Jinping 1 Hydropower Station (Jinping 1st cascade or Jinping No.1 hydraulic power station) is a large water power project at the Yalong (Yalong Jjiang), in SCN. It is currently under construction.
Purpose
The project's objective is to supply energy for expanding industrialization and urbanization, improve flood protection, and prevent erosion.
Location
The Jinping power station is on the border of the Yanyuan and Muli districts in the autonomous Liangshan Yi area of the SCN province. The Yalong river, which the dam will control is the largest tributary of the Jinsha. For the project, approximately 7,500 inhabitants will be relocated.
Design
The main structure will be a 300 m high elbow rope wall, to which a 3600-Megawatt Kraftwerk will be attached. It will become the highest or one of the two highest dams on earth, since the Rogun dam, 335 m in height, is not yet built. Thyssenkrupp supplied a cableway for the building site.
Power Generation
The power station will have six turbines, each capable of producing 600 megawatts, for a total of 3600 megawatts. The annual production of Jinping I is estimated to be between 16 and 18TWh (billion KW/H).
Schedule
Construction work began on November 12 2005. Expectations are that power first will be generated in 2012 with the remainder of the work completed by 2014.
System
It is one of the many large-scale Chinese water power projects, which at present are at the construction or planning phases. The best-known of these is the Three Gorges Dam. Twelve of these power stations together are to supply 22,850 MW into the grid. (the 18,200 MW of the Three Gorges Dam are not contained in this figure.) The Ertan dam, which will provide 3300 MW, is already finished.
Future Projects
The Jinping II project will follow, with a generating capacity of 4700 megawatts.
