TXU Energy Review 2026

TXU Energy is the largest Retail Electric Provider in Texas, serving more than 1.8 million customers statewide. The company's lineage traces to 1882, when Texas Power & Light was founded — making TXU one of the oldest electricity enterprises in the state. Through a century of mergers, regulatory changes, and the historic 2007 leveraged buyout by KKR and TPG (then the largest LBO in history), TXU Energy emerged as the dominant retail brand after Texas deregulation separated generation, transmission, and retail in the early 2000s. Today TXU Energy is a subsidiary of Vistra Corp.

TXU Energy serves all major ERCOT TDU territories including Oncor, CenterPoint, AEP Texas, and TNMP. The company offers an extensive product lineup: standard fixed-rate plans, free nights plans (electricity free from 9 PM to 6 AM), free weekends, solar buyback plans, and TXU Energy Rewards, a loyalty points program. Rates range from approximately 10 to 16 cents per kWh depending on term and features.

Pros: Largest network of local service agents, robust mobile app, extensive plan variety, strong customer service infrastructure, TXU Energy Aid charity program.

Cons: Rates are often above the market median; the brand premium means cost-focused shoppers can find cheaper options among smaller REPs.

Unique Differentiator: TXU's Free Nights plan is one of the most heavily marketed time-of-use products in Texas — households that shift dishwasher, laundry, and EV charging to overnight hours report meaningful bill reductions compared to flat-rate plans.
