Overview

Two solid mid-market options with different value propositions.

Frontier Utilities saves you $200-$350/year compared to TXU and Reliant. Budget pricing from Centrica plc, a British energy giant. No marketing fluff. Basic electricity at good rates. Green plans available but cost extra.

Cirro Energy includes renewable energy in every plan at no extra charge. NRG Energy owns them—same parent as Reliant and Green Mountain. Mid-tier pricing without the Green Mountain markup. The 30-day satisfaction guarantee reduces your risk.

The question: Is free green energy worth 10-15% higher base rates?

The Green Energy Calculation

This comparison hinges on whether you want renewable energy.

If you don’t care about green:

• Frontier: Budget rates, conventional electricity
• Cirro: Paying 10-15% more for green you didn’t ask for
• Winner: Frontier

If you want green energy:

• Frontier: Budget rate + green premium
• Cirro: Mid-tier rate with green included
• Winner: Depends on the specific rates

Do the math: Check if Frontier’s 100% renewable plan costs more or less than Cirro’s standard plan. Often they’re close, making Cirro’s free green a genuine value.

Pricing Reality

On a typical 1,200 kWh/month Texas home:

Frontier Utilities (standard): Around 9-11 cents/kWh. $110-$130/month.

Frontier Utilities (100% renewable): Around 10-12 cents/kWh. $120-$145/month.

Cirro Energy (green included): Around 10-12 cents/kWh. $120-$145/month.

The insight: If you want green energy, Frontier and Cirro often land at similar prices. Cirro’s “free green” is actually a different pricing structure, not charity. They’re betting green-conscious customers won’t compare against Frontier’s green option.

If you don’t want green energy, Frontier saves $120-$180/year on standard plans.

Company Backgrounds

Frontier Utilities is owned by Centrica plc [LSE: CNA], worth more than Vistra (TXU’s parent). British energy giant. Houston operations since 2008. They skip marketing budgets and pass savings to customers.

Cirro Energy is owned by NRG Energy [NYSE: NRG], a $70+ billion company. Same parent as Reliant, Direct Energy, and Green Mountain. Texas-headquartered corporate infrastructure. 24 years in the state.

Both have unquestionable financial stability. Cirro has deeper Texas roots. Frontier has lower overhead.

Customer Service

Neither company excels here. Different problems, similar frustration.

Frontier issues:

• 20-30 minute phone hold times
• Website looks dated
• App? What app?
• Complex issues drag on

Cirro issues:

• Above-average PUCT complaint rate
• Billing disputes take 3-4 calls to resolve
• Phone support closes at 10pm (no 24/7)
• Lower priority than NRG’s flagship Reliant

The trade-off: Frontier’s issues are about minimal investment. Cirro’s issues are about being a second-tier NRG brand. Neither will win awards. Both will eventually solve your problems.

The Satisfaction Guarantee

Cirro’s 30-day satisfaction guarantee is genuinely valuable:

• Sign up
• Test the service
• Cancel penalty-free within 30 days if unhappy

That’s real risk reduction. Frontier offers nothing comparable.

If you’re uncertain about switching, Cirro’s guarantee has meaningful value. Try them, verify the bills match expectations, leave free if they don’t.

Plan Options

Frontier offers:

• Fixed-rate plans (1-36 months)
• Variable-rate plans
• 100% renewable options (extra cost)
• Simple structures, no gimmicks

Cirro offers:

• Fixed-rate plans (1-36 months)
• Variable-rate plans
• Green energy included in every plan
• Simple structures, no gimmicks

Neither has free nights, prepaid, time-of-use, or specialty plans. Both focus on straightforward electricity. The difference is green energy default (Cirro) vs optional (Frontier).

Deposit Policies

Both run credit checks. Both want deposits from customers scoring below 650. Neither offers prepaid.

No meaningful difference here. If credit is your barrier, look at Payless Power or Discount Power.

The Verdict

Frontier wins on price for non-green customers. Cirro wins on green-included convenience. The gap narrows if you want renewable energy.

Choose Frontier Utilities if:

• You want the lowest rates from a stable corporate parent
• Green energy is nice-to-have but not essential
• You pay bills online and don’t need customer service hand-holding
• You’d rather choose your own green plan than have it bundled
• Budget matters more than environmental defaults

Choose Cirro Energy if:

• Green energy included free in every plan sounds right
• You want the 30-day satisfaction guarantee safety net
• You prefer NRG’s Texas infrastructure
• You’d pay similar rates for green anyway
• The environmental default feels better than choosing to upgrade

The real answer: If you want green energy, compare Frontier’s 100% renewable rate against Cirro’s standard rate. Often they’re close. If you don’t want green, Frontier saves you $120-$180/year on identical physical electricity.
