GRIDSERVE lands new batteries at London Gatwick Electric Forecourt®

UK Power Networks has connected a new battery energy storage project at London Gatwick electric vehicle charging station.

GRIDSERVE and UK Power Networks have connected a new Battery Energy Storage System to the electricity network, supporting EV charging at London Gatwick Electric Forecourt®.

Two 3.6 megawatt SYL batteries have been connected to UK Power Networks’ distribution network. The batteries can supply EV chargers from stored electricity at peak times, to support EV charging, lower carbon emissions and efficiently use the grid.

London Gatwick Electric Forecourt® opened last year on the South Terminal with 30 bays, providing a strategic charging hub for the airport’s passengers, staff, taxi fleets and the local community in line with the country’s Net Zero ambitions. The new batteries can power the whole site for three hours at full capacity.

The forecourt building also has a 33.3kW solar panel system on the roof with 114 panels to supplement the power needs of the shops and facilities at the site.

Network connection design and delivery teams at UK Power Networks worked closely with GRIDSERVE to commission the new network. This included a voltage management scheme at the grid substation and adoption of the 33,000-volt network to the customer’s site. It also connected transformers for auxiliary power at GRIDSERVE’s electricity substation.

Raoul Tufnell, Development Director at GRIDSERVE, said: “Through a great collaboration with UK Power Networks, we are thrilled to connect our Battery Energy Storage System at London Gatwick Electric Forecourt®. The new batteries support not only on-site demand from our chargers and building but also can provide grid services for the electricity network. This is the fourth Electric Forecourt within UK Power Networks’ geography and a fantastic statement for how GRIDSERVE, working closely with UK Power Networks, is contributing to a greener future for the UK.” 

Tosin Abimbola, major connections project manager at UK Power Networks, said: “We were delighted to energise the battery storage system at London Gatwick Electric Forecourt® to support EV charging alongside one of the UK’s busiest airports.

“We strive to make it easy to connect low carbon technologies to our networks and are proud to continue collaborating with GRIDSERVE on the UK’s journey to Net Zero.”

UK Power Networks maintains the network of cables, substations, and power lines that deliver electricity to 8.5 million homes and businesses across the South East, London, and East of England. The company also designs and delivers tailored new and altered electricity connections for developers, companies and homeowners across those regions.

Addressing the challenges facing water sector energy and carbon managers

Rosa Rotko

Rosa Rotko, project director energy transformation, Mott MacDonald

As water and wastewater companies in England and Wales embark on the next regulatory Asset Management Period, which runs until 2030, reducing carbon emissions from both assets and operations will come under spotlight.

Not only are rising energy costs and increasing needs for energy resilience front of mind – water industry regulator Ofwat has now introduced new performance commitments on operational carbon emissions as part of the 2024 price review. The rewards and penalties arising from these performance commitments will support the UK’s wider 2050 net zero target

In my role at Mott MacDonald, I engage with energy and carbon managers in the water sector who have shared some of their challenges as they seek to curb emissions significantly over the next five years. There are technical, commercial, regulatory and management issues to consider.

Putting the right technology in the right place

Foremost among the technical challenges is the problem of introducing new technologies and monitoring systems into existing sites and operating environments. Suitability of on-site renewables and storage is limited by a site’s characteristics – as well as potential objections in the planning system. Integration of water and wastewater systems with digital tools to combine energy demand and flexibility measures is also not straightforward.

The availability of key technology (e.g. solar panels, electric vehicle chargers) and expertise in the supply chain will be a barrier, and needs to be factored into the timetable. Should new grid capacity be required, timeframes are likely to be extended further, meaning that the carbon savings might not be realised until the next regulatory cycle.

Setting up adequate digital energy and carbon monitoring tools is crucial. Ofwat expects any data submitted to be subject to rigorous assurance, and companies need their own performance data to be accurate and reliable, particularly if they are engaging in demand side response and energy arbitrage activities.

Seizing commercial opportunities

The use of on-site generation and energy storage creates an opportunity to reduce operational energy costs and exposure to wholesale markets – as well as bringing down scope 2 emissions as there is less need to purchase electricity from the grid.  Looking at behind the meter and private wire solutions therefore ought to be a priority.

