Electricity cost in Connecticut

What drives an electric bill in Connecticut

Electricity in Connecticut averages about 28¢/kWh — about 67% above the U.S. average of 16.8¢. Every kilowatt-hour your home uses is billed at that rate, so Connecticut's rate sets the baseline for what every appliance costs to run.

The bill is dominated by high-wattage, long-running loads. In Connecticut, running central AC works out to about $179/month and an electric water heater around $102/month; electric heat and EV charging land in the same tier. Small electronics barely move the needle by comparison — it's the heating, cooling, and water loads that decide a Connecticut bill.

You have two levers. The first is the rate itself — where Connecticut allows supplier or plan choice, shopping it can shave the 28¢ baseline. The second is usage: trimming hours on the biggest draws saves far more than unplugging phone chargers. Enter any appliance in the calculator to see its exact cost at Connecticut's rate.
