No-Contract & Month-to-Month Electricity in Texas: How Lone Star Flex Works

In Texas, you can use a month-to-month contract electricity plan, meaning for each billing cycle you can purchase electricity without committing to a long-term plan or paying termination fees. In return, you pay a variable rate instead of a fixed rate, meaning your rate can change monthly based on the ERCOT wholesale market. Ambit Energy's Lone Star Flex is a Texas month-to-month plan that offers this service: enroll today, cancel any month, and pay a rate that floats. This guide shows you how a month-to-month plan in Texas prices out, who Lone Star Flex is right for, and where variable-rate plans hurt you the most.

Key Takeaways

• A no contract electricity Texas plan is a variable-rate product: no term commitment, no early termination fee, and no ETF math to unwind if you cancel.
• Plans that are month-to-month are typically 10 to 20% more expensive than 12-month fixed plans, around 1.4 to 3.2 cents per kilowatt-hour more (Electric Rates, 2026).
• Lone Star Flex by Ambit Energy is a statewide Texas no-contract product that passes TDU delivery charges through at cost.
• Best suited for: renters, people who move often, people repairing their credit, and Texans between fixed contracts. Not a good fit: heavy AC users when variable rates spiked as high as $0.30 per kWh during the July 2026 heat dome (Electricity Plans, 2026).
• The Public Utility Commission of Texas (PUCT) logged 1,876 customer complaints against retail electric providers between September 2025 and February 2026, many tied to variable-rate bill shock (Electric Rates, 2026).

What is a no-contract month-to-month electricity plan in Texas?

A no-contract month-to-month electricity plan in Texas is a residential power plan sold by a retail electric provider (REP) with a one-month billing cycle that renews every month, no long-term contract, and no fees for early termination. Because there is no contract term, the REP sets energy prices at a variable rate. That means the cents-per-kilowatt-hour figure on your Electricity Facts Label (EFL) can move up or down every billing cycle. You keep the freedom to cancel or change your plan at any time without paying a cancellation fee.

Since Texas deregulated its residential electricity market in 2002, these plans have been available. Approximately 85% of Texas is inside the deregulated ERCOT market, where residents actively compare retail electric providers rather than being served by a single utility (Power Outage US, 2026). Month-to-month plans are listed alongside 12-month, 24-month, and 36-month fixed-rate plans on the Texas Power to Choose marketplace and on individual REP sites.

How does a variable rate on a Texas month to month electricity plan work?

On a Texas month to month electricity plan, a variable rate means the retail electric provider recalculates the per-kWh energy charge every month based on the ERCOT wholesale market, seasonal demand, and the provider's own margin. Your rate can change with each billing cycle, and unless the EFL specifies a cap (rare on flex products), there is no ceiling.

Where the price actually comes from

Your total per-kWh charge on any Texas retail plan, fixed or variable, has three stacked pieces:

1. ERCOT wholesale energy cost. The Electric Reliability Council of Texas (ERCOT) runs the wholesale market. Wholesale prices are projected to rise 45% in 2026 after climbing 21% in 2025 (Nuwatt Energy, 2026). Fixed-rate plans hedge that exposure ahead of time. Variable-rate plans do not.
2. TDU delivery charges. Your Transmission and Distribution Utility (Oncor, CenterPoint, AEP Texas Central, AEP Texas North, or Texas-New Mexico Power) charges every REP the same regulated rate to move power to your meter. Current Texas TDU volumetric charges run 3.2 to 4.1 cents per kWh, plus a $5.00 to $9.00 monthly base fee (Compare Power, 2026). Lone Star Flex and most Ambit Texas plans pass these through at cost, with no markup.
3. Retail margin. What your REP adds for customer service, billing, and profit. On a variable plan, this is the piece with the most room to move month to month.

For an anchor on the retail number, Choose Texas Power reports the average Texas residential rate at 15.97 cents per kWh on typical 1,096 kWh monthly usage, which works out to about $175 per month (Choose Texas Power, 2026). Residential rates in Texas run about 12.1% below the national average, based on U.S. Energy Information Administration (EIA) data, but on a variable plan that discount is not guaranteed month to month.

How often the rate can change

On a Texas variable-rate plan the REP has the right to change the energy charge with almost every bill. In practice, most Ambit brand and competitor variable plans reprice monthly. During calm weather months your rate may drift down or hold. During peak demand months (July, August, February cold snaps) it can jump significantly in a single cycle. That single-cycle change is the entire risk of a no-contract product.

How does Ambit's Lone Star Flex plan work?

Lone Star Flex is Ambit Energy's Texas month to month electricity plan: a no-contract, variable-rate residential product available across the deregulated ERCOT footprint (Oncor, CenterPoint, AEP Texas Central, AEP Texas North, and TNMP service areas). There is no term commitment, no early termination fee, and no penalty if you switch to a different Ambit plan later.

Here is how a Lone Star Flex bill is built each month:

• Energy charge: a per-kWh rate set by Ambit for that billing cycle, published on the current Electricity Facts Label (EFL) for your ZIP.
• TDU delivery charges: the Oncor, CenterPoint, AEP TX, or TNMP volumetric charge (3.2 to 4.1 cents per kWh) plus their monthly base fee ($5.00 to $9.00), passed through at cost.
• Ambit base charge or monthly service fee, if any: disclosed on the EFL.
• Taxes and PUCT fees: standard on every Texas retail bill.

Two features set Lone Star Flex apart from the generic marketplace variable plans:

1. Statewide TDU coverage. Because Ambit is authorized across all five Texas TDU service areas, the same plan follows you if you move within the deregulated zone. You do not have to re-shop when you cross from Oncor into CenterPoint.
2. No-contract, but a straight upgrade path. If you decide to lock in later (for example, before summer), you can move from Lone Star Flex to a fixed-rate Ambit plan like Lone Star Classic without paying an ETF, because there was no term to break.

For the current per-kWh Lone Star Flex rate in your ZIP code, always check the live EFL: Ambit Energy plans and EFLs. Rates change monthly and any figure quoted in an article is stale within one billing cycle.

Who should choose a Texas no-contract electricity plan?

