Fidra Energy has bolstered its battery energy storage system (BESS) development portfolio by acquiring the 1 GW Enderby battery storage project from Innova, pushing its total BESS development pipeline beyond 4.1 GW.

Headquartered in Edinburgh, Fidra Energy purchased the in-development Enderby BESS project prior to its final investment decision (FID), which is scheduled for 2027. The project obtained planning consent in May 2025 and is a key large-scale candidate for the UK government’s new long-duration energy storage (LDES) cap-and-floor offtake scheme. Fidra Energy will receive the outcome of the UK’s inaugural LDES cap-and-floor application round for the Enderby project in summer 2026. A successful scheme award will deliver government-backed, bankable long-term revenue for the project, a critical requirement for investor confidence in under-development energy assets.

Once fully developed, the Enderby BESS will feature a power capacity of up to 1,025 MW, establishing it as one of the UK’s largest battery storage facilities. Fidra Energy boasts a strong track record of securing institutional investment, with backing from global energy investor EIG and the UK’s state-owned National Wealth Fund, laying a solid financial foundation for the project’s delivery.

Morris Van Looy, Chief Growth and Strategy Officer at Fidra Energy, stated that the acquisition marks a significant corporate milestone, underscoring the company’s commitment to accelerating the deployment of large-scale energy storage to support the UK’s 2030 decarbonization goals.

Launched in December 2024, the UK government’s Clean Power 2030 Action Plan sets ambitious targets for grid decarbonization, targeting 23–27 GW of battery capacity and 4–8 GW of long-duration energy storage by 2030 alongside the advancement of flexible energy technologies. Industry data from Modo Energy shows Great Britain had around 6.8 GW of operational BESS capacity by the end of 2025.
