In an Electricity Facts Label, “TDU” stands for Transmission and Distribution Utility, which is the company delivering energy to your home and correcting outages (for example, Centerpoint in Houston and Oncor in Dallas). The TDU fees in your monthly bill cover the cost of managing power lines, checking meters, correcting outages and other services. TDU fees are always government regulated, and unlike the “energy charge” in your bill, electric companies cannot change them. You’ll find TDU charges for energy plans in the “TDU Delivery Charges” section of the Electricity Facts Label. For more info, go to HomeEnergyClub.com.
