The battery arrays approved by the China National Energy Administration will be made up of ten (10X) 20MW/80MWh Vanadium Flow Battery (VFB) energy storage systems deployed in Dalian city and connected to the main grid of Liaoning Province which has experienced stress during extreme weather events. After full commissioning, the VFB energy storage system will be able to peak-shave approximately 8% of Liaoning Province's expected peaking capacity 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.

This project will be deployed in two phases, each with 100MW/400MWh. The first phase will be finished around the end of 2017 and the second will be finished around the end of 2018. This project is approved by China National Energy Administration, and the owner is a JV with the major shareholder being a local utility company, and the minor being RONGKE POWER.
