What Connecticut Residents Should Know

Home charging is where EV owners in Connecticut see the biggest savings. At the state average of $0.268 per kWh, a Level 2 home charger costs roughly $0.08 per mile. Compare that to $0.11 per mile for a 30-mpg gas car fueled at $3.40 per gallon, and you are looking at roughly $33 in monthly savings if you drive about 1,000 miles.

Connecticut utilities with time-of-use plans offer off-peak rates as low as $0.180 per kWh. Scheduling your charge for overnight hours drops the cost to just $0.05 per mile. Public DC fast chargers, on the other hand, typically cost $0.30–$0.50 per kWh and should be reserved for road trips rather than everyday charging to keep costs down.

Connecticut households currently pay an average of $192 per month for electricity. Adding an EV to the household typically raises the bill by $80–$107 per month (for 1,000–1,300 miles of driving), which is still far less than the $112–$146 per month you would spend on gasoline for the same distance. Use the calculator above to enter your exact driving habits and see how much you could save.

Choosing a charging setup matters too. A standard 120-volt outlet (Level 1) adds only 3–5 miles of range per hour, which is fine for low-mileage drivers, while a 240-volt Level 2 charger refills most EVs overnight. A home Level 2 charger runs about $500–$1,200 installed and, at Connecticut's savings versus gasoline, usually pays for itself within a year or two of everyday driving.
