If you live in the Lone Star State, you quickly learn that where you lay your head at night completely dictates how you power your home. While Texas is famous for its deregulated energy market, many residents do not realize that their electricity experience is actually split between two different entities: the Retail Electric Provider (REP) you pay your bill to, and the Transmission and Distribution Service Provider (TDSP) that physically delivers the electricity to your door.
Understanding the TDSP: The Silent Giants of Texas Power
While you have the power to choose your retail provider, your TDSP (often called your local utility company) is determined solely by your geographic location. You cannot choose your TDSP. These companies own and maintain the physical poles, wires, and meters that keep your lights on. When storm winds blow and the power goes out, it is your TDSP—not your retail provider—that sends out the bucket trucks to restore your service.
Who is Your Regional Delivery Utility?
Texas is carved into distinct utility zones, each managed by a specific TDSP:
- Oncor: Serving the Dallas-Fort Worth metroplex and parts of West Texas.
- CenterPoint Energy: Powering the greater Houston area and surrounding coastal regions.
- AEP Texas (Central and North): Delivering power to South Texas, the Rio Grande Valley, and parts of West Texas.
- Texas-New Mexico Power (TNMP): Serving various pockets across the state, including areas gulf-ward of Houston and parts of West Texas.
Each utility charges its own set of delivery fees, which are approved by the Public Utility Commission of Texas (PUCT). These fees are passed directly to consumers and are included in your monthly bill. This is why average prices per kWh—typically calculated based on standard 1,000 kWh or 2,000 kWh monthly usage blocks—vary so much depending on where you live. These blocks include both fixed and variable local charges from your regional utility.
How Delivery Fees Impact Your Electric Bill
When you use our platform to compare Texas electricity rates, it is crucial to remember that pricing is heavily based on each specific area’s utility rates. Furthermore, not all cities in Texas have electric choice; some municipal utilities and cooperatives remain regulated. At BulbOne, we operate as an independent resource to help you make sense of these regional differences. Please note that we are in no way associated with PowerToChoose.org (which is operated by the PUC of Texas).
Our goal is to help you explore your power to choose the best, most cost-effective, and reliable cheap electricity plans in Texas. Electricity service offers can be fixed or variable. The rates displayed on our platform are gathered directly from each provider’s Electricity Facts Label (EFL) for comparison purposes only. Rates are subject to change and are only finalized when your agreement is completed.

Frequently Asked Questions
Can I choose a different TDSP to lower my delivery rates?
No. Your TDSP is determined entirely by your physical location and cannot be changed. All residents in a specific utility service area pay the same regulated delivery fees, regardless of which retail electric provider they choose.
How do TDSP charges affect my average price per kWh?
TDSP charges consist of a flat monthly fee and a per-kWh delivery fee. When retail providers advertise rates based on 1,000 kWh or 2,000 kWh usage, these regional utility fees are factored into that average price, causing the final rate to vary by region.
Does every city in Texas have the option to choose their electricity provider?
No. While about 85% of Texas is deregulated, several cities (like Austin and San Antonio) and rural areas served by electric cooperatives are regulated, meaning residents must use the designated local utility.
