

52 August/September 2014 | water energy & environment

Practical case studies Funding initiatives, legal barriers and risk management surrounding sustainable building and microgeneration are some of the other themes set to be explored in this year’s conference.

The panel session “Get creative with your funding – knowing your investment opportunities” will invite visitors to think outside of the box in their search for investment. Speakers offering advice on funding initiatives and how to become investment ready, include Darren Riva, head of green finance for Siemens Financial Services, Miles Alexander, director of energy efficiency for the Green Investment Bank, and Gary Roscoe, a partner for TLT. The challenges posed by a multi-site renewables strategy will also be discussed in depth, with a case study by Lloyd Bentley, compliance and energy manager for the London Fire Brigade. The session will explore how the London Fire Brigade uses a range of technologies, including solar PV, solar heating, CHP and wind across multiple sites in the city.

The planning challenges and legal barriers posed by onsite microgeneration will

also be covered extensively.

Seminar speakers include Naomi Luhde-Thompson, planning advisor for Friends of the Earth, Mike Landy, head of onsite renewables for the Renewable Energy Association, and Steven McNab, a partner in environment and climate change for Simmons and Simmons.

THE RENEWABLES EVENT

The challenges and opportunities for responsible growth: a Jaguar Land Rover perspective Caroline Holman is operational carbon strategy manager, Corporate Social Responsibility, for Jaguar Land Rover will be speaking at The Renewables Event asks how you drive business growth efficiently and sustainably

T

he challenge for many businesses as they develop new products, services and operations is how to decouple growth from challenging energy and carbon reduction targets.

It is a challenge we are continuing to respond to as we increase manufacturing capacity around the world to meet growing customer demand, recognising that with this comes even greater responsibility to minimise the environmental impacts.

We constantly investigate new ways to tackle our carbon footprint as we strive towards a 30% reduction in emissions across our business by 2020 (compared to 2007).

Increased efficiency, renewable energy, alternative fuels and offsetting all offer potential to cut our emissions. We have already invested more than £10M in efficiency measures since 2010, which has reduced operational carbon emissions by over 30,000 tonnes per year. We will continue to invest not just in capital projects but in engagement and communication.

There is no single technology, approach or management tool that can deliver this. Smart energy policy is a holistic approach, as part of an overall sustainability and business strategy.

Our approach We take a lifecycle approach to reducing CO2 emissions, from supply chain, through to logistics and manufacturing, customer use and end-oflife disposal. Jaguar Land

Rover is investing in lower CO2 vehicles through more efficient engines, hybridisation, lightweighting and improved aerodynamics.

Operational carbon strategy and hence energy management sits within the Corporate Social Responsibility function and is an integral part of our global sustainability policy.

Energy efficiency encompasses many stakeholders in the wider community and environment: it is not restricted to our operations.

However all energy efficiency projects are owned and led at an operational level.

Our approach is pragmatic and simple: Use less, Buy well (energy, facilities and equipment), Renewables and Off-Setting. As a key part of our Global Social Responsibility Programme, we offset 100% of our residual manufacturing assembly CO2 emissions.

Energy management is driven by the ‘continuous improvement’ or Plan – Do – Check – Act method. However we would add another element – re-visit. Things change: technology, business and paybacks. We maintain an ‘opportunity hopper’ for all operations which includes projects and technologies which do not currently pass feasibility or hurdle rates.

Three years ago LED lighting was one such technology; reliability, validated performance, affordability and a diverse range of new and retro-fit products have now moved this to one of our most frequent investments.

54 August/September 2014 | water energy & environment

Collaboration and Knowledge sharing We do not just benchmark automotive and manufacturing sectors. The challenge of protecting finite resources is universal. Charity, food, retail, agricultural, finance and public sector bodies frequently share openly and honestly their successes and failures in terms of energy efficiency best practice.

Innovation is not just about technology but is equally applicable to engagement and funding. Green shares and co-operative funds for the wider sustainability agenda have already begun to appear and will continue to grow in availability and popularity. Integrated wealth creation and the ability to enthuse all to operate more efficiently are good for business, stakeholders and the environment.

Total Value A focus on driving out waste and optimising

energy management does not just deliver cost and carbon benefits, it also supports productivity and quality. A good example is a process lighting project in the Paint Shop at Solihull, the manufacturing site for Range Rover and Land Rover. Critical success factors included localised small-scale pilots, targeted metering and empowering ‘end users’ to select the most appropriate technology.

Results included increased lux levels (+ 36%), energy cost savings (- 50%) and improved working conditions (booth temperatures reduced by 10°C). Following project implementation, defect identification increased by 18.5%. Fewer defects mean less re-processing, which in turn lead to greater energy savings and throughput!

Growth and resource efficiency are not mutually exclusive and with a holistic and inclusive approach, can deliver far beyond the original justification. we&e

LIGHTING

Energy savings rest on six beams Lighting control using the six points described below can yield large savings, says Simon Huxtable, Osram UK lighting controls business development manager

L

ighting is a major source of power consumption, globally accounting for 19% of all energy used. Until now, reducing lighting energy consumption – and the associated bills and carbon footprint – by as much as 75% has been desirable but never seemed achievable.

It’s now time for energy, facilities and building service directors to have a consolidated view on what constitutes the best way to save energy. As a first measure, a dedicated lighting control

“

The task tuning beam limits maximum light output to reduce power consumption by 15-20%

strategy supported by a robust and intuitive lighting control system will help in minimising power wastage and, more importantly, provide a platform that is future proof for further building upgrades.

In addition to cost savings, a greater ethical commitment to environmental awareness by corporate and public organisations is driving reduction of both power consumption and carbon emissions. Adopting a lighting control strategy and installing an intelligent lighting control management system contributes directly in achieving these reductions.

Osram has developed a six-point strategy of lighting control which, when

combined with the right technology, can help unlock the maximum potential of any facility’s lighting usage, even up to 75%.

The six beams of lighting control are: 1. Smart Time Scheduling In areas of a building where occupancy control is not appropriate, time schedule switching or dimming of lights can be employed for zones as small as a room or even an individual light fixture.

2. Daylight Harvesting Through the use of photo sensors, light levels are automatically adjusted to take into account ambient natural sunlight.

3. Task Tuning Eliminates “over lighting” by setting default (maximum) light levels to suit the particular task or use of a workspace.

4. Occupancy Control Through the use of occupancy sensors, lights are automatically turned on or off or dimmed based on occupancy detection so lighting unused rooms or areas does not happen.

5. Personal Control Through the use of personal control software, individuals can control the light levels in their workspace to suit their personal preferences from their desktop.

6. Variable Load Shedding The automatic reduction of electrical demand in

56 August/September 2014 | water energy & environment

a building by shedding lighting loads dynamically (through dimming or switching) either to shave peak demand or reduce energy consumption. Load shedding can be done selectively by lowest priority areas first.

However, simply implementing or accounting for the six beams is still not enough to cut lighting bills by 75%. The trick is in the ability to custom-blend the beams to optimise savings and customise lighting performance for each user.

For example, the combination of the time scheduling and presence detection beams prevents lights staying on during the entire working day (and even during the night). The task tuning beam limits maximum light output to reduce power consumption by 15-20%.

This beam also offers a dimming buffer to guarantee minimum illumination as set by building regulations and minimise excessive operation of luminaires.

This ‘dimming buffer’ also compensates for the ageing effect that normally tends to decrease luminous flux.

Daylight harvesting and personal control strategies

fine-tune the lighting levels in any working environment to the available natural light and create a personalised working atmosphere that improves comfort and energy efficiency. Facilities managers can control this facility-wide or isolate specific zones according to the wishes of individuals using those areas.

A lighting control solution should encompass and combine the six beams for entire facilities, including multiple buildings such as university campuses.

In addition to power savings, a lighting control system can save further costs by automating diagnostics of faulty lamps and ballasts to reduce lighting system maintenance costs by eliminating manual checks.

This includes emergency lighting, which UK businesses must test and log monthly.

The right control system – one that includes the six beams – is essential for reducing the power required for lighting by up to 75%.

With this in place, lighting becomes an enhancement to buildings and no longer a drain on resources – financial or environmental. we&e osram.co.uk

School cuts lighting consumption by 38% Rye Hills School in Redcar is saving more than £500 a year on energy bills as a result of a project to upgrade its lighting with energy-efficient technology from Tamlite Lighting

R

ye Hills is a busy school in Redcar with a 900-strong student body and a clear commitment to high standards. However, until recently it also bore another, less positive tag: the school was the biggest producer of carbon in the whole of its county – responsible for more CO2 than any other local school. Understandably, finding ways to cut carbon was high on the agenda.

With budget restrictions beginning to bite, changes were also needed in order to lower maintenance needs and reduce energy bills at Rye Hills. The school’s director of facilities, Stuart Smith, was proactive about identifying

energy-efficient improvements.

These improvements ranged from building controls to variable speed drives for the air handling units, but lighting also emerged as a key area where energy could be saved.

Energy-hungry lighting “The energy-hungry, oldstyle fluorescent lights in corridors and the sports hall were left on continuously between 6.30am and 9pm, regardless of whether these spaces were occupied,” says Mr Smith. “We definitely felt it was a priority to upgrade the lighting to modern equivalents and use sensors to eliminate the old practice of lighting empty spaces.”

