Find your TDU territory and compare plans available in your area.
In deregulated Texas, your electricity comes from two companies: a Transmission and Distribution Utility (TDU) that owns the wires and delivers power to your home, and a Retail Electric Provider (REP) that you choose to bill you. Your TDU is determined by your address — you can’t change it. But you can choose any REP that serves your TDU territory.

No. Your TDU is determined by your physical address and you can't switch — only your Retail Electric Provider (REP) is changeable. If you live in CenterPoint territory, CenterPoint delivers your power regardless of which REP you sign up with.
Texas separates the cost of delivering electricity (TDU charges) from the cost of generating it (your REP's energy charges). TDU charges are regulated and the same for everyone in a territory. Energy charges vary by REP and plan — that's where shopping for a better deal matters.
Call your TDU directly, not your REP. Each TDU has its own outage hotline: CenterPoint (713-207-2222), Oncor (888-313-4747), AEP Texas (866-223-8508), TNMP (888-866-7456). Your REP doesn't handle outages — they only handle billing.
Yes. TDU delivery charges vary by territory — CenterPoint has different rates than Oncor, for example. When comparing electricity plans, the rate you pay = REP energy charge + TDU delivery charge + applicable taxes. AskTexasEnergy shows the true all-in rate, not just the REP's headline price.
Enter your ZIP code in the search above and we'll tell you. You can also check the bottom of your electricity bill — your TDU's name is listed there. Or call your current REP and ask.
