Peak & off-peak hours

Peak · 4pm–7pm weekdays year-round

Off-peak · All other hours; winter super off-peak 10am–3pm weekdays (Nov–Apr billing cycles)

Illustrative timeline — exact windows vary by season and rate schedule.

Is the TOU or EV plan worth it?

If you drive 700+ miles/month and can charge overnight or on weekends, Arizona Public Service's time-varying rate often saves money — peak rates can run 9.8× off-peak. If most of your usage happens during peak hours (often late afternoon), TOU may cost more than a flat plan.

Solar & net metering

Arizona Public Service uses avoided cost net metering with export credits around $0.08/kWh. Solar customers can generally combine net metering with eligible TOU plans — timing self-consumption vs export matters for savings.

Example EV charging savings

Typical EV: 11,000 miles/year (3,143 kWh)

Scenario	Est. annual cost
Charge during peak ($0.34/kWh)	$1,081/yr
Charge off-peak ($0.04/kWh)	$110/yr
Estimated savings (off-peak vs peak)	$971/yr

Assumes 11,000 mi/yr, 3.5 mi/kWh, and 100% of EV charging at each rate tier. Real savings depend on your driving, charger, and schedule.