“We got in touch with

58 August/September 2014 | water energy & environment

Tamlite’s sales engineer, Alan Love, who came up with a lighting scheme to do exactly that,” he continues. “Originally, we had 200 fittings of 4 x 36W in the corridors, burning all the time the school was open. Using bright, modern fluorescents, we were able to reduce this to 3 x 28W fittings. And, when there’s no one occupying the space, the lighting dims to 10%.

As soon as someone enters the vicinity, it immediately ramps up to 100% again.”

Interest-free funding The school was able to secure interest-free funding for the lighting upgrades from Redcar and Cleveland Borough Council’s carbon management

fund and the governmentbacked Salix Finance scheme.

New-generation, lowenergy fluorescent lighting was installed across all of Rye Hills’ corridors and in its canteen and sports hall.

Tamlite’s TREM range of versatile recessed fluorescent modules, fitted with T8 lamps, was chosen for the corridors and canteen. Sleek and modern, the TREM luminaires provide a neat fitted appearance, with the benefit of improved energy efficiency.

In the sports hall, Tamlite’s HILUX range was installed.

Despite being a large space with a high ceiling, in the sports hall the low-profile HILUX fluorescent luminaires, fitted with T5 lamps are able

common rooms, and reception spaces, as well as outdoor areas. The upgrade will provide high-quality lighting for staff and students to create a better working and living environment. The installation of dimmer switches and a Philips LivingColors colour change lamp in every bedroom, will also allow students to personalise their lighting to suit study, relaxation or socialising.

The two-year project will be rolled out across Unite’s portfolio and will involve three joint PhilipsUnite project teams.

Richard Smith, managing director for Unite Students, said: “We are pleased to announce this partnership with Philips and our investment in LED lighting, which supports Unite Students’ commitment to providing a home for success for the students

that live with us.

“At the same time it will reduce Unite’s carbon footprint and the longer lifecycle of LED lights will significantly reduce maintenance workloads for our city teams.”

In addition to supplying the lighting itself, Philips is providing a range of services to support Unite Students in unlocking the potential that lighting can bring, both in terms of energy efficiency and ambiance. Prior to commencing the rollout across the portfolio, Philips surveyed the Unite Students properties to evaluate the existing lighting, in order to deliver the best results and recommend the most appropriate lighting solutions.

Philips will manage the installation and provide after sales service support to the Unite Students team. we&e lighting.philips.co.uk Rye Hills is no longer the county’s highest emitter of CO2 emissions

to achieve high light output at low energy consumption.

A microwave sensor was also fitted in the sports hall, so that the lights automatically switch off as soon as the last person leaves.

Carbon savings As a result of the new lighting, Rye Hills has achieved significant savings on its energy bills and maintenance costs. “We’re very happy with the new Tamlite scheme of lighting,” says Mr Smith.

“Having analysed the

energy data, I calculate that we’ve cut our lighting energy consumption within this area by 38%.

That equates to a saving of £574.80 every year. The lighting is on track to achieve payback in just five years.”

What’s more, with the help of its new lighting and other energy-saving measures, Rye Hills is no longer its county’s highest emitter of CO2 emissions: it has succeeded in driving down its carbon footprint substantially. we&e tamlite.co.uk

Top tips for LED lighting success

By Saima Shafi In a recent survey of energy managers, more than 83% of those surveyed reported that they had implemented LED lighting technology to reduce energy costs.

When asked about what they would be investing in over the next year, 80% opted for LED lighting again. These days, overworked energy managers are expected to be wizards at all types of energy saving technologies, and sometimes it’s just too hard to keep up. I thought it would be helpful to outline some tips on LED lighting to make sure your project is successful.

Compare apples with apples – make sure you are comparing lighting options using meaningful parameters.

For example, the easiest way to compare the efficiency of light is to look at the “Lumens per Watt” ratio. By using this, you can assess the brightness of one lamp against another and how much energy is used.

While lumens are important, make sure you carry out “lux level” testing to see what the current scheme is delivering. You’ll then have some values against which to measure the new LED lighting.

CIBSE guidelines for buildings is a good source to know what levels are recommended for different types of buildings.

Energy meters are very helpful to demonstrate the effectiveness of your lighting project with clear “before” and “after” consumption readings.

Don’t base your decisions on price alone. LED, like any other technology, offers many different solutions and is varied in performance. Quality of lighting should never be overlooked.

Deciding on price alone can result in the installation of inferior products and the cost of rectifying poor performance or an ineffective installation is high.

Involve stakeholders, staff and management. The best way to

get everyone behind your project is to encourage their feedback.

Agree a trial with trusted suppliers, and try before you buy.

Guarantees – while a lengthy guarantee may sound good, it may not be worth the paper it is written on. Does it cover replacement parts and/or labour?

Are you restricted to annual hourly usage and, if so, which party has the burden to prove the usage? Be clear on exactly what is covered and what isn’t.

Don’t be bamboozled by lighting jargon. If the terminology sounds too complicated then it probably is.

Ask your supplier to explain their lighting recommendations in simple terms. This will enable you to report back to all interested parties in the same way.

Work with a specialist LED supplier who understands the technology and can steer you towards the right products.

Choose a technology expert – someone who understands all the functionality you require and the objectives you need to meet.

In next month’s issue we look at “quality” in more detail and consider the subject of lighting controls. If you have any lighting-related questions for Saima to explore, please email tim@energystmedia.com Saima Shafi is co-founder of Camberley-based LED Eco Lights

LIGHTING

Waste confusion Recent changes to the categorisation of certain types of LED luminaire have the potential to cause confusion and increase the cost of their disposal at end of life. Simon Cook of Lumicom explains

T

he use of LEDs in mainstream lighting has clearly delivered significant benefits in terms of energy efficiency, carbon savings and reduced cost of ownership. However, disposal of these luminaires and light sources at the end of their life is currently presenting a challenge that could result in increased costs for building operators.

In terms of the retrofit LED lamps that are designed as a direct replacement for traditional lamps the situation is straightforward. Given that they are specifically designed to look like more familiar light sources it would be unreasonable to expect non-specialists to differentiate between the two. Therefore they are included with other lamps in Category 13 under the WEEE directive.

The problems arise with LED luminaires that have non-removable light sources, as luminaire and light source need to be disposed of together. On the grounds that LED light sources are non-hazardous the obvious solution is to include these with other types of luminaires in Category 5.

However, this isn’t the case and they are to be included in Category 13. This category also includes discharge lamps such as fluorescent, sodium and mercury light sources, which are classified as hazardous waste.

The reasoning behind this is a concern that there might otherwise be an ‘orphan waste stream’ for discharge lamps. Yet over 90% of the lamps on the business-tobusiness market are from companies that pay upfront for the disposal of these lamps. Consequently, the funding is already in place for the disposal of these lamps and there should be no risk of creating an orphan waste stream.

Crucially, this arrangement has the potential to increase disposal costs. This is because LED luminaires will be mixed with, and contaminated by, discharge lamps so that the entire batch would have to be treated as hazardous waste.

This is considerably more expensive than the cost of disposing of non-hazardous waste such as luminaires.

There is an alternative; namely having separate containers for LED luminaires

60 August/September 2014 | water energy & environment

and gas discharge lamps on site. However, there isn’t always space available on a crowded construction site and it would undoubtedly increase the risk of waste lighting products being placed in the wrong container.

There is a similar risk arising from the difficulty of differentiating between those luminaires that have removable LED lamps and those that have non-removable LEDs. This makes it highly likely that some of these luminaires will end up being categorised incorrectly.

In both of these cases, where luminaires end up in the ‘wrong’ waste stream the waste is also classed as contaminated and has to be sorted manually, again resulting in increased costs.

Lighting manufacturers are also likely to face increased costs, as any contamination breaches the conditions under which upfront payments are made to compliance schemes.

In most cases, given the long life of LED lighting, these additional costs will be imposed 5-10 years after sale and are very unlikely to have been anticipated.

In addition, the Approved

Authorised Treatment Facilities (AATFs) that carry out the waste treatment have different recycling targets for different categories of waste. For Category 5 (luminaires) the target for re-use/recycling is 50%; for Category 13 this figure is 80%.

Consequently, including any LED luminaires in Category 13 will increase overall recycling volumes, again leading to an increase in costs.

Overall then, the decision to include LED luminaires with non-removable light sources in the same category as hazardous discharge lamps seems likely to increase the cost of disposal. Clearly this could have a knock-on effect for the end-user as costs are inevitably passed up the supply chain.

For this reason Lumicom believes that including any type of LED luminaire in the same category as hazardous discharge lamps is not only confusing but also counterproductive. Apart from the cost issue it would also cause unnecessary confusion on site and increase the risk of contaminated waste entering the waste stream. lumicom.co.uk

ENERGY FINANCE

Is finance the major barrier to improved Steven Fawkes questions the perceived wisdom that finance is the number one barrier to imporoving energy use

I

t was not surprising that respondents to the Water Energy & Environment energy efficiency survey* cited finance as the number one barrier to improving energy efficiency. This has been the refrain of energy managers and consultants as long as I have been involved in energy efficiency (more than 30 years now).

What exactly does it mean and why is it still true?

An energy management programme is a machine on two levels: one for controlling energy usage day-to-day (through the use of tools such as monitoring and targeting); and one for identifying and developing a flow of viable capital projects for the organisation to invest in. If an organisation is reporting finance as a barrier, I assume it has developed more viable projects than it has approved for funding. If an organisation is not developing more projects than available finance, then lack of finance is not

really a barrier at all and in some organisations finance may be more of an excuse than reality – but let’s assume that is a small proportion of the total universe.

