There's no single answer in Texas — and that's by design. Most of the state is deregulated for electricity: a delivery utility like Oncor owns the wires while you choose your own retail plan. A handful of big cities (Austin, San Antonio) run municipal utilities instead. Gas, water and sewer are local in every city. Your address decides all of it.

In most of Texas, two different companies stand between you and your lights. A transmission and distribution utility (TDU) — Oncor in the Dallas–Fort Worth area, CenterPoint Energy around Houston, and others — owns the poles, wires and meters. TDUs deliver power and fix outages, and you never get to pick yours: it's determined entirely by your address. Separately, you choose a retail electricity provider, which is the company that sells you a plan and sends the bill.
The exceptions matter: Austin (Austin Energy), San Antonio (CPS Energy) and co-op territories opted out of deregulation, so residents there sign up directly with one utility and never shop for plans. Moving between these two worlds is exactly when people get confused — which is why checking your specific address beats any general rule.
City-by-city breakdowns of who provides electricity, gas, water and sewer:
It depends on where you live — Texas has no statewide electric company. In most metro areas a transmission and distribution utility (TDU) such as Oncor or CenterPoint Energy owns the wires, and you separately choose a retail electricity plan. Cities like Austin and San Antonio instead have municipal utilities that handle everything. Enter your address in the lookup to see exactly who serves your home.
Most Texans can. About 85% of the state is in the deregulated market, where you pick a retail electricity plan and the local TDU delivers the power. The big exceptions are municipal-utility cities (Austin Energy, CPS Energy in San Antonio) and electric co-op territory, where the utility that serves your address is your only option.
Water is almost always local: each city runs its own water utility, and many suburbs are served by municipal utility districts (MUDs) or special water districts instead. That's why the water row changes more often than any other when you look up different addresses in the same metro.
Use the address lookup on this page. It checks your exact address against utility territory data and returns your electric, gas, water and sewer providers with phone numbers and sign-up links — more reliable than any city-level list, including this one.