A Texas no-contract electricity plan is the right choice when the value of flexibility (the ability to cancel or switch any month with no fee) is higher than the roughly 10 to 20% rate premium you pay for it. Concretely, that describes five household types:

1. Renters on a short or month-to-month lease. If your lease could end on 60 days notice, a 12-month fixed contract creates ETF risk you cannot control.
2. Anyone planning to move in the next 30 to 90 days. Even with the Texas move-out exemption on most fixed contracts, a no-contract plan removes the paperwork and the "prove the address change" step.
3. Shoppers between fixed contracts. If your 12-month plan just ended and you refuse to be rolled onto the REP's holdover variable rate (usually the most expensive tier), enrolling in Lone Star Flex parks you on a defined, transparent variable product while you shop.
4. Credit-repair or no-deposit shoppers. Some REPs waive the deposit on their month-to-month product but require one on the fixed plans. Confirm on the specific EFL.
5. New arrivals to Texas. If you just moved to Houston, Dallas, or Austin and cannot yet predict your monthly kWh usage, a month or two on a no-contract plan lets you see two real bills before committing to a 12-month or 24-month rate tier.

A Texas no-contract electricity plan is the wrong choice when you are a heavy summer AC user in a home you plan to keep, with stable income and no need for the flexibility. The math on 12 months of predictable fixed pricing almost always beats a variable rate for that household, especially given the 45% projected ERCOT wholesale increase in 2026 (Nuwatt Energy, 2026). For a broader picture of the choice, see our guide to fixed-rate vs variable-rate electricity in Texas.

What are the drawbacks of a month-to-month electricity plan in Texas?

The drawbacks of a Texas month-to-month electricity plan are rate volatility during peak events, difficulty budgeting, and a higher expected 12-month total cost than a comparable fixed plan. Three specific numbers make this concrete:

• Rate premium. Across the Texas market, variable and no-contract plans price about 10 to 20% above 12-month fixed rates, or roughly 1.4 to 3.2 cents per kWh more (Electric Rates, 2026). On a 1,096 kWh Texas average bill, that is $15 to $35 more per month in a normal month.
• Peak spikes. During the July 2026 heat-dome event, some Texas variable-rate customers were billed as high as $0.30 per kWh for a full cycle, roughly double the 15.97 cent state average (Electricity Plans, 2026). A single bad month can wipe out several months of savings on a variable plan.
• Complaint volume. The Public Utility Commission of Texas recorded 1,876 customer complaints against retail electric providers between September 2025 and February 2026, a period that included the winter cold snap. Many complaints tied back to variable-rate bill shock (Electric Rates, 2026).

If you cannot absorb a bill that doubles for one cycle, do not put yourself on a variable-rate product headed into a Texas summer.

Month-to-Month vs 12-Month Fixed vs 24-Month Fixed: side-by-side

How does Lone Star Flex compare to TXU Flex Rewards, Reliant Month-to-Month, and Chariot Freedom?

All four are variable-rate, no-contract Texas products, but they differ on rewards, TDU coverage, and renewable content:

If you value rewards and satisfaction guarantee framing, TXU Flex Rewards is the pitch. If you value 100% renewable content, Chariot Freedom is the pitch. If you value statewide TDU coverage plus a clean upgrade path into a fixed Ambit plan without switching REPs, Lone Star Flex is the pitch.

What happens to variable rates during ERCOT peak demand or a Texas heat wave?

During ERCOT peak demand or a Texas heat wave, variable-rate customers absorb the full wholesale price move in that billing cycle, while fixed-rate customers pay their locked rate no matter what the market does. The ERCOT wholesale price can swing from about $20 per megawatt-hour to as high as $5,000 per megawatt-hour, the market cap, in a matter of hours during a scarcity event (Elite Energy Consultants, citing ERCOT market data).

The July 2026 heat dome is the current textbook example. As ERCOT set new peak demand records above 83,000 MW and lost roughly 501 MW of generation on July 3, wholesale prices ran at scarcity levels for stretches of afternoon load hours (see our summary in how Texas summer bills stack up). Retail variable-rate plans repriced their July energy charge accordingly. Some Texas variable customers were billed at as much as $0.30 per kWh for the cycle (Electricity Plans, 2026). A Lone Star Classic (fixed) customer, by contract, paid their locked rate.

Do no-contract electricity plans require a deposit in Texas?

Whether a Texas no-contract electricity plan requires a deposit depends on the REP's credit policy, not the fact that the plan is month-to-month. Most Texas REPs run a soft credit check at enrollment. If your credit clears the REP's threshold, the deposit is waived. If it does not, the REP can request a deposit before turn-on. Some month-to-month products (for example, prepaid Pogo Energy) are specifically built for the no-deposit and no-credit-check use case, but they price at a premium versus a standard variable plan. Always confirm on the specific EFL for your ZIP code.

How to switch to a no-contract Texas electricity plan

Switching to a no-contract Texas electricity plan takes five steps and typically 24 to 72 hours:

1. Enter your ZIP code on your REP's site or the Power to Choose marketplace to confirm your TDU service area (Oncor, CenterPoint, AEP Texas Central, AEP Texas North, or TNMP).
2. Pull the Electricity Facts Label (EFL) for the plan. Read the variable rate history section and the base charge line. If a fixed plan looks cheaper for your usage tier, walk through our EFL walkthrough guide before you enroll.
3. Confirm there is no ETF and no auto-renewal into a fixed plan. A true no-contract product renews monthly at whatever the variable rate is; it does not silently shift you into a long-term fixed contract.
4. Enroll. For a standard switch, expect 24 to 72 hours before your new REP is your provider of record; for a same-day switch, expect a higher enrollment fee.
5. Set a monthly bill-review reminder. The whole value of a no-contract plan is that you can leave. Actually check the rate each cycle and compare it to current fixed offers so you can move when the math changes.

The Lone Star Flex Trade-Off Framework: is a no-contract Texas plan right for you?

The Lone Star Flex Trade-Off Framework is a five-factor decision tool for Texas shoppers weighing a no-contract plan against a fixed contract. Rate each factor as 0, 1, or 2, then add the scores. The higher your total, the better a month-to-month plan fits your situation.

1. T: Tenure at address. 0 = staying 2+ years. 1 = 6 to 24 months. 2 = under 6 months or unsure.
2. U: AC-heavy summer usage. 0 = large home, AC running hard, over 1,500 kWh/month in July. 1 = average Texas usage (about 1,096 kWh/month). 2 = apartment or low usage under 800 kWh/month.
3. E: Contract exit fee owed today. 0 = mid-contract, ETF over $200 owed if you switch to a fixed plan now. 1 = ETF under $100 or nearing contract end. 2 = no current contract, no ETF owed.
4. R: Rate-shopping bandwidth. 0 = "set it and forget it," never re-shops. 1 = re-shops once a year at renewal. 2 = will review the EFL every month and switch when it makes sense.
5. C: Credit / deposit status. 0 = clean credit, no deposit required anywhere. 1 = deposit required on some plans. 2 = deposit-waiver only on month-to-month.

