2025 GMC Sierra EV in Louisville, KY
Winter range, charging cost and how far it goes, worked out for Louisville's weather, grid and prices.
Louisville's winters are cool rather than cold: on a typical January day (35°F) a Sierra EV gets an estimated 332 miles, 15% under its 390-mile rating, about the same as in the coldest week (around January 14, when it averages 35°F). By April it's back to about 385. Charging at home at Kentucky's average rate (13.8¢/kWh) costs about $90 a month for 38 miles a day, about a third of the $300 a gas Sierra costs on the Midwest's gas. Louisville's grid (SERC Tennessee Valley) is 17% dirtier than the US average, but charging on it still makes 59% 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 Louisville drivers ask
How far can a Sierra EV go in a Louisville winter?
About 332 miles on a typical January day (35°F) and about the same in the coldest week of the year (around January 14, 35°F on average), estimated from real EV drives at those temperatures. That's 15% below its 390-mile rating, mostly from heating the cabin and the battery.
How much does it cost to charge a Sierra EV in Louisville?
About $90 a month at home for 38 miles a day, at Kentucky's average home electricity rate of 13.8¢/kWh: about 7.8¢ a mile. A gas Sierra on the Midwest's average gas ($4.14 a gallon) costs about $300 a month for the same driving.
Can I charge a Sierra EV on a regular 120 V outlet in Louisville?
Not at 38 miles a day: a 120 V outlet adds only about 29 miles in 12 hours on an average day (25 in the coldest week). Plan on 240 V, which fills it from 10% in about 10 hours.
Is it greener to drive electric on Louisville's grid?
Yes. Louisville's grid (SERC Tennessee Valley) is 17% dirtier than the US average, but a Sierra EV charged on it still makes 59% less CO₂ than a gas Sierra.
