Texas is famous for its vast landscapes, but when it comes to the electric grid, your geographic location dictates everything about how your power is delivered and priced. While you have the power to choose your retail electric provider (REP) in deregulated areas, the physical delivery of your electricity is managed by a completely different entity: your Transmission and Distribution Service Provider (TDSP). Understanding this distinction is key to finding the most cost-effective energy plan for your home.
What is a TDSP and Why Does It Matter?
Often referred to simply as the utility company, your TDSP is responsible for maintaining the physical power lines, poles, and meters in your specific region. Whether you live in Dallas, Houston, Corpus Christi, or a smaller Texas town, you do not get to choose your TDSP. Companies like Oncor, CenterPoint Energy, AEP Texas, and Texas-New Mexico Power (TNMP) operate as regulated monopolies within their designated service territories. They are the ones you call when the trees knock down a power line or during a local blackout.
How TDSPs Impact Your Electricity Bill
Understanding Delivery Charges and Usage Blocks
Even when you compare Texas electricity rates to find a cheap energy plan, a portion of your monthly bill always goes directly to your local TDSP. These delivery charges are approved by the Public Utility Commission of Texas (PUCT) and are passed through to the consumer without any markup from your retail provider. When shopping, you will notice that average prices per kWh are calculated based on standard monthly usage blocks of 1,000 kWh or 2,000 kWh. These estimates include both the retail energy rate and these fixed and variable local utility charges.
Comparing Plans with the EFL
Because TDSP charges vary by region, a plan that looks incredibly cheap in Houston (CenterPoint territory) might have a different average cost in Dallas (Oncor territory). As you explore your options, remember that electricity service offers can be fixed or variable. All comparison rates 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 is completed.

Frequently Asked Questions
Can I choose my TDSP in Texas?
No. While you can choose your Retail Electric Provider (REP) in deregulated areas of Texas, your TDSP (such as Oncor, CenterPoint, AEP, or TNMP) is determined solely by your physical location and cannot be changed.
Why do electricity rates differ between Texas utility zones?
Rates differ because each regional TDSP charges different approved rates for maintaining their local grid infrastructure. These transmission and distribution fees are factored into your overall price per kWh, causing variations across different parts of the state.
Are TDSP charges fixed or variable?
TDSP charges contain both a fixed monthly base fee and a variable charge per kWh. These fees are updated twice a year and apply equally to all consumers within that utility’s service territory, regardless of their chosen retail provider.
