What You Need To Know About The TXU Free Nights and Solar Days Plan (Updated 2022)


Update: Read about the new TXU Ultimate Summer Pass 12 Plan

TXU was the first major electric provider in Texas to offer time of day pricing to the public with their introduction of the TXU Free Nights program in Texas.  The plan was an immediate hit with consumers.  The company later created a Free Weekends plan under the banner of TXU Energy Right Time Pricing.  By the summer of 2013, the company had enrolled nearly 100,000 customers in free electricity plans.

TXU’s latest time-of-day pricing plan is TXU Energy Free Nights and Solar Days plan.  Under this plan customers get free electricity from 8:00p.m to 5:00a.m.  The idea with the Free Nights and Solar Days plan and similar plans offered by TXU and other electric companies is to shift consumption away from the 3pm to 7pm window that sees the most stress put on the state’s electric grid.  This is the most expensive time for electricity providers to procure electricity.

Other providers have since introduced similar plans.  They all attempt to address a major challenge that the Texas electric grid deals with. Capacity within a grid must be sufficient to cover peak demand periods.  In Texas, peak demand is typically during the heat of the day when air-conditioners in homes and businesses are at maximum usage.  Other times, particularly at night, most of that power generation capacity sits unused. This is why wholesale electricity prices plummet at night.  Anything that spreads electricity usage out more reduces strain on the grid.

How much does TXU charge per kWh during peak hours?

During the non-free hours, as defined by the plan, there is an energy charge of 19.8 cents per kWh* if you live in the ONCOR service area which includes most of Dallas / Fort Worth and other parts of the state.  In addition to this there is a TDU passthrough charge.

Predicting what your actual all-in rate will be can be tricky since much depends on not only how much electricity you use but what times of day you use it.

TXU free nights solar days EFL February 2022

As a guideline, TXU’s Electricity Fact Label (EFL) dated February 16, 2022 establishes an average price per kWh of 14.9 cents.  This number makes the assumption that you use a total of 1,000 kWh hours.  It also makes the assumption that a certain percentage of your usage falls within the “free nights” window as defined by the plan.  Of course, your results may vary.  If you can shift more of your usage into evening or night time hours, you could lower your effective rate.  A greater percentage of usage during the non-free hours would result in a higher effective rate.

Is TXU free nights worth it?

TXU’s time-of-use plans are best suited for consumers who don’t use a lot of their electricity during hours of peak demand or consumers who are willing to change their habits by shifting power intensive activities such as laundry and dishwashing to the hours designated in the plan as free.

Some recommendations TXU makes for getting the most out of the plan’s free hours:

  • Using timers to control the start time of major appliances such as washing machines and dishwashers
  • Making use of programmable thermostats
  • Charging portable devices during free hours
  • Running pool pumps during free hours

TXU also offers tools using your smart meter to help you analyze your electricity usage and identify ways to lower your electric bill by shifting some of your usage to the free electricity times of day.

What time does free nights start for TXU?

The free portion of the plan covers the hours of 8:00p.m to 5:00a.m.

Where does the solar power come from?

As the name implies, the non-free electricity portion of this plan is based on pricing for solar energy.   By choosing this plan, you are paying to support solar power facilities.  In reality, if you switch to this plan, your power will be coming from the same grid as before.  This grid has electricity from a mix of sources that includes both renewable and non-renewable sources.

Identifying any particular kilowatt of electricity that comes off of the grid as solar would be a little like trying to guess what cows your gallon of milk came from.  The power for this plan is considered solar because TXU purchases solar credits from solar farms to equal the amount of power you use during the day.

  • TXU are so smart asses!!! Just pick the company with the cheapest rate. It doesn’t matter what company it is. They just administer your account, but Oncor is the one that actually delivers the electricity!!!

  • I cannot see how we would benefit with this plan.

  • I do not see how we would benefit from this plan,

  • We just got our first bill under the free nights program and we would have saved $100 even with the increase in per kilowatt rate. What they don’t tell you is there is
    Something called a TDC cost that in regular plans get rolled into the regular rate. The bundling disappears in the new plan, so they add it to your bill. Ours was $120 added to our bill. False advertising! You do not save money!

    • Jason-

      Thanks for posting! We keep hearing more and more horror stories about TXU’s Free Nights Plan. It’s amazing they are still running the program. Please spread your words of caution!

