Your project can be accelerated in Brittany with open sea test sites for offshore wind and marine energy technologies

3 open sea test sites, equipped to host tidal, wind or wave technologies are open to you.

With its ideal geographical configuration and a tissue of proven expertise, Brittany is currently offer you the ability to test your project on 3 test sites:


Controlled-Cost Sites

Each test site has its own specific features. However, they all have things in common:

  • They are easy to operate (with qualified labour available to operate and maintain technologies in the areas of research, marine operations, ship building and repair).
  • All at controlled costs.

Additional Sites

The site in Sainte-Anne-du-Portzic (bay of Brest) is managed by Ifremer and that in the ria d’Etel managed by Chantier Bretagne Sud are used to test reduced-scale machines or applications. The sites are complementary: the first for wind or wave energy, the second for tidal turbines.

Offshore Tidal Turbine

The site in Paimpol-Bréhat is operated by EDF. It is the only full-scale pilot site for offshore tidal turbines. It also has the advantage of being connected to the grid by means of a direct current cable. The Grenoble company HydroQuest and its partner CMN (Constructions Mécaniques de Normandie) successfully tested their 1MW marine tidal turbine HydroQuest Ocean.

The project will build cross-border partnerships to develop new technologies, test and demonstrate up to 8 MW of new tidal capacity at a number of locations around the Channel region, and use the learning from this development to make a stronger, cost-effective case for tidal energy as part of the France/UK energy mix.  The project is the largest ever to be approved not only by the France (Channel) England Programme but by any Interreg programme.
