The Short Answer
If you have rooftop solar, pick Chariot. Their buyback rates beat TXU by 20-30%—that’s real money every month. Everything else Chariot offers, TXU does better or cheaper.
TXU is a marketing machine that happens to sell electricity. Chariot is a solar company that happens to sell electricity. Pick based on what you actually need.
Overview
This comparison only matters if you have solar panels or care deeply about genuine solar infrastructure investment. Otherwise, TXU wins by default—and that’s not a compliment.
TXU Energy has been selling electricity to Texans for 24 years. Vistra Corp (NYSE: VST) owns them. They’re not going anywhere, but you’re paying 15-25% more than budget providers for the privilege of a familiar name.
Chariot Energy built their entire company around solar since 2014. They source from actual solar infrastructure, not paper certificates. Ten years of solar-focused operation while TXU was still treating green energy as a marketing checkbox.
Same grid. Same wires. The difference is what your money funds.
The Solar Buyback Question
This is the only reason to seriously consider Chariot over TXU.
TXU’s solar buyback: Minimum compliance rates. Regulatory checkbox. You’ll get paid for excess generation, but TXU designed this program to exist, not to benefit you.
Chariot’s solar buyback: 20-30% higher rates than TXU [ComparePower rate analysis]. Designed from the ground up for solar homeowners. Faster crediting, less paperwork, actual financial benefit.
If you’ve invested $20,000+ in rooftop solar, Chariot’s buyback rates could return an extra $200-$500 annually compared to TXU. Over a 10-year panel lifespan, that’s $2,000-$5,000 in your pocket instead of TXU’s.
No solar panels? This comparison doesn’t apply to you.
Plan Variety
TXU wins by knockout.
TXU offers:
- Fixed-rate plans (12-36 months)
- Variable-rate plans
- Indexed plans tied to wholesale
- Time-of-use plans
- Free nights and free weekends
- Green energy options
Chariot offers:
- Fixed-rate solar plans
- Solar buyback
- Community solar
If you want free nights, TXU has them. If you want time-of-use pricing, TXU has it. If you want indexed plans, TXU has it. Chariot does one thing well—solar—and that’s it.
Customer Service
TXU wins again.
TXU’s support: 24/7 phone lines with 5-8 minute average wait times. Best-in-class among major Texas providers. You’re paying for this in your rates, but it exists when you need it.
Chariot’s support: Smaller company, smaller operation. Business hours support. They know solar inside and out, but don’t expect 2am assistance.
Green Energy: Who’s More Legitimate?
Chariot wins on authenticity.
TXU’s “green” plans: Conventional electricity with Renewable Energy Certificates (RECs) that “offset” your usage. Paper credits. Accounting tricks. Your money doesn’t fund new solar infrastructure.
Chariot’s approach: Sources from actual Texas solar farms. Your bill supports real solar infrastructure investment. They’ve been doing this since before TXU’s marketing team discovered green energy sells.
If you want genuine environmental impact, Chariot delivers what TXU’s marketing promises.
The Verdict
Choose TXU if:
- You don’t have solar panels
- You want free nights, time-of-use, or specialty plans
- 24/7 phone support matters to you
- You value brand stability over solar authenticity
Choose Chariot if:
- You have rooftop solar (20-30% better buyback rates)
- Community solar programs interest you
- You want genuine solar investment, not green certificates
- You’re willing to trade plan variety for solar expertise
The real answer: If you have solar panels, run the numbers on Chariot’s buyback rates. If you don’t have solar panels, TXU or a budget provider like Frontier makes more sense than Chariot’s solar-focused model.