Interpretation: score 8 to 10, a no-contract plan like Lone Star Flex is a strong fit. Score 5 to 7, it fits some months, but model a 12-month fixed side-by-side. Score 0 to 4, a fixed-rate plan is almost certainly cheaper for you across a full year.

How to leave a fixed-rate Texas electricity contract early

To leave a fixed-rate Texas electricity contract early, you either pay the Early Termination Fee (ETF) disclosed on your EFL or use the Texas move-out exemption. ETFs on Texas 12-month and 24-month fixed plans typically run $150 to $295 flat (Gatby, 2026), and some providers structure them as a per-month-remaining charge (about $20 per remaining month).

You can waive the ETF entirely under the Texas move-out exemption by providing the REP with proof of a change of address (a lease, deed, or utility bill at the new address) within the required window. That exemption is a statewide right, not a courtesy. Read your EFL for the exact documentation the REP requires. If you have a fixed contract and no move on the horizon, moving to a month-to-month plan usually means paying the ETF and eating that cost; run the math against expected savings before you switch.

Frequently asked questions about no-contract electricity in Texas

Is a month-to-month electricity plan cheaper in Texas?
No. On average, a month-to-month electricity plan is not cheaper in Texas. Variable and no-contract plans price about 10 to 20% above comparable 12-month fixed plans, or roughly 1.4 to 3.2 cents per kWh more (Electric Rates, 2026). You are paying for flexibility, not savings.

Do you need good credit for a no-contract electricity plan?
Not always. Many Texas REPs waive a deposit on month-to-month products even for shoppers with limited credit history, and prepaid REPs like Pogo Energy skip the credit check entirely. If you are turned down at one REP, the next one may accept you.

How often can Ambit change my Lone Star Flex rate?
Ambit can change the Lone Star Flex energy charge every billing cycle, and the current rate is disclosed on the live EFL for your ZIP code. That monthly repricing is the whole trade for the no-contract, no-ETF structure.

Can I move without paying a cancellation fee on a fixed plan?
Yes, under the Texas move-out exemption. Provide your REP with proof of address change (lease, deed, or new utility bill) and the ETF is waived. The exemption is a statewide consumer protection, but the paperwork requirements are set by the REP.

What is the best month to switch electricity in Texas?
The best months to switch electricity in Texas are typically March through May and September through October, when wholesale prices sit below summer and winter peaks and REPs promote fresh fixed-rate offers. Locking a 12-month plan in shoulder season protects you from the July and August bill shock that variable-rate customers absorb.

Can I lock into a fixed rate later if I start on Lone Star Flex?
Yes. Because Lone Star Flex has no term commitment, you can move from Lone Star Flex to a fixed-rate Ambit plan (for example, Lone Star Classic 12) at any time with no ETF. Many Texas households use Lone Star Flex as a bridge until they are ready to commit to a 12-month rate.

If you are in a deregulated ZIP code, the most important decision you will make regarding pricing electricity in Texas is choosing fixed or variable rates. That one decision drives whether your July bill is an average line item or a $600 surprise, whether you are locked in for two years, and whether a heat wave can quietly double your rate overnight. This guide walks you through both plan types and all the associated numbers. It also provides a five-question decision framework called the Texas Rate Reality Check so you can stop making guesses and pick the plan that best fits your needs.

The 60-Second Answer

For most Texas households, a fixed-rate electricity plan is the safer, cheaper long-term choice. Fixed rates protect you from ERCOT price swings by locking in your energy charge per kilowatt-hour for the whole contract. Prices in the wholesale market can jump from $20 to $5,000 per megawatt-hour in less than a few hours (Elite Energy Consultants, citing ERCOT market data). In milder months, variable rates can be cheaper, but you take on all the market risk yourself, and Texas has already had two large lessons about why that matters. The two lessons are Winter Storm Uri in February 2021 (a U.S. Energy Information Administration report states that average residential bills increased about 17 percent that month) and the August 2023 heat wave (Business Insider reported that prices spiked to $4,750 per megawatt-hour on August 18, a 6,000 percent increase). If you want to keep your bills predictable by staying for a year or more, fixed wins. If you want to know when variable makes sense, keep reading.

What Is a Fixed-Rate Electricity Plan in Texas?

In Texas, fixed electricity rate plans keep the energy charge on your Electricity Facts Label (EFL) at a constant rate per kilowatt-hour for the entire term of the contract, whether you choose six months, twelve months, twenty-four months, or thirty-six months. Some providers also offer 3-month and 6-month options.

Here are three things to consider when understanding how the lock actually works.

1. While the energy charge is locked in, other line items can still move. Your Transmission and Distribution Utility (TDU) delivery charge (Oncor, CenterPoint, AEP, or TNMP) can change when the Public Utility Commission of Texas approves a rate case. Ambit Energy and every other retail provider are required by law to pass these through. Your EFL documents ERCOT and regulatory fee changes. For a recent example, see Oncor Rate Increase 2026.
2. Not every "fixed" rate is truly fixed. Many "fixed" plans in Texas include bill-credit tiers, which means that if you go above or below a specified usage band (typically 1,000 or 2,000 kilowatt-hours per month), the effective rate can increase by 30 to 60 percent. Always read the EFL pricing table before signing a contract.
3. Fixed plans usually carry early termination fees (ETFs). For 12-month contracts, ETFs are usually about $150. For 24-month contracts, they can range from $175 to $250. Movers often qualify for an ETF waiver with proof of a new address outside the service area.

As of mid-2026, fixed-rate energy plans in the Oncor DFW area are roughly 7.3 to 16.6 cents per kilowatt-hour, while CenterPoint Houston plans are between 6.6 and 19.4 cents per kilowatt-hour, with the Texas statewide average around 13.5 cents per kilowatt-hour. Plan details and rates are subject to change; the Energy Facts Label available for each plan is the authoritative source. For a deeper breakdown of what drives your bill, see Electricity Prices per kWh: Top FAQs Answered.

What Is a Variable-Rate Electricity Plan in Texas?

