Frequently asked questions
How often can I switch APS plans?
APS generally allows one plan change per 12 months, so run the numbers before you switch. Check your eligibility in your APS online account.
Which APS plan is cheapest for most homes?
It depends on when you use power. Homes that can keep 4–7pm weekday usage low usually do best on a time-of-use plan; steady low-usage homes sometimes win on the flat rate. Our calculator ranks all four plans for your exact usage.
