On June 10, the Hami–Chongqing ±800kV UHVDC transmission project, designed in part by GEDI, commenced full operation and began delivering electricity.

This project represents China's first UHVDC transmission endeavor dedicated to exporting power from desert, gobi, and remote new energy bases. Furthermore, it serves as the third "Xinjiang power transmission" DC channel. Originating from the Barkol Converter Station in Hami, Xinjiang, the project spans through the provinces of Gansu, Shaanxi, and Sichuan, culminating at the Yubei Converter Station in Chongqing. It employs the "Double 800" UHVDC transmission technology, featuring a rated voltage of ±800 kV and an operational capacity of 8 million kilowatts, with a transmission range of 2,260 kilometers.

GEDI contributed to the design of the AC yard, AC filter yard, station front area, and auxiliary operational facilities of the Barkol Converter Station at the transmission end of the project. Additionally, GEDI conducted survey and design activities involving large equipment transport, off-site facilities and grounding electrode lines. The project team effectively integrated the standardized technical achievements of the "Double 800" UHV converter station. Considering the challenging conditions at the station site, such as strong winds, extreme cold, sand and dust, and saline soil, the team conducted comprehensive optimization in areas including wind resistance, sand prevention, antifreeze, and corrosion protection. These efforts ensure the safe and reliable operation of equipment while maintaining the continuity and stability of power transmission. Additionally, given the Hami region's extremely cold winters, extended winter breaks, and brief construction periods, extensive adoption of prefabricated technical solutions significantly reduced on-site wet operations, enhanced construction efficiency, and facilitated favorable conditions for UHV project development in these harsh environments.
