There are many sources of renewable marine energy, but they do not offer the same degree of technological maturity. EDF has long exploited the power of tidal energy at its La Rance plant in Brittany. It also contributes its expertise to the development of the tidal turbine industry, through the Paimpol-Bréhat sea testing site in Brittany.

The energy of the tides

Tidal power uses the water level differential between the tides to generate electricity. A pioneer in this field, EDF has been developing this energy since 1966, thanks to its plant built at the mouth of La Rance, in Brittany.

Hydropower

Hydropower harnesses the kinetic energy contained in the ocean’s tidal currents to produce electricity. For several years, EDF has been contributing its expertise to the development of the tidal turbine industry through the Paimpol-Bréhat sea testing site in Brittany.
