NextEra-Backed Scale vs. Independent Digital-First
Both providers compete on simplicity over gimmicks, but they get there from very different starting points.
Gexa Energy
Backed by NextEra Energy, one of the largest power generators in the US, with access to wholesale markets and NextEra's wind/solar portfolio.
Best for: customers who want simple, low rates and value the financial stability of a large corporate parent.
Rhythm Energy
Independent and B Corp certified, founded in 2021 by former REP executives. Every plan is 100% renewable by default, and the entire experience — signup, billing, support — is built digital-first.
Best for: customers who want renewable energy without shopping for a separate green plan, and who are comfortable managing service primarily online.

Bottom Line
If renewable energy matters to you and you don't want to hunt for a separate green plan, Rhythm bakes it into every plan by default and backs it with B Corp certification. If you want the financial backing of a large corporate parent and don't need every plan to be renewable, Gexa is the safer, more established choice with a longer track record.

Frequently Asked Questions
Is Gexa or Rhythm Energy cheaper?
Both run lean, no-frills plan lineups, so their rates tend to land close together. Check the live rate table above for each provider's current range in your TDSP area, since exact pricing shifts over time.
Are Gexa and Rhythm owned by the same company?
No. Gexa Energy is owned by NextEra Energy Services, a subsidiary of NextEra Energy. Rhythm has no corporate parent — it's an independently owned company founded in 2021 by former executives from larger Texas retail electricity providers.
Is Rhythm actually 100% renewable, or just a marketing label?
Every Rhythm plan is backed by renewable energy certificates (RECs) matched to your usage, sourced from Texas wind and solar. This is the standard mechanism for "100% renewable" claims across the Texas market, including Gexa's Gexa Green plan — the difference is Rhythm applies it to its entire lineup by default rather than offering it as a separate green-tier plan.
