Governor Inslee and UET CEO Z. Gary Yang
Washington State is now home to the world’s largest containerized flow battery system. The Snohomish County Public Utility District (SnoPUD) launched a 2.2 MW / 8 MWh battery system on March 28 as part of the Washington State Clean Energy Fund. The celebration was hosted by UniEnergy Technologies, who developed and manufactured the vanadium flow battery systems in Mukilteo, Washington. Doosan GridTech (formerly 1Energy Systems), Pacific Northwest National Laboratory (PNNL) and the Washington State Department of Commerce partnered on the project.
SnoPUD deployed two battery storage systems as part of the Clean Energy Fund in an effort to improve energy reliability and renewable energy integration across the Pacific Northwest. The first 2 MW battery system was installed in 2014. The second 2.2 MW peak power battery system from UET is now operational. Both systems include management software designed by Doosan GridTech.
The UET batteries and control systems are housed in 20 shipping containers, each 20 feet in length. By capacity, the system is the world’s largest containerized vanadium flow battery storage system.
The SnoPUD deployment with UET and Doosan GridTech illustrates why Washington State is quickly emerging as an energy storage hub. The vanadium flow chemistry used in UET batteries was invented at PNNL in Richland, developed and manufactured by UET in Mukilteo, and deployed by SnoPUD in Everett. Doosan GridTech is also a Seattle-based company working to transform the global industry with standards-based management software.
The SnoPUD energy storage projects were made possible in part by a $7.3 million investment from the Washington State Clean Energy Fund. Since 2013, the Washington Legislature has appropriated $76 million for the state’s Clean Energy Fund to help strengthen communities all across the state by developing new businesses and jobs.
“This is not a time to be humble” said Governor Jay Inslee about the Clean Energy Fund project. “These big batteries mean big jobs right here in Washington State.”
CleanTech Alliance recently identified more than 87,500 direct and 165,000 indirect clean technology jobs in Washington State, along with hundreds of thousands more throughout the greater Northwest region. The Clean Energy Fund is driving our economy forward while creating a more resilient energy grid.
