The reporter learned from the Three Gorges Corporation on the 20th that the last unit of Baihetan Hydropower Station, the world's most technically difficult hydropower station with the largest single unit capacity and the second largest installed capacity, successfully completed the 72 hour test run and was officially put into operation for power generation. So far, the 16 million kilowatt hydroelectric generating units of Baihetan Hydropower Station have all been put into operation, which marks that China has built the world's largest "clean energy corridor" on the Yangtze River.

(The picture is provided by the Three Gorges Group) The Three Gorges Group has built and operated six giant cascade hydropower stations in the mainstream of the Yangtze River - Wudongde, Baihetan, Xiluodu, Xiangjiaba, Three Gorges and Gezhouba. Through the joint operation of these six giant hydropower stations, the average annual power generation can reach 300 billion kWh, the standard coal can be saved about 90.45 million tons each year, and the carbon dioxide emissions can be reduced about 248.4 million tons, forming the world's largest "clean energy corridor". This corridor spans 1800 kilometers, forming a cascade reservoir group with a total storage capacity of 91.9 billion cubic meters and a strategic fresh water resource reservoir, of which the flood control storage capacity is 37.6 billion cubic meters, accounting for more than 53% of the total flood control storage capacity of the reservoirs included in the joint operation scope of the Yangtze River basin in 2022. It is of great significance for ensuring flood control, power generation, shipping, water resource utilization and ecological security of the Yangtze River basin. Lei Mingshan, Chairman of the Three Gorges Group and Secretary of the Party Leadership Group, said that Baihetan Hydropower Station is a large-scale hydropower project that has been under construction since the 18th National Congress of the Communist Party of China and has been fully completed since the 20th National Congress of the Communist Party of China. The project adopts all domestic water turbine generator units with the largest single unit capacity of one million kilowatts in the world, achieving a major breakthrough in high-end equipment manufacturing in China. The operation of Baihetan Hydropower Station is of great significance to the adjustment of China's energy structure, the construction of the Yangtze River Economic Belt, and the coordinated development of regional economy. The dam site of Baihetan Hydropower Station is located at the lower reaches of the main stream of Jinsha River in Ningnan County, Sichuan Province and Qiaojia County, Yunnan Province. Baihetan Hydropower Station has a huge scale and complex geological conditions. Its construction has created six world firsts, including the single unit capacity of a million kilowatt hydro generator, the seismic fortification index of a 300 meter high arch dam, and the scale of underground caverns.
