The Xilingxia reach of the Yangtze River and Gezhouba Hydropower Station in the lower reaches of Yichang City, Hubei Province constitute a cascade hydropower station. The Three Gorges Dam is the largest hydropower station in the world and the largest engineering project in China. However, due to many problems such as migration and environment, it was accompanied by great controversy from the beginning of preparation.

The Three Gorges Hydropower Station has more than ten functions such as shipping, power generation and planting. 1992, the National People's Congress approved the construction of the Three Gorges Hydropower Station. 1994 started, in the afternoon of June 2003 1, and was completed in 2009.

The equipment is mainly provided by VGS consortium composed of Voith, General Electric, Siemens, Alstom and ABB. When signing the supply agreement, they promised to transfer relevant technologies to domestic manufacturers free of charge. The power transmission and transformation system of Three Gorges Hydropower Station will be built and managed by China State Grid Corporation. It is estimated that 15 500 kV transmission lines will be installed to connect to the regional power grid.

The dam height is185m, the water storage height is175m, the reservoir length is 2,335m, the total investment is 95.46 billion yuan, and there are 32 hydropower units with a capacity of 700,000 kilowatts. Finally, the Three Gorges Hydropower Station was put into operation on July 4, 20 12, which means that the installed capacity of the Three Gorges Hydropower Station is 22.4 million kilowatts. On July 4th, 20 12, it became the largest hydropower station and clean energy production base in the world.
