Investment and Operation of Hydropower

SPIC has the qualifications for development and EPC contracting of hydropower projects. On the basis of addressing resettlement and ecological protection properly, and following China’s hydropower development principle of “river basin,cascade, rolling and integrated development”, SPIC carries forward the development and construction of cascade hydropower plants (HPPs) on the upper reaches of the Yellow River and the Yuanshui River drainage basin in Hunan in an orderly fashion and has successfully built two cascade hydropower clean energy bases in the above two regions.

SPIC has 144 HPPs in operation with a total installed capacity of 21596.7MW, distributed in 12 provinces including Qinghai, Hunan, Yunnan, Guizhou, Guangxi, Sichuan, etc. 1,000 MW and larger HPPs that have been put into commercial operation include Longyangxia HPP, Laxiwa HPP, Lijiaxia HPP, Gongboxia HPP, Jishixia HPP, Wuqiangxi HPP and Sanbanxi HPP. Twelve hydropower stations are under construction with a total installed capacity of 910.5 MW.

Apart from developing hydropower in China, SPIC plans to develop seven cascade HPPs and a construction power station (Chipwi Nge HPP) on the upper reaches of the Ayeyawady River, Myanmar, with a total installed capacity of 21.6 GW and an average annual power generation of 114 TWh.

Representative projects
 
Laxiwa HPP

The second large-scale cascade HPP on the section from Longyangxia to Qingtongxia of the upper reaches of the Yellow River. The single unit capacity is 700 MW and the total installed capacity is 3,500 MW. In 2010, all five units were put into operation with average annual power generation of 10.2 TWh. The HPP has a concrete double-curved arch dam with the maximum dam height of 250 m and the total reservoir capacity of 1.1 billion m 3 . It has the highest dam,largest capacity and power generation in the north of China.

 
 
Longyangxia HPP

It is the large-scale hydropower project designed and built by China independently,representing the highest level of China’s hydropower engineering in the 1980s. The single unit capacity is 320 MW and the total installed capacity is 1,280 MW; the average annual power generation is 6 TWh.

 
Changzhou HPP

Located in the Pearl River Basin, due to its large scale and capacity, and large number of units, it is named as “world-class HPP with tubular turbines” by industry experts. It crosses two islands and three rivers, and is installed with 15 bulb type tubular turbines with a single unit capacity of 42 MW. Thirteen protection and drainage pumping stations were built in the reservoir area and two supporting substations were built.

 
 
Wuqiangxi HPP

It is the largest HPP in Hunan Province, with a single unit capacity of 240 MW and a total installed capacity of 1,200 MW. Its main function is to generate electricity, supplemented by flood control, navigation and other purposes.
