EV Charge A Tesla Model 3 owner in Connecticut pays about $73 in electricity per 1,000 miles when charging at home, based on 24.51¢ per kWh, the EIA’s latest state average (August 2026). That’s $0.073 per mile and about $22.41 for a full charge.
Connecticut ranks #11 of 51 for electricity prices (1 = most expensive), so this is above the U.S. average of $54 per 1,000 miles for the same car. A 30-mpg gas car would spend about $144 on fuel for those 1,000 miles at Connecticut’s $4.33 a gallon, so home charging saves roughly $72 every 1,000 miles.
