Ever wondered why your Texas electricity bill includes a line for “TDU delivery charges”? These fees cover the cost of safely delivering power to your home through the poles, wires, and meters maintained by your local utility company.
Though they appear on your bill from Amigo Energy, the charges themselves are set by your regional Transmission and Distribution Utility (TDU) and regulated by the Public Utility Commission of Texas (PUCT).
Understanding these charges helps you see where your energy dollars go and how to better compare plans.
What is a TDU Charge?
A TDU charge is the regulated fee you pay for the delivery of electricity to your home, which helps cover the cost of maintaining the poles, wires, and meters managed by your local utility.
What Does “TDU” Mean?
TDU stands for “Transmission and Distribution Utility.” TDUs in Texas help maintain the physical grid, like everything from the power lines to the meters outside your home. Without them, energy providers like Amigo Energy wouldn’t be able to deliver electricity safely or reliably.
Major TDUs in Texas include:
- Oncor (North Texas)
- CenterPoint Energy (Houston area)
- AEP Texas (South and West Texas)
- Texas-New Mexico Power (TNMP) (various smaller markets)
Your TDU is assigned based on where you live; you can’t choose it like you can your retail electricity provider if you live in a deregulated energy area. Regardless of which energy provider you select, your TDU remains responsible for physically delivering the power.
How TDUs Keep the Texas Grid Running
TDUs work behind the scenes to keep electricity flowing. They repair downed power lines after storms, manage outages, and maintain the equipment that connects homes to the state’s power grid.
They also coordinate with ERCOT (Electric Reliability Council of Texas) to balance electricity supply and demand, ensuring stable service across the state. These utilities are regulated by the Public Utility Commission of Texas (PUCT), which oversees their fees, reliability standards, and infrastructure investments.
Because TDUs handle the physical delivery of power, all customers in a given area pay the same delivery charges—no matter which electricity provider they choose.
Why Do I Pay TDU Delivery Fees?
When you pay your electricity bill, you’re covering more than just the energy you use. Your total cost is divided between what you pay Amigo Energy for your electricity supply and what you pay your local TDU for safely delivering that electricity to your home.
Delivery vs. Energy Supply Costs
Electricity in Texas comes from two separate entities working together. Retail electricity providers (like Amigo Energy) purchase electricity from the wholesale market and sell it to customers, while Transmission and Distribution Utilities (TDUs) handle the delivery of that electricity through the grid.
Your TDU charges appear as separate line items on your bill and cover the cost of maintaining poles, wires, and meters. These fees are regulated by the PUCT and apply equally across all retail providers in your service area. Amigo Energy doesn’t mark up or profit from these delivery charges.

How TDU Fees Work
TDU fees are designed to recover the costs of maintaining and operating the power grid. The Public Utility Commission of Texas (PUCT) reviews and approves these rates to ensure they’re fair and reflect actual expenses.
Charges generally include two components:
- A fixed monthly charge: Covers basic service and meter maintenance.
- A variable per-kilowatt-hour (kWh) charge: Reflects the electricity delivered to your home.
For example, Oncor delivery charges may be a fixed fee of less than $5 per month plus a few cents per kWh delivered. CenterPoint Energy TDU fees are similar for Houston-area customers.
These rates can change periodically when TDUs request updates to cover grid improvements or storm recovery costs, but all adjustments must be reviewed and approved by the PUCT.
How to Read TDU Charges on Your Bill
TDU delivery fees can be easy to miss if you don’t know where to look. Here’s how to identify and understand them on your electricity bill.
Locate the TDU Delivery Section on Your Bill
Your Amigo Energy bill lists your TDU charges. Look for a line labeled “TDU Delivery Charges,” “Delivery Fees,” or “TDSP Charges.” This section lists what you pay your local utility to deliver electricity to your home.
Review the Two Types of Charges
- Fixed monthly charge: A flat fee for basic service, meter reading, and grid access.
- Variable usage charge: A per-kilowatt-hour fee based on how much electricity you use.
By taking a few minutes to review these details, you can better understand how your total bill is calculated and make more informed choices when comparing electricity plans.

5 Ways to Manage or Lower Your Total Electricity Costs
While TDU delivery charges are fixed and regulated, there are several ways to reduce your total electricity expenses.
- Choose the right plan type: Fixed-rate plans keep your rate consistent month to month, while variable-rate plans fluctuate with market prices. Compare both through Amigo Energy’s Texas electricity plans to see which fits your usage. Learn more about fixed vs. variable rate electricity plans.
- Track your energy use: Use smart meters or energy-monitoring apps to spot patterns in your consumption. Knowing when and how you use electricity can help you make targeted changes that lower your bill.
- Shift high-usage activities to off-peak hours: Run dishwashers, washing machines, or other large appliances when grid demand is lower (typically late at night or early in the morning).
- Improve your home’s energy efficiency: Seal gaps around doors and windows, upgrade to LED bulbs, and service your HVAC system regularly. Small upgrades can significantly reduce overall usage.
- Understand your provider’s role: Be sure to know the difference between utility providers vs. energy companies. Understanding who handles what can make it easier to interpret your bill and control your costs.
These steps won’t change your TDU delivery rates, but they can help you take control of the portion of your bill that’s within your power to manage.
