Envision Energy Expands Into France with Major Energy Storage Project for Kallista Energy

Envision Energy Ventures into the French Energy Storage Market

Envision Energy, a global pioneer in green technologies for wind turbines and energy storage, has made a significant stride into the French market by securing a contract to deliver a comprehensive energy storage project for Kallista Energy. This project, which involves the setup of a remarkable 120 MW / 240 MWh lithium iron phosphate (LFP) battery energy storage system, represents a bold step as the company expands its footprint across Europe.

Located in Saleux, within the Hauts-de-France region, this facility aims to enhance grid stability by providing much-needed ancillary services to the French transmission system operator RTE. The project stands out not only for its scale but also for its significance as Envision's inaugural independent battery storage contract in France. Following the anticipated construction start in June 2025, Envision will also engage in a long-term maintenance agreement lasting at least 14 years, ensuring sustained support and presence in the region, extending well beyond the construction phase.

A vital component of this energy storage system will be the LFP battery cells supplied by AESC, a leading battery technology firm based in Japan, which has established a cutting-edge 10 GWh Gigafactory in Douai, Hauts-de-France, that commenced operations in June 2025. The employment of advanced charging technology demonstrates the commitment of both Envision and Kallista Energy to facilitate the integration of renewable energy into the electrical grid.

Henry Peng, Senior Vice President of Envision Energy, emphasized the importance of France in their strategic expansion, expressing pride in the custom seamless energy storage solution tailored specifically for the Saleux project.

“With our advanced technology and 14-year service agreement, this project reinforces our commitment to grid stability and accelerating the transition towards renewable energy,” stated Peng.

Frédéric Roche, President of Kallista Energy Group, echoed this sentiment, highlighting the critical role this project plays in enhancing the energy ecosystem and the necessity of addressing the common misconceptions surrounding energy storage.

“With the Saleux project, we add another crucial component to the energy ecosystem, facilitating the integration of more renewable energy while maintaining reliability,” said Roche.

As Europe experiences a rapid expansion in energy storage solutions, Envision Energy is at the forefront, leveraging innovative Battery Energy Storage Systems (BESS) to propel the integration of renewable energies into the grid. Envision’s systems showcase vital functionalities such as grid formation, black-start capabilities, and support services that bolster grid stability and optimize electricity distribution. The emphasis on proven designs, safety, and long-term reliability underscores the dedication to facilitating a flexible, resilient, and Net-Zero energy future.

The Saleux project represents not just a business opportunity for Envision Energy but a significant move toward a sustainable future that harmonizes the need for energy reliability with the urgency of renewable energy adoption. By strategically expanding its operations and delivering advanced technology solutions, Envision is reinforcing its position as a leader in the global energy landscape.

In addition to the immediate impact of the Saleux project, Envision Energy's overarching strategy aims to redefine traditional energy practices, paving the way for a renewable-focused ecosystem that emphasizes sustainability and technological innovation. Through strategic partnerships and cutting-edge solutions, Envision Energy is committed to transforming the energy market landscape across Europe and beyond.