However, water companies operate in a regulated and cost-conscious environment that can make accessing finance more complex and limit the ability to take risks. Energy managers need to carefully build business cases, showing the full range of benefits for the regulated and non-regulated parts of the business.

In addition to the obvious cost savings, calculations of the regulatory payments or penalties under the performance commitments will form part of this. Other benefits could include revenues from offering ancillary services; avoided costs (e.g. from reduced maintenance); greater price certainty; reduced vulnerability to rising wholesale costs; and qualitative benefits such as improved reputation.

Navigating regulatory complexity

Energy and sustainability managers in water companies are having to get to grips with regulations not only in their own sector but also in the energy markets. This is bound to make execution of their roles challenging, since they work in relatively small teams and cover multiple topics.

As water companies enter this new regulatory period, it is important for Ofwat to support them with clear direction and guidance as energy transformation and decarbonisation efforts progress.

Energy markets and carbon understanding will become an increasingly important part for the regulator’s remit.

Stakeholder management is key

Increasingly, leaders and senior managers in water companies need to consider energy and carbon as part of their wider corporate vision. Decision makers need the capability to understand and debate these issues.

Energy availability and costs can contribute to a multitude of organisational goals for modernisation, efficiency and capital programmes. Senior champions with knowledge of the energy and sustainability agenda will become increasingly important in the water sector.

Stakeholder management will be key to building successful energy and carbon reduction programmes. Water companies will need to partner more with energy solutions providers, the wider supply chain and possibly community energy groups – so building networks and horizons beyond the sector will be useful.

In summary, it is in the interests of both customers and the environment that water companies take action to reduce energy costs and carbon emissions. The sector has already made significant progress and performance commitments over the next five years should be further motivation to redouble these efforts. Technical, commercial, regulatory and management challenges exist, but none are insurmountable.

Energy and sustainability managers, most of whom are doing commendable jobs, need the support from their management and the regulator to tackle these complex issues.

The Future of Heat Networks – Efficiency, Compliance and Smart Monitoring

A newly developed residential complex utilising Heat Interface Units

As the UK transitions towards a low-carbon future, heat networks are becoming an increasingly vital component of sustainable energy infrastructure. With new heat network regulations set to be introduced very soon, Behfar Abedinia, General Manager at Taconova UK, explores how efficiency, compliance and smart monitoring can shape the future of heat networks.

The Rising Importance of Energy Efficiency in Heat Networks

Heat networks offer a robust, efficient and sustainable heating solution. In its Net Zero modelling, the Climate Change Committee (CCC) showed that 18% of the UK’s heat supply will need to come from heat networks by 2050, an increase from the current figure of 2%[1], if the UK is to meet its net zero targets.

However, many existing networks suffer from inefficiency, with Government figures[2] revealing that some operate at just 35-45% efficiency due to significant heat losses during distribution. Inefficient heat networks not only increase operational costs and offer poor output but they also undermine environmental goals.

In 2023, the UK government introduced the Heat Network Efficiency Scheme[3] offering financial support to heat network operators to improve the efficiency of their networks.

HIUs for District Heating

Once you have an efficient network you need an efficient method of transferring heat to those who require it. Heat Interface Units (HIUs) are seen as a pivotal piece of equipment in district heating systems because they enable efficient delivery of heating and hot water to individual properties.

Unlike traditional boilers, HIUs connect to a central energy source, such as a combined heat and power (CHP) plant or renewable energy systems like solar or biomass. This centralised approach minimises energy loss and supports low-carbon goals. By adopting high-performance technologies like HIUs and optimising system design, heat networks can ensure efficient energy transfer and achieve significant energy and cost savings.

The Power of Data

Smart monitoring can enhance the performance of heat networks by providing real-time insights into system performance. Solutions like Taconova’s energy efficiency dashboard can offer advanced analytics dashboards that allow operators to track energy consumption patterns, identify inefficiencies and implement proactive maintenance strategies. This data can enhance reliability and reduce downtime as problems can be identified quickly and even predicted to prevent them from escalating. This in-depth level of maintenance can then help to extend the lifespan of network components.

For instance, heat meters integrated into HIUs not only provide accurate billing data for customers but also enable operators to monitor usage trends and optimise performance. These data-driven approaches are essential for modern heat network management.

