Each utility’s current residential tariffs, transcribed from its tariff sheets, with periods, tiers, fixed charge and a typical bill. Customer counts from EIA-861 (2025).
Each row prices a utility’s standard plan for a typical home. The Oklahoma average of 13.81¢/kWh (EIA, 12 months) is what every household in the state actually paid, including utilities not modeled here and discounted low-income bills, so it can sit below every row.
Prices include PSO's interim base-rate increase billed since July 2026, which is subject to refund until the rate case is decided.

Charging an electric car in Oklahoma
Driving a Tesla Model Y Long Range AWD 1,000 miles a month takes 275 kWh from the wall (EPA 27.5 kWh/100 mi), about $38 at the state average. A 25.5 mpg gasoline car covering the same distance at $4.17 a gallon (Midwest (PADD 2) average, October 2026) costs about $163.
Some utilities, such as PSO, sell EV plans with cheaper overnight hours. The table shows, for each utility, the plan with the lowest total bill for a typical Oklahoma home that adds 1,000 EV miles a month, averaged over the year, and what plugging in at 6 pm would cost instead.
Over the last 12 months the average price was 13.81¢ per kWh and the average home used 1,075 kWh a month, so a typical Oklahoma household spent about $148 a month on electricity, or $1,781 a year. Use is 23% above the US average of 875 kWh a month, peaking in August at 1,696 kWh.
The state average hides the real spread. Utilities in the same state charge different prices, and on a time-of-use plan the same kWh costs more in the peak hours than off-peak; each utility page shows by how much. Open OG&E’s page to see its plans, prices by hour and fixed charge, or run the calculators below with Oklahoma preloaded.
Natural gas for homes averaged $1.85 per therm over the 12 months to August 2026 (EIA, all charges included), and a typical gas-heated home uses about 450 therms a year for heating. The heat pump calculator compares that with electric heating on your plan.
A south-facing, 20° rooftop array in Oklahoma produces about 1,511 kWh per installed kW a year (NREL PVWatts at the state’s population center). What that is worth depends on your utility’s export rule, shown on each utility’s page.
