Texas Electricity Rates by ZIP Code

Electricity plans in Texas are not offered statewide at one uniform price.

Your ZIP code helps determine which Transmission and Distribution Utility, or TDU, serves your area. The TDU owns and maintains the poles, wires and meters that deliver electricity to your home.

That matters for two reasons. Retail electricity providers may offer different plans in different TDU territories. And each TDU has its own regulated delivery charges, set by the state regulator rather than by the retailer you choose.

Your ZIP code does not set the retail electricity rate a provider offers you.

Retail electricity providers set their own plan prices and contract terms. Your monthly electricity usage then has a major effect on what you ultimately pay.

That is why two households in the same ZIP code can have very different bills even when they are on the same plan.

A ZIP code is a Postal Service tool for sorting mail. It is not drawn to match electricity delivery areas.

Each TDU's delivery area is described by the cities and counties it covers. A large metro area can include more than one TDU, so two homes a few miles apart can be offered different electricity plans.

Not every part of Texas has retail electricity choice.

Austin and San Antonio, for example, are served by city-owned utilities, and El Paso is served by a regulated utility outside the competitive market. Many other areas are served by municipal utilities or electric cooperatives. Customers in those areas generally do not choose among competing retail electricity providers.

Your TDU is not the retailer you pay, and a recent bill is the first place to look for its name. Texas rules let a retailer print that name beside the delivery charges, but they also let a retailer show those charges as one combined total. The name may not appear on your bill.

The utility serving a home is set by the address, so a ZIP code narrows the possibilities without always answering the question.

When a ZIP code covers more than one TDU, this site asks which one serves you rather than choosing for you. Delivery charges differ between them, so the wrong one would show you prices meant for the other area.

The page shows fixed-rate plans sold in your delivery area.

Texas retail electricity providers publish an Electricity Facts Label for every plan they offer, a standard summary of the plan's terms. For a residential plan, Texas rules require that label to show an average price at 500, 1,000 and 2,000 kilowatt-hours a month. The same plan can work out to a different price per kilowatt-hour at each of those levels.

Plans are ranked by what twelve months would cost at the usage level you pick, not by the advertised rate alone. That twelve-month cost is calculated from the price the provider published at that level.

Your ZIP code is submitted securely and is not added to the page URL. No account, email address or street address is required to compare plans.

This site lists fixed-rate plans. Variable-rate, prepaid, time-of-use and bill-credit plans are not shown. Plans with minimum-usage charges may appear and are clearly identified.
