China launches world’s ‘smartest’ mega hydropower station (PHOTOS, VIDEOS)
The first power-generating unit of the Wudongde Hydropower Station in China has been successfully put into operation on Monday. Wudongde is the world’s seventh-biggest hydroelectric power plant, and the fourth largest in China.
The launch ceremony was attended by Chinese President Xi Jinping.
Dubbed the ‘smartest’ hydropower station in the world, it is located on the border of the Sichuan and Yunnan provinces in southwest China. The station has been constructed using cutting-edge intelligent technologies, including real-time temperature monitoring and advanced grouting equipment.
Thermometers and cooling pipes have been embedded in the concrete to detect its temperature in real time. The water flow can be automatically adjusted to realize the cooling process of concrete in an intelligent way.

Wudongde is the first dam in the world to fully use low-heat cement that can withstand large temperature differences. The temperature difference, which causes the cracking of concrete and threatens the safety of the dam, is a worldwide problem in hydropower engineering.
Wudongde was designed as a concrete double-curved arch dam with a maximum height of 270 meters. The foundation bed of the dam is only 51 meters thick, which makes the hydropower station the thinnest 300-meter arch dam in the world at present. The “thin” concrete will be able to afford a storage of approximately 7.4 billion cubic meters of water in its reservoir.
At 11:25 a.m. on June 29, the first two units of Wudongde Hydropower Station successfully completed a 72-hour trial operation and were successfully connected to the grid! #hydropower #sustainability #cleanenergy pic.twitter.com/kpuzQyjvEK

The excavation length of the main workshop of the underground power station in Wudongde dam broke the world record with a height of 89.8 meters, equivalent to a 30-story building.
The hydropower station will be able to generate 38.9 billion kilowatts of electricity annually after its 12 generating units start operation. The project is scheduled to be fully completed in December 2021.
The amount of hydropower produced by Wudongde will save 12.2 million tons of standard coal and reduce emissions of carbon dioxide and sulfur dioxide by 30.5 million tons and 104,000 tons every year.

Together with Baihetan Hydropower Station, Xiluodu Hydropower Station and Xiangjiaba Hydropower Station, Wudongde will form part of a cascade of power stations on the Jinsha River. The cluster will have an installed capacity of more than 46 million kilowatts and will generate about 190 billion kilowatt-hours of electricity annually.
