Oncor Electric Delivery: Utility & Service Guide

Oncor Electric Delivery is a regulated Transmission and Distribution Utility (TDU), commonly referred to as an electric utility, headquartered in Dallas, Texas. As the largest energy delivery company in the state, Oncor maintains more than 144,000 miles of power lines and serves more than 13 million Texans. Its core responsibilities include:

• Infrastructure maintenance: Oncor owns and maintains the poles, transmission towers, substations, transformers, and smart meters that keep electricity moving Oncor’s Texas service territory/service area.
• Energy delivery: It transports electricity from power plants over high-voltage transmission lines, then distributes it through lower-voltage neighborhood lines to homes and businesses.
• Emergency response and repair: Oncor crews handle equipment upgrades, storm repairs, and vegetation management to help prevent outages. If your power goes out, Oncor is the company that restores service, regardless of which Retail Electric Provider (REP) you choose.

Although you can shop around for REPs in deregulated areas of Texas, you cannot choose your own TDU because they are assigned by location.

Oncor serves more than 400 communities across more than 98 counties in Texas. Its footprint stretches from the Dallas-Fort Worth metroplex to parts of West, East, and Central Texas. Here’s a closer look at the deregulated cities within their territory:

Resident that live within the Oncor service area see on average an electricity rate of 15.2¢.

Texas electricity bills include both an energy charge (cents per kilowatt-hour, or kWh) from your electricity provider and delivery fees from your TDU. Delivery fees are approved by the Public Utility Commission of Texas (PUCT) and passed through to customers by their chosen provider, meaning every Oncor customer pays the same delivery fees regardless of who their REP is.

As of February 2026, residential customers in Oncor’s territory pay:

• A flat monthly delivery charge of about $0.06
• A usage-based delivery charge of $4.23 per kWh

However, these fees are typically updated a few times per year. In fact, Oncor requested permission from the PUCT and 210 cities to increase its base rates in mid 2025. If approved, a residential customer using 1,000 kWh per month on a plan priced at 15 cents per kWh would see a roughly 3 percent increase in their overall bill, or about $4.64 more per month. The total impact on each customer’s bill will depend on how much electricity they use each month.

Why Oncor Delivery Charges Are Increasing in 2026

On January 29, 2026, Oncor filed an unopposed settlement requesting approval of a $6.975 billion annual revenue requirement, representing an 8.8% increase over adjusted revenues.

Under the proposed settlement:

• Residential customers using 1,000 kWh/month would see about a 3% bill increase, or roughly $4.64 per month, down from the original 4.7% request.
• Approximately 45% of the original rate increase request was driven by storm restoration costs, with Oncor averaging 31 major storm events per year over the past three years.

Beyond customer bills, broader grid demand is also shaping Oncor’s long-term investment strategy.
