2027 Rivian R1S Performance (20in AT): home charging cost in Alaska

In Alaska, home electricity runs 26.86¢/kWh — put a 2027 Rivian R1S Performance (20in AT)'s EPA-rated 49.8 kWh/100mi against that and 100 miles costs $13.39, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home is cheaper than gas here: 16.4% less than gas per mile, here specifically.

Annual cost, at 15 thousands miles a year

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2027 Rivian R1S Performance (20in AT) charged at home in Alaska costs about $2,008/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $395 a year.

What one full charge costs

A 2027 Rivian R1S Performance (20in AT) needs roughly 164 kWh to reach its EPA-rated 329-mile range, which runs about $44.04 at 26.86¢/kWh in Alaska.

How this compares nationally

This combination ranks 19,675 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rivian R1S Performance (20in AT) alone ranks 386 of 400 models for efficiency; Alaska alone ranks 44 of 51 states for electricity price.

Before you install a home charger in Alaska

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.
