Alaska home charging cost for the 2027 Rivian R1S Performance (20in)

A 2027 Rivian R1S Performance (20in) draws 47 kWh per 100 miles per the EPA; at Alaska's 26.86¢/kWh residential rate that's $12.62 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. Charging at home is cheaper than gas here: 21.2% less than gas per mile, here specifically.

Next step: home charger installation

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.
