The Corporate Reality

Two Fortune 500 brands from competing energy giants.

TXU Energy is Vistra Corp’s [NYSE: VST] flagship retail brand. Vistra also owns Ambit Energy, 4Change Energy, Veteran Energy, Express Energy, and TriEagle Energy. TXU gets Vistra’s best customer service investment, highest marketing spend, and premium pricing.

Discount Power is NRG Energy’s [NYSE: NRG] budget brand. NRG also owns Reliant, Direct Energy, Green Mountain Energy, and Cirro Energy. Discount Power operates under US Retailers LLC (PUCT #10177), the same legal entity as Cirro Energy. Discount Power absorbed Energy Texas customers in early 2024 and Summer Energy customers in mid-2024. NRG is investing in this brand as their price-leader play.

The comparison is straightforward: Vistra’s most expensive brand vs. NRG’s cheapest brand. Same grid, same wires, same electrons. Different overhead, different price.

What They Actually Sell

TXU’s lineup (7+ plan types):

• Fixed-rate (12-24 months, $150-$295 ETF)
• Variable-rate (Flex Forward)
• Free Nights & Solar Days
• Live Your Free (auto-switching free periods)
• Ultimate Season Pass (50% off peak months)
• Solar Buyback (rooftop solar credits)
• GreenUp add-on (100% RECs)

Discount Power’s lineup (3 plan types):

• Fixed-rate (12, 24, or 36 months, $150-$395 ETF)
• Bill Credit Bundle plans ($100-$125 credit at 1,000+ kWh)
• Variable-rate (month-to-month)

What Discount Power does not offer: Free nights, free weekends, time-of-use, solar buyback, prepaid, 100% green plans, rewards programs. Plans include approximately 20% renewable content—below the Texas grid average of roughly 31%.

The trade-off is simple: TXU sells every plan type imaginable. Discount Power sells cheap fixed-rate electricity and nothing else. If a simple fixed-rate plan covers your needs, you are paying $200-$360/year extra at TXU for features you will never use.

The Credit & Deposit Question

TXU: Credit check required. Conditional deposit. Waivers for age 55+, personal guarantee, family violence, medical indigency. Deposit split into two installments. No prepaid.

Discount Power: Credit check required. Score above 650 typically means no deposit. Below that, $100-$200 refundable deposit. Letter of credit from previous provider accepted. LITE-UP Texas program allows two-installment payment. No prepaid.

Neither offers prepaid. If your credit is rough and deposits are a barrier, look at Payless Power or Reliant’s Prepaid Power instead.

The Verdict

Choose TXU if you specifically need free nights, time-of-use pricing, solar buyback, or green energy plans. Also choose TXU if 24/7 customer support is genuinely important to your peace of mind. These are real features—but they cost $200-$360/year in premium pricing.

Choose Discount Power if you just want electricity at the lowest price from a financially stable company. A fixed-rate plan from Discount Power delivers identical power on the same grid for 15-20% less. No frills, no polish, no stadium sponsorships—just cheaper electricity. Discount Power’s 90-day satisfaction guarantee lets you cancel penalty-free if you are unhappy.

The honest math: Most Texans pick a plan, set up autopay, and never think about their electricity company again. If that describes you, Discount Power saves real money. TXU’s features only justify the premium if you will actually use them.
