ENERGY FIRM OPENS DOOR TO THE MOST IMPORTANT MARKET IN FLEXIBLE ENERGY

B

ritain’s leading demand response aggregator, Flexitricity, has launched a new electricity and gas supply service, which will bring the flexibility of industrial and commercial energy users and small generators into the Balancing Mechanism – the real-time electricity market National Grid uses to balance supply and demand. Minister for Energy, Connectivity and the Islands, Paul Wheelhouse MSP, welcomed the launch, which will give businesses direct access to both wholesale energy markets and the Balancing Mechanism (BM). Energy prices in the BM can reach £2,500/MWh, compared to around £50/MWh in wholesale markets. The BM has previously been the preserve of traditional energy suppliers, such as the Big Six. By taking the flexibility of industrial, commercial and public-sector energy users right into the BM, Edinburgh-based Flexitricity will give its customers a slice of this premium market, while cutting the cost for National Grid and all energy users. Speaking of the launch, Energy Minister Paul Wheelhouse, said: “The development of a flexible electricity system is a key aspect of our vision towards achieving greener, more efficient energy. “Energy ‘aggregators’ play a vital role in helping us to manage our electricity systems as we move towards a more decentralised system, ensuring that many

more consumers can benefit from providing flexibility to their local electricity networks. “By taking advantage of the changing energy market, innovative products and services like Flexitricity+ can help to drive down costs for consumers and industry, champion innovation and growth, and help us to meet the ambitions laid out in the Energy Strategy.” Rachel Maitland, Flexitricity’s Head of Supply, added: “Today marks a significant day for our customers, as well as billpayers across the country, by making our electricity system greener, fairer and more efficient. Flexitricity+ is a disruptive new proposition and we’re very proud to be the first to deliver it. Our track record of innovation, strength of existing operations and technical expertise mean that we’re ideally positioned to maximise the revenue our customers can earn from this marketplace. “We’re currently in discussion with a range of organisations who see the powerful business benefits of using our new service. Community energy schemes, combined heat and power (CHP) generators, cold stores, renewables, gas peaking plant and battery developers are all in a very strong position to benefit from Flexitricity+.” The first customer contract secured is with Gateshead Energy Company (GEC) – a subsidiary of Gateshead Council, set up in 2016 to serve Gateshead with low cost, low carbon heat and power. GEC operate the

Gateshead District Energy Scheme, which in 2017 won the Association for Distributed Energy’s Visionary Project award. As a participant in the Balancing Mechanism, Gateshead Energy Company will generate revenue through its Combined Heat and Power (CHP) plant – an excellent source of flexible reserve energy – which, as a publicly owned company, ultimately will increase support for community services. Jim Gillon, Energy Services Manager, acting for Gateshead Energy Company, said: “As a publicly owned, local heat and power generator, Gateshead Energy Company needs to continually look for ways improve its income base in order to support a low-cost energy offer to local customers. Flexitricity has already helped GEC do that since 2017, with access to the Capacity Market and reserve power markets. “When we went to the market recently to seek a new electricity supplier that could also help us access the Balancing Mechanism, Flextricity’s proposal was clearly the best value solution for GEC, so, we are very pleased to be able to broaden our relationship and to build on the excellent service we have received from Flexitricity to date.” www.flexitricity.com

Renewable energy sector empowered to supply government

T

he government is making it easier for public bodies to reduce their carbon footprint, by launching a new agreement which makes renewable energy easier to source. The public sector currently accounts for around 2% of UK greenhouse gas emissions but the government is committed to reducing this figure. The OJEU contract notice for HELGA (Heat Networks and Electricity Generation Assets) Dynamic Purchasing System is now live for suppliers. It will help public bodies and the wider public sector to find the right suppliers for solar panels, wind turbines, heat networks, battery storage and more. The system supports the government aim to maintain and improve UK energy security, and the way it has been designed also helps level the playing field for small and medium-sized businesses by allowing large schemes to be

4

broken into smaller, more biddable projects. With a projected spend of £800m over the lifetime of the agreement, the new HELGA DPS offers a great opportunity for suppliers to be involved in the forefront of the public sector’s drive to reduce their impact on the environment. Each customer using the system will be able to select from a range of services: • Energy Advisory, Design and Technical Services: Technical services relating to advice and design of any demand management or generation type • Delivery Services: Delivery services to install, manage and maintain any demand management or generation type • Energy Purchase Agreement: Provision of Energy Purchase Agreements through direct or indirect opportunities

COUNCILS JOIN FORCES TO TACKLE FUEL POVERTY IN LEICESTERSHIRE

P

eople living in Leicester and Leicestershire will soon be able to buy green energy from a not-for-profit company that aims to provide some of the cheapest gas and electricity on the market. Set up by the city and county councils, Fosse Energy aims to tackle fuel poverty by offering competitively priced energy to domestic customers and by encouraging people to switch from other suppliers’ inflated tariffs. Fosse Energy’s tariffs will be available to anyone living in the city, the county and the wider East Midlands who wants to buy green energy from a not-for-profit organisation. Deputy city mayor Cllr Adam Clarke said: “We’re committed to tackling fuel poverty in the city and helping those least able to pay their energy bills. “We know that around 10% of households experience fuel poverty, and we know that many people pay over the odds for their energy – especially those on pre-payment meters. “What Fosse Energy will do is to give people the option of buying their gas and electricity from a publicly-owned company that has

no shareholders to please – which means its tariffs will always be among the cheapest on the market and will offer a very competitive alternative to the big six energy companies. “By teaming up with an established energy supplier, we will be able to provide a tried and tested service that’s backed up by a dedicated customer service team – so anyone thinking of switching will be able to do so with confidence.” The two councils have appointed Robin Hood Energy as Fosse Energy’s gas and electricity supply partner. Wholly-owned by Nottingham City Council and consistently one of the cheapest suppliers in the East Midlands, Robin Hood Energy will provide both the infrastructure and the full range of customer services to Fosse Energy. Customers will be able to choose from four tariff options – with 100% renewable electricity provided in each case. Deputy leader of Leicestershire County Council Cllr Byron Rhodes said: “One of our top priorities is to improve the quality of life for people living in Leicester and Leicestershire. Fosse Energy will contribute to that by offering low-cost tariffs.

“We want to ensure people in our communities can easily heat their homes using a sustainable source that’s affordable. That’s why we’ve ensured Fosse Energy offers renewable electricity across the board. “We are very excited to be launching Fosse Energy which we hope will make a big cost saving to households.” City and county council employees have been able to sign up for Fosse Energy’s tariffs since the summer but, from today (Thursday 1 November) anyone living in the city, the county or the wider East Midlands will be able to switch to Fosse Energy. Anyone who hasn’t switched their energy supplier in the last two years is likely to save money by switching to Fosse Energy, or an alternative provider. Customers selecting Fosse Energy’s green energy tariff will get electricity which will be certified as being sourced from UK-based wind and solar generators. Fosse Energy will also actively look for opportunities to support new schemes, but some of the energy provided will be from existing UK-based projects. www.fosseenergy.co.uk

Energy storage capacity set to soar, 300 UK-based companies involved in new sector

A

new database to be launched by RenewableUK shows a massive increase in battery storage capacity is set to take place – enough to power nearly half a million electric vehicles. Planning applications in the UK to install just 2MW of battery storage capacity in 2012 have soared since then to a cumulative total of 6,874MW in 2018. (92% of applications for storage projects are approved first time). The database will allow RenewableUK members to access comprehensive information on nearly 400 UK energy storage projects. It will show where operational projects are located on an interactive map, as well as schemes being planned and under construction, including those sited alongside solar, wind and tidal energy projects. It also reveals that the average capacity of applications for new battery storage projects has increased from 10MW in 2016 to 27MW today, and that

more than 300 UK-based businesses are operating in this new sector. 3.3GW of storage capacity (including hydro projects) is now operational in the UK and a further 5.4.GW has planning consent – including 4.8GW of battery storage, which is enough capacity to fully charge 480,000 electric vehicles. The database was launched at the first joint conference on energy storage held by RenewableUK and the Solar Trade Association, in London on Monday 5th November. The conference explored what our energy system would need from storage to achieve 100% of our power from renewable generation, and the new technologies that could get us there. Developers, investors, representatives from Government, National Grid, Ofgem, legal professionals and policy analysts examined the new business models and energy services which are already up and running, and the shape of

those to come, as well as the potential obstacles standing in the way of the rapid development of a low-carbon system. RenewableUK’s Executive Director Emma Pinchbeck said: “The energy sector is breaking new ground by making an unprecedented transition to a clean, flexible system which will power our country in the future. Energy storage is already playing a key part in that, from small local projects to grid-scale schemes. We’re decentralising the way the power system works and delegates heard how an increased share of wind, solar and storage on the grid could transform UK energy markets”. The Chief Executive of the Solar Trade Association Chris Hewett said: “Energy storage has already begun to unlock the full potential of wind and solar energy, and it’s happening faster than almost anyone anticipated. It’s clear that storage will be the foundation of a smart, flexible and decarbonised future energy system. www.renewableuk.com

WORLD’S FIRST ‘PROSUMER’ RESIDENTIAL COMMUNITY HEAT AND ELECTRICITY NETWORK WINS NATIONAL AWARD

T

he first ‘prosumer’ community heat and power (multi-vector) energy system in the world, based at the University of Nottingham, has won the Decentralised Energy Innovation award category 2018. Project SCENIC (Smart Controlled Energy Networks Integrated in Communities) is a small-scale local energy system comprising a low temperature heat network, smart electricity network, thermal and electrical energy storage serving seven residential properties at the Creative Energy Homes test facility, on the University Park campus. The project is acting as a pioneering research facility for the transition towards domestic distributed electricity and heat generation. By incorporating lowtemperature district heating there are improved efficiencies resulting in less energy consumption through reduced heat losses. The community energy system has also enabled all seven properties to be “prosumers” – both buyers and sellers of heat. Each home can generate and supply heat to a central thermal store, while at the same time taking heat from the network for space heating and domestic hot water. The heat generators include a biomass boiler, solar thermal collectors, gas boilers and a PV-battery connected immersion heater. The prosumer concept and distributed generation on this scale has never been done before. Project SCENIC is led by Mark Gillott, Professor of Sustainable Building Design at the Faculty of Engineering, in collaboration with a team of sustainable energy experts at the University including Dr Rabah Boukhanouf, Dr Lucelia Rodrigues, Professors Gavin Walker and Mark Sumner. The project was enabled through infrastructure funding from the Innovate UK-funded Energy Research Accelerator (ERA). Professor Gillott explains: “Project SCENIC represents the future of community heat networks and disturbed generation. Not only is it one of the first operating low-temperature heat network in Britain, it is also promoting the decentralisation of heat production by allowing home owners to be both the buyers and sellers of heat. By putting the power back into the hands of home owners, there can be a reduction in energy bills, distribution heat losses and carbon emissions.” When compared to a conventional base case of gas boiler supply local demand, each

