Slate Reality Check · Denver, CO
Slate truck in Denver, CO
Winter range, charging cost and how far it goes, worked out for Denver's weather, grid and prices.
Denver's winters are cool rather than cold: on a typical January day (32°F) a Slate gets an estimated 171 miles, 16% under its 205-mile rating, about the same as in the coldest week (around December 19, when it averages 31°F). By May it's back to about 202. Charging at home at Colorado's average rate (17.0¢/kWh) costs about $65 a month for 38 miles a day, against $189 for a gas Ford Maverick on Denver's gas. Denver's grid (WECC Rockies) is 35% dirtier than the US average, but charging on it still makes 55% less CO₂ than gas.
Estimated. Almost no one's driving a Slate yet, so these come from 1,548 real drives in other EVs at each temperature (and Recurrent's winter study below freezing), applied to the Slate's rating. They switch to real Slate drives as owners log them.

Questions Denver drivers ask
How far can a Slate go in a Denver winter?
About 171 miles on a typical January day (32°F) and about the same in the coldest week of the year (around December 19, 31°F on average), estimated from real EV drives at those temperatures. That's 16% below its 205-mile rating, mostly from heating the cabin and the battery. Denver averages 29 days a year below freezing.
How much does it cost to charge a Slate in Denver?
About $65 a month at home for 38 miles a day, at Colorado's average home electricity rate of 17.0¢/kWh: about 5.6¢ a mile. A gas Ford Maverick on Denver's average gas ($4.24 a gallon) costs about $189 a month for the same driving.
Can I charge a Slate on a regular 120 V outlet in Denver?
At 38 miles a day, yes, all year: a 120 V outlet adds about 42 miles in 12 hours even in Denver's coldest week, and about 49 on an average day.
Is it greener to drive electric on Denver's grid?
Yes. Denver's grid (WECC Rockies) is 35% dirtier than the US average, but a Slate charged on it still makes 55% less CO₂ than a gas Ford Maverick.
