Understanding Your Bill
Your APS bill includes several components: base charges, energy charges, fuel adjustments, taxes, and fees.
Arizona Public Service residential rates typically range from 12–18¢/kWh depending on your rate plan. APS offers multiple rate plans including time-of-use, demand-based, and flat rate options. Your effective rate includes base charges, energy charges, and various surcharges.
Why is my APS bill so high?
High APS bills are commonly caused by Arizona's extreme summer heat (AC costs), demand charges on certain rate plans, or being on a suboptimal rate plan. APS's demand-based plans can result in high bills if usage peaks during on-peak hours.
How can I verify my APS bill is correct?
Upload your APS bill to Utility Check. We verify your rate plan, recalculate energy and demand charges, check time-of-use periods, and validate all surcharges against APS's published tariffs.
Does Utility Check support APS?
Yes. Utility Check fully supports Arizona Public Service bill verification. We analyze your rate plan, verify energy and demand charges, and validate all surcharges on your bill.
