The "Eleventh Five-Year Plan of Renewable Energy Development" recently issued by Chinese Government has proposed to speed up the development of hydroelectric resource of Yalong River.Authorized by the National Development and Reform Commission,Ertan Hydropower Development Co.,Ltd.(EHDC) focuses on the construction of Jinping I,Jinping II,Guandi and Tongzilin power stations in lower reaches of the Yalong River and accelerating the design and site preparatory work in the middle reaches.In order to ensure on-schedule operation of the Jinping I,Jinping II and Guandi hydropower stations,EHDC initiated preparatory work for tendering procurement since 2004 and,with careful analysis,decided on a domestic base tendering strategy.By the end of 2007,all contracts of turbine-generator units for the three hydropower stations were signed.Due to the appropriate strategy,the tendering practice turned out some good results in that the buyer locked on the fabricating resources with reasonable prices and the domestic manufacturers got experiences of competition with their own technology of large hydro turbine-generator units in the future tendering,which exemplifies a socially profitable interactive development between market and domestic hydropower equipment manufacturing industry.
