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, which appear on your electric bill regardless of which retail provider you choose.

Some ZIP codes cross more than one utility territory, so a ZIP code may occasionally need to be paired with additional location information before the correct TDU can be identified.

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.

TDU service territories do not follow city or ZIP-code boundaries perfectly.

A large metro area can include more than one delivery utility, and some ZIP codes can cross utility boundaries. Two homes only a few miles apart can therefore have access to different electricity plans.

There is another important distinction: 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.

Using your actual ZIP code is the quickest way to determine whether fixed-rate plans are available where you live.

We use your ZIP code to identify the applicable electricity market and show the fixed-rate plans available there.

Plans are compared using estimated cost rather than simply sorting by the advertised cents-per-kWh number. That matters because the advertised rate at one usage level does not always tell you which plan will cost less over a full contract term.

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.

Fixed Rate Electric Plans focuses on straightforward fixed-rate offers. Variable-rate, prepaid, time-of-use and bill-credit plans are not shown. Plans with minimum-usage charges may appear and are clearly identified.
