SSE Renewables has announced the principal contractor and system supplier for its battery-based energy storage project at Fiddler?s Ferry, Warrington. Fluence has been selected as the supplier of the battery-based energy storage system to SSE. The project will utilize the Gridstack platform, proven for its industry leading safety and reliability.

Fluence has delivered or contracted more than 8.7 GW of energy storage globally, including over 2 GWh in the UK and Irish markets, making it a highly experienced and trusted partner for SSE Renewables to deliver the Fiddler?s Ferry project. Construction is set to begin at the site in the coming weeks after SSE Renewables took a final investment decision in December 2023. OCU Energy will be the principal contractor at Fiddler?s Ferry.

The 150 MW /300 MWh battery storage project is situated at the site of the former SSE-owned coal-fired power station at Fiddler?s Ferry. The power station was decommissioned in March 2020, and the final demolition of its cooling towers came at the end of last year. Once operational, the system will be capable of storing power for release back to the UK National Grid when it is needed the most ?

helping to manage peaks of energy demand. This flexibility helps balance energy supply and demand more effectively and maximise the potential of available renewable technology to power the grid ? even when the sun is not shining, or the wind is not blowing.
