1981年全国水电完成发电量638亿度,比计划多发138亿度,超计划27.6%,比1980年增加56亿度。这是我国水电历史上最好的一年,标志着我国水电运行管理水平又有了新的提高。638亿度占全国总发电量20.9%,相当于替代燃煤3,826万吨,这对减轻煤炭、石油能源消耗,起了重要的作用。 In 1981, the nation’s hydropower generated 63.8 billion kWh of electricity, an increase of 13.8 billion kWh from the plan, an over- plan of 27.6%, and an increase of 5.6 billion kWh from 1980. This is the best year in the history of hydropower in China and it indicates that the level of hydropower operation management in China has also been improved. The 63.8 billion kilowatt-hours accounted for 20.9% of the country’s total electricity generation, equivalent to the substitution of 38.26 million tons of coal, which played an important role in reducing the consumption of coal and petroleum energy.
