Tennessee home charging cost for the 2026 Tesla Model X
A 2026 Tesla Model X draws 32.2 kWh per 100 miles per the EPA; at Tennessee's 13.9¢/kWh residential rate that's $4.48 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. Charging at home costs a fraction of what gas would here: 72.1% 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 X costs roughly $671 a year to charge at home in Tennessee, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,732 a year.
What one full charge costs
Covering the 2026 Tesla Model X's EPA-rated 352-mile range takes about 113.4 kWh, which costs about $15.76 at Tennessee's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.
Where this ranks
This combination ranks 2,353 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Tesla Model X alone ranks 95 of 400 models for efficiency; Tennessee alone ranks 13 of 51 states for electricity price.
Getting set up to charge a 2026 Tesla Model X at home
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 Tennessee 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. At 13.9¢/kWh, Tennessee sits in the middle of the national range — the guide to why charging cost varies by state shows where.