If an energy management programme is effective and producing more viable projects to invest in than are being approved, then the problem becomes one of how to increase the flow of funds into energy efficiency.

Capital in any organisation is always limited and there are many claims on available capital – in classic capital budgeting three principles apply: firstly “offensive” capital spending, such as new product lines or expansion of existing ones, will have priority over “defensive” spending such as cost cutting.

Secondly, all projects with an Internal Rate of Return (IRR) greater than the cost of capital should proceed (rarely achieved in real life); and thirdly, of course, the higher the IRR the better.

62 August/September 2014 | water energy & environment

“

Despite high and volatile energy costs and threats to security of supply, energy is not regarded as strategic in most organisations

Below: Finance is perceived as the biggest barrier to implementing energy efficiency projects

Energy efficiency projects often have very high IRRs (quick payback periods) but are not approved.

One barrier is the very real perception problem that costcutting is never as attractive as generating revenue – just as at home, saving is never quite as rewarding as spending!

In commercial organisations leaders tend to be promoted by generating revenue rather than by cost-cutting.

Energy efficiency also suffers from being very boring – it is seriously uncool – a hard thing to swallow for efficiency professionals.

Maximising the internal flow of capital into energy efficiency requires: • senior management to appreciate that efficiency is strategic • increased confidence that the promised results will be delivered • better projects with better business cases.

Let’s look at these in turn.

theenergyst.com

energy efficiency?

Efficiency is strategic Catherine Cooremans at the University of Zurich has highlighted that strategy is about increasing competitive advantage, which has three dimensions: perceived value of the product; costs of production; and risk.

Energy efficiency can affect all three dimensions and is therefore in fact strategic.

Despite high and volatile energy costs and threats to security of supply, energy is not regarded as strategic in most organisations. Related work at the IEA has looked at the many co-benefits of energy efficiency, which include those internal to the organisation, those in the energy supply system and those in the wider environment and society.

The IEA highlights that co-benefits such as increased productivity and increased employee engagement can be worth far more than the energy cost savings. Most business cases for energy efficiency simply look at energy cost savings and not strategic issues or co-benefits.

This tendency is heightened by the belief that energy is somehow special (the duality is that it is and it isn’t) and by energy consultants and auditors. Although I am in favour of both standards for audits (EN16247) and the new compulsory audits under the Energy Savings Opportunity Scheme (ESOS), I have a big concern that neither of these identify co-benefits or the strategic nature of efficiency and that we are in danger of undertaking another generation of energy audits that produce very little action – just like we did every decade from the 1970s.

More effort needs to go into increasing the understanding of the strategic

theenergyst.com

nature of energy efficiency – particularly amongst senior management who decide on capital allocations.

Confidence in results We need to increase confidence in the projected savings among investment decision makers.

raises the question of external finance through some form of shared savings. Although shared savings is not new – it dates back Boulton & Watt in the 1700s – its growth has been hampered by many factors including small project size, lack of trust in the results, black box business models and high costs of capital.

Large institutional investors, market intermediaries such as specialist funds, energy service companies and energy suppliers are all looking for ways to scale the market.

New models are emerging that offer the potential to turn efficiency into an outsourced service, analogous to those used in telecoms and IT. If true outsourcing models can reduce net cash flows they should be attractive. Using these models, along with protocols such as the Investor Confidence Project, should enable massive scaling up of energy efficiency investment and ultimately use of the $100 trillion bond market – opening up an effectively unlimited pool of investment funds. At that point we can finally stop citing finance as the major barrier to energy efficiency. we&e Steven Fawkes is active in energy efficiency financing and the author of “Energy Efficiency” published by Gower and the blog onlyelevenpercent.com *To see the survey visit theenergyst.com

VIEWPOINT

Engage, act, verify The UK Association of Energy Engineers is running three regional mini-conferences addressing success in energy management

A

chieving the full potential of any energy management strategy can only be realised with full senior management support, staff engagement and a robust system to measure and verify energy savings.

Three acknowledged international experts will be covering these themes in a series of interactive and practical mini-conferences organised by the UK Association of Energy Engineers. The first is planned for November in Birmingham, with subsequent repeats in York and Bristol next year John Mulholland will lead on the topic of staff engagement. He will argue that it is easy to get behaviour change strategies wrong, partly because people are more complex and less predictable than we think.

His session examines a key aspect of behaviour change: the principle of indirection or obliquity. Often we can achieve our goals faster and more effectively by adopting an indirect approach. This applies in many areas of life and particularly in the field of sustainability communications and behaviour change.

Mr Mulholland is acknowledged as a leading expert in the field of employee engagement in saving energy.

He has been involved in saving energy for 40 years, starting his career as a chemical engineer reducing energy use in large process plants.

For the past 26 years he has focused on saving energy through people and has worked for large organisations

such as BT, British Airways, Sainsburys, Carphone Warehouse, Diageo, Primark, BBC, RAF, Foreign Office, Wessex Water, Severn Trent, Universities, NHS Trusts and many Local Authorities.

John Pooley will lead a session on engaging senior management. The full potential of energy management is realised only when there is support at the highest management levels; however, often the designated energy manager is not part of the strategic management of the organisation. To address this, he or she needs to have what Mr Pooley terms “corporate organisational competence”.

In his session he will review the whys and hows of corporate engagement with energy and provide delegates with key insights to enable them to strengthen their existing programmes – or for those new to the topic – to set up an effective programme. The techniques

64 August/September 2014 | water energy & environment

explored apply equally well to environmental management as well as generic management of change.

Mr Pooley approaches this subject from the background of a chartered engineer and a certified management consultant – he trained with one of the leading global accountancy firms. He first undertook research into this area in the mid 1980s and has updated this work since then. In 2004, he was the joint author of the Managing Change guide, more than 280,000 copies of which have been issued worldwide.

His session draws on his research work and practical experience in a wide range of organisations in the UK, Europe and North America.

Vilnis Vesma, himself a former energy manager, has developed an international reputation as an authority on the analysis and reporting of energy performance data. He has chosen as his topic the

measurement and verification of energy savings, describing his talk as “the two things everyone should know about M&V”. As a certified measurement and verification professional and member of the International Performance Measurement and Verification Protocol committee, he is wellplaced to answer questions on this critical topic.

Places at these events are restricted to end users of energy only and numbers are capped at 40. This is to ensure that the group exercises will function properly. Tickets for non-members are £150 but UKAEE members enjoy a substantial discount.

For information on membership and these events email events@ukaee.org.

Basic membership is free, and despite having “engineers” in the name, it is open to anybody responsible for energy saving at work regardless of their professional background ukaee.org

The nature of the business meant that Whitbread and Powerstar had to work closely together to avoid any breakdown in service and minimise any disturbance to guests and customers of the Whitbread stable, which also includes Beefeater, Taybarn Costa and Table Table.

Whitbread has vowed to reduce its carbon footprint by 25% from its direct operations by 2017 and said the reduction in carbon emissions as a result of the Powerstar installation rollout – which is continuing across the business – was “fantastic”.

Mr George continued: “We found Powerstar to be both professional and proactive in their awareness of the installation requirements during business operational hours, which ensured minimum disturbance for our guests. We continue to invest

BUILDING CONTROLS

How to avoid stranded investments in Mike Welch, managing director of Control Network Solutions, the DALI (Digital Addressable Lighting Interface) lighting control specialist, explains why it makes commercial sense to adopt a more flexible, open approach to the control and management of lighting systems today

A

t a recent RBS Innovation Gateway meeting, Professor Doug Crawford-Brown from the Centre for Climate Change Mitigation Research at Cambridge University spoke on the concept of “stranded investments”.

A stranded investment is one where a particular technology or solution is acquired to address one set of issues. But, in the time it takes to implement the solution, the reality dawns that the situation has changed and a whole range of new issues have emerged, which will not be effectively addressed by the investment made.

This concept applies readily enough to the way we construct and manage buildings. We spend huge amounts of time, effort and money in trying to plan for a building that will operate in a certain way before the foundation holes have even been excavated.

When we arrive at the point of occupation, the world around us has

invariably moved on. Business conditions, the environment, energy prices, regulations and other factors are rarely, if ever, fixed points for any considerable length of time.

Occupier expectations of the spaces they inhabit have also changed and will constantly evolve over the lifetime of the building.

Of course, every building can be reconfigured to adapt to changing factors and user needs. But, this type of renovation often requires a fleet of trucks and an army of trades to put in new cables or remove existing ones; to move partition walls; fit new lighting fixtures and shift other equipment around. It’s a very labour-intensive and expensive process. But, it doesn’t have to be this way.

Increasingly, we live

The elitedali system allows control strategies to be re-grouped, re-zoned and re-adjusted as necessary, via a PC

in a world of soft, easily reconfigurable technologies, especially in the world of building controls. If the right technology decisions are made at the beginning of a project, then the building can be easily adapted to cope with the impact of office churn.

Take the recently completed Standard Bank office in Johannesburg, South Africa as an example. In this prestigious building everything was delivered

and installed according to specification. However, as soon as the building became occupied, reconfiguration took place very quickly.

Bank, which maximise the ability of those tasked with managing or using that space to be as flexible as possible so that they can adapt to what is in front of them at minimum cost and as near as possible in real time.

An open approach brings the opportunity to realise these and other substantial benefits. I think of it as an inverted pyramid. With the pointed end at the bottom, we emerge through the pyramid, and, as it widens out, we find greater and greater opportunity to achieve more and more desirable outcomes – flexibility of reconfiguration, energy savings, reduced CO2 emissions, better value assets, improved building ratings, easier operation and maintenance, lower costs, and so on.

