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, Idaho Power's time-varying rate often saves money — peak rates can run 4.0× 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

Solar/net-metering customers may be ineligible for some TOU schedules — verify with your utility before switching rate plans.

Example EV charging savings

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

Scenario	Est. annual cost
Charge during peak ($0.30/kWh)	$940/yr
Charge off-peak ($0.07/kWh)	$235/yr
Estimated savings (off-peak vs peak)	$705/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.
