France-headquartered renewable power producer Voltalia brought online a 32MW / 32MWh battery energy storage system (BESS) project in southern England in December, the company’s second UK battery project.

The lithium-ion BESS is located at Avonmouth, near Bristol, and consists of 16 modules, each with a capacity of 2MWh per unit.

Construction began in April of last year and it has been commissioned ahead of an expected date during the first quarter of 2022.

“The commencement of commissioning of the Hallen Battery Energy Storage Scheme is another success for Voltalia in this rapidly developing segment,” said Sébastien Clerc, CEO of Voltalia.
