The U.S. Energy Information Administration (EIA) refers to capacity as the maximum output of electricity that a generator can produce under ideal conditions.
The Three Gorges Dam is a hydroelectric gravity dam that spans the Yangtze River by the town of Sandouping, in Yiling District, Yichang, Hubei province, China, and is the world's largest power station in terms of installed capacity (22,500 MW). The dam was expected to provide 10% of China's power. However, electricity demand has increased more quickly than previously projected. Even fully operational, on average, it supports only about 1.7% of electricity demand in China in the year of 2011, when the Chinese electricity demand reached 4692.8 TWh.
The largest dam in Asia by installed capacity is Three Gorges Dam of China with a capacity of 22,500 MW. The second largest dam by installed capacity is Xiluodu Dam with 13,860 MW, while the third largest is Wudongde Dam at 10,200 MW.The installed capacities of major dams in Asia range from 100 MW to 22,500 MW, with the average being 3,839.0 MW.