6

home owner could save £632 a year through saving, selling and buying energy. Additionally, as the network is reliant on a range of distributed energy generators, security of supply is less of a problem. If one generator fails, there are still six to eight others available. As a pilot, SCENIC has informed the first real-world community energy demonstrator in the UK on a sustainable housing development, comprising 400 homes at the Trent Basin in Nottingham. The Trent Basin scheme has been funded by Innovate UK and ERA. Staged by the Association for Decentralised Energy to showcase industry achievements of the present and innovations of the future, the winners of eight different categories were announced at a black-tie dinner, held for 450 industry leaders at the City of London, Guildhall on October 24. At the news of the win, Professor Gillott praised the project team for their perseverance in achieving this award and gave a special acknowledgment to PhD candidate Sean Jones for his hard work on SCENIC. “This award illustrates the importance of innovation by developing new decentralised energy infrastructure capable of utilising onsite micro renewable energy generation across the energy vectors of both heat and power. “Our unique test bed at the Creative Energy Homes integrates a smart grid, on-site generation, smart in-home technologies, electrical and thermal energy storage technologies, a low temperature heat network and hydrogen technologies,” Professor Gillott adds. Emma Kelly, Chief Operating Officer for the Energy Research Accelerator (ERA), said: “I am delighted that the University of Nottingham team has won this award for their groundbreaking research work into community energy, it is well deserved. The learnings from Project SCENIC are being applied in the large-scale demonstrator at Trent Basin in Nottingham, where ERA has supplied the funding for the equipment needed, such as the shared community battery, solar-farm and the interactive energy hub. The aim of Trent Basin is to actively demonstrate how a community can generate, store and share its own renewable energy, reducing carbon emissions and the energy costs for all of the residents.” Email: mark.gillott@nottingham.ac.uk

ECA scheme closure looming, warns Remeha

A

s part of the 2018 Budget, the Chancellor has announced the closure of the enhanced capital allowances (ECA) scheme from April 2020. Businesses looking to invest in energy efficiency measures should plan now to take full advantage of tax relief opportunities, says Remeha. The Government’s measure to close the enhanced capital allowances scheme will end the first year allowance on the Energy Technology List (ETL) and the Water Technology List (WTL), including the associated first year tax credit, from April 2020 onwards. Paul Arnold, Product Manager at Remeha, says: “The ECA is a popular scheme that has been in place since 2001 to encourage the manufacture and uptake of increasingly energyefficient products and technologies. “Energy efficiency is one of the most cost-effective ways for businesses to improve the energy performance of their buildings. As a large user of energy in a building, heating is frequently a starting place for efficiency measures. And by providing accelerated tax relief on higher energy-efficient equipment, like our own condensing boiler range, the ECA has helped businesses take a whole-life approach to costing for greater longterm energy and emissions savings. “Businesses will still have an annual investment allowance (AIA) of £200,000. But we would advise any businesses intending to invest in energy efficiency upgrades to plan and budget in the next year. This will allow them to take advantage of tax relief for ETL products via the ECA if the AIA maximum has already been met.” The ECA scheme was introduced in 2001 to provide a cash-flow boost to incentivise the use of more energy-efficient equipment and, in so doing, support the nation’s move to a low-carbon economy. First year allowance schemes currently allow 100% of the costs of the investment in qualifying equipment to be written off against the taxable income of the period in which the investment is made. There is no cap on the amount that can be claimed for profit-making businesses. Qualifying costs include the installation and transportation costs in addition to the cost of the equipment.

ONE GIANT LEAP FOR ENERGY EFFICIENCY E.ON is working with the European Space Agency (ESA) and Earth observation specialist Astrosat, capturing satellite imaging data to accurately identify areas across the UK where energy efficiency measures are most needed.

T

he project will use near real-time and archived data gathered from orbiting satellites – including optical sources, thermalinfrared for heat mapping and air quality and pollution tracking – which will combine with Astrosat’s ThermCERT software to help tackle issues such as housing condition and insulation, air quality, and even traffic management. When cross-matched with existing housing or data on vulnerable customers, the unique platform will provide local authorities and even entire cities with a street-level view of where improvements are most needed. This means they can better target their approaches to upgrading housing stock, optimising energy efficiency installations, improving air quality or easing congestion across communities. Current energy efficiency programmes often rely on door-to-door visits or doorstep mailings in order to talk directly to customers and analyse their specific needs. The large amount of data which can be captured using satellite technology means a bigger and more accurate picture can be created quickly, which improves the success rate of installation works. During the project, E.ON and Astrosat, with the support of ESA, will develop the system for around 18 months, including a city-scale trial. ESA’s ambition is for space data to unlock greater business and societal opportunities and E.ON’s scale across Europe creates the potential to roll out the project across other countries once the UK trial has successfully concluded. The UK is a founding member of ESA and, through the UK Space Agency, invests more in its Business Applications programme than any other country in Europe. Business and Energy Secretary Greg Clark said: “This government-backed technology could boldly go where no technician in a van has gone before, with the potential to pinpoint households in fuel poverty or those at risk. Matched with government data, this heat mapping technology could mean less time spent on the road and more time dedicated

to upgrading homes though our £6bn energy efficiency ECO scheme – the sky’s the limit. This is our modern Industrial Strategy in motion, with our worldleading space sector showing how innovation can deliver practical solutions to real-life issues.” Michael Lewis, E.ON’s UK Chief Executive, said: “Delivered on the doorstep but driven by big data gathered from Earth orbit, our work with Astrosat, in collaboration with ESA, is about using the almost endless possibilities of space to deliver real benefits on the ground. This truly innovative and exciting project is about harnessing the power of space, alongside our experience working with local authorities and delivering real change in terms of fuel poverty and carbon emissions, to help reduce heat loss and unnecessary energy expenditure in regional areas across the UK. This is a UK trial at this stage but all involved have the ambition to prove the benefits across countries and continents to help create a better tomorrow.” Fraser Hamilton, Chief Operating Officer at Astrosat, added: “We’ve applied our technical knowledge to E.ON’s wealth of experience with local authorities and ESA’s space acumen to create something truly unique that will add real value to the UK energy market. Astrosat’s ThermCERT system allied to E.ON data provides a space-age solution to Earth’s energy challenges by leveraging the power of space technology to deliver real-world benefits. In a world where data is routinely generated before a problem or application is known to exist, we are able to intelligently cross-correlate and fuse that data from in-situ satellites; this solution will greatly enhance E.ON’s ability to identify communities in need of assistance.” Nick Appleyard, Head of the Downstream Business Applications Department at the European Space Agency, said: “Our Business Applications programme is dedicated to supporting space-enhanced services with two objectives: to generate growth for the

industrial partners, and to benefit society at large. ThermCERT checks both of these boxes. We have a two-pronged approach to supporting the green energy revolution. Initiatives like ThermCERT show how space assets can help to reduce costs and improve energy efficiency in existing neighbourhoods. In parallel, we are open to proposals for space services that help to create Green Neighbourhoods by improving their initial design.” In its first iteration, the platform helps to locate and provide targeted support for the most vulnerable individuals in society. Future iterations will leverage the growing wealth of high resolution commercial data that is now coming online. E.ON and Astrosat expect the product to be ready for use in a UK pilot by Q3 2019.

How it works The Earth observation data can be viewed independently, layer by layer, or intelligently combined with existing data sources such as Department of Work and Pensions information at a community level, into a specific tool that focuses on helping to answer specific questions or problems. This enables an approach that is much more efficient than existing methods and can proactively locate whole areas or communities that would most benefit from improvements, rather than relying on input from residents who might be wary of reporting themselves as vulnerable or in need of extra help. Initially designed to focus on targeted energy efficiency measures, the tool is built to scale to any regional geography and utilise many types of data. The platform is built to allow for the development of additional layers of data that can be simply plugged in, extending the potential to other opportunities such as air quality monitoring. www.eonenergy.com/blog/2018/ October/satellite-images-technology

OPINION

CUSTOMER COMPLAINTS: A VALUABLE WINDOW INTO YOUR SERVICE Monica Mackintosh, customer services director at utilities customer engagement specialist Echo Managed Services.

E

very customer complaint is a disappointment and an indication that in some way a company has failed to live up to its customers’ expectations. It’s seen as an important customer service measure across the utilities sector; complaints volumes, speed of resolution and key complaint themes are regularly measured and publicly reported. The results of these reports do not make the most positive reading. Ofgem’s latest customer complaints survey highlighted that 57% of customers were dissatisfied with how their complaint was handled, with Ofgem ordering 11 of the UK’s suppliers to improve how they deal with complaints. The July 2018 ICS Customer Satisfaction Index, published by the Institute of Customer Service highlighted further concerns – 10.6% of customers claiming they’d made a complaint to their energy provider in the last three months (higher than the UK all sector average) and 51.6% of customers stated their complaint took longer to resolve than expected. The utility sector was once again among the lowest-scoring sectors for customer satisfaction, and billing was highlighted as the number one thing customers would like to see improved. Whilst these reports give a snapshot into the state of energy customer complaints, and improving complaint handling should clearly be a priority for the sector, surely prevention is better than cure? Customer complaints offer a valuable window into your service offering, viewed from a customer perspective and are therefore a key opportunity for service improvement; to find the issue, fix it and monitor impact. Of course, this can be easier said than done. With a blend of people, process and technology at the heart of service, organisations may face a number of barriers when it comes to transformation.

8

However, failing to overcome obstacles can’t continue in the long term, with energy companies needing to continually evolve and innovate in an increasingly competitive marketplace. So, what steps can be taken?

PIN-POINTING THE ROOT CAUSE Learning from customer complaints, and taking action to make changes, all starts by identifying the root cause – or causes – of the customer’s dissatisfaction. A robust complaints database and reporting dashboard are essential resources to examine service failure themes and root cause trends, as well as revealing the cost of getting things wrong. Naturally, this should be combined with insight from other key barometers such as customer satisfaction survey information and employee feedback, and often this holistic view will pinpoint the same themes, further validating the need for change. However, data and insight is only of true value if it used effectively to drive change. This relies on resource, the commitment to analyse the data, and looking beyond it to uncover the real issues. Deep dive sessions can help, taking a complaint theme and bringing teams together to examine the issue from the customer viewpoint and discuss what

ENERGY MANAGER MAGAZINE • NOVEMBER/DECEMBER 2018

went wrong, where and most importantly what can be changed to improve service.

A CULTURE FOR CHANGE Everyone must be on board. If the complaints department acts as, and is viewed as, a silo, achieving change can be difficult in the midst of differing department priorities, budgets and viewpoints. The customer view must be at the heart of the whole company, led from the top down. Customer experience should be viewed as the responsibility of all, and all teams should be aware of how their actions impact on the customer and customer experience. Board level steering groups can help – including representation from all areas of the organisation; resulting in joint decisions and accountability for change programmes identified through the customer complaints window.

OVERCOMING INEFFECTIVE SYSTEMS Technology should enable innovation, great efficiency and improved service. However, many utility providers are being let down by inflexible software that is hindering their agility and customer experience aspirations. Modernising cumbersome and outdated legacy systems is often a


OPINION priority when it comes to driving proactive service change, but time, budget and resource constraints can be real barriers in achieving aspirations. Add on top of this, high profile examples of system changes that have led to increased customer complaints, and it’s clear that organisations may be cautious when investing in this area. However, given the competitive nature of the market and evolving customer expectations, it has to be time for change. The alternative is to lose the opportunity to fix root complaint causes, put in place costly work-arounds, or rely on lengthy software provider led change requests and updates. This is especially true when it comes to billing; currently the most common reason for customer complaints. Many legacy billing and CRM systems get in the way of delivering real change and can ground even the best customercentric improvements. This is simply not a model fit for the future. Deploying a new-age solution, built for easy configuration and scalability, can enable and empower energy companies; growing with their ideas and supporting a culture of being ahead of the game. Implementation timeframes and risky data synchronisation processes can both be reduced by choosing best of breed native billing and CRM technology – operating from a single date store and offering a zero-integration model. Such software has the potential

to bring about real change in customer-facing operations, empowering utility providers to improve their customer journeys and reduce complaints as a result.

– although not all directly customer facing – can be a cause of complaints. Although customer service might not be their direct concern, it’s vital they view customer experience as a priority to help avoid unnecessary customer dissatisfaction and potential complaints.

