ESS Tech, Inc. (NYSE: GWH) (ESS, or the Company), a leading manufacturer of long-duration energy storage (LDES) systems for commercial and utility-scale today applications, today announced a collaboration framework with Salt River Project (SRP) and Google for Project New Horizon to advance long-duration energy storage innovation at SRP's Copper Crossing Energy and Research Center in Florence, Arizona.

Project New Horizon is a five-megawatt (MW), 50 megawatt hour (MWh) system that will deploy ESS' iron flow Energy Base technology and represents a significant commercial validation milestone for the Company's next-generation, utility-scale platform. The pilot is expected to support SRP's evaluation of emerging non-lithium LDES technologies and, if successfully executed, could help unlock follow-on commercial opportunities with utilities and large energy users seeking scalable, LDES solutions.
