Hawaii home charging cost for the 2026 Cadillac VISTIQ (19 kW Charger)

In Hawaii, home electricity runs 45.95¢/kWh — put a 2026 Cadillac VISTIQ (19 kW Charger)'s EPA-rated 39.3 kWh/100mi against that and 100 miles costs $18.08, versus $16.02 for a gas car averaging 25.5 mpg. This model costs more to charge at home than gas would here: 12.9% more than gas per mile here, not less — the arithmetic isn't clamped to always favor charging.

What a year of driving costs

At fueleconomy.gov's default of 15,000 annual miles, the 2026 Cadillac VISTIQ (19 kW Charger) costs roughly $2,712 a year to charge at home in Hawaii, against roughly $2,403 a year for an equivalent gas car. That's about $309 MORE a year than the gas comparison, not less.

Cost of a full charge

Covering the 2026 Cadillac VISTIQ (19 kW Charger)'s EPA-rated 300-mile range takes about 118 kWh, which costs about $54.24 at Hawaii's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

Next step: home charger installation

The numbers above assume Level 2 home charging is already in place — the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.

Where these figures come from

Every figure on this page traces to a named EIA or EPA dataset — see the methodology guide. This is one of the combinations where charging costs more than gas — the guide to when that happens explains why the arithmetic can go either way.
