金沙江白鹤滩水电站首批机组正式投产发电

6月28日上午，世界在建规模最大的水电站——白鹤滩水电站首批机组正式投产发电。

Baihetan Hydropower Station, located on the Jinsha River on the upper reaches of the Yangtze River, completed its concrete pouring on May 31, 2021. The first batch of generating units from the hydropower station, the world's second largest after China's Three Gorges Dam, went into operation on Monday morning. 

白鹤滩水电站位于四川省凉山彝族自治州宁南县和云南省昭通市巧家县境内的金沙江干流下游河段，是国家“西电东送”的重大工程。水电站装机总容量1600万千瓦，建成后是仅次于三峡电站的全球第二大水电站；单机容量100万千瓦，居全球第一；地下洞室群总里程217公里，规模全球第一。

白鹤滩水电站左右两岸分别装有8台百万千瓦水轮发电机组，均由中国企业自主研制。此次投产发电的机组为14号、1号机组。

The mega-project has a capacity of 16 million kilowatts and could generate more than 62 billion kilowatt-hours of electricity a year. Along with other power stations nearby, it helps to form the world's largest new energy corridor.

白鹤滩工程建设部技术管理副主任周孟夏表示，水电站建成投产后，年均发电量可达624.43亿千瓦时。在同等满足电力系统用电需求的情况下，每年可节约标准煤约1968万吨，减少排放二氧化碳约5160万吨，节能减排效益显著。

Zhou Mengxia, deputy director of the Technology Administration Office of Baihetan Engineering & Construction Department, said the hydropower that Baihetan provides will reduce the annual consumption of standard coal by 19.68 million tonnes and reduce carbon dioxide emissions by 51.6 million tonnes per year.

Chinese authorities said it aims to peak emissions by 2030, and become carbon neutral by 2060. To meet the goals, China's hydropower generation is expected to double, reaching 760 million kilowatts. That figure, according to Zhou, suggested that China's potential of developing clean energy still remains largely untapped.

Baihetan is also part of China's effort to transfer power generated in western regions to the east.

根据规划，白鹤滩水电站将于2022年7月实现全部机组投产发电，届时一天的发电量可满足50万人一年的生活用电。

全部投产发电后，白鹤滩水电站将与长江三峡、葛洲坝以及金沙江乌东德、溪洛渡、向家坝水电站一起，构成世界上最大的清洁能源走廊。
