Running cost comes down to wattage, hours and your rate. In Texas the rate is 16.44 cents per kWh, which is 10.8 percent below the national average. Here is what that means for a electric oven.
A electric oven drawing 2,400 W costs $0.39 per hour in Texas. Run 1 hours a day that is $0.39 daily, $11.84 a month and $144 a year, which is $17.52 less than the same appliance at the US average rate.

Find the row matching the nameplate on your own unit. Within a single appliance category the spread is often wider than the difference between categories, so the label is worth reading.
What this means in Texas
This appliance runs on much the same schedule regardless of climate, so the figure above is a reasonable year-round estimate for Texas. What changes it is your own usage pattern rather than the weather.
Why Texas pays what it does
Texas has a competitive retail electricity market, so the rate used here blends households on the utility default with households on shopped supply plans. If you have never switched supplier you are probably on the default, which is usually the more expensive side of that blend. Only the generation portion of your bill changes when you switch; delivery and outage response do not.
At 16.44 cents, Texas ranks 27 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.

| Utah | 12.96¢ | $9.33 | $114 |
| Texas | 16.44¢ | $11.84 | $144 |
| California | 33.25¢ | $23.94 | $291 |

Lowering the number in Texas
- Skip preheating for anything that is not baked goods. Roasts and casseroles do not need it.
- Use a countertop oven or air fryer for small meals. Heating a small cavity costs far less than a full oven.
- Do not open the door to check. Each opening dumps a large share of the heat.
- Cook in batches while it is hot. The expensive part is getting to temperature.
- Use residual heat. Switch off a few minutes early and let the mass finish the job.
Offsetting it with solar in Texas
This load uses about 2.40 kWh a day. Covering that would take roughly 2 standard 400 W panels at typical sun hours, an array of about 0.80 kW. Because it offsets electricity worth 16.44 cents rather than the national 18.44 cents, the same array is worth less here than the national payback figures suggest.
An oven is a large resistive load for a short period. Cooking at midday on a sunny day is realistic; cooking at 7pm off a battery is expensive. Full sizing, including battery and inverter requirements, is on the solar sizing page for this appliance.
