Average Electric Bill in Oklahoma
Residential · 12-month average, September 2025 – August 2026.
That works out to about $1,781 a year. Among the 50 states and DC, Oklahoma has the 30th highest average residential bill.
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: 13.78¢/kWh × 1,077 kWh ≈ $148. A state can land high on either factor — Oklahoma pays below the national rate but uses much more 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.

Oklahoma electricity bills in context
Oklahoma's average monthly electricity bill for the twelve months from September 2025 to August 2026 is $148, placing it 30th among the 50 states and DC when counting down from the most expensive. This sits $10 below the national average of $158. The lower bill partly reflects Oklahoma's cheaper electricity rate of 13.78¢/kWh, which is 4.29¢/kWh below the national rate of 18.07¢/kWh. However, Oklahoma residents also use more power than average: 1,077 kWh per month compared to the national average of 876 kWh, which pushes the bill up. Over the past year, the bill has risen 7.2%, from $138 to $148.
Across the full span tracked, the changes have been steeper. Since August 2021, the bill has climbed 29.5%, from $115. Over the longer run since December 2008, it has grown 46.4%, from $101. Seasonally, Oklahoma's electricity bills swing sharply. August 2026 peaked at $251, while November 2025 was lowest at $101, a difference of $150. The twelve-month average of $148 falls between these extremes.
Among Oklahoma's neighbors, bills range widely. New Mexico's average is $101 and Colorado's is $114, both well below Oklahoma's. Kansas and Arkansas average $135 and $143 respectively. Missouri is nearly matched with Oklahoma at $147, while Texas is notably higher at $179.

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 Oklahoma may pay well above or below $148. 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.
