en.Wedoany.com Reported - On June 6, the first top arch layer of the underground powerhouse at Qinghai Warang Pumped Storage Power Station, the largest pumped storage power station under construction in western China, officially commenced construction. This marks the entry of this giant "energy heart" rooted in the Qinghai-Tibet Plateau into the main phase of cavern construction, reaching a significant milestone in underground powerhouse construction and ushering the project into a new stage of development.

It is reported that the underground powerhouse serves as the key energy conversion hub of the power station, primarily responsible for unit installation and energy storage and power generation. "Once the power station is operational, it will optimize the power source structure of the northwest power grid, efficiently absorb new energy sources such as wind and solar power, and accumulate valuable high-altitude construction experience for pumped storage projects in the Yellow River Basin," said Li Haifeng, Chairman of Qinghai Warang Pumped Storage Power Station. The station can pump water for energy storage during low electricity demand periods and release water for power generation during peak demand, achieving peak shaving and valley filling of the power grid. It also offers functions such as frequency and phase modulation, emergency standby, and black start. The first unit is expected to be commissioned by 2030, with full completion by 2031.
