Since 1967, the La Rance tidal power plant, near Mont Saint Michel, generated annually 600 million kWh using its 24 turbines of 10 MW.

During the first 30 years of operation, the 24 turbines of the Rance facility has operated without major incidents or breakdowns for 160,000 hours and generated 16 billion kWh at the price of 2.8 cEuro per kilowatt-hour, a highly competitive price and one that is lower than Electricité de France's average generation costs.
