Texas home charging cost for the 2027 Rivian R1S Performance (22in)

A 2027 Rivian R1S Performance (22in) draws 44.6 kWh per 100 miles per the EPA; at Texas's 16.11¢/kWh residential rate that's $7.18 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: 55.2% less than gas per mile, here specifically.

What a year of driving costs

At fueleconomy.gov's default of 15,000 annual miles, the 2027 Rivian R1S Performance (22in) costs roughly $1,077 a year to charge at home in Texas, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,326 a year.

Cost of a full charge

Covering the 2027 Rivian R1S Performance (22in)'s EPA-rated 371-mile range takes about 165.4 kWh, which costs about $26.64 at Texas'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 13,505 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rivian R1S Performance (22in) alone ranks 354 of 400 models for efficiency; Texas alone ranks 28 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.
