On May 16, 2026, in the underground factory building of Guangning County, Zhaoqing, a stator with a height of 5.8 meters and a weight of about 380 tons was accurately positioned, marking the official start of the installation of China's first domestically produced variable speed unit. Zheng Zhi from Nanwang Energy Storage introduced that the unit can adjust the speed by ± 7%, achieve real-time adjustment of 50% power, and can store 280000 cubic meters of water per hour. Keywords: electricity, power station

Compared to fixed speed units, variable speed units can flexibly respond to grid demand and efficiently absorb new energy. This installation promotes the independent and controllable development of variable speed pumped storage technology in China, enhances the power grid regulation capability, and provides support for the construction of new power systems.
