Chain Hydropower Stations Fully Got Started
After 72-hour trial operation, Tianshengqiao first- and second-stage hydropower stations finally see their last two sets of power generators successfully got started. So far, the two large power stations, the first leg of China's west-east electricity transmission project, have been put into full operation.
Tianshengqiao first- and second-stage hydropower stations are built on the Hongshui River, astride the borders of Guangxi Zhuang Autonomous Region and Long'an County in Guizhou Province.
Tianshengqiao first-stage hydropower station, with construction began in 1991, started power generation in 1998. Operating with four sets of generators with an installed generating capacity of 1.2 million kilowatts and an annual power output of 5.2 billion kw/h, it has since had a total of 4 billion kw/h of power produced.
The second-stage station started construction in 1981 and began to be put into operation in 1992. Operating with 6 sets of power generators with an installed generating capacity of 13.2 million kilowatts and an annual power output of 8.2 billion kw/h, it has since had over 26.5 billion kw/h of electricity produced.
Built at a cost of over RMB$20 billion yuan, Tianshengqiao first- and second-stage hydropower stations are two key power suppliers on the long power chain of ten stage hydropower stations built on the Honghe River in China. For their karst locations and complicated geologic conditions on the Yunnan-Guizhou Plateau it is most extremely hard to have the two hydropower stations built in the area, said a responsible person in charge of the construction of the two power stations.
