Shanghai UHV project has transmitted 4.2 billion kilowatt hours of electricity to Shanghai

According to a statement issued by the State Grid Corporation of China on October 19, as of October 16th, the Xiangjiaba-Shanghai ±800 kV UHVDC transmission demonstration project has been put into operation since it was put into operation. 4.2 billion kWh has been transmitted, and the average daily transmission is 2 million kWh. . As of October 14th, through the Xiangjiaba-Shanghai UHV project, Sichuan's hydropower transmission has reached 17.64 billion kwh this year, an increase of 51.18% year-on-year; it is estimated that Sichuan Electric Power will deliver an annual total of approximately 19 billion kwh, making Sichuan During the “Eleventh Five-Year Plan” period, the accumulated electricity delivered by the power grid reached 62.5 billion kwh.

The Xiang-UHV UHVDC transmission demonstration project was approved by the state on April 26, 2007. It has a total length of 1,907 kilometers and a total dynamic investment of 23.274 billion yuan. It was successfully put into operation on July 8 this year and is the highest voltage level in the world. The DC transmission project with the largest transmission capacity and the longest transmission distance.

After the project is put into operation, it can deliver 32 billion kwh of clean electric energy to Shanghai each year. The maximum transmission power accounts for about one-third of Shanghai's peak load, which can save 15 million tons of raw coal and reduce carbon dioxide emissions by more than 30 million tons.
