Three utility scale energy storage systems using vanadium flow and lithium-ion technology totalling 4MW are being installed in America’s Pacific Northwest region.
Three different utility companies were given a total of $14.3 million—which they had to match with their own funding— by Washington state’s Clean Energy Fund to install the storage systems.
Snohomish County Public Utility District in Everett, Washington, plans to install UniEnergy Technologies’ 2.2 MW/h system. A 1MW lithium-ion substation has already been installed in the district to be integrated with renewable sources for peak shifting.
Utility firm Avista Corp has started testing a 1 MW-3.2 MW/h battery storage system in the city of Spokane.
A third utility, Puget Sound Energy, is installing a 2 MW-4.4 MW/h lithium-ion battery system to provide back-up power to its substation in Glacier, a small town in the foothills of stare’s Baker Mountain.
