Envision Energy's Landmark Project in France's Energy Storage Landscape

Envision Energy, a powerhouse in green technology innovations, has officially embarked on a significant venture in France's energy market. This latest project involves the engineering, procurement, and construction (EPC) of a cutting-edge Lithium Iron Phosphate (LFP) battery energy storage system, which boasts a capacity of 120 megawatts and 240 megawatt-hours. It is being developed for Kallista Energy, a recognized player in the European renewable energy sector.

Located in Saleux, a town in the Hauts-de-France region, the project is set to play a critical role in stabilizing the local power grid. Scheduled for construction to commence in June 2025, the site will utilize advanced DC (direct current) and AC (alternating current) power systems, along with sophisticated power conversion systems (PCS), to deliver vital frequency regulation services to France's transmission system operator, RTE. This marks a pivotal moment for Envision Energy as it steps into the French market with its first independent battery energy storage contract.

According to Henry Peng, Envision Energy's Senior Vice President, France represents an essential part of the company's ongoing expansion within Europe. He expressed pride in collaborating with Kallista Energy to deliver a fully integrated, turnkey energy storage solution tailored to the specific needs of the Saleux project. This initiative leverages Envision's technological advancements and their EPC expertise, along with a 14-year long-term service agreement that provides essential regional support beyond the construction phase.

Notably, the battery cells fundamental to the project's success will be sourced from AESC, a prominent Japanese battery technology provider. AESC operates a state-of-the-art gigafactory in Douai, also situated in the Hauts-de-France, which began production in June 2025. This strategic partnership underlines the project’s commitment to utilizing the best available technology to ensure high-performance outcomes.

Frédéric Roche, President of Kallista Energy Group, remarked on the significance of the Saleux project as a crucial element in building a resilient energy ecosystem capable of integrating increased renewable energy into the grid while maintaining reliability. He emphasized the necessity of changing the narrative surrounding electricity storage capabilities to further facilitate the transition toward renewable sources and reduce dependence on fossil fuels.

As the demand for energy storage continues to surge across Europe, Envision Energy stands at the forefront, delivering innovative Battery Energy Storage Solutions (BESS) that enhance the integration of renewables into the energy grid. Their systems are equipped with essential features such as grid-forming and black start functionality, which are critical for supporting grid stability and optimizing power distribution. The company prides itself on a robust design philosophy focused on safety, reliability, and long-term efficiency, ensuring their energy storage products can withstand the test of time while supporting the shift to a sustainable, flexible, and net-zero energy future.

In conclusion, the Saleux project epitomizes the collaborative efforts of private companies like Envision Energy and Kallista Energy in pursuing innovative solutions for energy storage. It not only exemplifies the technological advancements in the sector but also highlights the growing commitment to harnessing renewable energy resources for a sustainable future. As construction gets underway, the eyes of the energy community will surely be focused on the developments within Saleux, eager to witness the impact of this pioneering project on France's energy landscape.
