今年二月中国人民建设银行投资研究所在“重新评价水电的经济性”一文中提出:水电比火电投资高一倍,工期长一倍,设备利用小时打六折,又有一个很大的重复容量损失……而且,水电要远距离输送,其相关投资要比火电的煤、运投资大很多,在计算资金的时间价值后,水电成本也比火电高,并不“廉价”。因此,搞水电划不来,西部黄河上游水电富矿的开发也不值得。总之,得出我国水电的经济性不高的结论。
In February of this year, the Investment Research Institute of the People’s Construction Bank of China stated in the article “Re-evaluate the economical efficiency of hydropower” that hydropower is twice as expensive as thermal power, twice as long as the construction period, and the installation hours are 40%, and there is a big one. Loss of capacity... Moreover, hydropower needs to be transported over long distances, and its related investment is much larger than coal and transportation investment of thermal power. After calculating the time value of capital, the cost of water and electricity is also higher than thermal power, and it is not “cheap”. Therefore, it is not worthwhile to develop hydropower resources in the upper reaches of the Yellow River in the west. In short, the conclusion that China’s hydropower economy is not high is drawn.
