Overview

Why are you even comparing these two?

Same wires. Same grid. Same electrons. When your AC kicks on, Oncor delivers the power—not Reliant, not Frontier. They’re billing companies with different marketing budgets.

Here’s what Reliant won’t tell you: That rewards program you’ll probably forget to use? Those smart home bundles you don’t need? The polished app you’ll open twice? You’re paying 15-25% more for all of it. On a typical Texas home, that’s $250-500/year funding Reliant’s ad agency.

Frontier is owned by Centrica, a $30 billion British company. They could sponsor every stadium in Texas if they wanted. Instead, they skip the marketing circus and pass savings to you. Same electricity. Different overhead.

Company Backgrounds

Reliant Energy is NRG’s flagship Texas brand. Fortune 500 backing, massive marketing budget, the works. They launched in 2001 and have been one of the biggest players ever since.

Frontier Utilities started in 2008. Owned by Centrica, a $30 billion British company that also runs British Gas. They don’t advertise much because low prices are the marketing.

Both are financially stable. Frontier being “smaller” doesn’t mean risky—their parent company is huge.

The Price Difference

Let’s be direct: Frontier is almost always cheaper.

For a typical home using 1,000 kWh/month, Frontier usually runs 15-25% less than Reliant. That’s $20-40/month. $250-500/year.

Why? Reliant spends on marketing, rewards programs, app development, and bundle partnerships. That money comes from somewhere. Frontier spends on… lower rates.

Same electricity. Same wires. Different overhead.

What Reliant Offers That Frontier Doesn’t

Reliant Rewards - Points for paying bills, free movie tickets, discounts. Worth $50-100/year if you actually use it. Most people don’t.

Smart Home Bundles - Package electricity with Nest thermostats, home security. Convenient if you want one company for everything.

Polished App - Reliant’s app is genuinely good. Usage tracking, bill pay, outage alerts.

24/7 Phone Support - Call anytime. Frontier’s support has limited hours.

What Frontier Offers

Lower Prices - That’s the pitch. That’s the product.

Bilingual Support - Strong English/Spanish customer service. Reliant has it but Frontier does it better.

Simplicity - No rewards to track, no bundles to manage. Just electricity.

Customer Service

Reliant wins here. Better satisfaction scores, 24/7 availability, more support channels.

Frontier is… fine. They answer the phone during business hours. They solve problems. But if you need help at 2am, that’s a problem.

The Verdict

Reliant is a brand. Frontier is a utility.

Choose Reliant if:

  • You want rewards, apps, and smart home integration
  • Customer service availability matters
  • You’re willing to pay extra for the experience
  • Brand recognition makes you feel secure

Choose Frontier if:

  • You want the cheapest rate available
  • You just need electricity, nothing fancy
  • You value bilingual support
  • You’re fine calling during business hours if needed

The real question: Is Reliant’s extra stuff worth $300-500/year? For most people, no. But if you’ll actually use the rewards and want 24/7 support, it might be.
