Idaho home charging cost for the 2026 Tesla Model X Plaid

A 2026 Tesla Model X Plaid draws 33.7 kWh per 100 miles per the EPA; at Idaho's 12.8¢/kWh residential rate that's $4.31 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: 73.1% less than gas per mile, here specifically.

What a year of driving costs

At fueleconomy.gov's default of 15,000 annual miles, the 2026 Tesla Model X Plaid costs roughly $647 a year to charge at home in Idaho, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,756 a year.

What one full charge costs

Covering the 2026 Tesla Model X Plaid's EPA-rated 335-mile range takes about 112.9 kWh, which costs about $14.45 at Idaho'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 1,752 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Tesla Model X Plaid alone ranks 117 of 400 models for efficiency; Idaho alone ranks 3 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.

Where these figures come from

Every figure on this page traces to a named EIA or EPA dataset — see the methodology guide. Idaho is one of the cheapest states for home electricity — the guide to why the cost varies so much by state covers what drives that.
