The largest dam in Washington, in terms of structural volume, reservoir capacity, and electricity production, is the Grand Coulee Dam on the Columbia River. It is the largest power station in the United States with a nameplate capacity of 6,809 megawatts and one of the largest concrete structures in the world. [ 3 ]
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.
Lake of the Woods Dam Number Two – near Fredericksburg; Leesville Dam – on the Roanoke River; operated by Appalachian Power as part of the Smith Mountain pumped storage project; Little River Dam (hydroelectric) – on the Little River; owned by the city of Radford; Martinsville Dam – on the Smith River; Martinsville Fish Dam – NRHP ...
The Skagit River Hydroelectric Project is a series of dams with hydroelectric power-generating stations on the Skagit River in the north of the U.S. state of Washington. The project is owned and operated by Seattle City Light to provide electric power for the City of Seattle and surrounding communities.
The upper reservoir is formed on Rocky Mountain above the lower reservoir by a 120-foot (37 m) tall and 12,895-foot (3,930 m) long continuous earth and rock-fill dam. It can store up to 10,650 acre-feet (13,140,000 m 3) of water and its surface area covers 221 acres (89 ha). The upper reservoir lies at an elevation of 1,392 feet (424 m) while ...
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 largest hydroelectric power station is the Three Gorges Dam in China, rated at 22,500 MW in total installed capacity. After passing on 7 December 2007 the 14,000 MW mark of the Itaipu Dam, the facility was ranked as the largest power-generating facility ever built. The dam is 181 m (594 ft) high, 2,335 m (7,661 ft) long and 115 m (377 ft ...
The upper and lower reservoirs are created by earth and rock-filled embankment dams. The upper reservoir dam is 460 feet (140 m) high, 2,200 feet (670 m) long and has a structural volume of 18,000,000 cubic yards (14,000,000 m 3).
