Wyoming home charging cost for the 2026 Tesla Model 3 Performance

In Wyoming, home electricity runs 13.88¢/kWh — put a 2026 Tesla Model 3 Performance's EPA-rated 29.6 kWh/100mi against that and 100 miles costs $4.11, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 74.4% 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 2026 Tesla Model 3 Performance costs roughly $616 a year to charge at home in Wyoming, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,787 a year.

Filling up the 2026 Tesla Model 3 Performance, in dollars

Covering the 2026 Tesla Model 3 Performance's EPA-rated 309-mile range takes about 91.4 kWh, which costs about $12.69 at Wyoming's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

Where this ranks

Before you install a home charger in Wyoming

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 Wyoming electrician to quote the install before this math becomes a real decision.
