2025 GMC Sierra EV in Provo, UT
Winter range, charging cost and how far it goes, worked out for Provo's weather, grid and prices.
Provo's winters are cool rather than cold: on a typical January day (33°F) a Sierra EV gets an estimated 319 miles, 18% under its 390-mile rating, and about 313 in the coldest week (around December 26, when it averages 32°F). By April it's back to about 378. Summer costs range here too: at July's 79°F average (highs near 95°F), air conditioning trims it to about 357 miles. Charging at home at Utah's average rate (13.1¢/kWh) costs about $87 a month for 38 miles a day, about a third of the $323 a gas Sierra costs on the Rocky Mountains's gas. And Provo's grid (WECC Northwest), 18% cleaner than the US average, makes it 71% less CO₂ than gas.
Partly estimated. 2 of 5 temperature bands are from 116 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 390-mile rating. Each band switches to its own drives once it has 20 from 3 drivers.

Questions Provo drivers ask
How far can a Sierra EV go in a Provo winter?
About 319 miles on a typical January day (33°F) and about 313 in the coldest week of the year (around December 26, 32°F on average), estimated from real EV drives at those temperatures. That's 18–20% below its 390-mile rating, mostly from heating the cabin and the battery. Provo averages 21 days a year below freezing.
How much does it cost to charge a Sierra EV in Provo?
About $87 a month at home for 38 miles a day, at Utah's average home electricity rate of 13.1¢/kWh: about 7.5¢ a mile. A gas Sierra on the Rocky Mountains's average gas ($4.47 a gallon) costs about $323 a month for the same driving.
Can I charge a Sierra EV on a regular 120 V outlet in Provo?
Not at 38 miles a day: a 120 V outlet adds only about 29 miles in 12 hours on an average day (24 in the coldest week). Plan on 240 V, which fills it from 10% in about 10 hours.
Is it greener to drive electric on Provo's grid?
Yes, more than most places. Provo's grid (WECC Northwest) is 18% cleaner than the US average, so a Sierra EV charged on it makes 71% less CO₂ than a gas Sierra.
