Ever looked at your Texas electricity bill and wondered why there are two different company names involved in powering your home? You’re not alone. In the deregulated Texas energy market, understanding the roles of your Retail Electric Provider (REP) and your Transmission and Distribution Service Provider (TDSP) is key to navigating your service, understanding your charges, and knowing exactly who to call when you need assistance.
The Two Sides of Your Texas Electricity Service
In simple terms, your electricity service in Texas is a partnership between two distinct entities: the company that sells you the electricity (your REP) and the company that physically delivers it to your home or business (your TDSP). While both are crucial, their responsibilities are entirely separate, a distinction that often causes confusion for consumers.
Unpacking the Role of Your REP
Your Retail Electric Provider (REP) is the company you choose to buy electricity from. They are responsible for setting your energy plan, managing your account, sending your monthly bill, and handling customer service related to your plan and usage. In the competitive Texas market, you have the power to shop for the best rates and terms from a variety of REPs.
ElectricityOne understands this choice can be overwhelming. With over 20 years of experience, we act as a prominent platform connecting Texans with the finest Retail Electric Providers in the state. Our meticulous provider selection process ensures we partner only with REPs that offer substantial cost savings, transparent disclosure of all costs and fees (including those pass-through TDSP charges), and a commitment to long-term satisfaction. For Texans seeking flexibility and budget control, we often highlight partners like Payless Power. They offer excellent prepaid options such as the Payless 12 Month – Prepaid plan and the Payless 6 Month – Prepaid plan, which are fantastic choices for managing your budget without requiring a credit check or deposit.
Understanding Your TDSP: The Unsung Heroes of the Grid
So, what is a transmission and distribution service provider? Your TDSP, also known as a Transmission and Distribution Utility (TDU), is the company that owns, operates, and maintains the physical infrastructure that delivers electricity to your property. This includes the power lines, utility poles, transformers, and smart meters. They are responsible for ensuring the reliability of the grid, performing maintenance, and responding to power outages and downed power lines.
Unlike REPs, you cannot choose your TDSP; it’s determined by your geographic location. The major TDSPs serving the deregulated areas of Texas include:
- Oncor Electric Delivery: Serving much of North and Central Texas, including Dallas and Fort Worth.
- CenterPoint Energy: Primarily serving the Houston metropolitan area and surrounding communities.
- AEP Texas North: Covering parts of West Texas, including Abilene and San Angelo.
- AEP Texas Central: Serving South Texas, including Corpus Christi and Victoria.
- Texas-New Mexico Power (TNMP): Operating in various scattered communities across the state, including some suburban and rural areas.
- Lubbock Power & Light (LP&L): Recently transitioned into the competitive market, bringing customer choice to Lubbock residents while maintaining the local grid infrastructure.
These six utilities are the backbone of the ERCOT grid, diligently maintaining the infrastructure that ensures power flows to your home, regardless of which REP you choose. Their regulated delivery charges appear on every monthly statement, passed through by your REP.

Frequently Asked Questions About TDSPs
What’s the main difference between my REP and my TDSP?
Your REP (Retail Electric Provider) sells you electricity and manages your billing and plan. Your TDSP (Transmission and Distribution Service Provider) owns and maintains the physical power lines and equipment that deliver electricity to your property.
Who do I call if my power goes out?
Always call your local TDSP directly for power outages, downed power lines, or any other infrastructure-related emergencies. Your REP cannot fix physical grid issues.
Do TDSP charges change if I switch electricity providers?
No, TDSP delivery charges are regulated and apply to all customers within a specific TDSP service territory, regardless of which Retail Electric Provider you choose. These charges will appear on your bill from your REP as pass-through fees.
