Schools strongly support heat decarbonisation, but barriers hinder progress, according to new Baxi research The survey results found: • More than a third of UK schools continue to grapple with key challenges in achieving heating system decarbonisation.

• Technical difficulties, power requirements and funding were among the challenges facing schools upgrading to low carbon heating solutions.

• Despite these issues, 90% of schools report net zero as a key priority, while an additional 99% confirmed that they already have net zero plans in place.

• 93% of school estates managers would likely consider installing a hybrid heat pump system.

A

survey conducted by Baxi of 200 state school estates managers, consultant engineers and M&E contractors has found that while enthusiasm for net zero and support for low carbon heating systems in schools is thriving, persistent barriers remain.

The survey found extremely strong support for net zero within schools, with 90% of estates managers who responded agreeing that net zero is a priority, a sentiment echoed by 78% of consultant engineers and contractors. 99% of the school estates managers surveyed reported having a net zero plan in place.

Experience and satisfaction with low carbon heating systems within schools was also high, with 95% of school estates managers having replaced a fossil fuel boiler with a heat pump in their buildings previously. 97% of all school estates managers (87% of all respondents) viewed heat pump performance and operating costs favourably.

Despite the strong support for low carbon heating and net zero in schools, the study also uncovered significant challenges faced by respondents when opting to install a low carbon heating system. The most prominent was technical difficulty as a barrier to deployment. With 36% and 39% of school estates managers and consultant engineers and contractors respectively identifying the challenge,

there may be a skills gap which can stall decarbonisation projects.

Both groups also agreed that additional electricity capacity needed for low carbon heating solutions was a challenge, with 36% of consultant engineers and contractors outlining this as a barrier to decarbonisation.

School estates managers identified other core challenges, including the financial and technical feasibility of school heating system changes, infrastructure requirements, and the length of project timelines as any major refurbishment projects are typically restricted to the fixed window of time of the summer holiday period.

Additionally, the UK’s electricity pricing is placing a persistent barrier in front of those at the forefront of decarbonising state schools.

The study did identify potential solutions in the form of hybrid heat pump systems and prefabricated packaged solutions. Among Baxi survey respondents, hybrid heat pumps are a popular solution, with a slight preference for this technology over a standalone heat pump system.

80% of the consultant engineers and contractors surveyed would be likely to recommend a hybrid system, and support for hybrids among school estates managers increased with school size. This could be attributed to several factors,

ENERGY MANAGER MAGAZINE • JUNE 2025

including costs, integration with existing hydronic systems, and the shorter installation timeframes required to install a hybrid solution versus converting to a standalone heat pump system.

However, grant support for hybrid heat pump solutions under the Public Sector Decarbonisation Scheme (PSDS) is limited, despite strong backing for the technology.

Policy recommendations Baxi is calling for four clear steps that we believe the Government must take to ramp up the decarbonisation of our state schools and remove barriers preventing the installation of hybrid heating systems within public buildings.

1. Include heating system upgrades for schools within existing public sector support schemes, utilising GB Energy to support 2. Include hybrid heating systems within existing support schemes 3. Address the imbalance in price between gas and electricity 4. Address the skills gap to help deliver clean energy projects.

T

his whitepaper, specifically designed for organisations and busy teams, offers a scientifically grounded yet easily comprehensible overview of the carbon accounting process. Carbon reporting is now a legal requirement for some businesses, particularly in light of expanding international frameworks like the Corporate Sustainability Reporting Directive (CSRD) and the UK’s Streamlined Energy and Carbon Reporting (SECR), highlighting the need for corporations to have the internal capability to measure and manage emissions.

Commenting on the release of the paper, Emily said, “This whitepaper is designed to help organisations understand carbon accounting and realise that they can build this capability internally, with the right training and support.”

Emily outlines the practical advantages of in-house expertise in carbon accounting, including stronger data accuracy, year-on-year consistency

ENERGY MANAGER MAGAZINE • JUNE 2025

and improved stakeholder confidence.

While third-party verification still plays an important role in audit and assurance, Tunley Environmental’s latest whitepaper encourages organisations to build lasting internal capability to manage their emissions and meet long-term climate goals.

The paper also introduces a structured pathway to train key personnel in carbon reporting, a collaborative course designed and delivered in partnership with learning provider Astutis. The course covers everything from identifying emissions sources and applying GHG Protocol standards, to calculating an organisation’s carbon footprint and developing a roadmap to Net Zero. Training is available online or in person and is tailored to both individual learners and corporate teams.

National Grid Electricity Distribution leads the way to a new energy era with cutting-edge innovation project

F

unded by Ofgem’s Network Innovation Allowance, the HV Pilot project will use smart meter data, helicopter survey insights, and machine learning to map how high voltage (HV) networks connect to low voltage (LV) systems This data-driven approach will help identify where reinforcement might be needed to accommodate growing demands for electricity, particularly in rural areas where single-phase HV sections and transformers can lead to network imbalances and inefficiencies.

David Penfold, innovation and deployment engineer at National Grid Electricity Distribution, said: “Understanding exactly how our HV network is connected at a phase level is essential for a smarter, more flexible grid.

“This project empowers us to make data-driven decisions, leading to optimised rural infrastructure. It’s

about precision, innovation, and preparing for a future powered by clean, reliable electricity.”

Gav Berry, secondary modelling engineer in the National Grid DSO modelling and analysis team, said: “Accurate phasing data can improve National Grid Electricity Distribution power system models, and provide network designers with the information required to design a balanced and efficient electricity network.

“We’re looking forward to working with CGI and Loughborough University to see how we could make this innovative method work.”

The HV Pilot, with partners CGI and Loughborough University, aims to deliver a low-cost, scalable solution to improve phase balancing without the need for additional visual surveys. If successful, the project could save up to £2.9 million through targeted interventions and improved network management. It could also reduce voltage issues for rural customers, improve efficiency and increase the number of connections opportunities.

FOUR STEPS TO MINIMIZING DOWNTIME WITH SMARTER ELECTRICAL ASSET MANAGEMENT

U

nplanned downtime can be extremely costly to businesses.

According to a 2023 survey

by ABB of plant maintenance decision-makers, unplanned downtime costs plants an average of EUR 147,000 per hour1, which equates to over one million Euros per day. Additionally, a staggering 69 percent of industrial businesses globally experience unplanned outages at least once a month. But the total cost of downtime is more than simply being off-line for an hour – there are also knock-on effects to consider. For example, in the food and drink industry, a day’s revenue might be lost as lines need to be reset and sterilised before production can resume. Or if a blast furnace goes offline it could be multiple days before production is back up and running. Downtime may also have a resulting impact on customer satisfaction and brand reputation.

To reduce the risk of unplanned downtime, there are four steps plant engineers can take:

1. TAKE A PROACTIVE APPROACH As electrical distribution and management systems increase in size and complexity, there are more components and subsystems and more points of potential failure. So, reactive maintenance becomes increasingly difficult.

First on the list should be to implement predictive asset management as this can decrease maintenance time and downtime by 30 percent, helping customers achieve a 40 percent OpEx cost reduction compared to a time-based maintenance strategy. Proactive maintenance strategies focus on preventing equipment issues before they arise and can be achieve by regular inspections and scheduled maintenance, and predictive analytics to ensure optimal asset performance.

2. I MPLEMENT AI AND PREDICTIVE ANALYTICS Digitalization is enabling plants to take a more proactive approach to 1 https://new.abb.com/news/detail/107660/ abb-survey-reveals-unplanned-downtime-costs125000-per-hour

Massimo Muzzì, Head of Strategy, Business Development and Sustainability, at ABB Electrification maximizing efficiency and performance of digital assets. For example, implementing Artificial Intelligence and Machine Learning can help plant and maintenance managers to analyse and interpret data to recognise when a device is expected to fail, before it actually does.

Legacy systems and older equipment can be retrofitted to provide predictive functionality. For example, non-digital circuit breakers can be upgraded with more intelligent, digitally-enabled breakers which are linked to monitoring systems.

This is more cost effective than replacing an entire installed base of assets, and can help facilities improve their energy capacity by up to 20 per cent, at the same time as reducing operational costs by up to 30 per cent.

This approach is one that has been implemented by both ENGIE, one of Europe’s leading energy suppliers, who was seeking to safeguard and extend the life of its switchgear systems, as well as Kemijoki Oy, one of the most important players in Finland’s renowned carbon neutral electricity system.

3. MODERNIZE ELECTRICAL ASSETS Another way that costly risks of downtime can be mitigated is by modernising and upgrading the existing electrical assets. There are additional benefits to this approach too, as upgrading systems not only extends the working life of equipment, but can also lower operating costs and improve sustainability.

One example of this approach, is when one of Sweden’s largest cogeneration plants, Mälarenergi, worked with ABB to modernise its 16 switchgear units. Aging circuit breakers were replaced with modern Emax2 models – featuring Ekip Hi-Touch relay protection and energy metering.

Not only were the electrical circuits fully protected, but new technology features help to reduce energy consumption, cost and resources. As a result of the upgrades,

ENERGY MANAGER MAGAZINE • JUNE 2025

critical infrastructure had its lifespan extended, removing the carbon consumption associated with manufacturing an entire new system, as well as additional transportation costs and inevitable emissions.

4. C ONSIDER THE POWER SUPPLY TO ENHANCE SECURITY As facilities place greater reliance of their electrical infrastructure for business continuity, its uptime is becoming more important. Another way to ensure a consistent supply power to is consider where the energy is coming from. Rather than rely on importing fossil-fuel-based power sources (which are subject to volatile cost fluctuations and political interference) some plants are installing renewable energy sources such as wind turbines and solar panels on site. This enables them to generate their own clean energy and control the supply.

Locally-generated power sources can be incorporated into Battery Energy Storage Systems (BESS) and microgrids.

These systems eliminate businesses’ traditional reliance on utility companies to satisfy their energy needs. It also reduces an organization’s dependence on traditional diesel- or gas-powered backup generators, further reducing carbon emissions and the commercial impact of volatile fossil fuel costs.

In a bid to improve uptime there are many factors to consider, but putting in place effective proactive asset maintenance and management strategies can go a long way towards helping organisations avoid costly downtime. Furthermore, embracing digitalisation, modernising equipment and considering the energy supply can help to improve the efficiency of equipment, reduce energy bills, and improve operational resilience.

NATURAL GAS AND SOFC: A VERSATILE AND SCALABLE SOLUTION FOR DISTRIBUTED POWER

G

lobally, electricity grids are facing increased strain due to the combination of rising demand, aging infrastructure and the need to integrate renewable energy sources.

When a new opportunity needs a reliable, constant, power source, developers are facing issues with either slow grid connections (up to 10 years in the UK) or long project delays associated with traditional solutions (7-8 years).

Data centres, which are dependent on large-scale GPU arrays, consume a lot of energy. According to the UK National Grid Electricity System Operator, data centre electricity consumption is set to increase to just under 6% of the UK’s total consumption by 2030. However, data centres are essential to countries who want to remain competitive in the age of data and AI. The challenge extends beyond powering the AI infrastructure; it involves the need of doing it quickly and in an environmentally friendly manner.

The urgency of connecting these data centres to an energy source, preferably a clean and sustainable one, is also at odds with the slow ‘time to power’ associated with traditional, electric grid connections.

AI data centres require swift, flexible energy solutions that can keep pace with their rapid development timelines.

Solid Oxide Fuel Cell (SOFC) systems are a clear solution to this urgent need.

