TXU Energy Rates: What Each Plan Costs at Your Usage

TXU is a retailer. It buys power and sells it to you, but the wires belong to Oncor or CenterPoint, whose charges are set by the state and passed through at cost. So TXU has no tariff to look up. Each plan’s official price is its Electricity Facts Label, and every label quotes three averages at 500, 1,000 and 2,000 kWh. For a plan with bill credits or free hours, those three numbers can hide a $100 difference a month either side of them.

We read all 20 labels: ten plans, each in both delivery areas. Then we rebuilt every printed average from the charges on the label. All 66 matched to the tenth of a cent, so the same arithmetic prices any usage in between.

GreenCalculus sells no electricity plans and earns no commission on enrollments. TXU did not pay for or review this page.

Rank the plans at your usage

Put in the kWh from your last bill and its month. The table re-sorts TXU’s plans from cheapest to dearest for that one bill, with the reason each one lands where it does. Bill-credit and seasonal plans move around a lot from month to month, so try a summer bill and a winter one. Already with TXU, or with anyone else? Type the energy charge and base charge from your own label and your plan joins the ranking.

What a TXU price is made of

Simple Rate 12 in the Oncor area is a $92.95 TXU charge at 1,000 kWh (a $9.95 base charge plus 8.3¢ a kWh) and $72.73 for delivery ($4.06 a month plus 6.8673¢ a kWh). Delivery is 44% of that bill before taxes. Oncor and CenterPoint charge every retailer’s customers the same, and TXU’s labels say the charge is passed through as billed. The PUCT’s delivery table was last dated 1 November 2026 when this page was built. Oncor and CenterPoint can change them during the year, and the prices on this page follow the table.

TXU also sells in the AEP Texas, TNMP and Lubbock areas. We read the Oncor and CenterPoint labels only. Elsewhere, the one TXU plan on the state list, Free Nights & Cool Summer 12, shows how much the area matters. On 12 November 2026, at 1,000 kWh, it ran from 16.8¢ in Lubbock to 18.9¢ on TNMP’s wires.

Simple Rate against the state list

Texas publishes a list of plans that any retailer can post to, Power to Choose. To compare like with like, we kept the fixed-price 12-month plans with no free hours, no bill credits and no minimum-use fees. Those are the same terms as Simple Rate 12. TXU doesn’t list Simple Rate there; it sells that plan on its own website, so we priced it from its label.

In the Oncor area, 34 of the 34 comparable plans on the list on 12 November 2026 cost less at 1,000 kWh than TXU’s 16.6¢. The middle one was 13.0¢, which on 1,000 kWh is $36 a month less than Simple Rate. The cheapest was 11.9¢.

The list price is not the only thing that differs. On the state’s complaint scorecard for 1 April 2026 to 30 September 2026, TXU has 5 of 5 circles, the lowest-complaint band; 9 of the 42 retailers rated are in it. Some households choose to pay more for a large, familiar retailer. Whether that is worth $36 a month is your call.

Bill credits and the 1,000 kWh cliff

Three TXU plans give a fixed dollar credit once your usage reaches a set level. Smart 1000 Select 12 takes $100 off a bill of 1,000 kWh or more, and another $25 in July, August and September. That is why its label shows 9.9¢ at 1,000 kWh, the lowest of any TXU plan, and 22¢ at 500 kWh. In an October bill in the Oncor area, 999 kWh costs $205 and 1,000 kWh costs $106. At 900 kWh the average is 20.7¢.

Smart 2000 Select 12 has the same kind of drop at 2,000 kWh, where its label gives 10.5¢; at 1,000 kWh it is 16.9¢. Saver’s Choice 12 combines a $50 credit at 1,200 kWh with a cheap energy band from 1,201 to 2,000 kWh, which takes it from 18.1¢ at 1,000 kWh to 12.9¢ at 2,000. e-Saver 12 charges less for every kWh above 1,000 and takes 0.8¢ off each kWh if you pay by AutoPay. It is sold online only. These plans reward a home that stays above the threshold every month. A Texas house that uses 2,200 kWh in August and 800 in March gets the credit in one bill and not the other, so price a high month and a low month before you choose.

Free Nights: the break-even

Free Nights & Cool Summer 12 charges nothing for energy used from 9pm to 4:59am. In July, August and September it also takes 25% off the energy you use at night, capped at your daytime energy charges. The catch is the daytime price. Its energy charge is 18.4¢ a kWh, against 8.3¢ on Simple Rate 12, so the free hours have to cover the gap.

In the Oncor area, Free Nights costs less than Simple Rate only when more than 55% of your electricity is used between 9pm and 5am, or 44% in the three summer months. TXU’s own label works out its averages for a customer who uses 41% at night. At that share, the label’s 1,000 kWh price is 18.5¢, which is $19 a month more than Simple Rate. Smart Meter Texas, the state’s meter data site at smartmetertexas.com, records your usage in 15-minute steps, so you can find your own share before you sign. This plan is not open to homes with an electric vehicle, battery or solar panels.

Ultimate Season Pass 12 works the same way, by season instead of by hour. It takes 50% off energy in January, February, July and August, and 25% off in March, June, September and December, from an energy charge of 14.7¢. Spread over TXU’s average usage pattern, that is about 10.4¢ a kWh, still more than Simple Rate’s 8.3¢. The label puts it at 18.6¢ at 1,000 kWh.

