Utilities and rate plans
Each utility’s current residential tariffs, transcribed from its tariff sheets, with periods, tiers, fixed charge and a typical bill. Customer counts from EIA-861 (2025).
Each row prices a utility’s standard plan for a typical home. The Arizona average of 15.39¢/kWh (EIA, 12 months) is what every household in the state actually paid, including utilities not modeled here and discounted low-income bills, so it can sit below every row.
SRP sets its monthly service charge by service size; the plans shown use Tier 2 ($30), the size of a typical single-family house (up to 225 A). E-21, E-26 and E-29 closed to new customers in November 2025.

Charging an electric car in Arizona
Driving a Tesla Model Y Long Range AWD 1,000 miles a month takes 275 kWh from the wall (EPA 27.5 kWh/100 mi), about $42 at the state average. A 25.5 mpg gasoline car covering the same distance at $5.02 a gallon (West Coast except California (PADD 5) average, October 2026) costs about $197.
Some utilities, such as APS, sell EV plans with cheaper overnight hours. The table shows, for each utility, the plan with the lowest total bill for a typical Arizona home that adds 1,000 EV miles a month, averaged over the year, and what plugging in at 6 pm would cost instead.
Over the last 12 months the average price was 15.39¢ per kWh and the average home used 1,054 kWh a month, so a typical Arizona household spent about $162 a month on electricity, or $1,947 a year. Use is 20% above the US average of 875 kWh a month, peaking in August at 1,789 kWh.
The state average hides the real spread. Utilities in the same state charge different prices, and on a time-of-use plan the same kWh costs more in the peak hours than off-peak; each utility page shows by how much. Open APS’s page to see its plans, prices by hour and fixed charge, or run the calculators below with Arizona preloaded.
Natural gas for homes averaged $1.98 per therm over the 12 months to August 2026 (EIA, all charges included), and a typical gas-heated home uses about 126 therms a year for heating. The heat pump calculator compares that with electric heating on your plan.
A south-facing, 20° rooftop array in Arizona produces about 1,750 kWh per installed kW a year (NREL PVWatts at the state’s population center). What that is worth depends on your utility’s export rule, shown on each utility’s page.
