EV Charger Installation · Texas
A Level 2 home charger needs a 240 volt circuit, usually 40 to 60 amps, run from your panel to the garage or driveway. The electrician checks whether your service can carry the load, pulls the permit and installs either a hardwired charger or a NEMA 14-50 outlet.
Heat, hail and the 2021 winter storm have made generators, surge protection and panel capacity priorities; electricians are licensed by the state through TDLR.
Across the South Central, homes deal with long, hot summers, severe storms and occasional hard freezes. Permit offices, utilities and housing stock differ by city, which affects how ev charger installation is planned and scheduled. These local guides cover the Texas cities where we have written specific notes.
San Antonio's newer subdivisions on the north side and in Stone Oak mostly have attached garages, which makes a Level 2 charger straightforward, while older homes in Monte Vista and Alamo Heights may have detached garages or carports. Many homes already run a large AC system and sometimes a pool, so a load calculation decides whether a 40 or 48 amp charger fits.
Utility: CPS Energy (city-owned)
Austin has a large and growing number of electric vehicles, and Level 2 home chargers are among the most common electrical requests. In older central homes, the panel is often on the opposite side of the house from the driveway, so circuit length and routing drive the cost.
Utility: Austin Energy (city-owned)
Fort Worth's newer subdivisions in north Fort Worth, Keller and Benbrook mostly have attached garages, which makes a Level 2 charger straightforward, while older homes in Fairmount and Arlington Heights may have detached garages off alleys. Hail is frequent, so a garage location is better than an outdoor wall.
Utility: Oncor (lines and meters); retail provider of your choice
El Paso's newer subdivisions on the east and west sides mostly have attached garages, which makes a Level 2 charger straightforward, while older homes in Sunset Heights and Kern Place may have carports or detached garages. Desert heat makes garages very hot in summer, so a charger rated for high temperatures helps.
Utility: El Paso Electric (not on the ERCOT grid; no retail choice)
Denton's new subdivisions in every direction mostly have attached garages and 200 amp services, so a Level 2 charger is usually simple, while older homes near downtown may have carports or detached garages and smaller panels. Spring hail makes a garage location better than an outdoor wall.
Utility: Denton Municipal Electric (city-owned)
Waco sits midway between Dallas and Austin on I-35, and many residents commute or travel regularly, so a home Level 2 charger is practical for an electric car. Newer homes in Hewitt and Woodway usually have attached garages, while older homes near Baylor may have carports or detached garages.
Utility: Oncor (lines and meters); retail provider of your choice
Plano has a high rate of EV ownership, and most homes have attached two- or three-car garages that make a Level 2 charger straightforward. Homes already running a large AC system and a pool may need a load calculation and a lower charger setting, and two-EV households often use power sharing.

Not always. A load calculation shows whether the existing service can carry the charger; load management devices can avoid an upgrade in some homes.
Hardwired is often preferred for higher amperage and outdoor locations. A plug-in charger on a NEMA 14-50 outlet is easier to replace.
