In the vast landscape of the Lone Star State, your electricity options and rates are entirely dictated by where you live. While Texas is famous for its deregulated energy market, offering consumers the power to choose their electricity provider, it’s crucial to understand the foundational players who ensure that power actually reaches your home: the Transmission and Distribution Service Providers, or TDSPs.
The Backbone of Your Texas Electricity Service: TDSPs
Think of TDSPs as the silent heroes of the Texas power grid. These are the utility companies responsible for building, maintaining, and operating the poles, wires, and infrastructure that deliver electricity from power plants to your meter. They’re also the first responders when an outage occurs. In Texas, the major TDSPs include Oncor, CenterPoint Energy, AEP Texas (North and Central), and Texas-New Mexico Power (TNMP).
Unlike your Retail Electric Provider (REP), which you can choose in deregulated areas, you cannot choose your TDSP. Your TDSP is assigned to you based on your specific geographic location. This means if you live in Dallas, your TDSP is Oncor; in Houston, it’s CenterPoint. These companies are regulated by the Public Utility Commission of Texas (PUC) and operate as monopolies within their designated service territories.
Why TDSP Charges Impact Your Bill
Every electricity bill in Texas, regardless of your chosen REP or whether your city has electric choice, includes charges from your local TDSP. These charges cover the cost of maintaining the grid, transmitting power, and reading meters. They are a significant component of your overall electricity cost and contribute to why Texas electricity rates vary by region.
At BulbOne, we understand that pricing is based on each specific area’s utility rates. When you see average prices per kWh, remember these are typically based on standard 1,000 kWh or 2,000 kWh monthly usage blocks, which include both fixed and variable local charges from these regional utilities. It’s also important to note that not all cities in Texas have electric choice; some areas remain regulated, meaning you don’t get to pick your REP.
BulbOne is an expert guide and independent platform, helping consumers explore their power to choose the best, most cost-effective, and reliable cheap electricity plans in Texas. We help you navigate these complexities to compare Texas electricity rates effectively. Electricity service offers can be fixed or variable, and rates 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 an agreement is completed.
BulbOne is an independent resource and is in no way associated with PowerToChoose.org, which is operated by the PUC of Texas. We’re here to empower Texans with clear, actionable information.

Frequently Asked Questions About Texas TDSPs
What is a TDSP in Texas?
A TDSP, or Transmission and Distribution Service Provider, is the utility company responsible for delivering electricity to your home, maintaining the power lines and poles, and responding to outages in a specific geographic area of Texas.
Can I choose my TDSP?
No, you cannot choose your TDSP. Your TDSP is determined by your geographic location and is the designated utility for that service territory. Your choice comes in selecting a Retail Electric Provider (REP) in deregulated areas.
How do TDSPs affect my electricity bill?
TDSPs charge fees for their services (like maintaining the grid and delivering power), which are included in your overall electricity bill. These charges are a significant part of your total cost per kWh and are the same regardless of your chosen electricity provider.
