Oncor delivery charges and service area

What Oncor is

Oncor Electric Delivery is a transmission and distribution utility (TDU): it owns the poles, wires, substations and meters in its territory, connects homes and restores outages, but does not sell electricity. Since Texas opened its market in 2002, homes in Oncor's area buy electricity from a retail electric provider, which bills both its own energy charge and Oncor's delivery charges. Oncor operates inside ERCOT, the grid that covers most of Texas.

With 3,545,814 residential customers in 2025, Oncor is the largest of the 6 Texas delivery utilities and one of the largest distribution utilities in the country. It also served 528,368 commercial and 10,613¹ industrial accounts.

What delivery costs a home

EIA's annual census reports what each delivery utility billed, through the retail providers, for its service. Oncor's residential delivery revenue averaged 5.64¢ per kWh in 2025, up from 5.19¢ per kWh² in 2024 (+8.7%). At the average use of 1,106 kWh a month, that is about $62.35 of a typical bill. Businesses paid less per kWh because they use more power at higher voltage: 3.90¢ per kWh for commercial and 0.97¢ per kWh¹ for industrial customers.

This average includes Oncor's monthly customer and metering charges spread over kWh, so it is not the same as the per-kWh delivery charge in Oncor's tariff. The approved charges are set by the Public Utility Commission of Texas in Oncor's rate cases and periodic adjustments, and each plan's Electricity Facts Label shows how a retail provider passes them on.

What Oncor customers paid in total

Because every home in Oncor's area buys from a retail provider, the all-in price depends on the plan. EIA reports what each provider collected from its residential customers over the year, delivery included. Across all Texas retail providers the residential average was 17.23¢ per kWh in 2025. The two largest, Reliant Energy Retail Services and TXU Energy Retail Co, LLC, averaged 18.38¢ per kWh and 19.36¢ per kWh; among the 38 providers with 10,000 or more residential customers, averages ran from 8.03¢ per kWh to 20.86¢ per kWh¹. These are past averages across all of each provider's plans and areas, not offers.

Where Oncor delivers

EIA's service-territory records place Oncor in 99 Texas counties, from the Dallas-Fort Worth area to Waco, Tyler, Midland and Odessa. In all but 1³ of them at least one other utility, usually an electric cooperative or a city utility outside the competitive market, also reports customers, so a county alone does not tell you whether a home is on Oncor's wires. Homes served by a co-op or a city utility such as Denton's or Garland's are not part of the competitive market and cannot choose a provider.

Outages and meters

Oncor's customers averaged 232 minutes without power in 2025 including major events (more than the Texas average of 225 minutes), and 67 minutes on ordinary days, with 1.55⁵ interruptions per customer; Oncor reports under a method other than the IEEE standard, so compare it with other utilities with care. All its residential meters are advanced meters (100.0%⁶), which is what lets retail providers offer time-of-use and other plans. The Texas state page puts Oncor alongside the rest of the state's utilities.