Variable rate electricity Texas plans are month-to-month contracts. Each month, your energy price resets based on wholesale ERCOT prices, weather, and the retail provider's hedging costs. In this arrangement you have no contract, no ETF, and you can leave when you want, but you absorb the market risk yourself.

In Texas, variable rates typically sit between 11.9 and 14.1 cents per kilowatt-hour in calm months. However, that is a monthly snapshot, not a monthly promise. There are three things variable plans do not protect you from:

• Severe weather spikes. During Winter Storm Uri (February 2021), some Texas customers on wholesale-indexed variable plans received bills in the thousands of dollars for a single week. Standard variable plans are not the same as wholesale-indexed, but the same market forces influence both.
• Summer demand tightness. ERCOT spot prices hit $4,750 per megawatt-hour on August 18, 2023, a 6,000 percent increase compared to the daily average. ERCOT CEO Pablo Vegas told The Texan in October 2023 that there is no "silver bullet" for the state's summer grid stress and that reliability reforms were "in development."
• The provider's own hedging losses. Your retail provider buys electricity in the wholesale market. When their hedges lose money in a volatile month, that loss often gets passed to customers with variable plans first, because those are the customers whose rates can move.

In certain situations a variable plan can be beneficial, but for most Texas households the risk-adjusted math favors a fixed plan. See Texas TDU Delivery Charges June 2026 for a real example of what shows up on both plan types.

The Real Cost Gap: Fixed vs Variable in 2026

The numbers show this pattern. In a calm month with usage of 1,094 to 1,194 kilowatt-hours (roughly the Texas statewide residential average) at 12 cents per kilowatt-hour, the energy charge before TDU fees looks nearly identical on a fixed plan and a variable plan, about $131 to $143. In a spike month, the story changes. That same house would incur an energy charge of $218 to $239 if the variable plan resets to 20 cents per kilowatt-hour because ERCOT prices tightened. Any gap of $80 to $100 per month, multiplied by two or three summer months a year, is the risk premium you are pricing into your decision.

"Electricity demand is rising, and Texas is about to find out which energy technologies and policies can keep pace," Michael Webber, professor at the University of Texas Energy Institute, told Texas Energy and Power in March 2026. Rising demand does not benefit consumers on month-to-month power. It benefits the provider that can reset the rate.

The Texas Rate Reality Check: 5 Questions Before You Sign Up

The usual fixed-versus-variable conversation gets stuck on "fixed is stable, variable is flexible." That is true and not the most helpful comparison. Answer these five questions in order to find the plan that fits you best.

Question 1: How long will I live at this address?
If your answer is under six months (a summer sublet, a short-term relocation, a house sale in progress), a variable plan is a legitimate choice because you avoid the ETF risk. For anyone in the one year or longer category, a fixed plan almost always wins because you get to lock in today's rate for the whole horizon.

Question 2: What is my monthly kilowatt-hour usage?
Pull the last 12 months from your current bill or your provider's online portal. If your average is above 1,300 kilowatt-hours per month (which is the norm for the CenterPoint Houston area), your dollar exposure to a variable-rate spike is larger. High-use households benefit the most from fixed. Low-use households (under 800 kilowatt-hours) have less exposure and a little more room to experiment with a variable plan.

Question 3: What is my risk tolerance for one $600 bill month?
Be honest. If the thought of a $600 August bill would force you to move money from another line item in the family budget, a variable plan is not the plan for you. Fixed rate energy plans exist specifically to make that scenario impossible.

Question 4: Do I have 30-day flexibility to switch providers if the price moves?
Variable plans reward customers who actually check Power to Choose every month and jump when a better rate appears. If you will not check, you will not switch, and you will pay whatever the provider decides. Go with a fixed plan and revisit at renewal.

Question 5: Am I inside the ERCOT deregulated grid or a municipal utility (MOU)?
About 85 percent of Texans live inside the deregulated ERCOT market and can shop rates freely. If your ZIP code is served by a municipal utility like Austin Energy, CPS Energy in San Antonio, or a cooperative, the fixed-versus-variable choice does not apply the same way and Ambit Energy cannot offer you a plan in that territory.

Score your five answers. If four or five point to fixed, that is your answer. If three or more point to variable, run the numbers on a specific plan before signing anything. Compare full plan structures in Texas Electricity Plans Explained.

When a Variable Plan Actually Makes Sense

There are only three scenarios in which choosing a variable rate electricity Texas plan is a good idea:

• You are between long-term plans. Your fixed contract ended, you are moving in the next 60 to 90 days, and you want to avoid an ETF. A variable plan gives you a graceful exit.
• You expect wholesale prices to fall. This is uncommon and usually requires checking the ERCOT dashboard on a weekly basis, but it can occur during mild spring months when solar and wind generation is high and demand is low.
• You value zero commitment more than a lower average rate. Some renters and short-term residents assign real value to "I can leave next month," even if it costs them about 15 percent more per year on average. That is a reasonable preference.

If none of those describe you, fixed is almost certainly the better plan.

Fixed-Rate Contract Fine Print to Read First

The most common error in Texas electricity plan shopping is looking at the advertised rate and ignoring the fine print. Before you enroll, check these five items on the EFL:

• The bill-credit tier. If the advertised rate assumes exactly 1,000 kilowatt-hours per month and you use 850, your effective rate can end up 20 to 40 percent higher.
• The base charge. A $9.95 monthly base charge on a low-usage account can equal 4 cents per kilowatt-hour by itself.
• The TDU pass-through structure. Some plans include TDU delivery charges in the advertised rate. Others bill them separately.
• The renewable content. Texas has strong wind and solar generation. If green energy matters to you, look for plans that disclose renewable percentage.
• The early termination fee. Confirm the dollar amount and whether it prorates as you approach the end of the term.

Thomas Gleeson, Chairman of the Public Utility Commission of Texas, told the Express-News in May 2025 that a top priority of his office was "reinstilling the public's faith in the PUC." The EFL is the single document the PUCT requires every provider to give you before enrollment. Read it.

Beyond Fixed vs Variable: Time-of-Use, Free Nights, and Solar Buyback

Texas is a deregulated retail market, which means providers compete not just on rate but on plan structure. After you have chosen fixed or variable, you can layer on:

• Free Nights and Free Weekends plans. Energy is free during specified hours in exchange for a slightly higher daytime rate. This works well for households that can shift laundry, dishwashing, and EV charging into off-peak windows. See the Free Nights Plan Calculator to run the math on whether the structure fits your usage.
• Time-of-Use plans. More granular than Free Nights, with three or four rate periods per day. Best for households with automated smart-home controls.
• Solar Buyback plans. If you have rooftop solar, a buyback plan credits your bill for excess generation. Ambit Energy's solar buyback options are covered in the Best Solar Buyback Plans in Texas guide.

