Switzerland-based energy storage owner-operator BW ESS has acquired two standalone battery energy storage projects in France from Recurrent Energy, a subsidiary of Canadian Solar. Each project is rated at 100 MW/400 MWh, giving a combined platform of 200 MW/800 MWh.

Location and development status

The projects are located in Calvados in Normandy and in the Eastern Pyrenees. Both are described as being at an advanced stage of development. France becomes BW ESS's seventh market, extending a European footprint that has expanded quickly through 2026.

The transaction splits development and ownership along a clean line. Recurrent Energy will continue to lead the two projects through the remaining development phase until ready-to-build status is reached. BW ESS will then build, own and operate them as long-term assets, applying its construction, optimisation and asset-management experience.

Why France, and why standalone

France has a strong nuclear base but a growing need for flexibility as weather-sensitive demand and an evolving generation mix create more variable system conditions.

That was the rationale offered by BW ESS CEO Erik Strømsø. The standalone batteries are intended to absorb surplus power, provide rapid-response flexibility services to the French power system and make low-carbon generation available when it is most valuable.

The logic is notable because France's decarbonised generation mix is often presented as reducing the need for storage. The counter-argument — that a nuclear-heavy system with weather-sensitive demand still needs fast, short-duration flexibility and intraday shifting — is gaining traction among investors.

A busy year for BW ESS

The French acquisition caps an active period for the company. In September 2026, BW ESS acquired two projects totalling 126 MW and up to 675 MWh in Valencia, Spain, and it has since secured debt financing for the 400 MW/1.424 GWh Hams Hall BESS in England.

France's own storage market is also building momentum. Earlier in October 2026, Saft signed contracts with Axpo for two BESS in France totalling 55 MW/122 MWh — a smaller but complementary set of projects that underlines how both industrial suppliers and financial owners are positioning for French flexibility demand.

Read-across for the EU market

The deal structure — developer retains the risk of securing permits and grid terms, owner-operator steps in at ready-to-build — is becoming a template for European storage transactions. It allows specialist developers to recycle capital while long-term owners acquire de-risked assets with predictable construction pathways. For France, the arrival of a new owner-operator with multi-market experience signals that standalone storage is moving from the demonstration phase into the infrastructure phase.