PEOPLE – YOUR GREATEST ASSET

TRANSPARENCY

Your teams, and not just frontline customer service staff, can sometimes cause customer complaints – although not always knowingly, or through any fault of their own. Whilst tone and attitude are arguably within an employee’s control and there for avoidable, knowledge and skills gaps often result from ineffective new starter programmes, failing to keep teams updated, and insufficient training and coaching support. Investing in people, and taking the time to listen to their concerns, can support complaint reduction. Also, recognising and rewarding those who are doing well will help drive the right behaviours across your teams. Gaining insight from employees is arguably as important as gaining insight from customers. For example, if they find a particular aspect of a customer journey troublesome, it’s likely that customers do too; involving frontline teams in customer journey workshops can really help when coming up with practical ways forward. However, don’t forget to be inclusive in your approach. Back office teams, field based teams and outsourced partners

Finally, being honest and transparent cannot be underestimated, especially in a market in where customer choice is greater than ever and customer retention and loyalty are therefore key concerns. A common method used internally, in employee engagement programmes, is a ‘you said, we did’ mechanism, where employee concerns are publicly acknowledged and addressed. Why not take this approach when it comes to customers, being transparent around complaint themes and how you’ve listened and changed. This lets customers know you take their views seriously and are prepared to act on their concerns.

LISTEN AND LEARN So, whilst customer complaints are unwanted, they do offer an instant view on service from the perspective of your most important stakeholder – the customer. Learning from the organisation’s mistakes can help turn disappointment into positivity; fostering a customer-led change driven agenda to drive continuous service improvement. Of course, this is likely to involve a test-learnimplement approach – as it isn’t realistic to always expect to deliver the desired effect on the first go; keep tweaking and trying again. Ultimately, what’s important is that you listen and learn. In our experience this approach can have a huge impact on overall complaint reduction. www.echo-ms.com

WILL BREXIT BE THE DEATH OF ESOS?

W

ith the UK government currently negotiating our Brexit withdrawal, many people are asking how it may affect ESOS. Although it is currently preserved in UK law, there is no concrete evidence to say it will remain should we leave the EU, so if it’s set to become superfluous should we even bother complying? ESOS introduced in 2015, is the Energy Saving Opportunities Scheme (ESOS) part of the Energy Efficiency Directive from the European Union. It is the UK element of the Environment Agency’s plan and was brought in to encourage large businesses to become more sustainable by recognising and reducing carbon based fuel. To qualify you must have • Over 250 employees or more • A turnover greater than £42.5m • Or a balance sheet greater than £36.5m If you fall into this bracket you are required to undertake assessments every

4 years to identify cost-effective energy saving measures on supplies to buildings, industrial processes and transport. Simon Smith CEO of BrightSourced Energy says: “Well first and foremost the Brexit transition period goes beyond the ESOS deadline for Phase 2, so qualifying businesses will still need to adhere to compliance prior to December 2019. Failure to do so can result in hefty fines anywhere between £5,000 to an eye watering £90,000. Coupled with the embarrassment of your business being named and shamed, now is not the time to stall. We will have to see what happens after Phase 2, but we will have another 4 years to work that out anyway.” Another problem organisations have in achieving compliance for the 2019 deadline, is since Phase 1 in 2015, many qualified ESOS assessors have not kept up their accreditation, mainly due to the cost of it and the fact their services are redundant between the 4 year phases, as well as the uncertainty as to whether

the scheme will continue post Brexit. Therefore for Phase 2, there are now only around 250 registered and qualified lead assessors to choose from that are registered with the approved professional bodies. Smith says: “For Phase One, there were circa 350 qualified assessors, to manage over 7,000 UK businesses who qualified for the scheme. This led to too much work for the resource available and as it got closer to deadline, some businesses were having to pay ridiculous day rates to get their reports completed on time. For Phase 2, there are more businesses that need to qualify and less assessors available, my advice is get your report done sooner than later, as there is just over 12 month left to achieve compliance” So it would seem whether the death of ESOS will happen post Brexit is unclear. However what is certain, is that it has already had an impact on the number of qualified people available to help businesses comply with Phase 2; so it’s inevitable that costs will go up and there may be a problem with organisations being able to complete their reports on time, due to lack of resource. So acting early is the key, whether you are waiting to see the what the impact of Brexit on ESOS has or not. www.brightsourced.com

ELMHURST ENERGY SUBMITS ITS RESPONSE TO GOVERNMENT’S CALL FOR EVIDENCE ON EPCS

E

lmhurst Energy has issued a response to Government’s vital ‘call for evidence’ on how Energy Performance Certificates (EPCs) are currently performing in buildings. The outcome of this consultation is extremely important to the energy assessment industry and its membership and the Elmhurst team has taken significant time to consider and reflect on the document. The response, where possible, also includes the opinions of Elmhurst members, 150 of whom attended the recent Elmhurst 25th Anniversary conference, to discuss EPCs. Central to the Elmhurst message within the response are the following nine points: 1. Energy Certificates should always reflect the current state of the building and should be re-issued whenever there is a change that impact upon the energy performance of the building. To reflect current fuel prices, an EPC should lapse after one year to ensure estimates and recommendations are relevant. 2. The planning and building regulations process often requires a prediction of a building’s energy performance before construction starts. It is critical that the quality of such predictions is on par with the EPC and therefore should only be undertaken by accredited energy assessors whose activities are overseen by an approved scheme.

3. Display Energy Assessments to be required for all buildings that are visited by members of the public including shops and offices, as well as buildings owned by government and local authorities. 4. Occupier engagement is restricted because the EPC is an asset rating for which the occupancy profile is not understood. Each EPC (asset rating) should be supplemented with an occupancy assessment that improves the energy consumption estimates and recommendations particular to the current occupier and their lifestyle. There is a need for independent advice and energy assessors are well positioned to provide this. 5. As EPCs are now being used for setting minimum standards it is important that they are consistent over time. Elmhurst believe that an EPC rating should be based on a fixed standard, such as primary energy, rather than a variable such as cost or carbon. 6. EPC data should, with reasonable controls, be open for stakeholders to use to demonstrate possible improvement, and to improve

enforcement authorities by linking to Land Registry and Trading Standard systems. 7. Investment is required in the SAP, RdSAP and SBEM methodologies to ensure that results of real world testing is fed back, in a closed loop model, to constantly improve accuracy. 8. The approach to assessing Houses of Multiple Occupancy (HMOs) should be simplified as most can be assessed using RdSAP as a single dwelling. 9. No building should be exempt from requiring an EPC. PRS/ MEES, and other legalisation, can then be amended to allow exemption based upon the restrictions placed by planning and conservation restrictions. “We hope the message is clear that Government need to build upon the excellent work of EPCs and energy assessors, and move into areas such as encouraging more action,” says Martyn Reed, Managing Director, Elmhurst Energy. “We trust that the feedback they receive is quickly analysed and new initiatives come through to ensure that buildings are warmer, cheaper to run and cleaner for the environment.” To view Elmhurst’s final response in more detail, please visit: www.elmhurstenergy.co.uk

WE NEED TO BE AMBITIOUS TO REDUCE BUSINESS ENERGY CONSUMPTION

T

he Government recently set out its plan to improve energy efficiency in businesses by 20% by 2030. This is a step in the right direction – but to those of us who help business use their energy more efficiently; it’s nothing like ambitious enough. Energy optimisation and reduction must be made central to a businesses’ strategy, and only by pursuing an ambitious target can the Government ensure this takes place. We know that inefficient energy usage can hit the productivity and profit of businesses, but at the moment not enough is being done to facilitate or incentivise change. In 2015, business used 422TWh of energy, of which nearly half was used in buildings – the scope for improvement is huge. So what can be done? Awareness is paramount, providing energy efficiency advice and support that is clear, simple and accessible will be critical to success. As 50% of energy consumption is through SMEs, bespoke support needs to be produced for this sector, where possible working closely with trade bodies to make sure the message reaches the right audience. To be impactful guidance must demonstrate the clear benefits and impact on the bottom line. To support the improved awareness there must also be corresponding incentives to stimulate action. Currently most of the legislation encouraging behavioural change is punitive, but if the Government really wants to see significant improvement in energy reduction then the tax breaks provided will need to be made deeper, with a larger benefit provided for selecting for the most effective and efficient products. Accreditation for reaching certain levels of efficiency could be a driver for more public facing businesses, where reputation matters. The ability to obtain quality data is also critical to progress. It is anticipated that Internet of Things ‘IoT’ technology will enable a much better command of ‘big data’, helping to provide new insight which can then be turned into meaningful trends and indicated actions. In the nearer term the introduction of half-hourly data is of critical importance

Kevin Greenhorn, Managing Director, Energy Solutions, SSE Enterprise

as it will see the end to the scourge of estimated bills, which can make it difficult to accurately assess project benefits. Improved data will also allow for better benchmarking across business sectors. In the competitive business environment being able to demonstrate that a business is operating below the industry standard can be an invaluable tool to incite action. While there has been some benchmarking done previously

this is now out of date, a government run online benchmarking tool could provide a suitable trusted source of insight. By reducing their energy use businesses can become greener, more efficient and more productive. Now is the time to be ambitious, the business community and the wider environment only stand to gain. www.sseenterprise.co.uk

NHS Tayside’s proactive approach to sustainability ensures that they have an informed understanding of where and how to invest in energy saving initiatives Upgrading the high voltage assets at the Ninewells Hospital to state-of-the-art, super low-loss amorphous transformers was one such opportunity that would present the hospital with multi-benefits. Besides delivering energy and carbon savings, the hospital will increase the resilience of the hospitals critical power network in line with the business continuity management programme.

Replacing just one old inefficient high voltage transformers will save the hospital over £7,300 each year Ninewells Hospital undertook an energy study of the existing transformer’s consumption rate to establish the real potential for energy and carbons savings. The results conclude that by replacing the existing 11kV:433V unit from 1967 with a 11kV:415V Wilson e2 amorphous transformer of the same capacity, combined energy savings of approximately 61000 kWh per annum would be realised.

Lasting benefits for a sustainable NHS The transformer room in the molecular biology wing at Ninewells houses four transformers of a similar age, presenting the hospital with the prospect to significantly reduce their energy and carbon. The entire transformation project at Ninewells Hospital will save NHS Tayside approximately 61,000 kWh per annum per transformer. Each transformer will provide carbon savings of 27,113kgs and energy cost savings of over £7,000 a year. Once all four transformers are online, the project is forecast to provide energy savings over a 5-year period of 304,000kWh, approximately 1.79% of the total electrical energy consumption at T1. This, in turn, equates to a reduction in carbon of approximately 135,564kg over the same 5-year period (total) and an energy cost saving of over £143,000.

INSULATION CAN HELP LANDLORDS MEET THEIR ENERGY PERFORMANCE OBLIGATIONS AND LOWER ENERGY BILLS

P

rivate sector landlords of the coldest properties in England and Wales will be required to bring their buildings up to property energy rating Band E, saving their tenants £180 on average per annum. Since April 2018 landlords have been expected to reach this level when support such as grant funding has been available to cover the cost. However, the Energy and Clean Growth Minister Claire Perry announced (November 5th) further support for tenants in 2019. Landlords will be required to contribute to the cost of the energy efficiency measures to bring their properties up to Energy Performance Certificate Band E, or apply for exemption when upgrades cost more than £3500.

