Operating Tidal Power Schemes
- The first tidal power station was the Rance tidal power plant built over a period of 6 years from 1960 to 1966 at La Rance, France. It has 240 MW installed capacity.
- The first tidal power site in North America is the Annapolis Royal Generating Station, Annapolis Royal, Nova Scotia, which opened in 1984 on an inlet of the Bay of Fundy. It has 18 MW installed capacity.
- The first in- stream tidal current generator in North America (Race Rocks Tidal Power Demonstration Project) was installed at [(Race Rocks)] on Southern Vancouver Island in September 2006. The [(next phase in the development)] of this tidal current generator will be in Nova Scotia.
- A small project was built by the Soviet Union at Kislaya Guba on the Barents Sea. It has 0.5 MW installed capacity. In 2006 it was upgraded with 1.2MW experimental advanced orthogonal turbine.
- Another 12MW project at Kislaya Guba in Russia with orthogonal turbines is under construction.
- China has apparently developed several small tidal power projects and one large facility in Jiangxia.
- China is also developing a tidal lagoon near the mouth of the Yalu.
- Scotland has committed to having 18% of its power from green sources by 2010, including 10% from a tidal generator. The British government says this will replace one huge fossil fuelled power station.
- South African energy parastatal Eskom is investigating using the Mozambique Current to generate power off the coast of KwaZulu Natal. Because the continental shelf is near to land it may be possible to generate electricity by tapping into the fast flowing Mozambique current.
