Running cost comes down to wattage, hours and your rate. In Oklahoma the rate is 13.38 cents per kWh, which is 27.4 percent below the national average. Here is what that means for a pool pump.
A pool pump drawing 1,500 W costs $0.20 per hour in Oklahoma. Run 8 hours a day that is $1.61 daily, $48.17 a month and $586 a year, which is $222 less than the same appliance at the US average rate.

Pool season in Oklahoma
Pools run year-round or close to it in much of Oklahoma, so the annual figure above is realistic rather than theoretical. That also makes a variable-speed pump upgrade pay back faster here than anywhere else, often inside two seasons.
Why Oklahoma pays what it does
Oklahoma is a regulated market, so your utility is the only supplier and the rate is set through the state commission rather than by competition. Pricing tends to be steadier than in deregulated states, and there is no switching decision available. The levers are all on your side of the meter.
At 13.38 cents, Oklahoma ranks 3 of 51 from cheapest to most expensive. The South Central regional average is 14.73 cents. Roughly half of any residential bill is transmission and distribution rather than generation, which is why rates keep climbing even when fuel prices fall.
How this compares across the country
The same pool pump on the same schedule, in the cheapest and dearest states:
| State | Rate | Per month | Per year |
|---|---|---|---|
| Idaho | 12.35¢ | $44.46 | $541 |
| Utah | 12.96¢ | $46.66 | $568 |
| Oklahoma | 13.38¢ | $48.17 | $586 |
| California | 33.25¢ | $120 | $1,456 |
| Hawaii | 52.00¢ | $187 | $2,278 |
Lowering the number in Oklahoma
- Work out your actual turnover requirement. Many pumps are scheduled for eight or twelve hours when four would filter the volume.
- Reduce runtime in steps. Cut an hour, watch the water a week, cut another.
- Switch to variable speed. Power rises with the cube of flow, so slower for longer moves the same water for roughly a quarter of the energy.
- Keep skimmer and pump baskets clear. A restricted intake makes the motor fight pressure it should not see.
- Run off-peak if you are on a time-of-use plan. Nobody cares when a pool pump runs.
Offsetting it with solar in Oklahoma
This load uses about 12.00 kWh a day. Covering that would take roughly 9 standard 400 W panels at typical sun hours, an array of about 3.60 kW. Because it offsets electricity worth 13.38 cents rather than the national 18.44 cents, the same array is worth less here than the national payback figures suggest.
Pool pumps are the ideal solar load: large, daytime, and completely flexible about timing. Variable-speed pumps make the match better still. Full sizing, including battery and inverter requirements, is on the solar sizing page for this appliance.