They are both capable of running efficiently on natural gas and can be manufactured at scale in dedicated factories and delivered onsite in a faction of the time compared to other options. They are also modular, so have redundancy built-in, and generate power directly where it’s used and so don’t incur any electricity transmission losses.

Whilst one of the chief advantages of SOFCs is their fuel flexibility, being able to operate on a variety of fuels, including biogas, ammonia, and hydrogen, they were originally developed to operate efficiently on natural gas.

We believe that by providing solutions that can use existing fuels such as natural gas today, whilst providing fuel optionality for future, presents a very strong use case for the industry.

10

Nick Lawrence, Chief Product Officer of Ceres Natural gas is not only widely available and is supported by extensive transmission networks, but also offers a cost-effective way to rapidly meet the energy demands of AI data centres.

A NATURAL PARTNER Natural gas is an ideal partner for SOFC, with benefits on many levels.

With extensive national transmission networks already in place, natural gas can be quickly and efficiently distributed to where it is needed most.

Importantly, the design of SOFCs allows for easier and lower-cost carbon capture, making them a more attractive alternative to gas turbines, even when powered with by natural gas.

The global supply of natural gas is abundant. Securing a reliable energy source for the long term and its transmission ensures significantly less energy loss during transport compared to electricity, which experiences substantial losses due to its conversion process.

While its cost-effectiveness enhances its appeal, particularly for energy-intensive operations such as AI data centres.

Advancements in Ceres’ SOFC technology are driving down production costs, increasing scale and reducing environmental impacts. As manufacturing processes improve and economies of scale are achieved, the cost of producing SOFC units decreases. This is then met with the relative low cost of natural gas supply.

The affordability of natural gas as a source of energy is even more advantageous for systems and processes that, like data centres, require a constant, uninterrupted power supply to maintain 24/7 operations. The continuous and reliable power output of SOFCs meets the non-stop demands of global digital infrastructure, ensuring that data centres can function effectively around the clock.

This is why tech giants like Google or Microsoft have been exploring the

ENERGY MANAGER MAGAZINE • JUNE 2025

use of SOFCs to power their facilities, increasing energy efficiency and decreasing reliance on grid electricity through research and pilot programs. In the case of Microsoft, the company has been exploring fuel cell technology since 2013 and, in 2020, it made part of their commitment to become carbon negative by 2030.

Equinix, which owns and operates over 260 International Business Exchange data centres worldwide, has also deployed alternative energy sources, including SOFCs, in some of its 73 locations across the globe.

In Europe, the company has fully incorporated fuel cell technologies to reduce its carbon footprint.

While SOFC technology is still in early adoption stages, these examples show that large tech companies are actively exploring its potential to create cleaner, more reliable energy solutions for their data centres. This movement aligns with the industry’s increasing focus on reducing energy consumption and increasing the use of renewable energy.

A CLEANER FUTURE SOFCs produce significantly fewer greenhouse gas emissions when compared to traditional power methods to further reduce the carbon footprint of the energy generation process.

Ceres is at the forefront of this technological evolution, working to enhance efficiency and reduce the costs of SOFC technology. Through strategic partnerships, and a commitment to research and development, Ceres is set to introduce advanced SOFC solutions that promise to be transformative for powering AI data centres. These developments will provide a cost-effective and environmentally responsible way to meet the burgeoning energy needs of the digital age. www.ceres.tech

OPINION

RENEWABLE STANCE OF MAJOR OIL AND GAS COMPANIES REFLECTS CUSTOMER & SHAREHOLDER ATTITUDE Chris Goggin reviews the recent decision to reverse renewable investments in favour of increasing fossil fuel opportunities. BP is the latest global energy company to reduce investments in clean power projects and what this means for the direction of international and UK NetZero objectives.

B

P has formally announced a strategy reset of their targets set five years ago by the previous chief executive who has since left the company. During 2020 BP announced a new strategy that would aim to reduce oil and gas production at 40% by the end of the decade.

Investments would instead target the emerging low carbon energy market. BP promised to limit fossil fuel production to around 1.5 million barrels a day by the end of the decade. For perspective, in 2018 BP produced 3.7 million barrels a day.

Since then, BP has recently scaled back these objectives and redefined their approach – BP will now reduce production by 25%, meaning that BP will still produce around 2 million barrels a day by 2030. BP will now direct $10 billion a year of investment towards oil and gas projects whilst reducing $5 billion a year from their green energy strategy.

Current CEO Murray Auchincloss is quoted as saying: “Our optimism for a fast [energy] transition was misplaced, and we went too far, too fast.”

BP will now refocus on starting 10 large-scale fossil fuel projects by 2027 with a possible 8 to 10 more by the end

12

of the decade – 2030. Amongst the projects supposed to be cancelled is the £100 million HyGreen Teesside green hydrogen project. This facility was supposed to contribute 5% of the UK’s aim of introducing 10GW of hydrogen capacity into the UK grid by 2030.

BP has lost commercial ground to their rivals Shell and ExxonMobil in the last 2 years and has effectively lost a quarter of its market value.

Shell and ExxonMobil have seen their market value increase over the last 2 years, as both companies have been concentrating on oil and gas production.

To replace lost revenue BP is planning to sell $20 billion of assets including the noteworthy BP subsidiary and solar power developer – BP Lightsource. BP also plan on potentially selling an additional subsidiary, lubricant company Castrol as well as their network of service stations in an attempt to cut $5 billion of costs by 2027.

Additional influences that BP are subject to include the 5% (£3.85 billion) stake share that activist hedge fund Elliot Management has acquired. An activist hedge fund is an organization that invests in a company and exerts pressure to force managerial and strategic change. Elliot Management

ENERGY MANAGER MAGAZINE • JUNE 2025

is widely expected to demand changes to increase market value.

BP’s competitors Shell and ExxonMobil in contrast have pursued opportunities that focus on fossil fuels rather than renewable alternatives.

Shell announced last year that they will reduce carbon-based climate targets.

Shell’s previous aim was to weaken carbon emission intensity of all sold energy by 20% at the end of the decade.

The new objective is to reduce carbon emission intensity by between 15-20%.

Carbon intensity refers to the carbon produced through each unit of activity as opposed to released atmospheric emissions. Shell’s new target allows the organization to produce more gas at lower emission intensity but will raise overall emissions as production increases.

Shell has also failed to set out “Scope 3” emission targets associated with their gas production and distribution. Scope 3 emissions consider the entire range of emissions created through an organizations value chain including elements that exist outside of direct company control like, suppliers, customers and product disposal. Shell’s gas business is expected to grow 50% by 2040.

OPINION

In 2021 Shell announced they will reduce oil output every year for the entire decade from the 2019 peak of 1.9 million barrels a day. Having completed a 2021 $9.5 billion sale from a stake in a Texas Permian basin project Shell announced that this had reduced its daily oil production to 1.5 million barrels a day.

Shell now plans to begin enough fossil fuel projects to add 500,000 barrels a day by 2025 highlighting a shift in strategy.

Shell has also stopped investing in offshore wind opportunities and instead focused on expanding their current portfolio of oil and gas projects.

ExxonMobil have not actively embraced renewable or alternative energies in the same way. The American organization instead aims to reduce carbon emissions by introducing a variety of low carbon energy sources into their product inventory.

ExxonMobil will invest around $20 billion to add fuels such as hydrogen, carbon capture and biofuels between 2022-2027.

Currently, ExxonMobil is the stronger company when compared to both Shell and BP. In 2024 Shell reported a net income of $5.4 billion in the third quarter of the year, down from $6.3 billion the previous year. BP reported a 30% reduction in net income at the same time, at $2.3 billion. Exxon Mobil announced net income in the third quarter at $8.6 billion – a 5.1% reduction from the previous year.

Gross yearly profits for ExxonMobil rested on $84.234 billion, Shell $23.72 billion whilst BP’s yearly gross profit is not as well advertised but published a net income of $8.9 billion down from $13.8 billion the previous year.

A subjective interpretation of current oil and gas companies moving focus away from ‘clean’ energy aims is that market and consumer demand for fossil fuels remains strong across all continents.

NetZero aims are not as highly valued by both the consumer and shareholder

when compared to lower energy costs and share prices.

However, an objective view could also claim that large energy companies will return to clean power objectives once the global market is in a better condition to be able to return profits from renewable investments.

UNLOCKING THE POWER OF PSYCHOLOGICAL THEORY TO TRANSFORM BUSINESS ENERGY RELATIONSHIPS Greg Kavanagh, Sales Director, Shell Energy UK

S

parked by geopolitical uncertainty and challenges around demand, the 2022 energy crisis thrust energy security and stable power supply into the spotlight for businesses across Europe. This is particularly true in the UK, where our dependence on gas and power generation led to increasing energy costs, supply chain disruptions, and heightened concerns over longterm affordability for businesses.1 More recently, as price volatility and reliability concerns returned, many companies switched suppliers with some prioritising short-term cost reductions over long-term stability. A recordbreaking 113,000 businesses changed energy providers in October 20242.

But is this transactional mindset holding some businesses back?

I believe that focusing on price and viewing energy as just another cost on the balance sheet underestimates its true potential as a strategic asset that can drive growth, resilience and competitive advantage.

So, how can businesses shift to a smarter, more strategic approach that enables them to derive greater value from their energy contracts?

One approach is to harness a classic psychological theory: Maslow’s Hierarchy of Needs3, and his concept of ‘laddering up the hierarchy’ to match one’s evolving needs.

needs and motivations through an ascending five-stage model, beginning with our survival essentials such as food and water.

The core principle is simple: humans need to meet their essential survival needs before they can consider growth needs. The same principle applies to businesses: just as humans need reliable sources of food and water, organisations need reliable energy provision.

When businesses have complete confidence in their energy provider’s ability to withstand market volatility, they are more willing and able to invest in long-term growth. In an unusually volatile environment of geopolitical tension, fluctuating prices and regulatory changes – this requires an energy supplier that is financially robust. Ideally, they should have several decades’ experience navigating international energy markets, advanced trading capabilities, extensive business and government relationships, and broader stakeholder networks.

This is why I think getting the basics right is critical. If I were looking after procurement, I would want certainty that the partner I choose could provide the level of service they have committed to throughout the duration of the contract – no matter what else is happening in the world.

STEP ONE: BUILD ON THE STRONGEST FOUNDATIONS

STEP TWO: DIVERSITY OF SUPPLY EQUALS SECURITY

Maslow’s Hierarchy of Needs is a psychological theory exploring human

Maslow’s second tier – safety and security – is equally fundamental for creating an optimal energy strategy.

During times of volatility, it is more important than ever that energy supply is both predictable and adaptable to changing market conditions, so businesses can survive, find stability and therefore focus on growth.

The 2022 energy crisis highlighted

ENERGY MANAGER MAGAZINE • JUNE 2025

how relying on a single energy supply source creates vulnerability. Businesses that seek out providers with access to a diverse energy portfolio have been more successful in shoring up future energy security and mitigating market volatility.

A diversified portfolio can include alternative power sources such as liquefied natural gas and biomethane in addition to conventional gas and power.

This helps to spread the risk, enabling businesses to reduce dependence on any single energy source, therefore helping to manage energy price and security while staying resilient against market and regulatory changes.

Renewable energy sources such as wind, solar and hydro can also be used for similar purposes. As the United Nations notes: “Reliable renewable energy technologies can create a system less prone to market shocks and improve resilience and energy security by diversifying power supply options.”4 While choosing a provider based on price alone is an understandable choice for businesses, it inevitably reduces the customer-supplier relationship to a commodity exchange and nothing more.

