Despite the large difference in installed capacity between Three Gorges Dam and Itaipu Dam, they generate nearly equal amounts of electrical energy during the course of an entire year – Itaipu 103 terawatt-hours (370 PJ) in 2016 [1] and Three Gorges 111.8 TWh (402 PJ) in 2020, [2] because the Three Gorges experiences six months per year when ...
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.
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]
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 Andekaleka Dam is a gravity dam on the Vohitra river near Andekaleka in eastern Madagascar.The primary purpose of the dam is hydroelectric power generation and it diverts water from the Vohitra east into a 4 kilometres (2.5 mi) headrace tunnel where it reaches a 91 megawatts (122,000 hp) underground power station.
The Reusens Dam is a 12.5 MW [1] hydroelectric generation facility on the James River near the city of Lynchburg, Virginia, United States.The project includes a concrete gravity dam spanning the left side of river which incorporates eight 16 3/4-foot-high flood gates, a 125 feet long by 25 feet tall concrete arch dam segment with 7 1/4-foot-high flashboards, and two separate power houses ...
Cushman Dam No. 1 is a hydroelectric dam on the North Fork of the Skokomish River in Mason County, Washington, which in derogation of the natural and treaty rights of the Native inhabitants impounded and enlarged the formerly natural Lake Cushman, leading to damage claims in excess of $5 billion and an eventual settlement agreement with the Skokomish tribe that terminates the right to operate ...
