TXU free nights and weekends: which plan do you mean?

Not under that name. On Oct. 25, 2026 we read TXU's plan page and the whole Power to Choose list. The list had one TXU plan, Free Nights & Cool Summer 12, and the state tags it as a time-of-use plan. TXU's own page names two more free-time plans that are not on the list.

Old guides still talk about a TXU "Free Nights & Weekends" plan with older prices. Many carry no date and no link to a label. If a guide gives a price for a TXU plan, ask which label it came from and when. Use the label for your ZIP.

TXU's label gives a 100% credit on the energy charge from 9:00 p.m. through 4:59 a.m. every day. In July, August and September it adds a credit of up to 25% of the energy charge, used against your daytime energy charges. That bonus has no cash value.

Read the table from the bottom up. The cheapest plain plan is the bar to beat. The label's own price sits above it, and that price already counts the night credit. So the plan only wins when your night share is well above what the label assumes. How far above is the next question.

Delivery is the part that surprises people. TXU's label passes the delivery utility's charges through on every kWh, in every hour. Our guides to Oncor's delivery charges and CenterPoint's show the amounts.

It is a good deal only if you use far more power at night than the label guesses. The check below reads your Smart Meter Texas file in your browser and adds up the power you used from 9 p.m. through 4:59 a.m. It then prices the plan on your real months.

This is an estimate from TXU's label, before taxes and city fees. It does not send your file anywhere. For the file, see our Smart Meter Texas guide.

The result shows three things. First, your share of power in the free hours. Second, what the plan would have cost on your file. Third, the share you would need to match the cheapest plain plan today. If your share is far below that, a plain plan is the safer pick.

TXU's Free Nights & Cool Summer plan is free for 8 hours a night, or 56 of the week's 168 hours. That is fewer hours than some other free-time plans, and a free hour is not the same as a useful hour. Homes use less power at night than in the afternoon.

Our guide to Reliant's free nights and weekends plans has the details on that difference.

More free hours do not always mean a lower bill. What counts is how much of your own power lands in them, and what the paid hours cost.

Not on Free Nights & Cool Summer. Its label says customers with electric vehicles, batteries or solar panels are not eligible. TXU built a separate plan, Free EV Nights, for electric car owners.

Some guides say free nights suit electric car owners. TXU's own label for this plan says the opposite. That is why the label comes first.

Open the plan's Electricity Facts Label, read five lines, and test them against your own meter file. It takes about ten minutes.

1. 1
   Enter your ZIP on TXU's site or on Power to Choose.

   Pick the plan and open its label.

2. 2
   Find the free hours.

   Look for the line that says when the credit applies.

3. 3
   Find the energy charge and the base charge.

   The energy charge is what you pay in the paid hours.

4. 4
   Find the share the price assumes.

   The label prints the percent of use at night behind its price.

5. 5
   Get your own share.

   Run your Smart Meter Texas file in the check above.

6. 6
   Save the label the day you sign.

   TXU stamps the day you open it.

7. 7
   Know your way out.

   TXU says new customers can switch free within 60 days, and that a cancellation fee applies after that. The label lists $150. The state also gives a three-business-day right to cancel after you get your written terms.

Then a plain plan is the simpler pick. A plain fixed-rate plan charges one price in every hour, so you do not have to move anything. Compare the cheapest ones at your usage, and check the label for credits and fees.
