The battery arrays approved by the China National Energy Administration will be made up of ten (10X) 20 MW / 80 MWh Vanadium Flow Battery (VFB) systems deployed on the Dalian peninsula, which during extreme weather events has experienced stress on the electricity grid. After full commissioning, the VFB battery will be able to peak-shave approximately 8% of Dalian's expected load in 2020. In addition, the large-scale battery will form an additional load center, which will enhance grid stabilization including securing the power supply and providing black-start capabilities in the event of emergency.