The UK Heat Network Regulations

The UK is set to introduce comprehensive regulations for heat networks. These changes will transform heat networks into a regulated utility under Ofgem’s oversight, similar to gas and electricity markets. 

Key regulatory requirements include:

  • Mandatory technical standards: Networks must comply with the Heat Network Technical Assurance Scheme (HNTAS)[4], which sets minimum performance benchmarks.
  • Consumer protection measures: Operators must ensure fair pricing and transparent billing practices.
  • Compliance: Both new and existing networks will need to comply with new regulations in order to be HNTAS-certified.

These regulations aim to improve service reliability, reduce carbon emissions, and protect consumers. However, they also present compliance challenges for operators who must adapt their systems to meet the new standards.

Ensuring Fair and Compliant Operations

Accurate metering is crucial for both compliance and customer satisfaction. According to the Heat Network (Metering and Billing) Regulations[5], heat network operators are generally required to install meters on their networks, provided it is cost-effective and technically feasible, meaning they must install meters in most multi-occupancy buildings on a district heating network to measure the heat consumption of individual dwellings. However, there are exemptions for certain building types and situations which can be assessed based on cost-effectiveness analysis.

Transparent billing practices not only ensure regulatory compliance but also enhance trust between operators and consumers.

Taconova’s Metering & Billing offering provides a simple and compliant solution. These tools enable operators to provide accurate bills while also offering insights into energy usage patterns.

Taconova’s energy efficiency dashboard showing a 7-day overview

Efficient, Compliant and Smart

As the UK moves towards its 2050 net zero targets, heat networks are in position to become a primary heating solution for millions of households and businesses. The introduction of the HNTAS and Ofgem regulations means efficiency, compliance and smart monitoring will be more important than ever if heat networks are to provide the 18% heat supply the UK needs to reach its net zero targets.

At Taconova UK, we welcome the introduction of these regulations because they offer a fairer, more efficient heating solution. Our HIU and Metering & Billing experts are ready to assist operators and consumers by offering guidance on our heating technology and metering solutions to ensure a smooth transition to the new regulatory framework.

Microgrids: the Future of Energy Independence

David Rimmer

David Rimmer, Microgrid Business Leader UK&I at Schneider Electric

Despite global attempts to reduce power use, the IEA predicts that energy demand will rise by 3.4% a year until 2026, with data centres and artificial intelligence (AI) consumption likely to triple. With this increased use comes a need to secure independence, so that if something goes wrong, it doesn’t take everything down with it. This is being achieved through microgrids, which can decentralise electricity and prevent mass issues.

Microgrids are being utilised to save costs and change energy strategy in a variety of sectors. They offer a solution by enabling the transition to renewable energy sources to satisfy sustainability goals, by avoiding existing grid connection delays and congestion challenges seen in the UK and Europe.

For those less familiar with microgrids, let me run you through what they are and how they’re helping businesses and the grid today 

What are microgrids and how do they help businesses?

A microgrid is a self-contained electrical network that lets businesses generate their own power on-site. It connects, monitors, and controls distributed energy resources (DERs), improving energy performance, resilience, and sustainability.

The three key benefits of microgrids are sustainability, cost savings, and resilience. They support clean energy goals by integrating renewables and reducing fossil fuel reliance. Financially, they lower energy costs, enable peak demand management, and create revenue by selling excess energy. Microgrids also increase reliability by allowing businesses to have more control over their energy consumption.

Microgrids also give organisations more control over energy costs to optimise demand, reduce use at peak times, and store electricity.  They can reduce outage risks, preventing productivity loss, and enhance resilience by ensuring power during grid failures. Their distributed design also strengthens cybersecurity and energy security.

Relieving the pressure on existing infrastructure.

By reducing the strain on conventional networks, microgrids and energy storage give companies energy independence. Microgrids co-locate generation and consumption, producing electricity locally as opposed to centralised networks that depend on distant power plants.

By converting households and businesses into energy producers, this decentralised strategy helps alleviate grid congestion and growing energy demands. Microgrids can enable new energy uses like EV charging, smart industries, and agriculture and can be deployed more quickly and affordably than grid upgrades.

