16. The Three Gorges Dam The Three Gorges Dam is a Chinese hydroelectric river dam which spans the Yangtze River in Sandouping , Yichang , Hubei province, China . It is the largest hydroelectric river dam in the world, more than five times the size of the Hoover Dam also known as the Boulder Dam.
17. Grand Coulee Dam Grand Coulee Dam is a hydroelectric gravity dam on the Columbia River in Washington . It is the largest electric power producing facility in the United States, and the largest concrete structure in the U.S.
18. Bratsk hydroelectric plant Bratsk hydroelectric plant (named 50 years of Great October ) is a the second level of the Angara River hydroelectric stations cascade in Irkutsk Oblast , Russia . Located near Bratsk . Since its full commissioning in 1967, the station was the world’s single biggest power producer until Canada's Churchill Falls in 1971. Annually the station produces 22.6 billion kWt/h. Currently, the Bratsk Power Station operates 18 hydro-turbines, each with capacity of 250MW, produced by the Leningrad Metal Works .
19. Karun-3 dam The Karun-3 dam is a hydroelectric dam on the Karun river in the province of Khuzestan , Iran . It was built to meet Iran's energy demands as well as to provide flood control. The Karun has the highest discharge of Iran's rivers. The objectives of the construction of Karun III Dam & Hydro-electric Power Plant are electric Power supply and flood control. Karun III power generators are connected to the National Power network as the Peak Power generation. With this power plant being operated, with the capacity of 2000Mw , and an average electric power generation of 4137GW.h/y , a major portion of the electric power shortage in the country will be met.
