France's first offshore wind installation, the FloatGen floating prototype, has exported its first kWh to the electricity grid, developer Ideol reports.

The connection of the unit’s export cable and a final series of tests were carried out in recent days, with the EU-backed €25m ($29.2m) project becoming fully operational on 18 September.

“This 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,” said Ideol.
