2026 Tesla Model 3 Premium AWD: home charging cost in Maine

In Maine, home electricity runs 29.67¢/kWh — put a 2026 Tesla Model 3 Premium AWD's EPA-rated 26.4 kWh/100mi against that and 100 miles costs $7.83, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home is much cheaper than gas here: 51.1% less than gas per mile, here specifically.

Annual cost, at 15 thousands miles a year

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Tesla Model 3 Premium AWD charged at home in Maine costs about $1,174/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,229 a year.

What one full charge costs

A 2026 Tesla Model 3 Premium AWD needs roughly 91.3 kWh to reach its EPA-rated 346-mile range, which runs about $27.08 at 29.67¢/kWh in Maine.

Where this ranks

This combination ranks 14,804 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Tesla Model 3 Premium AWD alone ranks 12 of 400 models for efficiency; Maine alone ranks 48 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 Maine electrician to quote the install before this math becomes a real decision.
