Grenergy has secured capacity contracts for four battery energy storage system (BESS) projects in UK with a combined capacity of 190 MW/760 MWh. The contracts were awarded in the latest auction conducted by NESO, the country’s energy system operator, and will remain in effect for 15 years. The projects include two hybrid projects and two standalone BESS projects, namely Scalm Park, Spring Lane, Buxton Road, and Fibden Farm.
The contracted services are scheduled to commence between October 2029 and October 2030. Under the agreement, the projects will receive fixed remuneration indexed to inflation at a rate of £27.10 per kW per year throughout the contract period. This arrangement ensures a guaranteed minimum revenue exceeding €40 million over the duration of the contracts. Additionally, the projects are expected to generate further income through energy trading activities and participation in other electricity markets, including ancillary service markets.
In February 2026, Grenergy secured a solar supply contract for the Fibden Farm hybrid project. The Fibden project comprises 40 MW, or 53 MWp, of solar capacity with 160 MWh of BESS. It will operate under a 20-year agreement expected to commence between March 2028 and February 2029, guaranteeing minimum revenues of £55 million throughout the contract period. The awarded price for the project is £65.23 per MWh.
