On January 20, construction officially commenced on the Guangdong section of the ±800kV ultra-high voltage (UHV) direct current (DC) transmission project from southeastern Xizang to the Guangdong-Hong Kong-Macao Greater Bay Area. The project was surveyed and designed by GEDI.

This project is a key inter-provincial power transmission initiative under China's 14th Five-Year Plan. It stands as the world's largest UHV multi-terminal flexible DC transmission project by capacity and features the longest UHV flexible DC transmission line globally. The transmission line starts in southeastern Xizang and ends in the Guangdong-Hong Kong-Macao Greater Bay Area, spanning four provinces and regions: Xizang, Yunnan, Guangxi, and Guangdong. The project boasts a transmission capacity of 10 GW. GEDI undertakes the survey and design of a ±800kV flexible DC converter station, a deep well grounding electrode, approximately 415.6 kilometers of DC lines, and 87 kilometers of grounding electrode lines in the Guangdong section of the project.

The Guangdong section passes through coastal regions vulnerable to strong winds and extends through the cities of Guangzhou, Dongguan, and Shenzhen. This corridor is characterized by a highly developed economy and dense population, with infrastructure such as railways, expressways, and transmission lines crossing the area. The GEDI design team meticulously organize and plan the project, adopting a comprehensive approach that encompasses environmental protection, social impact, construction challenges, and project investment. They conduct thorough preliminary planning and route selection, leveraging the internally developed "Drive Future CAD" digital platform for overhead line design to precisely simulate and optimize the route. These efforts ensure that construction commence on schedule and meet the highest standards of quality.
