Key Takeaways

A useful Texas electricity rates comparison starts with your own usage and your own bill. The advertised rate is only one line in a much larger price story.

• Read the Electricity Facts Label before you choose a plan.
• Compare plans at the usage your home actually records.
• Check bill credits, usage tiers, fees, and the TDU charge.
• Treat a very low headline rate as a starting point, not an answer.
• Rank plans by total cost and contract fit, not search position.

How Texas Electricity Rates Actually Work

Most Texas comparison pages show a rate first and the bill details later. That order can make a plan look cheaper than it is for your home. A real Texas electricity rates comparison starts with the market, the delivery charge, and the way your retail plan sets its price. Your ZIP code matters because available plans and delivery charges depend on where you live.

Why your area is deregulated in the first place

Deregulation lets some households choose the company that supplies their electricity. The wires and local delivery still belong to a utility, but the retail plan can come from a different company. You are choosing a pricing contract, not a new set of poles and wires.

Texas is a useful example because power demand in ERCOT reached a record high in the first nine months of 2025, according to the U.S. Energy Information Administration, which manages about 90% of the state’s load. That demand can affect market conditions, but it does not tell you what a particular plan will cost at your address.

What the TDU charge is and why it is on every bill

The transmission and distribution utility, often shortened to TDU, maintains the local wires and delivers electricity to your home. Its delivery charges appear on your bill even when you choose a different retail electricity plan. They are separate from the energy charge shown in many advertisements.

Look for a line that changes with usage and another charge that may be fixed for the billing period. The exact amount depends on your service area and the current approved tariff. A plan with a low energy rate can still produce a higher bill if its other charges and credits do not fit your usage.

Who sets the price you really pay

Your retail electricity plan sets the energy price, rules, and contract terms. The TDU sets delivery charges under the rules for that service area. Your final bill combines both parts, along with taxes and any plan fees.

That is why a cents-per-kWh headline cannot settle the question. A household that uses little power can experience a different average price from a household that uses a lot, even on the same plan. The bill is the evidence you need.

The Ad Rate vs Your Real Rate

A low advertised rate is often tied to one usage level or one special condition. It may include a bill credit that disappears outside a narrow range. It may also leave out the effect of a base charge or delivery fee in the most visible part of the ad. You need to test the plan against your own monthly pattern.

Why the cents-per-kWh headline lies

The headline rate is usually an average at a stated usage level. It is not always the amount you pay for every unit of electricity. Some plans have a fixed charge, a minimum-use rule, or a credit that changes the average.

Read the plan’s Electricity Facts Label, or EFL, beside the advertised rate. The EFL shows how the average price changes at different usage levels. The real rate follows your usage, not the largest number on the card.

Bill credits, usage tiers, and the 999 kWh trap

Bill credits can make a plan look excellent at one usage level and poor at another. A credit may apply only when you use more than a stated amount, or it may end when your usage rises above a range. That creates a cliff near the edge of the tier.

If your home often lands just below or above the credit range, model both months. Do not assume that a small change in usage will create a small change in cost. A plan that depends on a credit needs a close look at your actual bills.

Teaser rates that double after month three

Some plans look attractive because the opening rate is temporary. The contract may later move to a variable rate, or a month-to-month rate may apply after the fixed term ends. Your renewal notice and the EFL matter more than the first search result.

Use the Teaser Test before you enroll. Find the rate after the promotional period, check when it can change, and see whether the plan becomes month to month after the contract. A low first bill does not describe the whole contract.

Read the EFL Like a Receipt

The EFL is the closest thing you have to a price receipt before you enroll. It gives you the plan’s energy charge, delivery assumptions, contract term, and key conditions in one place. Read it at the usage level that matches your home, then check the fine print around credits and fees.

Where to find the average price per kWh at YOUR usage

Look for the section that lists average price per kilowatt-hour at several monthly usage levels. Match that row to a recent bill, then repeat the check for a low month and a high month. This gives you a range instead of a single guess.

