The Highest-Voltage Power Transmission Project Worldwide Surpasses 300 Billion Kilowatt-Hours of Electricity Delivery

As of 0:00 on October 8, the Changji-Guquan ±1100 kV UHVDC transmission project (Changji-Guquan DC) has cumulatively delivered 302.15 billion kilowatt-hours (kWh) of electricity, surpassing the 300 billion kWh milestone. This amount is equivalent to the conversion of 120.86 million tons of standard coal locally and has led to a reduction of 301.2435 million tons of CO₂ emissions. In this year alone, the project has transmitted 53.68 billion kWh of electricity, reflecting a 9.1 percent increase compared to the same period last year.

The Changji-Guquan DC project

The Changji-Guquan DC is the world's highest voltage, largest capacity, and longest-distance UHV power transmission project, spanning 3,293 kilometers. It serves as a crucial energy channel for China's west-to-east power transmission program, playing a significant role in converting Xinjiang's resource advantages into economic benefits and ensuring energy supply security in China.

Employees checking the operation of the project

To ensure the safe and stable operation of the project, the State Grid Xinjiang Electric Power Co., Ltd. has developed specialized monitoring standards based on the project's operation. It consistently conducts daily comparisons, weekly analyses, and monthly summaries of various monitoring data to identify and manage defects and hidden risks early. This includes using an integrated monitoring system, high-definition industrial video surveillance with eagle-eye networks, fully automated transformer inspection systems, smart inspection robots and drones, and automatic infrared thermal analysis systems for valve halls. Additionally, the company utilizes big data algorithms to analyze equipment operation status and provide fault warnings, significantly improving equipment safety and health. (Text/Photo by Chen Kai, Qin Xiu)
