China Launches Ultra-High Voltage Power Transmission Project from Xinjiang to Chongqing

The State Grid Corporation of China announced the commencement of operations for the ±800 kV ultra-high voltage direct current transmission project. This project connects Hami in eastern Xinjiang with Chongqing municipality in Southwest China.

This marks the third significant project in China dedicated to transmitting electricity from the energy-rich Xinjiang Uygur autonomous region to other regions of the country. The transmission line stretches over 2,260 kilometers.

The project is supported by a substantial installed power capacity of 14.2 million kilowatts. A significant portion of this capacity, 10.2 million kilowatts, comes from renewable sources including wind, solar photovoltaic, and solar thermal energy. New energy sources constitute over 70 percent of the total capacity.

Xinjiang plays a crucial role as a major hub in China's west-to-east power transmission initiative. The new transmission line is projected to deliver over 36 billion kilowatt-hours of electricity annually to Chongqing's power load center. This will significantly bolster the municipality's energy supply capabilities.

The project is also anticipated to contribute to economic growth in both Xinjiang and Chongqing. It is expected to foster regional coordinated development, support rural revitalization efforts, and improve public welfare.

The State Grid Corporation of China currently operates the world's largest ultra-high-voltage transmission network. This network provides crucial support for ensuring a secure and dependable power supply while promoting green and low-carbon development.
