Pending Base rate case, docket E-01345A-25-0105 before the Arizona Corporation Commission.
16.4% of the average Arizona bill of $160 (EIA, 2024); your own bill scales with your usage. Our arithmetic, not the utility's figure; the methodology page shows how.
APS is asking for a 16.44 percent residential increase, widely reported as about 20 dollars a month for a typical household. The same filing proposes a new extra high load factor class for data centers with a 47 percent class increase, meant to stop residential customers from subsidizing data center growth. Hearings wrapped in mid 2026 and a decision is expected toward the end of the year.
