UK battery energy storage system (BESS) owner-operator Gresham House Energy Storage Fund has put a 50MW/50MWh project into commercial operation in Lancashire.

Situated in Penwortham, south-west of the county capital Preston, the 1-hour duration BESS is set to be expanded to 2-hours in the summer, meaning its capacity would be 50MW/100MWh.

With the commencement of this new BESS, the operational capacity of the Gresham House Energy Storage Fund (listed as GRID) has now reached 790MW/926MWh. The project is the fund’s 25th operational asset since IPO.

Ben Guest, fund manager of GRID and managing director of Gresham House New Energy, said: “Penwortham is our 25th operational site acquisition since IPO. We’re pleased to have hit this milestone and to be completing projects at a steady pace with Grendon, West Didsbury, York and now Penwortham all being energised in the last nine months.
