EV Charging Cost in Hawaii
Updated September 2026 · average residential rates
The short answer: Hawaii's average residential electricity rate is 42.1¢/kWh — 149% above the U.S. average, ranking #51 cheapest of 51. A Tesla Model Y costs about $35.08 to fully charge at home here (12.0¢ per mile), and home charging saves roughly $0.00/month versus a comparable gas car at 1,000 miles.
What EV owners in Hawaii should know
Hawaii has the most expensive grid electricity in America — oil-fired generation on islands — and it's the one state where home charging can approach gas parity at standard rates. The playbook here is different: rooftop solar plus daytime charging, which flips Hawaii from the worst EV state to one of the best.
