Project Overview
TotalEnergies has launched France's largest battery-based energy storage facility at the Flandres center in Dunkirk. The site has a power capacity of 61 MW and a total storage capacity of 61 MWh, consisting of 27 containers of 2.5 MWh each, designed and assembled by Saft, TotalEnergies’ battery affiliate.
Tender and Commissioning
This project was selected as part of a long-term tender by the French Electricity Transmission Network (RTE) in February 2020. The full commissioning of the site follows the start-up of a first 25 MW unit in January 2021.
Grid Stabilization and Renewable Energy Support
The facility aims to ensure sufficient electricity supply in the national grid, especially during peak winter periods, and to guarantee grid security by providing fast reserve services. It also supports the production of renewable energy by integrating more green electricity into the grid.
Future Expansion
TotalEnergies plans to deploy similar storage solutions in other countries where it is actively developing renewable energies. The company aims to expand its renewable electricity generation capacity to 35 GW by 2025 and 100 GW by 2030.
