Historical TDU (TDSP) Delivery Charges
Updated: 09/04/2024
Understanding TDU Delivery Charges
In Texas, your power bill comes from two distinct entities:
You receive an energy charge from the REP, which varies based on the electricity plan you select. This gives you some control over your energy costs. Meanwhile, the delivery charge, also known as the passthrough charge, is billed by the TDU. This charge is based on the TDU's service territory, and you don't have control over it.
Texas has six TDUs, each responsible for a specific area: Oncor Electric Delivery, AEP Texas Central, AEP Texas North, CenterPoint Energy, Texas-New Mexico Power (TNMP), and Lubbock Power & Light (LP&L).
You can only change your TDU by moving to a location served by a different utility company. However, you can choose your retail electric provider, and there might be several plans available from the same REP.
- Retail Electricity Provider (REP): This is the company that sells you the electricity.
- Transmission and Distribution Utility (TDU): Also known as Transmission and Distribution Service Providers (TDSP), these companies manage the local power grid and charge for delivering electricity to your home or business.

Updated TDU Delivery Charges for All Service Territories
What are electricity delivery charges? TDU delivery charges consist of a fixed monthly fee and a variable fee based on the number of kilowatt-hours delivered.
These charges are revised twice a year, in March and September, with approval from the Public Utility Commission of Texas (PUCT). In addition, TDU charges may be adjusted at other times throughout the year depending on market conditions, though these adjustments are not scheduled.
Retail electric providers are prohibited from adding a markup to delivery charges. The rates must be applied exactly as approved by the PUCT.
