CPS Energy Solar, Net Metering & Rates

CPS Energy customer-owned solar first serves the home, while surplus power can flow to the utility and billing or Net Electric Generation credits are determined under the applicable CPS Energy rate and rider.

What homeowners should know

  • Residential systems require the CPS Energy interconnection process before normal parallel operation.
  • The utility's solar billing materials distinguish power supplied by CPS Energy from surplus solar returned to the grid.
  • Net Electric Generation credits are calculated under the applicable rate and rider rather than assumed to equal every component of the retail bill.
  • CPS Energy recommends comparing multiple registered solar contractors before purchasing a system.

Important: Utility tariffs change. Confirm the current rate schedule, interconnection agreement and export-compensation rules for your exact account before signing a solar proposal.

Texas electricity and solar context

State residential benchmark16.11¢/kWh
State planning solar yield1,480 kWh/kW
Benchmark sourceYear-to-date through June 2026

The state electricity-rate figure is a statewide EIA benchmark, not the utility tariff on your bill. Utility plans can differ because of time-of-use periods, tiers, fixed charges, riders, supply choice and solar-export treatment.

Official CPS Energy solar sources

Home Solar Atlas summarizes homeowner-facing rules but treats the utility's current tariff and interconnection documents as the controlling source.

Before you compare installer quotes

  • Use 12 months of actual electricity consumption rather than only your average bill.
  • Ask the installer which utility rate plan and export-compensation schedule the savings model assumes.
  • Separate self-consumed solar value from exported-energy value if the utility uses net billing.
  • For time-of-use tariffs, compare when the home imports energy with when solar exports occur.
  • Model battery economics separately instead of assuming every exported solar kWh has retail value.
