2026 Rivian R1T Performance Dual Large (22in): home charging cost in Hawaii

In Hawaii, home electricity runs 45.95¢/kWh — put a 2026 Rivian R1T Performance Dual Large (22in)'s EPA-rated 39.5 kWh/100mi against that and 100 miles costs $18.14, versus $16.02 for a gas car averaging 25.5 mpg. This model costs more to charge at home than gas would here: 13.2% more than gas per mile here, not less — the arithmetic isn't clamped to always favor charging.

Annual cost, at 15 thousands miles a year

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Rivian R1T Performance Dual Large (22in) charged at home in Hawaii costs about $2,721/year in electricity, against about $2,403/year for the gas-car comparison. That's about $318 MORE a year than the gas comparison, not less.

Cost of a full charge

A 2026 Rivian R1T Performance Dual Large (22in) needs roughly 129.9 kWh to reach its EPA-rated 329-mile range, which runs about $59.67 at 45.95¢/kWh in Hawaii.

Getting set up to charge a 2026 Rivian R1T Performance Dual Large (22in) at home

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.
