Cirro Energy

Quick Facts

Is Cirro Energy good? Cirro includes green energy free in every plan—but has above-average PUCT complaints, making it a mixed choice despite NRG backing.

• Parent Company: NRG Energy (NYSE: NRG)
• Years in Texas: 24
• Best For: Customers who want green energy included without paying Green Mountain’s premium
• Avoid If: You need prepaid electricity—Cirro doesn’t offer it
• Deposit Required: Conditional (credit score 650+ typically means no deposit)

Company Overview

Cirro includes green energy in every plan at no extra charge. That’s genuinely useful—Green Mountain charges 15-25% more for the same thing. But Cirro’s above-average complaint rate with PUCT should give you pause.

NRG Energy owns Cirro, along with Reliant and Green Mountain. Same Fortune 500 backing, different marketing angle. Cirro targets customers who want renewable energy without paying Green Mountain’s premium or dealing with Reliant’s constant upselling.

The complaint data matters. Cirro runs notably higher than sibling brand Reliant on PUCT complaints [PUCT Complaint Database, Q4 2025]. We’ve seen patterns of billing disputes that drag on and customer service that’s less responsive than NRG’s flagship brands. Same corporate infrastructure, different priority level.

Mid-tier pricing: cheaper than Reliant, more expensive than Frontier. You’re not getting rock-bottom rates, but you’re not paying for rewards programs you’ll never use either.

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 credit checks on everyone. Score above 650? No deposit. Below that? You’re paying 1-2 months’ estimated usage upfront—typically $150-$300.

Ways around a deposit: letter of credit from your previous provider showing 12 months of on-time payments. That’s it.

Cirro doesn’t offer prepaid. If your credit is rough, you can’t use the green-energy-included benefit—you’ll need to look at Payless Power or Discount Power’s prepaid options first.

Customer Service

Cirro’s customer service is a tier below NRG’s flagship brands. Same corporate infrastructure, lower priority.

The good:

• 30-day Satisfaction Guarantee: Cancel penalty-free if you’re unhappy. This is real and useful.
• Website and account tools: Functional. Bill pay works. Usage history exists.
• NRG backing: $70B+ company. No bankruptcy risk.

The not-so-good:

• Phone support closes at 10pm Central. Not 24/7 like TXU or Reliant.
• Above-average PUCT complaint rate [PUCT Complaint Database, Q4 2025]
• Billing disputes drag on. Multiple customers report needing 3-4 calls to resolve issues.

The Bottom Line

Cirro makes sense for one specific person: you want green energy without paying Green Mountain’s 15-25% premium, and you’re willing to accept average customer service as the trade-off.

The 30-day guarantee reduces your risk. NRG ownership provides stability. Green energy included by default is genuinely valuable.

But if customer service matters to you—really matters—the complaint data says pay the TXU or Reliant premium. Cirro inherited NRG’s infrastructure without inheriting their customer service investment.
