About 246 miles on a typical January day (29°F) and about 243 in the coldest week of the year (around January 21, 28°F on average), estimated from real EV drives at those temperatures.

About $91 a month at home for 38 miles a day, at Connecticut's average home electricity rate of 24.2¢/kWh: about 7.9¢ a mile. An average small SUV on New England's average gas ($4.25 a gallon) costs about $205 a month for the same driving.
Can I charge a Model Y on a regular 120 V outlet in Hartford?
At 38 miles a day, yes, all year: a 120 V outlet adds about 41 miles in 12 hours even in Hartford's coldest week, and about 49 on an average day.
