REGION BRETAGNE - BRETAGNE OCEAN POWER
E14
Description
Brittany is one of France's most active regions in the development of floating offshore wind, with several projects underway or in the pipeline. Pennavel, awarded under the AO5 tender, is currently being developed off the coast of Groix and Belle-Île for a capacity of 250 MW, with commissioning expected in 2031. The AO9 tender provides for a 500 MW extension in South Brittany, while AO10 covers a 1.2 GW project off north-west Brittany, with the call for tenders expected to be published in 2026. The Bretagne Grand Large zone has been identified as a priority area for deep-water floating wind development by 2050.
The region has a structured industrial ecosystem to support these projects: 200 specialised companies (steel and naval construction, marine operations, engineering consultancies), nearly 3,000 researchers in marine science and technology, and a training offering covering more than 60 offshore energy professions.
On the port side, Brest is positioned as the hub for floater assembly and turbine integration, with an offshore renewable energy terminal of over 40 hectares currently being adapted for floating wind as part of the INFLOW project. Lorient completes this setup as a logistics support port for construction, installation and operations & maintenance phases. Each 500 MW project represents a potential of 3,000 jobs around the ports, including 500 direct jobs.
Bretagne Ocean Power, the Regional Offshore Renewable Energy Cluster, brings together all these stakeholders — companies, ports, research and training organisations — under a single banner. For developers, energy companies and tier-1 industrials, the cluster is the gateway to Brittany's supply chain at every stage of your projects.