By bringing together elitedali lighting control and Tridium’s NiagaraAX Framework,

energy managers can change the way the lighting operates and observe changes in energy use in real time. They can also receive in-depth and accurate information about the performance of the lighting through the BMS as never before.

Without such an open solution, it is only possible to access such data in a proprietary format, making it difficult to combine with data gathered from other areas of the building services. This approach puts that information directly into the clients’ hands, and enables them to specify the format of the information produced for “cloud analytics and big data” applications.

It is a world that liberates energy managers and buildings owners and transforms buildings from stranded investments to valued assets. we&e control-network-solutions.co.uk

Achieving large-scale reduction New technology is being used to address the challenges of estate-wide energy efficiency and create a joined-up carbon management approach, advises Chris Irwin

M

uch of what is written about carbon reduction focuses on cutting energy consumption at a single site, a single space, or even from a single source.

Yet, for larger organisations, the reality is one of multiples: multiple sites and multiple sources of energy waste.

What can be done, then, to better enable carbon reduction on a large scale, across dozens or even hundreds of sites?

68 August/September 2014 | water energy & environment

Logistics of installation Yet, for large companies like Matalan, the logistics of implementing technology like a BEMS can be offputting. Within any working environment where the floor space is continually populated by staff or customers, installing a conventional hard-wired system would inevitably disrupt trading. In order to minimise disruption, therefore, many organisations are now opting for wireless technology.

Inenco recommended that Matalan consider the WEMSystem, which is completely wireless and webenabled. WEMS has designed the system to be simple to install, and much of the configuration is done off-site in order to reduce time (and disruption) on site. WEMS technology costs about 4050% less than a conventional hard-wired system, while installation times are also reduced by about 75%.

Building the business case Conducting a trial installation should be considered an important stage of any multisite push for energy efficiency.

This can help to establish payback periods, build the business case for a technology, and allow management to see how the equipment performs when applied to a particular set of buildings.

Matalan initially trialled

the WEMSystem at five of its stores. A payback period of just six to seven months was established during this trial. This meant justification was straightforward for the technology to be rolled out across the rest of Matalan’s stores, with significant energy savings quickly achieved.

Large-scale savings “Matalan has made the commitment to install WEMSystem in all its retail outlets,” comments David Derbyshire, environmental manager at Matalan Retail.

“The installed stores have shown a considerable reduction in energy consumption of circa 18% and this is reflected in our energy bill, which has decreased dramatically since implementation. We’re continuing to work with WEMS to optimise our estate and drive further savings.”

In terms of financial return, measuring across 197 completed Matalan stores, financial savings as a result of the WEMSystem are estimated at £1,689,230 to date, while annual savings once all 206 stores are live, are projected to be in excess of £1.7m.

As the savings achieved by Matalan show, even though multi-site carbon reduction may present greater challenges, there are also greater opportunities. Large-scale energy efficiency campaigns can be daunting, yet replicating good energy practices across an entire estate can unlock not just thousands but millions of pounds’ worth of savings. we&e Chris Irwin is commercial director at WEMSinternational wems.co.uk

Sponsored column

Only months left for R22 Despite a fast approaching Europe-wide ban, reports suggest that a significant amount of refrigeration and air conditioning equipment remains operating with the refrigerant HCFC R22, so I am using this column to remind readers that such equipment is almost at the end of its serviceable life – by law, says Mike Nankivell, marketing director of the Daikin distributor Space Airconditioning plc.

The background Virtually all refrigeration, air conditioning and heat pump equipment relies on a circuit containing a quantity of refrigerant gas. Popular since the 1940s, the refrigerant gas known as HCFC R22 has been used in literally millions of applications throughout the world. It is safe and effective. However, in the 1990s it became classified as an ozone depleting substance (if leaked) and was made the subject of a phase-out programme, originally under the European Community Regulation No. 2037/2006 and recast to EC 1005/2009.

The manufacture of products designed to contain HCFC R22 was banned in Europe over a period between 1999 and 2004.

Therefore, in most cases, these have already reached the end of their normal life expectancy and are considered obsolete. Spare parts are becoming scarce and maintenance more costly but, critically, the use of HCFC R22 for any servicing and maintenance purposes is banned from 1 January 2015.

R22 – the legal position Recycled HCFC R22 can legally be sold and used until December 2014, after which the use of R22 throughout Europe is banned. As many service and maintenance procedures necessitate the removal and/or replacement of

the refrigerant, from the end of this year it may prove impossible to carry out cost-effective repairs because once removed from the equipment R22 refrigerant cannot legally be put back in. As a result, owner/operators really must consider replacing any air conditioning, heat pump and refrigeration equipment that contains HCFC R22.

Working equipment that contains R22 can still be legally operated beyond the end of this year; the ban affects the purchase and/or use of any HCFC R22 for service and maintenance purposes from 1 January 2015.

We are not scare-mongering.

We understand that in the recent recession, end-users might have been putting off the expense of replacing older R22-based refrigeration or air conditioning equipment. The fact is that if the efficient operation of such equipment is an important factor in your business then delaying its replacement is no longer a viable option.

For anyone considering just replacing the R22 refrigerant with substances offered as potential alternatives, it should be noted that these can adversely impact performance and reliability and so are not recommended by equipment manufacturers.

Free advisory service Space Airconditioning offers the services of a dedicated R22 replacement advisory team.

The team can assist with the planning process, replacement strategy and even finance packages for replacing existing systems operating with HCFC R22 refrigerant and offer advice on all environmentally acceptable, energy efficient alternatives available from Daikin’s extensive and world leading range.

Theatre gets natural Liverpool’s recently opened Everyman Theatre is using Waterloo Air Products as part of a £28 million re-build.

W

ith funding by the National Lottery from Arts Council England, the European Regional Development Fund and the Northwest Regional Development Agency the theatre’s owners Liverpool Merseyside Theatres Trust (LMTT) set about creating a modern sustainable theatre that pushed the boundaries and went far beyond the minimum requirements of current legislation.

A low carbon design and sustainable use throughout the life of the building characterised the design brief, but an air distribution system was an essential part of the design criteria to significantly improve upon the previous

ventilation system that was inadequate particularly during the summer months.

The challenging priority was to minimise running costs with sustainable design and equipment being the bedrock of the LMTT’s requirements. Natural ventilation was therefore favoured to provide a comfortable environment for both patrons and performers.

This was achieved by making full use of the building’s fully exposed concrete structure and reclaimed brickwork walls which provided excellent thermal mass and the entire front façade is designed as a large screen of moveable sunshades.

The theatre’s offices and ancillary spaces are

ventilated via opening windows and the foyers are vented using opening screens and a large light well.

Air is distributed throughout the complex which comprises a basement bistro, street cafĂŠ and box office on the ground floor.

There are three further floors with gallery seating, control room and auditorium.

Waterloo supplied Airline Linear Grilles and Louvre Faced Diffusers as well as plenums and supply and exhaust valves.

The Airline Linear Grilles not only satisfied the air diffusion requirements but met architectural specifications and aesthetics.

If an air distribution system is improperly applied

or selected, it can have an adverse effect on comfort, air quality, noise, and energy conservation. Although the selection of air diffusers and terminal devices has a lot to do with aesthetics, the theatre was keen to achieve a solution that met its objectives and delivered optimal results. “It was important that the grilles, louvres and diffusers we supplied could respond to the theatre’s air flow requirements,� says Rick Edmondson, Waterloo’s Chairman. “Our products met the high specifications whilst ensuring best value and helping the Everyman Theatre to reduce emissions and reach its sustainability objectives.� waterloo.co.uk

Geothermal rollout for Sainsbury’s Geoscart has secured backing from Macquarie and British Gas to roll out geothermal exchange technology across up to 100 Sainsbury’s stores

G

eoscart a thermal energy management specialist, has secured longterm financing to roll out its patented heat exchange technology to a greater number of commercial clients worldwide.

In one of its first projects, Geoscart will work in the UK with Sainsbury’s and utility company British Gas to provide a comprehensive groundsource heating installation and maintenance programme to reduce energy costs across up to 100 stores, starting with 15 stores this year.

Macquarie Lending has provided a financing agreement to enable UK retailers to take up Geoscart technology without having to fund the initial capital outlay.

British Gas will provide a maintenance package over the operational life of the system.

Geoscart reduces two of the largest energy uses in commercial properties by integrating cooling or refrigeration systems with

ground-source heating. It is a cost-effective, highly sustainable technology designed to cut total energy consumption typically by more than 30%. End users also benefit from minimal site disruption during the brief installation period, even in built-up areas. In addition, Geoscart users qualify for government green subsidies such as the UK Renewable Heat Incentive.

It is already widely utilised

by Sainsbury’s in the UK with 40MW installed or under contract. Geoscart already has a healthy pipeline with the planned installation of a further 100+MW of its systems to users in different sectors over the next three to four years: the decentralised renewable energy equivalent of a gas-fired power plant.

Grahame Newton, ceo of Geoscart, said: “This marks the next stage in Geoscart’s growth. We developed the baseline technology from the oil and gas sector and have successfully applied it to the

retail-consumer space. We are looking forward to rolling out the technology to a wider audience with the help of our operational partners.”

Nikolaus Woloszczuk, co-head Macquarie Lending Europe, said: “This is an exciting development in the area of distributed and renewable energy finance.

