Why Texas Ad Electric Rates Differ From Your Real Bill

You finally found a plan advertised at 9.8¢ per kilowatt-hour—and your bill still feels expensive. That gap is normal, and it is not usually a bait-and-switch. Ads, comparison sites, and even state-mandated labels compress a messy monthly invoice into one friendly number. Your real bill adds regulated delivery charges, flat monthly fees, usage rules, taxes, and sometimes price changes the ad never promised to hold still.

If you shop in Texas—or in other choice states like Ohio and Maryland—the trick is knowing what that advertised ¢/kWh actually includes, what it assumes about your usage, and what still lands on your bill separately.

The Advertised Rate Is a Label, Not Your Bill

When you shop for power online, you are almost always looking at a normalized price: cents per kilowatt-hour (kWh), often labeled an average or energy charge. That format helps you compare dozens of plans side by side. It is also nothing like the total amount due on your statement.

A kilowatt-hour is simply how utilities meter consumption—the amount of power you used over time. Your bill multiplies usage (kWh) by rates and then adds fees that may not be per-kWh at all. The ¹ requires easy-to-read bills for most customers, but each retail electric provider still designs its own layout and decides how much to itemize.

Nationally, the U.S. Energy Information Administration (EIA) explains that retail electricity prices reflect far more than a generator’s fuel cost. Prices cover building and maintaining power plants and the grid, and in some areas include returns for utility owners. Key drivers include fuels, power-plant costs, transmission and distribution systems, weather, and whether regulators set prices or markets do. In 2025, the U.S. annual average retail price was about 13.63¢/kWh, with residential customers paying about 17.30¢/kWh on average—higher than commercial or industrial classes because delivering smaller volumes to homes costs more per unit. Those statewide or national averages still will not match your house in July.

Comparison tools exist to shrink complexity. ¹, the PUCT’s official electric-choice site, posts certified retail plans and tells shoppers to use each plan’s Electricity Facts Label (EFL) for standardized pricing, fees, and contract terms. Third-party sites—including brokers like ², which markets comparisons across Texas, Ohio, and Maryland—also emphasize “real rates” rather than teaser pricing. Even when the tool is careful, the headline ¢/kWh is still an estimate, not a guarantee of your bottom line.

Texas Splits the Bill: Retail Supplier vs. TDU

Texas restructured most of its retail electric market in 1999, allowing many consumers to pick a Retail Electric Provider (REP) while the physical grid stayed put. The REP sells you the energy; the Transmission and Distribution Utility (TDU)—your local wires company—still delivers it, reads the meter, and maintains poles and lines. If the power goes out, you call the TDU, not the company whose logo is on the supply line item.

That split is why a single “9.8¢” ad can still produce a higher bill:

  • Supply charges come from the REP you selected (the competitive part).
  • Delivery charges are regulated TDU fees passed through on your bill.
  • Taxes and miscellaneous assessments apply on top.

¹ is explicit: reliability does not change when you switch REPs, because the same regulated wires company serves your address. The TDU portion is not something you negotiate on a promo landing page.

On a fixed-rate plan, your contracted energy price per kWh generally will not move for the contract term except for certain pass-throughs. The ³ notes that fixed-rate contracts may still change for Transmission and Distribution (TDU) fee changes, ERCOT or Texas Regional Entity administrative fees, or new federal, state, or local laws imposing costs beyond the REP’s control. So even a “locked” supply rate can shift when regulated wires charges adjust.

If you are not in a deregulated area—some municipalities, cooperatives, and investor-owned territories—¹. You would then buy bundled service from a single utility with a different bill format, but you will still see delivery and energy components in the underlying cost stack.

Reading the Electricity Facts Label (EFL)

Texas REPs must provide an Electricity Facts Label for every plan. Think of it as the nutrition label for electricity: contract type, term, renewable percentage, fees, and pricing presented in a standard format so you can compare offers ³.

The EFL is also where many advertised averages come from. For time-of-use plans, the glossary explains that average price calculations on the EFL and on Power to Choose use each REP’s estimate of how much energy you consume during free or discounted hours versus premium hours. Your real average price depends on whether your habits match that estimate. Shift usage into discounted windows and the plan can shine; ignore the pattern and the same plan can raise your bill.

¹ requires REPs to supply a Terms of Service (TOS) contract, a Your Rights as a Customer disclosure, and advance contract-expiration notices for longer agreements. Those documents matter when the ad is silent on early termination fees, renewal rules, or what happens when a contract ends (including automatic rollover to a month-to-month variable rate if you do nothing).

Ads rarely show the full EFL. They show the yield: one average ¢/kWh at 500, 1,000, or 2,000 kWh. That is useful math, but it is still someone else’s usage story.

Usage Assumptions That Move the Average

This is the number-one reason a great ad meets a mediocre bill: the ad assumes a kWh tier you did not hit.

Many Texas plans trigger fees at low usage. ¹ warns that some contracts charge extra if you use less than 500 or 1,000 kWh in a billing period—often called a minimum usage fee. The glossary adds that this fee may not appear as its own line; you might only catch it on the EFL. Conversely, some companies credit or waive other fees when you exceed a threshold.