A calculator can help you compare the rows, but the EFL remains the source document. The Internal Revenue Service and other public agencies publish energy information for their own subjects, but neither replaces the plan’s EFL for your retail contract. For market context, the U.S. Department of Energy also publishes public energy material, not a price promise for your address.

The five fees that turn a cheap plan into an expensive one

Do not stop after finding the average rate. Scan the EFL and terms for the charges that can change your total bill. The useful check is simple and repeatable.

1. A monthly base charge.
2. A minimum-use fee.
3. A delivery charge or pass-through adjustment.
4. A bill-credit condition.
5. An early termination fee.

These items do not all apply in the same way to every plan. The point is to find which ones apply to the plan in front of you. Then put them into the same comparison as the energy charge, rather than treating them as footnotes.

Find Your Real Annual Cost in Three Steps

You do not need a perfect forecast to compare plans. You need a clean record of what your home used and a consistent way to test each contract. A year of bills usually shows the seasonal shape better than one average month.

Step one: pull 12 months of usage from your bill

Write down the kilowatt-hours for each month, not only the dollar total. Mark the months when air conditioning, heating, guests, or a move changed your routine. If you have fewer than twelve bills, use every bill you have and label the missing months.

Your usage pattern is more useful than a generic household estimate. A home that uses little power most of the year but spikes in summer should not be compared only at its annual average.

Step two: compare every plan at that exact kWh

Enter each month’s usage into the plan details when the tool allows it. If a plan only shows a few usage rows, use the nearest rows and inspect the EFL for the formula. Test the credit threshold instead of assuming it will apply.

ChooseMyPower’s plan comparison tool shows a live plan table from partner plan data, accepts a ZIP code, and lets you view plans at different usage levels. You can see available plans when you are ready to test your own address. The useful comparison is the one that uses your number, not a default number chosen for an advertisement.

Step three: rank by total dollar cost, not by rate

Add the estimated energy charge, delivery charge, base fee, and any other listed cost for each month. Then compare the contract term, price-change rules, and early termination fee. A plan with a slightly higher rate may fit better if it has fewer conditions, while a credit-heavy plan may be difficult to predict.

The Real-Bill Ranking is a method, not a promise about one provider. It puts your bill at the top of the comparison. The result should be easy to explain: this plan ranks here because of this usage pattern and these contract terms.

Best Plan Types for Common Usage Shapes

There is no single plan shape that fits every home. A small apartment, a large house, and a home with heavy summer cooling can land in different parts of the same EFL. Start with your usage shape, then decide how much price certainty you want.

Low usage (under 1000 kWh a month)

Low-use homes feel fixed charges more because those charges are spread over fewer kilowatt-hours. A bill credit that begins at a higher usage tier may not help you. Check the low-usage rows in the EFL before you react to a rate shown at a higher tier.

A simple fixed plan can be easier to compare, but simplicity is not the same as a lower total cost. Check the base charge, minimum-use rule, and delivery charge together. ChooseMyPower can show plans at several usage levels so you can see whether a headline rate holds at your actual use.

Average usage (1000 to 1500 kWh)

This range often sits near the usage level used in advertisements. That makes the headline more useful, but it still does not answer every question. Your bill can move into a different credit tier during hot or cold weather.

Compare a normal month with a higher month. Then read the price-change section and contract term. If the plan only looks good at one exact usage level, treat that as a warning to investigate rather than a reason to enroll.

High usage (over 1500 kWh, summer AC homes)

High-use homes need to watch both the energy rate and the size of seasonal changes. A small difference in the per-kWh charge can matter more when usage rises. A credit can also work differently once you cross a tier.

Use your highest recent bills in the comparison. Check whether the advertised rate is still shown at that level, and read the EFL for any cap or change in the formula. The U.S. Energy Information Administration Short-Term Energy Outlook provides broad energy market forecasts, but your own usage and contract still control your household comparison.

