When you flip a switch in the Lone Star State, the electricity that floods your room travels a complex path. While many Texans know they can choose their retail electric provider (REP), few understand that their physical location dictates which utility company actually delivers that power. In Texas, your location determines your Transmission and Distribution Service Provider (TDSP)u2014the entity responsible for maintaining the physical grid, poles, and wires in your specific region.
The Role of the TDSP: Oncor, CenterPoint, AEP, and TNMP
Unlike retail providers who sell you energy plans, TDSPs (often called utilities) are responsible for the physical delivery of electricity. In Texas, there are four major investor-owned TDSPs: Oncor (serving Dallas-Fort Worth and surrounding areas), CenterPoint Energy (powering the Houston metroplex), AEP Texas (covering South and West Texas), and TNMP (serving various pockets across the state). No matter which retail provider you choose to compare Texas electricity rates and purchase power from, your local TDSP remains the same. They are the ones you call when trees knock down a power line or during a major storm outage.
How Utility Delivery Fees Impact Your Bill
Your monthly electricity bill is actually split into two main parts: the energy charge from your retail provider and the delivery charges from your TDSP. These TDSP fees are approved by the Public Utility Commission of Texas and are passed directly to the consumer without markup. This is why average prices per kWh are based on standard 1,000 kWh or 2,000 kWh monthly usage blocks, which include these fixed and variable local charges from regional utilities. Because each TDSP has different operational costs and regional terrains to manage, delivery fees vary by zone, meaning a plan in Houston might have a different final price than the exact same plan in Dallas.

Frequently Asked Questions
Can I choose my TDSP in Texas?
No. Your TDSP (such as Oncor or CenterPoint) is determined solely by your physical address and geographic location. You can only choose your Retail Electric Provider (REP).
Why does my neighbor have different plan options than me?
Electricity availability depends on whether your specific city is deregulated. Additionally, different utility zones have different delivery fees, which affects the overall pricing structure of available plans.
What is an EFL and why is it important?
The Electricity Facts Label (EFL) is a standardized document detailing a plan’s pricing at 500, 1,000, and 2,000 kWh usage levels, along with contract terms, fee structures, and the percentage of renewable energy used.
