Analysis of Arizona Public Service's Integrated Resource Plan

Arizona Public Service Company (APS) submitted its 2020 Integrated Resource Plan (IRP) to the Arizona Corporation Commission (ACC) on June 26, 2020. The Southwest Energy Efficiency Project (SWEEP) partnered with Strategen to conduct grid modeling and technical analysis to identify portfolios that meet the utility’s stated clean energy commitments and maintain affordable and reliable service for customers, and  explore whether additional environmental and economic savings could be achieved. 

Although affordability, grid reliability, and environmental benefits are frequently presented as competing interests, this analysis reveals that they can co-exist without significant trade-offs and can be simultaneously maximized with strategic investment and operational choices. Energy efficiency (EE), renewable energy (RE) resources, and energy storage technologies are becoming more affordable, while also providing flexibility and significant environmental benefits without impacting reliability.