We are pleased to support the upscaling of emerging technologies that allow users to lower energy bills and minimise carbon emissions on a mass scale.”

Gab Barbaro, managing director of British Gas Business Services, said: “Energy can be a costly expense for businesses using a large amount of cooling and refrigeration equipment.

Providing customers of Geoscart technology with a comprehensive maintenance plan is one of many services we provide to help businesses effectively guarantee reduction in their energy use. Our Energy Performance Contracting business guarantees energy consumption reduction for many businesses through similar projects.”

Paul Crewe, head of Sustainability, Engineering & Energy at Sainsbury’s said: “We’re delighted to be leading the way on this groundbreaking technology – helping to reduce energy use and carbon. I hope that with Geoscart’s help we’ll now see more retailers following suit.” geoscart.com

Fuel cells can deliver An industry report highlights that fuel cell smart power units can deliver tangible benefits for 90% of UK households and small businesses

A

new report reveals how fuel cell smart power units could act like ‘mini power stations’ in more than 5.3 million UK homes, flats and small businesses by 2030.

Transferring power generation from energy suppliers into the hands of millions of customers would unlock a set of material benefits for the UK’s economy by delivering affordable, secure and clean energy locally.

The report developed by Ecuity Consulting on behalf of key UK fuel cell developers highlights that fuel cell smart power units are suitable for 90% of households and small businesses in the UK which equates to 22 million properties.

Allowing 5.3 million consumers to generate heat and electricity at home with fuel cell smart power units

would revolutionise the energy market, reducing energy bills by 21% for millions of consumers and introducing 5GW of new flexible capacity into the energy system, equal to 14 new gas fired power stations.

In addition to the direct advantages of fuel cell smart power units, the report says that this technology is also uniquely placed to become the focal point of a radical smart transformation of energy use in buildings driven by the deployment of the smart grid and the development of

intelligent products, IT tools and services.

Industry leaders have pledged to work with political stakeholders and players across the smart energy supply chain towards a plan that will assert the UK’s role as a technology pioneer and a hub for fuel cell smart power and intelligent building solutions.

Report contributors commented: “Baxi has always believed that microgeneration is the future of home heating.

We have led the European development of fuel cells and CHP solutions for residential

heating applications and recently announced our partnership with Toshiba Fuel Cell Power Systems Corporation, a global market leader in the development, production and marketing of PEM fuel cell systems. The publication of this report comes at a crucial time for the fuel cell industry. Baxi will work closely with the heating industry and political stakeholders to advocate for cleaner, decentralised energy in order to make this a reality for homes in the near future.” – David Shaw, Business Development Manager, Baxi Commercial The report Fuel cells the smart power revolution is available at ecuity.com The report was commissioned

National Gallery improves heating Hoval has been aiding the National Gallery in supporting critical environmental control and energy savings

H

igh efficiency boilers from Hoval are helping the National Gallery in London reduce its energy consumption and carbon footprint, while maintaining a stable internal environment for the exhibits.

The National Gallery opened in 1838, occupying a dominant position in Trafalgar Square at the very centre of London. The original building has been extended several times since then and now houses the national collection of paintings in the Western European tradition from the 13th to the 19th centuries.

The National Gallery has a strong commitment to sustainability, with ongoing initiatives to improve energy

efficiency and reduce carbon emissions. In support of this policy, a decision was made to replace the existing boiler plant and consulting engineers hurleypalmerflatt were commissioned to design a more efficient solution.

Nigel Back of hurleypalmerflatt explained: “The base heat loads at the National Gallery are met by a combined heat and power (CHP) unit but the existing back-up boilers were oversized for meeting the additional heat loads, resulting in inefficiencies. We therefore designed a system that would be more efficient and responsive, while also providing the resilience required to maintain the

76 August/September 2014 | water energy & environment

critical internal environment. “Having reviewed a number of manufacturers, we specified Hoval as providing the optimum combination of efficiency, reliability and best value,� he continued.

The new system, installed by contractors Capri Mechanical, uses two UltraGas condensing boilers as lead boilers, supplementing the CHP plant at times of peak demand. Using a pre-mix

modulating burner with up to 12:1 turndown, the UltraGas boilers are able to respond efficiently to variable heat demand while taking advantage of condensing opportunities for even higher efficiency when return water temperatures permit.

In addition, three dualfuel SR-plus boilers have been installed to ensure that heating can be maintained to protect exhibits in the event of interruption to the gas supply.

In parallel, the heating system has been reconfigured, replacing the existing single circuit system with a primary circuit and several secondary circuits to provide better control. we&e hoval.co.uk

THE WATER EVENT

Event announces 2014 programme Now in its second year, The Water Event is set to deliver unrivalled content, exhibiting and networking opportunities when the show opens its doors from 16 to 17 September at the NEC Birmingham

A

s the UK’s first dedicated event for water efficiency and management, The Water Event addresses the growing need for water conservation and offers expert advice to businesses as deregulation approaches.

Aimed at large-scale businesses and public sector organisations seeking to improve their water efficiency and management, the event is free to attend and, again, will be co-located with The Energy Event, The Renewables Event and RWM 2014 in partnership with CIWM. The Water Event Theatre With competition in the water industry only three years away, UK water companies are now looking at how they will adapt to the forthcoming open market. The Water Theatre offers more than 15 free CPD-accredited sessions from government advisors, industry leaders and academics. These sessions will provide updates on upcoming legislative changes around water procurement and case studies on how industry-leading end users have reduced their water consumption, changed behaviour and substantially cut water bills.

Dieter Helm will be speaking in the conference on the future of water regulation and finance and what happens next after the periodic reviews.

Ofwat senior director for customer and casework Richard Khaldi will also speak. In his talk, Mr Khaldi will focus on understanding how customers’ trust and

a leak detection company to survey the water mains and identify any potential losses.

Even though the leak detection company was able to access the ZSL AMR data loggers for historical water profiles, their success was limited and proved relatively expensive, possibly due to the expansive nature of the site.

ZSL immediately realised that as an ongoing project it would not be financially viable to outsource total responsibility for leak detection to an independent company.

The strategy therefore needed modifying to attain better value for money. So along with a nominated person from the maintenance department, the site was broken down and mapped out into zones. This enabled ZSL to investigate the water use within a given zone and area by way of step testing.

The historical data is a reminder of what has been achieved.

he Zoological Society of London (ZSL) took the initial step in streamlining its water management in 1995 when AMR data loggers were introduced to monitor site usage. Since then ZSL has saved more than £1m on water, with the majority of these savings being generated since 2002.

Today ZSL’s water bill is only 5.93% higher than it was in 2002. From 2002 to 2014 the m³ mean cost of water charged by the local water company to ZSL has increased by more than 106%.

A water management lead (WML) position was created in response to the 1995 drought.

The brief was to define strategy, operational planning, budgeting and measuring efficiency for water supply and wastewater initiatives.

The time allocated to the role was one to two days a week.

The starting point was the installation of the AMR data loggers followed by the implementation of the basic and inexpensive water saving solutions. The WML directly reports to the energy manager, monthly usage reports and historical data are assessed and any anomalies of water usage highlighted. From these reports strategies and future targets are set (one to five years).

Assessing water leakage is always the natural starting point. The infrastructure at ZSL had in excess of 2000 metres of old cast iron water mains and covered a site of 36 acres. Initially the task seemed a little daunting. The decision was taken to contract

T

he Yooz business was started as an innovative project in April 2009. In the first five years of operation, it has grown from start-up to a £1m turnover selling waste building materials and office furniture.

Based initially in an open yard, neither mains water nor mains electricity were available. And then the two following winters were among the coldest on record, with deep snow and ice. It did teach us about resilience.

Indeed the weather has been so bad in the winters that strong gales led to us selling our entire stock of timber for fence repairs, and we now also buy in locally sourced timber to supplement our stocks.

A solution?

The west of Scotland is blessed with reasonable rainfall, so we diverted the rainwater from the roof downpipes into intermediate bulk containers.

These cheap tanks were linked together by recovered waste

structure we used a large domestic cold water storage tank to store the pumped water to gravity feed the toilets and wash hand basins. This was still just rainwater and unsuitable to drink, so we bought in bottled water until we sourced a filtration unit that would be cheap to run but able to provide drinking water and washing water.

We have 12 staff onsite and five volunteers each

day, together with young long-term unemployed and disabled trainees (90 people have been given skills and work experience in the past year alone) so the cost of bottled water was becoming prohibitive.

A search of the internet for suppliers of water treatment plants in Scotland found Bob Garrow of RS Garrow who was trialling the use of the Aqualogix system from Germany.

Simply put, the equipment did what it said on the tin – providing the ability to give us 800 litres of purified drinking water an hour.

Beyond drinking water and water for hand-washing, we also use it in cleaning office furniture upholster, keeping our fleet of 13 vehicles topped up with water and providing water for the cleaning of our old warehouse.

was a false economy.

The equipment arrived, plumbed in easily and cheaply by ourselves, and commissioned by the engineer, all for a price that wouldn’t buy a fiveyear-old Ford Transit!

The result is we have adequate rainwater stored for our needs, which is cleaned and purified as we need it (so no need for sanitised storage tanks), and pay for itself within 30 months. And if we move, the equipment is easily moved with us.

