Ocean Winds has achieved first power at the 496MW Îles d’Yeu and Noirmoutier (EMYN) offshore wind farm, marking its first delivery of electricity from offshore wind in France.
The milestone comes just weeks after installation of the first turbine, with initial units now supplying power to the national grid following testing that began on 23 May.
The wind farm, located off the Vendée coast, is expected to reach full commissioning by the end of 2025.
“This major milestone – first power supplied to the national grid – marks not only a technical achievement for the project but also a defining moment for Ocean Winds,” said Marc Hirt, country manager France at Ocean Winds.
“The EMYN project not only contributes to France’s energy transition but also reinforces the strength of the country’s offshore wind industry, built on a strong European and local supply chain,” he added.
Grid infrastructure for the project, including offshore and onshore components, was developed and is operated by French transmission system operator RTE.
“The first megawatt hours produced by EMYN are the result of meticulous coordination at sea and on land,” said Frédéric Flaus, EMYN project director.
Ocean Winds is currently building two other offshore wind farms in France-Dieppe-Le Tréport and EFGL-and recently secured a 250MW floating wind project in the Mediterranean alongside Banque des Territoires.
