Average price = residential revenue ÷ residential sales from each utility's federal EIA-861 filing (bundled service — supply + delivery + riders, not a quoted tariff rate). State average = 14.93¢/kWh, volume-weighted across these utilities (2024). Your distribution utility is fixed by address; these gaps measure what households in different territories actually paid. A further 7 competitive suppliers / solar lessors report energy-only or behind-the-meter sales in Arizona; their prices cover only part of the bill and are not comparable to the all-in figures above.

Heating: which fuel is cheapest per million BTU in Arizona?
| Fuel | Native price | As of | $ per MMBTU |
|---|---|---|---|
| Utility natural gas | $1.710 /therm | Feb 2026 | 17.10 |
| Electricity (resistance) | 16.03 ¢/kWh | Feb 2026 | 46.98 |
Utility natural gas is the cheapest residential energy per BTU in Arizona at $17.10/MMBTU. Conversions: 1 kWh = 3,412 BTU; 1 therm = 100,000 BTU; heating oil 138,500 BTU/gal; propane 91,452 BTU/gal. Site-energy prices — appliance efficiency changes delivered-heat cost: a 95% AFUE gas furnace delivers heat near the gas figure, while a heat pump at seasonal COP 2.5–3 cuts the effective electric figure by 60–70%. (No EIA weekly heating-oil survey price for Arizona.)
