Why Oklahoma pays what it pays
Oklahoma sits on top of both its fuels. It is a major natural gas producer, so gas reaches its power plants without long-haul transport cost, and it has one of the strongest wind resources in North America with a large installed fleet. Those two resources cover most of the state's generation between them.
The state also avoids most of the cost drivers that raise rates elsewhere. There is no renewable mandate, no early-retirement schedule, limited wildfire mitigation obligation, and a flat, inexpensive distribution geography.
The one significant recent event was the February 2021 winter storm, which produced extraordinary gas costs. Oklahoma responded by securitising them, issuing bonds to spread the cost over many years rather than putting it on one bill. That is why a very large one-time cost appears as a small, long-lived surcharge instead.
Where Oklahoma power comes from
Oklahoma generated 91 TWh in 2025, the 18th largest output of any state. Natural gas supplied 44.7% of it. Renewables accounted for 44.8%, against 23.8% nationally, which ranks Oklahoma #12 of 51.
- Natural gas 44.7% 41 TWh
- Wind 41.8% 38 TWh
- Coal 10.4% 9 TWh
- Hydroelectric 1.9% 2 TWh
- Solar 0.8% 723 GWh

Heating in Oklahoma: gas, heat pump or resistance
Residential natural gas in Oklahoma averaged $13.99 per thousand cubic feet in 2024, about $1.35 per therm, against a national average of $14.50. Put on the same scale as the state's electricity rate, the cost of delivering one million BTU of heat works out as follows.
In Oklahoma, a heat pump is cheaper to run than a gas furnace by about $1.92 per million BTU at these assumptions. Over a 60 million BTU heating season that is roughly $115, before counting the cooling a heat pump also provides.

What each Oklahoma utility charges
The statewide average hides a wide spread. Across the 32 Oklahoma utilities reporting to the EIA, rates run from 9.09¢ at Southeastern Electric Coop Inc to 15.87¢ at Tri-County Electric Coop, Inc (OK) . Together they serve 1.8 million residential customers.

Who sells electricity in Oklahoma
Oklahoma Gas and Electric serves the Oklahoma City area and much of the centre. Public Service Company of Oklahoma, an AEP company, serves Tulsa and the northeast, and co-operatives serve most of the state's land area.
There is no residential retail choice. The Oklahoma Corporation Commission, whose three members are elected statewide, sets rates.
Oklahoma sits in The Great Plains. An outstanding wind resource, cheap in-state gas, and the only state in the country with no investor-owned utility. Read the regional analysis.
What you can actually do about it
Oklahoma's securitisation surcharge runs for years and is a fixed component of the bill. It cannot be avoided by reducing usage, so factor it in separately when you model savings.
Both major utilities offer variable peak pricing plans with large off-peak discounts. In a state with severe summer afternoon peaks, shifting cooling load is the main saving available.

Oklahoma electricity rates: common questions
What is the average electricity rate in Oklahoma?
The average residential electricity rate in Oklahoma is 13.38 cents per kilowatt-hour as of May 2026, according to the U.S. Energy Information Administration. That is -27.4% relative to the national average of 18.44¢/kWh.
How much is the average monthly electric bill in Oklahoma?
The average Oklahoma household paid $141 a month across the twelve months to May 2026, using an average of 1,043 kWh. That is -9.3% against the U.S. average bill of $155, and it ranks 31st highest of the 51 jurisdictions. Your own bill depends on the size of your home, your heating and cooling equipment and your rate schedule.
Why is the Oklahoma bill ranking different from its rate ranking?
A bill is the rate multiplied by usage, and usage varies between states more than price does. Oklahoma ranks #49 of 51 on price but 31st on the actual bill, because households there use about 1,043 kWh a month against a national average of 871. Climate and heating fuel drive most of that difference.
Have electricity rates in Oklahoma gone up?
Oklahoma rates rose 3.4% over the year to May 2026, from 12.94¢ in May 2025 to 13.38¢.
Can I choose my electricity supplier in Oklahoma?
Regulated monopoly. Oklahoma households buy both supply and delivery from their local regulated utility or co-operative; there is no competitive residential supplier market.
