Total announced Thursday its plans to build France’s largest battery-based energy storage project, supporting its goal to become “the responsible energy major,” Kallanish Energy reports.

The new lithium-ion energy storage system will have a storage capacity of 25 megawatt hours (MWh) and output of 25 MW of power. The €15 ($16.7) million project will provide fast reserve services to support the stability of the French power grid.

The facility will be located at the Flandres Center in Dunkirk and should be commissioned late this year. It will be manufactured by Saft at its production site in Bordeaux.

Total’s CEO Patrick Pouyanné said the project is part of the company’s strategy “to develop the stationary energy storage solutions that are critical to the expansion of renewable energy, which is intermittent by nature.”

The plan is for low-carbon electricity operations to account for 15-20% of Total’s sales mix by 2040. The company currently has around 7,000 MW of gross low-carbon powergen capacity, of which over 3,000 MW are from renewables.
