Jinping I is a large hydropower project that has been producing electricity since 2013 on Yalong Jiang in Sichuan in southwest China . It is also referred to as Jinping 1st cascade or Jinping No.1 Hydropower Station. The dam is also used for flood protection and the retention of sediments .

The project aims to deliver energy from the economically weaker west to the densely populated east of China . The Jinping-power plant located on the border between the county Yanyuan and the Autonomous County Muli of the Tibetan Autonomous County in Liangshan of Yi in Sichuan Province. The Yalong is the largest tributary of the Jinsha and very rich in water.

The main structure is a 300 m high arch dam to which a 3600 megawatt power plant is connected. Another source gives the height of the dam wall at 305 m. In both cases, it is the highest or one of the two highest dams on earth, as the Rogun Dam with a height of 335 m has not yet been completed. The so far leading Nurek dam is also 300 m high.

The completed power plant will have six machine sets with 600  MW each, a total of 3600 MW. It is a major Chinese hydropower project, of which the Three Gorges Project is the best known. Twelve of these power plants together are expected to deliver 22,850 MW. (The 18,200 MW of the Three Gorges project are apparently not included in this.) The Ertan Dam, also with 3300 MW, is already finished. The Jinping II project will follow later; it will have another 4700 MW capacity. The annual electricity production of Jinping I is given as 16.62 or 18.2 TWh (billion kWh).

Construction work began on November 12, 2005. It was originally expected that the first electricity could be generated in 2012 and that the remaining work will be completed by 2016. The Thyssen company supplied a cable crane for the construction site.
