Louisiana home charging cost for the 2027 Rivian R1S Performance (20in)
In Louisiana, home electricity runs 13.51¢/kWh — put a 2027 Rivian R1S Performance (20in)'s EPA-rated 47 kWh/100mi against that and 100 miles costs $6.35, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home is much cheaper than gas here: 60.4% less than gas per mile, here specifically.
Annual cost, at 15 thousands miles a year
At fueleconomy.gov's default of 15,000 annual miles, the 2027 Rivian R1S Performance (20in) costs roughly $952 a year to charge at home in Louisiana, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,451 a year.
What one full charge costs
Covering the 2027 Rivian R1S Performance (20in)'s EPA-rated 348-mile range takes about 163.5 kWh, which costs about $22.09 at Louisiana's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.
Where this ranks
This combination ranks 10,836 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rivian R1S Performance (20in) alone ranks 369 of 400 models for efficiency; Louisiana alone ranks 8 of 51 states for electricity price.
Before you install a home charger in Louisiana
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.
