View DetailsThis marks the completion and operation of the largest grid-forming energy storage station in China. The photo shows the energy storage station supporting the Ningdong Composite Photovoltaic Base Project. This energy storage station is one of the first batch of projects supporting the 100 GW large-scale wind and photovoltaic bases nationwide.
On March 31, the second phase of the 100 MW/200 MWh energy storage station, a supporting project of the Ningxia Power's East NingxiaComposite Photovoltaic Base Project under CHN Energy, was successfully connected to the grid. This marks the completion and operation of the largest grid-forming energy storage station in China.
When fully charged, the upper reservoir can store enough energy to power the plant at full capacity for 10.8 hours, equivalent to nearly 40 GWh. This makes Fengning the most significant pumped storage facility in North China in terms of balancing renewable energy output.
China has emerged as a global leader in pumped storage technology, which is the most mature solution for large-scale, long-duration energy storage. By the end of 2024, the State Grid Corporation of China had 40.56 GW of operational pumped storage capacity, with an additional 53.48 GW under construction.
The Fengning Pumped Storage Power Station, the world's largest facility of its kind, has commenced full operations with the commissioning of its final variable-speed unit on December 31.
Located in Fengning County, Hebei Province, near Beijing and Tianjin, the plant is a key part of China's renewable energy infrastructure, supporting a nearby 10 GW wind and solar base in nearby Zhangjiakou.
