Energy company TotalEnergies announced today the launch of the largest battery-based energy storage facility in France, aiming to help respond to the need for grid stabilization, and to support the production of renewable energy by allowing more green electricity to be integrated into the grid.

The new facility is located at the Flandres center in Dunkirk and has a power capacity of 61 MW and a total storage capacity of 61 MWh. It is made up of 27 containers of 2.5 MWh and designed and assembled by TotalEnergies’ battery affiliate, Saft. The full commissioning of the site follows the start-up of the first 25 MW unit in January 2021.

Energy storage solutions form one of the key building blocks for the rapidly expanding clean energy transition, given the intermittent generating nature of many sources of renewable energy, such as wind and solar, and the need to satisfy round-the-clock energy demand, while ensuring that energy is not wasted. According to TotalEnergies, with the new project, the company is contributing to ensuring sufficient electricity supply in the national grid, especially during peak winter periods, and guaranteeing grid security by providing reserve services.

Vincent Stoquart, Senior Vice President Renewables at TotalEnergies, said:

“We are proud of the commissioning of the largest storage site in France and to be able to support RTE, the grid operator, in guaranteeing the stability of the grid and thus enabling the increased development of renewable energies. With the success of this project and Saft’s expertise in batteries for energy storage, TotalEnergies intends to deploy its storage solutions in countries where the Company is actively developing renewable energies.”
