WRA’s Stakeholder Comments on Arizona Public Service’s Integrated Resource Plan

An Integrated Resource Plan (IRP) is a tool for utilities and regulators to determine which mix of resources will meet energy demand while keeping costs low and mitigating risk. The IRP process requires utilities to use analytical tools to fairly evaluate and compare the costs and benefits of different kinds of resources. Integrated Resource Planning presents an opportunity for utilities in Arizona to demonstrate to the Arizona Corporation Commission that Arizona’s families and businesses will have affordable, reliable, and sustainable energy for the next 15 years.

While WRA recommends that the Commission acknowledge APS’s IRP in the fall 2024, we presented detailed suggestions on how the utility can present a revised IRP with stronger commitments to clean energy resource procurement and greenhouse gas emissions reductions. WRA also offered suggestions on how the Commission can improve the overall IRP process.
