EDF and Elements Green agree long-term deal to support 360MW Staythorpe battery project
- Staythorpe BESS will be one of the UK’s largest when it begins operation in 2027
- EDF will provide a guaranteed minimum income and optimise the asset through its Powershift platform
- The project will deliver local jobs, biodiversity improvements and greater flexibility for renewable energy
EDF has signed a long-term arrangement with solar and energy storage developer Elements Green to support delivery of the 360MW/720MWh Staythorpe Battery Energy Storage System (BESS), now under early-stage construction in Nottinghamshire.
Scheduled to be operational in 2027, Staythorpe will be one of the largest battery storage projects in the UK, providing critical flexibility to balance supply and demand, and enabling the integration of more renewable power into the grid. When operational, it will have the capacity to power over 95,000 homes for a full day.
Under the agreement, EDF’s Wholesale Market Services team will guarantee a minimum level of income from grid balancing, alongside the project’s 15-year capacity market contract.
This gives the project greater financial certainty and supports investment in the infrastructure needed for Britain’s shift to a low-carbon energy system. The EDF team will also operate the battery through EDF’s Powershift platform, making sure it earns the best possible return from available market opportunities.
Elements Green recently reached financial close on a £140 million unitranche debt facility, provided by Goldman Sachs Alternatives, for the Staythorpe BESS. This milestone paves the way for full construction and energisation of the site, which will strengthen the UK’s energy system, deliver biodiversity enhancements, support community initiatives, and create skilled local employment.
Stuart Fenner, Commercial Director at Wholesale Market Services at EDF, said: “Staythorpe isn’t just another project. It is a major step in building the reliable, secure, low carbon power system Britain needs. Large-scale storage is essential to make the most of renewable energy, and with Elements Green we are giving this project the certainty and capability to deliver lasting value and real progress towards net zero.”
James Gates, CIO at Elements Green, added: “Staythorpe is exactly the kind of large-scale project that can make a meaningful impact on the UK’s energy system. Its location next to a major National Grid substation makes it ideally suited for better storage at scale, and partnering with EDF ensures we have the commercial framework in place to deliver reliable performance for decades to come”.
EDF is the UK’s biggest generator of low carbon electricity and a leading provider of battery optimisation and trading services. With over 950MW of battery storage now under contract in Great Britain, the company continues to work with developers, investors and the grid to build a more flexible, resilient, and low carbon energy system.
About EDF
EDF is driving the transition towards An Electric Britain – a secure, affordable, low-carbon future for everyone. As Britain’s biggest generator of zero carbon electricity, we are investing more than £100 million weekly in Britain’s electricity infrastructure. We supply millions of customers with electricity and help homes and businesses switch to electricity for heating, transport and industrial processes.
We operate five nuclear power stations and more than 35 onshore wind farms and three offshore wind farms. Since 2009, EDF has invested almost £9 billion in the nuclear fleet to improve reliability and extend station lifetimes. The five generating stations currently supply about 12% of the UK’s electricity demand.
EDF is building the UK's nuclear renaissance with the construction of a new nuclear power station at Hinkley Point C. We are a minority investor (12.5%) in and major supplier to a replica plant at Sizewell C in Suffolk. Hinkley Point C and Sizewell C will provide low carbon electricity to meet 14% of UK demand and power around 12 million homes. EDF Group companies Framatome and Arabelle Solutions have a presence in the UK and manufacture critical equipment such as reactor pressure vessels and turbines.
EDF is enabling its 5 million customers, both in business and at home, to choose electric solutions that save cash and carbon, whether it is buying an electric car, generating and storing electricity, selling energy back to the grid or installing solar panels or a heat pump. In 2025, EDF’s Customers business was ranked as one of the Sunday Times’s Best Place to Work.
It is also one of the UK’s leading developers of renewable energy through EDF power solutions UK and Ireland. We have more than 2GW of renewable generation in operation and over 10GW in construction, planning and development across a range of technologies including onshore and offshore wind, solar and battery storage.
We are one of the largest suppliers to British business and a leading supplier of innovative energy solutions that are helping businesses become more energy independent. In addition, the company’s energy services business, Dalkia, one of the UK and Ireland’s largest technical service providers.
