North Carolina home charging cost for the 2026 Rivian R1S Quad Max (22in UHP)

In North Carolina, home electricity runs 14.9¢/kWh — put a 2026 Rivian R1S Quad Max (22in UHP)'s EPA-rated 47.3 kWh/100mi against that and 100 miles costs $7.05, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home is much cheaper than gas here: 56% less than gas per mile, here specifically.

What a year of driving costs

At fueleconomy.gov's default of 15,000 annual miles, the 2026 Rivian R1S Quad Max (22in UHP) costs roughly $1,058 a year to charge at home in North Carolina, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,345 a year.

Cost of a full charge

Covering the 2026 Rivian R1S Quad Max (22in UHP)'s EPA-rated 338-mile range takes about 160 kWh, which costs about $23.84 at North Carolina's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

How this compares nationally

This combination ranks 13,163 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rivian R1S Quad Max (22in UHP) alone ranks 373 of 400 models for efficiency; North Carolina alone ranks 18 of 51 states for electricity price.

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.

Ask a licensed North Carolina electrician to quote the install before this math becomes a real decision.
