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.
The Ngoulmendjim Power Station is a planned hydroelectric power station across the Komo River in Gabon. The power station is under development, by a consortium comprising the French conglomerate Eranove Group and Gabonese Fund for Strategic Investments (FGIS). As of November 2021, the development was in the "financial mobilization phase". [1]
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.
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]
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 ...
The Kajaki Dam is "an earth and rockfill embankment type dam" [4] located on the Helmand River in the Kajaki District of Helmand Province in Afghanistan, about 161 km (100 mi) northwest of Kandahar. It has a hydroelectric power station , which is operated by the Helmand and Arghandab Valley Authority through the Ministry of Energy and Water .
The Santo Antônio Dam is designed as a run-of-the-river hydroelectric dam, power plant, and factory. The dam itself is 13.9 m (46 ft) tall and 3,100 m (10,171 ft) long, creating a reservoir with a surface area of 271 km 2 (105 sq mi), of which 164 km 2 (63 sq mi) is the previously existing river channel.
