The price tag on TXU’s Smart Deal is calculated at 1,000 kilowatt-hours. The plan’s $50 credit doesn’t switch on until 1,200.
Hold those two numbers next to each other. The rate you shop on comes from a month where the plan’s signature discount never fires — and that’s not sloppiness, it’s the design.
TXU Energy Smart Deal 12 is a nearly-20¢ rate wearing a $50 discount it only pays when your usage clears a bar most Texas homes miss for half the year. We pulled the plan’s official pricing fact sheets — dated August 6, 2026 — and ran the math. Here’s how the trick works, and who it actually works for.
Three moving parts, one tripwire
Strip the name off and the Smart Deal is three moving parts, straight from the pricing fact sheet (the EFL):
- A $9.95 monthly base charge — before you use a single unit.
- A tiered energy charge. In Houston: 12.3¢ per kilowatt-hour up to 1,200 kWh, 6.2¢ from 1,201 to 2,000, and 12.9¢ past 2,000. Your utility’s delivery charges ride on top.
- A $50 bill credit — in any billing cycle where you use 1,200 kWh or more. TXU raised it from $30 to $50 for new sign-ups starting July 1, 2025, per Choose Texas Power.
It comes in 12-, 24-, and 36-month terms. No free nights, no gadgets, no fake check in the mail — TXU saves that one for Free Pass. The Smart Deal’s hook is simpler and older: a discount you have to earn by using enough electricity.
The word doing the heavy lifting in that sentence is “enough.”
What the fact sheet admits
Every Texas plan has to print its average price at three usage levels. Here’s the Smart Deal 12, from the EFLs TXU generated on August 6, 2026:
| Average monthly use | 500 kWh | 1,000 kWh | 2,000 kWh |
|---|---|---|---|
| Dallas–Fort Worth (Oncor) | 20.9¢ | 19.5¢ | 13.9¢ |
| Houston (CenterPoint) | 21.3¢ | 19.8¢ | 14.1¢ |
Average price per kilowatt-hour, delivery charges included, from the official Smart Deal 12 EFLs for Oncor and CenterPoint territory, both dated August 6, 2026. Rates checked August 6, 2026. The 24-month version listed about a half-cent higher on Choose Texas Power the same day.
For scale: plain no-gimmick 12-month plans on Power to Choose the same day ran about 10.5–11¢ at 1,000 kWh in Houston. Even TXU’s own plainest plan, Simple Rate 12, listed at 16.2¢ per Texas Electricity Ratings. At the usage most homes actually match, most months, the Smart Deal costs nearly double the cheap end of the same wires.
Now read the table’s shape: 21.3, then 19.8, then 14.1. A plain plan’s three numbers sit within a penny of each other. A seven-cent slide is the fingerprint of a plan with a number you have to hit.
The cliff at 1,200 kWh
Bill-credit plans don’t taper — they cliff. At 1,200 kWh the credit is $50. At 1,199 it’s zero — not $49.96, not most of it, nothing.
Run three months through the Houston EFL’s own pricing. (Our arithmetic: we back-calculated CenterPoint’s delivery charges — about $5 a month plus 6¢ per unit — from the EFL’s average-price columns, and they reproduce all three columns to the penny. The plain-plan column is a labeled illustration at a flat 11¢, the going rate for no-gimmick plans that day.)
| Your month | Smart Deal bill | Plain 11¢ plan | The Smart Deal premium |
|---|---|---|---|
| 1,180 kWh — miss the line by 20 | ~$231 (19.6¢/unit) | ~$130 | +$101 |
| 1,220 kWh — clear it | ~$187 (15.3¢/unit) | ~$134 | +$53 |
| 2,000 kWh — the plan’s best case | ~$282 (14.1¢/unit) | ~$220 | +$62 |
Two things in that table should stop you.
The plan never wins. At August 2026 prices there is no monthly usage — none — at which the Smart Deal beats a plain 11¢ fixed-rate plan on the same wires. Its best possible month, exactly 2,000 kWh at an effective 14.1¢, still loses by about $62. The credit isn’t a path to a cheap bill. It’s a discount on an expensive one.
The plan punishes saving power. Seal the windows, nudge the thermostat, and if that drops you from 1,220 to 1,180 kWh, your bill goes up about $44. Run the mirror image and it’s stranger still: near the line, 40 kWh of deliberately wasted power saves you $44. Any plan where waste is the rational move was not built around your interests.
Even against TXU’s own Simple Rate 12, the Smart Deal only pulls ahead in months you clear the line — and hands the savings back, with interest, in the months you miss.
The 6¢ band that dresses up the fact sheet
Look again at those Houston tiers: 12.3¢, then 6.2¢ from 1,201 to 2,000, then 12.9¢. A half-price band, exactly 800 kilowatt-hours wide, that snaps back to full price the moment you pass 2,000. That’s not generosity. That’s engineering.
