Electricity prices nearby

EIA lists AEP Texas Central in this county. Where Lockhart is on AEP Texas Central's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Lockhart 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 1,490 kWh at $228 per kW a year, plain multiplication and not a savings estimate or an offer.

Scale the Lockhart 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 $229 per kW a year as plain multiplication.