Seasonality matters too. EIA notes that prices are usually highest in summer when demand peaks and more expensive generation runs. A plan priced using a spring kWh assumption can look different in August when air conditioning drives usage up—or down in a mild month, triggering a minimum fee.

Time-of-use plans add another layer: the average on the label assumes a split between cheap and expensive hours. Work-from-home daytime AC or overnight EV charging can help or hurt versus that assumption.

Indexed (market-linked) plans tie your rate to a public index. The glossary explains rates can move substantially month to month, with benefits and risks similar to variable plans. An ad captured on a low-index month is not the bill you get after a hot week and a price spike.

Finally, remember class effects. EIA reports residential retail prices are usually the highest among major customer types because distribution to homes is less efficient per kWh than serving large commercial or industrial accounts. Your apartment at 600 kWh and your neighbor’s house at 2,400 kWh are not going to see the same effective ¢/kWh even on “the same” plan tier.

Fees and Line Items Ads Leave Out

Even when the energy rate is honest, the invoice stacks dollars the banner omitted:

  • Base charge / monthly fee: A flat amount each month regardless of kWh, defined in the ³ as a charge applied whether or not you used power.
  • Minimum usage fee: Triggered when consumption falls below plan thresholds, as described in the ¹.
  • TDU delivery charges: Regulated wires costs passed through—explicitly called out as a reason fixed supply rates can still move on the ³.
  • Administrative pass-throughs: ERCOT or Texas Regional Entity fees on some contracts.
  • Taxes and government assessments: Not part of the REP energy charge but part of what you pay.

¹ also notes that itemization is up to each company—some bills bundle charges, others break them out. A low supply rate buried inside a busy bill can be hard to spot without the EFL in hand.

Illegal practices show up as surprises too: slamming (switching you without consent) and cramming (adding unauthorized charges) are prohibited, with enforcement through the PUCT consumer hotline. Those are not normal pricing gaps, but they are why you should read every line when the total looks wrong.

Plan Types: Fixed, Variable, Indexed, and Time-of-Use

Contract design changes what “9.8¢” means over time:

Fixed-rate plans lock the energy price per kWh for the contract term, with the pass-through exceptions noted above. Budgeting is simpler; you may miss market dips until you can switch at renewal.

Variable-rate plans can change monthly at the REP’s discretion, reflecting market conditions. The ³ highlights upside in falling markets and risk when prices spike. There is often no long-term contract, but there is also less price certainty.

Indexed rate plans move with a published index named in the contract. REPs must explain the formula and how they notify you of index changes. Treat advertised snapshots as point-in-time, not promises.

Time-of-use plans reward shifting load to nights or weekends—or punish you for not doing so. The label’s average price is only as good as your schedule.

Prepaid service bills differently altogether—pay-as-you-go with daily usage calculations on smart meters, per the ³—and may not look like a traditional postpaid bill at all.

None of these is inherently bad. They are just different products wearing similar ad clothing.

Outside Texas: Bundled Bills and Choice Markets

Not every state splits the bill the Texas way. EIA’s overview of describes how, depending on region, you might buy from a municipal utility, cooperative, investor-owned utility, or—in some states—a power marketer with the local utility delivering electrons. No matter who sells it, local utilities still run the distribution system that connects your meter to the grid.

In fully regulated states, supply and delivery may appear as one utility bill without a shopping step. In choice states (Ohio, Maryland, and others), you may pick a supplier while wires charges remain regulated—conceptually similar to Texas though rules and labels differ. The structural lesson carries: headline energy rates exclude regulated delivery and policy costs that EIA lists as core price drivers nationwide.

EIA also reminds readers that most consumers pay seasonal average rates, not the volatile wholesale prices that swing minute by minute. Ads echo that smoothing by showing one average ¢/kWh—even when the underlying market is twitchy.

A Practical Way to Compare Without Sticker Shock

Treat advertised rates as the start, not the finish:

  1. Pull your last 12 months of kWh from bills or Smart Meter Texas. Note summer peaks and winter lows.
  2. Open the EFL for any plan you like and rerun the math at 500, 1,000, and your actual kWh. Include the base charge and check for minimum usage fees at your low months.
  3. Add TDU delivery using the pass-through section of the EFL or your current bill’s wires pages—ads usually show supply averages, not full landed cost.
  4. Read the TOS for term length, early termination fees, renewal behavior, and pass-through clauses.
  5. Match plan type to behavior: stable households often prefer fixed; flexible switchers might accept variable; night-heavy users should explore time-of-use honestly.
  6. Use official tools first¹ for certified Texas offers—then broker sites if you want filtering help, verifying anything that looks too good against the EFL.

Bottom line: Texas ads sell a standardized average for a fictional month. Your real bill is supply + regulated delivery + fees + taxes, scaled by your usage and your contract mechanics. Compare with your kWh history in hand, and the gap between ad and invoice stops feeling like a surprise—and starts looking like math you can control.
