All Source RFP
APS requests renewable energy resources of approximately 300-400 megawatts (MW) per year which will increase the amount of clean energy on the APS system. The RFP also is designed to address peak capacity needs of about 200-300 MW per year to maintain reliable electric service for customers during times of highest energy usage. Procuring more renewable energy supports an interim target within APS’s clean energy commitment: to have 45% of its generation portfolio in renewables by 2030. This RFP is open to all technologies, including supply side and non-supply side resources. Proposed projects must have in-service dates in either 2023 or 2024.
Battery Energy Storage RFP
APS requests a combined total of 60 MW of battery storage additions to two of its existing AZ Sun Project solar facilities: the Red Rock and Chino Valley plants located in Pinal County and Yavapai County, respectively. Proposed projects must begin delivery no later than June 1, 2023.
The RFP process will be monitored and reviewed by a third-party independent monitor. The All Source RFP, Battery Energy Storage RFP and important information about proposal requirements and respondent registration are available at aps.com/rfp
Added Battery Capacity to AZ Sun Sites
Battery energy storage systems will be developed and installed by Invenergy at six of APS’s existing large-scale solar power plants and will begin operation in early 2022. Since announcing these plans last year, APS has now executed the agreement after working with Invenergy to incorporate enhanced safety standards in battery energy storage.
