Today (the 22nd), the world’s largest hybrid pumped-storage power station under construction—Sichuan Yalongjiang Lianghekou Pumped Storage Power Station—reached a critical milestone with dual breakthroughs: the excavation of the underground powerhouse is complete, and concrete pouring has begun at the downstream reservoir.

At an altitude of 3,000 meters on the western Sichuan Plateau, over a thousand builders worked tirelessly during the Spring Festival, seizing the “golden window” of the dry season to accelerate construction. Core projects such as underground caverns and water diversion tunnels are progressing steadily.

This high-altitude green energy “supercharger” is rapidly taking shape, providing vital support for China’s clean energy supply and grid regulation.
