With 62 wind turbines for a total capacity of around 500 MW, the Dieppe-Le Tréport wind farm represents an investment of around €2.7 billion. The project involves the construction and installation of a wind farm located 15 km off Le Tréport city and 17 km off Dieppe city. This offshore wind farm will supply nearly 850,000 people with electricity each year, the equivalent of 2/3 of the inhabitants of the Seine-Maritime department area.

The final investment decision opens the way for the manufacturing and construction phase of the project. From 2024, maritime work will start by the installation of the piles. At the same time, RTE will set up a double submarine connection to transfer the electricity generated at sea to the onshore grid. The installation of the jackets and the electrical substation built by Chantiers de l’Atlantique in Saint-Nazaire will follow. The wind turbines, produced by Siemens Gamesa in its Le Havre facility, will be installed by Jan de Nul Group.

The construction phase of the EMDT wind farm will last 3 years and create 1,300 direct jobs in France. The wind farm is expected to be commissioned in the second half of 2026.

Winner in 2014 of the call for tenders launched by the French State in 2013, the project has been in development since then, implying a continuous dialogue with local elected officials, fisheries and sea users, socio-economic players and the general public. Detailed engineering studies, environmental studies and the creation of a Scientific Interest Group to follow-up the environmental impacts of the wind farm, from its construction to its exploitation, have also been carried out. The administrative authorizations were obtained in 2019.

ENGIE, through Ocean Winds, has now three wind farms under construction in France for a total capacity of 1 GW: the Iles d’Yeu et de Noirmoutier farm, the Dieppe-Le Tréport farm and the Gulf of Lion floating pilot farm. With 15 projects in 7 countries, Ocean Winds has now a portfolio of 1.5 GW of projects in operation and 15.1 GW under construction and in development. With 8 GW won in Scotland and the US in 2022, the ENGIE joint-venture has tripled the size of its project portfolio since its creation in 2019.

We are delighted that a project as strategic as Dieppe-Le Tréport reaches final investment decision. Our 3 projects located in France are now in construction phase. They will contribute to the development of the French offshore wind industry, creating jobs and activity locally. They will play a key role in providing renewable electricity to a large number of households and increasing our energy sovereignty”, says Paulo ALMIRANTE, ENGIE Senior Executive Vice President Renewables, Energy Management and Nuclear.
