What is a TDU charge?

All TXU electricity plans include a TDU charge.

Watch a short video about what TDU delivery charges are and how they can affect your electricity bill.

TDU stands for transmission and distribution utility. They are responsible for electricity getting from the powerplant to your home. They are a completely separate company from TXU, as a result TXU have no control over the charges that appear on your bill.

A "Tiered rate plan" is a rate plan where the amount you pay per kWh for electricity increases as the quantity of electricity consumed increases. Generally there is a baseline allowance of a certain number of kWhs (kilowatt hours) per month that are charged at a cheaper rate, and then usage above this allowance is charged at a higher rate.

A "Time of Use" rate plan is an electricity plan where the amount charged per kilowatt hour (kWh) is determined by the time of the day and the season of the year in which it is used.

Time-of-Use plans will typically have "peak" periods with higher rates and "off peak" with lower rates.

The idea behind time of use billing is to get customers to use less power at peak periods (when most people use a lot of power). Peak periods put a lot of strain on the grid. This is why time of use billing is being implemented by all major utilities. It is an attempt to encourage consumers to help spread out the load, and thus reduce investment needed to support brief periods of extremely high usage.

If customers can adjust their habits to use appliances at non-peak times they have to potential to significantly lower their electricity bills. Although, as power at peak times is much more expensive, if you continue to use lots of power at peak times your bill could be higher.

How do I work out if I am on the cheapest TXU rate plan for my usage pattern?

If you can limit your usage during peak times then a time of use plan is probably going to end up cheaper. Although, if you cannot limit usage during peak times, then a tiered plan is the way to go.

Big utilities are all making the switch to time of use billing. So, it could be a good idea to get in the habit now of using less power during peak times (3-8pm on weekdays).

To do an exact comparison on how much you would save from switching plans requires collecting your detailed usage data for the last 12 months. This is known as Interval Data and sometimes also called Green Button Data.


Interval Data
Green Button data


Interval or Green Button data is your electrical usage data for the last 12 months in one hour (or even shorter) intervals. This data is available from your utility provider.


HINT: Often the easiest way to get this data is to ask a solar company to get it for you, as they need to retrieve this data anyway in order to properly estimate the costs and savings that might be available to you by installing solar panels in the TXU area.

How do I get my interval data for the last 12 months?

This data is available from TXU. They are required by law to send it to you. Although, this is not the easiest way to obtain the data.

There is also a website called that allows you to get this data for $15 (they have an electronic interface to TXU).

However, if you own your home and it is a single family dwelling, then a really good way to get this data for free is to request solar quotes from local solar companies.

Generally, solar offers much bigger savings than simply swapping rate plans (as the plans are designed to give the same overall cost to average consumers) and a solar designer will usually need to get the same interval data to work out what size solar system would cover your bill, and to forecast savings accurately for you.

Solar companies will usually retrieve and analyze your interval electricity usage data for free in the hope of winning your solar business.

How much can I save per month by swapping to my cheapest plan?

For most people the amount you can save by swapping plans is minimal because rate plans are designed to work out roughly the same in terms of total costs for consumers with average consumption patterns.

In most cases savings will be between $0-$15 per month, but they could be much larger for high energy users or for homes and businesses with non-typical usage patterns.

This limited upside for a rate plan change is why most people in Texas who own their homes are now looking at solar as the best method to reduce their power bill.

Even moderate electricity consumers with a monthly TXU bill of only $150 (with suitable homes) can often save $50 or more (even after the solar repayment) every month by going solar, and in many cases they can almost eliminate their power bill after the 7-8 year payback period. The savings over the lifetime of the system (25 years) is usually tens of thousands of dollars.
