Arizona public power utility Salt River Project has issued an all-source request for proposals in which it seeks additional power resources that can provide at least 200 megawatts during the summer peak to be online as early as May 1, 2026, and at least an additional 300 MW by May 1, 2027.

SRP will evaluate and compare proposals that meet the minimum requirements identified in the RFP, including SRP self-developed resource options. SRP currently serves customer energy needs with a diverse fuel mix including nuclear, coal, hydroelectric, natural gas, battery storage and renewable resources including solar, wind, biomass, and geothermal.

To the extent the total requested capacity SRP is seeking is not satisfied by carbon-free resource proposals, SRP may procure up to an additional 500 MW of carbon-free resources. This is contingent on the projects being feasible, cost effective, and if SRP can accommodate these additional resources while maintaining customer reliability.

Resource projects selected through the all-source RFP process will also support SRP’s 2035 sustainability goals by adding to new renewable-resource and storage system projects SRP has under contract and expects to have online by 2025. These include 2,025 MW of added solar resources, 161 MW of wind energy, and over 1,100 MW of battery storage systems. SRP has among the largest utility-scale renewable and battery storage investments in the Western U.S.

Respondents to the all-source RFP can view the details and register here: http://srpnet.com/AllSourceRFP. Registration enables access to all RFP-related documents.

SRP will offer a web conference for respondents on March 20, 2023 and is requesting bid proposals by April 27, 2023. SRP anticipates short-list selection by Fall 2023.