14

This follows publication in November 2018 of the UK Government’s response to the consultation to amend the Energy Efficiency (Private Rented Sector) (England and Wales) Regulations 2015. When looking at ongoing tenancies, residential landlords should be thinking longer term in any case. By making homes energy efficient with lower running costs, the attractiveness of the property in terms of comfort, property value and ongoing energy savings can be raised and often helps with tenant retention. After all, high tenancy turnover is costly with lost income between tenancies, together with fees for sourcing new tenants and the associated legal or contractual costs. Property values and rental income may also increase when

compared to more inefficient buildings. According to the Department for Business, Energy & Industrial Strategy these new regulations will cost landlords £1200 on average and will affect 290,000 properties, which represents around 6% of the overall domestic market. Claire Perry said: “While the vast majority of landlords take great pride in the properties they own, a minority still rent out housing that is difficult to keep warm. Upgrading these homes so they are more energy efficient is one of the most effective ways to tackle fuel poverty and help bring down bills for their tenants, saving them £180 a year.” Existing buildings can easily be brought up to high standards of thermal efficiency resulting in the lowering of


ENERGY MANAGEMENT fuel bills and a reduction in carbon emissions. The use of a high performance spray applied or injected polyurethane foam can substantially increase thermal performance. Polyurethane foam can be installed in the form of wall insulation, roof insulation, floor insulation or to fill voids and other areas to provide a seamless, thermal insulation barrier. The polyurethane insulant is a twocomponent liquid system which produces a highly-efficient blanket of insulation with an exceptional thermal conductivity figure. It is particularly cost-effective and easy to apply to a wide variety of substrates. Its closed-cell nature renders it very resistant to moisture ingress and grades are available which achieve both Class 1 and Class 0 fire ratings when tested to BS 476 Part 7 and 6 respectively. The urethane foam can be applied in any thickness to suit the insulation requirements of the building. For cavity walls injected polyurethane foam offers high thermal performance in comparison with other insulants. The addition of cavity wall insulation should bring the walls up to current Building Regulations. The insulant acts as a barrier to heat loss, prevents draughts, and can also help with the reduction of

airborne sound. This form of cavity wall insulation can be used in flood-plain areas to provide an additional barrier against water ingress through the walls. Spray-applied polyurethane foam is used in roofing applications to insulate or stabilise the roof. The insulant bonds tiles where nail fatigue exists, but where the roof is otherwise sound. The foam acts as a protective barrier, preventing

the ingress of wind-driven rain and snow, and will provide more resistance against storm or impact damage. The British Urethane Foam Contractors Association (BUFCA) is the national trade association representing professional installers and suppliers of spray-applied and injected polyurethane foam systems. www.bufca.co.uk

VICKERS’ ENERGY MANAGEMENT SYSTEM MAKES SAVINGS ALL ROUND

T

hanks to an energy management system (EMS) from Vickers, DS Smith – one of the world’s leading providers of corrugated packaging and a specialist in plastic packaging – has enjoyed impressive cost savings in excess of 60%, and reduced its carbon footprint by 27 tonnes over a three year period. Installed in 2015 at the DS Smith site in Sheerness, Kent, Vickers’ EMS was primarily specified to control the company’s consumption of gas in their warehousing facility. The investment was also projected to reduce carbon emissions and make cost savings of 30%. However, after just three years, the company has more than doubled its projected savings by reducing gas expenditure by a remarkable £5,665. Commenting on this achievement, Dave Almond at D S Smith said: “Thanks to our investment in a Vickers’ EMS, we have not only reduced our CO2 emissions, we have saved a significant amount of money by reducing our energy consumption, and this has more than covered the cost of our original investment. “Moving forwards, it’s reassuring to know that we will continue to reap the rewards of an accurate heating control system that delivers maximum energy efficiency, whilst enjoying full after sales support from Vickers,” added Dave. Vickers’ Energy Management Systems enable commercial and industrial premises to gain control of their heating and reduce energy bills and CO2 emissions at the same time.

the performance of a heating system, the EMS can eliminate any wasted energy with precision accuracy. Thanks to an advanced self-learning programme, the system can also calculate the necessary burn time for each heater to achieve its target temperature, and can detect how long a heater will take to cool down and switch off accordingly. The EMS is also compatible with lighting systems. Commenting on DS Smith’s results, Chris Pearson, Managing Director at Vickers said: “Very often, companies are deterred by the capital outlay required to install an EMS. However, as demonstrated by DS Smith, the payback period for the initial investment typically can be up to just 2 or 3 years depending on the current usage, and thereafter, significant savings in energy and CO2

emissions can continue to be enjoyed.” Vickers’ advanced EMS can be monitored from any location thanks to cloud-based technology. In addition to viewing performance and energy usage, changes can be made from any internet enabled device thereby providing the ultimate in control. Monthly reports can also be generated to show the benefits gained from installing this system. The system comes with a complimentary 12-month warranty and service agreement that includes an onsite annual health check, engineer call outs, and software updates, and this can be extended at any time.

TREND ADDS HAND/OFF/AUTO IO MODULES TO ITS IQ®4 RANGE

T

rend Control Systems, the leading international manufacturer and supplier of state-of-the-art Building Energy Management Systems (BEMS), has announced that its pioneering range of IQ®4 controllers has been complemented by the introduction of an IO module with override functionality, which is available in both analogue and digital variants. The IQ®4 Hand/Off/Auto (HOA) modules make it possible to override plant when the controller/strategy is not achieving the results required for whatever reason. The modules can also be used to override plant to test if it is working correctly, for instance to check that boilers are fully operational before they are switched on after summer. Additionally, the HOA modules can be used for commissioning, as they work straight out of the box with no need to address the module or connect it to an IQ®4 controller. HOA modules have been designed to offer ease of use. Trend has produced labels that clip over the modules to give users the ability to individually identify each switch so even a non-specialist can easily identify what needs to be overridden. Both module options utilise a two-state operation and require no tools to operate – pressing the knob takes the channel in or out of override, and twisting the knob sets the status/ value of that channel. This means that a controls engineer can pre-set the value to be overridden so that when the overridden state is entered – which may be by a non-specialist – the module immediately goes to the value required with no additional adjustments.

Plant that is overridden and runs for eight hours a day could use up to three times as much energy. Therefore, in order to prevent wastage, the HOA modules offer various methods of indicating status. When a channel is overridden the button flashes, providing a clear indication that there is something that needs investigating. Additionally, an alarm can be configured on each channel so, when the override button is pressed, notification arrives at a Trend 963 Supervisor or IQ®VISION user interface. Finally, it is possible to provide indication of the status and value of the override on a 963 Supervisor or IQ®VISION schematic, so that it is clear on the page if any plant is being overridden. ‘Since it was introduced, the response to the IQ®4 range has been phenomenal and it is now one of the most successful

Through training and knowledge provision SGS can help create a dynamic culture of learning that greatly enhances stakeholder engagement. If visitors want to find out more about meeting the demands of the Energy Savings Opportunity Scheme (ESOS) or how ISO 50001 – the internationally

I would therefore encourage

products in our history,’ concluded David Field, product manager at Trend. ‘I’m therefore delighted that we have been able to extend its reach with the introduction of the IQ®4 HOA modules, which was the missing piece of the jigsaw for those countries where the ability to override plant is a common requirement in specification documents.

HOW TO AVOID DATA CENTRE MALFUNCTION

T

here are very few sectors where projected growth exceeds that of the data centre industry, which is expected to be worth more than £100billion by 2025. The digital age and subsequent technological developments only add to an alreadystrong requirement for data centres, and there are several reasons for this. Put simply, this trend is reflective of the fact that a company’s operationality can be easily streamlined to enhance the level of service customers now come to expect. So, what does this mean for the many organisations that are almost completely reliant on the uninterrupted functionality of servers? With the average cost of a data centre outage thought to exceed half a million pounds, the financial impact of failing to protect critical assets could not be more glaring. Despite that astronomical figure, many of the world’s largest companies still appear to give very little credence to the prospect of server failure – until, of course, it’s too late. A pre-emptive approach to monitoring your data centre can help prevent the dreaded breakdown

Carl Webb, HVAC Sales Director at Andrews Air Conditioning, outlines the implications of data centre malfunction and how having a contingency plan can be the difference between business continuity and catastrophe. scenario and avert any serious disruption. In telecommunication applications, redistribution points and communication endpoints – more commonly known as nodes – produce vast quantities of heat which needs to be constantly counteracted to prevent a crippling system failure. When nodes surrounding a central processing unit (CPU) reach or exceed temperatures of approximately 32°C, then that hardware enters a race against time before any lasting damage is caused. Even if a CPU can be replaced and your server appears to be functioning as expected at first glance, there’s still a strong possibility that you will encounter an issue further down the line.

ENERGY MANAGER MAGAZINE • NOVEMBER/DECEMBER 2018

If other vital components such as the power supply or memory are exposed to extreme temperatures, their susceptibility to collapsing dramatically increases. So, what causes this vulnerability? One of the most common reasons for severs faltering is insufficient temperate control inside the hosting application. Preserving the functionality of your telecommunications services should always be a primary objective which means those responsible for your facilities must ensure suitable cooling equipment is deployed inside the location. It is generally accepted that electronic hardware performs best at between 20°C and 23°C, underlining


ENERGY MANAGEMENT the importance of having a trustworthy high capacity air conditioning arrangement in place at all times. Unsurprisingly, having an adequate source of cooling is a fundamental requirement but far from the only thing you must consider from a safeguarding standpoint. It’s imperative that your data centre is correctly ventilated to allow enough space for cold air to circulate freely. Although having an effective air conditioning system is critical, it’s impact will be almost completely negated if there is not enough room for air to move. Perhaps the most overlooked variable, though, is the need to control moisture levels and humidity. Excessive dampness can cause machinery to corrode, short-circuit or even develop mould, which is as avoidable as it is undesirable. With that said, too little moisture in the atmosphere can also have a knock-on effect by increasing the likelihood of electrostatic discharge instigating a system crash. It goes without saying, but the repercussions of your data centre failing are varied and far-reaching which is why it is so important to take preventative measures at the earliest opportunity. In the first instance, there is a cost of detecting the original problem which involves the subsequent investigation into how it arose. This phase of action goes hand in hand with an attempt at containing the issue, which is solely aimed at limiting disruption and making sure its effect is minimised. Once an application has gone offline, your immediate priority will obviously be restoring networks and key systems. This is often easier said than done, however, and the financial impact of this process is difficult to calculate. Not all losses can be measured in monetary terms, however. There’s no doubt that a major data centre malfunction would affect the way in which the operator is perceived by clients, and that can have long-term ramifications. Trivial everyday complications can normally be rectified but a damaged reputation is far more difficult to repair. When disaster strikes, you’ll require the intervention of a 24-hour HVAC company that can dispatch engineers to your site immediately. A leading provider of specialist cooling hire solutions will pride themselves on having a genuine nationwide presence with depots and bespoke equipment located all around the country. By recognising the sensitivity of data centres and server rooms, trained technicians are extremely well-placed to recommend and install a cooling

package that has been specifically tailored to suit your environment. A trustworthy contingency service will ensure daily strategies are protected and guarantee business continuity even when faced with an outage. By constantly developing and improving the technology used in their modern air conditioners and chillers, a trusted supplier will be able to provide superior replacement equipment should your own cooling system lose effectiveness. Your chosen provider should pledge to respond to emergency callouts as quickly as possible and possess a tangible knowledge of keeping data centres online. A nationwide presence helps protect companies that have become increasingly dependent on the continued functionality of electronic hardware. Understanding the potential impact of failed IT systems enables engineers to react quickly, take

precautionary measures and install supplementary or substitute cooling apparatus to avoid costly downtime. The round-the-clock availability of high capacity air conditioning units should be coupled with a free site survey option if required by customers. Should something go wrong on site, clients will reap the benefits of professional technical advice preceding the implementation of an alternative cooling hire solution that befits your surroundings and process. If you’re not sufficiently prepared for offsetting warm server room temperatures and don’t have a set protocol to follow in the event something goes wrong, now is the time to take action. Why leave yourself in the precarious position of self-inflicted vulnerability when seeking expert advice is so easy? www.andrews-sykes.com

The exceptionally large Goodlight range allows customers to choose an LED light source that delivers exactly the right amount and type of light to each area. They switch on instantly at full brightness, are maintenance-free and guaranteed for five years. The advantages of converting to LED lighting for an organisation include immediate energy savings, superior light quality, safety and security.

