Bottom Line: Two Fortune 200+ parents, completely different strategies. Frontier runs 20-30% cheaper because they skip the marketing circus. Reliant charges a premium for time-of-use plans, 24/7 support, a polished app, and rewards. If you just want cheap electricity and autopay, Frontier saves you $300-$500/year. If you will actively use free nights or need solar buyback, Reliant earns its premium.

The Corporate Reality

Both providers have massive corporate backing, but deploy that capital very differently.

Reliant Energy is NRG Energy’s [NYSE: NRG] Texas flagship. NRG spends on TV ads, Texans sponsorships, rewards programs, and app development—then passes those costs to you through higher rates. Reliant also sits alongside Direct Energy, Green Mountain Energy, Cirro Energy, Discount Power, Stream Energy, and XOOM Energy in the NRG family.

Frontier Utilities is owned by NextEra Energy Resources [NYSE: NEE], the largest energy company in North America by market cap ($190B+). NextEra also owns Gexa Energy (Frontier’s sister brand) and Florida Power & Light. Frontier could outspend Reliant’s marketing budget tomorrow. They just choose not to. The savings go into the rate instead.

The legal entity behind Frontier changed its name from “Frontier Utilities, LLC” to “Retail Energy Solutions, LLC” in August 2025 [PUCT filing]. Same plans, same service, same phone number. Nothing changed for customers.

Same grid. Same wires. Same electrons. The 20-30% price gap is pure overhead difference.

What They Actually Sell

Reliant’s Plans (12.5-20.6 cents/kWh at 1,000 kWh, CenterPoint)

• Fixed-rate (12 and 24-month): Standard locked-in rates. ETFs of $150 and $295.
• 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 free (up to 8/month). 100% solar.
• Prepaid Power: No credit check, no deposit, $75 minimum. Smart meter required.
• Solar Payback Plus: Buyback at ~4.3 cents/kWh fixed.
• Clear Flex (variable): Month-to-month, $9.95 base under 800 kWh.

Frontier’s Plans (8.6-20.4 cents/kWh at 1,000 kWh, CenterPoint)

• Bill credit plans (Saver Plus, Saver Value Plus, etc.): 12-month terms with $125 credit at 1,000+ kWh. The lowest rates depend on hitting the usage threshold. ETFs: $150.
• Straightforward plans (Light Saver, etc.): Rates without heavy bill credit dependency.
• Variable-rate: Month-to-month, no contract.
• Power As You Go (prepaid): No credit check, no deposit. Higher per-kWh rate.

No free nights. No free weekends. No time-of-use. No solar buyback. Frontier competes on rate, not plan variety.

The Price Gap in Real Numbers

At 1,000 kWh/month:

• Frontier’s cheapest (Saver Plus 12 with bill credit): ~8.6 cents/kWh = ~$86/month
• Reliant’s cheapest fixed-rate: ~12.5 cents/kWh = ~$125/month
• Gap: ~$39/month, ~$468/year

Even comparing mid-range plans, Frontier typically saves $20-$30/month. Over a year, that is $240-$360. Over a 24-month contract, $480-$720.

The catch: Frontier’s cheapest rates come from bill credit plans. Miss the 1,000 kWh threshold and your effective rate jumps. Reliant’s basic fixed-rate plans are more predictable across usage levels.

The Credit & Deposit Question

Reliant runs a standard credit check. Good credit means no deposit. Multiple waiver paths available (letter of credit, age 65+, military, medical/family violence). Prepaid Power skips the credit check entirely—$75 to start.

Frontier runs a soft credit check—it will not hurt your credit score. Pass it and no deposit. Below threshold, you can pay the deposit (refunded after 12 on-time payments), switch to Power As You Go prepaid (no credit check, no deposit), provide a credit reference letter, or qualify for an age/family violence exemption.

Both have prepaid options for customers who cannot clear a credit check. The key difference: Frontier’s soft pull does not appear on your credit report. Reliant’s standard credit check does.

Bilingual Support

Frontier offers native-speaker English/Spanish bilingual customer service—not a phone tree afterthought but actual bilingual staff. This is a genuine differentiator for Spanish-speaking households. Reliant has Spanish support available but Frontier does it better.

Customer Service

Reliant: 24/7 phone (1-866-222-7100) and live chat. Best-in-class mobile app. Hold times typically under 15 minutes. 90-day plan-switching window without ETF. The catch: every interaction becomes an upsell pitch for home services and protection plans.

Frontier: Mon-Fri 7am-6pm, Sat 8am-2pm (1-866-926-8192). No Sunday support. Basic but functional app. 60-day happiness guarantee (switch Frontier plans without ETF). In-person payments at Ace Cash Express and CheckFreePay locations.

The service gap matters most outside business hours. If something goes wrong at midnight on a Saturday, Reliant answers. Frontier does not. For outages, you call your TDU (Oncor, CenterPoint) regardless—neither provider can restore your power.

The Verdict

Choose Reliant if you will actively use its specialty plans. Truly Free Nights/Weekends can produce effective rates that compete with Frontier’s budget pricing—but only if you genuinely shift 40%+ of usage to the free window. Solar Payback Plus fills a gap Frontier cannot touch. The 24/7 support and app quality are real advantages if you interact with your provider regularly.

Choose Frontier if price is the priority. At 20-30% below Reliant, Frontier saves $300-$500/year on the same grid with the same electrons. NextEra’s Fortune 200 backing means financial stability is not a concern. The 60-day happiness guarantee lets you test without commitment. Set up autopay, forget about it, and bank the savings.

The bottom line for most people: If you pay your bill online, never call customer service, and do not care about free nights or solar buyback, you are paying Reliant $300-$500/year for an app you will open twice and rewards you will forget to redeem. Frontier delivers the same electricity for less.
