Ocean Winds has reached a significant construction milestone at the Dieppe Le Tréport offshore wind farm off the Normandy coast of France, completing the installation of the project's first wind turbine on June 15, 2026, with the 500 MW facility now expected to begin generating electricity within weeks.

Project Scale and Timeline

The Dieppe Le Tréport offshore wind farm, known as EMDT, will ultimately comprise 62 wind turbines positioned off the coast of Le Tréport and Dieppe. At full build-out, the facility is designed to supply renewable electricity equivalent to the annual consumption of approximately 850,000 people.

With the offshore substation already in place prior to the first turbine installation, Ocean Winds says the project will achieve first power in the coming weeks as turbines are connected to the grid one by one, creating a progressive ramp-up of electricity production.

Ocean Winds, the international offshore wind company jointly owned by EDP Renewables and ENGIE, serves as majority shareholder and is leading both the development and delivery of the project, as well as its future operations.

Marc Hirt, Country Manager for Ocean Winds in France, said the installation reflects the pace at which the company is advancing offshore wind across the country.

"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," he said.

A Strong Year for Ocean Winds in France

The Dieppe Le Tréport milestone comes amid what Ocean Winds describes as a year of strong delivery in France. Since the start 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 characterizes this concurrent progress across different technology types and project phases as evidence of its ability to execute multiple large-scale offshore energy developments simultaneously within a single country.

European Supply Chain Anchored in France

The installation at Dieppe Le Tréport draws on a broad European industrial supply chain, with a substantial portion of manufacturing activity taking place in France itself.

Siemens Gamesa is supplying the wind turbines, with nacelles and blades produced primarily at its facility in Le Havre. Tower sections are manufactured in Bilbao and pre-equipped in Brest before being transported offshore. Foundations are manufactured in Fene, Spain, and stored in Cherbourg ahead of installation.

The offshore substation for the project was constructed at Chantiers de l'Atlantique in Saint-Nazaire, one of France's most prominent shipbuilding and marine engineering facilities.

Subsea cables for the project are produced in Greece. Offshore installation works are being carried out by contractors Jan De Nul and DEME, with multiple ports along the Channel and North Sea coastline supporting the project's logistics operations.

Frédéric Flaus, Project Director for EMDT, emphasized that the first turbine installation represents the culmination of years of preparation and coordination. "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," he said.

Construction and Generation to Advance Together

With the first turbine now in place and the offshore substation already operational, the Dieppe Le Tréport project is entering a phase where construction activity and electricity generation will occur in parallel.

Each turbine, as it is installed and connected to the grid, will begin contributing to renewable power production for France, meaning the wind farm will generate increasing volumes of electricity throughout the remainder of the installation campaign rather than waiting for full completion before commencing operations.

Ocean Winds said the project's transition into this combined construction-and-generation phase marks a new stage in its delivery, with teams focused on maintaining both the pace of installation and the safe integration of turbines into grid-connected operation.
