When you flip a light switch in the Lone Star State, a complex, multi-layered energy system springs into action. While many Texans spend their time shopping for retail electric providers, your actual energy options, grid reliability, and utility delivery fees are entirely dictated by where you live in Texas. Understanding who actually delivers your power is the first step to making sense of your monthly energy bill.
What is a TDSP and Why Does It Matter?
In the deregulated Texas energy market, electricity is split into two main components: generation/retail sales and physical delivery. The company that sells you the electricity (your Retail Electric Provider, or REP) is not the company that owns the poles and wires. That job belongs to your Transmission and Distribution Service Provider (TDSP)—often simply referred to as your local utility company.
No matter which retail provider you choose to buy your power from, your TDSP remains the same based on your geographic location. These utilities are responsible for maintaining the physical power lines, reading your electric meter, and responding to power outages during storms. Because they operate as regulated monopolies in their respective territories, you cannot choose your TDSP.
The Big Four: Meet the Texas Utility Giants
Texas is divided into distinct utility service areas, each managed by a specific TDSP. Depending on where your home or business is located, you will fall under one of these major entities:
Oncor Electric Delivery
As the largest TDSP in Texas, Oncor services millions of customers across northern, western, and central parts of the state. If you are looking for electricity Fort Worth residents rely on, or if you reside in Dallas, Waco, or Wichita Falls, Oncor is the utility maintaining your grid infrastructure.
CenterPoint Energy
CenterPoint covers the Houston metropolitan area and parts of southern Texas. When searching for the best deals on electricity Houston homes require, your delivery charges will be determined by CenterPoint’s regulated rates, regardless of which retail plan you select.
AEP Texas
AEP Texas is divided into two primary regions: AEP Central (covering places like Corpus Christi, McAllen, and Laredo) and AEP North (serving Abilene, San Angelo, and surrounding areas). They manage the vast network of transmission lines keeping South and West Texas connected.
Texas-New Mexico Power (TNMP)
TNMP services various pockets of Texas, including communities adjacent to the Gulf Coast, parts of North Texas, and far West Texas. This includes cities like League City, Angleton, and Lewisville.
How TDSP Charges Affect Your Electricity Bill
When you use an independent platform to compare Texas electricity rates, you will notice that average prices per kWh are typically based on standard 1,000 kWh or 2,000 kWh monthly usage blocks. These estimated rates include both the energy charge from your REP and the fixed and variable local delivery charges set by your regional TDSP.
These delivery fees are approved by the Public Utility Commission of Texas (PUCT) and are passed directly through to the consumer without any markup from your retail provider. This is why a plan that looks incredibly cheap in one city might have a slightly different average rate in another; the underlying utility delivery fees vary by region.
Navigating Your Choices with BulbOne
At BulbOne, we act as your expert guide and independent platform to help you navigate these regional grid complexities. We empower consumers to explore their power to choose the best, most cost-effective, and reliable cheap electricity plans in Texas. Whether you are looking for traditional fixed-rate plans, flexible prepaid electric service, or searching for competitive rates from small business electricity providers, we simplify the comparison process.
Please note that pricing is based entirely on each specific area’s utility rates, and not all cities in Texas have electric choice (some municipal utilities and cooperatives remain regulated). Additionally, electricity service offers can be fixed or variable. All rates displayed on our platform are gathered directly from each provider’s Electricity Facts Label (EFL) for comparison purposes only. These rates are subject to change and are only finalized when your formal agreement with the provider is completed. BulbOne is an independent resource and is in no way associated with PowerToChoose.org (which is operated by the PUC of Texas).

Can I choose my TDSP in Texas?
No. While you can choose your Retail Electric Provider (REP) in deregulated areas of Texas, your Transmission and Distribution Service Provider (TDSP) is determined solely by your physical geographic location and cannot be changed.
Who do I call if my power goes out?
You should always call your local TDSP (such as Oncor, CenterPoint, AEP, or TNMP) to report power outages or downed lines. Your retail electric provider only handles billing and enrollment; the TDSP maintains the physical grid infrastructure.
Why does the same electricity plan have different rates in different cities?
Even if you select the exact same retail plan, the total average price per kWh may vary because different TDSPs charge different regulated rates for delivering power to your home. These regional utility delivery fees are factored into the standard 1,000 kWh and 2,000 kWh usage block calculations on your Electricity Facts Label (EFL).
