Longtan

On the Hongshui River in China's Guangxi Zhuang Autonomous Region, the Longtan hydroelectric power station is located. It is an important part of China's West-East Electricity Transmission Project, which focuses on developing power resources in the western region and transferring electricity to the provinces of Jiangsu, Zhejiang, and Guangdong, as well as Shanghai, Beijing, and Tianjin, which are experiencing electricity shortages.

Longtan's 216.5-meter-high, 836-meter-long roller-compacted concrete (RCC) gravity dam has a 27.3-billion-cubic-meter water storage capacity and a 7-billion-cubic-meter flood control storage capacity. The power plant has a yearly capacity of 18.7 billion kilowatt-hours of electricity. The dam, power plant, and ship locks were all built as part of the project. In 2008, the plant's first phase, which had seven generators with a total capacity of 700 MW, became fully operational. In 2009, the ninth and last generator became fully operational.
