Overview
Does it even matter?
Here’s what TXU and Gexa won’t tell you: the electricity is identical. Same wires. Same grid. Same electrons flowing through your walls. When you flip the switch, Oncor delivers the power—not TXU, not Gexa. They’re just billing companies with different logos.
So what are you actually choosing between? Marketing budgets.
TXU spends millions on Cowboys games, billboards, and that jingle stuck in your head. Gexa’s parent company (NextEra, worth $150 billion) could do the same—they just don’t bother. Guess which one charges you more.
Gexa wins this comparison for most people. You’re not paying for better electricity. You’re paying for TXU’s ad agency.
Here’s What They Don’t Tell You
Both companies buy power from the same wholesale market. Both use Oncor, CenterPoint, or AEP to deliver it to your home. Both charge you roughly the same pass-through costs for transmission and distribution.
The only difference is profit margin and overhead. TXU’s overhead includes Super Bowl commercials. Yours doesn’t have to.
The Real Price Difference
On a 12-month fixed plan at 1,000 kWh, Gexa typically runs $15-25/month cheaper than TXU. That’s $180-300/year for the same electrons.
TXU charges a brand premium. You’re funding TV commercials, stadium sponsorships, and a 24/7 call center you’ll use maybe once.
Gexa skips the marketing circus and competes on price. The electricity doesn’t care what logo is on your bill.
Plan Options
TXU has everything: fixed, variable, time-of-use, free nights, free weekends, prepaid, indexed. Want a 36-month contract with free electricity from 9pm-6am? TXU built that.
Gexa keeps it simple: fixed-rate, variable, green. Three plan types, done. If you run AC all night and want free nights pricing, Gexa can’t help you.
Customer Service
TXU has 24/7 phone support. Call at 2am, someone answers.
Gexa closes at 7pm CT. If your power goes out at midnight and you want to yell at someone, you’re waiting until morning. (Your TDU handles outages anyway—but some people want that 3am phone option.)
The Verdict
Gexa wins for most Texans. Same electricity, lower price, Fortune 200 backing. TXU is only worth it if you need specific features.
Choose TXU if:
- You need free nights/weekends or indexed pricing plans
- 24/7 phone support is non-negotiable
- You want 15+ plan options to compare
- You’ll pay $200+/year extra for those features
Choose Gexa if:
- You want to save money on a basic fixed-rate plan
- Business hours support is fine
- You don’t need specialty plan structures
- You’d rather keep $200/year than fund TV commercials
