San Antonio Electricity FAQs

Why can't I choose my electricity provider in San Antonio?

San Antonio opted out of Texas electricity deregulation. CPS Energy is a municipally owned utility (owned by the City of San Antonio), and the city decided to keep it that way rather than open the market to competition. This gives them more local control but means residents can't shop for rates.

Are CPS Energy rates higher than deregulated cities?

Actually, no. CPS Energy's 12-month average of 12.5¢/kWh is lower than Houston's average (16.67¢) and Dallas's average (16.13¢). While the best plans in deregulated cities can be cheaper (9-11¢/kWh), the average person in San Antonio pays competitive rates without having to shop around.

Will San Antonio ever become deregulated?

Unlikely in the near future. CPS Energy provides reliable service at competitive rates, and there hasn't been significant political push to deregulate. The city benefits from revenue generated by CPS Energy, which funds municipal services. Most residents seem satisfied with the current setup.

How do I lower my CPS Energy bill if I can't switch providers?

Focus on energy efficiency: take advantage of CPS Energy's rebate programs for AC tune-ups, smart thermostats, and insulation. Set your thermostat to 78°F in summer. Request a free home energy audit. Consider averaged billing to spread costs evenly throughout the year. These strategies can save 15-25% on your annual electricity costs.
