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 districts Yanyuan and Muli in the autonomous area Liangshan Yi of the province SCN. The Yalong river, where the dam is located, is very water-rich and the largest tributary of the Jinsha. For the project 7479 inhabitants must be resettled.
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.
Generation Power
The power station will have six sets of turbines with 600 MW each, together generating 3600 MW. The annual production of Jinping I Estimated to be 16,62 or 18,2 TWh (billion KW/H).
Schedule
The construction work began the November 12 2005.It is expected that in 2012 the first power will be generated and the remainder of the work will be 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 project Jinping II is to follow later; it will have a 4700 MW capacity.