Infrastructure development must go beyond energy supply if microgrids are to become a reality. Existing grids need to be more spread out, independent from each other, and resilient to external factors to reduce building pressure. These improvements are necessary to increase microgrid capacity and storage, and industry needs to be encouraged to become grid-active and profit from local energy output.

Because microgrid integration is governed by regular networks, which frequently slow approval, connecting to the grid might be difficult. Once operational, weather-related fluctuations in microgrid supply can be avoided by on-site battery storage, which stores energy for usage when needed.

Although improvements have been gradual, infrastructure needs to advance to keep up with decentralised solutions, EV charging, and renewable energy sources. Digital twins can guarantee a successful microgrid integration and optimise current infrastructure.

The future of microgrids is now

Careful planning is essential in ensuring microgrids are a worthwhile investment. Returns on spending can be increased by working with knowledgeable partners who assess energy capacity, comprehend business factors, and provide asset recommendations.

Finland’s Citycon Lippulaiva complex is a perfect example, incorporating a microgrid backed by sophisticated digital monitoring tools and intelligent management systems. Resilience, sustainability, and operational efficiency have all been maximised in this sustainable urban development, which includes a bus terminal, metro station, shopping mall, and flats. Within five years, the microgrid is expected to return on its €3 million investment, having cut yearly energy expenses by 14%.

In order to manage the reliable, but intermittent, potential of renewable energy sources like solar and wind, microgrids must be integrated into conventional energy infrastructure in order to reach their full potential. This shift makes switching to a smart grid essential; a sophisticated, digital network that maximises power supply through automation, control systems, and two-way communication. These technologies will improve the energy grid’s efficiency, dependability, security, and sustainability as we move towards smart grids, fostering the expansion of microgrids and the integration of renewable energy sources.

New trial explores added bonus from heat pumps

The HeatNet project explores how heat pumps not only keep people warm but can also enhance the nation’s energy grid.

UK Power Networks is exploring how heat pumps not only keep people warm but can also enhance the nation’s energy grid.

This is the vision behind HeatNet, a project harnessing the power of smart technology to optimise heat pump operation as the UK works to reduce carbon emissions. By leveraging AI and machine learning to coordinate and adjust heat pump usage, HeatNet is transforming how the nation manages the growing demand for electricity, flexing energy usage without impacting customers. The innovation is being developed in collaboration with Passiv and independent experts from Imperial College via Imperial Consultants.

The UK government aims to install 600,000 heat pumps annually by 2028, up from 35,000 a year. This large-scale adoption is crucial for the UK’s carbon reduction goals but adds to the demand on the electricity grid, especially during peak times.

Building on over a decade of research in heat pump optimisation, HeatNet aims to ensure that heat pumps operate efficiently without compromising people’s comfort or requiring unnecessary infrastructure upgrades.

The project will also explore innovative ways to reward consumers for their involvement in supporting the grid. This could include direct payments for allowing their heat pump to be used for voltage management, reduced network charges, and faster connections for large-scale heat pumps, especially for social housing providers.

HeatNet is supported by the Strategic Innovation Fund, an Ofgem programme managed in partnership with Innovate UK, and is in its ‘alpha’ or proof-of-concept phase. The project’s initial scoping phase explored the viability of the new tool as well as the methods used in different situations.

Luca Grella, head of Innovation at UK Power Networks said: “The HeatNet project is all about using technology to solve complex challenges. Our goal is to develop a solution that maximises the capacity of existing networks and makes the integration of heat pumps smoother and more efficient.

“We’re also committed to ensuring that households won’t notice any disruptions to their heating, as everything will be fully automated. Ultimately, we aim not be a blocker to the energy transition and to support more homes in connecting heat pumps quickly and easily.”

Matt Osborn, solutions manager at Passv and HeatNet Lead said: “We are excited to be partnering with UK Power Networks on the HeatNet project. This collaboration brings together our expertise in heat pump optimisation for a smarter, more efficient energy grid.

“By harnessing the power of AI and machine learning, HeatNet offers an exciting opportunity to reduce carbon emissions, optimise energy usage and support the UK’s transition to a low-carbon future.”

The Urgent Need for Sustainable Energy Solutions in Schools and Public Spaces

Alex Green

Alex Green, Head of Ashden’s Let’s Go Zero school’s campaign

The UK’s public spaces – from schools and hospitals to libraries and leisure centres – sit at the heart of our communities. They provide essential services, shape local identity, and serve as hubs of learning and wellbeing. Yet, across the country, these spaces face mounting financial and environmental pressures due to rising energy costs and the urgent need to decarbonise.

