France Reaches 2,000 MW Offshore Wind Capacity: France Commissions Next Offshore Wind Farm – Dieppe–Le Tréport Nearing Launch

Paris (France)– France is accelerating the expansion of offshore wind energy. The Dieppe–Le Tréport Offshore Wind Farm off the French coast is in an intensive construction phase in spring 2026 and, according to current project data, remains on schedule. Full commissioning is planned for the second half of 2026.

Construction progress is already well advanced: more than half of the 62 jacket foundations have been installed. Work is expected to be completed by summer 2026. At the same time, a new operations and maintenance base was officially opened at the port of Dieppe, which will later host around 70 to 80 employees.

Grid connection is already in place: the export cables to the French electricity grid have been laid and connected. Installation of the 62 Siemens Gamesa wind turbines, each with a capacity of around 8 MW, is scheduled to begin in May or June 2026. The first turbines are expected to start feeding electricity into the grid in summer, with full commissioning expected by the end of 2026.

The wind farm has an installed capacity of around 496 MW and is expected to generate approximately 2 billion kWh of electricity annually—enough to supply roughly 850,000 people. The project is operated by a consortium consisting of Ocean Winds, Sumitomo Corporation, and Banque des Territoires.

The offshore wind farm is located around 15 to 17 kilometers off the coast in Normandy and covers an area of about 83 square kilometers.

France currently has around 2,000 MW of offshore wind farms in operation. These include Saint-Nazaire (Banc de Guérande) with 480 MW, Fécamp (Hautes falaises) with 497 MW, Baie de Saint-Brieuc with 496 MW, and Îles d’Yeu et Noirmoutier with 488 MW.

In addition, France already operates two floating offshore wind farms with a combined capacity of 55 MW. The demonstration projects Provence Grand Large (25 MW) and Éoliennes Flottantes du Golfe du Lion (30 MW) are in operation. A third pilot project, EolMed (30 MW), is in the final installation phase off Port-La Nouvelle.

France considers floating offshore wind energy a strategic future field within key industrial and energy policy frameworks such as “France 2030” and the multiannual energy programming (PPE). The state aims to industrialize this still young technology, position France internationally as a major player in the sector, and build a strong domestic value chain across the entire industrial process—from development to manufacturing to installation.
