About San Antonio
What you're shopping for power in.
San Antonio is the second-largest Texas city by population (about 1.5M) and the seat of Bexar County, with a deep military presence (JBSA Lackland, Randolph, Fort Sam Houston), tourism anchored by the Alamo and the River Walk, and a growing biotech and cybersecurity corridor. It's served by CPS Energy, the largest municipal utility in the United States — not by the ERCOT competitive market.
Climate & bill pattern
Hot dry summers with high UV; mild winters with occasional hard freezes. Higher elevation than Houston means less humidity but the same long summer AC season.
CPS Energy uses a tiered residential rate set by the CPS Board (city-appointed) — per-kWh price increases at higher monthly usage. Like Austin, there's no plan-shopping; the lever residents pull is efficiency (HVAC tune-ups, attic radiant barriers, the CPS Casa Verde and Demand Response programs).

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.
