Many Texans believe that when they choose an electricity provider, that specific company is the one running physical wires to their home and keeping the lights on. In reality, your electricity options and rates are entirely dictated by where you live in the Lone Star State. While you have the power to choose who bills you, a single regional utility company physically delivers your electricity. These utilities are known as Transmission and Distribution Service Providers (TDSPs).
What is a TDSP and Why Does It Matter?
Your TDSP (also commonly called a TDU) is the utility company responsible for maintaining the physical electricity grid, poles, wires, and meters in your region. In Texas, the major TDSPs include Oncor, CenterPoint Energy, AEP Texas, and Texas-New Mexico Power (TNMP). No matter which retail electric provider (REP) you sign up with, your local TDSP remains the same. It is also important to note that not all cities in Texas have electric choice; some municipal areas and cooperatives remain regulated, meaning you cannot shop for an independent provider there.
How TDSPs Impact Your Monthly Electricity Bill
Understanding TDU Charges on Your EFL
Pricing is based on each specific area’s utility rates, which are approved by the state. When you compare Texas electricity rates, you will notice that average prices per kWh are based on standard 1,000 kWh or 2,000 kWh monthly usage blocks. These blocks include both the retail energy charge and the fixed and variable local delivery charges from your regional TDSP. Because these delivery fees vary by utility zone, the same retail plan can have a different average price depending on where you live.
Rate Disclaimer and Structure
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 only finalized when an agreement is completed. Understanding these EFL documents is crucial to avoiding unexpected spikes on your monthly utility bill.

What is the difference between a REP and a TDSP?
A Retail Electric Provider (REP) sells you electricity plans and manages your billing. A Transmission and Distribution Service Provider (TDSP) physically delivers the electricity to your home, maintains the power lines, and responds to power outages.
Can I choose my TDSP in Texas?
No. Your TDSP is determined strictly by your physical geographic location. You cannot change your utility delivery company, but you can choose your retail provider if you live in a deregulated service area.
Why do electricity rates differ between Oncor and CenterPoint areas?
Each TDSP charges different state-approved rates for maintaining their regional grid infrastructure. These regional delivery fees are added to your retail rate, causing the final price per kWh to vary by utility zone.
