- Matrix Renewables’ 500MW/1GWh battery storage project in Scotland will strengthen the UK electricity system by providing critical flexibility to support grid operations
- Large-scale battery storage will enable greater integration of renewable energy by storing excess power and releasing it during periods of high demand
- Project supports the UK’s transition to a cleaner and more reliable power system, contributing to the Clean Power 2035 ambitions and Net Zero 2050 target
Matrix Renewables, the leading renewable energy company backed by TPG’s impact investing platform, has entered into a long-term Battery Optimisation Agreement with EDF for a 500MW/1GWh battery energy storage system currently under construction at Eccles, Scotland.
Under the agreement, EDF will provide route-to-market services and optimise the battery across UK power markets once the asset becomes operational. Scheduled to begin commercial operations in summer 2027, the project will be Matrix Renewables’ first standalone battery storage development in the UK and one of the largest connected to the British electricity system.
Strategically located along key transmission corridors between Scotland and England, the Eccles battery storage facility will play an important role in strengthening grid resilience and enabling the efficient flow of electricity across the network. Additionally, by storing excess electricity generated from renewable sources and releasing it during periods of high demand, the project will support the integration of more renewable energy into the UK’s electricity system.
The project is part of Matrix Renewables’ broader strategy to expand its battery storage portfolio and support the UK’s transition toward a cleaner and more flexible power system, contributing to the government’s Clean Power 2035 ambitions and Net Zero 2050 target.
Chris Matthews, Chief Commercial Officer at Matrix Renewables, said: 'We are proud to be delivering one of the UK’s largest battery storage projects and to partner with EDF for its commercial optimisation. Battery storage will play a critical role in enabling the continued growth of renewable energy while strengthening the resilience and flexibility of the electricity system.'
Stuart Fenner, Commercial Director of Business & Wholesale Services at EDF, said: 'Delivering EDF’s mission to build an Electric Britain depends on flexible assets that can respond instantly to the needs of the system. This project will provide exactly that capability. Using our Powershift platform, we will optimise the battery in real time to support grid stability, manage peak demand and help integrate more low-carbon generation.'
All planning conditions for the Eccles project have been discharged, and full consent has been secured, allowing construction to progress as planned.
Matrix Renewables continues to actively expand its UK battery storage and generation pipeline and aims to develop more than 3GW of capacity across the country in the coming years.
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.