Layer these on top of the fixed-versus-variable choice, not instead of it.

Your Next Step

Pull one EFL for a fixed 12-month plan in your ZIP code and one EFL for a month-to-month variable plan in your ZIP code. Run each through the five-question Texas Rate Reality Check. If your answers point to fixed, lock it in before the next ERCOT summer tightness cycle. If they point to variable, set a monthly calendar reminder to reshop rates. Ambit Energy has served Texas households since 2006 and can walk you through both options in the deregulated portion of your ZIP.

Frequently Asked Questions

Is a fixed or variable electricity plan better in Texas?
For most Texas households on a horizon of a year or more, fixed is better because it insulates you from ERCOT wholesale price spikes like the Winter Storm Uri event in February 2021 and the August 2023 heat wave. Variable makes sense for short-term residents or households actively monitoring the market.

How much can a variable electricity rate change in Texas in one month?
There is no cap under a standard variable plan. Historically, rates have moved from roughly 12 cents per kilowatt-hour to more than 20 cents per kilowatt-hour in a single billing cycle during summer demand spikes. Wholesale ERCOT prices themselves have swung from about $20 per megawatt-hour to $5,000 per megawatt-hour within hours during extreme weather.

Can my fixed rate really change during the contract?
Only the pass-through charges. The energy charge you signed for stays locked. TDU delivery charges (Oncor, CenterPoint, AEP, TNMP) can change if the PUCT approves a rate case, and ERCOT administrative fees can move. Your Electricity Facts Label documents which charges can move and which are locked.

With shopping for Texas electricity plans in 2026, it is nearly like being in a store with 1,800 different price tags and no clear way to know what you will actually pay. On any given week, state-run shopping site Power to Choose lists almost that many active plans, and the headline cents per kWh figure at the top of each listing is nearly never what your end-of-the-month bill will look like.

The good thing is that once you know what the rate actually hides, comparing Texas electricity plans becomes easier.

The 5 Plan Types Texans Actually Choose From in 2026

Every listing on Power to Choose fits into one of five categories. For your household, it is much more important to select the proper category than to select the cheapest option within the incorrect category.

1. Fixed-rate plans. The energy charge will remain constant for the entire term of the contract, which is typically 12, 24, or 36 months. This option is predictable and budget-friendly, and is the default recommendation for most Texas households according to consumer education sites.

2. Variable-rate plans. These plans allow providers to change rates at will from month to month. These plans often start off at a cheap rate, but then the rate tends to increase after some time. This is why they are advertised as month-to-month plans after a fixed-rate contract ends.

3. Indexed plans. These plans tie your rate to a published index which usually tracks day-ahead wholesale prices in the ERCOT market. According to Utility Dive market summaries, load-weighted wholesale prices averaged about $47 per MWh across 2025. While that sounds cheap, be prepared for a cold snap in February when prices jump to the market cap.

4. Plans with Free Nights or Free Weekends (time-of-use). For these plans, energy charges are zero for defined time windows (typically from 8 p.m. to 6 a.m., or all weekend). Outside this window, the price rises above the market average. Consumer explainers note that these plans can only be economically beneficial if customers move their laundry, dishwasher runs, and EV charging to the free periods. Our breakdown of free nights vs free weekends walks through the math.

5. Prepaid plans. There is no deposit, no credit check, and no long-term contract. Instead, these plans offer a higher per-kWh rate and little to no protection if the provider hikes their rates or if you get close to being out of funds.

Why the Headline Rate on Power to Choose Is Almost Always Wrong

When Power to Choose first launched, it aimed to make the Texas retail electricity market more transparent. Unfortunately, the way the site has presented plans has taught a whole generation of consumers to look at the wrong number.

The rate shown at the top of every listing is called the "advertised rate at 1,000 kWh," which means it is the total bill at exactly 1,000 kWh of monthly usage divided by 1,000. There are three things it distorts, and two things it does not include:

• The delivery charges from your Transmission and Distribution Utility (TDU) are included, but only at 1,000 kWh. This means every time your usage changes, the effective delivery cost will change.
• The bill credits and minimum-usage credits are included, but only if you fall within the usage range that the credit rewards.
• The base monthly charges are averaged over 1,000 kWh, which reduces their impact if you have a smaller household.

Although Power to Choose uses its own TruBill estimator to smooth some of this out, it still assumes a stylized usage curve. Your bill is a reflection of your household, not a curve on a state website.

The Real-Rate Framework: 5 Layers That Determine Your Actual Bill

Every Texas electricity bill consists of five layers. Add them up in this order, and you get the number that will actually appear on your statement.

Layer 1: The energy supply rate. This is the cents per kWh that the retail electric provider (REP) charges for the electricity itself. Depending on the length of the contract and the plan type, this can range from about 8 cents to more than 20 cents.

Layer 2: The TDU delivery charges. The transmission and distribution utility (Oncor, CenterPoint, AEP Texas, TNMP) delivers to all homes in their service areas regardless of which REP you purchase electricity from. Delivery charges range from roughly 30 to 40 percent of a typical Texas residential bill in 2025 and 2026, per Just Energy's rate breakdown. The delivery charge per kWh sits in the 3.2 to 4.1 cents range, plus a base monthly charge from $5 to $9. See our recent TDU delivery-charge update for the June 2026 change.

Layer 3: Base monthly charges from the REP. Many plans include a $9.95 or $12.95 monthly base fee that hits the same way whether you use 500 kWh or 3,000 kWh. On a small apartment bill, that base fee alone can add 2 cents to the effective rate.

Layer 4: Conditional bill credits. A plan that appears outstanding at 1,001 kWh and mediocre at 999 kWh will likely have a $75 or $100 monthly credit that only triggers between 1,000 and 2,000 kWh. This is where most Texans get burned.

Layer 5: Time-of-use structure. If a plan has an indexed component, free nights, or free weekends, your bill will depend on when you use electricity, not just how much. A daytime-heavy household on a free-nights plan can pay 3 to 5 cents more per kWh than a fixed-rate shopper next door.

Total every layer at your actual monthly usage to see the real rate. That is the figure to compare with other plans.

