Floatgen Floating Offshore Wind Turbine exports first kWh to France's grid from SEM-REV off Le Croisic, showcasing Ideol's concrete floating foundation by Bouygues and advancing marine renewable energy leadership ambitions.
Breaking Down the Details
A grid-connected demo turbine off Le Croisic, proving Ideol's floating foundation at SEM-REV.
First French offshore floating wind unit, 22 km off Le Croisic.
Exported first kWh to grid on 18 September, now operational.
Uses Ideol's patented concrete floating foundation by Bouygues.
Connected via SEM-REV test site's export cable by Centrale Nantes.
Power can supply about 5,000 people; second unit planned in Japan.
Floating offshore wind turbine Floatgen, the first offshore wind turbine installed off the French coast, exported its first KWh to the electricity grid, echoing the offshore wind power milestone experienced by U.S. customers recently.
The connection of the electricity export cable, similar in ambition to the UK's 2 GW substation program, and a final series of tests carried out in recent days enabled the Floatgen wind turbine, which is installed 22 km off Le Croisic (Loire-Atlantique), to become fully operational on Tuesday 18 September.
This announcement is a highly symbolic step for the partners involved in this project. This wind turbine is the first operational unit of the floating foundation concept patented by Ideol and built in concrete by Bouygues Travaux Publics. A second unit of the Ideol foundation will soon be operational off Japan. For Centrale Nantes, this is the first production tool and the first injection of electricity into its export cable at its SEM-REV test site dedicated to marine renewable energies, alongside projects such as the Scotland-England subsea power link that expand transmission capacity (third installation after tests on acoustic sensors and cable weights).
This announcement is also symbolic for France since Floatgen lays the foundation for an industrial offshore wind energy sector and represents a unique opportunity to become the global leader in floating wind, as major clean energy corridors like the Canadian hydropower line to New York illustrate growing demand.
With its connection to the grid, SEM-REV will enable the wind turbine to supply electricity to 5000 inhabitants, and similar integrated microgrid initiatives show how local reliability can be enhanced.
