Born of a partnership with the Brittany Region, the project won the ADEME EOLFO Call for Projects in 2016, with the objective to encourage the development of a French industrial sector in floating offshore wind energy. As such, it benefits from State support through investments for the future.

Groix & Belle-Ile’s floating wind turbines will allow the selected technologies to be deployed under real operating conditions. The experience gained will bring us unparallel expertise, prove the bankability of floating offshore wind technology, competitive advantages for future commercial floating wind farms in France and abroad.

Connection to the power grid To transport the electricity produced by the 3 wind between the offshore pilot farm turbines, RTE plans to connect the pilot farm to the Public Power Transmission Network by delivering a 63 000 volt and the onshore network is the via 32 km long subsea and underground power cables responsibility of the RTE, the French to the Kerhellegant substation in Plouharnel. It will be Electricity Transmission Network. routed via a subsea cable to a landing point located in the Kerhillio area of Erdeven and then via a buried cable to the Kerhellegant substation.
NAVIGATION REGULATIONS
Nautical commissions, bringing together sea stakeholders and other users of the sea, have made it possible to establish recommendations that will be taken up by the Maritime Prefecture of the Atlantic (Préfecture Maritime de l’Atlantique) to define the specific navigation regulations applicable to the pilot farm.
Floating wind turbines will be equipped with visual and electronic warning systems to ensure safe navigation © CDPMEM 56 and allowing recreational and fishing vessels to circulate between the units, subject to respecting local regulations and associated minimum safe distance.

A landscape study has been carried-out, considering the main Île, Houat and on the coast from Quiberon to Moëlan-sur-Mer. Here are characteristics of the coastal scenery and heritage. Multiples two examples, based on photos taken with the best possible visibility photomontages have been produced between the islands of Groix, Belle- conditions: bright and clear sky.
