What are Transmission and Distribution Utility (TDU) Charges?

TDU (or TDSP) charges cover the cost of maintaining the wires that deliver electricity to your home from power generation sources. You will notice line items on your bill called "TDU Delivery Charges" and "TDU Meter Charges". These are the charges associated with the servicing and delivery of electricity to your meter.

How are TDU Charges determined?

TDU charges are calculated based on your electricity consumption and the rates set by your TDU. The charges are typically broken down into a usage-based fee and a standard monthly flat fee. These costs are the same regardless of your electricity supplier and are passed through to you without any markup. These rates must be applied exactly as approved by the Public Utility Commission of Texas (PUCT). GoodCharlie is not responsible for determining TDU charges, and thus has no control over the charges.

How and when do the TDU Rates Change?

Typically, the TDU delivery rate changes twice a year in March and September with the approval from the Public Utility Commission of Texas (PUCT). The rate changes reflect the change in cost of maintaining and operating the transmission and distribution infrastructure. This means that during the term of your agreement, the total average price you pay per kWh may increase or decrease, but your contract rate (GoodCharlie's Energy Charge) will remain unchanged. You can find your contracted energy rate on your Electricity Facts Label provided to you at the time of enrollment.
