Strategic arteries, completed and put into operation!

The reporter learned from the State Grid that it was completed and put into operation on July 1st on July 1st. This is the strategic artery of China's "Western Power East Transmission" project on July 1st. This is the strategic arteries of my country's "Western Power East Transmission" project.

On June 15th, at the 500 -kilovolt Yucheng Stream Station to the Yushan line engineering site, the construction staff of Jiangsu Province Delivery Co., Ltd. was set up a wire at more than 130 meters.

Xin Baoan, chairman of the State Grid, said that the Baihetan -Jiangsu Project spans Sichuan, Chongqing, Hubei, Anhui, Jiangsu, 5 provinces and cities, with a total length of 2080 kilometers. Major green engineering and service technology independence and self -reliance. The total investment of the project is 30.7 billion yuan, which has driven the development of the upstream and downstream industrial chain. It will effectively serve the development and utilization of Southwest Hydropower, ensure the safe and reliable supply of electricity in Jiangsu, and promote the coordinated development of regional economy.

"The Baihe Beach -Jiangsu Project is the world's first hybrid link -level joint high -voltage DC transmission project." The deputy director of the National Power Grid Special High -voltage Ministry said that the project has developed the "conventional DC+flexible DC" hybrid joint -level joint jointly in the world UHV DC transmission technology, integrated high -voltage DC transmission large capacity, long -distance, low loss, and the advantages of flexible DC transmission control and strong system support capabilities, demonstration leading is significant.

"West East Transmission" is a major strategy for my country's energy development, which will promote the large -scale development and delivery of Sichuan hydropower. As of the end of 2021, Sichuan hydropower installed capacity reached 89.47 million kilowatts, and the installed capacity of hydropower and annual power generation ranked first in the country. The Baihetan Hydropower Station is located in the dry flow section of the Jinsha River. The installed capacity is 16 million kilowatts. The installed capacity is second only to the Three Gorges Power Station. It is planned to be completed and put into operation in 2022. Among them, 8 million kilowatts of units were built on the left and right banks, and Dian Jiangsu and Zhejiang were sent. After the completion of the Baihetan -Jiangsu project, it can effectively guarantee the large -scale delivery of the Baihetan Hydropower Station, promote the transformation of Sichuan resources to the economic advantage, and help the western economy rise.

Wu Wei, deputy director of the Construction Department of the State Grid Jiangsu Electric Power Company, said that the economy of East China is developed, with large number of electricity bases, high proportion, strategic emerging industries, new formats and new models, and new formats will accelerate development. Baihe Beach -Jiangsu's engineering transmission capacity reaches 8 million kilowatts, which can meet the needs of the economic and social development of Jiangsu.

After the completion of the Baihetan -Jiangsu project, it can promote the reduction of 14 million tons of coal used in East China each year and more than 2,500 million tons of carbon dioxide.
