Bottom Line: This is no longer a real comparison. Flagship Power closed in May 2024. TXU Energy remains the most recognized electricity brand in Texas — 24/7 support, every plan type, and Vistra Corp’s Fortune 500 stability.
What Happened to Flagship Power?
Flagship Power was an independent budget provider that operated from 2019 to May 2024 under Utility Rescue Holdings. They posted some of the lowest rates in Texas but had no corporate backing.
In May 2024, Flagship ceased operations. Customers were transferred to Atlantex Power and AE Texas.
Flagship’s closure is a textbook example of what happens when small independent providers cannot sustain operations. TXU Energy, backed by Vistra Corp, has operated continuously for 24 years through every market disruption.
Why TXU Energy Is Still Here
TXU Energy is the most established residential electricity brand in Texas, backed by Vistra Corp — one of the largest power companies in the country. Vistra also owns 4Change Energy, Ambit Energy, and several other Texas brands.
What TXU Energy offers:
- Every plan type: fixed, variable, time-of-use, free nights, free weekends, green, solar buyback
- 24/7 customer support — one of the few providers that offers round-the-clock service
- 24 years of continuous Texas operations
- Vistra Corp backing — Fortune 500 financial stability
- Strong mobile app and online account management
- Service across all major Texas TDU areas
TXU charges premium rates — typically the highest among major providers. You pay for brand recognition, 24/7 support, and the widest plan selection in Texas.
If You Were a Flagship Customer
Your account was likely transferred to Atlantex Power or AE Texas. Check your current rate and plan terms.
If you chose Flagship for rock-bottom pricing, TXU will cost significantly more. For Vistra-backed budget rates, check 4Change Energy — same corporate parent, much lower prices. For mid-tier options, Gexa Energy or Frontier Utilities offer competitive rates with corporate backing.
The Verdict
Choose TXU Energy if you want the most established brand in Texas electricity with 24/7 support, every plan type available, and Vistra Corp’s Fortune 500 financial backing.
