The Rance Tidal Power Station is a tidal power station located on the estuary of the Rance River in Brittany, France. [1]Opened in 1966 as the world's first tidal power station, [2] the 240-megawatt (MW) facility was the largest such power station in the world by installed capacity for 45 years until the 254-MW South Korean Sihwa Lake Tidal Power Station surpassed it in 2011.
Around the same time, the 240 MW la Rance Tidal Power Station was built in Brittany, France, opened in November 1966. [3] La Rance was the largest tidal barrage in world for 45 years, until the 254 MW Sihwa Lake Tidal Power Station was commissioned in South Korea in 2011. [4] However, there are few other examples worldwide.
The Rance Tidal Power Station. This article lists most power stations that run on tidal power, both tidal range (impoundment via a barrage) and tidal stream (harnessing currents). Since tidal stream generators are an immature technology, no technology has yet emerged as the clear standard.
Tidal barrages can generate bulk power on a predictable and reliable schedule. The Rance Tidal Power Station in Brittany, France, which opened in 1966, is still one of the largest tidal power plants in operation. However, tidal barrages require major civil construction works and alter the natural tidal movements in coastal regions.
The Rance tidal power plant built over a period of six years from 1960 to 1966 at La Rance, France. [30] It has 240 MW installed capacity. 254 MW Sihwa Lake Tidal Power Plant in South Korea is the largest tidal power installation in the world. Construction was completed in 2011.
The semi-tidal river flows into the English Channel between Dinard and Saint-Malo. Before reaching the Channel, its waters are barred by a 750 metre long dam forming the Rance tidal power plant. The river is linked to the Vilaine by means of the Canal d'Ille-et-Rance. Départements and towns along the river: Côtes-d'Armor: Collinée, Caulnes ...
But any power produced by the tidal devices had to be dispersed through heaters. The prototypes could be up to 10 feet in diameter, compared to the full-size devices which are 30 to 40 feet wide.
Sihwa Lake Tidal Power Station is the world's largest tidal power installation, with a total power output capacity of 254 MW. When completed in 2011, it surpassed France's 240 MW Rance Tidal Power Station, which was the world's largest for 45 years. It is operated by the Korea Water Resources Corporation.
