Moving to the Dallas area (i.e. 75217, 75211, 75228, 75243) and need to start electricity service with Oncor Electric Delivery?

Although Oncor Electric Delivery is the main TDU in this area, TNMP is the other utility that serves communities in surrounding areas (Lewisville, Gatesville, and surrounding communities). When in doubt, your best bet would be to contact either utility company to ensure you start out on the right foot setting up an electricity service for your new home. Start by calling Oncor's customer service number listed below to find out whether they provide service to your address. If, by chance, Oncor doesn't cover your location, give TNMP's customer service line a call to confirm (or another utility until you can confirm which one covers your home).

  • Oncor Electric Delivery's customer service: 888-313-6862
  • Texas New Mexico Power's (TNMP) customer service: 888-866-7456
  • CenterPoint Energy's customer service: 800-427-7142
  • AEP Texas North's customer service: 877-373-4858
  • Sharyland Utilities's customer service: 866-354-3335
  • AEP Texas Central's customer service: 877-373-4858

Another easy method to understand which TDU produces your electricity is to reference the ESI ID / ESID on the electric meter for your new address. This number is anywhere between 17 and 22 digits long, but all we need are five of those (digits 3 to 7) to know which utiltiy company the meter belongs to. The first two digits will be a ´´10´´ followed by the five digit TDU identity code. [For example: ´´10number86034669210]

After finding out which utility company covers your area, the only other step is to decide which Retail Energy Provider (REP) to go with! Once decided, starting service is pretty straightforward. To open an account in your name you will simply need to call your favorite REP and provide:

  • Your exact address (including your street address, unit number, city/town, and zip code)
  • Your full name and contact information (phone number, email, address)
  • The date you require service (in other words, the date you move in)

Many REPs require a security deposit to activate accounts for new customers, so you may also be asked for your Social Security Number (SSN) in order for the provider to perform a credit check.

For a head-start, below are a few of the most recognized electric companies in Texas:

For issues experienced by customers, the Public Utility Commission of Texas wesite maintains a fairly current listing of formal Complaint statistics for Energy companies. The list ranks from the highest number of complaints to lowest so perhaps working from the bottom of the list to the top may be the most time-efficient way to go about finding your next provider.

Oncor Electric Delivery customer service

Your local electric utility is responsible for responding to power outages or electricity-related emergencies. Contact them immediately if your power goes out unexpectedly, or if you witness a dangerous situation involving downed power lines or any potential hazard (such as branches touching power lines). In most cases, for all other concerns, including questions about your bill, payment, or any other issue, call their customer service number.
