San Antonio commercial electricity at a glance
San Antonio businesses buy electricity from CPS Energy, which serves San Antonio as a regulated utility without retail supplier choice. That means there is no supplier contract to shop here, and no broker can change the rate. For market context, the average Texas commercial account paid 8.66¢ per kWh all-in (EIA, 06/2026). A business with locations in deregulated Texas territory can still shop those accounts.
San Antonio is in Bexar County, South Texas. San Antonio is served by CPS Energy, the city-owned utility, so San Antonio businesses buy on CPS Energy's commercial tariffs and cannot shop a retail supplier; a company with locations in deregulated Texas territory (Houston, Dallas and Fort Worth, the Coastal Bend, the Rio Grande Valley) can shop those accounts.
Voltcheckr LLC, PUCT Broker Registration BR260102. A registered independent electricity broker, not an energy supplier. Your contract is with the supplier you choose, and that supplier pays our commission; you pay Voltcheckr nothing.
No. San Antonio is served by CPS Energy, a regulated utility without retail supplier choice, so there is no supplier contract to shop. Rates are set through the utility's own tariff process, not by a retail supplier's contract.
Ask CPS Energy which commercial tariff and demand structure your account is on, since a rate-class change or a demand-management step can lower a bill where a supplier switch cannot. A business with other locations in deregulated Texas territory can shop those accounts through Voltcheckr.
Not for San Antonio accounts on CPS Energy. Voltcheckr LLC is a PUCT-registered electricity broker (BR260102) for the deregulated ERCOT markets, and we help San Antonio companies with locations elsewhere in Texas.
