Bottom Line: NRG Energy owns both companies. Reliant is the premium brand. Discount Power is the budget brand. Same corporate parent, same grid, same electricity—10-20% price difference. That gap funds Reliant’s rewards program, app development, 24/7 support, and Texans sponsorships. Whether those features are worth $200-$400/year depends on whether you will actually use them.

The Corporate Reality

NRG Energy owns both Reliant and Discount Power. This is not a comparison between competitors. This is NRG’s premium brand vs NRG’s budget brand.

NRG [NYSE: NRG] acquired Discount Power from Volterra Energy Holdings in late 2018. Since then, Discount Power has become NRG’s landing pad for budget acquisitions—absorbing Energy Texas customers in early 2024 and Summer Energy customers in mid-2024. NRG also owns Direct Energy, Green Mountain Energy, Cirro Energy, Stream Energy, and XOOM Energy.

Discount Power and Cirro Energy actually share the same legal entity: US Retailers LLC (PUCT Certificate #10177). Same company, different branding. Discount Power targets price-first shoppers. Reliant targets customers who want features and brand recognition.

The math is simple. Reliant’s rates on ComparePower run 12.5-20.6 cents/kWh at 1,000 kWh [CenterPoint, April 2026]. That premium pays for Reliant Rewards, the polished app, 24/7 support, and the Texans sponsorship. Discount Power strips all of that and passes the savings to your bill.

Same wires. Same grid operator. Same electrons. You are choosing how much of your electricity payment goes to overhead.

What They Actually Sell

Reliant’s Full Menu

• Fixed-rate plans: 12 and 24-month terms. ETFs of $150 (12-month) and $295 (24-month).
• Truly Free Nights (100% solar): Free 8 PM to 6 AM. Assumes 42% nighttime usage.
• Truly Free Weekends (100% solar): Free 8 PM Friday through midnight Sunday.
• Flextra Credits: 2 highest-usage days per week are free (up to 8/month). 100% solar.
• Prepaid Power: No credit check, no deposit, $75 minimum. Requires smart meter.
• Solar Payback Plus: Buyback at ~4.3 cents/kWh fixed.
• Clear Flex (variable): Month-to-month, $9.95 base under 800 kWh.

Discount Power’s Stripped-Down Options

• Fixed-rate plans (Wise Buy, Essential Saver): 12, 24, or 36-month terms. ETFs of $150, $295, $395 respectively.
• Bill Credit Bundle plans: Low headline rates with a credit at 1,000 or 2,000 kWh threshold. Miss the threshold, pay the full base rate.
• Variable-rate: Month-to-month, no contract. Rate floats with market conditions.

That is the entire lineup. No free nights. No free weekends. No time-of-use. No prepaid. No solar buyback. No 100% renewable option. Discount Power sells cheap electricity and nothing else.

Where Discount Power Wins

On a household using 1,000 kWh/month, Discount Power typically runs 10-20% below Reliant’s comparable fixed-rate plans. That translates to $15-$30/month or $200-$400/year in savings.

Discount Power’s bill credit plans can push effective rates even lower for consistent 1,000+ kWh users. A plan at 9.7 cents/kWh (at 1,000 kWh with the credit) vs Reliant’s 12.5 cents saves roughly $336/year at that usage level.

Where Reliant Wins

Reliant’s advantage is plan diversity. If you will genuinely shift 40%+ of your usage to free hours, the Truly Free Nights plan can produce effective rates that beat even Discount Power’s budget pricing. The math works for households that run laundry, dishwashers, EV charging, and pool pumps overnight.

The Flextra Credits plan—8 free days per month—has no equivalent anywhere in the NRG family.

Reliant’s solar buyback fills a gap Discount Power cannot touch. If you have rooftop panels, Discount Power is not even in the conversation.

The Credit & Deposit Question

Reliant runs a credit check. Good credit means no deposit. Below threshold, you pay a deposit or use one of six waiver paths (letter of credit, letter of guarantee, age 65+, active military, medical/family violence certification). Or skip the credit check entirely with Prepaid Power ($75 minimum).

Discount Power runs a credit check. Score above 650 typically means no deposit. Below that, expect $100-$200 refundable deposit. Options are more limited: letter of credit from previous provider, or LITE-UP Texas installment plan for qualifying low-income customers. No prepaid alternative exists.

If your credit is rough, Reliant gives you an escape hatch that Discount Power does not. Reliant’s Prepaid Power plan requires no credit check and no deposit. Discount Power will simply require the deposit or turn you away.

Customer Service: The NRG Hierarchy

NRG puts its customer service investment into Reliant first. Budget brands get what is left.

Reliant: 24/7 phone (1-866-222-7100) and live chat. Best-in-class mobile app with real-time usage, projected bills, EV scheduling, and solar tracking. Hold times typically under 15 minutes. The catch: constant upselling on home services, protection plans, and smart thermostats.

Discount Power: Daily 7am-10pm Central (1-877-455-4674). Mobile app for bill pay and basic usage. 90-day satisfaction guarantee. Spanish language support. The catch: longer hold times, no proactive communication about rate changes or contract expirations, billing disputes take multiple contacts to resolve.

The service gap is real but narrower than you might expect for daily operations. Where it matters most: after-hours emergencies and billing disputes. If something goes wrong at midnight, Reliant answers. Discount Power does not.

The Verdict

Choose Reliant if you will genuinely use what the premium buys. Truly Free Nights/Weekends are real products that can save money for the right household. The prepaid option solves credit problems that Discount Power cannot. Solar buyback fills a real need. The 24/7 support and app quality are measurably better.

Choose Discount Power if you want the cheapest NRG electricity and nothing else. Set up autopay, forget about it, and save $200-$400/year vs Reliant. Same Fortune 500 parent, same grid, same electrons. You are cutting overhead, not cutting quality of electricity.

The honest math: Most people do not use rewards programs, do not shift usage to free hours, and do not call customer service. For the majority of set-it-and-forget-it electricity customers, Discount Power saves real money every month while delivering identical electricity from the same corporate parent. Reliant’s premium only makes sense for the minority who will actively use the features.
