Against San Antonio

The nearest of the six largest modeled places is San Antonio, 33 km to the northeast, at 1,505 kWh per kW. LaCoste models 22 kWh per kW (1.5%) above it. At 0.15 degrees of latitude apart, the two sit at almost the same sun angle, so geometry explains little. The two weather stations sit a similar distance from their points (2.4 km and 2.2 km), so station distance does little to explain the gap, and the weather record does the rest.

The second-nearest large place is Austin, 150 km northeast, where the same model gives 1,483 kWh per kW, so LaCoste runs 44 above that figure. Against the Texas median place month by month, LaCoste runs at least 2% higher in February, August, October, November. It runs at least 2% lower in April, May, September, December.

Electricity in Medina CountyEIA-861

Electricity prices nearby

EIA lists AEP Texas Central in this county. Where LaCoste is on AEP Texas Central's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of LaCoste may instead be served by a co-op or utility listed below, which sets its own rates; check your bill. For scale only, the median 2025 average price across the 60 Texas retail providers on this site is 15.32¢ per kWh, which would put the modeled 1,527 kWh at $234 per kW a year, plain multiplication and not a savings estimate or an offer.

Also listed in the county

• City of San Antonio: 12.4¢ per kWh, a bundled average, 888,946 residential customers across 8 counties.
• Bandera Electric Coop, Inc: 12.77¢ per kWh, a bundled average, 35,906 residential customers across 7 counties.
• Medina Electric Coop, Inc: 12.54¢ per kWh, a bundled average, 30,778 residential customers across 17 counties.
• AEP Texas Central Company: 5.91¢ per kWh, delivery charges only, before the retail energy price, 793,896 residential customers across 44 counties.

These utilities serve other parts of the county, which can include parts of LaCoste. They are the largest bundled providers, and the largest delivery-only one, whose EIA service territory lists the county. A county can list several, and which one serves a street depends on the address, so check your bill.

Size the array, see the kWh.

Scale the LaCoste model to another array size, take off extra losses for shade or dirt, and price the energy at any rate. It is arithmetic on the PVWatts output above, nothing more: not a quote, not a savings estimate and not advice.

Starting rate: the Texas residential average of 15.4¢ per kWh. At that rate the modeled output is worth $235 per kW a year as plain multiplication.
