Charging at home at South Carolina's average rate (15.5¢/kWh) costs about $99 a month for 38 miles a day, against $279 for a gas Sierra on the Lower Atlantic's gas.

Questions Greenville drivers ask
How far can a Sierra EV go in a Greenville winter?
Greenville's winters are mild: about 367 miles on a typical January day (44°F) and about the same in the coldest week (around January 10, 44°F), estimated from real EV drives at those temperatures. That's within 6% of its 390-mile rating.
How much does it cost to charge a Sierra EV in Greenville?
About $99 a month at home for 38 miles a day, at South Carolina's average home electricity rate of 15.5¢/kWh: about 8.6¢ a mile. A gas Sierra on the Lower Atlantic's average gas ($3.86 a gallon) costs about $279 a month for the same driving.
Can I charge a Sierra EV on a regular 120 V outlet in Greenville?
Not at 38 miles a day: a 120 V outlet adds only about 29 miles in 12 hours on an average day (28 in the coldest week). Plan on 240 V, which fills it from 10% in about 10 hours.
Is it greener to drive electric on Greenville's grid?
Yes, more than most places. Greenville's grid (SERC Virginia/Carolina) is 23% cleaner than the US average, so a Sierra EV charged on it makes 73% less CO₂ than a gas Sierra.