Selecting a trustworthy energy provider that can provide security, handle market fluctuations, and in some cases, unlock untapped revenue streams for businesses, elevates that relationship to a strategic one. In turn, this relieves businesses from having to constantly monitor and navigate market volatility, 4 https://www.un.org/en/climatechange/raisingambition/renewable-energy

OPINION

giving them a chance to focus on the bigger picture and foster growth.

STEP THREE: BUILDING STRONGER ENERGY RELATIONSHIPS The next tier of Maslow’s theory, ‘love and belonging’, may seem somewhat removed from energy contracts.

However, as businesses evolve and their needs become more complex, building meaningful relationships with their energy provider becomes key to unlocking value. It is also a growing trend.

According to a ecent article in Procurement Magazine, while price and cost savings remain a primary objective, procurement’s role has grown to focus on broader value creation. The publication adds that “procurement leaders are now looking beyond immediate cost reductions to consider long-term value including sustainability benefits, innovation opportunities and strategic partnerships.”5 Meaningful progress can happen when businesses prioritise long-term relationships with their energy providers, viewing them as collaborators rather than mere commodity suppliers. This is a view shared by Hydro, which sees long-term partnerships as key to its decarbonisation journey. “As we work towards net-zero, selecting the right energy partner is a board-level priority. We needed a provider that understood our industry, our ambitions, and could support us in the long run,” says Lars Lysbakken, Energy Portfolio Manager at Hydro.

Though decarbonisation is often discussed in the procurement process, it can be overlooked in favour of dayto-day pressures. Organisations can maintain progress on their ambitions to reduce emissions while meeting near-term business needs through working with an energy provider that offers tailored decarbonisation strategies and options that can be scaled up – such as renewable natural gas, energy management strategies, energy efficiency consultancy, or environmental products.

This type of relationship enables 5 https://procurementmag.com/top10/top-10procurement-trends-2024

businesses to get maximum long-term value while meeting their energy goals securely, reliably and in a cost-effective manner.

STEP FOUR: TAILORING YOUR ENERGY STRATEGY The fourth stage of Maslow’s theory – confidence, achievement, and individuality – might be the most relevant and exciting, as impactful energy providers recognise and adapt to businesses’ unique needs.

While short-term fixed contracts can provide stability, they can also limit flexibility and hinder the longer-term strategies needed for transformational growth. The right energy provider can tailor solutions to match specific operational and strategic goals, or even risk appetite. Flexible purchasing products and power purchase agreements (PPAs), combined with a mix of conventional and renewable options can all help to meet changing needs.

Bespoke relationships empower businesses to evolve from passive energy consumers to active players in the energy landscape. Flexible procurement plans provide them with the confidence that they can adapt swiftly to market changes and adopt a more agile and resilient energy strategy that puts businesses in control.

STEP FIVE: UNLOCKING PEAK POTENTIAL At the pinnacle of Maslow’s hierarchy theory lies self-actualisation, which he describes as the freedom to realise true business purpose and direction.

Transposed to the energy world, this would enable a procurement relationship to go beyond delivering power and gas, and empowering businesses to thrive.

As the world transitions to net-zero emissions, energy systems are becoming increasingly decentralised, with more renewable, local electricity entering the grid. Battery systems can help to balance supply and demand, giving businesses

the power to become more self-sufficient and take charge of their energy needs.

Virtual power plants (VPPs) are also revolutionising how businesses manage energy, integrating distributed resources such as solar, battery storage, and flexible demand into a single intelligent network.

By optimising energy use and market participation, VPPs like EGO6 – recently acquired by Shell in Italy – contribute to a more flexible, sustainable and resilient energy system that can empower industrial and commercial customers to take control of their energy strategy, security and decarbonisation pathways.

At this level, the relationship with the energy supplier is focused on enabling customers’ innovation, resilience, and industry leadership.

HOW PSYCHOLOGICAL THEORY POWERS POSSIBILITY In an increasingly uncertain world, energy can be seen as a dynamic force for positive change through strategic relationships that can fuel innovation and drive competitive advantage.

Maslow’s Hierarchy of Needs illustrates how the most enriching outcomes come from responding to higher aspirations. The same can be applied to the energy sector. At a foundational level, reliability and security are essential. However, real and sustained value emerges when businesses prioritise partnerships that elevate their ambitions, rather than merely meeting their basic requirements.

Energy has the potential to be more than just an additional cost on balance sheets, it can be a catalyst for progress. By working with trusted energy allies, businesses can evolve from keeping the lights on to achieving their boldest vision for the future. https://uk.shellenergy.com/ 6 https://www.shell.com/shellenergy/shellenergy-europe/news-and-insights/fromsunshine-to-software-shell-acquires-virtualpower-plant-in-italy.html

OPINION

POWER PRESCRIPTION: WHY OPEN PROTOCOL PLATFORMS PAVE THE WAY TO RESILIENT HEALTHCARE

H

ealthcare facilities in the UK and across the globe are under severe pressure.

Ageing infrastructure, extreme weather events caused by climate change, and cyberattacks leading to power blackouts are threatening their ability to provide continuous, quality healthcare. In addition to these risks, the transition to greener energy makes electricity supplies more unpredictable, even as hospitals require more power to run advanced medical technologies.

To overcome these hurdles, hospitals must operate in a more agile and efficient manner without compromising patient care. Connecting equipment, devices, and technologies from various providers through an open protocol platform is essential for building the resilience needed to address these challenges confidently.

With modern hospitals consuming up to 2.5 times more energy per square foot than typical commercial buildings, they are often hampered by power supply challenges.

Nigel Thomas, ABB’s National Specification and Projects Sales Manager, takes a closer look at this urgent yet underreported crisis and offers modern solutions to safeguard uninterrupted electrical power.

THE PRIMARY CHALLENGES Hospitals are like small cities in their energy demands. With a multitude of equipment – ranging from life-saving devices to basic operational tools – these demands are immense. Heating, ventilation, and air conditioning (HVAC) systems alone account for around half of all energy usage in hospitals. To deliver reliable patient care, they must have a stable, uninterrupted electricity supply.

However, as healthcare becomes increasingly digital, hospitals’ carbon footprints have grown to concerning levels. So much so that, if global healthcare were a country, it would be the fifth-largest greenhouse gas emitter on Earth. Therefore, hospitals face the challenge of embracing innovative yet energy-intensive technologies while also maintaining sustainability. They must also strike a delicate balance between improving conditions for patients and staff while becoming more energy-efficient to reduce emissions.

Stakeholders, primarily patients and healthcare providers, bear the brunt of energy reliability issues. Patients,

16

for instance, depend on stable energy to power life-support machines; any interruption, even for a minute, can be detrimental to their well-being.

The economic ramifications are also alarming. A hospital power outage can cost upwards of $7,900 per minute, reflecting not only financial loss but also potential degradation of patient trust and hospital reputation.

Cybersecurity is another concern.

As hospitals implement digital systems, the risk of cyberattacks, particularly

ENERGY MANAGER MAGAZINE • JUNE 2025

ransomware, increases. These attacks can have severe implications if energy management systems are compromised. Thus, deploying secure energy management software becomes imperative. By utilising encrypted communication and constant monitoring, these systems can effectively ward off potential threats.

Hospitals must continually innovate to meet evolving patient needs. Yet, building or redeveloping hospitals has grown significantly more costly, mainly

OPINION due to shortages of specialist skills and increasing labour expenses. This situation presents a challenging task for healthcare providers, who must carefully balance competing priorities: keeping pace with technological advances while managing and controlling escalating costs.

OPEN PROTOCOL PLATFORMS AND OTHER SOLUTIONS To tackle these challenges, hospitals must embrace innovative and sustainable energy solutions. A promising approach lies in the adoption of open protocol solutions, which facilitate interoperability among various pieces of equipment.

These systems enable hospitals to select the best-suited technology, minimising the risk associated with vendor lockin, which can hinder upgrades and adaptability. Open protocols also improve seamless data transfer, enabling more informed decision-making – crucial for efficient energy management and robust power monitoring.

Energy management systems must evolve to integrate smart technologies seamlessly, such as an intelligent power network, which acts as the hospital’s central nervous system. This interconnected approach enables facilities to anticipate and address issues promptly, thereby reducing the risk of power outages. Hospitals must also maintain strong connectivity across their electrical systems while integrating new

technologies, such as human-centric lighting, in-room sensors, and voice control activation, all while simultaneously reducing energy consumption.

Another critical solution is the integration of Uninterruptible Power Supply (UPS) systems. High-efficiency UPS units ensure long-term system availability, significantly reducing carbon emissions while safeguarding against sudden power outages.

WHY HEALTHCARE PROVIDERS NEED A CONNECTIVITY PARTNER Working with a connectivity partner in the initial stages of development allows hospitals to build a digital

ecosystem that optimises for today and lays the groundwork for the future.

Having access to cutting-edge, flexible, and scalable systems is crucial for building the infrastructure necessary to maintain mission-critical uptime.

The path to better energy reliability in hospitals hinges on embracing open, secure, and flexible solutions that are future-proofed against both technological and environmental changes. By addressing inefficiencies and adopting comprehensive energy strategies, hospitals can boost their service delivery, meeting immediate and future healthcare demands with confidence. https://global.abb/

NET ZERO

NET ZERO EXPLAINED, DISPELLING MYTHS FOR A GREEN FUTURE

In recent years, the term “net zero” has become a buzzword in discussions about climate change and sustainability.

However, there are several myths and misconceptions surrounding this concept. TEAM Energy has asked some of its Energy Consultants to debunk the most common myths and shed light on the reality of achieving net zero.

Myth 1: Net zero means zero emissions. Timothy Holman, Head of Consultancy One of the biggest misconceptions is that net zero means eliminating all emissions. In the UK, net zero has a clear legal definition under the Climate Change Act 2008 (2050 Target Amendment) Order 2019. It means cutting greenhouse gas emissions by at least 100% compared to 1990 levels by 2050.

In reality, net zero refers to balancing the amount of greenhouse gases emitted with the amount removed from the atmosphere. This involves drastically reducing emissions at the source and addressing only residual emissions, those that are unavoidable, with offsetting measures. Residual emissions are expected to account for no more than 10% of total emissions.

Working towards net zero is all about creating a balance while striving for a more sustainable future.

Myth 2: Net zero is only about carbon. Sophie Legg, Data Analyst While carbon dioxide is the primary greenhouse gas contributing to global warming, net zero encompasses a range of greenhouse gases, including methane (CH4), nitrous oxide (N2O), and fluorinated gases, such as hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs). These

18

gases vary in their sources and warming potential but collectively impact climate stability. Achieving net zero requires addressing emissions from sectors such as agriculture – where methane emissions stem from livestock; industry – producing nitrous oxide and fluorinated gases through manufacturing processes; transportation – primarily emitting carbon dioxide from fossil fuel combustion; and energy production from fossil fuels (coal, oil, and natural gas). Effective strategies to mitigate these emissions involve reducing reliance on fossil fuels, enhancing efficiency in industrial and agricultural practices, transitioning to renewable energy sources, and investing in carbon capture technologies to offset any residual emissions.

All sectors play a significant role in the UK’s greenhouse gas emissions profile, and targeted strategies are essential to mitigate their impact.

Myth 3: Net zero is too expensive. Sam Arje, Senior Energy Consultant Many believe that achieving net zero is prohibitively expensive. However, the costs of inaction – rising global temperatures, extreme weather events, and disrupted supply chains – are far greater. Investing in sustainable practices and technologies is not only essential for addressing these risks but can also result in long-term savings and

ENERGY MANAGER MAGAZINE • JUNE 2025

economic opportunities. For businesses, aligning with climate mitigation plans such as adopting renewable energy, improving efficiency, and integrating low-carbon technologies can enhance resilience and competitiveness.

