NW Group

Energy transition accessible to all NW is a French energy company specializing in distributed and autonomous battery energy storage systems (BESS). It is the leader in distributed storage in France and Finland. By the end of 2026, the Group operates 2 GW / 4 GWh of battery capacity across 1,600 sites. NW is also a significant player in high-power electric vehicle charging through its IECharge® technology. The company is currently established in eight countries, with the ambition to become a leading European storage operator. At the core of its model is the JBox®, a French technology protected by several patents. Each unit — 1 MW / 2 MWh, connected to the medium-voltage grid and occupying less than 30 m² — provides system services to electricity networks, including frequency regulation, reserve capacity, and peak demand support. It is now regarded as an essential solution in the strategic sector of distributed electricity storage. An integrated group — NW designs, develops, finances, installs, and operates its production, storage, injection, and consumption solutions. Each system functions as a digitalized node interacting within a broader digital and electrical ecosystem. Certified as BSP/BRP in France, Finland, and Sweden, NW operates its own aggregation platform to optimize the value of its assets in electricity markets. An independent group — NW’s economic model enables it to operate without reliance on subsidies. Its technological solutions are sovereign and patented. A pioneer in energy storage, its founder and CEO holds a 70% ownership stake in the company. A committed group — NW contributes to the resilience and flexibility of the power grid, facilitates the integration of low-carbon energy, and supports the transformation of consumption patterns toward widespread electrification. As the first energy transition unicorn in France, NW is recognized with the Solar Impulse and Greentech Innovation labels and is a member of the French Tech Next40.