Spot a Commission-Driven Ranking

Search order is not proof of price. A plan may appear first because of advertising, placement, or a sorting rule that does not match your home. You can spot the difference by asking what number the page uses and whether it shows the assumptions behind the order.

How provider bidding shapes search order on most sites

Some comparison pages place sponsored plans near the top. Others sort by a sample rate at one usage level. Neither method tells you whether the plan fits your bill. A page can show a low rate while hiding the conditions that produce it.

Look for a clear usage selector, the EFL, and the charges behind the displayed average. If the page will not show those details, its order is a marketing signal rather than a full comparison. The question is not who is first. It is why.

What a bill-first ranking looks like instead

A bill-first page starts with your ZIP code and usage. It shows the assumptions used to estimate the price. It also lets you compare term, plan type, and other conditions without pretending that one rate fits every home.

ChooseMyPower’s comparison tool is built to show plans ranked by real price at your usage. The working idea is stated plainly: Ranked by your bill, not our commission. You should be able to change the usage and see why the order changes.

When to Lock In and When to Switch

Timing matters, but urgency is not a reason to skip the EFL. Your current contract may have a fixed end date, a notice period, or an early termination fee. Start by checking those terms and the price you will pay after the fixed period ends.

Seasonal rate patterns in Texas

Texas homes often use more electricity during very hot periods because cooling runs longer. The U.S. Energy Information Administration, Today in Energy reported that ERCOT electricity demand rose 5% from January through September 2025 compared with the same period in 2024, reaching 372 terawatt-hours in that period. That market figure gives context, but it does not predict your bill.

Your own bills show the pattern that matters for a plan decision. Compare a mild month with a high-use month before you choose a contract. If a plan depends on a narrow credit tier, seasonal movement can change the result.

Contract length, early termination fees, and timing your move

A longer contract can provide a longer period under the same stated terms. A shorter contract may give you more flexibility, but it can also end sooner and expose you to a new rate. Read the early termination rule and the moving exception, if one is listed.

Start comparing before your contract ends so you have time to read the EFL. If you are moving, check whether the fee changes when you leave the service address. The right time to switch is the point when you understand both the new bill and the cost of leaving the old contract.

Choose From Your Bill

A strong Texas electricity rates comparison does not begin with the lowest number on a page. It begins with your usage record, then checks the EFL, delivery charges, credits, fees, and contract terms. Put those pieces together and you can see which plan fits the way your home actually uses power.

Frequently Asked Questions

What is the most important number when comparing Texas electricity plans?

Use the average price at your actual monthly usage, then check the total bill after fees, delivery charges, and credits. The advertised rate alone is not enough.

Why can two homes pay different rates on the same plan?

The homes may use different amounts of electricity. A bill credit, fixed fee, or usage tier can change the average price at each level.

What does TDU mean on an electricity bill?

TDU means transmission and distribution utility. It refers to the local company that maintains the wires and delivers electricity to your home. Its charges are separate from the retail energy charge.

How do you read an Electricity Facts Label?

Find the average price per kilowatt-hour at several usage levels. Then check the base charge, delivery charge, credit rules, contract term, price-change rules, and early termination fee.

Is a fixed-rate plan always cheaper?

No. A fixed-rate plan sets the contract’s pricing terms for its stated period, but the total cost still depends on usage, fees, delivery charges, and credits. Compare the full EFL.

When should you compare a new electricity plan?

Start before your current contract ends. This gives you time to review the EFL and check whether an early termination fee or move affects your choices.

Why should you compare plans at more than one usage level?

Your usage changes through the year. Testing a low month, a normal month, and a high month shows whether the plan stays reasonable or depends on one narrow credit tier.

Check Your ZIP Code

When you have your recent usage ready, put your ZIP code into the plan comparison tool and review the available plans at your real usage. Use the EFL and your bill to decide what deserves a closer look.