The disclosure rules make every company print averages at 500, 1,000, and 2,000 kWh — and the cheap band plus the $50 credit are both aimed squarely at the last column. They make the 2,000-kWh figure read 14.1¢, the one number on the sheet that looks like a bargain. The 1,000-kWh column reads 19.8¢, which is why the plan needs the “$50 off” pitch to move at all.
And the money has to come from somewhere. TXU charges roughly 15–25% more than budget companies across its lineup — that’s the company’s model — so the credit hands you back some of your own overpayment, some of the time.
This is the standard anatomy of the bill-credit trap, and TXU runs it twice. The Smart Deal’s sibling, Smart Edge, pays the same $50 at an 800-kWh line, and its August 2026 Houston fact sheet carries the same fingerprint: 20.6¢ at 500 kWh, 14.1¢ at 1,000, 18.8¢ at 2,000. Cheap at the column the pitch points at. Expensive where you actually live.
Four clauses that cost you later
The 60-day guarantee expires before you’ve seen the plan’s bad side. TXU’s satisfaction guarantee lets you swap plans free in your first 60 days, and that’s genuinely better than most companies offer. But your first bill lands around day 30 — one bill, in one season. Sign up in July and your first two bills will both clear 1,200 kWh easily. The credit posts, the plan looks brilliant, the window closes. The October bill that misses the line by 80 kWh arrives long after your free exit did.
Leaving costs $150 — or a lot more. The 12-month term carries a $150 early cancellation fee, per the EFL. Choose Texas Power lists the Smart Deal family’s fees at up to $395 on the longest term — and the Smart Deal 36 locks today’s pricing, and today’s tripwire, through the summer of 2029. Don’t sign three years of anything built around a usage number you haven’t checked against your own history.
The $50 is a new-customer number. TXU raised the credit for new enrollments in July 2025. What the renewal offer looks like when your term ends is a different conversation — renewal quotes tend to run higher than what new customers see on the open market. Whatever TXU quotes you at renewal, counter-shop it before you nod.
Delivery fees ride on top. Like every plan in Texas, your utility’s delivery charges apply to all your usage, credit month or not. The $50 shaves the bill; it doesn’t touch the wires-and-poles line items underneath it.
Two more footnotes from the fact sheet: the plan is 3% renewable (the statewide average is 37%), and TXU runs a soft credit check — no deposit if yours is clean.
Is the Smart Deal ever a good deal?
Honestly: for two kinds of homes, it’s defensible. Never the winner — defensible.
The big steady house. 2,500+ square feet, electric heat, pool pump, family of five — the home that lands between 1,200 and 2,000 kWh eleven or twelve months a year. Hit that band every month and the effective price runs 14–15.5¢ at August 2026 EFL numbers, which is no longer embarrassing. Still ten-plus dollars a month behind a cheap plain plan at the same usage — but with TXU’s genuinely good 24/7 phone support and the 60-day swap window attached.
The committed TXU household. If you’ve already decided you want the brand — the app, the humans who answer at 2am — and you clear 1,200 kWh at least ten months a year, the Smart Deal beats TXU’s own Simple Rate 12 above the line. Inside TXU’s lineup, it’s the better offer for a heavy user. Against the open market, it isn’t.
Most homes aren’t either of these. Pull a year of bills — your online account has them — and count how many months you actually crossed 1,200 kWh. If the answer is eight or nine, the three or four full-freight months near 20¢ will quietly eat everything the credit gave you.
And even the every-month household should put the Smart Deal’s average price at their usage level next to a plain fixed-rate plan from Gexa or Frontier. The plain plan usually wins without asking you to hit a number.
That’s the tell with every plan built around a conditional reward: if the deal were good at your usage, it wouldn’t need a condition.
If the three numbers don’t sit level, walk
This works on any Texas plan, not just this one. Open the pricing fact sheet and find the three-column average price table — 500, 1,000, 2,000 kWh. Then look at the spread:
- A plain plan sits level. The cheapest no-gimmick Houston plans in August 2026 read something like 11.0¢ / 10.5¢ / 10.3¢. Boring. Boring is what you want.
- A cliff plan slides. The Smart Deal reads 21.3 / 19.8 / 14.1 — seven cents top to bottom. Smart Edge reads 20.6 / 14.1 / 18.8 — a valley with one good column.
If the three numbers don’t sit level, somewhere in the fine print is a number you have to hit. Find it before you sign, and ask what happens in the months you miss.
What to do instead
Ten minutes, start to finish:
- Get your last 12 months of usage. It’s on your bills or in your TXU or utility online account. Count the months over 1,200 kWh — that single number decides whether this plan was ever for you.
- Read the pricing fact sheet at YOUR usage level, not 1,000 kWh. The average-price table is the only honest sentence in any plan’s marketing. If your typical month is 900 kWh, this plan has no credit in it for you — just a base charge, a 12.3¢ meter, and delivery fees on top.
- Compare total yearly cost across companies on ComparePower — including TXU’s own plain fixed plans, which often beat TXU’s headline plans at the same usage.
A plan with no credit, no threshold, and no sweet spot usually costs less than one with all three. The $50 was never a gift. It was bait for a rate you’d never accept without it.
