Public Requests for Proposals (RFP)

2023 All-Source RFP

SRP’s service territory continues to experience significant growth. This continued projected growth, combined with potential challenges with new resource development, planned coal retirements and ongoing Colorado River drought conditions, creates a need for additional power generation resources to ensure that SRP can maintain reliable electric service beginning in the summer of 2026. Accordingly, SRP is issuing this All-Source Request for Proposals (2023 ASRFP) to seek additional resources that can provide at least 200 megawatts (MW) at the summer peak to be online as early as May 1, 2026, and a minimum of an additional 300 MW by May 1, 2027, subject to load forecasts.

SRP also seeks to add up to 500 MW of new carbon-free resources. To the extent that 500 MW of carbon-free energy is not satisfied by the selected proposals for peak capacity, SRP may procure additional carbon-free resources if projects are determined to be feasible and cost-effective and SRP determines it can accommodate these additional resources while maintaining customer reliability.

SRP will also be developing a proposal for flexible natural gas units to be located at a site to be selected in the coming months. SRP’s analysis of the pricing and information submitted in response to its 2021 All-Source RFP suggest that flexible natural gas units represent the most cost-effective resource that will provide the necessary reliability and maintain SRP’s path to meeting our sustainability goals. SRP also recognizes that the market is changing and evolving quickly and that the passage of the Inflation Reduction Act provides an opportunity to consider other resource alternatives. SRP is issuing this ASRFP to seek cost-effective alternatives to the flexible natural gas proposal that it will be developing. SRP expects to present the top-scoring resource options and a recommendation to its Board of Directors in late 2023.
