France Boosts BESS Ambitions: Policy Updates, 2 GW Capacity, and Record Tesla Project
France is rapidly accelerating its battery energy storage system (BESS) deployment through a combination of progressive policy updates, massive corporate commitments, and the inauguration of record-breaking facilities. These developments are crucial for integrating the country's growing share of renewable energy.
Policy Shifts and Corporate Commitments
In a significant policy move, the French government confirmed a derogation by the end of 2026 allowing solar PV installations coupled with batteries to reach an installed capacity of up to 25 MW, up from the previous 17 MW limit. This applies provided that the grid injection is capped at 17 MW, a measure designed to facilitate smoother grid connections for hybrid renewable projects.
Corporate targets further underscore this momentum. By 2030, Neoen plans to deploy 1 GW of flexibility capacity, while NW Group has committed €1 billion to add 1.5 GW of electrical flexibility to its platform. Additionally, Gimelec aims to mobilize 6 GW of flexibility in the tertiary sector.
Reaching 2 GW and the 240 MW Tesla Milestone
France's total battery storage capacity has grown exponentially from approximately 316 MW in 2021 to 2 GW by mid-2026. The Transmission System Operator RTE reported 14 GW of battery projects with contracted grid access by the end of 2025, with industry targets aiming for 10 GW by 2030 and 15 GW by 2035.
Highlighting this growth, TagEnergy and Banque des Territoires recently inaugurated France's largest battery storage system in Cernay-lès-Reims. The 240 MW/480 MWh facility utilizes 140 Tesla Megapacks, connecting to the RTE grid at 225 kV to provide essential frequency and voltage regulation.
With Neoen also developing a massive 248 MW/496 MWh project in Seine-et-Marne for 2028, France is firmly establishing itself as a premier market for utility-scale BESS in the European Union, ensuring long-term grid stability and decarbonization.
