The "Electricity from Xinjiang to Chongqing" ultra-high voltage project has transported more than 40 billion kilowatt-hours of electricity in total.

China News Service, Urumqi, September 30 (Yan Wenlu Reporter Jiang Jing learned from the State Grid Xinjiang Electric Power Co., Ltd. on the 30th that the ±800 kV Hami-Chongqing UHV DC transmission project (referred to as the "Xinjiang Power to Chongqing" project) has transported more than 40 billion kilowatt-hours of electricity, continuously delivering clean electricity from deserts, Gobis, and deserts to Bashan and Chongqing, injecting strong green momentum into Chongqing's livelihood security, industrial stability, and digital industry development.

The "Xinjiang Electric Power Transfer to Chongqing" project is one of the 102 major projects in the country's "14th Five-Year Plan". It is my country's first UHV DC project to be sent to the Shagehuang New Energy Base, and it is also the first UHV receiving channel in Southwest China. The total investment in the project is 28.6 billion yuan. The line starts from Barkol Converter Station in Hami, Xinjiang in the west, and ends at Yubei Converter Station in Chongqing in the east. It passes through five provinces and cities in Xinjiang, Gansu, Shaanxi, Sichuan, and Chongqing. It has a total length of 2,260 kilometers, a rated transmission capacity of 8 million kilowatts, and a designed annual power transmission of over 36 billion kilowatt hours. After the project is completed and put into operation, it will open up the inter-regional power distribution channel between the northwest clean energy base and the Chengdu-Chongqing load center, build an ultra-high voltage power corridor directly connecting the northwest to the southwest, and further optimize the national energy resource allocation pattern.

According to reports, the "Xinjiang Electricity to Chongqing" project has a supporting power supply installed capacity of 14.2 million kilowatts, adopting the "wind, solar, thermal storage" multi-energy complementary integration model, of which wind power, photovoltaic, and solar thermal new energy have an installed capacity of 10.2 million kilowatts, accounting for 71.8%. It can deliver more than 18 billion kilowatt hours of green power every year, effectively easing the pressure on local consumption of new energy in Xinjiang. According to estimates, these green electricity can help Chongqing reduce coal consumption by 6 million tons and reduce carbon dioxide emissions by 16.5 million tons every year, which is equivalent to the carbon reduction of planting 900 million trees. The ecological benefits are significant.

In the next step, State Grid Xinjiang Electric Power will continue to strengthen equipment operation and maintenance management and control, maintain the bottom line of safe production, and ensure the smooth operation of this energy artery spanning more than 2,000 kilometers, so that more Xinjiang green power can serve the country's "dual carbon" construction and energy security.
