200MW/800MWh Energy Storage Station to be Built with RONGKE POWER’s Vanadium Flow Battery

DALIAN, CHINA — The China National Energy Administration has approved the world’s largest energy storage station to be built in Dalian, China. Rongke Power will supply its Vanadium Flow Batteries (VFB’s) for the 200-Megawatt, 800-Megawatt-hour (200MW/ 800MWh) station. The energy storage station will provide peak-shaving as well as form another load center for the Dalian peninsula, enhancing grid stabilization.

For the Dalian project, the China National Energy Administration performed several rounds of due diligence. Rongke Power’s vanadium flow battery was selected due to its advantages including reliability, full recyclability of the electrolyte, and more than 20 year life-time. These advantages had been proved in multiple Megawatt-class energy storage systems already built by Rongke Power to support wind farms in Liaoning province, where Dalian is located.

The 200MW/800MWh energy storage station is aimed to tackle peak-shaving challenges in the south area of Dalian, where the existing grid can be strained under extreme weather conditions. After full commissioning, the new VFB energy storage station will be able to peak-shave approximately 8% of Dalian’s expected load in 2020. In addition, the large-scale station will form an additional load center, which will enhance grid stabilization including securing the power supply and black-start capabilities in the event of emergency. The integration of intermittent renewable energy is also anticipated, potentially in conjunction with other energy storage projects.

This project will accelerate Rongke Power’s mass production of its leading VFB’s and yield priceless further expertise on large-scale battery energy storage deployment.

About UET
UET manufactures its breakthrough MW-scale containerized advanced vanadium flow battery products in a 60,000 square foot manufacturing facility near Seattle, Washington. Prior to launching UET in 2012, its founders led the core technology development at Pacific Northwest National Laboratory in Washington State for 5 years with U.S. DOE Office of Electricity funding. The technology safely delivers the smallest bulk energy footprint in the industry with unlimited cycle life over 20 years. UET now has almost 20MW/80MWh of energy storage systems deployed, ordered, or awarded. Reference customers include the utility, microgrid, and commercial & industrial sectors.
