South Carolina home charging cost for the 2026 Rivian R1T Dual Max (20in)

A 2026 Rivian R1T Dual Max (20in) draws 42 kWh per 100 miles per the EPA; at South Carolina's 16.04¢/kWh residential rate that's $6.73 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. Charging at home is much cheaper than gas here: 58% 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.
