UK-based Harmony Energy has announced that it will commence construction on the Cheviré battery project, France''s largest battery energy storage system (BESS).
The project will be built in the commune of Cernay-lès-Reims, in the department of Marnes, and is around five times bigger than the largest system online in France today, TagEnergy said.
Les BESS connaissent une croissance exponentielle. En France, les capacités de stockage raccordées au réseau de distribution d''électricité ont été multipliées par 11 en quatre
According to the European Commission, France currently has 400 megawatt (MW) of grid-scale BESS capacity installed, with another 760MW in the pipeline – 360MW of which

The 240MW/480MWh battery energy storage system (BESS) will be in the commune of Cernay-lès-Reims, in the Marne department in the northeast of France.
The project will be located in Nantes Saint-Nazaire Harbour, on a site previously occupied by the Cheviré power station, which was operational from 1954 to 1986 and fuelled by coal, gas and oil.

France is scaling up to meet rising electricity demand, but grid constraints threaten to hinder progress. Learn how battery storage could unlock their clean energy future.

Other large-scale BESS projects in France have also progressed recently. Late last month, Switzerland-based IPP Alpiq acquired a BESS project from UK-based developer Harmony Energy Oise, north of Paris, while Harmony Energy announced it would build a separate project near Nantes in July – both sized at 100MW/200MWh.

UK-based Harmony Energy has announced that it will commence construction on the Cheviré battery project, France’s largest battery energy storage system (BESS).
The largest operational BESS in France that Energy-Storage.news has reported on is a 61MW/61MWh project owned by oil and gas major TotalEnergies, deployed by its system integrator subsidiary Saft. IPP TagEnergy will soon start construction on the largest BESS project in France, at 240MW/480MWh, with Tesla providing BESS and EPC services.
Compared to other major European economies, France has a relatively smaller grid-scale BESS pipeline forecasted to come online over the course of this decade, at least according to research firm LCP Delta.

Developers Acacia, Green Tower and Eren Industries have partnered to develop and build 500MW of standalone BESS in France.
The BESS system will power 170,000 homes for two hours – supplying a population larger than that of the city of Nantes.
