In the Lone Star State, your electricity options and monthly bills are heavily dictated by where you live. While you might spend time choosing a retail electric provider (REP) to bill you, a completely different entity is responsible for actually delivering that power to your home. These entities are Transmission and Distribution Service Providers (TDSPs), also known as your local utility companies.
What is a TDSP and Why Does It Matter?
Unlike your retail provider, you cannot choose your TDSP. These utilities—such as Oncor in Dallas-Fort Worth, CenterPoint in Houston, AEP Texas in South and West Texas, and Texas-New Mexico Power (TNMP)—own and maintain the physical poles, wires, and meters. No matter which retail plan you select, your local TDSP is the company that responds to power outages and ensures the physical delivery of electricity to your doorstep.
How TDSPs Impact Your Electricity Rates
Every monthly electric bill includes TDSP delivery charges, which cover the maintenance of the regional grid. Because of this, pricing is based on each specific area’s utility rates, and not all cities in Texas have electric choice. When you compare Texas electricity rates, it is important to understand that average prices per kWh are based on standard 1,000 kWh or 2,000 kWh monthly usage blocks. These estimates include both fixed and variable local charges from your regional TDSP, meaning the exact same retail plan can cost more or less depending on your utility zone.

Frequently Asked Questions
Can I choose my TDSP in Texas?
No. Your TDSP is determined strictly by your physical location. While you can choose your Retail Electric Provider (REP) in deregulated areas, your local utility company (like Oncor or CenterPoint) remains responsible for delivery.
Why do electricity rates differ between Houston and Dallas?
Each TDSP charges different approved rates for maintaining their local grid infrastructure. These regional delivery fees are added to your retail rate, causing the average price per kWh to vary by location.
What is an Electricity Facts Label (EFL)?
An EFL is a standardized document detailing a plan’s pricing structure at 500, 1,000, and 2,000 kWh usage blocks, including both retail costs and TDSP delivery fees.
