No competitive REP plans in San Antonio
San Antonio is served by CPS Energy, a regulated municipal utility — not by the deregulated retail market that powers most of Texas. That means you can't shop for a competitive electricity provider here. Rates are set by CPS Energy through public tariff filings, not by a contract you sign with a private REP.
If you've moved here from Houston, Dallas, Fort Worth, or any deregulated Texas city, your old REP doesn't follow you. CPS Energy will be your one-and-only provider for as long as you're at this address.
