Imagine signing up for a highly competitive energy plan with a premier provider like Frontier Utilities, only to look out your window during a stormy night and see an Oncor truck repairing a nearby transformer. For many Texans navigating the deregulated energy market, this scenario raises a fundamental question: what is a transmission and distribution service provider, and how does it differ from the company that sends you your monthly bill?
Understanding the clear distinction between your Retail Electric Provider (REP) and your Transmission and Distribution Service Provider (TDSP)—often referred to as a utility—is the secret to demystifying your electricity statement and taking control of your household budget. In Texas, these two entities play completely different roles in keeping your lights on, and knowing who does what can save you time, money, and unnecessary confusion.
Provider vs. Utility: The Core Distinction
The easiest way to understand the Texas grid is to divide it into two functions: the company that sells you the energy, and the company that physically delivers it to your home.
Your Retail Electric Provider (REP) is the company you choose to handle your energy account. Prominent REPs like Frontier Utilities purchase electricity from wholesale generators, package it into retail plans, manage your billing, and provide customer service. When you shop for a new energy plan or look for options like a prepaid electric service, you are dealing directly with a retail provider.
On the other hand, your TDSP (Utility) is the company that owns and maintains the physical infrastructure. They own the poles, wires, high-voltage transmission lines, and smart meters that span across your region. Regardless of which retail provider you choose, your local utility is responsible for physically delivering that electricity to your home, reading your meter, and fixing downed power lines during an outage.
The Six Major Texas Utilities and Their Territories
While you have the freedom to shop around and use tools like the official power to choose portal to select your retail provider, you cannot choose your TDSP. Your utility is determined strictly by your physical geographic location. There are six major TDSPs servicing the deregulated ERCOT grid:
- Oncor: The largest utility in Texas, servicing millions of customers looking for reliable electricity dallas and the surrounding North Texas regions.
- CenterPoint Energy: The primary utility delivering electricity Houston and the surrounding gulf coast area.
- AEP Texas Central: Serves southern parts of the state, including Corpus Christi, McAllen, and Laredo.
- AEP Texas North: Covers western and northern territories, including Abilene and San Angelo.
- Texas New-Mexico Power (TNMP): Services various pockets across the state, including portions of the Gulf Coast, West Texas, and North-Central Texas.
- Lubbock Power & Light (LP&L): The newest addition to the competitive Texas market, completing its historic transition to allow customers to choose their retail providers.
How Frontier Utilities Pairs with Your Local Utility
When you choose a plan with a reliable provider like Frontier Utilities, you are securing your energy supply rate. For example, the popular Frontier Saver Premier 24 plan is designed to offer long-term rate stability by securing your base supply charges for a full 24 months. This shields you from the volatility of the wholesale energy market.
However, even with a stable fixed-rate supply contract, your local TDSP is still the entity delivering that power across the local lines. The delivery charges levied by your utility are regulated by the Public Utility Commission of Texas (PUCT) and are passed through to your bill. These charges cover the cost of maintaining the grid and are the same regardless of which retail provider you select.

Frequently Asked Questions
Who do I call if my power goes out?
If your electricity goes out or you see a downed power line, you must contact your local TDSP (such as Oncor, CenterPoint, or TNMP), not your retail provider. Your utility is the entity responsible for repairing physical infrastructure and restoring power.
Why do I see TDSP charges on my bill if I have a fixed-rate plan?
TDSP charges are regulated pass-through fees approved by the PUCT. They cover the cost of delivering electricity over the physical grid to your home. While a fixed-rate plan from a provider like Frontier Utilities secures your energy supply charge, the TDSP delivery charges are always passed through to the consumer regardless of the plan type.
Can I choose a different utility company to deliver my power?
No. While you have the power to choose your Retail Electric Provider (REP), your Transmission and Distribution Service Provider (TDSP) is determined solely by your physical geographic location and cannot be changed.
