How to pay less than the Hawaii average
- Ask your utility about an EV or time-of-use plan. Off-peak overnight rates are often far below the average. Our time-of-use savings calculator shows what that's worth.
- Schedule charging in your car's app or charger app so it starts after peak hours end.
- Check for charger rebates from your utility before you buy hardware. Many utilities offer them even though the federal charger credit has ended.
- Charge at home, not on fast chargers. Public DC fast charging averages around 41¢/kWh, more than double most home rates.
