Ranges reflect all current plans on file for each provider in that TDSP area, not a single featured plan — the exact rate you qualify for depends on your specific ZIP code and usage level.
Compare usage credits and contract terms
A provider-wide price range does not tell you which plan costs least for your household. Compare the Electricity Facts Labels at 500, 1,000 and 2,000 kWh and check monthly fees, credits and cancellation terms.
Gexa advertises fixed-rate, variable-rate and usage-credit plans, as well as specialized EV and solar options. Do not assume its entire lineup is a simple fixed rate or that marketing costs explain the difference from a TXU offer.

Frequently Asked Questions
Is TXU or Gexa Energy cheaper?
Neither provider is always cheaper. Compare the specific offers at your ZIP code and usage, including credit thresholds, monthly fees and cancellation terms. A low advertised price at 1,000 kWh may not be lowest in a low-usage month.
Are TXU and Gexa owned by the same company?
No. TXU Energy is part of Vistra and Gexa is part of NextEra Energy. They are different corporate groups; compare plan terms rather than assuming ownership determines price.
Why can a Gexa advertised rate look lower?
Gexa offers usage-credit plans, so qualifying credits can reduce the advertised average price at selected usage levels. Check whether you qualify in each month. Lower marketing spending is not a verified explanation for the price of an individual offer.
