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 500 MW/1 GWh battery energy storage system (BESS), 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.
