EV Charge 
Charging a Tesla Model Y at home in Connecticut costs about $67 per 1,000 miles, or $0.067 per mile, at the state’s average residential rate of 24.51¢ per kWh (August 2026). A full charge from empty runs about $22.04.
Connecticut ranks #11 of 51 for electricity prices (1 = most expensive), so this is above the U.S. average of $50 per 1,000 miles for the same car.
