Bottom Line: Discount Power is cheaper by 1-2 cents/kWh. Rhythm gives you 100% renewable energy, the best app, and demand response credits that narrow the gap. If green energy matters at all, Rhythm’s premium is small. If it genuinely doesn’t, Discount Power saves you $130-$180/year.
The Corporate Reality
Different companies for different values.
Rhythm Energy is Goldman Sachs-backed. Five years old. Every plan 100% renewable. Best app in the market. Growing nationally after acquiring Inspire Clean Energy in 2025. Built from scratch to prove green energy doesn’t require premium pricing.
Discount Power is NRG Energy’s [NYSE: NRG] budget brand. Shares a legal entity with Cirro Energy (US Retailers LLC, PUCT #10177). NRG also owns Reliant, Green Mountain, and Direct Energy. Discount Power’s job: be the cheapest option in NRG’s portfolio. No frills, no green story, just low rates.
The irony: NRG charges a significant premium for 100% renewable through Green Mountain. Rhythm delivers 100% renewable at barely above Discount Power’s rates. Rhythm is doing what Green Mountain should be doing—green energy without the markup.
What They Actually Sell
Rhythm’s lineup:
- Fixed-rate plans (12, 13, 23 months) at 10.8-19.4 cents/kWh—all 100% renewable
- PowerShift: free smart thermostat + $15/month credit, or $5/month with your own
- Solar buyback with time-of-use pricing, unlimited credit rollover
- Rhythm Rewards points
- 30-day test drive with $0 ETF
- ETF: $10-$20 per remaining month
- $150 ETF reimbursement from previous provider

- Bill Credit Bundle plans (1,000 or 2,000 kWh thresholds)
- Variable-rate—month-to-month, no ETF
- ~20% renewable, no green option
- $150 ETF on 12-month, $295 on 24-month, $395 on 36-month
- 90-day satisfaction guarantee
At 1,000 kWh: Rhythm at 10.8 cents ($108). Discount Power around 9.7 cents ($97). $11/month or $132/year. With Rhythm’s PowerShift ($15/month free-thermostat plan), the gap flips—Rhythm becomes cheaper once you factor in the credit.
The Green Reality
Rhythm: 100% renewable on every plan. Has never sold a fossil-fuel plan.
Discount Power: ~20% renewable. Below the Texas grid average of ~31%. No green upgrade available. NRG sends green customers to Green Mountain at premium pricing.
The gap is 80 percentage points. For 1-2 cents more per kWh, Rhythm delivers five times the renewable content. Whether that matters is a personal value judgment, but the price premium for going 100% green is genuinely small here.
The Credit & Deposit Question
Rhythm: Standard credit check. Fail = deposit or non-refundable Deposit Alternative Fee. Waivers for letter of credit, age 65+, family violence. No prepaid.
Discount Power: Credit check, 650+ typically no deposit. Below = $100-$200 deposit. Letter of credit accepted. No prepaid.
Discount Power’s lower deposit range ($100-$200 vs Rhythm’s variable) may be easier if your credit is borderline. Neither offers prepaid.
The Verdict
Choose Rhythm if:
- 100% renewable energy matters to you—the premium is 1-2 cents/kWh
- The best app and weekly Smart Alerts improve your electricity experience
- PowerShift credits ($5-$15/month) close or eliminate the rate gap
- Solar buyback fits your setup
- The 30-day test drive removes all risk
Choose Discount Power if:
- Green energy genuinely doesn’t factor into your decision
- You want the lowest possible rate from a Fortune 500 parent
- The 90-day satisfaction guarantee gives you more testing time
- Simple fixed-rate plans without innovation complexity appeal to you
Skip both if:
- You need prepaid—look at Payless Power or Frontier Utilities
- You want 100% green at the cheapest rate—look at Gexa Energy (8.6 cents, also 100% green)
- You want free nights/weekends—look at Chariot or Direct Energy
