Ertan Hydropower Station
Ertan - The largest hydropower station completed in China in 20th century
- The largest flood discharge capacity in the existed high arch dams in the world
- The third highest dam in existed double curvature arch dams in the world
Ertan Hydropower Station is Located in Panzhihua City of Sichuan Province, and is the first stage project in cascade power developments on lower reach of Yalong River. It is a huge hydropower project with main purpose for power generation, the total installed capacity of Ertan is 3300MW and with a 240m thin double curvature arch dam. Many engineering characteristics are among the best worldwide. Construction preparation of Ertan began in 1987, main project construction started in 1991 and the first unit was put into operation in 1998. The whole project was completed in 2001. Since the astonishing achievement of Ertan, Chengdu Engineering Corporation Limited obtained Gold Awards of both Engineering Investigation and Engineering Design in China.
Jinping I Hydropower Station
Jinping I - The highest arch dam under construction in the world
- Control reservoir for lower reach of yalong river
Jinping I Hydropower Station is located at Yanyuan County and Muli County in Sichuan Province and has a control reservoir for lower reach of Yalong River. The main purpose of the project is power generation with other functions of flood and sedimentation control. The total installed capacity of Jinping I is 3600MW and with a concrete arch dam of 305m in height, which is the highest arch dam in the world. The annual operation hours of units are 4836h and annual output is 17410GWh. This project is the high quality power supply for “West-east power transmission” in China.
