What does it cost to charge an EV in Connecticut?
At Connecticut’s average electricity rate of 27.7¢/kWh, a typical driver (13,500 mi/yr, mostly home charging) spends about $1,258 a year — roughly 9.3¢ per mile, and around $392 less than the same miles in a 27 MPG gas car. Run your own numbers below.

Why Connecticut charging costs what it does
Connecticut homes pay about 27.7¢/kWh, which is 9.0¢ above the US average. Because home electricity is the main driver of EV running cost, that puts Connecticut drivers toward the pricier end for charging. Charging more at home (versus public fast-charging at $0.40–0.50/kWh) lowers it further.

Cut it further with solar
If you charge at home, your EV runs on whatever your roof or the grid supplies. Pairing an EV with rooftop solar can drop your effective charging cost well below the grid rate — see whether that maths works where you live with our Connecticut solar payback calculator.
