Wyoming electricity bills in context
Wyoming's average monthly electricity bill is $115, the 47th most expensive of the 50 states and DC. This sits well below the national average of $158, a difference of $43 per month. Wyoming achieves this lower bill through a combination of a below-average electricity rate of 14.02¢/kWh — nearly 4¢/kWh less than the national average of 18.07¢/kWh — and below-average household consumption of 822 kWh per month compared with 876 kWh nationally.
Over the past year through August 2026, the bill rose 2.7% from $112. Looking back five years to August 2021, it has climbed 17.7%, and since December 2008, it has grown 56.6%. Seasonal variation is modest: the peak arrives in January 2026 at $143, while September 2025 saw the lowest bill at $95, a swing of $48.
Among the six bordering states, Wyoming's bill falls in the middle range. Utah's average of $105 is the lowest, followed by Colorado at $114 and Montana at $115, matching Wyoming. Idaho stands at $116, Nebraska at $123, and South Dakota at $141.

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 Wyoming may pay well above or below $115. 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.
