Sabella D10 tidal turbine at Ushant Island - Phase 1
The Sabella D10 project was developed with support by ADEME (French Agency for Environment and Energy Management) through the “Investments for the Future” national program. A complementary subsidy from the European Regional Development Fund was awarded by the Brittany region.
The project consisted of the construction and 12-month deployment of an industrial tidal stream generator in Fromveur Passage (also known as St Vincent’s Channel). During slack water periods in May 2015, the cable to export the electricity produced was installed between the generator site and the coast of Ouessant (Ushant). In June 2015, the D10 was lowered into the Fromveur Passage in a water depth of 55 m. By November 2015 the D10 was connected to the Ushant island electrical grid. The D10 was the first tidal turbine to supply electricity to the French grid for testing. In July 2016, at the end of the period for which on-site installation was authorized, the turbine was raised to the surface for technical inspection and expert appraisal.

Site Characteristics
Geographic characterization for the project location:
- Open Ocean: Main body of ocean, not enclosed or partially enclosed by land
- Coastal: Open water near the coast, spanning between land and shelf boundary
- Enclosed Bay: water that is partially surrounded by land, with a mouth open to larger water
- Constricted Channel: A channel where water flows quickly due to narrowing by the land
- River: Water flowing from land towards a larger body of water
