The verdict
TXU fits Texans who want a trusted, full-service incumbent with a polished app and specialty plans — especially solar homeowners (its buyback suite is strong) and night-heavy households (free nights) — and who'll pay a premium for that breadth and brand. Pure price-shoppers will almost always find a cheaper rate elsewhere, which is exactly the gap a flat-rate provider like Base targets.
The company
Who is TXU Energy?
TXU Energy is the largest and best-known retail electricity provider in Texas, serving roughly 1.7 million customers statewide. It dates to deregulation in 2002 and, after a turbulent decade — a 2007 private-equity buyout and its parent's 2014 bankruptcy — emerged under Vistra Corp, which rebranded the parent in 2016. TXU's parent is Vistra, not NRG (a frequent mix-up among the big Texas brands).
TXU's strength is breadth. It offers the widest plan menu in the state — fixed-rate, bill-credit, free-nights and time-of-use, and an especially deep solar buyback suite — plus a well-regarded mobile app. The trade-off is price: its mass-market fixed plans are consistently positioned at a premium, which is the recurring theme in both its reviews and its complaint data.
Founded
2002
Headquarters
Irving, TX
Parent company
Vistra Corp (NYSE: VST)
Ownership: TXU Energy was taken private in 2007 (by KKR, TPG, and Goldman Sachs via Energy Future Holdings), survived that company's 2014 bankruptcy, and emerged under a reorganized parent that rebranded to Vistra Energy in 2016. Its parent is Vistra Corp — not NRG.
Scale & coverage: TXU Energy the largest residential REP in Texas, with roughly 1.7 million customers, across statewide deregulated Texas — Oncor, CenterPoint, AEP Texas, and TNMP.
Plans & pricing
TXU Energy plans and rates
TXU's advertised rates are as advertised in late May 2026 and varies by utility zone and usage — treat these as representative, not a quote, and check the live Electricity Facts Label on Power to Choose before you sign up.
Free Nights & Solar Days (time-of-use)
Free electricity overnight (8pm–4:59am) with higher daytime rates — built for night-heavy and solar homes.
Solar buyback suite
Solar Club / Buyback Match plans with strong export credits — among the best for solar homeowners.
Fixed-rate
Simple Secure / Smart Edge fixed plans, generally priced at a premium to the market.
Bill-credit
Usage-threshold credit plans where the advertised rate depends on your usage band.
Positioning
Premium-priced
Third-party reviewers repeatedly flag TXU's mass-market rates as running well above the going market rate.
Solar buyback ETF
$395 (Solar Buyback Match 36)
Waived on a verified move; buyback credits run roughly $0.10–$0.12/kWh against purchase rates ~$0.19–$0.24/kWh on those plans.
Free-nights window
Free energy 8pm–4:59am
Daytime rates (~18–22¢/kWh) are set higher to fund the free window.
The fine print
TXU Energy fees and the fine print
TXU's bill is its energy charge plus the pass-through TDU delivery charges your utility sets. Its specialty plans (free nights, solar buyback) are genuinely strong for the right home, but the mass-market fixed plans carry a premium — so the brand and app come at a cost. Check the early-termination fee on your specific plan's EFL; the solar plans run around $395.
Every Texas provider passes the same regulated TDU delivery charges through to you, so delivery isn't where providers actually compete — the energy charge and plan structure are. Always pull the Electricity Facts Label and compare the all-in cost at your real usage.
What customers say
TXU Energy customer reviews
TXU is the clearest case in this whole set for reading review scores carefully. Its unsolicited Texas Electricity Ratings score is the lowest here (1.4/5), yet its solicited Trustpilot and Google ratings are among the highest (~4.7), and the PUCT's own complaint scorecard — which adjusts for customer count — rates TXU well because its complaint rate is low even though the raw number is large. The honest read: a lot of people are quietly satisfied (especially with the app and named reps), while price-driven frustration dominates the venues people seek out to vent.

Where it falls short
Common TXU Energy complaints
- High, premium pricing — the dominant theme, with rates often cited well above the market average.
- Unexpected bill increases and tiered-plan threshold surprises.
- Customer-service friction — long hold times and offshore call-center complaints.
TXU's raw PUC complaint count is large (on the order of 449 in a recent trailing year), but that's mostly a function of its ~1.7 million-customer base — on the PUCT's rate-adjusted complaint scorecard, TXU actually scores well. Present both: the raw number looks alarming, the per-customer rate is low. Pricing, not service failure, is the real story.
In fairness
What TXU Energy is genuinely good at
- Brand recognition and longevity — Texas's most established REP, with the reliability and scale of a Vistra-backed incumbent.
- A well-regarded mobile app and online account management, plus a low rate-adjusted complaint score on the PUCT scorecard.
- The widest plan variety in the state — best-in-class solar buyback and free-nights options for the homes that fit them.
Side by side
TXU Energy vs. Base
TXU competes on breadth and brand; its specialty plans are strong, but its mass-market rates carry a premium. Base competes on the opposite: one flat energy rate (advertised at 8¢/kWh) at any usage, plus a flat monthly membership, with the TDU delivery passed through without markup and an optional whole-home battery as a separate product. If you don't need a specialty plan, the flat model strips out the premium and the timing math.
Flat & clear | TXU Energy | |
|---|---|---|
| Energy pricing | Flat 8¢/kWh at any usage Advertised energy charge | Varies by plan Often tiered, bill-credit, or time-of-use |
| Monthly charge | Flat $19–$29 membership | Energy charge + any plan fees |
| TDU delivery | Passed through, no markup | Passed through, no markup |
| Optional whole-home battery (separate product) | yes | no |
| Bottom line | Delivery charges are identical no matter who you pick — compare the all-in energy cost at your real usage on each EFL. | |
Base reports up to 42% savings versus TXU in its own bill comparisons (basepowercompany.com/compare) — its largest claimed gap on this list, consistent with TXU's premium positioning. That's Base's own published figure, not a third-party finding; confirm against both EFLs at your usage.
