Voltalia has commissioned the 32MW/32 megawatt-hour Hallen battery energy storage scheme near Bristol in south-west England.
Hallen is a lithium-ion battery storage facility comprising 16 modules, each with a capacity of 2MWh per unit.
The plant stored and then released its first kilowatt-hours on 23 December, having initially beenscheduled for the first quarter of 2022.
It will operate in several markets providing frequency management, balancing and other ancillary services on the UK grid, locally and nationally.
Voltalia chief executive Sebastien Clerc said: “The commencement of commissioning of the Hallen Battery Energy Storage Scheme is another success for Voltalia in this rapidly developing segment.
“We are very happy to support the energy transition in the UK, which is experiencing strong growth in renewable energies in its energy mix.”
