2027 Rivian R1T Quad (22in UHP): home charging cost in Hawaii

In Hawaii, home electricity runs 45.95¢/kWh — put a 2027 Rivian R1T Quad (22in UHP)'s EPA-rated 47.3 kWh/100mi against that and 100 miles costs $21.76, versus $16.02 for a gas car averaging 25.5 mpg. This model costs more to charge at home than gas would here: 35.8% more than gas per mile here, not less — the arithmetic isn't clamped to always favor charging.

What a year of driving costs

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2027 Rivian R1T Quad (22in UHP) charged at home in Hawaii costs about $3,263/year in electricity, against about $2,403/year for the gas-car comparison. That's about $860 MORE a year than the gas comparison, not less.

What one full charge costs

A 2027 Rivian R1T Quad (22in UHP) needs roughly 160 kWh to reach its EPA-rated 338-mile range, which runs about $73.53 at 45.95¢/kWh in Hawaii.

How this compares nationally

This combination ranks 20,365 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rivian R1T Quad (22in UHP) alone ranks 372 of 400 models for efficiency; Hawaii alone ranks 51 of 51 states for electricity price.

Getting set up to charge a 2027 Rivian R1T Quad (22in UHP) 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

See the methodology guide for exactly which EIA and EPA figures feed 2027 Rivian R1T Quad (22in UHP)'s cost in Hawaii. 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.
