The Baishan Dam ({{zh|s=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 {{convert|1500|MW}} while it can also control a design {{Convert|19100|m3/s|ft3/s}} flood. Additionally, it has a {{convert|300|MW}} pumped-storage hydroelectric generation capacity. It is named after Baekdu Mountain (White Mountain), near the city of Baishan.
Construction
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.{{cite web|title=Hydropower Stations in Northeast China |url=http://www.chinaembassy.org.in/eng/szyss/jm/zhongguonongye/Water%20Conservancy/t144248.htm|publisher=Embassy China|accessdate=9 January 2011|date=2004-07-29}} The dam submerged an area of {{Convert|17.67|km2|sqmi}}, displacing about 10,300 people.{{cite web|title=Baishan Hydropower Station |url=http://www.waterpub.com.cn/JHDB/DetailDam.asp?ID=12 |publisher=Water Pub |accessdate=9 January 2011 |language=Chinese |url-status=dead |archiveurl=https://web.archive.org/web/20120314044154/http://www.waterpub.com.cn/JHDB/DetailDam.asp?ID=12 |archivedate=14 March 2012 }}
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.{{cite web|title=吉林白山抽水蓄能电站顺利通过验收 (Jilin Baishan Pumped Storage Power Station passed acceptance) |url=http://news.bjx.com.cn/html/20080527/125843.shtml|publisher=Polaris Power News Center |accessdate=9 January 2011|language=Chinese|date=May 27, 2008}}
Design
The Baishan Dam is a {{Convert|149.5|m}} tall and {{Convert|677.5|m}} long arch gravity dam composed of {{Convert|1663000|m3}} of concrete.{{cite web| title= Dams Overview| url= http://www.geokon.com/projects/dams.php| publisher= Geokon, Inc.| accessdate= 9 January 2011| archiveurl= https://web.archive.org/web/20101201063539/http://geokon.com/projects/dams.php| archivedate= 1 December 2010| url-status= dead}} It withholds a {{Convert|6500000000|m3|acre.ft}} reservoir of which {{Convert|3540000000|m3|acre.ft}} is active or "useful" storage and {{Convert|950000000|m3|acre.ft}} is flood storage. The dam's spillway contains four {{Convert|12|x|13|m}} openings and three {{Convert|6|x|7|m}} mid-level openings on its orifice. All the dam's openings can discharge a design of {{Convert|19100|m3/s}}, check standard of {{Convert|26200|m3/s}} and maximum of {{Convert|32200|m3/s}} of water.
The dam powers three separate power stations. The first station to be constructed is located underground and contains 3 x 300 MW Francis turbine generators while the second, located on the left bank slightly downstream contains 2 x 300 MW Francis turbine generators. The third portion of the dam's power station is 2 x 150 MW pump-generators. The dam's current reservoir serves as the upper and the Hongshi Dam's reservoir downstream serves as the lower.
