Best Texas Energy Providers Ranked for 2026

ElectricRates.org's provider rankings use data, not ad spend. We weighted five factors:

Rate competitiveness (30%) — Average fixed-rate pricing at 1,000 kWh compared to the market median.

PUCT complaint ratio (25%) — Complaints per 1,000 customers filed with the Public Utility Commission of Texas.^[1]

Plan variety (15%) — Range of contract lengths, plan types (fixed, variable, free nights, solar buyback, prepaid).

Customer service (15%) — Response times, resolution rates, and third-party review scores from Google, BBB, and Trustpilot.

Billing transparency (15%) — How clearly the Electricity Facts Label matches the actual bill. Hidden fees and misleading advertising lower this score.

Gexa Energy earns the top spot in 2026. Gexa consistently offers some of the lowest fixed rates in the state—often 2-3 cents below the market average at 1,000 kWh. As a NextEra Energy subsidiary, Gexa has financial stability behind it. All plans include 100% renewable energy at no premium. PUCT complaint ratio stays well below average.

Rhythm Energy takes second place. Rhythm combines competitive rates (9-13 cents per kWh) with a modern app, transparent billing, and 100% renewable plans. The company launched in 2021 and has built a strong reputation quickly. Low PUCT complaint numbers. Excellent Google review scores averaging above 4 stars.

4Change Energy wins the best value category. 4Change offers rates in the 9-12 cent range while donating to Texas charities with every bill. Plans are straightforward—no gimmicks, no hidden fees. Fixed-rate contracts come in 12 and 24-month terms. The complaint ratio sits among the lowest in the market.

Frontier Utilities earns recognition for consistent value. Frontier keeps plans simple: competitive fixed rates, minimal fees, and bilingual customer support. Rates typically land between 9-13 cents per kWh. Frontier won't win flashiest-provider awards, but the company delivers reliable service at fair prices. That's what most people actually want.

Green Mountain Energy has been selling 100% renewable electricity in Texas since 1997—longer than any other provider. Green Mountain offers wind and solar plans with rates around 11-15 cents per kWh. The premium over conventional plans has shrunk significantly. Strong environmental credentials backed by actual renewable energy certificates.

Chariot Energy stands out for solar customers. Chariot offers solar buyback plans that credit you at retail rates for excess generation. Standard plans start around 10-13 cents per kWh. The company also offers community solar options for renters. If you have rooftop panels or want solar without installing anything, Chariot is worth checking.

TXU Energy is the largest Texas REP by customer count. TXU offers the widest plan selection: fixed, variable, free nights, free weekends, solar buyback, and EV plans. Rates range from 11-16 cents per kWh. The downside: TXU's rates rarely rank among the cheapest. You pay a premium for brand recognition and plan variety.

Reliant Energy (NRG subsidiary) anchors the Houston market. Reliant offers competitive rates, a solid rewards program, and reliable customer service. Rates sit in the 10-15 cent range. Higher PUCT complaint volume partly reflects Reliant's large customer base. The complaint ratio is average—not great, not terrible.

Constellation (Exelon subsidiary) has been expanding aggressively in Texas residential markets. Constellation offers competitive fixed rates and a well-designed online portal. Worth comparing if you see them in your ZIP code.

Champion Energy serves both residential and commercial customers. Champion earned a strong reputation in the business market and is now pushing into residential with competitive rates and no-gimmick plans.

Energy Texas (Rhythm Energy subsidiary) operates as a smaller brand with targeted promotional rates. Energy Texas occasionally offers the lowest rate in specific ZIP codes. Check availability in your area.

Some Texas REPs have patterns worth noting.

High complaint ratios. Any provider with a PUCT complaint ratio above 1.0 per 1,000 customers deserves extra scrutiny. Check our complaint dashboard for current numbers.

Teaser rates. Some providers advertise impossibly low rates that apply only at exactly 1,000 kWh due to bill credits. At 800 or 1,200 kWh, you pay significantly more. Always check the EFL at all three usage levels.

Auto-renewal to variable. Many contracts auto-renew to variable rates that can spike 50-100% higher. Set a calendar reminder 30 days before your contract expires. Texas law requires providers to send an expiration notice, but don't rely on it.
