SRP Issues Request for Proposal for Non-Inverter Based Long Duration Energy Storage
SRP’s service territory is experiencing record growth, with SRP’s Integrated System Plan predicting the need to double or triple the amount of generating resources by 2035. The majority of SRP’s service territory includes large portions of Maricopa County, which is one of the fastest growing counties in the nation according to the U.S. Census Bureau. This significant growth, increasing interest from large customers in serving their energy needs with carbon-free resources, and SRP’s commitment to reducing carbon intensity are collectively driving a need to add significant carbon free resources to SRP’s generation portfolio. SRP aims to reduce its carbon intensity by 82% by 2035 relative to a 2005 baseline and reach net-zero carbon emissions by 2050. To reach these goals, SRP plans to significantly increase its solar and battery energy storage capacity. SRP is also interested in exploring alternatives to lithium-ion battery storage.
To continue providing reliable and renewable power to customers and meet 2035 and 2050 goals, SRP requests proposals for a non-inverter based long-duration energy storage (LDES) pilot facility with a capacity of 5-50 megawatts (MW) and duration of 10 hours. SRP proposes siting of the pilot at its coal-fired Coronado Generating Station (CGS) in St. John’s, Arizona, which is scheduled to be decommissioned in 2032. This RFP is part of SRP’s work to explore other resources to repurpose the site.

To continue providing reliable and renewable power to customers and meet 2035 and 2050 goals, SRP request proposals for a non-lithium-ion inverter based long duration energy storage (LDES) pilot facility with a capacity of 5 megawatts (MW) and a duration of 10 hours. The resource will be located at the Copper Crossing Energy and Research Center in Florence, Arizona, which will also host CMBlu Energy's “Desert Blume”, a 5 MW, 10-hour LDES project.
