France-based DCNS company OpenHydro has successfully deployed the second turbine for EDF's Paimpol-Bréhat tidal array off the coast of Brittany.
The turbine was lowered to seabed with the aid of OpenHydro's deployment barge and is expected to be connected to the grid this summer. Once operational, it will be the first of its kind in the world.
OpenHydro's chief executive James Ives said: "OpenHydro, DCNS, and EDF have worked hand-in-hand to deliver this milestone for the tidal energy industry.
"Paimpol-Bréhat is a global industry first, giving key insights into the operation of our turbines at array scale.
"On a technical and industrial level, it will help us prepare for delivery of EDF Energies Nouvelles' Normandie Hydro project, a 14MW array set to be deployed in 2018.
"This historic achievement is also an essential step on the path to commercialisation and in ensuring OpenHydro is well positioned to benefit from the €200bn tidal energy market, which exists world-wide."
Set to operate at a depth of 40m below the surface, the 16m turbine will be deployed close to the first, which was deployed in January this year.
The array will be connected to a GE-developed submarine converter and will export 1MW of energy to the French electrical grid through a single cable.
