Arizona electrical utility Salt River Project (SRP) and Google-backed long-duration storage company Energy Dome have announced plans to deploy a 19MW, ten-hour CO2-based long-duration energy storage system (LDES) at SRP's Coronado Generating Station in St. Johns, Arizona.
Google will co-fund a portion of the project.

The system will operate under a 20-year tolling agreement, in which Energy Dome will own and operate the facility, and SRP will dispatch its output. The system is expected to be operational sometime in 2029. EPRI, the independent energy research institute, will monitor performance data from the project.
"As energy demand continues to grow, SRP is evaluating new energy storage technologies that could support SRP's effort to diversify its battery energy storage portfolio as we work to meet the Valley's growing energy needs with affordable, reliable, and sustainable power," said Chico Hunter, SRP manager of innovation and development.
