Arizona public power utility Salt River Project (SRP) has issued a request for proposals (RFP) for additional power generation resources of all types to meet summer peak capacity needs. 

SRP on Oct. 29 said that it continues to experience significant increases in customer electricity demand as Phoenix and Maricopa County lead the nation in population growth and economic development. 

SRP is seeking competitive proposals for up to 400 megawatts (MW) of peak generating capacity by summer 2024, and another 600 MW by summer 2026, for a total up to 1,000 MW by summer of 2026. 

Resources selected through this all-source RFP process will also support SRP’s 2035 Sustainability Goals and SRP’s goal to add 2,025MW of new utility-scale solar by 2025. 

The requested generation is needed in addition to SRP’s recently announced contracts for new renewable resources and plans to expand its Coolidge Generating Station.  

SRP said it will consider all technologies and currently serves customer energy needs from generation produced with a diverse fuel mix including nuclear, coal, hydroelectric, natural gas, battery storage and renewable resources including solar, wind, biomass, and geothermal. 

This summer SRP announced agreements for four new utility-scale solar plants, as well as the commissioning of Arizona’s largest standalone battery storage system which began operating on SRP’s system this September. 

Respondents to the all-source RFP can view the details and register here: srp.net/all-source-rfp. Registration enables access to all RFP-related documents.

SRP is seeking bid proposals by Jan. 11, 2022 and anticipates short list selection in April 2022.
