Bottom Line: Gexa wins for most Texans. Same electricity, 10-20% cheaper, 100% renewable by default, backed by the world’s largest renewable energy generator. TXU only wins if you specifically need free nights, time-of-use plans, or 24/7 phone support.
The Corporate Reality
Two Fortune 500 energy giants, very different business philosophies.
TXU Energy is Vistra Corp’s [NYSE: VST] flagship Texas brand. Vistra generates power from natural gas, nuclear, coal, and renewables. TXU’s default plans are conventional energy. Green costs extra.
Gexa Energy is owned by NextEra Energy [NYSE: NEE], the world’s largest generator of wind and solar energy with a market cap above $190 billion. Gexa committed in 2019 to making every residential plan 100% renewable through RECs. NextEra also owns Frontier Utilities—Gexa’s budget-tier sister brand.
The corporate backing tells you something. TXU’s parent generates fossil fuel power and sells green as an add-on. Gexa’s parent is literally the world’s largest renewable energy company and bakes green into every plan at no premium. Same grid, different corporate DNA.
What They Actually Sell
TXU’s lineup (7+ plan types):
- Fixed-rate (12-24 months, $150-$295 ETF)
- Variable-rate (Flex Forward, month-to-month)
- Free Nights & Solar Days (free energy charges 9 PM-6 AM, daytime rate 18-22 cents/kWh all-in)
- Live Your Free (auto-selects best free period each month)
- Ultimate Season Pass (50% off peak summer/winter)
- Solar Buyback (credits for rooftop solar excess)
- GreenUp add-on (100% RECs on any plan, extra cost)
Gexa’s lineup (4 plan types):
- Fixed-rate (12, 24, 36 months, $150-$295 ETF)
- Variable-rate (Gexa Flex, month-to-month)
- Solar Buyback (Solar Export Saver, Battery Benefits)
- EV Charging (free electricity 11 PM-5 AM for EV owners)
What Gexa does not offer: Free nights or free weekends plans, time-of-use pricing outside EV hours, rewards programs.
The key difference: TXU offers more plan structures. Gexa offers fewer plans but every single one is 100% renewable and typically 10-20% cheaper. Gexa also includes a 60-Day Happiness Guarantee—switch to a different Gexa plan with no penalty within your first 60 days.
The Credit & Deposit Question
TXU: Credit check required. Conditional deposit. Waivers for age 55+, personal guarantee, family violence, medical indigency. No prepaid option.
Gexa: Soft credit pull (won’t affect your credit score). $400 deposit if required. Waivers for utility credit history letter (no more than 1 late payment in 12 months), age 65+, family violence victim status. No prepaid option.
Neither offers prepaid. Gexa’s soft pull is a minor advantage—TXU’s check type is not publicly specified. Gexa’s $400 deposit when triggered is on the higher side.
The Verdict
Choose TXU if you specifically need free nights, time-of-use pricing, or the season pass plan. These are genuine features Gexa cannot match. Also choose TXU if 24/7 phone support matters—Gexa closes at 8 PM weekdays, 2 PM Saturday, and is completely closed Sunday.
Choose Gexa if you want a simple fixed-rate plan at a competitive price with 100% renewable energy included. No upcharge for green. NextEra’s $190B+ backing means Gexa is not going anywhere. The EV Charging plan with free overnight electricity is a strong option for electric vehicle owners.
Skip both if you want the absolute cheapest rate. Frontier Utilities (Gexa’s NextEra sister brand) and 4Change Energy often undercut Gexa by another few percent. But Gexa’s 100% green commitment at near-budget pricing is hard to beat for the environmentally conscious rate shopper.
