The Baishan Dam (Chinese: 白山大坝, meaning: "White Mountain Dam") is an arch-gravity dam on the Second Songhua River near the town of Baishanzhen, Huadian, Jilin Province, China. The purpose of the dam is hydroelectric power generation and flood control. The dam supplies water to five turbine-generators in two different powerhouses for an installed capacity of 1,500 megawatts (2,000,000 hp) while it can also control a design 19,100-cubic-metre-per-second (670,000 cu ft/s) flood. Additionally, it has a 300-megawatt (400,000 hp) pumped-storage hydroelectric generation capacity. It is named after Baekdu Mountain (White Mountain), near the city of Baishan.
Construction on the dam began in May 1975, the reservoir began to fill on September 16, 1982, and by the end of 1984, the first phase of three generators was operational. Another two generators in the project's second phase were operational by 1992.[1] The dam submerged an area of 17.67 square kilometres (6.82 sq mi), displacing about 10,300 people.[2]
In March 2000, a feasibility study report on a pumped-storage capability for the dam was approved. In August 2002, construction started on installing two 150 MW reversible pump generators and by July 2006, they were operational.[3]
