AARP Arizona’s Intervention in APS Rate Case Approved

This week, an administrative law judge with the Arizona Corporation Commission approved AARP Arizona’s intervention in the 2025 APS rate case. (Docket No. A-25-0105). As an advocate for the nearly 2.5 million Arizonans age 50 and older, AARP is deeply concerned about the impact of APS’s proposal on residential customers—particularly those living on fixed or limited incomes.

APS’s application seeks to increase electricity rates for residential customers by double digits %, with nearly 90% of customers expected to see a minimum 12% increase in their monthly bills. This increase comes on the heels of a 2022 rate case, approved in February 2024, which also resulted in a double-digit increase in residential rates.

The utility’s application also seeks to gut traditional regulatory review, replacing it with a formula rate scheme that would fast-track annual rate increases.

AARP has hired an expert witness, Paul Alvarez of the Wired Group, who will file testimony in the proceeding.

AARP Arizona looks forward to participating in this proceeding to keep utility service affordable and reliable for the customers of the Grand Canyon state’s largest utility.
