What are the hydropower stations under construction in China?

The Three Gorges Hydropower Station, namely the Yangtze Three Gorges Water Control Project, is also called the Three Gorges Project. The Xilingxia reach of the Yangtze River in Yichang City, Hubei Province, China, and the Gezhouba Hydropower Station in the lower reaches form a cascade hydropower station. The Three Gorges Hydropower Station is the largest hydropower station in the world and the largest construction project in China.

However, many problems caused by it, such as immigration, environment and so on, have been accompanied by great controversy since the moment it started construction. The Three Gorges Hydropower Station has more than ten functions such as shipping, power generation and planting.

2. Xiluodu Hydropower Station

Xiluodu Hydropower Station is the backbone project of the national "power transmission from west to east", which is located on the Jinsha River at the junction of Sichuan and Yunnan. The project mainly focuses on power generation, which has comprehensive benefits such as flood control, sand retention and improvement of upstream shipping conditions, and can provide cascade compensation for downstream power stations.

The power station mainly supplies power to East China and Central China, taking into account the power demand of Sichuan and Yunnan provinces. It is one of the backbone power sources closest to the "West-to-East Power Transmission" in Jinsha River and the largest hydropower station on Jinsha River. Its installed capacity is equivalent to that of Yitaipu Hydropower Station (140,000 kW), making it the second largest hydropower station in China and the third largest in the world.

3. Baihetan Hydropower Station

Baihetan Hydropower Station is located in ningnan county, Sichuan Province and Qiaojia County, Yunnan Province. This is the second cascade hydropower station developed in the lower reaches of Jinsha River. It has comprehensive benefits such as power generation, flood control, sand blocking, improving downstream shipping conditions and developing shipping in the reservoir area.

The normal water level of the reservoir is 825 meters, with a corresponding storage capacity of 20.6 billion cubic meters. The underground workshop is equipped with 16 units. The initial planned installed capacity is160,000 kilowatts, and the average power generation for many years is 60.24 billion kwh. The main project of the power station is planned to start in 20 13, the first batch of units will generate electricity in 20 18, and the project will be completed in 2022. After the power station is completed, it will become the second largest hydropower station in China after the Three Gorges Hydropower Station.

4. wudongde hydropower station

Wudongde hydropower station is located on the Jinsha River at the junction of Huidong County, Sichuan Province and Luquan County, Yunnan Province. It is the first of four water elevator stages downstream of Jinsha River Hydropower Base-Wudongde, Baihetan Hydropower Station, Xiluodu Hydropower Station, Xiangjiaba Hydropower Station, 253km above Guanyinyan Hydropower Station and 180km below Baihetan Hydropower Station.

The control basin area is 406 1 10,000 square kilometers, accounting for 86% of the Jinsha River basin area; The annual average flow is 3850 cubic meters per second, and the runoff120 billion cubic meters.

5. Xiangjiaba Hydropower Station

Xiangjiaba Hydropower Station is located in the lower reaches of Jinsha River at the junction of Shuifu County in Yunnan Province and Yibin County in Sichuan Province, only 1 1,500 m away from Shuifu County, and it is the last hydropower station in Jinsha River hydropower base. The hydropower station is built by Three Gorges Group, and it is 1.57km upstream of Xiluodu Hydropower Station. The river dam of the power station is a concrete gravity dam with the crest elevation of 384m and the maximum dam height of1.62m. ..

The dam site controls a drainage area of 458,800 square kilometers, accounting for 97% of the Jinsha River drainage area, with an average annual runoff of 38 10 cubic meter per second. The total storage capacity of the reservoir is 51630,000 cubic meters, the regulated storage capacity is 900 million cubic meters, and the backwater length is 156.6 kilometers.
