27 Sep 2022: Agnès Pannier-Runacher, Minister for Energy Transition, and Hervé Berville, Secretary of State for the Sea finalised location of the windfarm tender area. The larger call area originally announced for tender has been refined down as part of the tender negotiation phase with bidders. It is located in the eastern part of the call area, more than 20 km from Pointe des Poulains de Belle-Île. The wind farm will feature up to 20 turbines. Candidates will also be encouraged to minimize the final footprint of the park thanks to the introduction in the specifications of a new scoring criterion. The project is located in the public domain so, developers will be liable for an offshore wind tax, which should represent more than 4 million euros per year. throughout the life of the park, divided between the coastal municipalities (50%), the fishing committees (35%), the OFB (10%) and the rescuers at sea (5%). The competitive dialogue phase, which includes the 10 pre-selected bidders, is drawing to a close. The location of the park will be included in the specifications of the call for tenders which will be submitted for the opinion of the Energy Regulatory Commission in the coming weeks, then published. Candidates must submit their offers in early 2023. The winner will be designated by the government in the spring. Commissioning anticipated in 2030.
