Cirro Energy

Company Overview

Here’s the truth about Cirro Energy: They include green energy free—but their complaint rate should give you pause.

Cirro is owned by NRG Energy, same corporate parent as Reliant and Green Mountain. Different brand, same Fortune 500 backing. Every Cirro plan includes renewable energy by default—you don’t pay a “green premium” like you would at Green Mountain. That’s genuinely useful if you want eco-friendly electricity without the markup.

The catch: Cirro’s PUCT complaint rate runs above the industry average. Not terrible, but notably higher than siblings like Reliant. Some customers report billing disputes that drag on and customer service that’s less responsive than the premium NRG brands.

Mid-tier pricing puts Cirro between budget options like Frontier and premium names like Reliant. You’re not getting rock-bottom rates, but you’re not paying for Reliant’s rewards program either. Whether the green-included value proposition makes up for the complaint history is your call.

Where Cirro Energy Operates

Cirro serves the major deregulated areas of Texas including Dallas–Fort Worth, Houston, Austin-area communities, Corpus Christi, and regions covered by Oncor, CenterPoint, AEP Texas, and TNMP.

Like every retail electricity company in Texas, Cirro doesn’t operate in municipal utility areas like Austin proper or San Antonio.

Plans & Pricing

Smart Lock Fixed-Rate Plans Cirro’s bread and butter. Lock in a rate for 12, 24, or 36 months. Straightforward pricing without the free nights/weekends complexity.

Variable-Rate Plans Month-to-month options that fluctuate with market conditions. No contract, no stability.

Green Energy Every Cirro plan includes renewable energy—wind and solar. You don’t need to select a special “green” tier or pay a premium.

What They Don’t Offer:

• Prepaid plans
• Free nights/weekends
• Time-of-use pricing
• Solar buyback programs

Deposits & Credit

Cirro runs a credit check when you sign up. If your score meets their threshold, no deposit required. If not, expect to pay a deposit based on your estimated monthly usage—typically capped at two months’ worth.

Ways to avoid a deposit: provide a letter of credit from a previous electricity company showing 12 months of good payment history, or meet their credit requirements.

No prepaid option means no backdoor around the credit check.

Customer Service

Cirro’s service is… average. Phone support is available 7 days a week, but they close at 10pm Central. Not 24/7 like TXU or Reliant.

The good:

• 30-day Service Satisfaction Guarantee lets you cancel penalty-free if you’re unhappy
• Website and account management tools work fine
• NRG backing means they’re not going anywhere

The not-so-good:

• Above-average complaint rate with the PUCT
• Customer service hours aren’t 24/7
• Some customers report billing disputes that drag on

The Verdict

Cirro Energy makes sense if you want green energy without paying a green premium—and you don’t need prepaid or specialty plans. The NRG ownership provides stability, and the 30-day guarantee reduces your risk.

But that above-average complaint rate is worth noting. If customer service quality matters to you, companies like TXU or Reliant—despite their higher prices—have better track records.

Cirro sits in the middle: not the cheapest, not the most expensive, not the best service, not the worst. If “green energy standard” appeals to you and you’re okay with average service, they’re worth considering.
