The Houston Weather Bill
See what last month's weather did to a typical Houston home's electricity bill, and what the next 30 days are projected to cost. Compare the market average rate against lower alternatives and find out how much switching could save you.
Over the last 30 days, a typical Houston home used about 1,150 kWh, costing roughly $163 at the market average of 14.2¢/kWh. Looking forward, the next 30 days project to 1,210 kWh ($172). Switching to a 11.9¢/kWh plan would save about $28 next month.

How this estimate is calculated
This calculator uses real daily temperature data from Open-Meteo covering the trailing 30 days, combined with the next 30 days of forward temperature. The first 16 days of the forward window come from Open-Meteo's actual forecast; the remaining days extend that forecast forward using the temperature trend from its final week. Temperatures are converted to cooling degree days (CDD) and heating degree days (HDD) using a 65°F base ??" the standard reference temperature used by the U.S. Energy Information Administration for residential energy modeling.
Forecast skill drops off significantly past about two weeks, so any 30-day temperature projection is directional rather than precise. The trend extrapolation used here is intentionally simple ??" it carries the recent forecast direction forward rather than predicting specific weather events. For estimating bills, what matters most is the broad seasonal direction, which this approach captures.
Houston's electricity demand is overwhelmingly cooling-driven. A typical home's monthly usage is modeled as a fixed baseload (refrigeration, lighting, electronics, standby loads) plus a weather-sensitive component that scales with degree days. The model calibrates this relationship so that an average-weather month produces the baseline usage you specify ??" anchoring the estimate to a real, customizable figure rather than a black-box assumption.
The bill estimate multiplies projected usage by the rate you enter and adds any base or service charge. Real electricity bills include additional components like TDU delivery charges, gross-receipt taxes, and tiered usage credits that vary by plan, so this calculator is a comparison tool ??" not a binding quote. For the same usage, however, the relative savings between two rates is mathematically reliable.
Sources: Temperature data from Open-Meteo's archive and forecast APIs. Degree-day methodology aligns with EIA conventions. Typical Houston residential usage figures reflect EIA Texas state averages, adjusted for the local cooling-dominated climate.
