Heads up
No competitive provider plans in San Marcos
San Marcos is served by San Marcos Electric Utility, a city-owned 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 San Marcos Electric Utility through public tariff filings, not by a contract you sign with a private provider.
If you've moved here from Houston, Dallas, Fort Worth, or any deregulated Texas city, your old provider doesn't follow you. San Marcos Electric Utility will be your one-and-only provider for as long as you're at this address.
