2026 Tesla Model Y in Chattanooga, TN
Winter range, charging cost and how far it goes, worked out for Chattanooga's weather, grid and prices.
Winter barely touches range in Chattanooga: at a typical January's 42°F, a Model Y gets an estimated 296 miles on a charge, within 3% of its 306-mile rating. Charging at home at Tennessee's average rate (13.7¢/kWh) costs about $50 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 66% less CO₂ than gas.
Partly estimated. 2 of 5 temperature bands are from 108 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 306-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?
Chattanooga's winters are mild: about 296 miles on a typical January day (42°F) and about the same in the coldest week (around January 11, 41°F), estimated from real EV drives at those temperatures. That's within 3% of its 306-mile rating.

About $50 a month at home for 38 miles a day, at Tennessee's average home electricity rate of 13.7¢/kWh: about 4.3¢ 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 50 miles in 12 hours even in Chattanooga's coldest week, and about 49 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 66% less CO₂ than an average small SUV.
