On the good side: Big company stability, Some inovative plans, lots of ways to pay your bill, an app, usage tracking, and modern online conveniences youd expect from a top company. Downside: Its a premium brand. That means you pay higher rates. 20% on average.

Rates Comparison
On a pure rate basis, Reliant consistently beats TXU. In the Houston (CenterPoint) service area, Reliant's Power Savings plans advertise 11.9¢/kWh - the lowest rate either company offers - versus TXU's best rate of 14.2¢/kWh on the Clear Deal 12. In Dallas (Oncor), the gap persists: 12.9¢ (Reliant) vs. 14.5¢ (TXU).
Watch out for bill-credit plans. Reliant's lowest-advertised rates (11.9¢) are on "Bill Credit" plans, which only apply a $50 discount when you use at least 1,000 kWh/month. Use less, and your effective rate jumps significantly - as high as 19.9¢/kWh at 500 kWh. TXU's best rates are "Tiered Rate" plans with their own threshold traps. For the most predictable bill, look for a fixed-rate plan from either provider.

Which Is Best for Your Situation?
The right provider depends heavily on your home size, usage habits, and priorities. Here's how each company stacks up for different customer types.
Apartment Dwellers (under 1,000 kWh)
Neither - Shop Elsewhere
Both providers charge premium rates, and Reliant's bill-credit plans actually penalize low-usage customers. A value brand will serve apartment residents better.
Average Home (1,000-1,500 kWh)
Reliant Energy
Reliant's Power Savings plans are most competitive right at the 1,000 kWh sweet spot where the $50 bill credit kicks in, bringing effective rates down sharply.
Large Home (2,000+ kWh)
Reliant Energy
Reliant's average bill for 2,000 kWh is $329/mo vs. TXU's $449/mo - a $120/month difference that adds up fast in a Texas summer.
EV Drivers / Night Chargers
TXU Energy
TXU's Free Nights & Solar Days 12 plan offers a window of free electricity - ideal for customers who charge EVs or run appliances overnight.
Solar Panel Owners
TXU Energy
TXU offers dedicated solar-friendly plans (Solar Value 12, Solar Saver 12). Reliant has faced criticism for not crediting expired-contract solar customers for generated power.
Green Energy Priority
TXU Energy
TXU's Solar Value 12 is rated 100% green energy. Reliant's Conservation plans encourage efficiency but don't match TXU's renewable commitment.
No Long-Term Contract
TXU Energy
TXU's Flex Forward plan is month-to-month with no cancellation fee. Reliant's shortest contract is 12 months with a $150 ETF.
Small Business
Reliant Energy
Reliant offers commercial electricity under the NRG brand at rates roughly 20% below the residential average - notably competitive for business accounts.
Plan Types Explained
Understanding the plan structure is just as important as the advertised rate. Both companies use pricing mechanisms that can make your effective rate look very different from the headline number.
| Plan Type | Reliant Offers | TXU Offers | Best For |
|---|---|---|---|
| Fixed Rate | check_small Yes - Basic Power |
check_small Yes - Simple Rate 12 |
Predictable bills, budget-conscious households |
| Bill Credit | check_small Yes - Power Savings |
Partial | Homes consistently at 1,000-2,000 kWh/month |
| Tiered Rate | check_small Yes - Conservation |
check_small Yes - Clear Deal, Saver's |
Conservation plans reward low-usage customers |
| Month-to-Month | No | check_small Yes - Flex Forward |
Renters, those expecting to move |
| Time-of-Use / Free Nights | Yes (limited) | check_small Yes - Free Nights & Solar Days |
EV owners, flexible usage households |
| Green / Solar Plans | Partial | check_small Yes - Solar Value 12 - 100% green |
Environmentally conscious customers |
Safe-Rate Score: Texas Electricity Ratings assigns each plan a Safe-Rate score (out of 10) measuring how closely the advertised rate matches what you'll actually pay. Reliant's Power Savings 24 scores 5.5/10 (Average). TXU's Clear Deal 12 scores 3.3/10 (Low) - meaning TXU's plan shows significantly more billing volatility across different usage levels.
Customer Reviews & Satisfaction
Neither company earns strong marks from customers - both hold a Bronze rating from Texas Electricity Ratings, and both score below 2.0 out of 5. However, context matters: as the two largest electricity retailers in Texas, they naturally attract the highest volume of complaints, and Texas Electricity Ratings adjusts its overall rankings to account for this scale effect.
Large providers proportionally receive more negative reviews because a single operational decision - say, a disconnect for non-payment - affects more customers at scale. Texas Electricity Ratings adjusts for this in its editorial rankings while leaving raw customer reviews intact.
Fees & Contract Terms
One of the most overlooked cost differences between these two providers is TXU's $9.95 monthly recurring charge (MRC). On an annual basis, that's nearly $120 added to your electricity costs regardless of usage - a charge Reliant avoids on most of its plans.
| Fee / Term | Reliant Energy | TXU Energy |
|---|---|---|
| Monthly Recurring Charge |
check_small $0 on most plans $9.99 on Basic Power if under 1,000 kWh |
$9.95 on most plans Adds ~$120/year to your total cost |
| Early Termination Fee (12-mo) | $150 | $150 |
| Early Termination Fee (24-mo) | $295 | $295 |
| ETF if Moving | check_small Waived |

Our Verdict
For most Texas households - especially average-sized homes consistently using 1,000 kWh or more per month - Reliant Energy is the better choice between these two providers. Its rates are lower, its bills are more predictable, and it avoids the flat $9.95 monthly fee that TXU tacks onto nearly every plan. At 1,000 kWh in Houston, Reliant's average monthly bill is $152 versus TXU's $197 - a $45 monthly difference that adds up to roughly $540 per year.
That said, TXU earns a genuine edge in specific situations. If you drive an electric vehicle and want to charge overnight, TXU's Free Nights & Solar Days plan is a strong fit. If you have solar panels on your roof, TXU offers purpose-built solar plans that Reliant doesn't match. And if you need the flexibility of a month-to-month contract with no cancellation penalty, only TXU offers that option.
The bigger picture: both companies are premium-priced brands charging roughly 20% above the Texas market average. If your primary goal is the lowest possible electricity bill, you'll likely find better value with providers like 4Change Energy, Champion Energy, or Gexa - none of which carry the marketing overhead of these two household names.
