What this means in Connecticut
At 24.32 cents per kWh, Connecticut is 4.90 cents above the national average. The same Lucid Air that costs $23.60 to fill here costs $12.72 in Nevada and $51.15 in Hawaii.
Connecticut is one of the places where the sum does not always favour electricity. 1 of these 50 cars cost more per mile than a 30 mpg petrol equivalent at the flat residential rate. The efficient end of the range still wins comfortably — the Lucid Air saves about $960 a year — but a large electric truck here is not a running-cost decision.
These are flat residential averages. Most utilities offer a time-of-use plan where overnight charging costs considerably less, and public fast charging costs considerably more. Each vehicle page lets you enter your own rate.
