2025 EIA bundled residential average

17.03¢per kWh

Historical annual average—not a current tariff.

EIA derives this average from reported residential revenue and sales. Your actual bill can differ because of current tariffs, fixed charges, taxes, riders, tiers, time-of-use pricing, and other bill components.

What “bundled” means

Supply and delivery are reported together.

We only use a provider headline when EIA reports bundled residential service. That makes the annual figure more complete than an energy-only or delivery-only component, but it still does not reproduce the provider's current rate schedule.

Why this page is in the reviewed cohort

Observed data with a reported territory.

This page met our publication criteria for bundled service, observed data, customer scale, a valid price, and county service-territory coverage. We then selected this provider/state pair for the smaller curated utility cohort.

Simple cost examples

What 17.03¢/kWh implies at common usage levels

500 kWh$85

1,000 kWh$170

1,500 kWh$255

These examples multiply usage by the historical annual average. They are not predictions of a Arizona Public Service Co bill.

Newer state context

Arizona's latest monthly residential average is 15.38¢/kWh.

That statewide figure is from July 2026, while the provider figure above is a 2025 annual average. The periods and populations differ, so this is context rather than a direct tariff comparison. See the Arizona rate page →