IMMEDIATE ENERGY SAVINGS The main benefit of upgrading to LED lighting is the huge energy savings that can be made. Evaluation of Goodlight LED products has demonstrated energy savings up to 85% and in addition, maintenance savings of up to 100%

ENERGY MANAGER MAGAZINE • NOVEMBER/DECEMBER 2018

can be achieved. Typical return on investment calculations show full payback from as little as three months, therefore, a new installation can essentially be funded from the energy savings alone. The installation of Goodlight LED luminaires at various sites within London’s Heathrow Airport has resulted in immediate energy savings of up to 77%. Return on investment was on target and achieved within 24 months, following lengthy in-situ trials. Heathrow were delighted that Goodlight met their corporate lighting plan by exactly matching the colour output of existing lighting to suit their various installation sites and by ensuring minimal maintenance with zero lamp failures during the trial period. Another satisfied customer is Pattonair, a global aerospace and defence supply chain provider who has reduced its lighting energy costs by 40% following the installation of low energy, high performance G5 LED Battens from the Goodlight range, replacing outdated, energy hungry fluorescent tubes within the aerospace’s warehouse, inspection and kitting areas. The installation has

directly resulted in a 40% reduction in kilowatt hours which is spot on target with their original forecast.

SUPERIOR LIGHT QUALITY LEDs have a better quality of light distribution and focus light in a specific direction as opposed to fluorescent lighting that spreads the light more spherically. Goodlight LED lighting provides directional light that gives optimum visibility that is glare and flicker-free. In aviation and aerospace environments where long operating hours are the norm, high lighting levels are crucial not only to enhance employee performance, but for the overall safety and efficiency in the workplace. Poor lighting increases the risk of errors and accidents, which in the aviation industry, is not an option. Middlesex Aerospace, a leader and strategic manufacturer of aerospace engineering components, was thrilled with achieving up to 80% energy savings and the improved working conditions in the production factory and inspection area at its manufacturing site in Hampshire after upgrading to Goodlight GX1 LED High Bays. John Masey, Senior Buyer at Middlesex Aerospace said, “Since the

installation, we have been very impressed with the light quality which is evenly distributed over the factory floor. The new Goodlight LED lighting is flicker-free, therefore reducing eye strain, has low UV emissions and promotes performance amongst our staff, greatly improving the working environment. In addition, we are making substantial energy savings and have eliminated maintenance costs.”

SAFETY AND SECURITY Passenger safety and security is a high priority for any airport and lighting has a crucial role to play. An efficient lighting system can mirror natural daylight during hours of darkness to fit with the 24/7 nature of many busy airports such as Heathrow and illuminate accessed areas, for example walkways and car parks. Eliminating pockets of darkness with a robust LED lighting system will give passengers greater peace of mind and a better overall customer journey. Organisations are able to fund lighting replacement programmes from their operating budgets by taking advantage of Goodlight’s Bright Plan LED leasing scheme. This allows the replacement lights to be paid for directly by the energy savings and the customer will own the lights outright

at the end of the lease. Goodlight offers businesses a free site survey which will provide a detailed breakdown of suitable replacement light fittings, the installed cost and the return on investment from savings on energy and maintenance costs. They also guarantee all Goodlight LED lighting for five years, making installation risk-free.

CONCLUSION As shown in the case studies above, upgrading to LED lighting has seen businesses reap the rewards of immediate energy savings, enhanced working conditions and customer satisfaction. With products such as the award-winning Goodlight range of LED lamps and luminaires, airports and manufacturing sites can all benefit from reliable, long life, maintenance free LED lighting that enhances its environment and improves security and safety for all. www.goodlight.co.uk

MONITORING & METERING

THE STREAMLINED ENERGY CARBON REPORTING SCHEME (SECR) IS HERE For some time now, the UK has been on a mission to become a low-carbon nation. It all started with the Intergovernmental Panel on climate change in 1988, and was further reinforced with the United Nations Framework Convention on climate change, established in 1992. As part of its latest strategy, the Government has now announced plans for the new Streamlined Energy and Carbon Reporting (SECR) regulations which take effect in 2019. Julian Grant from Chauvin-Arnoux UK looks at the new regulation to see which businesses it will affect and what it will involve for them. 24

T

he new mandatory reporting framework will replace the CRC Energy Efficiency Scheme (CRC EES), and extend the scope of the existing Mandatory Carbon Reporting (MCR) regulations to include all large organisations. It aims to use energy efficiency as a mechanism to help increase business productivity, and in doing so will also improve the security of energy supplies, as the goal is to reduce current demand by at least 20 per cent before 2030. As the name suggests, the SECR is designed to streamline and reduce complexity in the carbon and energy reporting landscape, as well as broaden the scope for reporting compliance. It is aimed at companies with at least 250 employees or an annual turnover greater than £36m, as well as an annual balance sheet greater than £18m. The number of companies reporting into the SECR will also include those in the

ENERGY MANAGER MAGAZINE • NOVEMBER/DECEMBER 2018

Energy Saving Opportunities Scheme (ESOS), increasing the number of businesses involved from 1,200 to about 12,000. If a business meets the criteria it will be automatically entered into the scheme and the energy use, carbon emissions, and energy efficiency actions of the business will be made publicly available, alongside some reference comparison metrics. For businesses that haven’t already thought about increasing their energy efficiency, adherence to SECR will involve additional costs in administration and possible equipment purchase. However, if the quoted 20 per cent improvements in energy efficiency can be achieved, any costs will be more than covered. Companies should embrace an energy management system that encompasses people, processes, and technology, and go back to the basics of energy management by analysing their operations, to understand the meaningful and sustainable changes that can be made. Many forward-thinking businesses have, of course, already been doing this in


recent years by using Power and Energy loggers (PELs) to monitor energy use around their facilities. Based on Carbon Trust statistics that 20% of energy is wasted on inefficient equipment, and with British Gas SME smart meter surveys suggesting 46% of energy use is out of hours, use of PELs to identify such things is an obvious thing to do. In addition to this, everybody in the business needs to be involved and new initiatives need the support of senior management. Without staff ownership and management support energy management improvements will likely dwindle. An effective energy policy should be written for the business that should detail the commitment, set objectives, define targets, detail plans, indicate responsibilities, as well as ensuring compliance and continuous improvement. Assessment of energy performance by examination of past and present energy consumption in order to establish benchmarks should take place, enabling an understanding of energy use patterns and trends. Conducting energy audits will help identify areas of potential energy savings within your organisation. Encouraging staff to act in an “energy efficient” manner, thinking about their energy use, streamlining

processes and installing energy efficient technology, setting realistic targets and timescales, prioritising activities, and making sure they all get done, should be top of the agenda. Most of all it is important to measure and communicate the benefits. The results of projects should be communicated to staff to maintain motivation, and to senior management to ensure continued “buy in”. It might make justifying capital expenditure easier in future if the

implemented energy projects have a proven record of delivering savings. Energy efficiency is beneficial to everybody as it removes unnecessary costs from businesses thus improving financial efficiency. And if every business does its part the UK could soon become the low-carbon nation it needs to be to remain competitive on the world stage, and at the same time do its bit to help reduce climate change. www.chauvin-arnoux.co.uk

METERING & MONITORING – THE TECHNOLOGY DIVIDEND

26

HOW MUCH TECHNOLOGY DO YOU NEED TO DO ENERGY MANAGEMENT? AND HOW MUCH DATA?

Elcomponent chairman Bill Gysin looks at the impact of technology on Sub-metering hardware and software

Actually not much of either… Applying tried and tested EM routines using daily (or even weekly or monthly) manual reads of whatever meters are available, along with the relevant driver data – production, degree-days or whatever – in a well-known spreadsheet will deliver savings with little or no outlay on hardware and using software tools that mostly are available already. But… this lack of technology and the relative paucity of data has to be balanced by an excess of time, which is of course otherwise known as ‘money’, effort and not a little skill. After all, those meters are not going to read themselves and good as your favourite spreadsheet may be, it does not populate itself or create the necessary formulae to carry out a regression analysis without some external intervention. And of course there are physical limits to this purely

manual approach which is why Automatic Meter Reading (AMR) systems and Monitoring & Targeting software (M&T) are considered essential by most large businesses and more than a few SMEs. The drivers for this are not simply better and easier Energy Management – the requirements of ESOS Phase II and ISO50001 (which is perhaps the ultimate way to deal with ESOS) are much harder to meet, if indeed they can be met at all, without sub-metering linked to AMR. The need to raise awareness and highlight the role of the individual in the achievement of the ‘continuous improvement’ that is mandated by 50001 but is in any case part of every energy manager’s goals is far easier if relevant and targeted energy performance dashboards are strategically placed around the organisation, and just a mouse-click away for all stakeholders. The operation

ENERGY MANAGER MAGAZINE • NOVEMBER/DECEMBER 2018

publication of energy league tables and the dissemination of energy performance information (hopefully positive) are functions which whilst not impossible, are daunting to say the least without some technology to help out. And there’s no doubt – advances in both hardware and software functionality in as short a period as the last couple of years have added to the capability of, and reduced the installed cost of meter-based Energy Management packages, which is no more than we all expect. The level of technology that we all carry around with us, the sheer connectivity delivered by the Internet of Things and the increasing sophistication of data streaming services has not surprisingly raised our expectations somewhat. These days we see AMR systems that ‘just work’ and M&T software that provides performance rather than simply consumption data as


MONITORING & METERING no big deal. And so we should. Suppliers in the space occupied by Elcomponent can ill-afford to let the grass grow around them or they risk today’s ‘cutting edge’ becoming tomorrow’s ‘legacy’. However, a note of caution is appropriate. In this sector clever technology has to mean more than high frequency interval data and dynamic chart rendering. The machinery may have changed but the basic tenets of energy management have not, they have merely been augmented, and a modern sub-metering system still has to tick the boxes that have always mattered and a few more besides.

DATA QUALITY AND RELIABILITY REMAIN PARAMOUNT – CLEVER HARDWARE THAT ONLY WORKS SOME OF THE TIME HAS ITS DRAWBACKS… A friendly and accessible userinterface is more important than ever. Tools that are easy to use get used, the rest tend to stay in the box… Consumption data on its own only gets you so far – yes there is and always

has been a great deal valuable saving to be made using nothing more than a half-hour bar chart and a mk1 eyeball, but automatic normalisation of usage against key drivers and preferably a presentation of ‘actual against expected’ consumption is essential if energy is truly to be managed. Concise and effective reporting – both scheduled and event triggered – is another must-have if the system is to pay its way in maintaining the improvements it helped to deliver in the first place. Space restrictions preclude a more exhaustive list, but the message is clear. Technology allows us easily to read remote or awkwardly sited meters that would have been expensive and difficult to connect a few years ago. It allows us to transmit huge amounts of data regardless of available infrastructure, and the cloud delivers almost unlimited storage and access facilities. We can check almost any

aspect of a system on a mobile phone or tablet in real time and the universal availability of web-based software means we can all be energy managers if we wish. But… if the data acquisition isn’t solid, or the software only keeps track of consumption and not performance, or our alarms and reports don’t arrive when they should or don’t contain the right information, then we have technology for its own sake rather than as a contributor to a better metering and monitoring package. www.elcomponent.co.uk

IMSERV FIRST NON-DOMESTIC METERING BUSINESS IN THE UK TO RECEIVE OU ACCREDITATION FOR SMART METERS

I

MServ, one of the UK’s leading Energy Data Collection and Meter Operations service providers, is the first nondomestic metering business to become a user of DCC services in the Other User (OU) role for smart meters. The OU role is designed to allow users to request information from Smart Meters on behalf of consumers, with appropriate consent, to perform the following services: • Retrieve half-hourly data via the DCC from smart meters; • Install and pair into the Smart Metering Home Area Network a Consumer Access Device (CAD) at site to enable real-time access to smart meter data from both an electricity and gas smart meters including pricing, instantaneous and cumulative consumption information.

