Enertrag plans €1.1 billion French wind-and-battery hub buildout

German renewable energy developer Enertrag has announced a €1.1 billion ($1.28 billion) investment program in France through 2030, targeting 1 GW of installed capacity through energy hubs combining wind generation and battery storage to increase grid flexibility and improve renewable energy integration.

The announcement was made June 1 at the ninth Choose France summit at the Palace of Versailles. Enertrag plans to commission at least 100 MW of renewable energy and battery storage per year in France under the program, with projects structured as hybrid energy hubs combining generation, storage, and controllability.

Two hubs illustrate the model. In the Hauts-de-France region of northern France, a 120 MW hub combining two wind farms with a battery storage installation is scheduled for commissioning in 2027. In the Nouvelle-Aquitaine region of southwestern France, a 110 MW hub will combine three wind farms with battery storage, with no commissioning date disclosed. Further hubs based on the same architecture are in preparation across France, the company said.

Enertrag SE CEO Dr. Gunar Hering said France is one of the company’s strategic core markets and that the investment plan reflects more than 25 years of engagement with the French energy market. Vincent Masureel, managing director of ENERTRAG France, said the Energy Hub configurations combine renewable generation, storage, and controllability to address growing grid flexibility challenges.

Enertrag produces approximately 2,800 GWh of electricity annually from wind and solar across its own assets globally. It has been expanding its battery storage activity alongside its wind portfolio. The company announced a 60 MW/130 MWh grid-scale storage system in Tantow, Brandenburg in May 2025, developed through a joint venture with Green Flexibility and planned for commissioning in early 2026.
