By June it's back to about 423. Charging at home at Ohio's average rate (19.4¢/kWh) costs about $118 a month for 38 miles a day, against $284 for a gas Sierra on Ohio's gas.

Questions Toledo drivers ask
How far can a Sierra EV AT4 / Denali go in a Toledo winter?
About 330 miles on a typical January day (27°F) and about the same in the coldest week of the year (around January 19, 26°F on average), estimated from real EV drives at those temperatures. That's 20% below its 410-mile rating, mostly from heating the cabin and the battery. Toledo averages 73 days a year below freezing.
How much does it cost to charge a Sierra EV AT4 / Denali in Toledo?
About $118 a month at home for 38 miles a day, at Ohio's average home electricity rate of 19.4¢/kWh: about 10.2¢ a mile. A gas Sierra on Ohio's average gas ($4.05 a gallon) costs about $284 a month for the same driving.
Can I charge a Sierra EV AT4 / Denali on a regular 120 V outlet in Toledo?
Not at 38 miles a day: a 120 V outlet adds only about 30 miles in 12 hours on an average day (25 in the coldest week). Plan on 240 V, which fills it from 10% in about 17 hours.
Is it greener to drive electric on Toledo's grid?
Yes. Toledo's grid (RFC West) is 19% dirtier than the US average, but a Sierra EV AT4 / Denali charged on it still makes 60% less CO₂ than a gas Sierra.