IMServ can now act on behalf of end user customers and parties working with them such as: TPIs, Brokers, BMS providers, system integrators, and price comparison websites to ‘collect’ smart meter data direct from smart meters and/or via the DCC without the need to go to the energy supplier. Using the OU role, IMServ can utilise smart meters to provide: • Half-hourly interval data readings, regardless of the consumer’s procurement deal • Visibility of consumption patterns throughout the day to aid in load-shifting activities • Ability to identify opportunities for energy and cost efficiency from the data • Directly feed into a client’s BMS and other smart devices for dynamic control aligned with the metering data • Deliver data for visibility through dashboards and apps • Enable consumers to run the half-hourly data through price comparison websites Justin Vroone, Commercial Director at IMServ, said: “Securing this coveted accrediation for IMServ is great news for our business and our customers

who can now reap the energy and financial savings that this will bring. “Businesses on monthly ‘read-only’ meters will now have the ability to view their consumption data on a half hourly, rather than monthly basis. The benefit of this being that they will be able to see at which times of day they are consuming the most energy and at what price. The role also allows us to install and connect CAD devices to the smart-meter for direct connection into BMS and IoT systems. This has an immediate benefit for consumers and energy management companies as they can use the real-time data to actively change BMS controls or deliver behavioural change activities within the business to reduce consumption and cost. “Consumers can also use the halfhourly interval data to run through price comparison websites to be easily able to assess whether they’re on the best procurement deal – something that’s difficult with monthly reads.” If anyone is interested in finding out more about the new services that IMServ are looking to offer to the market using the Other User role then please contact IMServ. www.imserv.com

NEW VITOCROSSAL 200 COMMERCIAL BOILER OFFERS MAXIMUM OUTPUT IN A COMPACT, EASY TO INSTALL PACKAGE Viessmann strengthens its commercial boiler offer with the development of an innovative, fully patented, space-saving MatriX disc burner; boiler on display at EMEX 2018

V

iessmann has introduced the new Vitocrossal 200, an 800-1000 kW gas condensing boiler with an innovative MatriX pre-mix disc burner which sets new standards for commercial boilers. The boiler will be launched at the Viessmann stand (D75) at EMEX 2018 on 21-22nd November 2018 at ExCeL in London. The Vitocrossal 200’s numerous improvements over its predecessor include an extended modulation range of 1:6 for greater efficiency at partial load and low NOx emissions of less than 40 mg per kWh, a modular design for easier installation, and significantly smaller dimensions which make it perfectly-suited to smaller plant rooms. For heating larger premises, there is a cascade function for up to eight boilers with a total output of 8,000 kW. The Vitocrossal 200’s footprint is 27% more compact than that of a boiler with a conventional burner. This is because the new disc-shaped MatriX premix gas burner is much flatter than a conventional cylindrical burner, and because advances in burner materials have allowed a shorter flame and smaller combustion chamber. Viessmann has been able to shorten the unit by one metre. The boiler is just 3187 mm or 3389 mm (800 and 1000 kW models), 1060mm wide and 1676mm high. Whereas traditional burners are made of stainless steel, the Vitocrossal 200’s disc burner is constructed of ceramic fibre bound together by a silicone carbide coating to a thickness of approximately 3 mm and welded

together at points of contact. The perforated structure enables very low pressure-drop across the burner material, allowing the combustion blower to be compact. In addition, this 95 percentporous material produces stable combustion and achieves a high output at a low flame temperature, making it possible to employ a smaller burner. The boiler can be operated either room temperature-dependent or room pressure-dependent. For high operational reliability and long service life, the Vitocrossal 200 employs Viessmann’s proven, corrosion-resistant stainless steel InoxCrossal heat exchanger. This enables highly effective heat transfer and a high condensation rate. Efficiency is further enhanced by the boiler having two return connections, so that there can be low- and high-temperature circuits with a lower temperature return for better condensation. In addition to being space-efficient and energy-efficient, the new Vitocrossal 200 is also convenient to install and service. The heat exchanger and burner modules are separable for easier carriage and separate delivery; the front cover is hinged on a gas-pressure spring for easy opening; and the side panels can be quickly removed for unobstructed access to the MatriX disc burner, which can be swung out to the side. For commissioning there is an assistance function on the boiler’s integrated large colour touchdisplay for the Vitotronic control unit.

This boiler can be connected directly to Viessmann’s Vitodata server using proven Vitocom (LAN) interfaces and has integrated WLAN for service interface. This means the operating status of the heating centre is monitored around-the-clock and if a fault occurs the boiler will send a message to the engineer’s smartphone. Viessmann’s commercial sales director, Jon Grist said: “The new Vitocrossal 200 represents a significant step forward in commercial boilers because of its compactness. Large industrial plant-rooms are going out of favour, being replaced by multiple boiler rooms, and the Vitocrossal 200 is perfect for those smaller spaces. This boiler is also desirable for its low NOx emissions, lower minimum output with higher efficiency, and easier handling and serviceability. We are expecting high levels of interest from consultants and specifiers who work with large contractors on projects such as hospitals and district heating systems.” www.viessmann.co.uk

STOKVIS PERFORMANCE IN STEP WITH LONDON’S ‘CLEANER HEAT CASHBACK’ SCHEME

B

usiness owners and facilities managers should move quickly to take advantage of funding for replacement boilers under the Mayor of London’s Cleaner Heat Cashback scheme, a major boiler company has urged. Paul Sands of Stokvis Energy Systems is alerting specifiers to the fact that the £10million energy saving initiative – launched by Sadiq Khan in July – will close for applications on 31 March 2020, or as soon as the money runs out. Small to medium sized businesses, or SMEs who currently run boilers that are more than ten years old can claim up to 40% cashback when they install a new, more efficient model. Crucially, the scheme is seeking to not only reduce greenhouse gases, but also nitrous oxide or NOx emissions, which is why the Stokvis EVOLUTION ranges of fully modulating boilers are ideally suited to the scheme. Pauls Sands commented: “Business premises currently account for 40% of the capital’s greenhouse gas emissions, and some 7% of NOx and as other clean air initiatives, such as targeting the most polluting cars and commercial vehicles, take effect, those percentages are set to become more significant. “Our R40 and R600 EVOLUTION boilers are ideal replacement options, not only offering very high, fully modulating efficiency and best in class NOx emissions, but also being physically well suited to replacement situations. “Unlike many other commercial boilers on the market, the EVOLUTION units are basically compact, and the R600 can also be dismantled to make it easier to manoeuvre through narrow doorways or down into basement plant rooms. I would urge London’s business owners and facilities managers to waste no time in taking advantage of this generous cashback scheme.” Shirley Rodrigues, Deputy Mayor for Environment & Energy, confirmed: “There are thousands of small businesses in London who have older boilers and this hugely innovative scheme not only helps them to save money, but

30

it also reduces carbon emissions and improves the capital’s air quality. “Businesses could save hundreds of pounds a year on energy bills by switching from an older, inefficient boiler or heating system – and this is exactly the kind of initiative that will help us achieve the Mayor’s ambition of making London a zero-carbon city by 2050. Tackling London’s filthy air is one of the Mayor’s top priorities and this is just the latest in a package of measures that he has introduced to improve the quality of the air we breathe.”¹ The R40 EVOLUTION range encompasses six models delivering between 56kW and 138kW output; spanning the scheme’s 70kW minimum figure - while for larger commercial requirements, modules can be linked along a wall or backto-back to form a Modupak solution, delivering capacities up to 1,102kW. The ultra-high efficiency of the R40 EVOLUTION boiler derives from the

ENERGY MANAGER MAGAZINE • NOVEMBER/DECEMBER 2018

single or double-helix heat exchanger (dependent on model), which not only uses low water volume, but reduces hydraulic resistance and thereby the electrical consumption of the pump. Additionally, being made from high grade 316 austenitic stainless steel ensures longevity for the heat exchanger, as well as greatly improved reliability. Furthermore, Stokvis utilises robotic laser welding techniques to join the exchanger tube and fins, ensuring the highest possible heat transfer. All of this attention to detail results in a Seasonal Space Heating Efficiency for the Stokvis EVOLUTION boiler measured at an impressive 92.5%. Then under EN15502. R40 EVOLUTION boilers offer a very clean NOx Class 6 rating with readings starting as low as 22 mg/KWh; while CO2 levels are between 8.2 and 9%.

GOING SOFT ON WATER TREATMENT According to Rinnai UK, leader in continuous flow gas water heating products, stored hot water systems suffer badly from the problem of scale build up – even when water treatment measures are in place.

L

ime scale consists of calcium carbonate (calcite) with lesser amounts of other calcium salts such as sulphate. Sometimes lime scale deposits contain corrosion debris and this scale buildup can affect the water heaters by reducing their efficiency and overall performance. Ultimately, ongoing use with hard water will shorten the lifespan of water heating appliances. Limescale build up is a serious problem in Southern England, Wessex, Wales, Hull and the Thames area. In these hard water areas especially scaling in stored hot water systems ultimately leads to lower performance, breakdown, and expensive remedial treatment such as power flushing and in the worst scenario cracked cylinders. Serious money needs then to be spent to get the system back to work; all of which means downtime, inconvenience and, for many businesses a detrimental impact on income, customer satisfaction and performance. Basically, there are three types of water treatment available for the management of scale. The first, a calcium softener, physically takes calcium out of the water and exchanges it for sodium. The second type is a physical electro-magnetic device that clips around pipe work and encourages the scale to ‘go with the flow’ rather than attach itself to the cylinder. Sodium water softeners are effective but have two drawbacks – the water is not potable - and they rely on people to put salt in them, thereby allowing a possibility of human error. One of the most common reasons for engineers to be called out is because ‘the water softener has stopped working’. 99 times out of a 100 this is only because the operator has forgotten or omitted

to add salt to the water conditioner. The third solution, zinc-based inhibitors, is the only type recommended by Rinnai for use with its appliances. This technology uses electrochemical dispersement to impart a precise amount of soluble zinc which interferes with the crystallisation process of scale build up. The use of water softeners and scale inhibitors can go a long way towards alleviating the problem but with stored hot water systems, apart from calcium water softeners if, after passing through the conditioner, hot water is subsequently stored in a cylinder then after 24 hours the process is reversed and scale begins to build up again. On top of this, any serious turbulence can affect performance and scale up the heat exchanger – ie where there are tight bends in the system. Continuous flow water systems are the easiest system to keep scale free. Even where a ‘turnkey pack’ system such as the Rinnai Infinity Plus Storage is fitted and a booster tank added the water is unlikely to be held for 24 hours. These systems are commonly used in hotels, for example, to deal with peak demand times and because they recover in minutes due to the Rinnai unit’s efficiency, scale is never likely to be a problem. To be additionally sure limescale is never a problem, Rinnai heaters also incorporate a scale warning device that continually monitors the appliances for

lime scale deposits around the heat exchanger. Once lime scale build-up is identified, a message is sent to the built-in interface panel on the front of the appliance to alert the end user that it is time to call a Rinnai service agent to perform a lime scale flush. For a ‘belt and braces’ solution a continuous flow system, combined with zinc-based treatment means end users can virtually say goodbye to scaling. For the sake of a small cash outlay, a zinc conditioner is a useful safeguard and one that will give end users additional peace of mind. Unlike calcium water softeners, zinc treatments need a lot less attention and could be simply built into the maintenance contract, thereby keeping costs down.

