TotalEnergies has launched the largest battery-based energy storage facility in France. Located at the Flandres center in Dunkirk, this site, which responds to the need for grid stabilization, has a power capacity of 61 MW and a total storage capacity of 61 megawatt hours (MWh). It is made up of 27 containers of 2.5 MWh, designed and assembled by Saft, TotalEnergies’ battery affiliate which notably develops advanced batteries for industry.
This project was selected as part of the long-term tender launched by the French Electricity Transmission Network (RTE) in February 2020, where TotalEnergies was awarded battery storage capacities in France. The full commissioning of the site follows the start-up of a first 25 MW unit in January 2021.
A strong and proven industrial track record
The commissioning of this site marks a new step in the development of TotalEnergies’ battery energy storage capabilities. With this project, TotalEnergies is contributing to:
- ensuring sufficient electricity supply in the national grid, especially during peak winter periods,
- guaranteeing grid security by providing fast reserve services*,
- supporting the production of renewable energy by allowing more green electricity to be integrated into the grid.
“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“, said Vincent Stoquart, Senior Vice President Renewables at TotalEnergies. “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“.
“The full commissioning of the Dunkirk site confirms Saft’s experience in terms of lithium-ion (Li-Ion) technology and demonstrates our ability to integrate and deliver large-scale, modular battery storage solutions”, said Hervé Amossé, Executive Vice President, Saft Energy Storage Solutions division. “Fully assembled and tested in Saft’s factories, Intensium Max High Energy containers are standardized and ready to install.” These solutions have a strong track record, with more than 100 operational projects worldwide, allowing customers to take better advantage of renewable energy and to secure electricity supply, from large scale grids to the most remote locations.
*Fast reserve provides rapid delivery to offset an imbalance in the nominal frequency of 50Hz. Activation is automatic, within 15 to 30 seconds.
TotalEnergies and renewable electricity
As part of its ambition to get to net zero by 2050, TotalEnergies is building a portfolio of activities in renewables and electricity. At the end of 2021, TotalEnergies’ gross renewable electricity generation capacity is more than 10 GW. TotalEnergies will continue to expand this business to reach 35 GW of gross production capacity from renewable sources and storage by 2025, and then 100 GW by 2030 with the objective of being among the world’s top 5 producers of electricity from wind and solar energy.
