How to start electricity service in Round Rock
- 1
Choose a plan for the new address
Check which plans serve your full Round Rock address, including the unit number. Listed prices cover the first term only, and many plans renew higher, so look for a plan that renews at the new-customer price.
See Round Rock plansWhat to look for in a first plan
- A simple starting point: a fixed rate with one energy charge, no usage-based bill credit, and no time-of-day pricing.
- On each Electricity Facts Label (EFL), check the average price at 500, 1,000, and 2,000 kWh, the contract length, and the cancellation fee.
- A provider that could be a long-term home. Introductory prices cover the first term only, and many plans renew higher. Look for a plan that renews at the new-customer price.
- Solar panels, a home battery, or an electric vehicle can make plans built for them worth a look.

Request a move-in and start date
Enroll online or by phone with the provider you chose. Pick move-in (new service), not a switch, and set the start date for the day your responsibility for the home begins.
Have these ready
- The complete service address in Round Rock, including the apartment or unit number
- The account holder's legal name, email, phone number, and requested start date
- Any identity or credit information the company asks for
- A payment method, if a deposit, connection charge, or prepaid balance is due
Timing: request service once your move-in date is firm. A few business days leaves time for address, deposit, or meter questions. Same-day service is sometimes possible at an existing meter; ask about the cutoff and any fee.

Save the confirmation
Your provider sends the start request to Oncor. Check the address and start date in your confirmation. Schedule the stop at your old home separately; opening the new account does not close the old one.

Good to know in Round Rock
A Round Rock address isn't always in Round Rock. Neighborhoods such as Brushy Creek and Fern Bluff have Round Rock mailing addresses but sit outside city limits, so water comes from a utility district instead of the city. The seller or landlord can tell you which district.

Moving to Round Rock: common questions
Who is the light company in Round Rock?
Most Round Rock addresses involve two companies. Oncor delivers the power and handles outages and meters, and you can't choose it. The retail electricity provider you choose sells the power and sends the bill, and it arranges service with Oncor when you sign up.
Compare Round Rock plansShould I compare Round Rock plans on Power to Choose?
Power to Choose is the state's comparison site, and it can be a good place to find introductory deals. But many of its lowest prices are below what a provider can likely make money at, and a price like that has to be made up somewhere: at other usage levels, or at renewal. Each plan's facts label shows other usage levels, so check its price at 500 and 2,000 kWh, not just 1,000. No facts label shows the renewal price. If you want a provider that could be a long-term home, look for a plan that renews at the new-customer price.
Why renewing can cost more than signing upIs Round Rock electricity deregulated?
Almost entirely. Oncor delivers to nearly all of Round Rock, where you choose a retail electricity provider. A small area in the far northwest, around Mayfield Ranch, is served by Pedernales Electric Cooperative, where you start service with the co-op.
Who handles water and trash in Round Rock?
Inside city limits, City of Round Rock Utility Billing starts water, sewer, and garbage on one account (512-218-5460). Addresses outside city limits, such as Brushy Creek or Fern Bluff, get water from a utility district.
Can I get electricity turned on the same day?
Sometimes. Same-day activation may be possible at an existing remotely operated meter, but is not guaranteed. Ask the company opening the account about its cutoff time, any extra fee, and the confirmed start date. New construction, inspections, and field visits can take longer.
The lights are already on. Do I still need an account?
Yes, if you are responsible for electricity. The power may still be under the landlord, builder, or previous occupant's account. Arrange your own service for the date your responsibility begins. If you rent, check whether electricity is included or billed through the property before enrolling.
Apartment utilities in TexasWill I have to pay a deposit?
Possibly. The company will tell you whether a credit check or deposit is required during signup. If it asks for a deposit, check the amount, refund terms, and whether you qualify for an alternative. You do not need past electricity bills just to begin an application.
Do I need to be home when power is turned on?
Often not at an existing remotely operated meter. The company opening the account will tell you whether access or an appointment is required. For a newly built home, check with the builder that the permanent meter and any required inspections are ready.
