Total electricity delivered from Xinjiang surpasses 800 billion kilowatt-hours

Shiliuyun-Xinjiang Daily (Reporter Chen Qiangwei) news: As informed by the Xinjiang Power Trading Center Co., Ltd. on July 7, 2024, since the initiation of the Xinjiang power transmission project in 2010, as of July 5th this year, a total of 801.4 billion kilowatt-hours of electricity has been transmitted from Xinjiang to cover 20 provinces and regions across China. This highlights the increasingly prominent role of Xinjiang as a comprehensive energy base.

According to calculations, the electricity delivered through delivery services amounts to 801.4 billion kilowatt-hours, which is sufficient to meet the energy needs of China's entire population of 1.4 billion people for a period of 249 days. Notably, renewable energy accounts for over 230 billion kilowatt-hours, representing nearly one-third of the total electricity delivered. In other words, approximately one unit out of every three units sent from Xinjiang is derived from green sources. These sustainable power sources effectively reduce coal combustion by 69.57 million tons and mitigate carbon dioxide emissions by 188 million tons, sulfur dioxide emissions by 590 thousand tons, as well as nitrogen oxide emissions by 510 thousand tons.

As of July 4, Xinjiang's cumulative installed capacity for new energy has soared to an impressive 79.801 million kilowatts, encompassing 37.763 million kilowatts from wind power and 42.038 million kilowatts from photovoltaic power—constituting nearly half of Xinjiang's total installed capacity. The scale of new energy installation in Xinjiang not only ranks first in northwest China but also stands among the top nationwide.

The current infrastructure in Xinjiang includes 28 substations operating at a voltage of 750 kV, with transmission lines spanning a total length of 10,300 kilometers. Xinjiang has emerged as the leading province in China's provincial power grid, boasting the highest number of 750 kV substations, the longest transmission lines at this voltage level, and the largest coverage area. This remarkable achievement facilitates effective utilization of wind and solar resources across different regions within Xinjiang throughout various times of day and seasons while significantly enhancing resource allocation efficiency.

In terms of out-of-Xinjiang transmission, Xinjiang Electric has achieved a capacity of 25 million kilowatts, expanding its coverage from initially 7 provinces and municipalities to 20 provinces and municipalities. The amount of electricity transmitted has increased significantly from 300 million kilowatt-hours in 2010 to an impressive 126.2 billion kilowatt-hours in 2023. From the period between 2018 and 2023, both Xinjiang Electric's out-of-Xinjiang electricity volume and new energy have experienced substantial growth rates at an average annual rate of approximately 20% and18%, respectively. Starting from the year 2020, the out-of-Xinjiang electricity volume has consistently exceeded one hundred billion kilowatt-hours for four consecutive years.

The construction of the fifth ultra-high voltage transmission channel in Xinjiang - Hami-Chongqing ±800 kV UHVDC transmission project is currently being expedited, with an expected completion and operation date set for 2025. By then, Xinjiang's power export capacity will reach 33 million kilowatts, while the proportion of clean energy exports to total exports will increase from nearly 30% to 50%.
