2025 Tesla Model Y in Chattanooga, TN
Winter range, charging cost and how far it goes, worked out for Chattanooga's weather, grid and prices.
Chattanooga's winters are cool rather than cold: on a typical January day (42°F) a Model Y gets an estimated 258 miles, 7% under its 277-mile rating, about the same as in the coldest week (around January 11, when it averages 41°F). By June it's back to about 295. Charging at home at Tennessee's average rate (13.7¢/kWh) costs about $52 a month for 38 miles a day, about a third of the $200 an average small SUV costs on the Midwest's gas. Chattanooga's grid (SERC Tennessee Valley) is 17% dirtier than the US average, but charging on it still makes 64% less CO₂ than gas.
Partly estimated. 2 of 5 temperature bands are from 139 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 277-mile rating. Each band switches to its own drives once it has 20 from 3 drivers.

Questions Chattanooga drivers ask
How far can a Model Y go in a Chattanooga winter?
About 258 miles on a typical January day (42°F) and about the same in the coldest week of the year (around January 11, 41°F on average), estimated from real EV drives at those temperatures. That's 7% below its 277-mile rating, mostly from heating the cabin and the battery.
How much does it cost to charge a Model Y in Chattanooga?
About $52 a month at home for 38 miles a day, at Tennessee's average home electricity rate of 13.7¢/kWh: about 4.5¢ a mile. An average small SUV on the Midwest's average gas ($4.14 a gallon) costs about $200 a month for the same driving.
Can I charge a Model Y on a regular 120 V outlet in Chattanooga?
At 38 miles a day, yes, all year: a 120 V outlet adds about 45 miles in 12 hours even in Chattanooga's coldest week, and about 47 on an average day.
Is it greener to drive electric on Chattanooga's grid?
Yes. Chattanooga's grid (SERC Tennessee Valley) is 17% dirtier than the US average, but a Model Y charged on it still makes 64% less CO₂ than an average small SUV.
