Bottom Line: Chariot serves solar panel owners who want real buyback rates. Frontier serves everyone who wants to save money on the same electricity. If you don’t have solar, Frontier saves you hundreds annually.
The Short Answer
Do you have solar panels? Choose Chariot. Their buyback rates beat competitors by 20-30%, and that math changes everything.
No solar panels? Choose Frontier. You’ll save $200-$350/year compared to TXU and Reliant—and Chariot—on identical electricity from the same grid.
The solar question is the only question. Everything else is just details.
Company Backgrounds
Chariot Energy is an independent, Houston-based company that built everything around solar since 2014. Solar buyback, community solar, 100% solar plans. Ten years of solar-focused operation. If you don’t have panels, you’re paying for infrastructure you won’t use.
Frontier Utilities is owned by Centrica plc, a British energy giant worth more than TXU’s parent company. Fifteen years in Texas since 2008. No bankruptcy scares, no financial instability. They skip advertising and pass the savings to you—10-15% below the big brands.
The stability question: Frontier has Fortune 500 backing through Centrica. Chariot is independent with no corporate parent. For most customers, this won’t matter. For risk-averse customers, Frontier’s backing provides peace of mind.
Pricing Reality
Frontier wins on price. Consistently 10-15% below TXU and Reliant. That’s $200-$350/year on a typical Texas home. Same grid, same electrons, different price tag.
Chariot charges solar premiums. You’re paying for solar-first infrastructure, buyback programs, and community solar. Without solar panels, that premium is pure overhead—potentially $300-500/year more than Frontier.
The exception: If you have solar panels generating meaningful power, Chariot’s superior buyback rates can offset their higher base prices. We’ve seen solar owners come out ahead with Chariot despite the premium.
Solar Buyback: Chariot’s Only Advantage
Chariot’s buyback rates beat TXU, Reliant, and Frontier by 20-30%. If you’re generating 500+ kWh monthly in solar, those superior rates translate to real money back.
Frontier doesn’t offer solar buyback. At all. If you have solar panels, Frontier can’t buy your excess generation.
For solar owners: Chariot. The buyback rates justify the premium.
For everyone else: Frontier. You’re not getting anything from Chariot’s solar infrastructure except higher bills.
Green Energy Options
Both offer “green” plans. The difference is meaningful.
Chariot: Sources from actual solar farms. Community solar programs let you participate without installation costs. This is genuine investment in solar infrastructure.
Frontier: Offers 100% renewable plans through renewable energy certificates. Technically green—somewhere, renewable energy was generated equal to your usage. Practically, it’s a checkbox.
If green energy drives your decision: Chariot delivers authentic solar. Frontier delivers a certificate.
If green is secondary to price: Frontier’s certificate plans cost less than Chariot’s solar infrastructure.
Customer Service: Neither Wins
Both companies cut customer service to invest elsewhere.
Chariot: Small solar-focused team. Limited hours. Solar expertise when you reach them.
Frontier: 20-30 minute hold times. Website looks like 2012. Daily usage texts are actually useful. Nobody will proactively call you about anything.
The trade-off: Chariot’s limitations come from being a small company. Frontier’s limitations come from investing in lower rates. Neither is wrong—just don’t expect hand-holding from either.
If customer service matters, pay the TXU or Reliant premium. Neither Chariot nor Frontier is competing on support.
Deposit Policies
Both run credit checks. Both require conditional deposits.
Chariot: Good credit or AutoPay enrollment can waive deposits.
Frontier: Score above 650 typically means no deposit. Below that, $50-$150 upfront.
Neither offers prepaid. If your credit is rough, look at Payless Power or Discount Power instead.
The Verdict
Choose Chariot if:
- You have solar panels and want superior buyback rates
- Community solar programs interest you
- Genuine solar infrastructure matters more than price
- You’re committed to solar-first energy
Choose Frontier if:
- You don’t have solar panels
- Price is your primary consideration
- You want Centrica’s corporate backing
- Green certificates are sufficient for your conscience
The decision is simple:
- Solar panels → Chariot
- No solar panels → Frontier
Everything else is overthinking. Frontier saves you $200-$350/year. Chariot only beats that math if you’re generating solar power to sell back.
