What's different about dedicated circuits in San Antonio
Other dedicated circuits often added here include pool pumps and heaters, outdoor kitchens, garage freezers and mini-splits for converted garages or casitas. Each needs the right wire size, breaker and, outdoors, GFCI protection and weather-rated equipment. Permits come from the City of San Antonio Development Services Department for work inside city limits.
Older central-city homes often have small services and wiring from several eras, while 1950s and 1960s ranches may have 100 amp panels with little spare space. North-side growth brings EV chargers, pools and outdoor kitchens that add load.
Weather and the utility in San Antonio
San Antonio summers are long and hot, often with weeks of triple-digit afternoons, and air conditioners rarely get a break from May to October. Spring brings hail and severe thunderstorms, and the February 2021 winter storm caused rolling and extended outages across the city. Unlike Houston and Dallas, San Antonio is not in Texas's deregulated retail market: CPS Energy, the city-owned utility, sells the power and owns the lines and meters, so service upgrades, solar interconnection and reconnection all go through one utility. CPS Energy has offered solar and efficiency rebates that change from year to year, so check before you plan.
