If you have ever opened your Texas electricity bill and wondered why there are multiple company names listed, you are not alone. Many Texans sign up for a fixed-rate plan with a Retail Electric Provider (REP) like APG&E, only to see utility trucks from Oncor or CenterPoint servicing the power lines in their neighborhood. This division of labor is a fundamental feature of the deregulated Texas energy market, but it often leaves consumers asking: what is a transmission and distribution service provider (TDSP) and how does it differ from my retail provider?
The Clear Distinction: Retail Electric Provider vs. TDSP
In the Lone Star State, the entity that sells you electricity is entirely different from the entity that delivers it to your home. To navigate this system successfully, you must understand the distinct roles these two players assume in powering your daily life.
Your Retail Electric Provider (REP)
Your REP is the company you shop with, sign contracts with, and pay each month. REPs buy electricity from power generators and package it into various retail plans for consumers. For example, APG&E is a premier Texas REP known for offering structured bill predictability. When you choose their popular SimpleSaver 12 plan, APG&E establishes your fixed energy plan terms and supply structure for 12 months. They handle your billing, customer service, and help you secure stable energy rates.
Your Transmission and Distribution Service Provider (TDSP)
While APG&E manages your retail contract, your local TDSP (also commonly referred to as a Transmission and Distribution Utility, or TDU) remains the entity responsible for physically routing that electricity to your home meter. Regardless of which REP you select, your TDSP is determined strictly by your physical geography. They own and maintain the physical poles, wires, substations, and smart meters that keep the lights on. They are also the ones who respond to emergency power outages and downed lines.
The Six Major Texas Utilities and Their Territories
Texas is divided into distinct geographic utility service territories. Every home and business falls under the jurisdiction of one of the six major TDSPs operating within the ERCOT grid. Whether you are shopping for residential plans or looking to compare business electricity plans, your location dictates your utility:
- Oncor: The largest TDSP in Texas, serving millions of customers in northern and western parts of the state. If you are looking for reliable electricity dallas residents depend on, Oncor is your utility.
- CenterPoint Energy: Managing the electric infrastructure for the Houston metropolitan area. When shopping for the electricity Houston homes require, CenterPoint is the utility handling delivery.
- AEP Texas Central & AEP Texas North: Covering vast portions of southern and western Texas, these two divisions keep the grid stable for communities from Corpus Christi to Abilene.
- Texas New-Mexico Power (TNMP): Serving various pockets of Texas, including areas northeast of Houston, portions of West Texas, and communities south of Dallas-Fort Worth.
- Lubbock Power & Light (LP&L): The newest addition to the deregulated market, transitioning its customers into the competitive ERCOT grid to give West Texans the ability to choose their retail providers.

Understanding Pass-Through Charges
Even though you contract with APG&E for your energy supply, your monthly bill will include TDSP delivery charges. These are “pass-through” fees, meaning your REP collects them from you and passes them directly to your local utility. These delivery charges are strictly regulated by the Public Utility Commission of Texas (PUCT) and are updated twice a year. Because they are charged by the utility to maintain the grid, you will pay these same delivery fees regardless of which REP you choose or which plan structure you select.
Conclusion: Empowering Your Energy Decisions
Understanding the clear line of communication between your retail provider and your utility company is key to managing your home utility services. When you secure a fixed-rate plan through APG&E, you gain price stability for your energy supply, while your local TDSP works behind the scenes to maintain grid reliability. If your power goes out, you will contact your utility, but for billing and plan inquiries, your REP is your go-to partner.

Frequently Asked Questions
Do I get two separate bills from my REP and my TDSP?
No. You will only receive one consolidated monthly bill from your chosen Retail Electric Provider (REP), such as APG&E. This bill will clearly itemize your energy supply charges alongside the regulated TDSP delivery fees, which are passed through directly to your local utility company.
Who do I call if my power goes out or a power line is down?
You should always contact your local TDSP (such as Oncor, CenterPoint, or AEP) during an outage or emergency. Because the TDSP owns and maintains the physical infrastructure, your retail provider cannot dispatch crews to repair downed lines or restore power.
Can I choose a different TDSP to lower my delivery charges?
No. TDSP territories are geographically defined monopolies. You cannot change your utility provider because it is determined solely by the physical location of your home or business. However, you can choose your REP to secure the best possible energy supply terms.
