EDF, Trinasolar sign long-term UK battery opimisation deals
The agreements cover two battery projects: the Ruby BESS project near Aberdeen, a 40MW / 80MWh facility scheduled to become operational in October 2026 and the Chatterley BESS project in Gloucestershire, a 49.9MW / 99.8MWh asset expected to reach commercial operation in March 2027.
Energy supplier EDF has signed two battery optimisation agreements with Trinasolar International Solution Business Unit (ISBU), covering a portfolio of new grid-scale battery energy storage projects located in England and Scotland.
Under the agreements, EDF will use its advanced Powershift platform to manage the assets. This digital trading and optimisation system will provide long-term revenue certainty for Trinasolar ISBU while enabling the projects to deliver essential flexibility services to the UK electricity system, EDF said in a press release.

“As renewable generation and electrification continue to grow, flexible assets such as battery storage are becoming increasingly important to maintaining system stability,” Stuart Fenner, Commercial Director of Business & Wholesale Services at EDF, said. “We’re pleased to be working with Trinasolar ISBU to optimise both projects and help unlock the flexibility needed to support Britain’s transition to a low-carbon, electrified energy system.”
“Following our acquisition of the Ruby and Chatterley projects, we are proud to be partnering with EDF as an important next step in maximising their long‑term value,” Leonardo Lotti at Trinasolar ISBU, said. “Through this collaboration, we can invest with confidence while ensuring the projects are operated effectively to deliver strong commercial outcomes and meaningful benefits for the wider energy system.”
