Envision Energy has executed an engineering, procurement, and construction (EPC) agreement. Under the agreement, the company will supply a 120 MW/240 MWh lithium iron phosphate battery energy storage project for Kallista Energy in Saleux, France. Construction of the project will commence in June 2025.
The site will employ Envision Energy’s direct current, alternating current, and power conversion systems to provide the power grid with frequency regulation services on the French transmission system operator RTE’s reserve markets. Furthermore, Envision Energy will supply a minimum of a 14 year long-term maintenance agreement. The lithium iron phosphate battery cells, which are a key component of the project, will be supplied by AESC.
Earlier in June 2025, Envision Energy entered into a strategic partnership with SUN Terra to develop a complete energy storage ecosystem across Southeast Asia, India, and Australia. The partnership aims to accelerate the deployment of energy storage systems technologies and build resilient supply chains.
