What's different about whole-home surge protection in San Antonio
The electrician should check grounding and bonding, especially in older homes in neighborhoods such as Alamo Heights and Monte Vista. CPS Energy, the city-owned utility, owns the meter and service. Surge protection reduces damage from common surges but cannot guarantee protection from a direct strike.
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.
- Permits in San Antonio
- Inside city limits, electrical permits come from the City of San Antonio Development Services Department; suburban cities issue their own. Texas electricians are licensed by TDLR, and homes in historic districts may need design review for exterior changes.
