【Inner Mongolia Kezhen 2.5MW/10MWh Sodium-Ion Energy Storage System Project Connected to Grid】Recently, the 2.5MW/10MWh sodium-ion energy storage system project in Kezhen, Wuchuan County, Hohhot City, Inner Mongolia Autonomous Region, built by XuDa Renewable Energy, was successfully connected to the grid. This project represents the first grid-side sodium-ion energy storage system in Inner Mongolia, with an installed capacity of 2.5MW/10MWh. During the construction of the project, XuDa Renewable Energy adopted a string-type sodium-ion energy storage system, which can be flexibly configured according to different application scenarios and needs, adapting to various scales of energy storage projects. Whether it is for small-scale distributed energy storage or large-scale grid-side energy storage, the string-type system can effectively meet the requirements. This system boasts high reliability. By designing the energy storage units in a string configuration, independent management and monitoring of each unit can be achieved, enhancing the system's stability.