WATER MANAGEMENT

Wastage enhances water and energy efficiency The use of water in energy production is rising up the agenda. But there’s another side to the ‘water energy nexus’ that arguably has a greater impact, namely the energy needed to pump, clean and transport water to businesses and homes or ‘energy for water’, writes Itron’s solutions delivery manager Rob De Nijs

S

aving energy saves water, and vice versa. Just as energy efficiency and smart grid initiatives are being commonly adopted to address energy efficiency, similar solutions to the problem of water efficiency are rising in importance.

The underlying process of obtaining clean water reveals the complexity of a much larger problem.

In particular, the costs associated with treating, pumping and distributing water to consumers make water utilities some of the highest energy users in the commercial sector. As such, any leakage equates to money and time that is lost and can never be recouped by utilities.

For the UK, water leakage can amount to millions of pounds wasted and considerable, unnecessary CO2 emissions. For example, in England and Wales in 2010-11, 2,559 mega litres of water (the

equivalent of 1 million litres) were lost per day through leaky pipes.

Pressure from government and Ofwat to reduce leaks is making non-revenue water (NRW) a major target for utilities. On average, these rates are around 21% of their overall water usage, with leakage making up a significant proportion of this total. To rectify this problem, smart metering technology is absolutely vital as it can accurately identify leakage and therefore save money.

To this end, there are three main approaches that can be taken in resolving issues with NRW, to the benefit of the water energy nexus.

Metered leak detection At the very end of the network often around consumers’ homes, small leaks can appear that permanently waste water; which

neither the consumer or utility is aware of. Installing a meter that can flag abnormal consumption is the first step to measuring and managing water use. More advanced meters and networks can provide more accurate data such as the date and time

“

The costs associated with treating, pumping and distributing water make water utilities some of the highest energy users in the commercial sector

when the leak started and the volume of water that has escaped. All this information can be collected and fed back to the utility company so that billing issues can be resolved quickly.

District meter networks This next method can also present significant savings to utilities. By installing a master meter of utilities’ overall in a location usage is from nonthat feeds a revenue water particular area or district and identifying all the premises that it feeds, utilities companies can look at the total consumption of the district and identify any discrepancies which may indicate NRW leakage. By finding anomalies in data, utilities companies can much more easily deliver fairer billing and save money at the same time.

21%

86 August/September 2014 | water energy & environment

Acoustic leakage detection Finally, acoustic leak detection is another way utilities can account for and identify NRW as a part of their water conservation programmes.

Using a communication module with an integrated acoustic leak sensor, water

utilities can collect and analyse vibration patterns from anywhere in the distribution system, significantly improving their ability to detect leakages early thereby conserving precious water resources.

Leakage reduction in the UK is imposed on utilities using the sustainable economic level of leakage (SELL) framework and is of paramount importance in water stressed areas such as the South East since alternative supplies are difficult to come by. Although infrastructure upgrades can be a costly procedure, smart metering projects have many added benefits besides improving leakage reduction, such as accurate billing, customer service improvements and improved demand forecasting.

Once implemented, they provide data to utilities so they can focus on conservation and creating a sustainable future for their customers and their business. we&e itron.com

Leak detection yields big savings £27,375 annual savings have been identified by detecting a water leak at the Loughborough site of Leicestershire Fire and Rescue Service

T

he detection of a continuous 30m3 per day water leak

by Energy Metering Technology’s Databird aM&T (Automatic Monitoring and Targeting) system has saved taxpayers approximately £75 per day, equating to an annual saving of around £27,375.

Leicestershire Fire and Rescue Service have employed Databird aM&T technology throughout their 20 Fire and Rescue Stations. This major leak was detected

at Loughborough Fire and Rescue Station. The rectification of this leak has prevented large scale water damage, wastage of large volumes of water and of

course money. The figure below shows the water consumption comparison during the leak period and after the leak is repaired.

Databird interfaces with any utility meter to monitor the consumption remotely and will raise an alarm should the consumption exceed pre-set parameters.

Databird is a multi-utility aM&T System, with regards to water it is certified by Defra (Department for Environment Food and Rural Affairs) as

leakage detection equipment.

WATER MANAGEMENT

Developing sustainable drainage Atmos Consulting’s technical director of eco-hydrology Richard Steel discusses about how to get SUDs right for the prevention of future flooding in the UK

T

he logic behind compulsory sustainable drainage systems is clear: past generations of drainage engineers adopted the approach of trying to dispose of surface drainage as quickly as possible with rapid discharges to receiving river channels, which cannot cope with the volumes.

These channels have often been constrained through engineering and building works with resultant loss of the functional river flood plains, which could provide natural attenuation storage for floodwaters.

The implementation of wide-scale developmentdriven SUDS can obviously cumulatively contribute to reducing flood problems, but we are a long way from a long-term solution. To tackle future flooding, particularly given increased rainfall predictions, requires more extensive measures to be

“

We need a shift in emphasis from building barriers to flood water to creating connected wetlands

established across and within river catchments, both to provide temporary storage of water and to reduce runoff rates in the first place.

There are various approaches that can be adopted to achieve this goal, but all require political will and good coordination between the government, local authorities, statutory organisations, technical specialists and landowners.

Such measures may include re-establishment of woodland to reduce catchment runoff rates, or reconnection to areas of fragmented upstream floodplain

Flood defences: there is a clear need for new strategies in the UK

88 August/September 2014 | water energy & environment

to provide floodwater attenuation areas to protect downstream urban areas.

This will have economic implications as many areas where such measures would need to be implemented are currently used for agriculture.

Compensatory funding would be necessary to offset these potential losses to farmers. It may even be better in the long-term to develop a policy to purchase these areas of land specifically for flood protection purposes and engage the local communities and wildlife organisations to further develop them as ecological and conservation areas.

Landowners could receive long-term compensation payment for assisting in any routine maintenance works under an “Ecosystem Services” funding scheme for this multi-functional green infrastructure.

Maximising the ecological diversity and productivity

within these areas would require the hydraulic regime of the reclaimed floodplain to mimic as far as possible the natural processes of seasonal flooding and drying. So reclaiming and reconnecting areas of undeveloped floodplain, combined with other upstream catchment management measures, may not only contribute to reducing the potential for flooding downstream but may also provide significant ecological benefits to both the watercourse and its borders and banks.

Maximising the ecological quality or potential of the UK rivers is also the key objective of the Water Framework Directive (WFD), the European legislative framework under which the “performance” of UK rivers is monitored and managed. So a large-scale SUDS approach may also assist in helping UK rivers meet their principle WFD objectives.

We need a shift in emphasis from building barriers to flood water to creating connected wetlands to act as large-scale natural SUDs to soak up the excess water and allow it to drain back to the river at a slower rate. Yes, there will be substantial legislative, engineering, economic and political hurdles that need to be overcome, but given the climate change predictions and the increasing problems and economic impacts already being caused by excessive rainfall events across the UK, the time for implementing new flood strategy approaches in the UK is surely already upon us. atmosconsulting.com

WATER MANAGEMENT

Going in hard Sustainable drainage systems have an important role to play in reducing the risk of flooding. Stuart Crisp, business development director of the Concrete Pipeline Systems Association , argues that the many costeffective designs will be based on a combination of soft landscapes and hard manufactured solutions

A

development of 105 houses in quiet commuter village nestled in Charnwood Forest is the unlikely setting for an innovative approach to drainage design. However, at the Markfield development in Leicestershire, specialist sustainable drainage systems (SuDS) consultant Edwards and Edwards has developed a drainage solution that cleverly blends above-ground natural features and below-ground precast concrete water storage solutions to maximise the area available for development.

This combination of aboveand below-ground water storage solutions has enabled developer Jelson to manage surface water run-off within the site while providing the wider benefits of amenity and ecology in a costeffective solution. Schemes with similar combinations of above- and below-ground features will start to become commonplace when Schedule

3 of the 2010 Flood and Water Management Act comes into effect in England and Wales.

The Act was drawn up in response to the Pitt review, which set out to examine ways to reduce the risk of flooding and to find ways to minimise the impact of any floods that may occur following the floods of 2007, in which 13 people died and 55 000 properties were damaged. It will require developments to install SDS solutions.

The principle behind a SuDS scheme is that it is designed to mimic the natural drainage characteristics of the land by dealing with rain where it falls, as far as is practicable. It is expected that initially all new developments of two properties or more will be required to install a SuDS solution and it will become a duty on Local Authorities to approve, adopt and maintain the drainage system through SuDS Approving Bodies (SABs).

SuDS include above-ground

90 August/September 2014 | water energy & environment

A combination of buried oversize precast concrete pipes and box culverts were used

“soft” landscaped features such as swales, detention ponds and filter strips and below-ground “hard” solutions such as concrete soakaways and attenuation tanks. There is no typical or standard SuDS solution; every site needs to be assessed based on its specific attributes. However, many comprehensive and cost-effective solutions are likely to include a combination of above and below-ground features.

Going underground When Edwards and Edwards set out to develop a solution for the Markfield site, its initial designs favoured above-ground water retention, including a large dry balancing pond.

However, it soon became clear that by moving a significant proportion of the storage underground more of the site could be freed for development.

At Markfield, a combination of buried oversize precast concrete pipes and box culverts from CPSA member company FP McCann were

used to provide the runoff attenuation to the site’s upper catchment area. The site’s lower catchment area is controlled using a series of flow control chambers before the water is released, via headwalls, into smaller natural SuDS features comprising swales and a permanently wet micro-pool providing a natural feature on the scheme.

In addition to flood management, the implementation of SuDS is also about improving water quality. A well-designed SuDS scheme will simulate the many natural processes that take place to remove pollutants from surface water.

