Local knowledge for Santa Teresa, Dona Ana County

Santa Teresa has long, hot summers and mild winters, so cooling equipment does most of the electrical work. Panels in direct sun run hot, exposed conduit and cable degrade, and afternoon thunderstorms in monsoon season deliver frequent surges.

Most properties in Dona Ana County get their electricity from El Paso Electric. If your project touches the meter or main service, we handle the scheduling with the utility.

Our sub panel installation covers all of Santa Teresa, along with neighboring Sunland Park, Anthony, Chaparral, and Chamberino.

Sub Panel Installation FAQs for Santa Teresa

Sub panel or full panel upgrade: which do I need in Santa Teresa?

If the main service has enough capacity and you only need more spaces or power in a new location, a sub panel is usually enough. If the service itself is too small, you need a panel upgrade. We run the numbers and tell you which.

How big should a sub panel be?

A garage or small shop commonly uses 60 to 100 amps. A casita with its own cooking and cooling may need more. We size it to what you plan to run.

Can you run power to a detached building?

Yes. We trench, lay conduit, pull the feeder, and install the panel and grounding at the building.

Which areas around Santa Teresa do you cover for sub panel installation?

All of Santa Teresa and the surrounding Dona Ana County communities, including Sunland Park, Anthony, and Chaparral.
