Overview
TXU and Cirro are flagship brands from competing corporate giants.
TXU Energy is Vistra’s premium Texas brand. 24/7 support, free nights plans, time-of-use options, green energy as an add-on. They charge more because they deliver more—or at least, more options.
Cirro Energy is NRG’s green-included mid-tier brand. Every plan comes with renewable energy at no extra charge. Simpler plan menu, cheaper than TXU, but notably higher PUCT complaint rates.
Both companies will exist next year. Neither is a financial risk. The question is whether you want TXU’s service premium or Cirro’s green-included value.
The Short Answer
Want the best customer service? TXU has 24/7 support and lower complaint rates.
Want green energy without paying Green Mountain’s premium? Cirro includes it free in every plan.
Want specialty plans? TXU has free nights and time-of-use. Cirro doesn’t.
Want low-risk trial? Cirro’s 30-day satisfaction guarantee lets you leave penalty-free.
Understanding the Parent Companies
TXU Energy is owned by Vistra Corp (NYSE: VST), worth $25+ billion. Vistra also owns Dynegy and Luminant. TXU is their retail flagship.
Cirro Energy is owned by NRG Energy (NYSE: NRG), worth $70+ billion. NRG also owns Reliant, Green Mountain, Pennywise, and Discount Power. Cirro sits between Reliant (premium) and Pennywise (budget) in their lineup.
Both parents are Fortune 500 energy giants. Neither company presents stability concerns.
The Green Energy Difference
This is Cirro’s genuine advantage.
Cirro: Every plan includes 100% renewable energy at no premium. Wind and solar baked into the rate. You don’t select a “green” tier—it’s just there.
TXU: Green energy plans cost extra. Their standard plans use conventional power. If you want renewable, you pay for it.
The value: Green Mountain (NRG’s green-focused brand) charges 15-25% more for similar renewable coverage. Cirro delivers the same thing at mid-tier pricing. That’s meaningful if green energy matters to you.
The Complaint Rate Problem
Cirro’s above-average PUCT complaint rate is real and concerning.
Cirro runs notably higher than sibling brand Reliant on complaints [PUCT Complaint Database, Q4 2025]. Billing disputes, customer service responsiveness issues, problems that drag on for multiple calls.
TXU maintains lower complaint rates and invests heavily in resolution. Their customer service operation is among the best in Texas.
Same NRG infrastructure, but Cirro isn’t the priority brand. They inherited the backend without the customer service investment.
Plan Variety Comparison
TXU offers:
- Fixed-rate (12-36 months)
- Variable (month-to-month)
- Indexed (tied to wholesale prices)
- Time-of-use (different rates by hour)
- Free nights and free weekends
- Green energy (additional cost)
Cirro offers:
- Fixed-rate (12-36 months)
- Variable (month-to-month)
- Green energy (included free)
No free nights. No time-of-use. No indexed plans. If you need specialty plan structures, TXU delivers what Cirro can’t.
Customer Service Comparison
TXU:
- 24/7 phone support
- 5-8 minute average wait times
- Full-featured app
- Lower PUCT complaint rates
Cirro:
- Phone support closes at 10pm Central
- Above-average PUCT complaints
- Basic online account management
- 30-day satisfaction guarantee (cancel penalty-free)
The 30-day guarantee is Cirro’s hedge against their service issues. Try them risk-free; if you’re unhappy, leave without penalty. TXU locks you into contracts immediately.
Deposit Policies
Both run credit checks. Both require deposits if you fail.
TXU: Score above 650 typically avoids the deposit. Otherwise, $200-$400 upfront or a letter of credit.
Cirro: Score above 650 avoids the deposit. Otherwise, $150-$300 upfront or a letter of credit.
Neither offers prepaid.
The Verdict
TXU wins on service and plan variety. Cirro wins on green energy value. Both win on stability.
Choose TXU if:
- Customer service quality is your top priority
- You want free nights, time-of-use, or specialty plans

- The 30-day satisfaction guarantee reduces your risk
- Simple fixed-rate plans are all you need

The honest answer: If green energy matters but service quality also matters, this is a tough choice. Cirro delivers green included; TXU delivers better support. The 30-day guarantee lets you test Cirro’s service firsthand with minimal risk.
