Offshore Wind: 300 French companies to build Yeu-Noirmoutier

By ENGIE - 20 June 2025 - 17:23

The offshore wind farm of the Îles d'Yeu et de Noirmoutier (EMYN, led by Ocean Winds, the joint venture of ENGIE and EDPR in offshore wind power) recently erected its first turbine:the whole farm should be installed by October. It was an opportunity for Catherine MacGregor, CEO of ENGIE, to highlight, during a visit to the site in the presence of the Minister for Industry and Energy and several elected officials, that these 61 wind turbines will produce enough decarbonized energy to power 800,000 people, more than the population of the Vendée region. A local energy, produced by a wind farm built through collaboration with numerous local companies.

Construction, which began in 2023, involves more than 300 French companies, including a hundred regional ones: 

  • The substation was built by the Chantiers de l'Atlantique in Saint Nazaire (find out more).
  • The slewing rings are supplied by Rollix Defontaine – the only regional company to have been selected by a French offshore wind farm to manufacture this part. 
  • The core cables are designed in Île-de-France by Prysmian. 
  • The support vessels, which are used for logistics operations, are equipped by French companies such as Louis Dreyfus Armateur, TSM, STO Logistique, AMS and Alka Marina.

In total, 1,600 direct and indirect jobs have been created by construction phase, including 1,000 in Le Havre for blades and nacelles manufacturing.

By the end of November, the entire wind farm will produce energy for the grid for a period of 25 years. This operational phase will generate 85 permanent direct jobs, 60 of which will be for the operation and maintenance of the wind farm, located on the Île d’Yeu base.

Proof that renewable energies also energize local industries.
