at about 11:00 on June 16, the last unit of the Wudongde Hydropower Station on the Jinsha River, the seventh largest hydropower station in the world and the fourth largest hydropower station in China, successfully completed the 72 hour trial operation and was successfully incorporated into Nanfang power and officially put into operation for power generation. So far, Wudongde Hydropower Station has achieved the goal of putting all 12 850000 kW units into operation and power generation on schedule

Wudongde Hydropower Station is located on the Jinsha River at the junction of Luquan County, Kunming City, Yunnan Province and Huidong County, Liangshan Prefecture, Sichuan Province. It is the top level of the four cascade hydropower stations in the lower reaches of the Jinsha River developed and constructed by China Three Gorges Corporation. The development task is mainly power generation, taking into account flood control, shipping and promoting local economic and social development

the total storage capacity of the hydropower station reservoir is 7.408 billion cubic meters, with seasonal regulation capacity and obvious flood control benefits. Six hydraulic turbine generator units with a single unit capacity of 850000 kW are arranged on the left and right banks of the power station, which is the largest hydraulic turbine generator unit in the world that has been put into operation under too high or too low pressure. The power station has the functions of fire prevention, thermal insulation and decoration. The total installed capacity is 10.2 million KW, and the annual average power generation is 38.91 billion kwh, which is equivalent to saving 12.2 million tons of standard coal and reducing 30.5 million tons of carbon dioxide emissions every year

the construction of Wudongde Hydropower Station was officially approved on December 16, 2015, and the first batch of units were put into operation on June 29, 2020. Wudongde Hydropower Station has been fully completed and put into operation, creating eight world-class firsts, including the world's thinnest 300 meter super high arch dam, and 15 global firsts, including the use of low heat cement concrete for the whole dam. It has made breakthroughs in eight hydropower projects, including flood control, during the construction period, and has overcome a series of world-class problems, such as temperature control and crack prevention of mass concrete, excavation of super large-scale underground caverns, and welding of 80 0 MPa high-strength steel with two backup rollers, The "double zero" goal of quality and safety has been achieved for many consecutive years, setting a new benchmark for the construction of hydropower projects in the world

the clean hydropower produced by Wudongde Hydropower Station is directly transmitted to Guangdong Hong Kong Macao Great Bay area through Nanfang power. As of June 16, Wudongde Hydropower Station has delivered more than 24 billion kwh of clean Hydropower to Guangdong, Hong Kong, Macao, Dawan district and other places, which can support the industrial power consumption of Guangzhou for nearly seven months, replace the combustion of about 7.52 million tons of standard coal, reduce about 18.81 million tons of carbon dioxide and 63000 tons of sulfur dioxide (calculated according to the industrial power consumption of Guangzhou in 2020)

"as the centenary of the party is approaching, it is of great significance that Wudongde Hydropower Station is fully completed and put into operation in the first year of the 14th five year plan." Lei Mingshan, chairman of the Three Gorges group, said that the construction of the power station will provide important support for achieving the goals of carbon peak and carbon neutralization, building a clean, low-carbon, safe and efficient energy system, and inject strong momentum into the comprehensive green transformation of economic and social development

what "halos"

300 meter super high arch dam is the thinnest in the world

the river retaining arch dam of Wudongde Hydropower Station is 270 meters high, equivalent to 96 stories high, and it is also the thinnest 300 meter super high arch dam in the world. The dam bottom is 51.41 meters thick, and the thinnest part of the dam is only 11.98 meters

the excavation height of the underground powerhouse ranks first in the world

the main powerhouse of the underground powerhouse on the left and right banks of Wudongde Hydropower Station is 333 meters long, the arch span is 32.5 meters, and the height is 89.8 meters, ranking first in the world

hydro generator rotor is the heaviest in the world

the total installed capacity of Wudongde Hydropower Station ranks seventh in the world and fourth in China. A total of 12 hydropower units with a unit capacity of 850000 kW are installed, which is second only to Baihetan Hydropower Station in the world. Among them, the rotor of hydro generator weighs 2100 tons, which is equivalent to the weight of 1400 ordinary family cars, and is the heaviest in the world

the total storage capacity is equivalent to 518 West Lakes

the total storage capacity of Wudongde Hydropower Station reaches 7.408 billion cubic meters, equivalent to 518 West Lakes. The maximum flood discharge can reach 37362 cubic meters per second, and the whole west lake can be filled in 7 minutes

What "dividends"

power generation: help the construction of Guangdong Hong Kong Macao Greater Bay Area

after the completion of Wudongde Hydropower Station, clean hydropower will help the construction of Guangdong Hong Kong Macao Greater Bay area and other places. According to the data, in 2019, the total electricity consumption in Guangzhou was about 100.5 billion kwh. According to this calculation, the annual power generation of Wudongde Hydropower Station can meet the power demand of Guangzhou for nearly five months

flood control: reduce the amount of water entering the Three Gorges Reservoir

during the flood season, Wudongde reservoir can reduce the amount of water entering the Three Gorges Reservoir by storing the Jinsha River flood. Ke Dongjie told that cooperating with the operation of the Three Gorges reservoir can further improve the flood control standard of the Jingjiang River section and reduce the flood volume caused by disasters in the middle and lower reaches of the Yangtze River; Cooperating with Baihetan, Xiluodu and Xiangjiaba reservoirs in the lower reaches of Jinsha River will further improve the flood control capacity of Yibin, Luzhou, Chongqing and other regions in the Chuanjiang River

benefiting the people: being the "engine" of economic and social development

the completion and operation of Wudongde Hydropower Station can transform the advantages of hydropower resources in the West into economic advantages, which is of great significance to the construction of the Yangtze River economic belt, the coordinated development of regional economy, and the implementation of the western development strategy in the new era

according to statistics, after all units of Wudongde Hydropower Station are put into operation, it can contribute about 11.9 billion yuan of industrial added value every year, increasing local fiscal revenue by 1.35 billion yuan; Sichuan and Yunnan provinces, which hold some shares in the power station, can also share stable income every year
