Technical FAQs 4

What is the biggest battery energy storage system in France?

The biggest battery energy storage system (BESS) in mainland France went into operation in late January, and will provide grid-balancing services to national transmission system operator RTE. France-headquartered multinational energy company Total was contracted by RTE for the project, which has 25MWac rated output and 25MWh of storage capacity.

Where is a lithium-ion battery based energy storage system built?

It has been built at the site of a former oil refinery operated and owned by Total in Dunkirk, in northern France. The lithium-ion battery energy storage system used for the project was provided by battery and energy storage provider Saft, which Total owns.

Who provides lithium-ion battery energy storage?

The lithium-ion battery energy storage system used for the project was provided by battery and energy storage provider Saft, which Total owns. Engineering procurement and construction (EPC) duties including civil works and system integration services were provided by Omexom, which announced the project’s completion in late January.

Does France have a battery storage system?

Some of France’s island territories have got fairly sizeable battery storage systems to underpin their local energy autonomy, but in continental France, development is still at a relatively early stage compared to say, Germany or the UK.
