UniEnergy Technologies (UET) has announced the commissioning and acceptance of a 1MW Uni.System™ advanced vanadium redox energy storage system.
The 4MWh system in Pullman, Washington, will be the largest capacity flow battery operating in North America and Europe, according to the company.
Avista Utilities will use the system for load shifting, frequency regulation, and conservation voltage regulation on the Turner distribution circuit.
It will also support Avista’s end-user, manufacturer Schweitzer Engineering Laboratories with UPS, black start, and 4-cycle ride-through.
The project is funded in part by the Washington State Clean Energy Fund. Over $14 million in matching grants were awarded to Avista, Puget Sound Energy, and Snohomish Public Utility District for projects to demonstrate battery technologies in the electrical grid.
