EIA lists it as Public Service Co of Oklahoma.

PSO commercial electricity prices, 2015 to 2025

In 2015 PSO billed its commercial customers an average of 7.04¢ per kWh. In 2025 the figure was 9.15¢, so it rose 30% over 10 years. The average for all commercial customers in Oklahoma rose 18% over the same period. The highest year was 2023, at 10.25¢. Between 2024 and 2025 it rose 4.1%.

Average use and average bill are the utility’s commercial sales and revenue divided by its commercial customers and by twelve. The bill is an all-in figure: energy, delivery, demand and fixed charges together. A few very large customers pull both averages up, so most businesses use and pay less than the average.

Residential, commercial and industrial prices at PSO

In 2025 the average commercial price at PSO was 36% below the residential figure and 46% above the industrial one. Larger customers take power at a higher voltage and use it more steadily, so at most utilities the average falls from residential to commercial to industrial. Which class an account falls in is the utility’s decision, and the line between commercial and industrial is drawn differently from one utility to the next.

How PSO’s commercial rates are set

PSO is investor-owned, so its rates are set in cases before the Oklahoma Corporation Commission and published in a tariff, which is a public document. A commercial account is billed on a rate schedule, chosen by the size of the account and the voltage it takes power at, and a schedule usually combines a fixed monthly charge, a charge per kWh and, above a certain size, a demand charge on the highest rate of draw in the month. The schedule code is printed on the bill. There is no competitive supply market for ordinary commercial accounts in Oklahoma, so the levers are the schedule, the peak and the amount used.

Meters, time-varying rates and net metering at PSO

EIA counts 74,758 commercial meters at PSO in 2025, and 74,744 of them (more than 99%) are advanced meters (AMI), which record use at least hourly and report it to the utility at least daily. Of the rest, 1 are automated-reading (AMR) meters, which send a reading to the utility for billing only, and 13 are standard meters. An advanced meter is what makes interval data possible, and interval data is what shows when a building’s peak demand happens.

At PSO, 65,158 commercial customers were on a time-varying rate in 2025, about 85% of its commercial customers. A time-varying rate charges more in some hours than in others, so when a business uses power matters as well as how much. The kinds PSO reports offering commercial customers are time-of-use pricing.

EIA records 102 commercial net-metered generating systems at PSO in 2025, with 6.96 MW of capacity between them: about 1.3 for every 1,000 commercial customers. Net metering credits a customer for power its own system sends to the grid; the terms are in the utility’s tariff.

How reliable is PSO’s electric service?

PSO customers went without power for an average of 98 minutes in 2025, excluding major storms, with about 1.16 interruptions per customer. The average across U.S. utilities reporting the same way is 124 minutes. With major storms counted the figure was 200 minutes. These are averages over every customer of every class, so they describe the system and not any one street.

Where PSO serves

EIA records PSO serving customers in 46 Oklahoma counties: Atoka, Beckham, Blaine, Caddo, Cherokee, Choctaw, Coal, Comanche, Cotton, Craig, Creek, Custer, Delaware, Dewey, Grady, Greer, Harmon, Haskell, and 28 more. A county can be shared between utilities, so this does not tell you who serves a given address. The utility that serves an address is the one named on its bill.

EIA lists the Southwest Power Pool as its balancing authority. SPP is one of the organised wholesale markets, which run the grid and the wholesale power market across their area.

Other utilities in Oklahoma

The average each billed its commercial customers in 2025. The Oklahoma page has the state’s own figures and every utility with 500 or more commercial customers.

• OG&E (8.02¢)
• Tri-County Electric Cooperative (14.73¢)

What these figures can and cannot tell you

• They are averages over every commercial customer. A utility whose commercial customers are mostly large averages fewer cents per kWh than one serving mostly small shops, so a lower figure can mean larger customers and not a lower rate.
• They are not a rate schedule. None of these figures is a charge printed in PSO’s tariff, and nothing here works out a bill from one. The tariff index lists the utilities whose filed schedules are quoted on this site.
• They are annual and final. EIA publishes utility figures once a year. The Oklahoma page carries the state’s trailing 12 months, which is more recent and still preliminary.

For one building, the cost estimator gives a range by building type, size and state, and price by utility sets every utility side by side. Commercial vs residential vs industrial compares the classes in every state.

Common questions about PSO

What is the average commercial electricity rate at PSO?

PSO billed its commercial customers in Oklahoma an average of 9.15¢ per kWh in 2025, according to the U.S. Energy Information Administration. That is 0.7% above the Oklahoma commercial average of 9.09¢. It is the utility’s commercial revenue divided by its commercial sales, so it describes the whole class and is not the rate on any one schedule.

How much is the average commercial electric bill at PSO?

About $714 a month in 2025, on average use of about 7,802 kWh a month. That is PSO’s commercial revenue divided by its 76,872 commercial customers. A few very large accounts pull the average up, so most businesses pay less than this.

Have PSO’s commercial electricity rates gone up?

The average PSO billed commercial customers rose 30% between 2015 and 2025, from 7.04¢ to 9.15¢ per kWh. The Oklahoma commercial average rose 18% over the same period.

How reliable is PSO’s electric service?

PSO customers averaged 98 minutes without power in 2025, excluding major storms, against a 124-minute average for U.S. utilities reporting the same way (EIA).

Does PSO use smart meters for businesses?

EIA counts 74,744 advanced (AMI) meters among PSO’s 74,758 commercial meters in 2025, which is more than 99%. An advanced meter records use at least hourly, which is what makes interval data and time-varying rates possible.

Is this the rate my business will pay PSO?

No. It is an average over every commercial customer, from a corner shop to a campus. What one business pays depends on its rate schedule, how much it uses and how hard it draws at its peak. The schedule code is printed on the bill, and the schedule itself is in PSO’s tariff.
