TXU Energy Review 2026: Rates, Plans, and Is It Worth It in Texas?
TXU Energy is the largest retail electricity provider in Texas by market share, serving more than 1.7 million customers across the ERCOT deregulated market. It’s also one of the oldest — descended from Texas Utilities, which served the state as a regulated monopoly for decades before deregulation. That legacy comes with name recognition and a wide plan selection, but also with rates that often run higher than leaner competitors targeting the same service territory.
This review covers TXU’s current plan offerings, pricing, contract terms, customer satisfaction data, and who it’s actually a good fit for in 2026.

TXU Energy Plan Options (2026)
Fixed-Rate Plans
TXU’s bread-and-butter offering is a 12-month fixed-rate contract. In 2026, rates for a 1,000 kWh/month household in Oncor territory (Dallas-Fort Worth) typically run in the 12–16 cents per kWh range all-in, which is competitive during periods of moderate wholesale prices but can look expensive when spot competitors offer 10–12 cents during low-demand months. The advantage of a TXU fixed-rate plan is rate stability — you know exactly what you’re paying per kWh for the length of the contract regardless of ERCOT market swings.
Free Nights and Weekends
TXU popularized the free nights and weekends concept in Texas. These plans offer “free” electricity during off-peak hours (typically 9 PM–6 AM nights; all day Saturday–Sunday) in exchange for higher daytime rates. They work well for households that can shift high-consumption activities — dishwasher, laundry, EV charging — to off-peak windows. Heavy daytime workers-from-home typically pay more on these plans than on a straightforward fixed-rate plan. Read the EFL (Electricity Facts Label) carefully before signing up.
Prepaid Plans
TXU’s prepaid option (TXU Energy Prepaid) has no credit check, no deposit, and no contract. You load funds to your account and pay as you go. Daily usage notifications help you track spend. The per-kWh rate is typically higher than standard fixed-rate plans, but the flexibility and no-deposit feature make it the right choice for customers with credit challenges or those who only need short-term service.
Variable-Rate and Indexed Plans
TXU offers variable-rate month-to-month plans that track wholesale market prices. These can save money when ERCOT prices are low but expose customers to dramatic spikes during extreme weather events. Given Texas’s history with Winter Storm Uri (February 2021), most residential customers are better served by fixed-rate plans unless they have a specific reason to want market exposure.
TXU Energy Pricing: How It Compares
TXU consistently prices at or above the Texas market average for fixed-rate plans. The name recognition premium is real — TXU invests heavily in customer service infrastructure, a physical retail presence, and a robust mobile app, which costs money that flows through to rates. In head-to-head comparisons for the same service territory and contract length, you can typically find 10–20% lower rates from providers like Gexa Energy, Pulse Power, Frontier Utilities, or Constellation Energy.
The best way to know your actual TXU rate vs. alternatives is to run your ZIP code through a rate comparison tool with your actual monthly usage. The EFL (Electricity Facts Label) for each TXU plan breaks out the exact per-kWh cost at 500, 1,000, and 2,000 kWh usage levels — always compare at your actual usage tier, not the headline rate.

Customer Service and Satisfaction
TXU Energy’s Trustpilot score of 2.9/5 is below the industry average for Texas retail electricity providers, which cluster around 3.2–3.8. The most common complaints in negative reviews involve billing disputes, difficulty canceling auto-pay, and unexpected charges at contract end when customers roll to a variable month-to-month rate after their fixed-rate contract expires. The last point is a known issue across the Texas retail electricity market — providers are required by PUCT rules to notify customers 30 days before contract expiration, but customers who miss the notification can find themselves on significantly higher variable rates for months.
On the positive side, TXU’s customer service hours are among the longest in the market (24/7 phone support), and the MyTXU mobile app has solid reviews on both iOS and Android for usage tracking, payment, and outage reporting. For customers who prioritize customer service infrastructure over lowest possible rate, TXU’s investment in support channels shows.
Who Should Consider TXU Energy?
TXU Energy is a reasonable choice for customers who prioritize brand familiarity, a robust customer service network, and plan variety over finding the absolute lowest rate. The free nights/weekends plans are genuinely useful for households with flexible usage schedules. The prepaid option is one of the better no-deposit plans in the Texas market.
If your primary goal is the lowest possible electricity rate, you will almost certainly find better options by comparing TXU against the full Texas market. Texas has more than 100 retail electricity providers competing for your business — use that competition.
