Energy storage power station for large factories

What is the Fengning pumped storage power station?

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.

Why is Fengning the most significant pumped storage facility in North 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.

Is China a leader in pumped storage technology?

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.
