List of Texas Utility Companies
AEP Texas is a subsidiary of American Electric Power (AEP) and delivers electricity to over one million customers. AEP Texas is unique because the electricity plans available to you depend on where you live in AEP Texas’s service area.
The other area is designated as AEP Texas Central, and while some of its service area runs throughout the central parts of the state, the majority is in the south.
CenterPoint Energy delivers electricity to 2.5 million+ customers in the greater Houston area.
Oncor is the largest electric utility provider in Texas, serving over 10 million customers throughout the state. A bulk of their service area is in Dallas, Fort Worth and the surrounding areas. However, it also serves portions of western Texas.
Texas-New Mexico Power (TNMP) is the smallest utility provider out of the four, serving 255,000 homes and businesses throughout the state. Its service area is sporadic, with larger areas in west Texas and south of Houston, and some service areas in the Dallas-Fort Worth metroplex.

The other utility companies in Texas don’t offer electricity choice. There are two types:

What Is A Utility Company?
An electric utility company delivers electricity to your home. They own and maintain the electrical infrastructure (poles, wires, transformers, etc.) to ensure you have reliable electricity service. Utility companies in Texas are regulated by the Texas Public Utilities Commission who is responsible for oversight of the deregulated electricity market and ensuring fair practices.
There is only one utility provider for a designated area. For example, Houston’s only electric utility company is CenterPoint Energy. This means you can’t change utility providers. Where you live determines your utility company.
How is a Utility Different than an Electricity Provider?
While your local utility in Texas maintains the infrastructure and safe delivery of energy to your home, the electricity provider is who supplies that electricity. They also determine the rate and terms that you pay for that supply. Electricity providers partner with utilities to ensure you always have safe & reliable service at the terms you agree to when you sign up for electricity.
Here are a few other key differences between a utility and an electricity provider:
- Maintains infrastructure for transmission of electricity (poles, wires, etc.)
- Ensures safe & reliable delivery of electricity to your home
- Takes care of all emergencies including outages and downed power lines
- Provides the supply of electricity that your utility then delivers to you
- Determines the electricity supply rate, contract length, and other terms of your service
- Sends your monthly electricity bill
