Energy major Total has lifted the lid on a project that aims to construct the largest battery storage facility in France. It could help boost the growth of intermittent renewable power in the French energy mix.

The 25 megawatt (MW) capacity battery power storage facility in Dunkirk, northern France, will be used to provide fast power reserve services to support the stability of the French electricity grid, the company said, according to Euractiv.com.

Total, like other oil majors, is expanding its foothold in the renewables energy sector.

It plans to invest around $2 billion annually to grow its low carbon business, and increase its renewable energy generation capacity to 25 gigawatts by 2025 from around 6GW currently.
