Inside the Robert-Bourassa generating station, in northern Quebec, the world's largest underground power station, with an installed capacity of 5,616 MW.. An underground power station is a type of hydroelectric power station constructed by excavating the major components (e.g. machine hall, penstocks, and tailrace) from rock, rather than the more common surface-based construction methods.
Hoover Dam's initial 1,345 MW power station was the world's largest hydroelectric power station in 1936; it was eclipsed by the 6,809 MW Grand Coulee Dam in 1942. [20] The Itaipu Dam opened in 1984 in South America as the largest, producing 14 GW , but was surpassed in 2008 by the Three Gorges Dam in China at 22.5 GW .
This dam slows a normally fast and shallow river for partial diversion to a hydroelectric dam. The diversion tunnel opening can be seen in the upper left. The Imperial Dam diverting the Colorado River in the southwestern United States. A diversion dam is a dam that diverts all or a portion of the flow of a river from its natural
The Hoover Dam in Arizona and Nevada was the first hydroelectric power station in the United States to have a capacity of at least 1,000 MW upon completion in 1936. Since then numerous other hydroelectric power stations have surpassed the 1,000 MW threshold, most often through the expansion of existing hydroelectric facilities.
[4] [5] The Project is called Grand Inga and is planned to be realised on the lower Congo River. [6] As of 2014, China is working on a 50,000 MW [7] dam as part of the Yarlung Tsangpo Hydroelectric and Water Diversion Project. Another proposal, Penzhin Tidal Power Plant, presumes an installed capacity up to 87,100 MW.
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A ...

A tidal barrage is a dam-like structure used to capture the energy from masses of water moving in and out of a bay or river due to tidal forces. [1] [2] Instead of damming water on one side like a conventional dam, a tidal barrage allows water to flow into a bay or river during high tide, and releases the water during low tide.
