Find Your TDU: Transmission and Distribution Utilities in Texas
When you purchase electricity in Texas, there are actually two companies involved in the sale. The Retail Electricity Provider (REP) sells energy plans to homes and businesses, while the Transmission and Distribution Utility (TDU) delivers that energy to the point of use with power lines and transformers.
You can choose your electricity provider, but your TDU is determined by your address, since only one company is in charge of the power grid for a given area.
- TDUs are also called TDSPs (Transmission and Distribution Service Providers).
- Your local TDU is who you call when there are power outages and other emergencies related to the ERCOT grid.
There are six electric utility providers in Texas:
Most of the Dallas/Fort Worth metropolitan area is served by Oncor, and Houston is home to CenterPoint. AEP North delivers power to Abilene and surrounding areas, while AEP Central covers Corpus Christi and the Rio Grande Valley. TNMP service locations include Lewisville and many Gulf Coast communities. LP&L is the TDU for the Lubbock area.

AEP Texas Central & AEP Texas North
American Electric Power (AEP) is present in 11 states, serving more than 5 million customers. The company is divided into two business units in the Lone Star State: AEP Texas Central and AEP Texas North. These two TDUs were formed by merging several smaller companies, which were acquired by AEP in 1997.
AEP Texas Electric Service Area
American Electric Power has the AEP Texas Central and AEP Texas North divisions, as mentioned above. However, the service territories of the two TDUs are actually different from what their names might suggest:
- AEP Texas North covers many areas in the center and west of the state, and only some northern areas south of Amarillo.
- AEP Texas Central covers many southern areas near the US-Mexico border.
The list of cities served by AEP Texas Central and AEP Texas North includes Corpus Christi, Abilene, McAllen, Harlingen, San Angelo, Vernon, Victoria and Laredo.
Energy Community Action
AEP’s Avian Protection Plan manages bird and power line interactions through a system-wide program across 11-states they service. The Avian plan works to protect larger species of birds from being electrocuted by substations, towers, and power lines.
AEP also provides incentive programs for many of their customers within the Texas Central zone. The programs in place help low-income households (below 200% federal poverty guidelines), new homeowners, solar homeowners, and customers who simply keep up service on their air conditioning units.
The specific incentives available vary for AEP Texas North and AEP Texas Central. However, both divisions have the Targeted Low Income Program, which is available for households at or below 200% of the federal poverty line. The program focuses on weatherization and energy efficiency measures, offering up to $6,500 per home.

Lubbock Power and Light (LP&L)
Lubbock Power and Light (LP&L) was the first municipal utility to join the competitive energy market voluntarily. Starting from January 2024, Lubbock residents can choose their retail electricity provider (REP) and LP&L operates as the utility company in charge of the local grid.
Here is a quick timeline of the LP&L deregulation process:
- In March 2018, the Public Utility Commission of Texas (PUCT) approved LP&L’s application to join ERCOT.
- The company transferred 70% of its customers and power system to the ERCOT grid on May 29-30, 2021.
- LP&L completed the process on December 9-11, 2023, transferring the remaining 30% of their customer base.
The LP&L deregulation process represents the largest electrical load migration ever completed in Texas.
Starting from January 5, 2024, Lubbock residents can compare electricity providers and choose an energy plan.
In March 2024, LP&L will issue their final power bill and all customers will be transferred to the competitive power market, under their chosen electricity plan. Note that customers don’t have the option of staying with LP&L, since the company will no longer sell electricity directly.
LP&L has been serving the city of Lubbock since 1916. Before joining the deregulated electricity market, LP&L was the 3rd largest municipal utility after CPS Energy (San Antonio) and Austin Energy. LP&L has more than 108,000 customers and over 300 employees. The company owns 38 substations and more than 4,936 miles of power lines.
LP&L Service Area
LP&L was originally created as a municipal power company serving the City of Lubbock.
Energy Community Action
Through the Powerful Pointers program, LP&L partners with ENERGY STAR to help their customers save energy at home.

The Difference Between Utility Providers and Electric Companies in Texas
While your TDU distributes electricity and provides maintenance for the power grid in your area, the electricity company you choose will set up your account and send your bill. Texans who live in energy deregulated areas (90% of the state) have a choice in electric providers.
