Programs are open to any resident of Oncor's service territory, regardless of their Retail Electric Provider (REP).  The map below shows Oncor's service area in Texas.  This map is provided for reference only, as customers located within this service territory may or may not recieve electric service from Oncor.

If you aren't sure if you are an Oncor customer:

  • Look on your electic bill: The company you call when the lights go out is your Transmission & Distribution Utility (TDU).  If your bill lists Oncor as your TDU, you may be eligible to participate.  Oncor customers can also be identified by the Electric Service Identifier number (ESI ID) printed on their electric bill or meter as shown below:
