TDU charges are part of your monthly electricity bill in Texas that pay for the delivery of power from the plant to your home, management and maintenance of power lines, and the meter and measurement of your home’s electricity consumption.
TDU stands for Transmission/Distribution Utility. TDUs are the organizations that are responsible for the delivery of electricity from the power plant to your home or your business. They manage and maintain power lines, as well as the meter on your home that measures your home’s energy usage. TDUs may also be referred to as Transportation and Distribution Service Providers (TDSP).
When trees fall into power lines during a bad storm, your TDU is responsible for repairing that line and restoring electricity to the area that lost power as a result of that fallen tree.
How Are TDU Charges Determined?
Charges from TDUs are approved by the Public Utility Commission of Texas (PUCT) and will appear as a line item on your bill next to the phrase “TDU charges,” TDU delivery charges,” or “TDU pass-through charges.”
TDU charges are adjusted twice per year, every March 1 and September 1. View the latest TDU charge updates.
TDU charges change because the TDUs are allowed to recuperate all of the costs incurred from the services they provide. If Houston experienced several severe hurricanes that required Centerpoint Energy to provide more maintenance than normal, they would likely need to increase their charges for a certain time.
