2026 Tesla Model Y in Boise, ID
Winter range, charging cost and how far it goes, worked out for Boise's weather, grid and prices.
Boise's winters are cool rather than cold: on a typical January day (32°F) a Model Y gets an estimated 260 miles, 15% under its 306-mile rating, and about 255 in the coldest week (around December 24, when it averages 31°F). By March it's back to about 295. Charging at home at Idaho's average rate (13.7¢/kWh) costs about $51 a month for 38 miles a day, about a third of the $215 an average small SUV costs on the Rocky Mountains's gas. And Boise's grid (WECC Northwest), 18% cleaner than the US average, makes it 75% less CO₂ than gas.
Partly estimated. 2 of 5 temperature bands are from 108 real drives of this model; the rest come from 1,548 real drives in EVs at each temperature (and Recurrent's winter study below freezing), applied to its 306-mile rating. Each band switches to its own drives once it has 20 from 3 drivers.

Questions Boise drivers ask
How far can a Model Y go in a Boise winter?
About 260 miles on a typical January day (32°F) and about 255 in the coldest week of the year (around December 24, 31°F on average), estimated from real EV drives at those temperatures. That's 15–17% below its 306-mile rating, mostly from heating the cabin and the battery. Boise averages 33 days a year below freezing.
How much does it cost to charge a Model Y in Boise?
About $51 a month at home for 38 miles a day, at Idaho's average home electricity rate of 13.7¢/kWh: about 4.4¢ a mile. An average small SUV on the Rocky Mountains's average gas ($4.47 a gallon) costs about $215 a month for the same driving.
Can I charge a Model Y on a regular 120 V outlet in Boise?
At 38 miles a day, yes, all year: a 120 V outlet adds about 43 miles in 12 hours even in Boise's coldest week, and about 49 on an average day.
Is it greener to drive electric on Boise's grid?
Yes, more than most places. Boise's grid (WECC Northwest) is 18% cleaner than the US average, so a Model Y charged on it makes 75% less CO₂ than an average small SUV.
