What makes up the bill
Price × usage = bill, exactly: 28.60¢/kWh × 709 kWh ≈ $203. 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 $203, the third highest among the 50 states and DC. This exceeds the national average of $155 by $48, or 30.5%. The gap stems from two forces working in opposite directions. Homes here use 162 kWh less per month than the national average, which pulls the bill down, but the price of 28.60¢/kWh is 10.76¢/kWh above the national rate of 17.84¢/kWh, which pushes it sharply up. The higher rate dominates, leaving Connecticut residents paying substantially more.
Over the past year, the monthly bill has fallen 3.6%, from $210 in the prior period. Over the longer run, growth has been steep: the bill was $161 since May 2021, a rise of 25.8%, and $143 since December 2008, a rise of 42.1%. Neighbouring states show Connecticut's position clearly. Massachusetts averages $183 per month, Rhode Island $165, and New York $164, all notably lower than Connecticut's $203.
Seasonality is pronounced. The peak falls in July 2025 at $282, while the lowest month is October 2025 at $146, a swing of $136. The twelve-month average of $203 sits between these extremes, representing total annual bills of $2,436.

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 (June 2025 – May 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 $203. 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.
