Northwestern China's Xinjiang autonomous region supplied 126.2 TWh of electricity to other places of the country in 2023, up slightly from a year earlier, according to data from the Xinjiang Power Exchange Center.
Since 2010, Xinjiang has cumulatively supplied 740.8 TWh of power across regions, enough to meet the demand of China's 1.4 billion population for 230 days. Producing this much power equates to burning 224.09 million tonnes of standard coal (7,000 Kcal/kg NAR), according to the center.
In 2020-2023, the outward renewable energy amounted to over 210 TWh, or nearly 30% of Xinjiang's total, it added. The clean power helped reduce carbon dioxide emissions by 171.52 million tonnes, sulfur dioxide by 0.54 million tonnes, and nitrogen dioxide by 0.47 million tonnes.
Ultra-high voltage transmission lines have played a significant role in Xinjiang's power transmissions.
The Hami-Zhengzhou ±800kV DC line transmitted 47.27 TWh in 2023, up 7.35% on the year. Since its commissioning, cumulative power deliveries along the line have reached 357.5 TWh, accounting for over 80% of Xinjiang's total outbound transmissions, and adding to 248.46 TWh since the project started operations.
Xinjiang boasts coal, wind and other energy advantages and is developing as a key comprehensive energy base for China. Its annual power transmissions have grown from 30 TWh in 2010 to 126.2 TWh last year, with the initial recipients of seven provinces expanding to 20 at present.
The existing power transmission network has built a total cross-regional transmission capacity of 25 GW in Xinjiang. Once another ±800kV DC line comes online, the capacity is set to increase to 33 GW.
