Opening a Texas electric bill can sometimes lead to confusion, especially when you see multiple company names listed on your statement. Perhaps you spent time researching the best retail option, ultimately selecting a sustainable plan from Gexa Energy, yet you notice the name Oncor, CenterPoint, or another utility company prominently displayed. To understand how your power is managed and delivered, it is essential to first understand: what is a transmission and distribution service provider?
Retail Providers vs. Utility Companies: The Clear Distinction
The Texas deregulated energy market splits the responsibilities of selling electricity and maintaining the physical power grid between two distinct entities: Retail Electric Providers (REPs) and Transmission and Distribution Service Providers (TDSPs, also commonly referred to as TDUs). Knowing the difference ensures you know who to contact for billing questions and who to call during an outage.
Your REP is the company you choose to buy your electricity from. Prominent providers like Gexa Energy specialize in offering tailored plans for your home. For instance, when you enroll in the popular Gexa Eco Saver Plus 12 Plan, Gexa works to offset your household’s electricity usage with 100% renewable energy credits for a full year. However, Gexa does not own the physical infrastructure. It is your local TDSP that acts as the physical entity moving those green electrons over the wires, managing your smart meter, and maintaining the poles in your neighborhood.
The Six Major Texas Utilities and Their Territories
Regardless of which REP you select, your geographical location dictates your TDSP. The physical delivery of your power is handled by one of six major utilities across the state:
- Oncor: The largest TDSP in Texas, serving millions of customers, including those looking for reliable electricity dallas residents depend on daily.
- CenterPoint Energy: Managing the grid across the Gulf Coast region, maintaining the transmission lines that deliver electricity Houston homes and businesses require.
- AEP Texas Central & AEP Texas North: Covering vast portions of South and West Texas, keeping remote and urban communities connected.
- Texas New-Mexico Power (TNMP): Servicing distinct pockets across the state, from northeast communities to the Gulf Coast.
- Lubbock Power & Light (LP&L): The newest addition to the deregulated ERCOT landscape, giving West Texans the freedom and power to choose their retail provider.
Whether you need standard residential power, temporary prepaid electric service, or commercial-grade business electricity plans, your local TDSP remains the constant physical backbone of your service. They charge standardized, regulated delivery fees that are passed through directly to your retail energy bill.

Frequently Asked Questions
What is the difference between my electric provider (REP) and my TDSP?
Your Retail Electric Provider (REP) is the company you purchase energy from, manages your account, and bills you monthly. Your Transmission and Distribution Service Provider (TDSP) is the regulated utility company that owns and maintains the physical poles, wires, and meters that deliver electricity to your property.
Will choosing a green energy plan from Gexa Energy change who delivers my power?
No. When you choose an eco-friendly plan like the Gexa Eco Saver Plus 12 Plan, Gexa Energy offsets your usage with renewable energy credits. However, your local TDSP (such as Oncor or CenterPoint) will continue to physically transport the electricity to your home over the same grid infrastructure.
Who do I contact during a power outage?
In the event of a power outage or downed power line, you should always contact your local TDSP directly, rather than your retail provider. Your TDSP is responsible for physical grid repairs and has crews stationed regionally to restore electricity safely and quickly.