Additionally, there are incentives, grants, and funding available to support the transition to net zero.

Organisations are further encouraged to be guided by frameworks like the Task Force on Climate-related Financial Disclosures (TCFD), which requires organisations to report on their climate-related risks and strategies.

By aligning with TCFD requirements, organisations can demonstrate accountability, attract investment, and better position themselves for future regulatory changes. Proactively transitioning to net zero is not just a moral imperative – it is a smart and forward-thinking business strategy.

NET ZERO

Myth 4: Net zero is only for big corporations. Tom McLeish, Energy Consultant Net zero is not an ambition reserved for large corporations; smaller businesses play a crucial role in contributing to this global goal. Simple actions, such as embracing energy efficient measures, and prioritising sustainable goods and services, collectively drive meaningful change.

These efforts also create ripple effects throughout the supply chain – which can account for up to 90% of an organisation’s total carbon emissions.

Therefore, suppliers and smaller businesses can play a vital role in a large corporations’ carbon reduction and the success of its net zero goals.

By implementing carbon reduction plans, small businesses prove their commitment and secure their future within the supply chain. Achieving net

zero requires collective commitment from all sectors, where even seemingly small contributions add up to create substantial environmental impact.

Myth 5: Net zero is a distant goal. Georgina Wisby, Energy Consultant Some people think that net zero is a goal for the distant future. As of 2024, 147 out of 198 countries worldwide have established some form of net zero target. The UK’s target is to achieve net zero by 2050 or even earlier, in some cases 2030. Depending on where you are as an organisation, 25 years is not as far away as you think. Reducing carbon emissions is undoubtedly a complex and challenging undertaking that will reveal bumps in the road, but it is an essential step in addressing the climate crisis. Gaining a clear understanding of the different types of emissions, harnessing near real-time data, engaging

stakeholders, and fostering collaboration across the supply chain, can take time.

But organisations can take meaningful strides toward their sustainability goals once the first steps are made. By adopting sustainable practices now and utilising effective tools to drive change, we can collectively accelerate the journey toward achieving net zero and create a more resilient, sustainable future.

FINAL THOUGHTS Achieving net zero is a complex but necessary goal to combat climate change. By understanding and debunking these myths, we can better appreciate the efforts required and the benefits of reaching net zero.

It is a collective responsibility that involves governments, businesses, and individuals working together to create a sustainable future. www.teamenergy.com

ENERGY STORAGE

PUBLIC SECTOR DECARBONISATION: THE ROLE OF ENERGY STORAGE

T

he UK has committed to reach net zero by 2050, while the public sector has set an important interim milestone of reducing emissions by 75% by 2037 compared to a 2017 baseline. These ambitious targets are driving action across the public estate to improve the energy efficiency of public buildings.

The primary way to achieve this is often to improve the building fabric and implement controls and behavioural strategies to reduce the energy demand of buildings and to install a low carbon heating system, typically a heat pump.

Whilst these interventions will result in reduced direct carbon emissions, depending on the design and operation of the system the building users can be confronted with uncertainty around optimisation and the possibility of higher annual energy bills. To protect the public purse and ensure the revenue available goes towards delivering vital public services, as opposed to soaring electricity bills, energy storage can be explored as a buffer to these high costs through shifting energy demand away from peaks.

The Heat and Building Strategy (2021) highlighted the need for energy storage to produce a flexible energy system, one that is cost-effective, efficient and secure. The expected role of energy storage is there; through thermal stores (storing hot water in tanks or in district heating systems) and/or battery storage (storing energy as electricity), though the potential feels yet to be fully realised in the UK. The Climate Change Committee’s Seventh Carbon Budget suggests the need to deploy 35 GW of short-duration batteries by 2050, more than a ten-fold increase on 2023 levels, demonstrating we still have a way to go in terms of achieving the flexible energy system we need to decarbonise at scale and pace.

Energy storage will be an important tool in operationalising the decarbonisation of heat across the public sector. Thermal stores have multiple economic, technical and environmental benefits for heat pump systems and district heating as identified in CIBSE AM17 (2022) and CIBSE CP1 (2020); they can provide system stability, resilience

20

Becca Weight, Salix Energy and Carbon Programme Manager and crucially for the public sector, peak-lopping. Peak-lopping means that large storage volumes can be used to meet the demand at peak times, allowing the potential for both reducing the size of electrical grid connection and reducing peak demand charges to optimise energy spending. With public sector organisations often experiencing delays and unexpectedly high costs when requesting an upgrade through their Distribution Network Operator (DNO) as part of a decarbonisation project, the benefits of thermal stores should definitely be considered.

Furthermore, it is expected that the Heat Network Technical Assurance Scheme (HNTAS) will build on the standards set out in CP1. Heat networks currently provide 2-3% of the UK’s heat demand but are expected to provide 20% by 2050 to reach net zero. With the expected future implementation of low carbon heating plant in energy centres, thermal stores will provide future flexibility for heat networks therefore improving the consumer experience.

Based on this direction of travel those designing new, or extending existing, heat networks would do well to consider the role of thermal stores as early on as possible to avoid unexpected costs or delays in achieving HNTAS certification.

Battery storage will play a similar role in enabling the public sector to decarbonise their building stock. When combined with renewable energy installed onsite, for example rooftop solar, the energy created can either be used or stored for later use. The ability to use energy generated onsite reduces reliance on the grid, saving the building user valuable money.

Depending on demand, batteries can also be used to store electricity imported from the grid at cheaper times of the day which can either be used during peak periods or sold back to the grid.

As with any energy project, an objects appraisal should be conducted to explore the benefits and limitations of

ENERGY MANAGER MAGAZINE • JUNE 2025

energy storage, which will be bespoke to each building. Design, spatial and planning requirements must be considered early on in the design process to give confidence in the feasibility of installation.

At Salix we deliver the Public Sector Decarbonisation Scheme on behalf of the Department for Energy Security and Net Zero. Public sector organisations are eligible to apply for grant funding for heat decarbonisation and energy efficiency projects, with new schemes historically running annually. Applicants are encouraged to take a whole building approach to decarbonisation to ensure that low carbon heating systems are designed appropriately, that the thermal comfort of building occupants is maintained and that projects present good value for public money. To achieve this approach applicants are eligible to apply for thermal stores and battery storage in conjunction with the installation of a low carbon heating measure in each building proposed.

Whilst there are some restrictions around utilising grant funding for commercial gain (e.g., applicants are typically not permitted to export electricity to the grid), the inclusion of these measures in the eligible technologies list demonstrates technical justification and political drive for the implementation of these technologies as part of a bundle of decarbonisation measures.

If we are to reach net zero, with critical action required at a time of financial cuts across the public sector, it is crucial for public sector organisations to leverage their experience, passion and funding towards low carbon solutions that provide value over the long term.

Energy storage will be an important tool in achieving this, based on the financial savings available, and its role is only expected to grow as we continue our net zero pathway. www.salixfinance.co.uk

EMPOWERING ENERGY MANAGERS TO ACHIEVE NET ZERO WITH INTELLIGENT BATTERY STORAGE

T

he UK is moving full speed towards its 2050 net zero target, and solar energy is playing a major role in that journey. As of February 20251 over 1.73 million solar installations have been completed nationwide, contributing to a combined 18GW of clean energy. While domestic uptake continues to grow, commercial rooftop installations now account for around 20% of solar deployment - a clear sign that businesses and energy managers are getting serious about cutting carbon.

But putting solar panels on roofs is just the start. To get the most out of solar energy, we need to store it and use it smartly. That’s where intelligent battery storage such as Levelise comes in. To fully realise its benefits, solar needs to be paired with intelligent battery storage systems that not only store excess generation, but actively manage how and when energy is used, traded, or exported. By combining solar and smart storage, organisations can lower their energy bills, reduce their carbon footprint, and even earn extra income – all while helping the UK create a cleaner, more flexible energy system.

TURNING SOLAR INTO SMARTER SAVINGS These energy management solutions 1 https://www.solarpowerportal.co.uk/ukcrosses-18gw-solar-milestone/

Ivan Castro, Operations Director at Levelise help to unlock the full value of solar and battery systems. By aggregating thousands of batteries across the UK, it creates a powerful virtual power plant capable of participating in grid flexibility services. It intelligently manages stored energy, allowing residents and businesses to benefit not only from time-of-use optimisation, but also from trading excess capacity into the energy markets and providing balancing services to the National Energy System Operator (NESO).

For energy and sustainability managers focused on delivering both financial and environmental performance, this creates an exciting opportunity. You’re no longer just cutting costs - you’re turning your building or property portfolio into an active part of the energy system, contributing to grid resilience and carbon reduction.

Whether managing residential schemes, commercial premises, or public sector buildings, participation in energy markets and demand-side response programmes can generate tangible income alongside the expected bill savings and carbon reductions.

FASTER PAYBACK AND GREATER IMPACT One of the biggest benefits of adding smart storage to a solar setup

is a shorter payback time. Rather than waiting many years to see a return, organisations can now start saving - and earning - within the first 12 months.

But the advantages aren’t just financial. These systems also help reduce reliance on fossil-fuel electricity from the grid, cutting carbon emissions and supporting your organisation’s sustainability goals. If your business is working towards environmental targets or needs to report on carbon performance for ESG or compliance reasons, the data from these systems makes it easier to track and report progress.

LONG-TERM ENERGY STRATEGY Beyond the immediate financial gains, these systems support stronger, longer-term customer relationships.

With ongoing system monitoring, monthly performance insights, and continued optimisation, end users remain engaged with their energy system long after the installation is complete.

As the energy system evolves, energy managers have a critical role to play in leading that change.

Intelligent battery storage is helping to make that role more strategic, more impactful, and more future-ready than ever. https://www.levelise.com/

BRIDGING THE RESILIENCE GAP: HOW BATTERY STORAGE IS SECURING BRITAIN’S ENERGY FUTURE

E

urope’s electricity grid is under unprecedented strain.

From the catastrophic Iberian Peninsula blackout that left 60 million people without power to substation fires that recently paralysed Heathrow Airport, the warning signs are mounting. As Britain races towards its 2035 target of 100% decarbonised electricity, a critical question emerges: how do we maintain grid stability whilst rapidly transitioning to renewable energy?

The answer lies in fundamentally reimagining how we manage and distribute electricity, with innovative battery energy storage systems proving transformational particularly when deployed at the grid edge where vulnerabilities are most acute.

THE PERFECT STORM OF GRID CHALLENGES Britain’s electricity infrastructure faces a perfect storm. Approximately 40% of Europe’s distribution grids are over 40 years old, with the average UK transformer exceeding 60 years of age. This ageing infrastructure was designed for oneway power flow from large, centralised generators, not the bidirectional flows required by distributed renewable sources.

Traditional power plants provide crucial grid stability through inertia – the kinetic energy of spinning turbines that maintains the 50Hz frequency fundamental to grid stability. As renewables lack this stabilising effect, Britain’s grid becomes increasingly vulnerable to frequency fluctuations that can trigger cascading failures.

Recent events underscore these vulnerabilities. The 2019 UK blackout affected one million homes when both the Little Barford gas plant and Hornsea wind farm failed within minutes. Storm Arwen left nearly one million homes without power, with some enduring week-long outages. The Heathrow substation fire cost the UK economy an estimated £80 million in a single day.

