Three Gorges Dam

The Three Gorges Dam power project, located on the Yangtze River in central China's Hubei Province, is the world's largest hydroelectric dam. The 2.3-kilometer-long concrete gravity dam is intended to prevent major floods in the Yangtze River's flood-prone upper reaches by directing them downstream. The power plant has a capacity of 22.5 GW and is equipped with 34 turbo generators. It has a 483-meter-long spillway, as well as a left and right powerhouse.

The $31 billion hydroelectric power project, which has been in operation since 2003, is the primary source of electricity in East China, Central China, Guangdong Province in South China, and other areas. In 2020, the Three Gorges Dam set a new world record for yearly power production from a single hydropower plant, generating 111.8 billion kilowatt-hours(kWh). It is owned by China Three Gorges Corporation (CTGC).
