The State Grid Corporation of China has announced the launch of a large-scale energy project. The new ±800 kV ultra-high voltage direct current transmission line will connect Hami city in the Xinjiang Uygur Autonomous Region with Chongqing.

The project represents the third major initiative to transport electricity from the energy-rich Xinjiang region to other parts of the country. The new transmission line will span 2,260 kilometers with an installed capacity of 14.2 million kilowatts.

A key feature of the project is its high share of renewable energy sources — more than 70% of the total capacity comes from wind, solar, and solar thermal energy, amounting to 10.2 million kilowatts.

According to specialists' calculations, the new line will supply over 36 billion kilowatt-hours of electricity annually to Chongqing's power grid, significantly strengthening the municipality's energy security.
The corporation notes that the project should stimulate economic development in both regions, promote coordinated inter-regional development, and improve living standards for the population, including rural areas.

The State Grid Corporation of China currently operates the world's largest ultra-high voltage power transmission network, which serves as an important element in ensuring energy stability and developing a low-carbon economy in the country.
