2025 GMC Sierra EV in Providence, RI
Winter range, charging cost and how far it goes, worked out for Providence's weather, grid and prices.
In a typical Providence January (30°F), a Sierra EV gets an estimated 307 miles on a charge, 21% less than its 390-mile rating, and about 303 miles in the coldest week of the year (around January 20, when it averages 30°F). By May it's back to about 386. Power is pricey in Rhode Island (28.3¢/kWh), so charging at home costs about $188 a month for 38 miles a day, still less than the $307 a gas Sierra costs on New England's gas. And Providence's grid (NPCC New England), 30% cleaner than the US average, makes it 75% 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 Providence drivers ask
How far can a Sierra EV go in a Providence winter?
About 307 miles on a typical January day (30°F) and about 303 in the coldest week of the year (around January 20, 30°F on average), estimated from real EV drives at those temperatures. That's 21–22% below its 390-mile rating, mostly from heating the cabin and the battery. Providence averages 46 days a year below freezing.
How much does it cost to charge a Sierra EV in Providence?
About $188 a month at home for 38 miles a day, at Rhode Island's average home electricity rate of 28.3¢/kWh: about 16.2¢ a mile. A gas Sierra on New England's average gas ($4.25 a gallon) costs about $307 a month for the same driving.
Can I charge a Sierra EV on a regular 120 V outlet in Providence?
Not at 38 miles a day: a 120 V outlet adds only about 29 miles in 12 hours on an average day (23 in the coldest week). Plan on 240 V, which fills it from 10% in about 10 hours.
Is it greener to drive electric on Providence's grid?
Yes, more than most places. Providence's grid (NPCC New England) is 30% cleaner than the US average, so a Sierra EV charged on it makes 75% less CO₂ than a gas Sierra.
