Arizona Public Service's final public hearing on a proposed 14% residential electricity rate hike opens at 10 a.m. Monday, giving ratepayers one last chance to speak before the case moves to an administrative law judge. The session runs until 1 p.m. or when the last caller finishes. Callers can join at 877-309-3457 using passcode 801972877.
The proposal, reported by KTAR, would raise the typical household bill by $20 a month. Data centers face a sharper ask: a 45% rate increase under the same filing.
Monday's session is the fifth stage of an eight-part rate adjustment process. Four earlier public comment hearings ran in January and February. After Monday, the Arizona Corporation Commission and involved parties move to an evidentiary hearing before an administrative law judge, who will draft a recommended opinion and order. An ACC vote has not yet been scheduled.
Why is the ACC considering another APS increase so soon?
APS submitted the rate hike proposal in June 2025, just 16 months after the ACC approved an 8% increase that added about $10 to $12 per month to the typical residential bill. The utility says current rates do not support the rising cost of maintaining grid reliability and infrastructure.
APS, owned by publicly traded Pinnacle West Capital Corp., serves about 1.4 million customers statewide, including Phoenix and Valley suburbs to the west and north. Arizona Attorney General Kris Mayes, who was granted intervention status in the rate case, called the proposed hike a "blatant" grab for profits.

If approved, new rates would become effective no earlier than July 8, 2026, according to ABC15. An ACC vote date has not been set.
