Developer-operator Atlantic Green has enlisted system integrator Ameresco and clean energy manufacturer Envision Energy for a 300MW/624MWh BESS project in the UK.

The Cellarhead battery energy storage system (BESS) project will be connected to National Grid’s Cellarhead substation in the West Midlands and have a maximum energy capacity of 624MWh. Construction is expected to begin this year, with final connection to the grid slated for the end of 2026.

The deal between the parties is worth £196.5 million (US$250 million). Ameresco will build the project via an engineering, procurement and construction (EPC) and operation & maintenance (O&M) agreement while Envision Energy will supply the BESS units.

“We’re excited to announce our collaboration with Atlantic Green to construct one of the largest battery energy storage projects in the UK,” said Mark Apsey, senior vice president of UK Operations at Ameresco.
