Understanding Oncor in Texas

What Is Oncor's Role in the Texas Electricity Market?

Oncor delivers electricity across high-voltage transmission lines, substations, and neighborhood power lines. Oncor does not sell retail electricity. Consumers choose their Retail Electric Provider (REP) for energy supply; the REP's EFL and terms show how Oncor delivery charges are reflected in an offer.

How Oncor Delivery Charges Are Calculated on Your Bill

This directory illustrates the tariff inputs for Oncor. A plan's EFL and terms show the energy, delivery-charge, and credit treatment that applies to that offer.

Sample Monthly Delivery Calculation at 1,000 kWh:

Customer Base Charge:$4.23

Volumetric Charge (1000 kWh × 5.1257¢/kWh):$51.26

Directory Tariff Calculation:$55.49

This calculation applies the tariff inputs above at 1,000 kWh. Review a plan's current EFL and terms for the estimated bill and how delivery charges or credits apply to that offer.Read our full calculation methodology →

How to Report an Outage to Oncor

If your lights go out, do not call your retail electricity provider. Retail providers do not own equipment or dispatch service trucks. Oncor Electric Delivery Company LLC is solely responsible for restoring power across its network.
