CPS Energy

CPS Energy serves customers in San Antonio in Texas with a residential electricity rate of $0.12 per kWh. This is 29% below the national average of $0.168/kWh, though solar still delivers strong returns with today’s lower installation prices.

At current rates, a typical CPS Energy household using 900 kWh per month spends approximately $1,296 per year on electricity. An 8 kW solar system can offset most or all of that usage, saving an estimated $1,152 annually and $42,001 over the 25-year life of the system. The estimated payback period is 19.3 years.

As a municipal utility, CPS Energy sets its own rates and policies independently. CPS Energy offers net metering, allowing solar customers to receive credits for excess energy sent back to the grid. Heat pump rebates of up to $850 are also available.

The federal residential solar tax credit (Section 25D) expired at the end of 2025. State and utility-level incentives are now the primary financial benefits for homeowners going solar. NuWatt Energy handles the entire process from system design through permits and CPS Energy interconnection, ensuring you receive every available rebate.