    • It mentions the TDC (TDU Delivery Charges) at the top of their electricity label. The electricity is free, the charge for delivery (from Oncor, not TXU) is still there, approx 3.5 cents where I live.

      “TDU Delivery Charges Per Month and TDU Delivery Charges Per kWh will be passed through to customer as
      billed from the Transmission and Distribution Utility (TDU).”


    • Yes they ill cut you off in a heart beat that’s why i moved on!

  • Eddie-

    Thanks for posting about your bad experience with TXU. It looks like you’re a victim of yet another trick by TXU to squeeze more money from you.

    You might take a look at Trieagle for better rates and no deposit. Actually, just about every electric company has better rates than TXU!

    Good luck!

  • It will benefit a small sliver of society financially, that being people that get home late at night and are not around during the day. Some people close to this schedule will push more usage to late at night to save a few dollars. The plus side of this plan being voluntary peak load-shedding. The negative side being that if you sign up for the plan, but don’t take advantage of it, you’ll get yourself into trouble.

  • Signed up last on 06/28/2013. I received my disclosures one week later. They failed to disclose I had to have over 2000 KWs in order to get the 14.4 rate and free nights. Under 2000 KW’s and there is an account fee of $9.95. The total per KW’s is 18.9. The whole thing is gimmick.

    • I use the dishwasher and the washing machine and the dryer only after 8 p.m. and I DO save money!!!!

  • Well, I only use air conditioning and heat at night so this would be a saver! My electric bills in the summer are around 60 bucks.

    • That’s what I was thinking when I signed up for the free nights. That I would save big on AC costs. However my first bill was well over 100 dollars more on this plan. Part of my bill says my average charge per KW is 14 but they were actually charging me 19 per KW. Guess I missed that little detail of the plan, quickly switched back to my old plan.

    • I have been on the free night for three years. I love it but I have to wait to cook and do laundry after 8 PM. That is the main downside. In June July and August 2019, my electric bill averaged $45.00 per month. Now during the winter, it is a little worse. Because from 5 AM till I get up at 8 AM the heater comes on and that costs me when I’m not even awake. The AC in the summer does not have a tendency to come on from 5 AM till 8 AM like the heater does. My solution is to wake up at 5 AM daily to shut off the heater. That would not work for most people but I do it only on the colder nights. Of course, where you set your thermostat matters much. The discipline demanding part is doing without the AC and Heater if possible from 4 PM to 8 PM. When I screw up, it is during the 4 to 8 PM time frame.

      • I failed to mention., I am in a one-bedroom apartment bottom floor. Seriously all summer long — $45.00 per month. I did notice I pay 18.6 cents per kilowatt-hour, not 17.6 cents like the documentation above shows. Hmmmm. May be time for a refund.

  • Moved here from OK over 5 years ago and just picked a company because I didn’t know about the difference. TXU was the first company I chose. The first year or 2 my bills were high but I thought that was just the difference from OK to TX. Then when I got out my contract my bills went down so I just left it as is. But in the last 8 months my bills doubled. So I callled to cancel but ended up getting the free nights plan. My bill has been averaging for the months at $170 for the Summer. Just got my first bill on the free night and it was $158 !!!.. so I just saved $20 !!!! Needless to say I just changed to Just Energy ( Amigo ) for .09 per kwh…. We had to all most live like hermits to even save that much which was crazy !!! Maybe if my boyfriend didn’t work from home it would not have been so bad but geesh…. Again I’ll say TX has no sales tax but they will get you somewhere else….. UGGGGHHHHHHH TXU needs to kick rocks and get it together and it seems they are only staying in business de to loyal customers or older people who don’t like change…

  • I must of been a dummy to be thinking that this was a deal, man did I get the screws big time. I have been with TXU for better than 12 years. I switched to this night plan, and being on average billing all these years I was paying around 170-200 a month. I just got my last month bill for Nov. 2013 and my bill is 298.00. What a rip off I was suckered into. I will attempt to call TXU and see if they are willing to change my contract or I will be switching to someone else.

  • I have been with TXU for more than 6 years and I have 2 accounts with them. Within the last months I have been so dissapointed in TXU. They don’t want to work with you and I just had to pay a $170.00 deposit and they would not work with me and I have been a loyal customer for more than 6 years!! I’m ready to move to a new electric company.

