It will be the first of its kind in France.
By 2023, a floating wind farm must be installed off Belle-Ile and the island of Groix in Morbihan.
The authorities are now looking for its operator with a call for applications open until July 1, which has just been published on the website of the Energy Regulatory Commission (CRE).
"The purpose of the project is to build and operate a floating wind farm with an installed capacity of between 230 and 270 Megawatts", indicates CRE.
Barbara Pompili, the Minister for the Ecological Transition had declared in January that it would even be "the first commercial park of floating wind turbines in Europe".
Only pilot sites for now
Its precise location has not yet been decided.
The future park "will represent a crucial stage for the further development of wind power," France Wind Energy said in a press release.
“This is the first commercial call for tenders for floating wind turbines of this size in France and around the world,” said industry manufacturers.
Floating wind turbines, which are the subject of pilot sites at this stage, can be set up regardless of the depth, in particular far from the coast.
