Google joins 5MW/50MWh iron flow storage pilot in Arizona
Google partners with ESS Tech and Salt River Project to deploy a five-megawatt, 50-megawatt-hour iron flow Energy Base system at SRP’s Copper Crossing Energy and Research Center in Florence, Arizona. The pilot will validate ESS Tech’s utility-scale, non-lithium long-duration storage platform for future renewable integration.
1. Project Collaboration Framework
ESS Tech has established a collaboration framework with Salt River Project and Google for Project New Horizon, located at SRP’s Copper Crossing Energy and Research Center in Florence, Arizona.
2. System Capacity and Technology
The pilot features a five-megawatt power output paired with 50 megawatt-hours of storage, deploying ESS Tech’s iron flow Energy Base non-lithium platform designed for long-duration utility-scale applications.
3. Strategic Implications for Google
This initiative provides Google with a testing ground for emerging energy storage technology, advancing its renewable integration targets and enhancing grid reliability at a key Arizona site.