  • Same old TXU, I was a loyal customer until 12 years ago, then during a move they tried to screw me over. After several hours of bad customer phone support I dumped them and swore never to use them again. Then I hear hear about the “night and weekends” , “deal” and think, ” hmm maybe the finally changed their tune”. So I do a little digging and find this thread, lol wow I guess a leopard can’t change it’s spots after all, and saved myself the hassle of dealing with them.

  • All of your stories are scary. I have never had an issue with Txu. I have the free nights plan and it’s perfect. I was well informed of all I was getting myself into. I chose the plan because I was told, if used properly and fit your lifestyle it’s great. My roommate works 3 jobs so is barely home. I work full time and go to school part time so when I’m home I don’t use much electricity. We wait until after 9 (when it’s free) to use the a/c, dishwasher, and do our laundry. We also make sure we wake up early enough to turn off the a/c and other energy guzzlers before 6am (when it’s no longer free). This has been working like a charm and we have not had a bill over $37 in our 2 bedroom apartment. AND ITS AUGUST! I love the free nights plan. Maybe you just have to work the ropes!

  • I post my last bill (Aug/17/2014-Sep/16/2014) of the TXU free night plan for comparison. I live in a 1br apartment, 600 sqft. I turn on the air condition only in 9pm-6am everyday. The indoor temperature increases on day but is barely over 85. I need to use fan in the afternoon. I cook, vacuum, launder, distill water after 9pm. I think this plan does save me a bit. Now I’m planing to buy some growing lights to grow vegetables during the night!

    • This is about the same bill I have for the past year now when I switched to this plan last summer of 2015. I think this plan works best for people who gets home late at night. I get home at around 10pm (I leave for work around 1pm) and that’s when I do all my laundry, dishes, meal prepping/cooking, vacuuming….

    • If you’re still using TXU free nights solar days plan, please post your bill again. It would benefit us who are considering the switch, to see how much savings, if at all, to have Free Nights but pay double for Days

  • I don’t like the higher base charge TXU has on the free nights plan and the higher kWh charges for daytime use, but I save with the plan, regardless, since I put my 50-gallon tank electric water heater on a timer that turns it on only during the free period. I also turned its thermostats up to 150 degrees, since I don’t need to worry about children being accidentally scalded. It lasts me through the days. I wash and dry clothes and dishes at night. In the winter, I burn gas for daytime heat and use electricity for nighttime heating. I use other energy-saving methods also, so my bill is much lower than before I switched to free nights. I just renewed my contract for another two years and would have gone for three or four years if that had been offered. Bottom line is that for you to benefit from their plan, you need to have a good plan of your own.

  • Free is a misnomer. You still pay the ONCOR delivery charges on the “free stuff” and a very high rate on the other. Usually 75% or more than you can get if for. I am a Independent seller of electricity and I have audited bills on the free program and I can always bet the monthly total on the TXU bills. There is no free electricity – You are being deceived with advertising. They have to buy it so you know they are not giving away at a loss.

  • Hey people try cerro energy I pay 190 in the summer and about 60 in the winter and the best thing is no hidden fees.I pay 0.8 per. Kw. These company that offer free this free that are lying. Remember nothing is free. Good luck

  • I have solar panels and was reimbursed by TXU at wholesale price. Then I signed up for Free Nights. TXU then cancelled my reimbursement for elec generated by my panels. Can’t have two plans is the answer I get and besides the savings at night equal the savings of the solar panesl. I am not happy about this let alone the up front cost of installing solar panels. You can’t have more than one plan with TXU. Pretty slick, I generate electricity for my neighbors but not for me……. ps They don’t pay either.

    • What was your electric bill like with the panels and free nights?

  • The free nights is a rip off. I can’t always wait until the night to do things. It was way expensive. It sounds good, but the rate is more during the day. I stayed with TXU but switched to the TXU Energy e-Saver 10 plan. It’s a LOT cheaper! Plus, I don’t have to wait until the night. I get the same low rate any time of the day.

  • On Sept 2014 someone posted their bill with detailed charges and added fees. This really helps us who are considering the service or switch to Free Nights Solar Days program. If anyone has the service and can post your recent bill detailed charges, please help us by doing that! Thank you!!
