The Dieppe Le Tréport offshore wind farm has installed its first turbine, moving the 500 MW French project closer to first power and renewable electricity generation.
Ocean Winds has announced the installation of the first wind turbine at the Dieppe Le Tréport offshore wind farm in France.
The milestone marks a major step in construction of the 500 MW offshore wind project, located off the coast of Le Tréport and Dieppe.
With the offshore substation already installed, the first turbine is expected to start generating electricity in the coming weeks as turbines are progressively connected to the grid.
The project is being delivered by Ocean Winds, the offshore wind company jointly owned by EDP Renewables and ENGIE. Ocean Winds is the majority shareholder in the project and is leading its development, construction and future operations.
Dieppe Le Tréport offshore wind farm reaches turbine milestone
The Dieppe Le Tréport offshore wind farm will comprise 62 wind turbines with a total installed capacity of 500 MW.
Once complete, the project is expected to supply renewable electricity equivalent to the annual consumption of around 850,000 people.
The wind farm is part of France’s growing offshore wind build-out and follows earlier construction milestones at the site, including the installation of its offshore substation.
Ocean Winds’ official Dieppe Le Tréport project page describes the project as a joint venture between Ocean Winds, Sumitomo and Banque des Territoires.
First power expected in coming weeks
The first installed turbine is expected to begin producing renewable electricity in the coming weeks.
Ocean Winds said turbines will be connected one by one to the grid, allowing power production to increase progressively as offshore installation continues.
The project is now moving into a phase where construction and electricity generation will advance at the same time.
Marc Hirt, Country Manager for Ocean Winds in France, said: “The installation of the first turbine at Dieppe Le Tréport illustrates the scale and pace at which Ocean Winds is progressing offshore wind in France. Delivering this milestone while advancing several projects simultaneously across the country demonstrates the strength of our teams and our integrated approach. From bottom-fixed to floating technologies, across multiple regions, we are contributing to delivering clean, reliable energy and supporting the development of a strong industrial sector.”
Ocean Winds highlights French offshore wind progress
The turbine installation comes during a year of significant activity for Ocean Winds in France.
Since the beginning of 2026, the company has brought the Îles d’Yeu et de Noirmoutier offshore wind farm into full operation and delivered first power from the Éoliennes Flottantes du Golfe du Lion floating wind project.
Ocean Winds said these milestones show its ability to deliver across different offshore wind technologies and project phases at the same time.
Frédéric Flaus, Project Director for EMDT, added: “This first turbine installation is the result of several years of preparation and close cooperation between all parties involved. The project relies on a strong and largely European supply chain, while maintaining continuous dialogue with local stakeholders and sea users to ensure its successful integration at sea. As installation progresses, our teams remain fully focused on delivering the project safely and efficiently.”
European supply chain supports project delivery
The Dieppe Le Tréport offshore wind farm is also supported by a European industrial supply chain.
Siemens Gamesa is supplying the wind turbines, with nacelles and blades mainly produced at its Le Havre facility. Tower sections are produced in Bilbao and pre-equipped in Brest.
Foundations are manufactured in Fene, Spain, and stored in Cherbourg ahead of installation. The offshore substation was built by Chantiers de l’Atlantique in Saint-Nazaire, while subsea cables are produced in Greece.
Offshore installation work is being carried out by contractors including Jan De Nul and DEME, with ports along the Channel and North Sea coastline supporting project logistics.
CGN has previously reported on Ocean Winds’ installation of the first foundation at the project. Read more here: Ocean Winds installs first foundation at Dieppe–Le Tréport offshore wind farm.
