Louisiana home charging cost for the 2026 Rivian R1S Performance Dual Large Plus (22in)

In Louisiana, home electricity runs 13.51¢/kWh — put a 2026 Rivian R1S Performance Dual Large Plus (22in)'s EPA-rated 40.9 kWh/100mi against that and 100 miles costs $5.53, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 65.5% less than gas per mile, here specifically.

What a year of driving costs

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.
