Company Overview

TXU charges 15-25% more than competitors for identical electricity [ComparePower rate analysis, 2.5M+ enrollments]. Same grid. Same wires. Same electrons hitting your meter. You’re paying for the brand your parents had—and the TV commercials that keep that name familiar.

Vistra Corp [NYSE: VST] owns TXU. They’re worth over $25 billion and aren’t going anywhere. That stability costs you roughly $200-$400 per year compared to mid-tier providers like Gexa or Frontier [ComparePower rate analysis]. We’ve tracked this across millions of signups—TXU almost never wins on price, but they know most Texans won’t shop around.

TXU sells you electricity. Oncor, CenterPoint, or your local utility delivers it. When your power goes out, TXU can’t help you—that’s the utility’s job.

Where TXU Operates

TXU serves everywhere that matters in deregulated Texas: Dallas–Fort Worth, Houston, Arlington, Plano, Irving, Corpus Christi—anywhere Oncor, CenterPoint, AEP, or TNMP runs the lines.

Austin and San Antonio? Municipal utilities run those cities. TXU can’t sell there, and neither can anyone else on this site.

Plan Types Offered

Fixed-Rate Plans Lock in a rate for the contract term. Most popular option. Terms range from 12 to 36 months.

Variable-Rate Plans Rate changes monthly based on market conditions. No long-term contract, but no price protection either.

Indexed Plans Rate tied to a formula (often wholesale price plus an adder). Can be cheaper in mild months, more expensive in extreme weather.

Time-of-Use Plans Different rates for different times of day. Can save money if you shift usage to off-peak hours.

Free Nights / Free Weekends Electricity is free during specific hours, but the base rate is higher. Works well for some usage patterns, badly for others.

Deposit Requirements

TXU runs a credit check on everyone. Score above 650? No deposit. Below that? You’re paying $200-$400 upfront.

Two ways around it: bring a letter of credit from your previous provider showing 12 months of on-time payments, or enroll in AutoPay on certain plans. TXU doesn’t offer prepaid, so if your credit is rough, you’re either paying the deposit or looking elsewhere.

Customer Service: The Real Story

TXU runs the best customer service operation among the big Texas providers. That’s not a high bar, but they clear it.

Worth knowing:

• Phone wait times average 5-8 minutes [Service testing, Q4 2025]. Budget providers regularly hit 30+ minutes.
• The app works: real-time usage data, bill pay, outage notifications
• Live chat connects to humans who can fix problems, not just read scripts

The catch:

• TXU’s renewal team is relentless. Starting 60 days before your contract ends, your inbox fills with “special offers” that aren’t special. They’ll call too.
• Ask them to match a competitor’s rate and they’ll politely decline. We’ve seen this pattern thousands of times—TXU doesn’t negotiate.
• That 24/7 support? You’re funding it. TXU’s rates bake in this overhead.

The bottom line: TXU’s customer service justifies maybe $5-$10/month of their premium. The other $15-$20? That’s brand tax.
