Global systems integrator Fluence will supply batteries for a 150MW/300MWh battery storage project being developed by SSE Renewables at Fiddler’s Ferry, Warrington, UK.

The 2-hour duration project will use Fluence’s Gridstack platform, the company’s modular battery energy storage system (BESS) solution, which is being used in multiple international storage developments such as an Australian 300MW grid-forming project, as covered by Energy-Storage.news.

SSE Renewables selected Fluence to supply the BESS, and contracted Stockport-based OCU Energy as principal contractor at Fiddler’s Ferry.

The battery storage project is situated at the former SSE-owned coal-fired power station at Fiddler’s Ferry in northwest England. The power station was decommissioned in March 2020 and the final demolition of its cooling towers occurred at the end of last year.

Construction on the project will begin at the site in the coming weeks after SSE Renewables made a final investment decision in December 2023.

Brian Perusse, managing director of Fluence Energy UK, said: “Fluence is committed to delivering safe and reliable energy storage systems that advance the energy transition and we are proud to work with SSE Renewables on this highly significant project.

“Fluence has a track record of operating systems with high performance levels and we are committed to doing the same for Fiddler’s Ferry.”
