The region boasts key industrial assets for developing marine renewables on a large scale. With its long-standing skills, innovation and international industry players, Pays de la Loire has turned marine renewables into an industrial success over the years.

Pays de la Loire, the new maritime economy

With its considerable shipbuilding and industrial heritage, the region has large-scale capacity, a long-established multi-industry base (shipbuilding, aerospace, composities, oil and gas) and efficient logistics and port services.

This solid background has made Pays de la Loire one of France’s major industrial regions and puts it in good stead to address the challenges of the new maritime economy (marine renewables, fishing fleets of the future, protection and sustainable use of marine resources).

Floatgen: France's first grid-connected floating wind turbine

Installed 22 km off the French Atlantic coast and designed by IDEOL, the Floatgen floating wind turbine went into action on 18 September 2018. The 2 MW device, the first of its kind in France, is connected to the national grid via an export cable and is set to generate enough power for the needs of 5,000 inhabitants.

Floatgen will undergo tests for two years at the SEM-REV offshore test site operated by Centrale Nantes.
