Average Electric Bill in Colorado
Residential · 12-month average, September 2025 – August 2026.
That works out to about $1,371 a year. Among the 50 states and DC, Colorado has the 49th highest average residential bill.
EIA withheld residential sales for Colorado in May 2026, so usage for that month is calculated from EIA's revenue and price.
Data current through August 2026 — the latest available from the U.S. EIA, which publishes monthly figures on a roughly two-month delay.
What makes up the bill
Price × usage = bill, exactly: 16.67¢/kWh × 685 kWh ≈ $114. A state can land high on either factor — Colorado is below the U.S. average on both.

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.

Colorado electricity bills in context
The average monthly electricity bill in Colorado is $114, ranking it 49th among the 50 states and DC, with only Utah and New Mexico lower. This bill rests on a price of 16.67¢/kWh and usage of 685 kWh per month. Over the twelve months from September 2025 to August 2026, the bill has risen 8.2% from $106 in the prior year.
Colorado's bill sits well below the national average of $158, a gap of $44 per month. Two factors drive this: the state's households use 191 kWh less monthly than the national average, and electricity itself costs 1.40¢/kWh less. Both push the total downward. Within the region, only New Mexico and Utah pay less, while all other bordering states—Arizona, Oklahoma, Kansas, Nebraska, and Wyoming—pay more.
Over the longer term, the bill has climbed steeply. Since August 2021 it has risen 25.3%, and since December 2008 it has increased 66%. Seasonally, the bill swings from a low of $90 in April 2026 to a peak of $174 in July 2026, a span of $84 around the twelve-month average of $114.

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 Colorado may pay well above or below $114. 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.
