Oncor Electric Delivery in Texas : About & Oncore customer service number

Oncor Electric Delivery, often just referred to as Oncor, is a Texas investor-owned electricity utility company based in Dallas, Texas. Oncor, which is sometimes mistaken for EnCore Energy (not currently operating in Texas), is one of the big five Transmission & Distribution Utility (TDU) companies operating in Texas on the deregulated ERCOT grid. Oncor works with over 70 different retail electric providers (REPs) to power Texan homes and businesses. The Oncor customer service number is available to assist consumers with power outages or project development, and have a specific Oncor phone number for each type of customer service enquiry. New residents moving into an Oncor service area will likely not need to contact Oncor to start electricity service.

Oncor Electric Delivery : Customer service area

Oncor has 7.5 million consumers, making it the largest utility company in Texas. Texas energy regulation restricts Oncor's operation to the transmission and distribution aspect of electricity service only. Oncor is not permitted to hold any electricity generation facilities or provide retail electricity services to customers.

With Oncor Electric Delivery strictly as a Transmission & Distribution Utility company (TDU) their role in the energy market is provide and maintain the electrical infrastructure in their service area. Oncor oversees such equipment like street lights, power lines, transformers, and electicity meters.

In the event of an outage, TDUs are more than likely the ones to contact since they are responsible for servicing the area's power lines and making any needed repairs. The only time a TDU may not be liable for power-loss is if electricity has been disconnected intentionally due to late payments by customers or delinquency. 

When electricity is disconnected as a result of billing or payment, the chosen retail electric provider (REP) is the company to contact. REPs function as an intermediary between customers and the utility companies - just as retail stores are with factories. While working with all TDUs, REPs resell energy in competitive plans directly to consumers.

Oncor Electric Delivery customer rates & tariffs

Charges for electricity delivery are regulated by the Texas Public Utilities Commission, and do not change very often (once or twice a year at most). Electricity prices, however, depend on demand and available supply, and can change regularly. For historical electricity rates, contact your REP.

For information about Oncor Electric Delivery supply charges, delivery charges, various rates and tariffs when you are serviced by Oncor, you must contact your retail energy provider directly. Please find here a list of energy providers in Texas.

In any case, a Transmission & Distribution Utility / Service Provider (TDU/TDSP) is only determined by location of residence. Switching from one utility company to another is therefore not possible unless one moves to another location covered by a different TDU/TDSP service area.

The charges originating from a TDU / TDSP (that are passed through a REP and onto consumers) are somewhat in the same ballpark but with an exception to Texas-New Mexico Power's exceptionally high monthly base fee and ¢/kWh energy rate:

Understanding your electricity bill

Oncor Electric Delivery does not issue your energy bill, only your retail electric provider does. The energy bill from your provider contains the TDSP / TDU delivery charges (a ¢/kWh rate plus a monthly base fee) set by Oncor and the supply charges owed to the retail provider for their service as an intermediary.

For any customer service enquiries regarding your energy bill, you must directly contact your chosen retail energy provider. Check out the list of energy providers in Texas to locate the customer service number for your provider specifically.
