Shell, CGN Europe Energy and Caisse des dépôts abandoned plans for for the
Groix & Belle-Île floating wind farm proposed to be installed off the coast of Brittany, France due to rising costs.

The Groix & Belle-Île pilot wind farm was selected as winner of the ADEME’s call for floating demos in 2016. Located 22 km offshore in water depths of 60 metres, the project aimed to  test several technological innovations adapted to a floating environment. It was set to feature three turbines installed atop a semi-Submersible platforms designed by Naval Energies.

According to a statement from Shell: "The project faced several technical, commercial and financial challenges, all in a context of constantly increasing costs and very strong constraints, in terms of inflation and supply chain. The economic conditions linked to the project have been significantly modified, calling into question, for all the partners of the consortium, the economic viability of the project.”

Previously, GE had been scheduled to supply turbines, but it withdrew from several projects earlier this year. MHI Vestas was selected for its
9.5 MW turbine, which is one of the most powerful on the market at the present time.