Slowing down the conveyance of water, for example, is a simple mechanism that enables sediments containing pollutants to settle out so that they can be captured and routinely removed from the system.

At the Markfield development, Edwards and Edwards is working with Leicestershire County Council Highways Division to trial the design of a precast

theenergyst.com

concrete filter treatment chamber, which has been designed to be situated under driveways. The unit incorporates an innovative filter to remove hydro-carbons, heavy metals and sediment before the run-off is released into balancing ponds where micro-organisms will remove nutrients and pesticides from the surface water.

SAB approval The introduction of Schedule 3 of the 2010 Flood and Water Management Act has been repeatedly delayed by Defra; it is not now expected to be introduced in England and Wales until spring 2015 at the earliest (SuDS is already compulsory in Scotland).

When the Act does finally comes into effect, it is becoming increasingly clear that proprietary, manufactured precast concrete systems will have an important role in providing cost-effective water management options in combination with aboveground SuDS features.

Whatever combination of SuDS features is included in a scheme, planning permission will not be granted without SAB approval of the SuDS design.

In general SABs will sit within county councils or unitary authorities. On completion of a development the SuDS scheme will, in the majority of cases, be automatically adopted by the SAB authority. As a result, in addition to being in charge of a substantial asset, ultimate responsibility for the on-going maintenance will also fall to the SAB authority, which means that it will be their responsibility to ensure that the SuDS assets continue to perform satisfactorily over the lifetime of the development.

Adopting bodies will, therefore, need to be aware of the impact of material choice on the value of an

theenergyst.com

adopted asset and its ongoing maintenance or even replacement cost over a development’s life. They may also need assurance that the features and products used for rainwater collection, attenuation, treatment and conveyance are capable of providing a long-term solution – choices made today can reduce the risk of problems occurring at a later date.

From the asset holder’s perspective the use of traditional systems, such as precast concrete hard landscaping elements, should provide assurance of the capability of the SuDS components’ long-term operation because there exists a vast amount of industry experience and knowledge in their operation. Water companies, for example, are familiar with the operation and management of sewer assets over many decades.

The water company Seven Trent Water adopted the system at Markfield.

Leicestershire County Council has a policy of not adopting large-format water storage pipes. The precast concrete pipes and box culverts are designed to allow for water to be carried at the base in dry weather flow channels during normal flow periods.

However, during periods of intense rainfall, a vortex flow control unit installed in the pipeline enables water to be attenuated to a controlled discharge rate and backed up for storage. This dual functionality enabled the pipes to be adopted by the water company under the Section 104 agreement.

To help users gain maximum long-term benefit from proprietary precast concrete components, the CPSA has produced a free CPD, entitled Surface Water Management using Proprietary Precast Concrete SuDS Systems. we&e concretepipes.co.uk

The greywater is rising A greywater reuse system is reducing the mains water needs of buildings by up to 30%

B

usinesses are increasingly turning to water recycling technology to reduce their water bills and lessen their environmental impact.

That’s according to Reaqua Systems, specialist in the collection of waste-water (greywater) from sinks, baths and showers recycled for use in flushing toilets.

Suitable for retrofit as well as new build and designed for use in residential, commercial and municipal properties, the greywater reuse system reduces the mains water needs of a building by up to 30%.

A revised plumbing set up takes all waste water from baths and showers, redirecting it through a filtration unit where it is automatically treated with a disinfectant.

This treated water is collected in a tank and pumped on, as required, to supply all the flushing water needs for multiple toilets in a building.

Award-winning architectural practice David Morley Architects is among an increasing number of businesses to fit the technology in its commercial premises. Camilla Morley, the practice’s environmental development consultant, said: “Our demand for hot water has increased over the past three years as we have been encouraging a cycle to work policy, supported by additional new in-office showering facilities for our staff. As a company which keeps abreast of progress in sustainable development in all areas of our work, we felt it was both economically and environmentally sensible to fit this technology and an opportunity to set a positive example to our clients.

“The reAqua system reduces our water consumption by

up to 30% by recycling the shower water on the first floor to flush the two downstairs toilets, supporting our ‘more with less’ approach to design.”

Reaqua Systems CEO Stephen Bates said: “As most buildings in the UK have only one water supply, we have, until now, had little option but to put up with the confused logic of using drinking quality water to flush toilets. The costs associated with the water treatment process, both financially and environmentally in terms of the energy used, are significant and greywater reuse technology represents an immediate and simple way to reduce water demand across the UK. “With more and more employees cycling to work, and requiring a shower when they arrive, we’re seeing increasing numbers of businesses turning to this technology.”

An optional feature of the Reaqua System ingeniously allows heat to be extracted from the building’s greywater, before it’s recycled, so it can be fed back into the central heating system. The reAqua+ fits a heat exchanger to the grey water reuse link between the bath, shower and toilet flush and recaptures around 50% of the heat energy from the bathing water, feeding it back into the building’s hot water system reducing fuel bills as well as enabling a two-fold reduction in CO2 emissions.

Research has shown that using low-flush toilets may not provide sufficient movement in small pipes to carry away solids, leading to blockages and flooding, and additional evidence suggests that these devices may act as a false economy with users running low flow showers for longer in order to improve their experience. we&e reaquasystems.com

PUMPS & VALVES

Solar-powered pumping A new product launched by NOV Mono offers an effective solution for pumping water on small-scale farms and off-grid properties

T

he SUN-BUDDY is a solar-powered submersible pumping system that has been designed to combine high performance, long life and minimal maintenance requirements.

Managing water movement on a small rural property can be a challenging task, with water that has to be drawn from rivers, bores, tanks and

stock dams for small-scale crop irrigation, stock watering, garden watering and general use. The Mono SUN-BUDDY uses technology that was previously only available to large-scale agricultural operations, and offers a versatile variable flow capability which is suited to a wide range of different applications.

Driven by solar energy, this small but efficient pump

requires no diesel, grid power, wind or batteries to run.

This enables the operator to quickly recover the initial cost by eliminating all future fuel and electricity bills.

Mono’s agricultural industry manager, Nick McNamara says: “It uses a progressing cavity action with a helical rotor element which allows it to deliver maximum output, even if the water contains silt or iron oxides. A variable speed control allows the flow to be regulated to suit different conditions such as low yield bores, while a low speed operation capability provides extended rotor and stator life.�

Designed to operate in harsh conditions, the SUNBUDDY incorporates a robust, brushless, submersible DC motor. This delivers high torque, high efficiency performance and features thermal overload protection that ensures long life and

Pump efficiency hit by magnetite build-up Circulator pumps fitted with permanent magnet motors are at increased risk of magnetite build-up, which is badly affecting both pump and central heating system efficiency.

The warning, from Xylem, comes in the wake of increased concerns that modern circulators are at risk of magnetite build-up that can affect system efficiency by between 10% and 50% in extreme cases. This increased power consumption does not meet the requirements set out under the ErP 2009/125/

EC directive, which is the driving force behind the increase in the use of high efficiency circulators.

Magnetite, also known as “black sludge�, is dissolved metal caused by the natural erosion of radiators and other heating system components, which is held in the water running through a heating or hot water system.

According to Xylem, the problems stem from the fact that the majority of modern high-efficiency circulator pumps are equipped with a permanent magnet motor

92 August/September 2014 | water energy & environment

which attracts the magnetite where a magnetic field is present and reduces motor efficiency unless, as part of the pump design, the flow of water is separated from permanent magnetic parts.

Chiara Musola, AWS global product manager circulators at Xylem commented: “To combat this problem, we would recommend

the flushing of the system together with an inhibiter and a magnetic dirt separator. In addition, circulator pumps fitted with ‘anti-block technology’ have the capability to separate the main flow of the transferred liquid from the permanent magnetic parts, meaning the pump will never be susceptible to blockages from magnetite or sludge.� lowara.com

DRIVES & MOTORS

Greater speed and torque control Direct torque control – used extensively in ABB’s variable-speed drives since 1996 – has been improved to bring higher accuracy in motor speed and torque control, as well as the ability to control more motor types

A

BB’s fourthgeneration direct torque control (DTC) provides enhanced performance in open and closed loop and a higher switching frequency, says the company. Speed and torque control accuracy have been improved for both dynamic and static values.

Support for high-speed motors up to 500Hz (as standard) and absolute encoder and resolver support are provided, while other improvements include more choice of identification (ID) set-up runs. These include highly accurate standstill ID runs, allowing the drive to identify the motor from its performance characteristics without the need to uncouple the motor from the load.

Drives equipped with the new DTC can now respond to changes in the customer speed reference much more quickly, with the motor shaft responding within 2ms of a reference change instead of 10ms.

DTC lets users of the latest ABB industrial drives, ACS880, control any motor type without a change to the firmware, making it practical to use squirrel cage, permanent magnet and ABB’s advanced synchronous reluctance (SynRM) motors – its latest motor control technology offering high efficiency IE4 or high output compact motor variants.

This widens the scope for engineers to use almost any motor to suit their needs.

The ACS880 drive offers fully functioning scalar control with its own ramps,

theenergyst.com

DTC was developed to bring the best motor control of induction motors and is now extended to control other motor platforms

fixed and skip speeds. Scalar is useful in multi-motor applications and can be used to test installations before switching to DTC; particularly useful when the test motor is not the same size as the motor to be used on site.

With DTC, field orientation is achieved without feedback, using advanced motor theory to calculate the motor torque.

