Envision Energy, a world leader in green technology for wind turbines, energy storage, and green hydrogen solutions, announced that it has signed an EPC (engineering, procurement, and construction) contract to supply Kallista Energy, a European renewable energy producer, with a 120 MW/240 MWh Lithium Iron Phosphate (LFP) battery energy storage project in Saleux, which is in the Hauts-de-France region of France.
The Saleux plant will supply frequency control services to the power grid on the reserve markets of the French transmission system operator RTE using Envision Energy’s direct current (DC), alternating current (AC), and power conversion systems (PCS). After previous triumphs in Europe, this project represents Envision Energy’s first independent battery energy storage contract in France. Envision Energy will provide a minimum of a 14-year long-term maintenance (LTSA) agreement, starting construction in June 2025, ensuring ongoing presence in the area once the construction phase is complete.
The LFP battery cells, a crucial part of the BESS project, will be provided by AESC, a well-known battery technology business with its headquarters located in Japan. AESC has been producing since June 2025 in its state-of-the-art 10 GWh Gigafactory, which is situated in Douai, Hauts-de-France.
Henry Peng, Senior Vice President and President of Latin America and European Region, Envision Energy, stated: “France is a key market for Envision Energy as we expand our presence across Europe, and our partnership with Kallista Energy marks a significant milestone in this journey. We are proud to deliver a fully integrated, turnkey energy storage solution tailored to the Saleux project. Backed by our advanced technology, EPC expertise, and a 14 year long-term service agreement, this project demonstrates our deep commitment to supporting grid stability and accelerating the transition to renewables with safe, reliable, and scalable energy solutions.”
Frédéric Roche, President of Kallista Energy Group, stated, “With the Saleux project, Kallista Energy adds another building block to the energy ecosystem needed to facilitate the integration of more renewable energy into the grid while ensuring its reliability. We must move beyond the misconception that electricity cannot be stored, in order to accelerate the deployment of renewables and the shift away from fossil fuels. Our group is working on other projects like Saleux to keep up the momentum.”
