Retail choiceRegulated: your utility sets the rate

You cannot shop for supply in Oklahoma

Oklahoma is a regulated market. Your utility is your only option for supply, and the rate is set through a public commission process rather than by competition. Pricing tends to be more stable than in deregulated states, and there is no switching decision to make.

That makes the levers on your side of the meter the only ones available: what you run, for how long, and whether you generate any of it yourself.

What this rate means for solar in Oklahoma

At 13.38 cents, Oklahoma has some of the cheapest electricity in the country, which cuts both ways. Bills are lower, and so is the value of every kilowatt-hour a solar array offsets. Payback periods here are longer than the national marketing figures suggest, and the case usually rests on incentives, net metering rules and how much sun the site actually gets.

Typical peak sun hours across the South Central region run around 4.5 to 5.5 hours a day as an annual average, though the spread within a region can be wide. For a figure based on your actual location rather than a regional band, use the location-based solar production calculator, and the solar payback calculator for the financial side.

Work out your own numbers

Costs on this page use a national average residential rate of 18.44¢ per kWh (August 2026, EIA-derived state residential averages). Your own rate is printed on your electricity bill and is the number that actually matters. Every figure here is recalculated from one central rate setting, so these tables move when the national average moves.
