2025 GMC Sierra EV in Rochester, NY
Winter range, charging cost and how far it goes, worked out for Rochester's weather, grid and prices.
In a typical Rochester January (26°F), a Sierra EV gets an estimated 285 miles on a charge, 27% less than its 390-mile rating, and about 281 miles in the coldest week of the year (around January 23, when it averages 25°F). By May it's back to about 386. Power is pricey in New York (29.9¢/kWh), so charging at home costs about $203 a month for 38 miles a day, still less than the $312 a gas Sierra costs on New York's gas. And Rochester's grid (NPCC Upstate NY), 68% cleaner than the US average, makes it 88% 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 Rochester drivers ask
How far can a Sierra EV go in a Rochester winter?
About 285 miles on a typical January day (26°F) and about 281 in the coldest week of the year (around January 23, 25°F on average), estimated from real EV drives at those temperatures. That's 27–28% below its 390-mile rating, mostly from heating the cabin and the battery. Rochester averages 80 days a year below freezing.
How much does it cost to charge a Sierra EV in Rochester?
About $203 a month at home for 38 miles a day, at New York's average home electricity rate of 29.9¢/kWh: about 17.6¢ a mile. A gas Sierra on New York's average gas ($4.31 a gallon) costs about $312 a month for the same driving.
Can I charge a Sierra EV on a regular 120 V outlet in Rochester?
Not at 38 miles a day: a 120 V outlet adds only about 29 miles in 12 hours on an average day (21 in the coldest week). Plan on 240 V, which fills it from 10% in about 10 hours.
Is it greener to drive electric on Rochester's grid?
Yes, more than most places. Rochester's grid (NPCC Upstate NY) is 68% cleaner than the US average, so a Sierra EV charged on it makes 88% less CO₂ than a gas Sierra.
