At the heart of this landmark project is a hybrid energy storage system integrating vanadium flow batteries (VFBs) with lithium iron phosphate (LFP) batteries—demonstrating the growing strategic importance of vanadium flow battery technology in large-scale, grid-support applications. The Gushanliang 300MW / 1200MWh grid-forming hybrid energy storage power station in Ordos, Inner Mongolia, supplied by Sineng Electric, has successfully completed full “three-charge, three-discharge” commissioning tests and has officially entered commercial operation.