How TDU Delivery Charges Change Your Comparison

The TDU delivery charge is a mystery to most Texans reading their electric bill. These charges are on all bills, regardless of whether you buy from Ambit, TXU, Reliant, or any other REP, because the physical wires belong to the utility, not the provider.

Most Texas TDUs adjust their delivery rates around June each year. With Oncor, for example, delivery charges increased by almost 0.5 cents per kWh between March and June (as of June 2026). Rate changes like this happen on a regular schedule, and every household in the utility's territory sees them roll through their bills. The Public Utility Commission of Texas (PUCT) approves the tariffs for delivery rates, and you can find reports on system reliability and market data at ercot.com. See our coverage of the Oncor rate increase in 2026 for the household impact.

There are two key points to keep in mind when shopping. First, when you are comparing two plans on the same Power to Choose listing, you are making a fair apples-to-apples comparison, because they all include the same TDU line. Second, once you have chosen a plan, TDU adjustments will still be applied to your bill, even if your supply rate is locked. If your neighbor's bill increased in June, the plan you signed is not the reason: TDU delivery is most often the culprit.

The 1,000 kWh Trap: How Bill Credits Hide the Real Rate

The pitfall we see most frequently on the Ambit team is what we call the 1,000 kWh trap. One common plan structure in the market advertises a rate of 9.8 cents per kWh at 1,000 kWh because a $75 bill credit is applied at that usage. If you sit at 999 kWh, though, the credit disappears and the effective rate spikes over 17 cents. Then at 2,000 kWh, the same credit reduces the effective savings per kWh to 3.75 cents, and the rate drifts back up.

Texas Electricity Ratings' TruBill breakdowns show this exact behavior across many currently marketed plans. Their published rate tables illustrate a plan whose effective rate is 16.9 cents at 250 kWh, drops to 11.9 cents at 1,000 kWh, and climbs back to 13.4 cents at 3,000 kWh. That is not a rate; that is a rate curve. Our EFL walkthrough for free nights plans shows the same effect in a different plan family.

A practical rule is this. Pull the highest bill from last summer (usually July or August) and the mildest bill from last winter (usually November or March). Those two numbers bracket your household. If a plan looks great at 1,000 kWh but ugly at 2,000 kWh, and you consistently reach 2,000 kWh in August, that plan is not for you.

Matching Plan Type to Your Actual Household Usage

Once you understand the Real-Rate Framework, matching a plan type to your household is straightforward.

• Predictable-usage household, wants to set it and forget it. Fixed rate, 12 to 24 months, no unusual bill credit tiers. Best for young families and retirees who value budget certainty.
• Large home with heavy summer AC usage. Fixed rate plus a bill credit that triggers at 2,000 kWh or more, if your typical summer usage clears the trigger every month. Otherwise, a straight fixed rate.
• Small apartment or empty nester. Fixed rate with no minimum-usage penalty and the lowest possible base monthly charge. Bill credits at 1,000 kWh will hurt you.
• EV household or shift worker home during off-peak hours. Free nights or free weekends plan, only if you can actually shift laundry, dishwashing, pool pumps, and EV charging into the free window. Our best free nights plans by ZIP code comparison narrows the field.
• Solar homeowner with net-metering interest. A solar buyback plan (a specialized subset of fixed rate) that credits excess generation.
• Renter with no credit history. Prepaid, understanding the higher per-kWh cost is the price of no deposit. Subject to credit approval on non-prepaid plans.

The cheapest plan and the plan that is "right for you" are almost never the same plan.

What Changes in 2026: ERCOT Demand Growth and Why Variable Plans Got Riskier

ERCOT's demand outlook for 2026 is an outlier. The Energy Information Administration's 2026 electricity outlook projects a large ERCOT load increase this year, driven mainly by data center connections and continued population growth across the DFW, Houston, and San Antonio metros. On June 18, 2026, the Public Utility Commission of Texas approved ERCOT's Batch Zero process for managing large-user connection requests, a framework covered by Reuters and the Texas Energy Report.

For households, the practical implication is that demand rising into a supply base that has not grown as fast means wholesale price volatility will keep increasing. Variable and indexed plans that looked appealing in 2023 and 2024 are riskier bets going into the summer of 2026 and beyond. Fixed rates carry a premium over the current market, but that premium is what you pay for insulation from a July peak-price event.

Consumer advocates including Alison Silverstein, a longtime Texas grid analyst who has served as a senior advisor to federal energy regulators, have consistently argued that residential shoppers underestimate market volatility. Beth Garza, who ran the ERCOT Independent Market Monitor at Potomac Economics, has published similar warnings about the way retail rate structures obscure wholesale risk.

7 Questions to Ask Before You Enroll

Before you click enroll on any Texas electricity plan, run through this checklist.

1. What is the effective rate at my actual monthly usage in July and in November?
2. Are there bill credits, and at what exact usage thresholds do they apply?
3. What is the monthly base fee, and does it hit at zero usage?
4. Is the rate fixed, variable, or indexed for the contract term?
5. What is the early termination fee if I move or switch?
6. Do the TDU charges on this plan match what I am paying today, or is there something unusual?
7. Does the free-nights or free-weekends window match how my household actually uses electricity?

If a plan cannot answer question 1 cleanly from its Electricity Facts Label (EFL), that is the answer.

Frequently Asked Questions

Are fixed-rate plans always cheaper than variable-rate plans in Texas?
No. Variable plans can be cheaper when wholesale prices are low, but they expose you to spikes when the ERCOT market tightens. Fixed rates are cheaper over a full 12-month cycle for most Texas households because they smooth out summer peaks.

What percentage of my Texas electricity bill is TDU delivery charges?
Delivery charges from Oncor, CenterPoint, AEP Texas, or TNMP make up roughly 30 to 40 percent of a typical residential bill, per Just Energy's 2025 rate breakdown. The percentage is higher for low-usage households and lower for high-usage households.

Why does the same plan cost different amounts on Power to Choose than on the provider's own site?
Power to Choose shows the effective rate at 500, 1,000, and 2,000 kWh with TDU charges and bill credits included. Provider sites often show the base energy rate before delivery charges and credits, which is why the numbers look different. Always compare the total estimated bill, not the headline rate.

Is Power to Choose the only place to compare Texas electricity plans?
No. Power to Choose is the official state site, but private aggregators like ChooseTexasPower and Texas Electricity Ratings publish more detailed tools including bill credit modeling and Safe-Rate scoring. Using two sources is the safest way to catch a plan that looks great on one site and terrible on another.

