How much does it cost to charge an EV at home in Connecticut?

Data checked October 2026

Short answer

Charging an EV at home in Connecticut costs about $74.17 a month for 1,000 miles in a Tesla Model Y Long Range AWD — 7.4¢ a mile, versus 15.6¢ for a 27.2 mpg car on $4.25 gas.

Connecticut pays 27.47¢/kWh on average for Jan–Aug 2026 — 51% above the U.S. average of 18.19¢, the 7th most expensive of the 50 states and DC.
Regular gasoline averaged $4.25/gal in the New England (PADD 1A) region (EIA, week of Oct 19, 2026), so home charging saves about $985 a year at 12,000 miles.
Efficiency matters as much as price: a Tesla Model Y Standard RWD (24 kWh/100 mi) costs $65.93 a month here, a Ford F-150 Lightning ER (48) $131.86.
Ask your utility about a time-of-use or EV rate: overnight energy is often priced well below the average shown here.
270 kWh a month is 38% on top of the 705 kWh an average Connecticut home used each month in 2025.

The new clean vehicle credit (30D) ended for vehicles acquired after Sept 30, 2025, and the home charger credit (30C) for chargers placed in service after June 30, 2026. Check your utility for charger rebates and EV rates.

How to cut it

Set the car or charger to start after your utility's peak window (often 4–9 pm); on an EV or time-of-use plan that is the cheapest single change.
A Level 2 charger idles at about 7 W — roughly 60 kWh a year.
Cold weather and highway speeds raise kWh per mile; the EPA figure is a combined average.
