2026 Tesla Model 3 Premium AWD, ME Charging Cost

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

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.

Where these figures come from

Every figure on this page traces to a named EIA or EPA dataset, see the methodology guide. Maine has some of the highest residential electricity rates in the country, see the guide to why the cost varies so much by state for the full picture.
