2026 Rivian R1S Dual Max (20in), UT Charging Cost

2026 Rivian R1S Dual Max (20in): home charging cost in Utah

In Utah, home electricity runs 13.17¢/kWh, put a 2026 Rivian R1S Dual Max (20in)'s EPA-rated 42 kWh/100mi against that and 100 miles costs $5.53, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 65.5% less than gas per mile, here specifically.

What a year of driving costs

Driving 15,000 miles a year, fueleconomy.gov's own default assumption, a 2026 Rivian R1S Dual Max (20in) charged at home in Utah costs about $829/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,574 a year.

Cost of a full charge

A 2026 Rivian R1S Dual Max (20in) needs roughly 159.5 kWh to reach its EPA-rated 380-mile range, which runs about $21.01 at 13.17¢/kWh in Utah.

How this compares nationally

This combination ranks 7,157 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rivian R1S Dual Max (20in) alone ranks 298 of 400 models for efficiency; Utah alone ranks 4 of 51 states for electricity price.

Before you install a home charger in Utah

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. Utah is one of the cheapest states for home electricity, the guide to why the cost varies so much by state covers what drives that.
