Belgian contractor DEME has installed the first offshore wind substation (OSS) off France, at the 480MW EDF-Enbridge Saint-Nazaire project in the Atlantic.

The 2,100 ton substation was built by a consortium including Atlantique Offshore Energy, the business unit of Chantiers de l’Atlantique dedicated to renewable marine energies, GE Grid Solutions and DEME’s French subsidiary SDI.

Scheduled to be operational next year, Saint-Nazaire will be the first commercial offshore wind farm installed in French waters.
