一、加快开发中型水电站的必要性与迫切性四川持续缺电已达十五年之久,近几年电力供需的矛盾更趋严重。 1985年,全省水、火电装机462.64万千瓦,其中水电244.9万千瓦。年发、购电量236.94亿度,其中水电125.81亿度(包括向西北、贵州购电17.02亿度)。四川人口与粮食产量约各占全国的十分之一,而年发电量和工农业产值仅占全国的二十分之一左右,极不相称。 I. Necessity and urgency of accelerating the development of medium-sized hydropower stations Sichuan has been in short supply for 15 years. In recent years, the contradiction between power supply and demand has become more serious. In 1985, the province’s installed capacity of water and thermal power was 4,626.4 kilowatts, of which 2.449 million kilowatts of hydropower. In the year, the electricity purchase amounted to 23.694 billion kWh, of which 12.581 billion kWh (including the purchase of 1.702 billion kWh to the northwest and Guizhou). Sichuan’s population and grain output each account for approximately one-tenth of the country’s total. The annual output of electricity and industrial and agricultural output accounts for only about one-twentieth of the country’s total output, which is extremely disproportionate.