As an island nation with limited synchronous interconnectors to continental Europe, Britain must largely solve these stability challenges independently. With asynchronous generation now reaching 66% of total UK generation, innovative solutions are urgently needed.

22

BEYOND TRADITIONAL THINKING: DYNAMIC FLEXIBILITY The conventional approach – throwing more infrastructure at the problem – is neither economically viable nor technically sufficient. The European Commission estimates €2-2.3 trillion will be needed by 2050 to upgrade European power networks, with nearly 80% required for distribution networks.

Instead, we need “dynamic flexibility” - a three-dimensional approach beyond traditional battery storage thinking.

The first dimension addresses grid service flexibility; how batteries replicate and enhance traditional stability services. Modern battery systems provide ultra-fast frequency response within milliseconds, delivering synthetic inertia and precisely controlling reactive power to maintain voltage stability.

The second dimension focuses on deployment flexibility – where and when storage is utilised. Unlike traditional grid infrastructure requiring years to build, advanced battery systems deploy as “drop and go” solutions, operational within minutes and strategically relocatable where grid support is needed most.

The third dimension enables network flexibility – transforming grid architecture.

Rather than maintaining vulnerable centralised systems, battery storage enables interconnected microgrids capable of operating independently when necessary whilst working collaboratively during normal conditions.

THE GRID-EDGE REVOLUTION Allye Energy’s approach focuses on the grid edge - distribution networks where the greatest vulnerabilities exist – creating resilience close to communities and businesses where it matters most.

The recently launched MegaMAX range provides up to 1.5MWh of dispatchable energy with ultra-fast frequency response capabilities. These systems combine up to 18 repurposed EV battery packs with advanced AI-driven control systems, reducing embedded carbon by over 40% whilst providing industrial-grade reliability.

This approach creates a “network of networks” – interconnected microgrids

ENERGY MANAGER MAGAZINE • JUNE 2025

with inherent redundancy. When one area experiences failure, it doesn’t cascade across the entire system. Each microgrid can isolate itself, maintain critical services, and reconnect once stability is restored.

ECONOMIC AND ENVIRONMENTAL BENEFITS Grid-edge battery storage extends beyond reliability. These systems reduce energy costs by up to 50% whilst generating additional revenue through grid flexibility markets. Research suggests every pound spent on grid resilience today saves ten pounds in disaster recovery tomorrow.

Environmentally, the approach enables higher penetration of local renewable generation whilst reducing reliance on fossil fuel backup systems, accelerating the path to net zero whilst strengthening grid stability.

BUILDING TOMORROW’S GRID TODAY As Britain accelerates towards a renewable-powered future, the gap between clean energy ambitions and grid infrastructure capabilities will widen without decisive action. Countries embracing innovative grid flexibility approaches – particularly island nations like Britain – can transform vulnerability into leadership.

The technology exists today to bridge this resilience gap. What’s needed is collective commitment to reimagining energy infrastructure, supported by regulatory frameworks that properly value resilience and investment models recognising the multi-dimensional benefits of advanced battery storage.

Modern society depends on electricity flowing as reliably as oxygen. The time has come to ensure our grid infrastructure can breathe easily in a renewablepowered future. www.alleye.com

SMARTER WATER HEATING CONTROL YIELDS 30%+ SAVINGS

O

perators of multi-occupancy accommodation, such as student residences, hostels, and shared housing, face ongoing challenges in managing hot water systems effectively.

They face unique usage patterns, fluctuating occupancy levels, and a high demand for both comfort and operational efficiency. At the centre of these challenges lies the hot water cylinder: a seemingly simple piece of equipment that, when poorly managed, can lead to excessive energy consumption, inflated utility bills, system failures, and compliance risks.

Understanding the common issues with traditional hot water systems in these settings, and the benefits that tighter control and monitoring can offer, is key to future-proofing operations and improving sustainability.

LACK OF CONTROL AND VISIBILITY Most traditional hot water cylinders in multi-occupancy buildings use basic thermostatic controls or fixed-time schedules. Often heating water continuously, without real-time understanding of demand or occupancy.

This lack of visibility translates to guesswork. There is little or no data indicating when water is being used, consumption, or efficiently operating

cylinders. Without control, buildings often maintain hot water availability around the clock, even during periods of low or no occupancy, such as holiday breaks or weekends.This 'always-on' approach results in wasted energy and unnecessary wear on equipment.

AGEING COMPONENTS In many student accommodations, water heating systems include older immersion elements and poorly insulated cylinders. These degrade over time, becoming inefficient – consuming more energy to maintain the same output.

Old systems are also prone to temperature drift. The set temperature is not maintained accurately, leading to inconsistent hot water delivery, a common complaint among residents.

Additionally, older systems lack modern safety features like automated thermal disinfection, which helps prevent bacteria growth such as Legionella.

ENERGY AND WATER CONSUMPTION Heating water is one of the largest energy costs in multi-occupancy buildings. With outdated or uncontrolled systems, cylinders are heated far more frequently than necessary.

Water waste is another concern,

either through leaks, dripping taps or an intermittent faulty toilet cistern.

THE BENEFITS OF TIGHTER TEMPERATURE AND VOLUME CONTROL Implementing SmartTank as part of the Irus ecosystem offers a solution.

Cylinders that enable real-time temperature management and water measurement can transform hot water systems from a passive utility into a proactive asset.

Utilities efficiency – SmartTank enables much tighter control of heating, based on more accurate temperature measurement. Rather than heating all day, cylinders can be preheated before peak times and held at safe standby temperatures during low-demand periods.

SmartTank data reveals 31% energy saving, per bed over a year.

Leak detection is another feature. At one site SmartTank detected a year-long leak, wasting 14,000 litres of water per day!

PipeSense is a system addition, monitoring outlet temperatures, and detecting faulty toilet cisterns.

Maintenance and reliability – Monitoring temperature consistency and heating performance helps detect degrading elements before they fail.

Preventative maintenance can be scheduled more effectively, reducing downtime and emergency repairs.

Improved sustainability and reporting – Accurate water measurement gives operators clear insights to hot water consumption. Meaningful reporting from the Irus Portal enables targeted conservation efforts, helps meet sustainability targets, and supports transparent utility reporting.

Resident satisfaction – By ensuring reliable hot water supply and reducing downtime, residents’ comfort improves. Additionally, SmartTank prevents overheating or underheating, addressing common complaints around inconsistent temperatures.

The challenges posed by traditional hot water cylinders in multi-occupancy accommodation are real, but they are also solvable. With tighter temperature control and accurate water measurement, operators are dramatically improving utility efficiency, reducing waste, extending equipment life, and enhancing the living experience for residents. In an increasingly data-driven and sustainability-focused world, upgrading hot water systems is not just smart – it’s SmartTank. www.prefectcontrols.com

The Denbighshire Energy Team are continuing work to drive down energy usage and costs across its expansive and nuanced estate. The Team has managed projects across Council buildings, including schools and care homes to improve building energy efficiency and reduce emissions and usage costs over the longer term.

At the Council owned and operated Cysgod Y Gaer Residential Home for 30 occupants the fuel consumption for the hot water heating system has been slashed from 750kWh to just 200kWh per day – with the support of Rinnai products and design support services.

“This is a care home where we recently removed two hot water cylinders that were heated by the main heating boilers. We replaced them with high efficiency Rinnai water heaters that only heat water on demand. We can see the gas consumption has decreased from an average daily consumption of 750kWh down to 200kWh per day’ said a manager from the Denbighshire Energy Team.

RENEWABLE ENERGY

WHEN IS THE RIGHT TIME TO INVEST IN SOLAR?

Faced with rising energy prices, sustainability targets, and ageing infrastructure, many businesses are no longer asking if they should transition to solar power – but when.

Should investment happen now, or is it wiser to wait for better incentives, technological advancements, or infrastructure upgrades?

Ciaran Cotter, Head of Technical at Solivus, explores when to invest in solar and what key factors should guide that decision.

T

he future energy task is a complex one, especially for industry. On the one hand, there is the issue of maintaining business as usual and supporting new growth, while seeking to reduce operational costs and offset rising energy cost pressures.

At the same time, there is a pressing need to lessen environmental impact. As the UK’s net zero trajectory comes closer into sight, we continue to see new industry standards and carbon reduction expectations for businesses to get to grips with. Additionally, stakeholders – including customers, employees, and suppliers – are increasingly aligning themselves with businesses that demonstrate clear environmental responsibility.The result is increased onus on the environmental measures which can drive efficiencies and optimise energy consumption levels while helping to futureproof.

Against this backdrop, solar power presents a clear opportunity: it enables significant carbon reductions while minimising disruption and controlling energy costs. But despite its appeal, it can sometimes be difficult for businesses to ascertain when to make the switch.

A STRATEGIC RESPONSE TO RISING COSTS In our experience the most common catalyst for solar adoption is rising energy costs.

Businesses increasingly need to think tactically about grid usage and cost control. Whether triggered by increased energy demand, tariff changes, or grid constraints, strategic energy management has become a critical concern.

Take, for instance, an automaker that expands its operations with EV charging infrastructure. While a positive step toward electric mobility, it also introduces significant peak energy loads – driving up electricity bills and straining the grid.

In another scenario, a company might face new utility contract terms that include higher demand charges – fees tied to peak usage rather than total consumption.

These can inflate operating costs for energy-intensive operations.

In both cases, solar power – particularly when paired with battery storage – offers a way to self-generate energy, reduce grid reliance, and shield the business from volatile energy prices. It becomes a commercially sound decision, not just an environmental one.

RENEWABLE ENERGY

ENVIRONMENTAL LEADERSHIP AND BUSINESS CONTINUITY There’s also a proactive dimension to this shift. Many businesses are now looking beyond immediate cost savings and taking decisive steps to reduce their carbon footprint as part of a broader decarbonisation strategy. For these organisations, the move to on-site renewables and smart energy systems is as much about environmental leadership as it is about operational efficiency.

Another compelling case for commercial solar can be found in business climates where an interruptible power supply is paramount. As aged grids become increasingly unreliable, deviations and other disturbances to electrical supply are more common.

For a busy factory or manufacturer, the result of even a few minutes downtime can be huge in terms of the loss to productivity and revenue impact. Solar, combined with energy storage, provides a buffer – ensuring continuity of critical systems and reducing dependence on the national grid.

CHOOSING THE RIGHT SOLAR SOLUTION Once the case for solar is made, the next step is specifying the right solution. Structural capacity is often

the first concern. As many as 40% of commercial buildings in the UK can’t support the weight of traditional solar panels. Fortunately, advancements in lightweight, ultra-thin film technology now make solar viable for buildings previously deemed unsuitable.

Scalability is another key factor.

As the world moves towards future decarbonisation, it is becoming increasingly difficult for commercial and industrial users to predict what loads they may require a year from now, never mind in five years’ time when new electric fleets or new production technologies might have been added to the mix. In this vein, the ability to grow, support commercial objectives and scale up as needs increase is essential.

Digitalisation also plays a pivotal role. From system monitoring and energy optimisation to leveraging data analytics and AI, smart energy systems are transforming how businesses manage consumption and emissions.

Energy storage supports this digital shift, enabling informed control of usage based on real-time insights. In this way, any solar solution should complement existing infrastructure while aligning with broader smart building ambitions.

A STRATEGIC IMPERATIVE

accelerating, driven by renewable adoption and changing consumption models. While this brings complexity, it also creates a strategic opening for businesses to redefine how they generate and use power.

