 The Rance tidal power plant uses the energy of the tides of the Channel to generate electricity. Its construction lasted three years and ended on November the 26th, 1966, when it was inaugurated by the French President Charles de Gaulle. It was then connected to the EDF network on December the 4th, 1967. The tidal power plant is the main source of electricity in the Britany region and supplies 240 megawatts. To work, the factory needs to have a difference in water depth of 10-15 meters, naturally generated by the tides.
