What Fidra Energy does

Fidra Energy Ltd. is a UK-based battery energy storage system (BESS) developer and operator headquartered in Edinburgh, established in 2024 as the European BESS platform of EIG (Energy Infrastructure Group) with co-investment from the UK National Wealth Fund. The company develops, builds, and operates large-scale, grid-connected lithium-ion battery storage projects using Sungrow's PowerTitan 2.0 liquid-cooled grid-forming technology, currently managing a UK pipeline exceeding 4.1GW across four projects: Thorpe Marsh (1.45GW/2.9GWh in Yorkshire, the largest BESS project in the UK, under construction since September 2025), West Burton C (500MW/1GWh in Nottinghamshire), Bicker Fen 1&2 (1.2GW/2.4GWh in Lincolnshire), and Enderby (1,025MW in Leicestershire, acquired from Innova in June 2026).

The company's business model is anchored on three revenue streams: (1) 15-year UK Capacity Market awards providing fixed revenues (approximately £357M secured across Thorpe Marsh and West Burton C, representing ~22% of total derated new build BESS capacity in the T-4 auction); (2) long-term tolling agreements with generators such as Drax (10-year deal for 250MW/500MWh at West Burton) providing inflation-indexed fixed fees in exchange for counterparty dispatch rights; and (3) energy trading and balancing services through offtake agreements with EDF, Octopus Energy, and Statkraft covering approximately 80% of Thorpe Marsh capacity. Revenue is therefore a mix of regulated recurring capacity payments, contracted recurring tolling fees, and usage-based trading income.

Fidra raised approximately £445M in equity from EIG and the National Wealth Fund plus £594M in debt from international lenders in September 2025 to reach financial close on Thorpe Marsh, totaling approximately £1B for that project alone. The company is led by an experienced management team previously responsible for West Burton Energy, including CEO Chris Elder, COO Lisa Mackay, CFO Tony Julius, and CGO Morris Van Looy, who led the prior £450M divestiture of West Burton B power station to TotalEnergies. Fidra's stated ambition is to develop 10GW of battery storage in the UK and other European markets by 2030.

Revenue model

1. Capacity Market Revenue: Long-term capacity market awards from the UK Government providing fixed revenues over 15-year contract periods. Fidra secured ~22% of total derated new build BESS capacity in the T-4 Capacity Market Auction for 2028/29, generating approximately £357 million in fixed revenues for Thorpe Marsh and West Burton C projects in today's money.
2. Tolling Agreements: Long-term tolling agreements where counterparties (e.g., Drax) pay fixed annual fees indexed to inflation in exchange for full operational control and dispatch rights. Fidra retains construction, maintenance, and availability risks. Drax signed a 10-year tolling agreement for 250MW/500MWh at West Burton.
3. Energy Trading and Balancing Services: Revenue from providing grid balancing services, storing energy during excess renewable generation periods and releasing during peak demand. Projects have signed long-term offtake agreements covering approximately 80% of Thorpe Marsh capacity with EDF, Octopus Energy, and Statkraft.
