Connecticut vs U.S. average bill
Connecticut's typical residential bill estimate is higher than the U.S. average by $52.65 per month (31.9%).
Is this what you'll actually pay?
It's a fair benchmark, not a forecast. We take Connecticut's average rate of 24.16 ¢/kWh and apply it to 900 kWh a month at the all-in average rate, which comes to $217.44. That rate already includes delivery, fixed charges, and utility fees; locally billed taxes vary by area.
Your own bill can land well above or below that, depending on how much you run the air conditioning, how you heat your home and water, your home's size, and how your utility designs its rates.

What usually moves a household bill?
In practice, the biggest bill drivers are air conditioning, space heating, electric water heating, laundry, EV charging, and the length of time high-wattage appliances run each month.

Rate design is the other half: Eversource (CL&P)'s standard residential tariff adds a $9.62 fixed monthly charge before the first kilowatt-hour. See the itemized charges for Connecticut.
Frequently asked questions
What is the average electric bill in Connecticut?
Connecticut households pay about $217.44 a month ($2609.28 a year) at the state average of 24.16 ¢/kWh, based on 900 kWh of monthly use and the EIA's July 2026 residential data. The rate is all-in: delivery, fixed charges, and utility fees are already inside it; locally billed taxes vary by area.
How does Connecticut compare with the U.S. average electric bill?
The U.S. average bill at 900 kWh is about $164.79 (18.31 ¢/kWh, EIA). Connecticut's $217.44 is about $52.65 a month more — roughly 32% above the U.S. average.
How much is the electric bill for an apartment vs a house in Connecticut?
At Connecticut's average rate, about $159.71 for an apartment (650 kWh), $217.44 for a small home (900 kWh), $286.71 for a medium home (1,200 kWh), $379.08 for a large home (1,600 kWh) per month. Figures for usage other than the benchmark use a two-part model, a fixed monthly charge plus a per-kWh rate, that matches the statewide average exactly at the benchmark usage.
Why is my Connecticut electric bill higher than the average?
Usage is the biggest reason: air conditioning, electric heat, and water heating can push a home far past 900 kWh a month. Rate design matters too. In Connecticut, Eversource (CL&P)'s standard residential tariff carries a $9.62 fixed monthly charge plus 12.03¢/kWh in riders, so a low-usage home pays more per kWh than the average implies and a high-usage home pays less.

Source: U.S. Energy Information Administration (EIA) Retail Sales of Electricity. Updated: July 2026. Estimates use the EIA all-in average residential rate — energy, delivery, fixed charges, and utility fees together, not just the electricity itself. Fees are inside the rate, not an extra on top; how your own bill splits fixed versus per-kWh charges varies by utility.
