How much does it cost to charge an electric car in Connecticut?
Power is expensive in Connecticut: 29.4¢ per kWh is 84% above the national average, so time-of-use rates and overnight charging matter more here than almost anywhere. Gas is relatively cheap at about $3.15 a gallon (10% below the $3.50 reference), so a thrifty gas car stays more competitive.
At Connecticut's average rate, adding 100 miles to a Model 3 costs about $7.35 at home, and a full 60 kWh charge costs about $17.64. Over a year of 13,500 miles with 85% home charging, the EV charging cost in Connecticut comes to about $1,071 — roughly $89 a month. The U.S. average for the same car is $687.

Is an electric car worth it in Connecticut?
Connecticut ranks #48 of 50 for EV fuel savings, near the bottom, so the case rests more on driving a lot, charging at home overnight and lower maintenance. For the Model 3 to cost the same to fuel as a Camry, gas in Connecticut would have to drop to about $2.54 a gallon. Add lower upkeep — no oil changes and less brake wear — and the yearly gap typically grows by a few hundred dollars. Whether the switch pays off depends mostly on the price difference you pay up front; enter it in the payback field above.
