Texas Electric Utility Companies

In the event of a power outage, the regulated Transmission and Distribution Utility company (TDU, or TDSP) in your area corrects outages, not the retail energy provider (REP) who sells you electricity.

Read our article to learn the difference between a TDU and a retail electric provider, as well as the different functions they perform.

TDUs maintain the wires and poles, check meters, and track your home’s energy usage. Their charges are included in the monthly bill you pay to your REP. You can conveniently access your kWh usage data at Smart Meter Texas.

The largest TDUs in Texas are Centerpoint Energy in the Houston metro area and Oncor Electric in the Dallas metro area. You’ll find background information on Texas TDUs, along with outage tracking links and contact information on our Centerpoint and Oncor profile pages, and our AEP American Electric Power, TNMP Texas New Mexico Power and Sharyland Utilities pages.

You can locate contact information for current Texas TDUs in our Texas power outage contact guide, where you’ll also find great tips on what to do in the event of a loss of power.
