Construction of main structure of China's highest-altitude UHV substation starts

(ECNS) -- The main part of the Ganzi 1000 kV ultra-high voltage substation officially commenced construction in Southwest China’s Sichuan Province, which is currently the highest-altitude ultra-high voltage substation under construction in China.

The substation will raise the altitude of China's ultra-high voltage substations from 1,500 meters to 3,450 meters.

After the project is completed, the main grid voltage of the Southwest China power grid will be raised from 500 kV to 1,000 kV, and it will transmit about 12 billion kilowatt-hours of clean electricity each year.
