This article provides a list of the largest hydroelectric power stations by generating capacity. Only plants with capacity larger than 3,000 MW are listed. The Three Gorges Dam in Hubei, China, has the world's largest instantaneous generating capacity at 22,500 MW of power. In second place is the Baihetan Dam, also in China, with a capacity of ...
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.
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 .

The amount of hydroelectric power generated is strongly affected by changes in precipitation and surface runoff. [4] Hydroelectric stations exist in at least 34 US states. The largest concentration of hydroelectric generation in the US is in the Columbia River basin, which in 2012 was the source of 44% of the nation's hydroelectricity. [5]
The dam will have a crest width of 635 metres (2,083 ft) with maximum height of 38.5 metres (126 ft). This will form a reservoir with surface area in excess of 30 square kilometres (7,400 acres). Three Pelton turbines will be installed and are expected to generate 82 megawatts of electricity. The energy will be transmitted from the power ...
The dismantling of four hydroelectric dams, which began in June 2023 and has involved hundreds of workers, is the largest dam removal effort in U.S. history.
By 1979 BC Hydro was concerned about the safety of dams built before 1961. A series of earthquakes since then had shown the susceptibility of some dams to liquefaction. [3] A review begun in 1984 discovered the dam was built on loose, saturate sands and silts. The dam was reinforced using injected grout while under full pool. [4]
