- Harmony Energy to install the first large scale 2-hour duration battery in France using Tesla Megapack technology
- The 100 MW / 200 MWh battery storage unit will store the electricity equivalent to the average needs of 170,000 homes for two hours
- Construction of the project is set to begin shortly and the system is expected to be fully operational in winter 2025
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. The project will mark a significant milestone for the French energy system, being France’s first large-scale 2-hour battery.
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, the 100 MW / 200 MWh large-scale renewable energy infrastructure will utilise Tesla Megapack and Autobidder technology and will 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.
Harmony Energy CEO for France Andy Symonds said: “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. We are excited to commence building works on our first project.”
Harmony Energy COO for France Clément Girard said: “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.”
Having developed and energised the three biggest BESS in Europe by MWh – all with Tesla Megapack and Autobidder technology – Harmony Energy projects are designed to protect nature, enhance energy security and support the local community, through setting new standards with biodiversity initiatives, community funds, and cutting-edge technology.
