Staff members work at the main control room at the Barkol converter station, the sending end of the Hami-Chongqing ±800 kV ultra-high voltage direct current power transmission project, in Hami, northwest China's Xinjiang Uygur Autonomous Region, June 10, 2025.

Xinjiang is a key sending hub in China's west-to-east power transmission program.

Once considered economic obstacles, Xinjiang's vast deserts and arid landscapes have been transformed into a renewable energy goldmine, blessed with strong wind and long hours of sunshine.

Since 2010, Xinjiang has cumulatively transmitted over 900 billion kilowatt-hours of power outside the region, with renewable energy accounting for approximately 30 percent of the total. The electricity supply coverage extends to 22 provincial-level regions across China. (Xinhua/Ding Lei)
