The news was released by Bloomberg this morning. Leading battery storage developer Harmony Energy is set to deliver France’s largest battery energy storage system (BESS)—the Cheviré battery project – using Tesla Megapack technology.
Tesla (TSLA) has secured a massive new Megapack order that will power France’s new largest energy storage system. TagEnergy announced today that it started construction on a new energy storage project in Marne, which should become France’s largest battery project. They confirmed that they will use Tesla Megapacks:
Lisbon-headquartered renewable energy company TagEnergy has launched construction of France’s biggest battery energy storage system (BESS). Tesla will contribute to the project also, offering market access services and its expertise in advanced storage solutions.
TagEnergy announced today that it started construction on a new energy storage project in Marne, which should become France’s largest battery project. They confirmed that they will use Tesla Megapacks: This landmark project marks the start of an ambitious expansion plan for 2025, with accelerated solar and storage development activities.
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.
“TagEnergy is proud to announce this flagship project in France, just weeks after connecting the first phase of the Southern Hemisphere’s largest wind farm in Australia and the UK’s largest transmission-connected battery”, said Franck Woitiez, CEO of TagEnergy.
