TXU Ultimate Season Pass: How It Works & the Catch
Quick answer: The Ultimate Season Pass is a 12-month TXU plan. It takes 50% off TXU’s energy charge in January, February, July and August, and 25% off in March, June, September and December. April, May, October and November get no discount at all. Here’s the catch: the discount never touches the $9.95 monthly base charge or your utility’s delivery charges. When we ran TXU’s own numbers (Electricity Facts Label pricing dated Aug 1, 2026), this plan cost more than a typical simple plan every month of the year, even in the half-off months. There’s also a $150 fee if you leave early.

Watch TXU’s ad, then let’s unpack the real costs.
Utility vs. provider: what the discount actually touches
Your electric bill has two sides, and this plan only discounts one of them.
Your provider (TXU) sells you the electricity. On your bill, that’s the energy charge plus TXU’s $9.95 base charge.
Your utility (in Dallas-Fort Worth, that’s Oncor) owns the poles, wires and meter. It delivers the power and fixes outages. It bills delivery charges that get passed straight through to you. Those delivery charges are the same no matter which provider you pick, and they don’t go away in a "50% off" month.
So when TXU says "50% off," it means 50% off the energy charge only. At 1,000 kWh in the Oncor area, about $75 of your bill (the $9.95 base charge plus about $65 in Oncor delivery) never gets discounted, in any month. (Figures derived from TXU’s Electricity Facts Label, pricing dated Aug 1, 2026.)
Think of it like buying a $20 shirt online. A "half-off" coupon that only works on the shirt doesn’t touch the shipping or the tax.
How Does the TXU Ultimate Season Pass Compare to a Simple Plan?
At 1,000 kWh a month (Oncor area, Aug 1, 2026 pricing):
- Typical simple plan: about $131 every month.
- Season Pass, 50% off months (Jan, Feb, Jul, Aug): about $154, or $23 more.
- Season Pass, 25% off months (Mar, Jun, Sep, Dec): about $193, or $62 more.
- Season Pass, no-discount months (Apr, May, Oct, Nov): about $233, or $102 more.
- Over 12 months: about $2,316 vs. $1,572, or $744 more.
We took the Season Pass’s own facts label (pricing dated Aug 1, 2026) and figured a monthly bill at 1,000 kWh, before taxes. Then we compared it to a typical simple, fixed 12-month plan in the same area. Here’s what it looks like:
TXU Ultimate Season Pass: no-discount month (Apr, May, Oct, Nov)
about $233/mo
@ 1,000 kWh (Aug 1, 2026 pricing)
Typical Simple Plan (fixed, 12-month)
about $131/mo
@ 1,000 kWh (Power to Choose, Oct 27, 2026)
Across the year at a steady 1,000 kWh (Aug 1, 2026 EFL pricing vs. a typical simple plan at about $131):
• 50%-off month (Jan, Feb, Jul, Aug): about $154, which is +$23
• 25%-off month (Mar, Jun, Sep, Dec): about $193, which is +$62
• No-discount month (Apr, May, Oct, Nov): about $233, which is +$102
Over a year at a steady 1,000 kWh: about $2,316 on Season Pass vs. about $1,572 on the typical simple plan. That’s roughly $744 more.
Even TXU’s own published average for this plan at 1,000 kWh works out to about $186 a month, which is about $55 more than the typical simple plan.
We used the Oncor (Dallas-Fort Worth) area for these examples. Other utilities’ delivery charges differ, but the idea’s the same. We’re not endorsing any one provider or plan. The "typical simple plan" is the middle-priced fixed, 12-month, no-gimmick plan on the state’s Power to Choose site on October 27, 2026.

