Envision Energy Achieves Major Milestone in the French Energy Storage Market

Envision Energy Enters the French Energy Storage Market

Envision Energy, renowned globally for its advancements in green technology including wind turbines, energy storage, and hydrogen solutions, has marked a significant achievement by entering the French energy storage sector. The company has entered into a contract to deliver a sizable energy storage project for Kallista Energy, a notable player in the European renewable energy landscape.

Details of the Project

The project, situated in Saleux, located in the Hauts-de-France region, encompasses an impressive 120 megawatts (MW) of energy storage capacity, translating to 240 megawatt hours (MWh) of electricity. This significant development will utilize Envision's cutting-edge technology, featuring a combination of direct current (DC) and alternating current (AC) units along with innovative power conversion systems (PCS).

Scheduled to commence construction in June 2025, this initiative marks Envision Energy's inaugural independent battery energy storage contract within France, a country that has become a focal point for their expansion efforts across Europe. As part of the agreement, Envision will implement a long-term maintenance service agreement, spanning a minimum of 14 years, ensuring consistent support even after the completion of the installation.

Partnership with AESC

A key element of the energy storage solution involves the utilization of Lithium Iron Phosphate (LFP) battery cells, which will be provided by AESC, a leading battery technology firm based in Japan. AESC has a modern Gigafactory with a production capacity of 10 GWh, located conveniently in Douai, also in the Hauts-de-France region, which has already been operating since June 2025. This partnership signifies a critical collaboration aimed at enhancing the technology and efficiency of Envision's energy storage solutions.

Supporting Grid Stability

Henry Peng, Senior Vice President and the head of Envision Energy’s operations in Latin America and Europe, shared insights on the importance of this venture. He stated, "France is a pivotal market for us. Our partnership with Kallista Energy not only signifies a crucial milestone in enhancing our European footprint but also showcases our commitment to providing fully integrated energy solutions that bolster grid stability."

The project is set to supply vital frequency regulation services to France's transmission system operator, Réseau de Transport d'Électricité (RTE), thus contributing to the overall stability of the grid. Envision's energy storage technology is designed to support the transition to a more renewable-driven energy model, which is increasingly essential in the current climate.

Kallista Energy's Vision

Frédéric Roche, President of Kallista Energy Group, elaborated on the significance of projects like Saleux in revolutionizing the energy sector. Roche stated, "We aim to dismantle the prevailing notion that electricity cannot be stored. Initiatives such as Saleux are critical in advancing the integration of renewable energy into the grid while maintaining reliability."

The Future of Energy Storage

The demand for energy storage solutions is burgeoning across Europe as the region strives to optimize renewable energy output. Envision Energy, leveraging its considerable technical expertise, is at the forefront of this movement, pushing for the adoption of advanced Battery Energy Storage Solutions (BESS). Their systems are engineered not just for reliability and safety, but to deliver essential services that enhance grid performance and facilitate the smooth incorporation of renewable sources into the energy mix.

As we move towards a future that prioritizes sustainable energy sources, partnerships and technological advancements like those exemplified by the Envision-Kallista collaboration will be essential. The Saleux project is not merely a step forward for Envision Energy, but a vital component of the broader effort to develop a resilient, flexible energy network that ultimately leads to a net-zero future.