Ready to Pick the Right Plan

Comparing Texas electricity plans in 2026 comes down to one thing: knowing the layers underneath the headline rate. Once you can price out a plan against your own usage (not the 1,000 kWh average) you can shop with confidence and stop paying for structure that does not fit your household.

For Texas residential homeowners and renters shopping the deregulated retail electricity market. Plan details and rates are subject to change; the Energy Facts Label available from each REP is the authoritative source for price, term, and fees.

Free nights plans in Texas may look the same across a consumer's screen, but actually, the plans you can sign up for are determined by your ZIP code. Your ZIP code, which gives your friends an easy way to send you a birthday card, tells the grid which Transmission and Distribution Utility (TDU) powers you, and that TDU dictates which retail providers, and subsequently, which free nights plans are offered to you.

I see this confusion every week. A homeowner reads a comparison page and sees a plan with a 9 p.m. to 6 a.m. free window, signs up, and learns at enrollment that the plan is not offered in their service territory. Even worse, a household in a city like Austin or San Antonio has no choice at all because a city utility, not a retail provider, owns the meter.

This guide clears up that confusion. I will connect the five Texas TDUs to cities and ZIP prefixes, explain the municipal and cooperative carve-outs that block access, and detail an original framework I built and call the ZIP-to-Match Framework, a 3-step process to land on the best free nights plan for your address.

Why Your ZIP Code Determines Which Free Nights Plans You Can Purchase

Most of Texas runs a deregulated retail electricity market, a structure created by Senate Bill 7, signed by Governor George W. Bush on June 18, 1999, and phased in to customers starting January 1, 2002. According to coverage and historical data summarized in the public deregulation overview of the Texas electricity market, about 85 percent of Texas power consumers shop in this deregulated zone. The remaining 15 percent either live in cities that chose to stay bundled or in rural co-ops.

The deregulated zone is unusually wide open on the supply side. According to the PUCT's alphabetical directory of Retail Electric Providers, 140 active REPs are licensed to sell power in Texas as of the most recent directory update.

Each address in this zone has two companies serving it:

1. The TDU (sometimes called a TDSP) owns the poles and wires, does the meter reading, and is responsible for any outages. You do not have a choice about which TDU you have. It is determined by your address.
2. The retail electricity provider (REP) does the billing, sets a price per kilowatt hour, and determines what the plan looks like, including if it has free nights or free weekends.

Free nights plans are a product of retail marketing. Each REP files its plans with a specific TDU footprint at the Public Utility Commission of Texas (PUCT), but REPs are not obligated to file plans for every TDU. That is why one retailer may have free nights plans in Houston (CenterPoint Energy territory) but not in Lubbock (Oncor and South Plains Electric Co-op territory), and vice versa.

The PUCT's official shopping site, Power To Choose, is the quickest way to see which plans your ZIP code is eligible for. Enter your ZIP code, filter by "Plan Type," and select time-of-use. Plans that are unavailable in your area will not show up.

The Five TDUs That Power Texas (And the ZIPs They Cover)

The deregulated section of the Electric Reliability Council of Texas (ERCOT) is served by five TDUs. ERCOT runs the grid for about 90 percent of the state's electric load. According to ERCOT's all-time peak demand records page, the grid set its all-time peak demand record at 85,508 MW on August 10, 2023. The TDU maps below come from each utility's published service-area documents.

Oncor Electric Delivery

Oncor is the largest TDU in the state by customer count. According to Oncor's published company facts, the utility serves over 4 million meters across about 400 cities. Major service areas include:

• The Dallas-Fort Worth metroplex and most neighboring suburbs (Frisco, Plano, Irving, Arlington, Carrollton, Grand Prairie, McKinney)
• Tyler, Killeen, Waco, Midland, Odessa, and the Permian Basin
• Most ZIP prefixes 75xxx, 76xxx, and a portion of 79xxx in West Texas

Verify Oncor coverage on the Oncor service area lookup.

CenterPoint Energy Houston Electric

CenterPoint extends to the greater Houston metropolitan area and a ring of Gulf Coast counties down to the Brazoria line. According to CenterPoint's published company facts, CenterPoint serves over 2.7 million metered customers.

• Houston, Pasadena, Sugar Land, The Woodlands, Katy, Pearland, Baytown, Texas City, Galveston
• Most ZIP prefixes of 77xxx and part of 78xxx near the coastline
• CenterPoint's ZIP-by-service-center directory is the authoritative map

AEP Texas Central

AEP Texas Central services the coastal bend and Lower Rio Grande Valley.

• Corpus Christi, Victoria, Laredo, McAllen, Harlingen, Brownsville, Edinburg
• Parts of ZIP codes 78xxx and 79xxx (Valley)
• A small portion of South Texas around the Eagle Ford shale

AEP Texas North

AEP Texas North serves the Abilene and West-Central Texas region.

• Abilene, San Angelo, Vernon, portions of the Big Country and Hill Country edges
• Predominantly ZIP prefixes 76xxx (west) and 79xxx
• Smaller customer count than the other AEP arm, but the same retail plan footprint typically applies

Texas-New Mexico Power (TNMP)

TNMP serves pockets, not connected regions, which is what trips up new Texans the most.

• Lewisville and parts of north DFW, Texas City, League City, Friendswood, Alvin
• Parts of the Gulf Coast south of Houston
• Sections of the Panhandle and Permian Basin
• ZIP prefixes scattered across 75xxx, 77xxx, and 79xxx

Given the patchy nature of TNMP territory, a ZIP-level check at Power To Choose is critical here. Two neighbors a mile apart may have different TDUs, and therefore different free nights plans available.

The ZIP-to-Match Framework: My 3-Step Free Nights Decision Flow

I built this framework after running the same plan-fit check for households across all five TDUs. The ZIP-to-Match Framework is an original 3-step process I use that takes about 20 minutes and prevents the most common overpay mistake, which is signing up for a free nights plan when the household's actual usage profile makes it a worse deal than a flat rate.

The framework has three sequential steps. Each step has a clear input (something you can pull from a public source) and a clear output (a decision you can act on).

Framework Step 1: Identify Your TDU

Use your service ZIP at Power To Choose to determine your TDU. The site will display the TDU beside the rates. For areas with multiple TDUs (common in suburbs and near city limit lines), check your latest electric bill for a line item labeled "TDU Delivery Charges," "Delivery Fees," or similar.