DTC uses fast digital signal processing hardware and an advanced mathematical understanding of how a motor works. The result is claimed to be a drive with a torque response that is typically 10 times faster than any AC or DC drive. This gives improved process control and a more consistent product quality.

The dynamic speed accuracy of DTC drives will be eight times better than

“

A further feature of DTC is flux optimisation (or energy optimisation), which provides enhanced energy saving beyond that of other VSDs

any open loop AC drives and comparable to a DC drive that is using feedback.

Some applications require particular feedback devices, for either position or speed feedback. Although DTC negates the need for speed feedback devices, accuracy can be further improved with an extensive range of encoders, resolvers and tachometers.

The ACS880 drives have option slots to allow these items to be fitted internally, making installation convenient and cheaper.

DTC was developed to bring the best motor control of induction motors and is now extended to control other industrial motor platforms, being one of the few to generate full torque at zero speed on standard induction motors.

It can be applied to high dynamic or highly arduous applications and can tackle most industrial applications.

A direct-on-line (DOL) or soft start control will abruptly bring the motor to rest, with the danger that the load or the coupling is damaged. By contrast, the DTC flying start smoothly catches the load and takes it under control, returning it to the desired speed.

A further feature of DTC is flux optimisation (or energy optimisation), which provides enhanced energy saving even beyond that of other variablespeed drives. It adjusts the motor flux to the optimal value for the load conditions at the time, thus constantly saving energy across the lifetime of the application. we&e abb.co.uk

Top Marks for Delmatic’s system at the University of Greenwich Delmatic is supplying a comprehensive DALI lighting management system for the University of Greenwich’s new School of Architecture, Design & Construction. The system enables individual addressing, switching, dimming and monitoring of DALI luminaires, in conjunction with presence-related and daylight-linked control of lighting groups from DALI presence detectors and multisensors.

The 16,500m2 Stockwell Street development comprises two linked buildings arranged in a ‘finger’ layout with internal courtyards allowing daylight and natural ventilation into the spaces.

The buildings are designed to achieve high standards of sustainability to meet the criteria of BREEAM ‘Excellent’ and incorporate elements such as energy-efficient systems, solar panels, and “living roofs”, where wildflowers and other plants will create a wildlife haven at the heart of Greenwich town centre, within a UNESCO World Heritage Site.

The control of the lighting will play a key role in meeting the strict energy efficiency targets. Lighting is controlled throughout the building, using different control strategies in different areas. Many of these areas use suspended luminaires, with Delmatic’s DALI buswire modules enabling individual addressing, switching and dimming of the luminaires via a common Dali buswire.

DALI multisensors and presence detectors are installed throughout the building, many of them mounted within the suspended luminaires, to provide presence-related control and dimming in relation to daylight levels at the perimeters of the building. Solenoid water valves in the toilets are switched via a Delmatic DALI One Relay which relates water use to occupancy of toilets. www.delmatic.com

Direct connect meter Elster Solutions has launched the A1160 160 Amp Direct Connect electronic polyphase electricity meter. The new meter has both ISO 9001 and SANAS 17025 accreditation.

Saving time and money is crucial for utilities. Because the A1160 is a direct connect meter, no current transformers and ancillaries are required, and installation time is reduced. Furthermore, the new meter has impulse protection at twice the international standards, so it is fully protected against hazards, including lightning interference, which increases the overall life of the meter.

An extended list of functionalities allows the use of the A1160 in many customer installations and configurations. As a multi-function four-quadrant meter, the A1160 provides extensive measurement, instrumentation, load profiling, time of use, maximum demand, security monitoring and historical data recording. The meter can operate as stand-alone or as part of a comprehensive AMR/AMI metering system through a variety of state of the art communication modules, up to 100 kilovolt-amperes (KVA) installations.

Bioenergy plant design – decisions for tanks As energy prices continue rise, the number of bioenergy plants across the world is increasing rapidly. However, design engineers are faced with a number of basic choices when it comes to starting a new project. One of the major decisions is the construction material to be used in the tank design of the digester, gas storage and feedstock storage.

Essentially, three materials dominate the market, concrete, carbon steel and stainless steel, with the steel variants having a variety of coatings and construction techniques to choose from as well. The final decision for any project should be made from an informed standpoint to ensure that the most appropriate design is employed in order to deliver a reliable and durable solution.

Anaerobic digestion plants can be designed to operate in a number of ways, depending on the scale of the plant, the feedstock to be used and the aims of the project itself in terms of energy output. Clearly these must be assessed and determined first, before considering the best suited tank design and construction method. The essential aspects of each choice are detailed below: As a building material, concrete has two major advantages, it is strong and relatively cheap and as such it has been used for the construction of bulk storage tanks for some time. However, the process of anaerobic digestion requires much greater resistance to chemical attack than that provided by concrete. The substrates and gases involved in the processes can lead to a reduction in the expected lifespan of the tank. In addition, the standard surface finish of a concrete tank inhibits the agitation process used within the AD process.

Another consideration at the design phase of any project is the overall build time which affects the total project cost as well as the timeframe before the plant can generate income. The construction of a concrete storage facility can either be completed using prefabricated panels, lifted into position by mobile crane, or by pumping liquid concrete into a ring of preformed sections. These methods can require increased periods of time to complete and use a number of large, heavy plant vehicles. lipp-system.co.uk

Q&A

Andrew Maclagan The managing director of Baxi Commercial talks about Aston Martins, James Bond and being the last King of Scotland

W

ho would you least like to share a lift with?

Jeremy Vine.

It would be all too easy to end up having an inane debate on a straightforward topic – just listen to his lunchtime radio show!

You’re God for the day. What’s the first thing you do?

Stop the war in the West Bank. I’m neither religious nor political but that conflict just makes me despair.

If you could travel back in time to a period in history, what would it be and why?

I’d go back to 1305 when William Wallace was fighting his last battles. I think his position in history has been overstated and it would be interesting to see the truth. Mind you, I’d want to ensure there was a way back to the present day first.

Who or what are you enjoying listening to? (music, radio etc) Music of the moment ranges from INXS (showing my age) to Kings of Leon.

What would your super power be and why?

Mr Invisible – you could get up to all sorts with that power.

What would you do with a million pounds?

Less than I should be able to, an Aston Martin sounds quite appealing though.

Whatever’s in the car really, which goes on when Jeremy Vine’s show starts!

What unsolved mystery would you like the answers to?

What created the gas that created the Big Bang? If you stop and think about where we all came from it gets a bit deep.

What would you take to a desert island and why? (excluding loved ones and practical things) Tea bags, pan to boil water, milk, and mug – I can’t do without a good cup of tea.

What’s your favourite film?

My favourite film would be something like The Rock.

I like films with lots of shooting and cheesy one liners.

My favourite book is Shantaram – a very gritty book about life in the Indian underworld.

If you could perpetuate a myth about yourself, what would it be?

That I was The last King of Scotland!

98 August/September 2014 | water energy & environment

What’s your greatest extravagance?

My James Bond collection of books, scripts and signed photos.

If you were blessed with any talent, what would your dream job be and why?

Professional golfer, I’ve played since I was four and just don’t get enough time to do the one sport I truly love.

What is the best piece of advice you’ve ever been given?

Tell the truth, lies always catch up with you.

What irritates you the most?

Politicians not answering the question.

What should energy users be doing to help themselves in the current climate?

Install a high-efficiency Andrews Water Heater, Potterton Commercial Boiler or Sener-tec CHP unit. They can all help save money on your fuel bills and benefit the environment at the same time.

What’s the best thing – work wise – that you did recently?

Accept my new job as MD of Baxi Commercial – a great business with huge potential. we&e

ENERGY MARKET ANALYSIS

Market report water energy & environment’s regular section brings you an eight-week overview of the latest analysis of the power and gas markets from Energy Trader Daily. By Serge Mazodila

T

he market proceeds closer to the winter trading period of 2014, having traversed what was a “complacent summer trading period”. Gas prices have so far found a floor on the back of the July trading month, having fallen for two straight months before the technicals came in to support the NBP market.

The fundamentally Bearish picture of the summer 2014 trading period has been clouded by a combination of impending winter weathers, geopolitical worries out of Europe and the Middle-East; this has greatly contributed to market volatility as the bubbling tensions between Ukraine and Russia return to the centre stage of risk pricing.

Although Russian natural gas continues to transit through the Eastern-European state of Ukraine to Western Europe, the uncertainty surrounding these flows leading to a winter trading season (traditionally dominated by cold weather)

has brought back a higher level of volatility in the gas market, particularly amongst prompt contracts. This state of affairs looks set to continue in the near-term, as the two countries tussle over payment, pricing, and pride.

The geopolitical volatility, emitted out of Eastern Europe, has also had an adverse impact on the wholesale electricity market, which takes it cue from the gas market prices. With gas prices looking buoyant ahead of winter, the

supply issues from gas flows through Ukraine to Western Europe, has led to some upward pressure in the power market since prices levelled-off in July, following the abrupt sell-off of May and June 2014.

The power market, which tends to be more subdued, has exploded to the upside going into the month of August, thanks to the technical buying, geopolitical issues, and supply margins reductions caused by unplanned nuclear outages.

The higher gas price have

encouraged further gains in the electricity market during the second half of summer (Qtr3’14), positioning the wholesale market for further gains as the recent summer complacency begins to face geopolitical issues and late minute hedges, ahead of the upcoming winter 2014/15 trading period.
