France: First Wind Turbine Installed at 500 MW Dieppe Le Tréport Offshore Wind Farm
Dieppe (France) – The expansion of offshore wind energy in France has reached another milestone. Ocean Winds has installed the first wind turbine at the Dieppe Le Tréport Offshore Wind Farm. With a total installed capacity of 500 megawatts (MW), the project is expected to generate enough electricity to supply around 850,000 people once completed and is scheduled to begin first power generation in the coming weeks.
Dieppe Le Tréport Offshore Wind Farm Moves into Power Generation Phase
The installation of the first turbine marks the project's transition from the construction phase to the operational phase. Ocean Winds is developing the wind farm and is leading its implementation as the majority shareholder. The company is a joint venture between EDP Renewables and Engie.
According to Ocean Winds, several offshore wind projects are currently progressing simultaneously in France. Since the beginning of 2026, the company has fully commissioned the Îles d'Yeu et de Noirmoutier Offshore Wind Farm and achieved first power generation at the Éoliennes Flottantes du Golfe du Lion floating offshore wind project.
France Relies on a European Value Chain for Offshore Wind Projects
The Dieppe Le Tréport project is based on a European industrial and supply chain. Siemens Gamesa is supplying SG 8.0-167 DD wind turbines, each with a rated capacity of 8 MW, while nacelles and rotor blades are manufactured primarily at the company's Le Havre facility. Tower sections are produced in Bilbao and pre-assembled in Brest. The foundations are manufactured in Fene, Spain, and stored in Cherbourg prior to installation.
The offshore substation was built by Chantiers de l'Atlantique in Saint-Nazaire, while the subsea export cables are supplied from Greece. Offshore installation work is being carried out by the Belgian infrastructure companies Jan De Nul and DEME Group, among others. Numerous ports along the French coast are supporting the project's logistics.
Offshore Wind Energy in France
France currently has an installed offshore wind capacity of nearly 2,000 MW (2 GW). To date, this capacity has been provided almost entirely by bottom-fixed offshore wind farms. With the Éoliennes Flottantes du Golfe du Lion project, floating offshore wind technology is also reaching its next stage of development.
To further expand offshore wind energy, France launched a tender in 2026 for approximately 10 GW of new offshore wind capacity. The tender covers both bottom-fixed offshore wind farms and floating projects and is intended to significantly accelerate the expansion of the country's offshore wind capacity.
Alongside expanding renewable electricity generation, France is also pursuing industrial policy objectives through its offshore wind strategy. The government aims to establish a European value chain for offshore wind energy, spanning turbine manufacturing, maritime infrastructure, installation, and maintenance. Projects such as Dieppe Le Tréport are intended to combine the expansion of offshore wind energy with industrial development and regional value creation.
