The Corporate Reality

Frontier Utilities is NextEra Energy’s [NYSE: NEE] budget Texas brand. Sister company to Gexa Energy. NextEra is the largest energy company in North America—$190 billion market cap. Frontier competes on price and prepaid access, while Gexa handles the green flagship role.

Cirro Energy is NRG Energy’s [NYSE: NRG] mid-tier brand. Shares a legal entity (US Retailers LLC, PUCT #10177) with Discount Power—literally the same company with different branding. In NRG’s five-brand hierarchy, Cirro sits between Discount Power (cheaper) and Green Mountain (greener, pricier).

Frontier gets NextEra resources split two ways. Cirro gets NRG resources split five ways, with Reliant getting first priority. Customer service investment reflects this.

What They Actually Sell

Frontier’s lineup:

  • Fixed-rate plans (12, 24, 36 months) at 8.6-20.4 cents/kWh
  • Bill credit tiers: Saver Value (500 kWh), Saver Plus (1,000 kWh), Saver Deluxe/Premier (2,000+ kWh)
  • Variable-rate—month-to-month, no ETF
  • Prepaid: Power As You Go—no credit check, no deposit, no contract
  • 25-30% renewable energy content
  • $150 ETF on 12-month plans
  • 60-Day Happiness Guarantee

Cirro’s lineup:

  • Bill Bonus plans (12, 24 months) at 9.7-20.2 cents/kWh—credit at 1,000 kWh
  • Simple Advantage plans (12, 24 months)—clean fixed rate, no credit threshold
  • Variable-rate plan (periodically available)
  • Green energy included in all plans
  • $150 ETF on 12-month, $295 on 24-month plans

Frontier’s advantage: usage-matched tiers. The Saver Value plans work for apartments at 500 kWh. Saver Plus targets average homes at 1,000 kWh. Saver Deluxe/Premier handles large homes at 2,000+ kWh. You pick the tier that matches your actual usage.

Cirro’s advantage: Simple Advantage plans have zero bill credit math. A predictable fixed rate regardless of how much you use. Frontier doesn’t offer a comparable no-gimmick plan.

The Credit & Deposit Question

Frontier: Soft credit check for fixed-rate plans. Pass = no deposit. Fail = deposit required, OR switch to Power As You Go prepaid (no credit check, no deposit at all). Bilingual enrollment available.

Cirro: Standard credit check. Good credit = no deposit. Bad credit = $150-$300 deposit. Letter of credit from previous provider as alternative. No prepaid option.

Frontier’s prepaid option is the clear differentiator. If your credit is rough, Frontier gets you electricity without a deposit. Cirro turns you away unless you can pay up.

The Verdict

Choose Frontier if:

  • You need prepaid with no credit check—Power As You Go is a real safety net
  • Lower rates matter—Frontier starts about 1 cent/kWh cheaper
  • Usage-matched bill credit tiers fit your energy habits
  • Bilingual Spanish support is valuable to you

Choose Cirro if:

  • Green energy included in every plan matters to you
  • Simple Advantage plans with zero bill credit games are your style
  • A 25-year Texas track record gives you confidence
  • You want green without paying Green Mountain prices

Skip both if:

  • 100% renewable is non-negotiable—look at Gexa, Rhythm, or Chariot
  • You want free nights/weekends—look at Chariot or Direct Energy
  • You want the cheapest possible rate period—look at Discount Power (Cirro’s sister brand)
