2026 Tesla Model X: home charging cost in Rhode Island

In Rhode Island, home electricity runs 29.45¢/kWh — put a 2026 Tesla Model X's EPA-rated 32.2 kWh/100mi against that and 100 miles costs $9.48, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home is much cheaper than gas here: 40.8% 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.
