The Number of Ultra-high Voltage Grid Construction Projects in Xinjiang to Reach a Record Level of 41 in 2025

On February 12, the State Grid Xinjiang Electric Power Company (the Company) revealed that by 2025, there will be 41 new and continued ultra-high voltage grid engineering projects in Xinjiang, an increase of 50 percent compared to 2024, setting a new historical record.

In 2024, the Company will manage 27 ultra-high voltage projects with a total line length of 5,044 kilometers and a power transformation capacity of 45 million kilovolt-amperes. Construction will commence on 16 projects, including the 750 kV Santanghu North and Naomao Lake Project. Meanwhile, five projects, such as the 750 kV Tacheng - Wusu and Bazhou - Tikanlik - Ruoqiang, will be completed and put into operation, setting a historical record for grid construction.

In 2025, the ultra-high voltage grids will continue to be upgraded in Xinjiang. According to the plan, there will be a total of 41 new and continued 750-kV transmission and transformation projects this year, with construction commencing in 20 new projects in Karamay, Ta'er, and other locations. These projects have a total line length of 1,818.7 kilometers and a power transformation capacity of 36 million kilovolt-amperes; for the 21 continued projects, the line length will reach 3,471.49 kilometers, with a power transformation capacity of 36 million kilovolt-amperes. There are also plans to put into operation 15 projects including the 750 kV Nanjing Huanta, Kuqa - Aral - Bachu, with a total line length of 2,622.09 kilometers and a power transformation capacity of 22.5 million kilovolt-amperes. The construction and operation scale of ultra-high voltage grid projects will reach the highest level in history, ushering in a new development stage characterized by "large scale, high intensity, and high quality."

As of now, Xinjiang's main grid has 31 750-kV substations with a total power transformation capacity of 90.5 million kilovolt-amperes and 92 lines totaling 12,705 kilometers, resulting in a main grid structure of "five internal supply rings and four external delivery channels." According to the plan, by the end of the 14th Five-Year Plan (2021-25), the Xinjiang grid will develop a main grid structure of "seven internal supply rings and five external delivery channels," which will provide a strong boost for converting Xinjiang's energy advantages into economic advantages.
