Longtan Hydropower Station is a backbone project in cascade development of the Hongshuihe River, with a total installed capacity of 6,300MW, total reservoir capacity of 27.3billion and flood storage capacity of 7billion and normal poll level of 400m. With dam height of 216.5m, Longtan dam is the highest RCC gravity dam with the largest underground powerhouse, vertical shiplift of maxi lifting height and largest air-cooling turbo-generator units in the world.

The Longtan reservoir began collecting water from Hongshui River in the summer of 2006. On September 30, 2006, the four sluice gates lowered to stop the flow of the river and the Longtan reservoir began storing the collected water. The reservoir is capable of holding 35 billion cubic yards (27 billion m3) of water. Power generation began in May 2007, two months ahead of schedule. A total of three generators went into operation in 2007. Nearly four years after the first batch of concrete was poured in August 2004, completion of the dam superstructure was announced four months ahead of schedule on March 12, 2008. Approximately 9.57 million cubic yards (7.36 million m3) of concrete were poured into the main wall of the dam. The final six generators are supposed to be installed and operational in 2009. The entire project is estimated for completion in December 2009.

It was designed to provide power generation, help flood control, improve conditions for shipping, and combat salt tide that has plagued water usage in cities along the Pearl River Delta. The entire project involves the construction of a roller-compacted concrete gravity dam, subterranean power plant, and two ship locks to allow for navigation past the dam. The project is estimated for completion in 2009 and the projected cost is US$4.2 billion (30 billion yuan).

Twenty percent of the project is being funded by governmental organizations, forming Longtan Hydropower Development Co. The other 80 percent is being provided by loans from China Development Bank, China Construction Bank, Bank of China and Agricultural Bank of China.

The completed dam will be the world’s highest roller-compacted dam at 710 feet (216.5 m) high and 2,729 feet (832 m) wide. The underground power plant will be 1,274.3 feet (388.5 m) long, 934.8 feet (285 m) wide, and 238.5 feet (72.7 m) high. The hydropower station will be equipped with nine generators, with a total installed power capacity of 5,400 megawatts, which is expected to produce between 15.6 to 18.7 billion kilowatt-hours annually. The ship locks and lifts will be the world’s fastest, capable of lifting major cargo ships 587 feet (179 m) from the river level below to the reservoir level behind the dam.

The Longtan Hydropower Station requires the relocation of more than 80,000 residents in 10 counties of Guizhou Province and Guangxi.