In this way, solar should be viewed as far more than a cost-saving measure; it’s a strategic asset. Early adopters often gain reputational advantages, better resilience against price volatility, and stronger alignment with customer and investor expectations.

The truth is, the most significant benefits from solar come with long-term use. Each year of delay represents lost savings and missed emissions reductions.

So, when is the right time to invest? In short: now.

RENEWABLE ENERGY

THE ENERGY OF THE FUTURE – HOW NUCLEAR IS PLAYING A VITAL ROLE IN THE UK’S DECARBONISATION EFFORTS As the UK continues its journey towards Net Zero by 2050, nuclear energy is emerging as a critical source of clean, reliable power. The industry currently delivers £5bn in direct spend and £4.9bn in GVA to the North West economy and is projected to triple to £15bn by 2030.

With the increasing growth of the nuclear sector and emphasis on hydrogen power, Martin O’Rourke, Commercial Director at Birchwood Park, shares how the North West’s nuclear industry is shaping the future of clean energy solutions, with strategic investment and cross-collaboration.

NEW TECHNOLOGIES Advancements in Small Modular Reactors (SMRs) and next-generation fission reactors are paving the way for more efficient, flexible, and cost-effective solutions across the industry. This is furthered by the government’s recent commitment to removing barriers to nuclear expansion, allowing for greater flexibility in site selection and streamlining planning regulations.

It signals a shift from simply replacing legacy infrastructure, to reshaping the nuclear landscape through innovation.

Technologies like SMRs address some of the biggest challenges the renewable energy industry currently faces in the transition to a net zero power system. They offer a means to decarbonise energy-intensive industries whilst providing a consistent baseload power to complement weatherdependent renewables. This grid reliability will be key in preventing energy shortages during periods of low renewable generation.

The North West is at the forefront of nuclear research and development and is home to nearly 50% of the UK’s R&D efforts.

Birchwood Park plays a crucial role in this – housing industry leaders like the UK National Nuclear Laboratory, Amentum, Cavendish Nuclear, Rolls-Royce SMR, and Nuvia.

NUCLEAR’S ROLE IN HYDROGEN Hydrogen is increasingly gaining momentum as a solution for the decarbonisation of heavy industry, transport, and heating – and nuclear energy is set to play an important role in the production of low-carbon hydrogen.

Currently, renewable-based hydrogen faces the same challenges as the wider

28

renewables industry, relying on sources like wind or solar which are fluctuating.

Scaling up hydrogen production will require a stable, low-carbon energy source, and nuclear is uniquely positioned to deliver this demand. Nuclear-produced hydrogen offers a stable, more predictable supply of power – allowing industries to commit to scaling up without the worry of intermittent production challenges.

The integration of nuclear within hydrogen projects also strengthens the case for a whole-system energy approach, in which energy storage solutions are reliable and thus able to effectively complement renewable generation. This ability to produce low-carbon hydrogen at scale will be pivotal in the UK’s net zero journey, and the North West is already leading the way in driving innovation across these projects.

ECONOMY AND JOBS GROWTH The North West’s nuclear sector supports more than 13,000 direct and 100,000 indirect jobs, and employment in the industry is expected to grow by 49% by 2030. As the industry expands and shifts towards Net Zero, ensuring that the workforce keeps pace with this demand will be essential.

Collaboration between the public and private sectors is key to addressing the industry’s skills gap and developing a future-ready workforce. The Northern Nuclear Alliance (NNA) is playing a pivotal role in tackling these challenges, connecting nuclear companies with government, regulators, universities, and training providers to align skills development with the sector’s needs. By strengthening these partnerships, the industry can build a

ENERGY MANAGER MAGAZINE • JUNE 2025

pipeline of skilled professionals capable of delivering the next generation of nuclear energy projects, aligned with the wider industry’s sustainability objectives.

In line with the immediate talent needs of the nuclear industry, bridging the skills gap will be fundamental in the UK’s wider decarbonisation goals. Ensuring a diverse, highly skilled workforce will only accelerate the introduction of low-carbon technologies, and allow the UK to advance its research in areas like nuclear, hydrogen production, and energy storage. Birchwood Park’s role as a hub for knowledge sharing and skills development will be crucial in supporting this – providing essential infrastructure for decarbonisation professionals.

The UK’s nuclear industry is at a defining moment. It is no longer solely about large power plants, it is about new technologies that are making nuclear more flexible, scalable, and sustainable.

However, for the industry to actualise Net Zero, ongoing investment, policy support and public trust will be essential.

A holistic approach to nuclear development must remain a priority, ensuring next-generation technologies work alongside renewables and complementary projects like hydrogen production. At Birchwood Park, we see first-hand how collaboration fuels the industry, as organisations based here continue to lead the way in shaping the future of clean energy. The foundations for growth are already in place and it’s about ensuring we have the talent, investment, and innovation to make it happen. www.birchwoodpark.co.uk/ destination/nuclear-hub/

HEAT PUMPS

HEATING UP THE UK’S TRANSITION TO ZERO-CARBON BUILDINGS: 5 KEY ACTIONS

H

eat pumps are the core of decarbonising the UK’s building stock. Their superior efficiency means they require 3-4 times less energy than gas boilers and electric resistive heating and can deliver clean heat and comfort to households, with the potential to lower energy bills.

Deployment has remained stubbornly low and far behind European peers – but is the tide starting to turn? In March, a record 4,000 applications were submitted for the government’s grant for £7,500, which can meet 60-95% of the cost of buying and installing a heat pump. This reflects a loosening of requirements for cavity wall and loft insulation, and a relaxation of planning policy to allow installation within one meter of a neighboring property. These are welcome developments; deep insulation is not essential for heat pumps to provide equivalent heat and comfort as a gas boiler – the Energy Transitions Commission’s report, Achieving ZeroCarbon Buildings, busts this myth.

But we are far from where we need to be. Buildings account for 40% of the UK’s carbon emissions. To meet the government’s target of reducing emissions by at least 68% by 2030 (compared to 1990 levels), it is targeting 600,000 installs a year by 2028 – that’s a 10-fold increase from today.

This is achievable – but with less than three years to go, policy needs to act fast. There are five key priorities.

• Firstly, the government must provide investment certainty. The Future Homes Standard – regulations on “zero-carbon ready” new buildings – was due to come into effect in 2025 but is still yet to be announced. The government should announce an immediate ban on gas boilers in new homes, and a ban on their sale in existing buildings from 2035. This is critical to scaling the heat pump market, lower upfront costs and build local supply chains and skills.

• Secondly, it is imperative that gas and electricity prices are

Hannah Audino, Buildings Decarbonisation Lead at the Energy Transitions Commission rebalanced to actively incentivise heat electrification. In the UK, a kWh of electricity costs four times more than a kWh of gas, virtually eroding the efficiency benefit of heat pumps on energy bills.

In comparison, in Norway and Finland, gas and electricity cost virtually the same; as a result, there are 50-60 heat pumps installed per 1,000 households a year, compared to less than 5 in the UK. • A two-pronged approach is needed. The government must remove levies which are currently disproportionately applied to electricity; revenues from carbon pricing can compensate.

Alternatively, they can be passed – gradually – onto gas, with revenues used to finance heat pumps for lower-income households. This must be underpinned by a welldesigned power market that ensures electricity prices better reflect the proportion of low-cost renewables installed on the UK’s grid.

• Thirdly, the government must continue to fund its heat pump and energy efficiency grants beyond 2026. Over the medium-term, subsidies should target lowerincome households. For other households, the government should offer low-cost finance at zero-interest rates. Banks also have a role to play through mortgage top-ups at favourable rates; there is increasing evidence that heat pumps and energy efficiency improvements augment a property’s value.

• Fourth, a coordinated and locally led approach is needed, involving local government, energy and

network companies, and businesses.

Street-by-street decarbonisation strategies can coordinate upgrades to local distribution networks, invest in local skills, and serve as a onestop-shop to streamline installation.

Crucially, they should identify where networked ground-source heat pumps can be deployed; these are 4-5 times more efficient than gas boilers, serve entire blocks of flats or streets, and are financed by the private sector (repaid through a standing charge) and so reduce the upfront cost for households.

• Finally, one of the biggest challenges is incentivising landlords to install heat pumps instead of resistive heating; heat pumps cost 4-5 times more to install, but cost households 3-4 times less to run. This is imperative both for electricity grids and supporting lower-income households in the transition. The government should implement its proposals to ensure rental properties have a minimum Energy Performance Certificate rating of C by 2030, and provide low-cost finance that is repaid directly through rental income.

It is entirely feasible to fully disconnect the UK’s buildings from the gas grid by 2045, at the latest, while lowering energy bills and improving living standards. But achieving zerocarbon buildings will not be easy – millions of individual households must be incentivized to make changes to their home that, in many cases, have a sizeable upfront cost. This requires strong national ambition, a clear role for the private sector, and unwavering policy. www.energy-transitions.org

HEAT PUMPS

RINNAI: DELIVERING EFFICIENT HEAT PUMP SYSTEMS BEYOND MEDIA PERCEPTIONS Rinnai’s Chris Goggin looks in-depth at public information regarding heat pumps and other low carbon products being potentially diluted by recent changes to social media’s stance on factchecking. The alternative heating and hot water technologies are receiving some adverse media coverage due to misinformation and sometimes disinformation. Installations of any heating and hot water – or air-cooling system, due to their very nature, must be based on accurate site information to facilitate a precise system that delivers the required performance.

C

hanges in the fact-checking status of the major brands of social media could lead to unwelcome impact on the stringent fact-based userconditions needed when installing or designing heating and hot water delivery systems. Major social media outlets have publicly reduced their commitment towards fact-checking, which could lead to accredited and trusted sources of information and data being devalued.

As UK usage of heat pumps, and other low carbon technologies, continues to grow, current public knowledge regarding alternative DHW and heating is not at a satisfactory level of comprehension. And because of poor levels of public understanding many customers who require low carbon energies and technology often order solutions that are not suited towards property requirements.

Rinnai’s objective is to equip the UK customer with product and complete system data that demonstrates the accurate value of overall system performance. One such

30

methodology of understanding is SPF (Seasonal Performance Factor).

Heat pump efficiency is measured using Coefficient of Performance (COP). The coefficient of performance (COP) is a measure of the efficiency of a heat pump, defined as the ratio of useful heat produced from the energy used. Essentially, it is a measure of how effectively a system converts energy into heating.

ENERGY MANAGER MAGAZINE • JUNE 2025

An additional measurement extensively used in the industry is the

HEAT PUMPS

Seasonal Coefficient of Performance (SCOP), which is the average COP over a full heating season. Unlike the Coefficient of Performance (COP), which presents an outline of the heat pump’s efficiency at a definite moment, SCOP takes into account the variable outdoor temperatures and operating environments throughout the season.

This method provides a more realistic picture of how effective the heat pump will be on an annual basis.

Due to the limited knowledge regarding the entire system in many commercial buildings these measurements can sometimes lead to a perception of underperformance of the heat pump system. This in turn lowers customer expectations, damages the reputation of heat pump technology and lowers confidence within the specification process. The lack of congruence between the expected heat pump performance and actual system performance can only be overcome by a complete system thinking approach.

SCOP calculations do not take into consideration the various additional factors that occur daily during heat pump operation. This could include immersions

operating for large, high heat loss recovered by backup heaters, system pumps or ancillaries within the secondary system utilizing excess energy.

To account for these losses research has been conducted to calculate the SPF of a heating system.

