What charging actually costs here

Filling a Tesla Model S from empty in Hawaii costs $58.58. The car draws 111.1 kWh from the wall for a full 410-mile charge, and Hawaii residential electricity averages 52.72¢ per kWh. That works out at $14.29 per 100 miles, or $0.14 a mile.

Hawaii is more expensive than average: 52.72¢ against a national mean of 19.42¢, which ranks it 51 of 51 for electricity price. The same car costs $14.57 to fill in Nevada and $58.58 in Hawaii — a 4.0× spread across the country for identical driving.

This is one of the few places where the sum does not favour electricity. At 52.72¢ per kWh, running the Tesla Model S costs $14.29 per 100 miles while a 30 mpg petrol car costs $13.62 — so over 12,000 miles you would spend about $80 more on electricity. Home solar or an off-peak tariff changes that quickly, but the flat residential rate does not.

Frequently asked questions

How much does it cost to charge a Tesla Model S in Hawaii?

$58.58 for a full charge from empty. The car needs 111.1 kWh at the wall and Hawaii residential electricity averages 52.72¢ per kWh.

How much does a Tesla Model S cost per mile in Hawaii?

About $0.14 a mile, or $14.29 per 100 miles. Over 12,000 miles a year that is roughly $1,714 of electricity.

Is charging a Tesla Model S cheaper than petrol in Hawaii?

Not at the flat residential rate. Electricity costs $14.29 per 100 miles here against $13.62 for a 30 mpg petrol car, so you would spend roughly $80 more a year. Hawaii has the kind of electricity prices where an off-peak tariff or solar makes the difference.

How long does a full charge last?

The EPA rates the Tesla Model S at 410 miles combined. Cold weather, motorway speeds and a loaded car all reduce that; the EPA number is a standardised test, not a guarantee.

Does this include charging losses?

Yes. The EPA's 27.1 kWh/100 mi figure is measured at the wall socket, so the energy lost in the charger and cabling is already in the number. No extra efficiency factor is applied.
