In Texas, flipping a light switch feels instant, but the journey that electricity takes to reach your home is dictated entirely by where you live. While you have the power to choose your retail electric provider (REP), a completely different entity is responsible for physically delivering that power to your door.
What is a TDSP and Why Does It Matter?
TDSP stands for Transmission and Distribution Service Provider (often called your local utility). Unlike REPs, which handle your billing and customer service, TDSPs own and maintain the physical poles, wires, and meters. In Texas, the major TDSPs are Oncor, CenterPoint Energy, AEP Texas, and Texas-New Mexico Power (TNMP). You cannot choose your TDSP; it is determined strictly by your geographic location.
How TDSP Charges Affect Your Electric Bill
When you compare Texas electricity rates, you will notice that average prices per kWh are typically structured around standard 1,000 kWh or 2,000 kWh monthly usage blocks. These estimated rates include both the retail rate from your provider and the fixed and variable local charges set by your regional TDSP. Because these utility delivery fees vary by region, the exact same retail plan can cost more or less depending on your specific utility zone.

To keep you fully informed, remember that electricity service offers can be fixed or variable. All rates shown 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. Additionally, not all cities in Texas have electric choice, as some remain regulated or are served by cooperatives.

Frequently Asked Questions
Can I choose my TDSP in Texas?
No. Your TDSP is determined solely by your physical location and cannot be changed. They are responsible for maintaining the grid and restoring power during outages.
Why does my neighbor have different electricity options than me?
Electricity choice depends on whether your specific city is deregulated. Some municipal utilities and electric cooperatives are exempt from deregulation, meaning residents in those areas cannot shop for third-party providers.
How do TDSP fees impact my monthly bill?
TDSP charges are approved by the PUC of Texas and are passed through to the consumer. They include a flat monthly charge and a per-kWh usage fee, which are factored into the average price per kWh shown on your plan’s Electricity Facts Label.
