Bottom Line: Same NRG parent, different strategies. Reliant charges premium rates for features and app quality. Cirro includes green energy free but has higher complaint rates. Pick your trade-off.
The Short Answer
NRG owns both companies. This is the same corporation selling electricity at two different price points with two different feature sets.
Reliant is the flagship brand with rewards programs, the best app in Texas, and every plan type you can imagine. You’re paying for customer service investment and marketing spend.
Cirro includes green energy in every plan at no extra charge and offers a 30-day satisfaction guarantee. You’re paying less, getting renewable energy, but dealing with above-average PUCT complaints.
The NRG Family Tree
Understanding who owns what helps you shop smarter:
NRG Energy owns:
- Reliant Energy (premium brand with rewards)
- Green Mountain Energy (renewable specialist—expensive)
- Cirro Energy (green-included mid-tier)
- Pennywise Power (budget fixed-rate)
- Discount Power (budget prepaid)
Cirro exists to capture customers who want green energy but won’t pay Green Mountain’s 15-25% premium. It’s NRG’s budget green option.
The Green Energy Difference
Reliant: Green energy is an optional add-on. Select their renewable plan and pay more. Most customers don’t.
Cirro: Every plan includes 100% renewable energy at no premium. Wind and solar sourced without the upcharge.
If green energy matters but your budget doesn’t stretch to Green Mountain prices, Cirro makes sense. You’re getting renewable energy without paying premium rates.
The Customer Service Problem
Here’s where Cirro falls short: PUCT complaint data shows Cirro runs notably higher than sibling brand Reliant.
Same corporate infrastructure. Different service priority. NRG put their customer service investment into Reliant, the flagship brand. Cirro inherited the infrastructure without the support team focus.
What this means:
- Billing disputes may drag on longer
- Phone support closes at 10pm (not 24/7 like Reliant)
- Multiple customers report needing 3-4 calls to resolve issues
The 30-day satisfaction guarantee helps—you can cancel penalty-free if something goes wrong early. But that’s a safety net, not a solution.
Plan Options
Reliant offers everything:
- Fixed-rate (12-36 months)
- Variable-rate
- Free nights and weekends
- Prepaid (Reliant Flex Pay)
- Time-of-use
- Green energy (optional)
- Solar buyback
Cirro offers:
- Fixed-rate (12-36 months)
- Variable-rate
- Green energy included in all plans
- 30-day satisfaction guarantee
If you need prepaid or free nights plans, Reliant wins by default. Cirro doesn’t compete in specialty categories.
The Math
On a typical 1,200 kWh/month household:
Reliant (standard): ~12-14¢/kWh = ~$168/month Reliant (green): ~14-16¢/kWh = ~$180/month Cirro (green included): ~10-12¢/kWh = ~$144/month
Annual difference vs Reliant standard: $250-$300 Annual difference vs Reliant green: $400-$500
If you want green energy, Cirro saves you $400+ per year compared to Reliant’s green plans. That’s significant.
The Verdict
Choose Reliant if:
- Customer service quality matters more than price
- You want 24/7 support that actually answers
- You need prepaid, free nights, or specialty plans
- You’ll use Reliant Rewards
- You’re willing to pay premium for a polished experience
Choose Cirro if:
- You want green energy without paying Green Mountain prices
- The 30-day satisfaction guarantee reduces your risk
- You’re okay with basic customer service
- You don’t need prepaid or specialty plans
- $250-$300/year in savings matters
The honest take: Cirro’s green-included pricing is genuinely valuable—Green Mountain charges much more for the same thing. But the customer service gap is real. If you can handle occasional frustration with support, Cirro saves you money on renewable energy. If customer service quality keeps you up at night, pay Reliant’s premium.
