China's Hami-Zhengzhou ±800 kV ultra-high voltage direct current (UHVDC) transmission line has achieved a milestone, transmitting over 10,000 gigawatt-hours (GWh) of electricity this year as of March 16 – an 11.2% year-on-year surge. This engineering marvel, stretching 2,192 km across six provinces and autonomous regions, is fueling sustainable energy goals while bridging economic development between Xinjiang and central China.
Operational since 2014, the project channels abundant wind and solar power from Hami, located at the base of the Tianshan Mountains, to power-hungry Henan Province. The region's renewable resources are now lighting homes and powering factories over 1,300 miles away, demonstrating China's growing capacity for long-distance clean energy distribution.
Analysts highlight dual benefits: central China gains stable electricity for its industrial heartland, while Xinjiang unlocks economic potential through infrastructure-driven growth. The line has become a critical artery in China's energy transition strategy, combining technological innovation with cross-regional cooperation.
