Arizona-based Salt River Project is issuing an all-source request for proposals to seek additional power resources that can provide at least 200 MW during the summer peak to be online as early as May 1, 2026, and at least an additional 300 MW by May 1, 2027. 

To the extent the total capacity is not met by carbon-free options, SRP said it may procure up to an additional 500 MW of carbon-free resources. Doing so would hinge on the projects being feasible and cost effective, and if SRP can accommodate the additional resources.

Projects selected through the all-source RFP process are also expected to 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 more than 1,100 MW of battery storage systems. 

SRP said that this winter season it added a new utility-scale solar resource and announced two utility-scale battery storage projects slated to come online in 2024. Three solar-powered storage projects are slated to enter service this summer, including one of the largest solar-plus-storage facilities in the state, the Sonoran Energy Center.

SRP said it plans to cut its carbon dioxide emissions intensity by 65% by 2035 and by 90% by 2050 compared to 2005 levels. The utility said it plans to host a web conference for respondents on March 20, and is requesting bid proposals by April 27. A short-list selection is expected by this fall.
