Sodium ion battery energy storage power stations are different from traditional power stations in that they not only achieve "peak power utilization", but also leverage the low-cost advantages of sodium ion batteries.

Sodium ion energy storage power stations store electricity during low electricity consumption periods and low grid electricity prices; During peak electricity usage and high electricity prices in the power grid, electricity storage is used. The basic mode of "peak power utilization" will save electricity costs. In addition, in the event of a sudden power outage in the power grid, it is also possible to switch to energy storage power stations in a timely manner to avoid losses caused by the outage.

On March 29, 2019, the world's first 100 kWh sodium ion battery energy storage power station was born and successfully supplied power to the Yangtze River Delta Research Center of the Institute of Physics of the Chinese Academy of Sciences, marking China's first demonstration operation of sodium ion battery energy storage power stations.

On June 28, 2021, the Institute of Physics of the Chinese Academy of Sciences and Zhongke Haina jointly launched the world's first 1MWh sodium ion battery optical storage and charging intelligent microgrid system in Taiyuan Comprehensive Reform Zone, Shanxi, and successfully put it into operation. The system uses sodium ion batteries as the main energy storage body, and combines with municipal power, photovoltaic, and charging facilities to form a microgrid system that can intelligently interact with the public power grid according to demand.
