Wudongde Dam meets Guangzhou's annual electricity demand.

The average annual power generation of Wudongde Dam can meet one third of Guangzhou's annual electricity demand.

Wudongde hydropower station has a total installed capacity of102,000 kilowatts, and the average annual power generation will reach 389 1 100,000 kwh after it is fully put into operation, ranking seventh in the world, and it is also the largest hydro-generator set in the world. The implementation of "power transmission from west to east" is a major national project. A total of 12 hydro-generator sets with a single capacity of 850,000 kilowatts are installed in the power station, with a total installed capacity of 654,330.

It is the first stage of four cascade hydropower stations (Wudongde, Baihetan, Xiluodu and Xiangjiaba) in the lower reaches of Jinsha River, and the fourth giant hydropower station in China and the seventh in the world to enter the ranks of 10 million kilowatts.

Its water retaining structure is a concrete hyperbolic arch dam with a crest elevation of 988m, a maximum dam height of 270m, a bottom thickness of 5 1m and a thickness-height ratio of only 0. 19. It is the thinnest 300-meter ultra-high arch dam in the world, and it is also the first ultra-high arch dam with low-heat cement concrete applied to the whole dam in the world.

Significance of Wudongde Dam Construction

Wudongde hydropower station is an important cascade project in river basin development, which has certain functions of flood control, shipping and sand interception. The construction of wudongde hydropower station is conducive to improving and giving full play to the downstream cascade benefits, and increasing the guaranteed output and power generation of downstream cascade power stations. The task of power station development is mainly to generate electricity, give consideration to flood control, promote local economic and social development and help immigrants get rid of poverty and become rich.

The six cascade hydropower stations on the main stream of the Yangtze River, namely Wudongde, Baihetan, Xiluodu, Xiangjiaba, Three Gorges and Gezhouba, constitute the largest "clean energy corridor" in the world. The total installed capacity of the six giant power stations is 71695,000 kilowatts, and a total of 1 10 hydropower units operate in coordination, generating electricity six times with a drop of water, with an average annual power generation of about 300 billion kwh, saving more than 90 million tons of standard coal and reducing carbon dioxide emissions by about 240 million tons each year.
