Texas Electric Utilities
Deregulated delivery zones

Know your utility company

In the deregulated energy system, energy providers sell electricity to consumers, but electric utilities deliver the electricity and maintain power lines. If you experience a power outage, you’ll need to contact your utility company.

Your utility company can also change which plans or rates you are eligible for, so it is important to know which utility area you live in. Consumers cannot choose their utility company and all delivery fees are regulated by the Public Utility Commission of Texas (PUCT). Everyone in your area pays the same utility fees regardless of which energy provider they choose.

Most areas in Texas are served by one utility company, but some cities fall into two different service areas. If this is the case for your city, we will ask you to select your utility company when you enter your ZIP code above.

  • If you are switching providers, your utility company is listed on your last bill.
  • If you are moving, the city website may list its utility.
  • If you do not know, we will use your street address to select the correct one.
