Colorado electricity bills in context
Colorado's average monthly electricity bill is $109 since June 2025, ranking 49th among the 50 states and DC—toward the lower end of what Americans pay. The bill is 30.1% below the national average of $155, a gap driven by both factors. Colorado households use 207 kWh less per month than the national average of 871 kWh, which pulls the bill down. The state's electricity price of 16.35¢/kWh is also 1.49¢/kWh lower than the national rate of 17.84¢/kWh, further reducing costs.
Over the past year to May 2026, Colorado's bill has risen 4.3%, from $104 in June 2025. The growth is steeper over longer spans: since May 2021, the bill has climbed 21%, and since records began in December 2008, it has jumped 57.9%, from $69. Seasonal demand swings the bill significantly. July 2025 saw the peak at $146, while April 2026 brought the lowest month at $90—a spread of $56 around the twelve-month average.
Among neighbouring states, Colorado's $109 bill sits in the middle of the range. Utah costs less at $102 and New Mexico at $98, while Wyoming is slightly higher at $114. Further out, Nebraska reaches $121, Kansas $130, Oklahoma $141, and Arizona $160. Colorado's position reflects both its moderate electricity rates and below-average household consumption.

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 Colorado may pay well above or below $109. 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.