Over the period of a year this measurement evaluates the overall heat supplied to the total electricity used as the outdoor temperature fluctuates. The SPF accounts for many additional variables that can only be accurately understood by installing data loggers to effectively monitor the system and show an accurate image of hourly operations.

Join the free CIBSE accredited SPF CPD today https://www.rinnai-uk.co.uk/ training/cibse-cpd-training-enrolment Nevertheless, these calculations can also be used from a design point of view prior to installation. Estimates can be made that may differ from real-time operation yet provide the customer with a clearer picture of how their system will perform throughout the year. Post installation, data loggers can

be attached to verify this design SPF. As current social media is now creating distance between audience and fact, UK contractors, installers and all other customers should prioritise manufacturers of carbon reducing technology who present technically led data that demonstrates system efficiency. One of Rinnai key objectives is to provide customers with accurate, consistent, and transparent product data the makes decision making easier.

COMMERCIAL HEATING: CHOOSE YOUR TRAINING WISELY! Andrew Johnson, Training & Design Services Director, Ideal Heating Commercial

T

raining has always been important in the heating sector, not least of all because of the dangers associated with working with gas, the traditionally dominant heating fuel in the UK. With the changes that are occurring across the heating industry, primarily the move towards decarbonisation manifesting in a transition to heat pumps, training is more important than ever. That training could take the form of a CPD on understanding the principles of heat pump technology through to specific product training addressing installation, commissioning, and maintenance.

Commercial heating training courses are abundant. Unless there is a specific manufacturer’s product you want to train on, how do you choose a training course and provider that is right for you? Here, we look at the key aspects to consider when selecting a training course and training provider.

EXPERTISE & KNOWLEDGE By far the most important aspect of any training is the level of expertise and knowledge of the training providers. The training course needs to be both written and delivered by people who have direct experience in the heating industry. Knowledge or qualifications in training techniques and knowledge transfer is as equally important.

For contractor-based training, ideally the trainers will have a background in heating engineering. This enables them to not only cover the core content of a training course but also address how it applies in real working-life situations.

For specifiers looking to expand their knowledge through CPD courses, it’s helpful if these are presented by experienced Specification Managers who understand the needs of a specifier and have extensive knowledge of heating systems.

ON-SITE FACILITIES The environment in which you learn plays an important role in the success (or otherwise) of the training itself, which is often overlooked.

Being in a comfortable environment free from distractions will support you to better focus on your learning. Is the training held in a dedicated training centre or a makeshift back office room? Is it a comfortable environment in terms of seating, desks, heating/air conditioning? Is the presentation equipment up to scratch? But most important of all, is

the heating equipment you are learning about present, and is it functional?

At our Training and Technology Centres, we provide learners with onsite access to a range of commercial heating equipment, including a unique thermodynamic heat pump simulator where they can view the change of state of refrigerant when in operation. Handson training for contractors is vital as it enables more learning by doing and problem solving, and therefore greater depths of understanding can be gained. In our feedback surveys this comes up as one of the most important and popular aspects. It’s one thing to have something presented to you, but to be able to work through scenarios with expert support is quite another.

LOCATION We’ve looked at the importance of how a training course is delivered, but where it is delivered also has a role to play.

Does the training provider have training facilities nationwide, or in just one location?

The latter could make for long travel times and even an overnight stay. Ideal Expert Academies are located around the UK at Hull, Leeds, Dalgety Bay and Luton.

Lastly, not all training needs to be done in person. A CIBSE-approved CPD, for example, doesn’t require handson training. In these instances, online training is a good, convenient option. Will the training provider be able to deliver this and how? Is it just a PowerPoint presentation, or are other elements included such as video, attendee tasks etc?

RANGE OF COURSES AND DELIVERY Having a range of courses is obviously important in that it provides you with choice and allows you to fill in the gaps of your knowledge, as well as learning about emerging technologies and best practice.

A good training provider will also provide a flexible delivery model to meet individual learner needs and has the knowledge and expertise to support those with learning difficulties.

ENDORSEMENT Whilst it’s important to do your own ‘homework’ on training providers, third party endorsements are very useful. These

Expert Academy Training Team

come in different forms, from customer feedback (there are plenty of forums that provide you with the opportunity to ask for feedback), through to recognised industry awards, and independent assessment.

Last year, Ideal Heating’s adult learning provision was assessed by Ofsted and we received an excellent report, plus our Expert Academy team was recognised as Training Partner of 2024 by Hull City Council for delivering Skills Bootcamp programmes for hundreds of learners in the area. We were also delighted to receive the inaugural BESA award for Training Provider of the Year 2024.

COST The last aspect I want to touch on when it comes to training is cost. How much should you pay for training? You should really consider the value you believe will be returned from the programme and provider you choose. If you are going to benefit from state-of-the-art facilities, you may probably expect that that experience may cost more than somewhere very simple and basic. Training providers are businesses, and the good ones do invest heavily in facilities and staff development.

Ideal Heating as a manufacturer strongly believe that our training services are part of what we deliver in our product sales. For this reason, we provide many of our training programmes for free or at very low cost, despite the significant investment into our resources. Working alongside our specifiers and installers to meet their training needs builds for a strong relationship and successful projects.

CHOOSE WISELY Taking time out from your busy schedule to dedicate to training is an investment, financially in some cases, so selecting your training course wisely to maximise that investment is sensible.

STEAM SYSTEMS

DISPELLING MYTHS: STEAM’S ROLE IN A NET-ZERO FUTURE When it comes to decarbonisation, steam often gets a bad reputation.

T

here’s a growing misconception that to achieve net-zero, industries must move away from steam entirely – a process sometimes dubbed “desteaming.” But here’s the truth: steam isn’t the problem; It’s the fossil fuels that have traditionally been used to generate steam that are.

In fact, with the right updates and technologies, steam systems can play a central role in a low-carbon future.

At Spirax Sarco, we believe it’s time to set the record straight.

Myth: Steam is Outdated and Incompatible with Net-Zero Steam has been the backbone of industrial heating for over a century. It’s trusted, efficient, easy to control and distribute and incredibly versatile – which is exactly why it’s still widely used across sectors like food & beverage, healthcare, pharmaceuticals, and manufacturing.

What’s often misunderstood is that steam systems themselves aren’t inherently inefficient. It’s how they’re managed, maintained, and powered that makes the difference.

Fact: Steam Can Be Decarbonised – Without Being Replaced Modern steam systems are nothing like those of decades past.

Today, businesses can make huge strides towards net-zero while continuing to use steam, by adopting smarter, cleaner practices such as: • Electrifying steam generation using renewable electricity • Installing energy-efficient components like precision control valves, insulation, and flash steam recovery systems • Digitally monitoring steam traps to prevent losses and keep systems running at peak performance

• Recovering waste heat to reduce overall energy demand These solutions don’t require a complete overhaul. They work with the existing infrastructure you already have – and they deliver measurable savings in both emissions and operating costs.

WHY “DESTEAMING” ISN’T ALWAYS THE ANSWER Removing steam entirely often comes with unintended consequences: large capital expenditure, longer payback periods, costly and intrusive building, pipework and process modification and the introduction of alternative systems that may still rely on fossil fuels at some stage of the process.

For many businesses, it’s far more practical – and sustainable – to optimise what’s already in place.

At Spirax Sarco, we’re helping customers decarbonise without compromising performance, safety, or reliability. Whether it’s a dairy looking to cut emissions or a hospital needing

guaranteed sterilisation, steam remains one of the most effective ways to deliver heat – especially when it’s used wisely.

THE BOTTOM LINE Ditching steam isn’t a prerequisite for going green.

With the right upgrades, maintenance, and control, steam systems can absolutely support your decarbonisation strategy – and in many cases, outperform newer alternatives in both efficiency and environmental impact.

The FIRST step is to reduce demand for steam by following best practice with steam generation & distribution and then seek to understand the process.

Let’s stop writing steam off – and start working with it to build a cleaner, more sustainable future.

MONITORING & METERING

Ever heard the phrase “You can’t manage what you can’t measure”?

It’s often attributed to quality and process control guru W. Edwards Deming and management consultant Peter Drucker. Neither really said it, but this expression raises an important point.

Consider facilities managers (FMs). How can they improve energy efficiency if they can’t monitor energy use? Here Dave Lister, healthcare solutions specialist at IAconnects, a specialist in IoT monitoring solutions, explains how monitoring energy consumption in real-time can improve sustainability and reduce costs.

R

ising energy costs, ambitious net-zero targets and increasingly stringent regulations have all made energy efficiency a top priority for businesses. The Streamlined Energy and Carbon Reporting (SECR) requires large organisations in the UK to report their energy use. They must also provide information about their carbon emissions. This reporting happens every year. Similarly, under The Energy Savings Opportunity Scheme (ESOS), companies must regularly audit energy consumption and carbon emissions.

Energy monitoring is important for understanding this complex situation. It helps businesses manage their energy and electricity use effectively. Real-time insights can help

36

DRIVING ENERGY EFFICIENCY WITH DATA

businesses find inefficiencies, save money, and lower their carbon footprint.

This supports their Environmental, Social, and Governance (ESG) goals.

and energy-wasting habits, such as forgetting to turn the lights off.

Monitoring is the first step and will help determine the required interventions.

We always say, consider the four C’s: Compliance, Consumption, Cost and Conservation. As well as meeting regulatory requirements, energy monitoring helps deliver in all these areas while driving real efficiency progress.

Energy monitoring also facilitates proactive maintenance, identifying potential issues before they escalate into costly repairs. For example, abnormal consumption patterns can signal malfunctions in electrical equipment, allowing teams to address problems early and maintain optimal performance. Meanwhile, FMs can tailor their monitoring to different levels of granularity, from meter to asset level. This flexibility is crucial, it enables businesses to maintain precise control over energy use and ensure efficient operations across entire facilities and individual departments.

THE BENEFITS OF MONITORING Energy monitoring empowers businesses, offering real-time insights into inefficiencies and the amount of electricity they produce across operations. By analysing consumption patterns, FMs can find trends and spot areas with high usage. This includes old HVAC systems, outdated lighting

ENERGY MANAGER MAGAZINE • JUNE 2025

MONITORING & METERING

THE CHALLENGES Introducing energy monitoring systems can be complex, with several hurdles. A prominent issue is the compatibility of new systems with legacy infrastructure, which may require costly upgrades or workarounds. The installation can also be challenging and intricate, with FMs trying to navigate budget constraints and keep operational disruptions to a minimum.

Data overload can be a problem for businesses. They may find it hard to tell useful insights from irrelevant data. This issue is made worse by gaps in their internal expertise. To overcome these barriers, organisations should invest in scalable, future-proof solutions that adapt to evolving needs. Partnering with

an experienced provider ensures systems are seamlessly integrated and delivers meaningful insights to maximise results.

LEVERAGING TECHNOLOGY FOR EFFICIENCY Modern energy monitoring solutions, such as IoT sensors, submetering systems, and real-time dashboards, provide detailed insights that drive efficiency. These tools enable predictive maintenance, automate optimisation strategies like HVAC adjustments, and help manage peak loads to prevent energy spikes.

Choosing interoperable systems with open communication standards enhances data integration, giving FMs a comprehensive view of energy

consumption. Using these tools with current building management systems (BMS) improves the data available. This helps FMs make informed decisions that support net-zero and ESG goals.

Energy monitoring truly exemplifies the principle, “You can’t manage what you can’t measure.” By enabling realtime insights and actionable energy data, businesses can reduce energy bills, improve sustainability and meet compliance requirements.

