[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.
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.
Where a dam serves multiple purposes, a hydroelectric station may be added with relatively low construction cost, providing a useful revenue stream to offset the costs of dam operation. It has been calculated that the sale of electricity from the Three Gorges Dam will cover the construction costs after 5 to 8 years of full generation. [ 42 ]
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.

The project is owned and operated by Seattle City Light to provide electric power for the City of Seattle and surrounding communities. In 2012, hydro-electric dams provided approximately 89.8 percent of the electricity used in Seattle. [2] The Skagit Hydroelectric Project alone accounts for about 20 percent of Seattle City Light's electricity.
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 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.
