2024 Chevrolet Silverado EV 3WT in Spokane, WA
Winter range, charging cost and how far it goes, worked out for Spokane's weather, grid and prices.
Spokane's winters are cool rather than cold: on a typical January day (32°F) a Silverado EV 3WT gets an estimated 350 miles, 11% under its 393-mile rating, and about 342 in the coldest week (around December 21, when it averages 31°F). By March it's back to about 412. Charging at home at Washington's average rate (14.7¢/kWh) costs about $87 a month for 38 miles a day, about a third of the $363 a gas Silverado costs on Washington's gas. And Spokane's grid (WECC Northwest), 18% cleaner than the US average, makes it 72% less CO₂ than gas.
Partly estimated. 3 of 5 temperature bands are from 169 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 393-mile rating. Each band switches to its own drives once it has 20 from 3 drivers.

Questions Spokane drivers ask
How far can a Silverado EV 3WT go in a Spokane winter?
About 350 miles on a typical January day (32°F) and about 342 in the coldest week of the year (around December 21, 31°F on average), estimated from real EV drives at those temperatures. That's 11–13% below its 393-mile rating, mostly from heating the cabin and the battery. Spokane averages 41 days a year below freezing.
How much does it cost to charge a Silverado EV 3WT in Spokane?
About $87 a month at home for 38 miles a day, at Washington's average home electricity rate of 14.7¢/kWh: about 7.6¢ a mile. A gas Silverado on Washington's average gas ($5.33 a gallon) costs about $363 a month for the same driving.
Can I charge a Silverado EV 3WT on a regular 120 V outlet in Spokane?
Not at 38 miles a day: a 120 V outlet adds only about 32 miles in 12 hours on an average day (27 in the coldest week). Plan on 240 V, which fills it from 10% in about 10 hours.
Is it greener to drive electric on Spokane's grid?
Yes, more than most places. Spokane's grid (WECC Northwest) is 18% cleaner than the US average, so a Silverado EV 3WT charged on it makes 72% less CO₂ than a gas Silverado.