Cost Difference Between Plans
Cost difference in a no-discount month (Aug 1, 2026 pricing):
@ 500 kWh = +$55 for the TXU plan
@ 1,000 kWh = +$102 for the TXU plan
@ 2,000 kWh = +$193 for the TXU plan
Each month. Even in a 50%-off month, TXU still runs +$16, +$23 and +$35 at those usage levels (Aug 1, 2026 pricing).
Do TXU’s Discounts Offset the High Costs?
Eight months a year get a discount. Sounds good, until you look at what’s being discounted.
• 50% off the energy charge: Jan, Feb, July, Aug
• 25% off the energy charge: March, June, Sept, Dec
• Nothing: April, May, Oct, Nov
The discount only comes off TXU’s energy charge. The base charge and Oncor’s delivery charges bill in full every month (see "Utility vs. provider" above). And TXU’s energy charge starts out high. Even cut in half, it barely gets close to what a simple plan charges, and it never gets under it once you add the $9.95 base charge (Aug 1, 2026 EFL pricing).
What about electric heat? TXU pitches this plan as "great for electric heat homes." The winter break is 50% in January and February, but only 25% in December and none in November. In our math, more usage just makes the gap bigger: a no-discount month at 2,000 kWh runs about $193 more than a simple plan (Aug 1, 2026 EFL pricing).
Typical Texas Household Electricity Usage
Check out the chart below for a typical Texas household’s monthly electricity usage over one year. Usage varies seasonally, but monthly patterns stay steady year over year.
The sample above is for a house with a gas heater, as seen with low electricity usage in the winter months. If you have an electric heater, your usage will be higher in winter than what’s in the chart. But this is irrelevant when it comes to exposing the high cost of TXU’s Ultimate Season Pass Plan.
Cost of TXU's Ultimate Season Pass vs. Simple Plan
Using the steady 1,000 kWh example above (Aug 1, 2026 EFL pricing): about $23 extra in the half-off months, $62 extra in the 25%-off months, and $102 extra in the no-discount months. Use more power and the gap gets bigger.
Our Review: Is TXU’s Ultimate Season Pass Worth It?
After running TXU’s own numbers (Electricity Facts Label pricing dated Aug 1, 2026), the Ultimate Season Pass is one of the worst deals we’ve seen.
With most gimmick plans, somebody can come out ahead. Night owls can do OK on a free-nights plan, and steady users can sometimes win with a bill credit. This one’s different. In our math there wasn’t a single month, at 500, 1,000 or 2,000 kWh, where the Season Pass beat a typical simple plan. Not even the half-off months.
And that $450? TXU’s fine print says it comes from "an average of self-reported savings during discounted months from a 2024 survey of satisfied customers on Season Pass." That’s a survey of happy customers, not a price comparison.
Our advice: skip it. A plain, fixed-rate plan with no base charge will almost always cost you less. If you’re already on Season Pass, you can switch without the $150 fee in the last 14 days of your contract. If you’re a new residential customer, you get TXU’s 60-day guarantee.

TXU Ultimate Season Pass FAQ
Is the TXU Season Pass worth it?
Not in our math. Using TXU’s facts label for the Dallas-Fort Worth (Oncor) area, priced August 1, 2026, the plan cost more than a typical simple, fixed plan every month at 500, 1,000 and 2,000 kWh. That held even in the 50%-off months. At a steady 1,000 kWh, it worked out to roughly $744 more over a year.
Which months are free?
None. The Ultimate Season Pass gives 50% off TXU’s energy charge in January, February, July and August, and 25% off in March, June, September and December. April, May, October and November get no discount. The $9.95 base charge and your utility’s delivery charges are never discounted. (EFL pricing dated Aug 1, 2026.)
Is there a cancellation fee?
Yes: $150 if you leave before the 12 months are up. You can leave without the fee in the last 14 days of your contract, if you move and give TXU proof, or within 14 days after TXU notifies you of a change to your terms. New residential customers can also switch for free within 60 days under TXU’s satisfaction guarantee.
Who should skip it?
Pretty much anyone who wants a lower bill. That especially means homes with high spring and fall usage, since April, May, October and November get no discount, and anyone who’d rather not track which months are discounted. A simple fixed-rate plan is easier to figure out, and in our math it was cheaper every month.
Does the Season Pass really save $450 a year?
TXU’s $450 comes from “an average of self-reported savings during discounted months from a 2024 survey of satisfied customers on Season Pass.” That’s TXU’s survey, not a price comparison.
