Paimpol-Bréhat Tidal Test Site
  • Type of Testing Current
    Year Established 2012
    Temperate/Tropical Temperate
    Commercial/Array/Full scale/Scale Full Scale
    Development Status Operational


    The Paimpol-Bréhat tidal test site started in 2010. It is located 12 km from shore, in an open sea environment (exposed to waves). A 15 km long DC subsea cable embedding optical fibres was installed in 2012. In 2015, the cable end was equipped with a wetmate connection for DC power and optical circuits.
    OpenHydro turbines were tested on site from 2010 to 2017. Since June 2019, HydroQuest 1MW turbine is connected.
