It is about 100 kilometres (62 mi) northeast of Lhasa, in Maizhokunggar County. It is at an elevation of 12,660 feet (3,860 m) above sea level, downstream from the 160 MW Pangduo Hydro Power Station at 13,390 feet (4,080 m). The Zhikong Dam, a rock-fill dam, is 50 metres (160 ft) tall. It impounds 225,000,000 cubic metres (7.9×109 cu ft) of water. The plant has four 25 MW Francis turbines supplied by Kunming, and is operated by the China Huaneng Group. Installed capacity is 100 MW and annual production is about 407 GWh. The reservoir is also used for flood control and irrigation.
Construction
The Lhasa River Zhi Kong hydroelectric power station was a key project of the tenth five-year plan. Construction began in May 2003, with the No 8 Hydroelectricity Corp of the Armed Police Force responsible for engineering, procurement, and construction. After a fiasco with the Yamdrok Hydropower Station in 1996, 120 kilometres (75 mi) south of Lhasa, the deputy commander of the People's Armed Police construction brigade was placed in charge of the project. Construction cost 1.37 billion yuan. The first generator was commissioned in 2006 and the power station was put into full operation on 23 September 2007.
