Located at Joux-la-Ville in Bourgogne-Franche-Comté, in the vicinity of Innergex’s Yonne and Yonne II wind farms, Tonnerre is a 9 MW / 9 MWh battery energy storage system. The facility provides grid stability and helps balance and secure the French power transmission system. The energy storage solution has been designed by EVLO, a subsidiary of Hydro-Québec. The IEC 62933- certified and UL9540A-tested battery energy storage system (BESS) enclosure includes several exclusive safety features and uses a unique lithium iron phosphate (LFP) technology, known for its superior thermal and chemical stability. Tonnerre has been awarded a 7-year Contract for Difference offering a fixed-price contract for capacity certificate with the Réseau de Transport d’Électricité (RTE). The facility will generate additional revenues that will vary based on prevailing energy pricing.
Crédit Agricole Assurances owns a 30% interest in the facility since October 26, 2023.
