The Pacific Northwest National Laboratory is working with three utilities who were awarded $14.3 million in grants Tuesday as part of the state’s new Clean Energy Fund.
Gov. Jay Inslee announced the grants for Avista Corp., Puget Sound Energy and Snohomish PUD that are designed to help them better integrate power from intermittent renewable sources like wind and solar into the electrical grid.
The announcement was made at UniEnergy Technologies’ Mukilteo facility with Pat Hoffman, assistant secretary for the U.S. Department of Energy.
PNNL researchers in Richland developed advanced batteries made with “redox flow” technology to store large amounts of renewable energy and provide greater stability to the energy grid.
PNNL will provide analytical and technical support for all three projects, according to a PNNL news release.
PNNL will work with Spokane-based Avista, which received $3.2 million, on developing a control strategy for a UniEnergy flow battery at Washington State University Pullman. The project will support WSU’s smart campus operations.
Puget Sound Energy, which received $3.8 million, will install a lithium ion battery. PNNL analyzed the costs and benefits of installing energy storage as part of a previous project with the utility.
Snohomish PUD, which is receiving $7.3 million, is installing a UniEnergy flow battery and a lithium ion battery.
