World's highest UHVDC transmission project completes final line installation

The world's highest ultra-high voltage direct current (UHVDC) transmission project, from the upper reaches of Jinsha River to central China's Hubei Province, had its final line installation completed on Tuesday, achieving full-line connectivity, according to the State Grid Corporation of China.

Around 14:00 Tuesday, in Yajiang County, Garze Tibetan Autonomous Prefecture, southwest China's Sichuan Province, the last two transmission conductors of the project were installed successfully, marking that the entire project was fully connected.

"The most challenging section of the project was the one in western Sichuan, which traverses the western Sichuan plateau and Hengduan Mountains, with the highest tower position at nearly 4,800 meters above sea level. Completion of the line installation today means we have successfully tackled the final 'tough nut.' Next, we will accelerate testing and debugging of the converter stations and lines to make the final push for the project's full completion and operation," said Liu Bo, project manager of the western Sichuan section of the project.

The project will connect hydropower and new energy from the upper reaches of Jinsha River to the ultra-high voltage alternating current backbone grid in central China.

The line spans 1,901 kilometers across Xizang Autonomous Region, Sichuan, Chongqing Municipality, and Hubei.

Once completed, it will become China's first large-capacity, water-solar hybrid clean energy transmission corridor, capable of delivering 40 billion kilowatt-hours of electricity annually.
