There are 3 easy ways to request underground service:

1.     Submit a request using the Oncor New Construction Form on Oncor.com.

2.     Call the Oncor New Construction Department at 888-222-8045

Hours of Operation: Mon-Fri 7am - 7pm & Sat 8am - 12pm

3.     For multiple locations, please submit all of the information via the Builder Request Email Form and send to c3ncmc@oncor.com.  

The request can be made:

1.     After the main Oncor infrastructure to your subdivision or location is completed and energized.

2.     Before you install driveways, sidewalks, paved parking lots, retaining/concrete walls, sprinkler systems, etc.

If the location has or plans to have an obstruction that could be in the path of the underground, Oncor will require the customer to provide and install the raceway for the service to Oncor specifications.

3.     When your location is almost complete (no more digging planned).

Please review the Electric Service Guidelines for requirements.

Oncor will take several actions to start the process of installing your underground service, including sending a crew to perform the work, targeted within 10 business days.

 Weather conditions and storms can impact this timeframe and the resources needed to complete this request.

The 10 business day timeframe also assumes that the site is ready for underground, the meter location is marked/addressed, and the pathway is free of obstruction. Any issues with site readiness will likely result in the order being canceled and require the process to start all over again. 

1. Ensure the underground pathway is clear of any and all debris, making it easy for our crews to mark and complete the work.

2. Ensure the entrance to pathway is accessible to our crews.

3. Clearly mark the address on the meter base or meter location, assisting our crews in making sure the underground is installed at the correct location. If you have the ESI ID, you can mark that as well!

Note: Oncor does not bore under obstructions (i.e. driveways, paved parking lots, retaining/concrete walls). This may cause the underground order to be cancelled.

If the location has or plans to have an obstruction that could be in the path of the underground, Oncor will require the customer to provide and install the raceway for the service to Oncor specifications.

Please review the Electric Service Guidelines for requirements.

Customers must have the path completely clear for the crew to safely dig the trench. Any and all debris, including trash must be removed.

No, customers do not need to call 811. Oncor will contact line locate prior to the installation. The time required is already factored into the 10 business day target.

Oncor targets the completion of the underground service order for 10 business days after it is requested (weekends and holidays are excluded). However, weather conditions and storms can impact this timeframe and the resources needed to complete this request.

The 10 business day timeframe also assumes that the site is ready for underground, the meter location is marked/addressed, and the pathway is free of obstruction. Any issues with site readiness will likely result in the order being canceled and require the process to start all over again. Once your worksite is ready for underground service, please contact Oncor New Construction Department at 888-222-8045 to reschedule.

Underground service installation must take place before a Move-In request--the final step in establishing power at a new location—can be completed. 

Please work with your chosen retail provider to ensure that a move in request has been sent to Oncor by visiting www.powertochoose.com.

Once the underground service order has been completed and Oncor has received the move-in request, Oncor will activate service based on the date that you have agreed on with your retail provider.

Please note separate city and/or county inspections could be required before power can be activated. Click here for more information on city inspection requirements. 

Common reasons include (but are not limited to):

1.     The pathway is not clear of any and all debris.

2.     Location was not able to be found or location is not clearly marked (technicians are not clear on where to run the underground).

3.     Customer facilities were not ready (i.e. meter base location not marked).
