Ameresco entered into a $249M contract and Long-Term Service agreement with Atlantic Green for one of the UK’s largest Battery Energy Storage Projects

Ameresco, Inc., a leading cleantech integrator specializing in energy efficiency and renewable energy, today announced that Ameresco and Envision Energy have been chosen by Atlantic Green to build the Cellarhead project, a 300-megawatt (MW) battery energy storage project (BESS) with a maximum energy capacity of 624 megawatt hours (MWh). The Cellarhead BESS project will be connected to National Grid’s Cellarhead sub-station and will provide the UK with additional energy security and reliability.

Construction is anticipated to commence on site this year with connection to the electricity grid anticipated at the end of 2026. With a maximum energy capacity of 624 megawatt hours, the Cellarhead BESS project will support the UK’s ambition to achieve net zero, supporting the increased penetration of clean energy generation, decrease reliance on fossil fueled generation, and ultimately mitigate greenhouse gas (GHG) emissions.
