Institutional investor EIG has announced the launch of Fidra Energy, headquartered in Edinburgh, which aims to establish a 10GW platform of batteries across the UK and other European markets by 2030.
The company is developing three of the largest battery sites in the UK: Thorpe Marsh, a 1.45GW site in South Yorkshire; Bicker Fen 1&2, a 1.2GW site in the East Midlands; and West Burton C, a 500MW site in Nottinghamshire. The company has been formed following the sale of the West Burton Energy operational business to TotalEnergies.
The company says that Thorpe Marsh will be ten times larger than the UK’s largest operational battery; it will be the largest battery in Europe and one of the largest globally. Construction is targeted to begin in 2025.

Chris Elder, Fidra Energy’s Chief Executive Officer, said: “Our strategy is focused on delivering big batteries to major markets through the development of large transmission-connected projects that secure economies of scale. By leveraging our team’s extensive experience in developing, building and operating large power projects, we are well positioned to capture this significant market opportunity.”
