2 min read 06-03-2025

Understanding your electricity bill can often feel like navigating a maze. One of the most common sources of confusion is the Transmission and Distribution Utility (TDU) charge, particularly for Oncor customers in Texas. This post aims to shed light on what these charges entail and how they're calculated.

What is Oncor?

Oncor Electric Delivery Company is a Texas-based electric transmission and distribution utility. They don't generate electricity; instead, they're responsible for the infrastructure that delivers power from generating plants to your home or business. Think of them as the highway system for electricity. They own and maintain the power lines, substations, and other equipment necessary to get the electricity to you. You pay Oncor separately from your electricity retailer, the company you actually choose to supply your power.

Deciphering Oncor's Delivery Charges

Oncor's delivery charges cover the costs associated with maintaining and upgrading their vast network. These charges are typically broken down into several components, which may vary slightly depending on your specific rate plan and location:

1. Customer Charge:

This is a fixed monthly fee, regardless of how much electricity you use. It covers the costs of maintaining your meter and connection to the grid. Think of it as a subscription fee for access to the Oncor network.

2. Energy Charge:

This charge is based on the amount of electricity you consume. It reflects the cost of delivering that power through Oncor's system. The more electricity you use, the higher this charge will be.

3. Demand Charge (for larger customers):

Larger commercial and industrial customers may also have a demand charge. This charge is based on the highest amount of power they use at any one time during the billing cycle. This reflects the need for Oncor to maintain sufficient capacity to meet peak demand. Residential customers typically do not face demand charges.

Factors Affecting Your Oncor Delivery Charges

Several factors influence the amount you pay in Oncor delivery charges:

Your location: Costs can vary based on geographic location and the infrastructure needed to serve that area.
Your rate plan: Different rate plans may have different delivery charges.
Your electricity consumption: The more electricity you use, the higher your energy charge will be.
Time of year: Peak demand periods, usually during the summer months, can affect demand charges for larger customers.

Understanding Your Bill

It's crucial to carefully review your Oncor bill to understand the different components of your delivery charges. If you have any questions or concerns, don't hesitate to contact Oncor directly. They have resources available to help you understand your charges and address any billing issues.
