When you flip a switch in the Lone Star State, a complex network springs to life to deliver electricity to your home. While you might buy your power from a Retail Electric Provider (REP), the physical delivery of that power relies entirely on where you live. Your location determines your Transmission and Distribution Service Provider (TDSP)—the utility company responsible for maintaining the poles, wires, and meters in your specific region.
Understanding Your TDSP: The Silent Giants of Texas Power
Unlike REPs, which compete for your business in deregulated areas, TDSPs are regulated monopolies bound to specific geographic territories. In Texas, there are four major TDSPs: Oncor (serving Dallas-Fort Worth and West Texas), CenterPoint Energy (powering the Houston metro area), AEP Texas (covering South and West Texas), and Texas-New Mexico Power (TNMP, serving various pockets across the state). Whether you want to compare Texas electricity rates or report a physical power outage, understanding which TDSP manages your local grid is essential.
How TDSP Charges Impact Your Monthly Bill
Your monthly electric bill is actually split into two main parts: the energy supply charge from your REP and the delivery charges from your TDSP. It is important to note that average prices per kWh are typically calculated based on standard monthly usage blocks of 1,000 kWh or 2,000 kWh. These calculations include both fixed and variable local charges passed down by your regional utility. Because these delivery fees vary by TDSP, the same retail plan can cost different amounts depending on your zip code.
At BulbOne, we act as an expert guide and independent platform to help you navigate these regional differences and find the best, most cost-effective, and reliable cheap electricity plans in Texas. Please remember that not all cities in Texas have electric choice, as some remain fully regulated. Electricity service offers can be fixed or variable, and all rates displayed on our platform 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. Additionally, BulbOne is an independent resource and is in no way associated with PowerToChoose.org, which is operated by the Public Utility Commission (PUC) of Texas.
Navigating utility zones does not have to be complicated. Let BulbOne simplify the process and help you find the ideal plan for your local utility footprint.

What is the difference between an REP and a TDSP?
An REP (Retail Electric Provider) sells you electricity plans and handles billing, while a TDSP (Transmission and Distribution Service Provider) physically delivers the power, maintains the grid infrastructure, and responds to outages in your specific region.
Can I choose my TDSP in Texas?
No. TDSPs are determined strictly by your geographic location and are regulated utility monopolies. You can choose your retail provider in deregulated areas, but your delivery utility remains the same.
Why do electricity rates differ between Texas cities?
Even if you choose the exact same retail plan, the total cost per kWh differs because regional TDSPs charge different regulated delivery fees, which are factored into your standard 1,000 kWh or 2,000 kWh usage blocks.