That’s why the government’s recent announcement of an £80 million investment in rooftop solar panels for 200 schools, alongside £100 million for NHS sites and enhanced support for community energy projects, is a significant step in the right direction. Through Ashden’s Let’s Go Zero campaign, which supports over 5,600 schools on their journey to becoming zero carbon, we’ve seen firsthand the benefits of clean energy initiatives. The reality is simple: solar on schools works. It cuts energy bills, empowers students, and strengthens the resilience of our public services. But we need to scale up and embed long-term policy support to truly unlock the full potential of sustainable energy solutions in schools and beyond.

Schools at the Forefront of Clean Energy Solutions

Schools are uniquely positioned to lead the transition to sustainable energy. They have large, often underutilised roof spaces ideal for solar installations and are embedded in their communities, making them natural partners for local energy initiatives. When schools generate their own energy, they not only reduce their bills but also reinvest those savings into frontline education, tackling the ongoing funding crisis in education.

We’ve already seen local success stories demonstrating the power of community-led solutions. The Leicestershire Solar Schools project, in partnership with Green Fox Community Energy and Leicestershire County Council, is installing free community-funded solar panels on schools, helping them slash electricity costs and reduce their carbon footprint. Similarly, Bath & West Community Energy has installed solar panels on numerous schools, ensuring they benefit from long-term energy savings while contributing to regional decarbonisation efforts.

These examples show what’s possible when schools receive the right support and funding. But too many schools are left relying on their own fundraising or navigating complex financial mechanisms to make sustainable energy projects happen. That’s why greater government backing – through stable, long-term investment and clear policy frameworks – is essential to making this the norm, not the exception.

The Role of Community Energy in Public Spaces

The renewed government support for community energy is another positive development. Community energy projects, where local people own and benefit from renewable energy schemes, create local wealth, build resilience to energy price fluctuations, and fund social initiatives. Low Carbon Hub in Oxfordshire, Repowering London, and Energise Barnsley are just a few examples of organisations successfully tackling fuel poverty and reinvesting energy revenues into their communities.

These initiatives have a vital role to play in schools. Community energy organisations often collaborate with schools, providing not just renewable energy but also education and engagement opportunities that inspire young people to take action on climate change. If we want to create a generation that understands and values sustainability, there’s no better way than making schools living examples of the clean energy transition.

Moving Beyond Start-Stop Policy to Lasting Change

While these recent funding commitments are welcome, they must mark the beginning of a sustained commitment to local and community energy. The UK government’s Local Power Plan aims to deliver 8GW of community and local power – a hugely ambitious and necessary target. But for that to happen, we need long-term certainty. The cycle of start-stop policies in energy investment undermines confidence and slows progress. Instead, we need stable, long-term funding mechanisms that prioritise low-income communities, alongside regulatory reforms that make it easier for schools and public spaces to engage in renewable energy projects.

Public support for this transition is clear. A recent survey found that 82% of people agree that communities should own and benefit from local energy. If we align government policy with this public enthusiasm, we can unlock a once-in-a-generation opportunity to transform our public spaces into clean energy leaders.

Embedding Behaviour Change Alongside Renewable Investment

Finally, it’s important to recognise that infrastructure alone is not enough. Embedding behaviour change within schools and public buildings is key to maximising energy savings and ensuring long-term sustainability. At Let’s Go Zero, we’ve seen how engaging students and staff in energy-saving habits – from monitoring electricity usage to running eco-clubs – creates a culture of sustainability that extends beyond the classroom.

When public spaces lead by example, they influence wider community action. Schools that adopt solar power and energy-saving measures not only cut their own emissions but also inspire families and local businesses to follow suit. This ripple effect is crucial for reaching the UK’s net zero goals.

A Call for Urgent Action

We cannot afford to delay action on sustainable energy in schools and public spaces. Rising energy costs continue to squeeze budgets, and the climate crisis demands immediate action. The government’s recent commitments are a strong starting point, but they must be followed by long-term policies that provide schools, local authorities, and communities with the resources and support they need.