ARTIFICIAL INTELLIGENCE

GLOSS OR GAME-CHANGER? AI IN NON-DOMESTIC DECARBONISATION

W

hat do we mean by ‘Artificial Intelligence’ (AI)? It seems like every software solution nowadays boasts that it uses AI, but, as with other buzzwords like ‘sustainability’ or ‘digital twin’, what people mean by it and how people interpret it varies hugely.

This can be a problem when it comes to procuring and using AI tools. If what users think of AI as being differs from how it actually works, then real world decisions can be made based on flawed assumptions and misplaced confidence.

In the course of our work with non-domestic energy data and supporting Net Zero innovators, we have spent time working with AI experts to understand how the market is evolving, what AI products are available and how they deliver.

The question we want to address is: How can you tell whether a particular AI solution is appropriate for your situation?

COMMENT

by Craig Mellis, Senior Advisor- Decarbonisation of Complex Sites, and Samuel Young, Practice Manager – AI, at Energy Systems Catapult other ‘large language models’) essentially works by answering the question “what are the most likely words to come next?”.

It is focused on words and what is most commonly written, rather than underlying data and facts, so the answers it gives are usually plausible but not always grounded in fact. When you hear software “uses AI” and the software involves documents or a chatbot, this is probably what it means.

Predictive AI analyses more structured data, often in a spreadsheet or database, and looks for patterns in that data. When you give it new data, it compares that data to the patterns it found in previous data and suggests things that might also be true of this

new data. You may sometimes see this referred to as machine learning (ML).

This is a bit more grounded in data and facts, but it is still only extracting patterns from past data, so if the data is incomplete or the future is quite different from the past, then it won’t necessarily give the right answers.

APPLYING AI TO HEAT DECARBONISATION PLANS Let’s look at an example to illustrate this. Consider the case where we want to develop heat decarbonisation plans for sites or buildings based on previous heat decarbonisation plans for similar sites or buildings.

ARTIFICIAL INTELLIGENCE A generative AI approach would feed the existing pdf-based heat decarbonisation plans into a ChatGPTtype tool which might then generate pre-populated decarbonisation plans for new sites. However, because the approach is “what text is most likely”, these new plans will tend to be based on the most common applications and recommendations, with a thin veneer of site customisation, rather than reliably understanding the needs of each site and customising plans accordingly.

A predictive AI approach would take a wide range of structured information about a site (e.g. location, building areas, energy usage) and use similar information from other sites to find correlations and make recommendations. It is more likely to recommend approaches that have been pursued at similar sites and remove options that are clearly unsuitable for a site from examination of the data.

Of course, neither can compete with the nuance and detail available from a site-based walk around and audit (“Phew!” I hear some of you engineers say) but the second is likely to provide a better suggestion of the options which could be then investigated whereas the first may well provide spurious results that are less useful.

It is also important to recognise that neither approach is ever going to be more accurate than its input data.

An AI can only go on the information it has been provided with, and if that information is insufficient or incorrect it will make incorrect recommendations – usually without alerting the user to the fact key information is missing/wrong!

This is where engineers and people who really know the site really shine – they can much more reliably spot when something isn’t accurate or realistic for a site.

In some cases, hybrid approaches combining different types of AI may be more effective. For example, generative AI may be able to extract structured data from text for a predictive AI approach to use (e.g. “Does this decarbonisation plan involve solar PV?”) or turn the output of a predictive AI model into more user-friendly text.

When developing building decarbonisation plans: • Generative AI is less likely to provide reliable insight about specific sites • Predictive AI with access to structured data about lots of buildings may be able to group buildings to help identify and prioritise investigation and action • Expert knowledge will still be required to tailor a plan to each site

DOES AI ACTUALLY HELP US? Well-chosen AI tools can be a powerful force in helping us pick up the pace in getting our wide and varied non-domestic estate to Net Zero. However, reliance on AI tools that are inappropriate for the task also has the potential to undermine good decision making and slow us down.

To ensure we use AI appropriately it is important to: 1. Understand what a specific instance of AI is, and is not, capable of (you may sometimes need support from people with greater AI knowledge for this).

2. Evaluate whether the data provided to AI contains enough of the important information for the AI to make reasonable recommendations.

3. Define a small number of detailed examples that you can use to test how reliable an AI’s outputs are.

4. Ensure human expert knowledge is applied after or alongside AI recommendations, rather than following them blindly.

HOW EV CHARGING ENGINEERING CAN HELP SUPPORT THE GOVERNMENT’S AMBITION TO INSTALL 300,000 CHARGE POINTS BY 2030 AND OVERCOME EXISTING CHALLENGES Robert Nash, CTO, Petalite

A

pproaching 2030, to meet both government and consumer demands around electric vehicle (EV) adoption, we are likely to see a much greater push to rapidly scale up EV charging infrastructure, making it more reliable and more accessible for a greater number of drivers.

While sustainable transport policies must include public transport, cycling, and other zero emission vehicles, it is also vitally important to recognise and support the challenges involved in switching from ICE vehicles to EVs. To put this into context, as of the 1st May 2025, there were around 79,000 public EV charging points, meaning that for the government to meet its 2030 goals of at least 300,000 charge points, an additional 221,000 will need to be installed in the next five years. With nearly 1.5 million electric vehicles (EV’s) currently on the UK roads, and 52% of drivers saying they are likely to choose an electric vehicle for their next car, changes are needed to meet the needs of current and future EV drivers. With the ZEV mandate banning new petrol and diesel car sales by 2030 (and hybrids by 2035), EV numbers on UK roads are set to rise sharply. However, research suggests that inadequate charging infrastructure within the UK is hindering EV adoption, creating ‘charging anxiety’ and discouraging petrol and diesel drivers from making the switch.

LESSONS LEARNED Countless charge point technology lessons have been learnt so far, including the need for more reliable and rapid charge points. Occupied stations, technical difficulties, and payment issues are among the public charging issues that over four fifths (83%) of UK EV drivers have struggled with in the past 12 months.

As EV adoption grows, the 32.8% of UK households (9 million) who do not have access to a driveway means an increase in the number of people reliant on the public network. This has created ‘charging anxiety’ with drivers concerned about when and where they will be able to charge their vehicle.

To further compound the issues affecting EV drivers, those relying on public charge points currently pay 20%

VAT compared to the 5% charged for domestic energy, highlighting huge price discrepancies. It is clear that for the industry to succeed things needs to evolve, both in terms of technology and regulation.

Recent research shows public EV charging satisfaction is around 64%.

Charge point operators see clear potential to improve the driver experience – boosting loyalty and revenue.

INVESTMENT Within the market, charge point operators (CPOs) are looking to their hardware manufacturers to lead the transition and deliver the technical innovation that the industry needs in order to meet the government ambition and driver expectations. To assist with the EV uptake that the government is targeting, CPOs will be required to improve reliability, charger availability, charging speed, user experience, scalability and modularity, installation and maintenance, as well as access to grid connection across their sites.

To help meet the government’s expectation, and to encourage more people to switch to EV vehicles, investment in more reliable rapid and ultra rapid DC charges will also be required. A long-term fix is needed.

DELIVERING AN EFFECTIVE SOLUTION To help solve expansion problems and to address the pain points being experienced Petalite has developed and patented a future-proof technology solution,

sinusoidal direct current which simplifies AC-DC conversion. This technology ensures that power from the AC three phase supply from the grid is balanced through a single conversion stage, performing power factor correction, rectification, galvanic isolation and current regulation. This enables next generation power distribution capabilities to provide a better charge point to site power ratio and give the best possible charging speed available to drivers. This solution has the opportunity to truly overcome current barriers in the EV transition and deliver future proofed EV charging infrastructure.

To reduce ‘charging anxiety’ and to accelerate the rollout of EV adoption drivers require simplified technology, reliable charge points and scalable infrastructure that can easily grow in line with demand, all of which the Petalite solution has the ability to provide.

Deciding the rate at which infrastructure needs to be scaled up at is a major challenge CPOs are facing. Whilst a growing network of charge points will encourage more drivers to switch to EV’s, in order to justify investing in more infrastructure, CPOs will need to feel confident that the demand is already there. Having futureproof technology that consistently works, optimises site power and considers user experience will help to demonstrate the value of driving an EV, and should help to encourage drivers to make the switch.

In-turn CPO’s will be motivated to invest in infrastructure, creating a virtuous circle and a more harmonious balance between supply and demand. https://www.petalite.io/

RINNAI – KAIZEN & KANBAN PRINCIPLES DELIVER MARKET LEADING QUALITY Chris Goggin explains the approach to the relentless pursuit of manufacturing excellence, including the two separate methodologies of “Kaizen” and “Kanban,” that are central to Rinnai manufacturing excellence.

J

apanese manufacturing industries are acknowledged as global leaders in innovation, efficiency, and product durability and longevity. Japanese companies have consistently maintained their competitive edge and endured the test of time. As many use the “Kaizen” and “Kanban” approach to manufacture.

These are two distinct methodologies that are adopted into the daily operations of Rinnai, and they ensure the highest levels of manufacturing standards. The term ‘Kaizen’ has come to mean “continuous improvement,” in a professional context. A broader interpretation can be translated as

42

continuous improvement in personal life, home life, social life and working life.

A Kaizen approach focuses on implementing gradual and incremental changes that will produce long-term improvements in professional efficiency and quality. The main principles that facilitate the concept of Kaizen are: • Know Your Customer • Let it Flow • Go to Gemba • Empowering People • Be Transparent

ENERGY MANAGER MAGAZINE • JUNE 2025

“Know Your Customer” identifies what is truly required by the customer to deliver an enhanced end-product that satisfies demand.

• “Let it Flow” concentrates on creating a smooth flow of processes and practices that identifies and eliminates production bottlenecks whilst reducing customer waiting times. This principle focuses on eliminating waste in all aspects of the commercial operation – waste is viewed as any culture or practice that does not benefit the customer or encourage professional productivity.

• “Go to Gemba” translates as being always concerned with all matters in every department.

• “Be Transparent” uses and measures data that improves company progress.

• “Empower People” relates to providing appropriate tools to successfully complete group targets that maximise production efficiency.

Kanban is a philosophy that seeks to encourage continuous improvement

SHOWCASE in production and business methods by measuring project progress through visual Kanban boards. The Kanban methodology was invented by Toyota engineer Taiichi Ohno during the late 1940s. The term “Kanban” when broken down into two words from Japanese to English means “Kan” (sign)” and “Ban” (board).

A Kanban approach was employed to improve Toyota’s production system by incorporating elements of lean manufacturing into their process. Kanban framework allowed Toyota to transition from a “push” process (products are pushed on to the market) into a “pull” system (products that are created due to market demand).

This idea allows companies to risk low inventory levels whilst remaining competitive.

Kanban is also referred to as the “Just in Time” (JIT) system, as production can concentrate on creating products because of consumer demand as opposed to manufacturing products that rely on anticipated demand.

Kanban boards are organised into columns – each column contains visual cards that represent a task during a separate stage of work. The team can easily track task progress and share necessary information that assists in task completion. Kanban boards are an agile and fluid visual form of measuring group progress during the completion of a task.

The creator of the Kanban framework Taiichi Ohno maintains strong links to Rinnai and has had a discernible influence and impact on Rinnai’s production system. Ohno visited Rinnai’s Japanese production plant and provided critical observations and advice that led to Rinnai adopting lean manufacturing principles that enhanced product producing efficiency.

Both Kaizen and Kanban frames of thought assist Rinnai’s manufacturing process that delivers millions of products per year all manufactured under strict guidelines of ISO 9001 quality management and ISO 14001 environmental management systems.
