That works out to about $2,313 a year. Among the 50 states and DC, Connecticut has the 3rd highest average residential bill.

What makes up the bill
Price × usage = bill, exactly: 27.44¢/kWh × 703 kWh ≈ $193. A state can land high on either factor — Connecticut pays well above the national rate but uses less power than average.

Trend since 2008
Each point is a trailing 12-month average, which strips out the summer/winter swing and leaves the underlying trend. Bills start in January 2008 because that is when EIA began reporting customer counts.

Connecticut electricity bills in context
Connecticut's average monthly electricity bill is $193, the third highest in the 50 states and DC. The bill runs well above the national average of $158, a difference of $35 per month. The state's price of 27.44¢/kWh is substantially higher than the national rate of 18.07¢/kWh, driving the bill up despite residential usage running below the national average at 703 kWh per month against 876 kWh nationally.
Over the past year, the average bill has fallen 8.5% from $211 in the prior twelve-month period. Over the longer run, the picture is different: since August 2021, the bill has risen 24.2% from $155, and since December 2008 it has climbed 35% from $143. The seasonal swing is marked, with January 2026 reaching a peak of $245 and October 2025 dropping to $146, a span of $99 within the twelve-month window.
Among neighbouring states, Connecticut's bill exceeds those of Massachusetts at $184, New York at $168, and Rhode Island at $163, all three of which also run above the national average but leave Connecticut the costliest of its regional peers.

How this is calculated
EIA’s retail-sales dataset reports, for every state and month, total residential revenue and the number of residential customers served. The average monthly bill is simply the first divided by the second — total spending across all households, spread evenly over all accounts.
bill = revenue ÷ customers · averaged over 12 months (September 2025 – August 2026)
Two caveats worth knowing. It is an average, so it blends apartments with large houses — a typical household in Connecticut may pay well above or below $193. And it counts what was actually billed for electricity, including fixed service charges, so it is not the same as multiplying your own usage by the advertised rate.
