The Rance Tidal Power Station is the world's first tidal power station and also the world's second biggest tidal power station. The facility is located on the estuary of the Rance River, in Brittany, France. Opened on 26 November 1966, it is currently operated by Électricité de France, and is the second largest tidal power station in the world, in terms of installed capacity, since the Sihwa Lake Tidal Power Station surpassed it after 45 years. With a peak rating of 240 Megawatts, generated by its 24 turbines, it supplies 0.012% of the power demand of France. With a capacity factor of approximately 26%, it supplies an average 62 Megawatts, giving an annual output of approximately 540 GWh. The barrage is 750 m (2,461 ft) long, from Brebis point in the west to Briantais point in the east. The power plant portion of the dam is 332.5 m (1,091 ft) long. The tidal basin measures 22.5 km2 (9 sq mi).
