APS issues All Source RFP and Battery Energy Storage RFP

Arizona Public Service Company (APS) has issued two Request for Proposals that are designed to meet APS’s future capacity needs and support its commitment to serving its customers with clean, reliable and affordable power. In the All Source RFP, APS seeks capacity resources to meet APS system peak load; and a Battery Energy Storage RFP to equip existing APS solar plants with battery storage.

In the All Source RFP, APS requests renewable energy resources of approximately 300-400 megawatts and capacity resources of approximately 200-300 megawatts. 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.

In the Battery Energy Storage RFP, APS requests a combined total of 60MWs of battery storage additions to two of its existing solar facilities located in Yavapai and Pinal Counties. The requested capacity enables APS’s existing solar resources to help meet peak needs and reliably with clean power, even when the sun is not shining. Proposed projects must be able to begin delivery no later than June 1, 2023.

The entire RFP process will be monitored and reviewed by a third-party independent monitor.