By investing in clean energy for public spaces, we not only reduce emissions but also create resilient, future-ready schools and communities. Let’s seize this opportunity to empower schools, unlock community energy’s potential, and ensure that public spaces remain beacons of sustainability for generations to come.

Why turning lights off can keep them on…

Shifting alliances, wars and inflation are just a few of the forces that threaten supplies of affordable energy. The Pirbright Institute, a research facility that excels in protecting livestock and livelihoods, is no stranger to the fortunes of the power markets. Here, Dave Gillies, Energy Manager, explains how his team’s work helps the Institute weather the global turmoil.

The Pirbright Institute relies on energy. After wages, power is our largest expenditure. The amount needed to keep the laboratory-intensive work of a scientific research facility on track makes us acutely aware of our environmental impact, and the need to cut energy use across our campus.

Recent geopolitical events have led to seismic shifts in energy tariffs. As prices rise, so does operational expenditure. Whilst our funding is agreed every five years by the Biotechnology & Biological Sciences Research Council (BBSRC), and despite forecasts each month through the Crown Commercial Service, sudden utility costs cannot be predicted, but energy bills must be paid. 

Every business has a moral obligation to use energy responsibly, which cuts operational expenditure and mitigates carbon and greenhouse gas emissions. At Pirbright, we focus on a combination of capital development projects, process changes and staff-led innovations to identify and implement change, generate our own power or increase efficiency. In a virtuous cycle, these ethical adjustments make us a more attractive destination for investment.  

Pirbright’s research grant funding sources are increasingly seeking assurance that we undertake our science in an environmentally sustainable way. Yet energy saving measures need not cost the earth, or demand upheaval. The gradual implementation of change with minimal or staggered investment is possible, through measures including:

  • appropriate & effective asset care programmes
  • condition monitoring techniques to detect inefficient equipment for proactive replacement
  • replacing defective equipment with energy efficient units/components
  • using lifecycle & obsolescence registers to forecast replacement expenditure
  • investigating investment in new infrastructure, plant and installations
  • strategic procurement.

When investment opportunities arise, having a selection of solutions to hand can ensure timely implementation. Savings can begin to be realised with minimal delay, so we aim to have such opportunities reviewed and approved by our Senior Leadership Board to progress immediately when funding becomes available. 

BBSRC’s decision to award Pirbright £2.7m in 2022 to install a Combined Heat & Power (CHP) plant has been a resounding success story. With optimum performance, the installation has the potential to save the Institute £1m every year.  Savings will be enhanced when we deploy the next phase of the project: recovering waste heat for low temperature hot water supplies in nearby facilities. Benefits will be enhanced further through an application to export excess energy produced by the CHP to the National Grid, allowing us to generate revenue.

The completion in 2025 of projects currently in progress will save the Institute an estimated 761,486kWh (electricity), worth around £200,000.

In the year ahead, our energy reduction projects include the roll out of low temperature hot water (LTHW) heat recovery across our Plowright building, together with improved ventilation regimes – the latter representing an estimated annual energy saving of c.350,000 kWh. Sitewide lighting optimisation will save c.65,000 kWh per year, whilst adjustment of building temperature setpoints to reduce heating/cooling will save around 346,486 kWh.

Opportunities to rationalise steam and compressed air generation and distribution, and the expansion of our existing solar panel arrays on site, are also being explored. However, physical changes take time, and require significant investment with agreeable payback terms. That’s why ‘quick wins,’ changing processes and proposals with minimal investment costs, are always worth pursuing.

Operating under the principle that the cheapest form of energy is energy you don’t use, some of our older buildings have been decommissioned and research relocated to alternative, upgraded facilities on our Surrey site.

Finally, let’s consider a few office items in use every day, assuming 24hr operation:

  • a single 60W lightbulb costs £115 p.a. and emits 107kg carbon.
  • a desktop PC with 2 Monitors costs £467 p.a. and emits 438kg carbon
  • a laptop with 2 monitors costs £210 p.a. and emits 196kg carbon

The items above total £792 & emit 741kg carbon, so turning off unused equipment makes sense for our finances and the planet. Only using these items during average working hours can save £610 p.a. (570kg carbon).

Switching off unused equipment is something we all do at home, but not always at work. By turning things off, we can help keep them on.
