Arizona Public Service Co electricity rates

It serves 1.3 million residential customers, making it one of the larger utilities in Arizona. Its 16.45¢ per kilowatt-hour runs 8% above the Arizona average of 15.23¢.

Its customers use more electricity than the national norm, 1,034 kilowatt-hours a month against 871, which amplifies whatever the rate does.

A shareholder-owned company whose rates are set by the state regulator, including an approved return on the capital it has invested. That matters because a bill is not only the cost of generating electricity: it also carries the cost of the network, and who owns that network changes how it is paid for.

In 2024 the average Arizona Public Service Co customer went 87 minutes without electricity across 0.93 interruptions. The median across the 941 utilities that report this is 185 minutes.

That is markedly better than typical. Short outage durations usually mean an underground or heavily automated network, and they are expensive to achieve, which is part of why reliable systems often carry higher delivery charges.

Arizona Public Service Co offers time-of-use pricing and critical peak pricing to residential customers. 772,896 households were enrolled, about 61.5% of its residential base.

These plans are opt-in almost everywhere. They reward households that can move laundry, dishwashing, water heating or electric vehicle charging out of the late-afternoon peak, and they cost more than the standard rate for households that cannot. How to tell which group you are in.

182,632 residential customers had net-metered solar in 2024, totalling 1,643.36 megawatts. That works out to 145.4 installations per thousand customers, against a median of 8 across the utilities reporting it.

Adoption here is exceptionally high. That usually means some combination of a high retail rate worth displacing, strong sunshine and favourable export rules, and it tends to bring its own regulatory argument about who covers the fixed cost of the network. What exports are actually worth.
