Harmony Energy has announced plans to build France’s largest battery energy storage system – the 100MW /200MWh Cheviré battery project – which the developer said will be the country’s first large-scale two-hour battery.
Located in Nantes Saint-Nazaire Harbour, on a site previously occupied by the Cheviré power station, the battery will utilise Tesla Megapack and Autobidder technology and provide enough electricity to power an estimated 170,000 homes for two hours – greater than the population of the City of Nantes.
The project will provide critical balancing services to the French electricity grid network and enable the replacement of fossil fuels with renewable energy, said the developer.
“Developing and operating vital battery energy storage facilities across France, will lead to enhanced energy security, more affordable energy bills, and the decarbonisation of the grid,” said Harmony Energy chief executive for France Andy Symonds.“We are excited to commence building works on our first project.”
Harmony Energy chief operating officer for France Clément Girard added: “It’s an exciting location given the historical importance of the fossil-fuel coal power station, but looking ahead, the delivery of the Cheviré BESS will transform the site into exactly the opposite, facilitating the green electrification of the French energy system, whilst offsetting several hundred thousand tons of CO2.”
