由于电力严重匮乏,前苏联政府决定利用伏尔加河和卡马河的水电资源修建大型水电站,以保证在最短的时期内供电。然而由于各方面的原因,致使前苏联水电蕴藏量只被利用了36%时即已停止开发,直至20世纪80年代,才重新开始对水力资源的开发。而此时欧洲部分国家的水电资源已开发了90%以上,美国、加拿大等国也已开发了50%～65%,但俄罗斯却只开发了不到其总数的7%。在完成了大量勘测、研究工作之后,拟定了几十个水电站坝址,以开发伏尔加河流域的水电资源。一批拟建的水电站主要位于山麓河流,水库淹没的土地非常少,这些新水电站的修建,将使其水电资源的开发增加至46.3%,技术上可开发的蕴藏量的开发增加至72%,水电资源的经济效益将达到93.3%。
Due to the severe lack of electricity, the former Soviet government decided to use the hydroelectric resources of the Volga and Kama rivers to build large hydropower stations in order to ensure the power supply in the shortest period of time. However, due to various reasons, the hydroelectric power reserves in the former Soviet Union had been shut down only when they were utilized by 36%. Until the 1980s, the development of hydropower resources was resumed. At this time, hydropower resources in some European countries have been developed over 90%, while the United States and Canada have also developed 50% to 65%. However, Russia has only developed less than 7% of the total. After a large number of surveys and studies were completed, dozens of hydroelectric dam sites were drafted to develop hydropower resources in the Volga Basin. A number of proposed hydropower stations are mainly located in the foothills of rivers and reservoirs. There are very few land submerged in these reservoirs. The construction of these new hydropower stations will increase the development of hydropower resources to 46.3% and the development of technologically developable reserves to 72% The economic benefits of hydropower resources will reach 93.3%.
