Loudwater BESS

Loudwater BESS is located in Buckinghamshire and is optimised by Statkraft.

‍

Built next to a farm, Loudwater BESS is generating into the National Grid from beautiful High Wycombe.

Project overview

Loudwater is a 40MW / 55MWh Battery Energy Storage System which Eku Energy is delivering near High Wycombe in Buckinghamshire, England. Constructed started in mid 2024.

Since completion in June 2025, Loudwater BESS provides vital flexibility to enable more renewable generation and increase the resilience of the UK electricity network.

To meet net zero by 2050, the UK Government has committed to decarbonise the electricity system by 2035. Battery storage is a critical enabler of this transition, helping to store and shift renewable generation to times of day when it is most needed, while helping to balance electricity supply and demand second-by-second.