Why TXU quotes 2,000 kWh

TXU’s plan pages quote every price at 2,000 kWh a month. That is nearly twice what its customers use. Federal data puts the average TXU home at 1,089 kWh a month in 2025. Every plan on this page has a fixed monthly charge, so it looks cheaper per kWh at 2,000 than at 1,000, and the credit plans look cheapest of all. Simple Rate 12 is 15.9¢ at 2,000 kWh, 16.6¢ at 1,000 and 18.0¢ at 500. At the average TXU home’s 1,089 kWh it is 16.5¢. Compare plans at your own number.

Variable plans: TXU’s price record

Flex Forward and the other Flex plans have no fixed term and no fee to leave, but their price can change every month. TXU publishes a record of each one’s average price for the last 12 months for Oncor and CenterPoint. It lists 23 plans in the Oncor area. Of the 18 with a full 12 months, 16 cost more in the latest month than in the first.

TXU states the usage behind each figure, usually 2,000 kWh and for a few plans 1,000, and the table gives it where TXU does. One thing we could not reconcile. TXU’s record puts Flex Forward at 20.6¢ in November 2026, but the label it offered new Oncor customers on 12 November 2026 gives 18.9¢ at the same 2,000 kWh. TXU doesn’t explain the gap. If you are already on Flex Forward, check the label that came with your last price change, not today’s sign-up label.

When a contract ends

From TXU’s Terms of Service, read with Texas rule §25.475:

• Last thirdTXU sends three expiry notices on a fixed-rate plan, spread through the last third of the contract.
• 30 days outThe final notice arrives at least 30 days before the end date on any contract longer than four months (15 days on four months or less). It includes the label for the plan you will move to if you do nothing.
• 14 days outFrom 14 days before the end date you can cancel without the early cancellation fee.
• End dateDo nothing and service carries on under “a TXU Energy default month-to-month renewal product”. The Terms of Service do not name it; its label comes with the final notice.
• After thatA month-to-month product carries no fee to leave, and its price can change from one month to the next. Put the price on that label into the tool above and compare.

Fees and leaving early

The 12-month plans charge $150 to leave early, Simple Value 24 charges $295, and the two Flex plans charge nothing. TXU waives the fee if you move and show proof of the new address, or if you cancel within 14 days of a notice that it is changing your terms. It also waives it in the last 14 days of the contract.

TXU’s Terms of Service list these fees. The labels’ average prices leave them out.

Taxes on the bill

Every price on this page is before taxes, because the tax depends on where you live. TXU’s labels say each bill also carries all taxes, including sales tax, and a reimbursement for the state’s miscellaneous gross receipts tax. The Texas Comptroller sets that tax by the population of the city you live in: 0.581% for a city of more than 1,000 but fewer than 2,500 people, 1.07% from 2,500 to 9,999, and 1.997% for 10,000 or more. The tax applies only in incorporated cities and towns of more than 1,000 people. Some cities also charge a municipal fee, which the labels leave out.

What TXU homes paid

The US Energy Information Administration counted 1,442,516 TXU homes in 2025, second only to Reliant among Texas retailers. Together they paid an average of 19.36¢ per kWh, or $210.70 a month on 1,089 kWh; the year before it was 18.70¢. Reliant’s homes averaged 18.38¢. These are revenue divided by kWh sold, over every TXU contract in force that year, old and new, fixed and variable, in every area and in every month including the summer.

That average sits well above today’s Simple Rate offer. Public data does not split the difference between customers on older contracts, those on month-to-month renewals and those on today’s plans, so we do not guess at it. For a quick check, divide your bill’s total before taxes by its kWh. If that comes to much more than 16.6¢ at around 1,000 kWh, look at what your contract has rolled into, and put its charges into the ranker at the top of this page.

Prices since 2002

Federal data reports Texas retailers once a year, so TXU has no monthly series. It starts in 2002, the first year of retail choice in Texas, when TXU served 2,295,629 homes at an average 8.29¢.

Renewable share and carbon

Most TXU plans list 3% renewable content, against a statewide average of 37% printed on the same labels. Solar Buyback System Flex lists 100%. Whichever you pick, the electrons reaching your meter come off the same ERCOT grid. Using the EPA eGRID ERCOT average, a 1,000 kWh month is responsible for roughly 334 kg of CO₂e, and that location-based figure is the same on a 3% plan as on a 100% one. The renewable share decides who gets credit for clean generation, not what the grid emits.

Solar Buyback System Flex is for homes with panels. It pays its energy charge back for every kWh you export, up to that month’s energy charges, and banks the rest, up to $1,000. Its label assumes 580 kWh exported a month, which is how it shows 9.3¢ at 500 kWh. Put your own export into the tool.

How we checked it

On 12 November 2026 we downloaded the Electricity Facts Label for each of the ten plans TXU’s website offered a home in the Oncor and CenterPoint areas, along with its Terms of Service and the two price-history pages. A script reads every charge, credit, discount and free-hour share from each label. It adds the delivery charges in the PUCT table and rebuilds the label’s own 500, 1,000 and 2,000 kWh averages, plus e-Saver’s AutoPay row. It stops if any of the 66 numbers is off by a tenth of a cent. It also checks that the state list’s prices for Free Nights match TXU’s labels, and that the PUCT table’s own sample bills add up.

To match the printed prices, a label counts July-to-September credits as a quarter of their value and uses TXU’s average night and seasonal shares. The calculator instead prices one real month: a summer credit counts in full in July to September and not at all otherwise, and you set your own night share. Delivery charges update from the state’s table each day. TXU’s own charges stay as read on 12 November 2026 until we read new labels, which we do each month. TXU’s website refuses our automated downloads, so we read them by hand. The comparison with other retailers uses the state list at 1,000 kWh only. The 2025 average is revenue from homes divided by kWh sold, from Form EIA-861.