DISTRICT HEATING NETWORK DESIGNS FOR GREATER ENERGY EFFICIENCY AT WEMBLEY PARK Crispin Matson, Director, Ramboll

I

nstalling energy solutions that are not only efficient, but are also environmentally friendly, is becoming a priority across building developments within the UK. District heating networks have become more popular than ever before, especially in cities where buildings are far more densely populated. District heating is a unique solution that provides heating a number of houses or buildings form one central energy source. Using a singular source of energy removes the need for individual gas boilers, and provides a far more efficient and economically friendly solution that also reduces carbon emissions. The Wembley Park regeneration project is the UK’s largest Build-To-Rent development to date, providing over 5,500 new homes along with commercial spaces in an 85-acre complex around Wembley Stadium. In May 2016, we were approached by Quintain to help with the design and delivery of a district heating network to serve the new development – one of the largest district heating networks in London. The regeneration project was designed to offer residents accommodation for rent by paying an all-inclusive charge, including all utility bills, within a single monthly payment. The original planning permission outlined the development of two separate district heating networks across the site, each connected to approximately 20 separate buildings. However, an indepth review from the design team led to these two networks being merged into one network with a single energy centre. Located underneath the residential tower of the largest development, the energy centre contains the main heat generating equipment: gas fired Combined Heat and Power (CHP) plant and gas fired boilers, and the primary distribution pumps.

32

We used energy analysis software to gain detailed data for the predicted energy demand, which allowed for the calculation of the optimum size of the CHP plant to work in conjunction with the optimum size of thermal stores. The CHP plant was able to achieve the maximum carbon savings by producing both heat, which is fed into the district heating network, and electricity, which is fed back directly into the electricity grid. The optimum size of the CHP was calculated to be 2 No 1.5 MWe gas fired engines, and the corresponding thermal store size was calculated to be 150m3. This was achieved by installing 2 No 75m3 tanks each 4 metres in diameter and 7 metres high. 3 No gas fired boilers (rated at 9MW capacity) provide additional heating capacity for peak and standby scenarios. The district heating pipework network connects 20 separate individual buildings, through one main energy centre. The network route is approximately 2.5km in length, spanning across the site to buildings on three sides of the existing Wembley Football Stadium. Through the use of ‘System Rornet’ hydraulic analysis software, we were able to augment the district heating pipework size and determine the size of the most economical circulation pumps. The final route of the district heating

ENERGY MANAGER MAGAZINE • NOVEMBER/DECEMBER 2018

pipework threads in a complex pattern which has been coordinated to avoid the multitude of other existing and new utility services (including, but not limited to, power cables, telecommunications services and gas services), stretching across both public and private land in the area. We were tasked with producing detailed pipework drawings to enable the installation of the pipework in independent construction phases. Therefore, the heating network could be installed during periods in the programme where there was greater access to the site, depending on the stadiums event schedule. Common practice for district heating networks within the UK is to connect the network into an individual building block from a secondary heat exchange substation, typically located in the basement. From there, a secondary heating distribution system feeds into Heat Interfaces Units (HIUs), located in each individual apartment. However, given that the Wembley Park flats were to be rented rather than sold, it was decided that the HIUs were to be omitted. Instead, centralised heating and water systems would be installed in each building, feeding into the apartment separately. This meant the site would be able to benefit from a reduction in capital costs


HEATING

PUTTING STEAM EFFICIENCY IN THE DRIVING SEAT and an increasingly energy efficient heating system, as a result of lower district heating return temperatures from the omission of an additional heat exchanger, typically located within HIUs. Within each building the two separate circuits were connected by two distinct heat exchangers – one for the buildings’ centralised heating circuit, and one for the centralised hot water system. Both heat exchangers are uniquely integrated into a single building substation to maximise their thermal efficiency by utilising the return water from the secondary radiator heating circuit’s heat exchanger to preheat the cold-water feed for the hot water domestic use. This allows the return water temperature of the dh network to be kept to an absolute minimum, which reduces the amount of heat that is lost through the network. The project presented a number of unique challenges. The space that was allocated to the energy centre was predetermined, which made the designing process for the complex pipework route all the more difficult. In addition, working within a phased construction plan limited how much work could be completed at any given time. However, we were able to overcome these challenges by completing design work using software that could account for these issues, and by integrating heat exchangers in a unique manner. The network and the associated energy centre are now in construction, whilst the majority of the pipework has already been installed. The installation of the energy centre is also rapidly progressing. The initial installation included the thermal stores, whilst the other major items of equipment, including the CHPs, boiler and pumps, are due to be installed later this year. The plan is to have the entire district heating network installed and running by late summer 2019. The project adds thousands of houses to the growing district heating network. District heating networks could be set to become the norm for new large-scale residential developments. www.ramboll.com

With the ever-increasing pressure to improve energy efficiency in the UK, car manufacturers are leading by example. Plant Oxford – the production site for iconic car brand MINI – has undergone significant development over the years. In a bid to improve energy efficiency across the site, steam specialist Spirax Sarco was called upon to transform its current hot water generation system and deliver enhanced operational and energy savings.

T

he Oxford facility has been established since 1913, initially producing the two-seater Morris vehicle, but it was in 1959 when the first Mini rolled off the production line. Today, MINI is part of the BMW Group and many of the variants are built in its factory in Oxford. One area that has benefited from modernisation is the site’s steam-tohot-water heating system. Spirax Sarco’s team of steam experts were asked to review the existing installation. Tasked with optimising efficiency and reducing costs, Angelo Giambrone, Business Development Manager at Spirax Sarco, played a key role in the project.

GETTING INTO GEAR “The existing installation comprised of three large shell and tube calorifiers. Traditionally calorifiers were a popular way to deliver hot water but in recent years there has been a great deal of development with steamto-hot-water systems which has helped to improve efficiency and safety,” says Angelo. “The old units were mounted at high level, which made maintenance a consistent challenge. This was particularly evident when the units underwent insurance inspections.”

NAVIGATING SPACE “The best course of action was to completely remove the three large calorifiers. As with many facilities, space is a premium and the new solution needed to fit into a much more convenient location. We replaced the old units with high efficiency EasiHeat™ systems which use the latest in plate heat exchange technology,” comments Angelo. “As each EasiHeat™ is a pre-fabricated package,

it meant that installation was simple. The smaller footprint has allowed the new units to be sited in a practical location at ground level. They’re also not subject to the same strip-down pressure testing as the shell and tube systems, which helps deliver operational and maintenance savings too,” says Angelo.

DRIVING DOWN COSTS Each of the EasiHeat™ packages come equipped with a stand-alone PLC Energy Management System, which has provided Plant Oxford with much improved temperature control. “The control system helps to utilise all of the useful energy available in the steam, which in turn reduces fuel demand and associated CO2 emissions. This essentially means that the savings achieved are now contributing to the overall system efficiency. “Removing the old calorifiers was a major decision for the business but by doing so the site has benefited from improved safety and reduced maintenance. Plant Oxford is now able to provide consistent low temperature hot water to their heating system using modern heat exchange technology to deliver it efficiently and safely.” To learn more about Spirax Sarco EasiHeat™, please visit: http://www.spiraxsarco.com/global/uk/ Products/Pages/EasiHeat.aspx

ELECTROSERV+ INTRODUCES INNOVATIVE WIRELESS TEMPERATURE CONTROLLING SYSTEM TO THE UK

E

lectroserv+ Temperature, Controls and Sensors has introduced an innovative product to the UK which will provide an effective solution to industrial process monitoring. The composite industry will benefit massively from this effective new product which brings a safe and forward thinking solution to temperature control systems. A wireless temperature sensor which can sit in temperatures as low as -60°C and as high as 80°C, removes the need to have potentially dangerous wires laying around and offers flexibility in its use. The costeffective transmitters handle the most demanding applications and integrate into existing process control systems. Simon Fisher, director at Electroserv+ commented: “This technology is new to the UK, but it is the next logical and innovative step for Industrial Process Monitoring systems. This is a great replacement for traditional cabling which is expensive, time consuming and is always at risk of being cut. The wireless temperature sensors are a great example of Industry 4.0 and how it is moving forward. “Factories have changed,

34

machines aren’t just built and kept in place anymore. Machinery moves around now and there is a need for different areas of the factory to see information from another area. This new technology enables that to happen and allows for flexibility.” Electroserv+ has already installed a wireless temperature sensor within two large UK companies to enable high quality process controlling throughout various industries. Meggitt, a manufacturer for the nose cones on Eurofighters, needed to find a way to measure the temperature of a polymer composite all the way through the manufacturing process. The raw materials start in the freezer and a system needed to be implemented which would raise an alarm if it went above a certain temperature. A wireless temperature sensor from Electroserv+ was a fantastic solution due to its durability in freezing cold climates. Originally, Meggitt had a wired solution but it meant nothing was being recorded. To wire the system across the factory was too cost prohibitive and it would include wiring across roads, so it wasn’t achievable. Some of the containers also had to be moved around which wouldn’t

ENERGY MANAGER MAGAZINE • NOVEMBER/DECEMBER 2018

be possible if they were attached to wires. By implementing a Electroserv+ device, the traceability probe, which sits inside the role of composite, sends information back to the Central Eurotherm Data Acquisition. As it is wireless it is also able to sit within the equipment and containers as they are moved around. Simon added: “The wireless temperature sensor was a fantastic solution for Meggitt. Removing the need for wiring means it is flexible and it can be used throughout the whole process offering a practical solution to the entire factory’s production line.” A spokesperson from Meggitt said: “The new wireless temperature sensor is exceptional. It is imperative we accurately measure the temperature of our polymer composite from beginning to end of the process. “Before we invested in the Electroserv+ device we had no way of recording the data and Electroserv+ has provided us with an innovative solution which also allows us the flexibility of moving the equipment around.” To see the control and measurement sensors which are available visit: electroserv.co.uk

RINNAI DELIVERS HOT WATER TO AWARD WINNING LAKELAND HOLIDAY PARK REFURB

R

innai’s continuous flow gas fired water heating units have been installed at the award winning Hillcroft Park which is set in the beautiful Ullswater Valley and offers year-round holiday accommodation to suit every taste and pocket. Hillcroft Park sits at the head of Ullswater above the pretty lakeside village of Pooley Bridge and offers traditional camping, camping pods, luxury lodges and holiday homes. Recently the site, owned operated by the Heath family, added a new visitor pavilion and shower block to add to the existing facilities. Five Rinnai 1200i continuous flow units were installed as a cascade design so that any peak demand can be easily met – the 1200i delivers up to 35 litres of useable hot water per minute. The whole system is powered by LPG. All Rinnai units used in sites which are ‘off grid’ of the mains gas supply are supplied to site LPG ready enabled. The hot water delivery system at Hillcroft Park incorporates a secondary return utilising Rinnai pure controls and common flue headers on the units to streamline the flue configuration. The site is based on sustainability and energy savings so electronic sequencing is employed on the system. These smart sequencing controls will optimise system performance by only firing additional units when more outlets are opened meaning the site only uses energy when it is needed. Hillcroft Park has won many awards – notably the David Bellamy Conservation Award – several years running. This honour is awarded to those sites which met and exceed a variety of criteria – Managing their land as a haven for wildlife; Reduce their use of energy, water and other resources; Reduce, reuse and recycle the waste they produce and support their local communities. The site is also no strange to celebrities – earlier this year the much-loved comedian, Johnny Vegas returned to Hillcroft Park to open the impressive, new facilities block. Hillcroft Park became Johnny’s Lakeland ‘Home from Home’ for six weeks in 2017 during filming for the BBC series ‘Home from Home’ which appeared on BBC1.

