Matrix Renewables Entrusts EDF with Optimization of Its 500 MW Scottish BESS

Matrix Renewables has signed a long-term Battery Optimisation Agreement with EDF for a 500 MW/1,000 MWh battery energy storage system (BESS) currently under construction at Eccles, Scotland. EDF will provide route-to-market services and optimize the asset once it becomes operational, according to the two companies. Commercial operations are scheduled to begin in summer 2027. It will be Matrix Renewables' first standalone UK battery project and, according to the company, one of the largest in the country. As the storage market expands rapidly, Recharge Power recently secured an 80 MWh storage order in Japan.

Strategic positioning along key transmission corridors

The Eccles site is located along key transmission corridors between Scotland and England, according to Matrix Renewables. This positioning aims to reinforce the grid and facilitate electricity flows across the national network. By storing surplus generation and releasing it during periods of high demand, the project seeks to support the integration of renewable energy into the UK electricity system. Other players are also advancing in this segment: Corsica Sole is deploying 5 GWh of storage capacity across Europe.

The project aligns with the UK government's Clean Power 2035 and Net Zero 2050 targets. Matrix Renewables indicates that the initiative is part of a broader strategy to expand its battery storage portfolio in the UK. The company aims to contribute to a cleaner, more flexible electricity system. It is backed by TPG's impact investing platform.

EDF deploys its Powershift platform for real-time optimization

EDF will optimize the system via its Powershift platform, which would allow the battery to be adjusted in real time to support grid stability, manage peak demand and facilitate the integration of more low-carbon electricity, according to Stuart Fenner, Commercial Director of Business & Wholesale Services at EDF. The agreement grants EDF the role of commercial operator for the project over its lifetime. Chris Matthews, Chief Commercial Officer at Matrix Renewables, states that battery storage will play a critical role in enabling the growth of renewable energy and the resilience of the electricity grid. This first standalone deployment by Matrix Renewables in the UK marks a milestone in the scale-up of large-scale storage in the country.