Johnny opened the brand-new facilities building including a shower block that must be one of the most impressive in the UK when it comes to camping bathing facilities. Many of the fixtures and fittings would not be amiss in a luxury bathroom. Not content with high quality showers, basins, taps and tiles – campers also enjoy panoramic Lakeland scenes thoughtfully installed within the facilities themselves as well as a custom-made Lakeland soundscape of dawn chorus, sheep and, of course, water. At Hillcroft Park, life takes on a slower pace – a throwback to those carefree, childhood holidays. While you can connect to the world wide web while you’re with us, we’d encourage you to ditch the digital, disconnect and discover simpler pleasures like a walk up the fell, a dip in the lake followed by a family feast or a quiet pint and a breath-taking sunset to the sound of birdsong. The Rinnai HDC 1200i water heater unit uses heat exchanger technology to allow high capacity from mains pressure, thereby guaranteeing all the hot water needed, when it is needed on demand. As well as high capacities, the Rinnai unit has lower greenhouse emissions because of the new reduced NOx burner technology. Available in both internal and external versions, HDC1200i gives end users 7% net efficiency* because the condensing process delivers up to 97% thermal efficiency, translating to significant energy savings when compared to standard tankless water heaters. All of which makes the HDC1200i continuous flow hot water system by far the best option for all types of sites. “The only time you are using energy is when there is a demand, * Tested and certificated by Technigas to EN 26.

in other words it is only burning gas when a tap or shower is being run and, design improvements by Rinnai have increased heat efficiency of its hot-water appliances from 80% to 95%, while decreasing gas consumption by around 14%,” says Gerard Gulliver for Rinnai. The HDC1200i is also renewablesready (suitable for use as a temperature booster for solar thermal and heatpump) and can be easily configured in a manifold arrangement, ensuring they will never run out of hot water whatever the demand. As long as electricity, water, and gas supplies are connected, hot water is available when the hot water taps are open. A DIP switch enables pin-point temperature setting and for safety, the over-temperature protection will switch off the heater should the water temperature exceed by 3°C above its set-point. www.rinnaiuk.com

DRIVING THE FUTURE

ELECTRIC VEHICLES: HOW DO WE MOVE TO FULL SCALE DEPLOYMENT?

E

lectric vehicles (EVs) are said to cost 23% less to service and maintain than petrol models over three years/60,000 miles. Yet, there are still key hurdles to overcome before we can move to a full-scale deployment of EVs.

Building out an infrastructure based on common standards with appropriate coverage in and outside cities, using one payment method open to all Commonality of Infrastructure is a real issue for the success of EVs and this needs to be addressed to facilitate a widespread EV rollout. The need for commonality captures charging points and the associated cabling, as well as the overarching payment systems used to pay for charging and process data. The current payment problem, which requires an EV driver to use multiple applications to charge a vehicle across the country, cannot be solved by simply paying for charging by way of contactless card payment, since this does not allow for recovery of VAT receipts, fleet charging and the collection of data from charge points. A charging solution should therefore address these areas. There is a need for a new infrastructure model to be rolled out and it is very difficult to make money from simply installing a charging point and making it available. Charging and the associated technologies will become a commodity product as uptake develops, but there is a need to look for other sources of revenue to make a model of this type work. We are seeing supermarkets installing charging points as part of a wider customer programme, which incentivises maximising time in store. There are also opportunities arising from re-thinking how we use infrastructure and monetising periods of downtime, for example, query whether commercial fleet/mass transport fleet charging only needed for part of day (such as overnight) meaning charging infrastructure in commercial premises (such as offices) could be put to other uses to bolster the commercial model. A further possible future development which would maximise revenues available from charging infrastructure is fitting charging

36

points with solar panels and battery storage. This would enable the charging point to self-power using renewables and to undertake price arbitrage via the battery, thereby bolstering revenues for the charging point operator. Consideration was given to where infrastructure is being developed already. We are seeing activity at the local authority level, made easier by the provision of grant funding. However, the uptake and activity is rather fragmented at present and uptake operates on a “postcode lottery” basis. We are also seeing activity in the bus fleet space, particularly in London, where much work has gone into the replacement of bus fleets, or retro-fitting with low emission technology. Buses are somewhat of a “closed system” comparatively to the broader car market.

Managing peak consumption issues through the adoption of smart charging and vehicleto-grid (V2G) technologies The electricity network presents issues around capacity - the grid is

ENERGY MANAGER MAGAZINE • NOVEMBER/DECEMBER 2018

currently constrained in many areas and it is difficult to obtain grid capacity for the addition of charging infrastructure without being required to meet the cost and time delay of reinforcement works. The cost of grid connections, particularly when coupled with grid reinforcement costs, present a significant problem for installers of connection points. The London Plan further exacerbates this issue through its onerous requirements around level of charging infrastructure required, which at this stage requires developments to incur higher costs to obtain greater capacity for EV charging points than project EV usage patterns will require. The way to deal with the grid issue is to invest progressively over time. Meeting peak demand currently presents a difficult issue for operators


DRIVING THE FUTURE of the electricity network. However, models being looked at by the energy industry as part of a wider move to decentralised energy production and smart networks may assist resolving this issue, at least for the medium term. The use of solar panels and batteries (including re-used batteries) on charge points, together with peer to peer trading mechanisms, vehicle to grid, time of use tariffs, peak load management and demand turn down are important structures for relieving stress on the network as a result of the increased pressure the EV revolution presents. Debate rages in the industry as to the extent to which grid reinforcement is required to facilitate a mass adoption of EVs. Whilst the grid is currently being treated as critical infrastructure on a national level, we need to re-think our approach to it to make EV’s work, and start approaching our system as a network self-sustained communities, as we are already seeing happening on a localised basis. This will enable balance locally and nationally. To facilitate this, we need greater collaboration in relation to the significant technology already existing. Consideration now needs to be given to what customers actually need and therefore where returns are.

Changing consumer and commercial driver attitudes, behaviours and habits to engage properly with EVs The evangelists have been at the vanguard of the EV industry to date and a transition to the wider early

adopter market segment is imminent. Whilst of those at the table, only two or three currently owned an EV, three quarters of attendees indicated that the next car they will buy will be an EV. A key determinant of EV success in the wider market will be price and it is unlikely that there will be a mass adoption of EVs until we reach price parity with internal combustion engine (“ICE”) models, or the upfront cost of an EV being lower than of an ICE vehicle. This could occur through reduced battery costs, which the table felt was likely to occur overtime, or through the increase of fossil fuel prices or potential taxation, which drive running costs of the ICE

model higher. In where EVs are strong, such as Norway, the upfront cost of an EV is around 50% lower than the UK. Consumer perceptions and the myths surrounding EVs, particularly battery degradation and range anxiety need surmounting to enable the EV market segment to widen. There is a need for the positive reinforcement of messaging through existing EV users and early adopters, so wider messaging starts to filter through to the mass market. There is also a need for dealers to proactively sell EVs, rather than favouring traditional models due to availability. www.osborneclarke.com

UK POWER NETWORKS SERVICES DEPLOY ELECTRIC VEHICLES AT LONDON AIRPORTS

U

K Power Networks Services has introduced the first electric vehicles (EVs) and charge points into its fleet at Heathrow, Gatwick and Stansted Airport depots, and EV charge points at its London City Airport depot. This follows the announcement that UK Power Networks is trialling eight electric Renault Kangoo vans in its operational fleet, to be powered by onsite solar generation at six locations, to improve air quality for future generations. Through the introduction of electric vehicles into the UK Power Networks Services fleet, the company will help the airports reduce their overall carbon emissions and support them in achieving their sustainability ambitions. UK Power Networks Services

introduced EVs to its fleet following employee and client feedback. Russell Austin from the company’s Heathrow depot said: “It’s important to start using EVs around the airport to save money and reduce air pollution. As a substation inspector who drives around the airport, I’m proud to be able to say that I’m helping to reduce carbon emissions.” The company will also use the insight from the trial to help airports and other fleet operators build their EV strategy and business case to deploy electric vehicles into their fleets. UK Power Networks Services also recently implemented a smart electric vehicle charging system to enable delivery firm UPS to increase the number of 7.5-tonne electric trucks operating from

DRIVING THE FUTURE

BUSES – NOW HERE’S THE GOOD NEWS By Stephen Joseph

T

o the extent that there is any media coverage of buses, it tends to be bad news. The stories are about cuts in services leaving people isolated, declining use and fares increases. I’ve helped contribute to this over time – when at the Campaign for Better Transport I helped set up a “Save our Buses” campaign, partly to get more attention to the cuts being made in subsidised services, and we succeeded over time (latterly with some help from Jeremy Corbyn quoting our figures at Prime Minister’s Questions). But there are patches of good news about buses too. Some places are seeing growth in bus use, and there are good examples around the country where initiatives and investment by operators, councils or both working together have improved bus services and had more people use them. More of this could happen. The Government has created a £2.4bn “Transforming Cities Fund” to invest in urban transport, especially public transport. The six mayors with combined authorities are getting a four-year allocation without any bidding, linked to population levels; other cities have submitted bids and in September the Prime Minister announced the ten authorities shortlisted. In this week’s Budget the Chancellor extended this fund for a further year and added two more authorities to the shortlist. The National Infrastructure Commission has recommended much more funding for local and urban transport, moving away from the emphasis on inter-urban transport investment. After some years when there has been little funding available for urban transport, there will be a lot of different calls on this money – new railway stations, new tram lines and cycling networks are all being put forward in cities for using this funding. There is a risk that buses – as a less glamorous and more basic mode of transport – get left out. Yet cities ignoring buses would be missing out. A new report from bus campaign group Greener Journeys and the consultancy firm Arup highlights some of the investment projects that

38

have helped buses and sets out several other proposals for further such projects. The variety of current and potential bus investment projects is large. There are familiar ideas like park and ride, but the report gives more emphasis to busways of various kinds – Crawley has created its “Fastway” system linking Horley, Gatwick Airport and Crawley itself by redesigning roundabouts and junctions to give buses priority and create segregated lanes in some places. There is a rapid transit route linking Fareham and Gosport in Hampshire, and a guided busway in Greater Manchester linking Leigh and Ellenbrook. These busways have sped up bus services, made them much more reliable and have attracted people out of cars (in Crawley there is evidence of a decline in car traffic along the busway route). The report highlights proposals for other such busways in Leicester, Milton Keynes, Newcastle and Liverpool, as well as options for using disused railway lines (though these may be more controversial, especially for those now used as cycle routes and greenways). Investment in more behind-thescenes transport operations can help buses too. Several cities have Integrated Traffic Control Centres, and Leeds is planning to develop one, linking all bus operators with those managing the road network. “Selected Vehicle Detection”, as used in Coventry, can give buses priority as they approach traffic lights – a kind of virtual bus lane. There are also ways to reinvent buses. The report looks at Arriva’s “Click” services, an on-demand minibus that uses the latest technology to offer a ride within 20 minutes with an instant booking system. This is already operating in Kent and is now starting in Liverpool and potentially in Sheffield, improving links to employment areas. Low emission “eco buses” are proposed for Liverpool and Bristol. Fares and ticketing are also highlighted in the report, including the Sandwell and Dudley low fare zone, where the operator slashed fares by 35% and bus use increased by over 5%. Exeter is among the cities proposing a single zonal ticket system for all bus services. All of this can be supported by marketing

ENERGY MANAGER MAGAZINE • NOVEMBER/DECEMBER 2018

and promotions, like the Greener Journeys “Catch the Bus Week” and local campaigns like the “Better by Bus” campaign in the Liverpool city-region. These kinds of investments have worked. They have increased bus use, against a background of decline elsewhere, and the report summarises previous work by KPMG and others to show the benefits of this in reducing congestion and pollution and the social and economic benefits such as improving links to employment and training and reduced social isolation. Some will argue that only with a franchised system, where the local transport authority sets routes and fares as in London, will buses truly achieve their potential. That debate is already under way in Manchester and other cities; Steve Rotherham as Mayor of the Liverpool City Region has just launched “the Big Bus Debate” on giving the city-region a world class bus network. However, even a franchised network will work better if given investment and priority over other traffic, and in any case the Transforming Cities Fund is available now. The Greener Journey/Arup report makes a strong case for buses to get their share of this funding and in this way to create more good news stories about buses. Stephen Joseph recently stepped down as Chief Executive of the Campaign for Better Transport. He is now a transport policy consultant. https://greenerjourneys.com/