Why this matters: a free nights plan from Reliant runs on the Reliant retail side, but the TDU charges, which can account for about 25 to 35 percent of a typical residential bill per analysis from independent shopping marketplaces, are passed through whether your bedtime is 8 p.m. or midnight. Knowing your TDU is also the only way to compare like to like across plans.

Framework Step 2: Map Your Free Window to Your Actual Usage

The free hours are different for each plan. Here is a breakdown of the major Texas free nights offers and their free windows:

• Reliant Truly Free Nights: 8 p.m. to 6 a.m.
• TXU Free Nights and Weekends: 9 p.m. to 6 a.m.
• Just Energy Nights Free: 9 p.m. to 7 a.m.
• Direct Energy Twelve-Hour Power: 9 p.m. to 8:59 a.m.
• Reliant Truly Free Weekends: 8 p.m. Friday to 12 a.m. Monday
• Direct Energy Free Power Weekends: 6 p.m. Friday to 11:59 p.m. Sunday

Texas requires every deregulated REP to provide kWh data through the state's Smart Meter Texas portal, in 15-minute intervals. Register your account, download a recent 30-day usage CSV, and add up the kWh that falls inside the plan's free window.

According to EIA-cited figures aggregated by ChooseTexasPower, the average Texas residential household uses about 1,096 kWh per month, among the highest residential usage figures in the country. That high baseline is what makes free nights plans interesting in Texas in the first place, but only if enough of it lands inside the free window.

The 20/35 rule of thumb I use inside the framework:

• If 35 percent or more of your monthly kWh falls inside the plan's free window, a free nights plan likely wins.
• If it is below 20 percent, a flat-rate fixed plan almost always beats it because the daytime rate is elevated to subsidize the free hours.
• If you are between 20 and 35 percent, a free nights and weekends plan (not just nights) is the safer bet.

Framework Step 3: Read the EFL Like an Auditor

Every Texas retail plan must publish an Electricity Facts Label (EFL), a one-page disclosure mandated by PUCT Substantive Rule 25.475. The EFL lists the average price per kWh at 500, 1,000, and 2,000 kWh of monthly usage, the contract length, the early termination fee, and the energy charge during peak hours.

Three lines I check on every free nights EFL:

1. The daytime kWh rate (the headline "free" hours hide here)
2. The 1,000 kWh average price vs. the 2,000 kWh average price (a wide gap means heavy daytime use will sting)
3. The minimum monthly usage charge that some REPs add at low monthly kWh

You can request any plan's EFL directly from the REP, or pull it from Power To Choose by clicking the plan name.

The framework's value is in the order: TDU first (so the candidate plan list is real), usage second (so the math is yours, not a marketing chart's), EFL third (so the contract terms back up the rate). Skip any step and the answer gets less reliable.

Free Nights Plans Available by TDU Service Area

Plan availability and free hours change as REPs file new versions with PUCT. Use the table to narrow the shortlist, then confirm on the EFL the day you enroll.

For a deeper read on the trade-offs, my free nights vs. free weekends comparison and the pillar guide Free Nights Electricity Plans in Texas go deeper than the table.

Cities Where Free Nights Plans Are Off the Table

If you live inside one of these service areas, you cannot shop a retail free nights plan. The local utility is the only seller, and its rate structure may or may not include a time-of-use option. Always call the utility to confirm.

• Austin Energy (Austin)
• CPS Energy (San Antonio)
• Brownsville Public Utilities Board
• Denton Municipal Electric (Denton)
• Garland Power and Light
• Greenville Electric Utility System
• College Station Utilities
• Bryan Texas Utilities
• New Braunfels Utilities
• San Marcos Electric Utility
• Lubbock Power and Light (now operating inside ERCOT but still municipally owned)
• Pedernales Electric Cooperative (Hill Country)
• Bluebonnet Electric Cooperative (Central Texas)
• Guadalupe Valley Electric Cooperative (GVEC)
• Magic Valley Electric Cooperative
• Bandera Electric Cooperative
• Bartlett Electric Cooperative
• Brazos Electric Cooperative

If your address falls inside one of these, the right move is usually a behavior shift (run laundry and dishwashers off-peak, set the thermostat back overnight) rather than waiting for a free nights plan that will not come. My piece on shifting your energy usage to nights walks through the behavior side.

How to Verify Your TDU Before You Sign Up

Three checks, in order of speed:

1. Power To Choose by ZIP. Free, immediate. Returns the TDU and the plans filed for that territory. (powertochoose.org)
2. Read the delivery line on your bill. TDU charges are itemized as "TDU Delivery Charges," "Delivery Fees," or "TDSP Charges." The provider name is on that line.
3. Call the TDU outage line. If you have ever been told to call a specific number when your power goes out (Oncor 888-313-4747, CenterPoint 713-207-2222, AEP Texas 866-223-8508, TNMP 888-866-7456), that is your TDU.

Households in Texas frequently sign up for incorrect plans because they skip this check. Dr. Joshua Rhodes, a research scientist at the University of Texas at Austin's Webber Energy Group, said in published Texas grid analyses that time-of-use plans are effective if and only if the household's load profile aligns with the rate structure. Dr. Michael E. Webber, Josey Centennial Professor in Energy Resources at UT Austin and founder of the Webber Energy Group, said that retail electricity choice in Texas pays off only when customers do the homework on their own load shape rather than chasing a headline rate. Lynne Kiesling, PhD, an energy economist and research professor at Carnegie Mellon University's College of Engineering, has likewise argued that time-of-use rates only deliver consumer welfare when paired with transparent disclosure of the underlying tariff structure. The TDU-and-EFL check is how you do that homework before you sign, not after.

ZIP-Specific Pitfalls That Cost Texas Households Money

Four traps I see repeatedly:

1. Border ZIPs with multiple TDUs. A single ZIP code in Lewisville can route Oncor on one side of a street and TNMP on the other. Always verify by service address, not just ZIP.
2. The "free" rate buried inside a high daytime rate. PUCT EFL data shows free nights plans frequently have a daytime energy charge 30 to 60 percent above a flat fixed-rate plan in the same TDU. If your day kWh is high, the math breaks.
3. EV owners on the wrong window. Smart charging at home is the easiest win on a free nights plan, but only if you can shift the full charge into the window. The EV owners free nights guide breaks down the charge math.
4. Auto-renew at a higher rate. Texas contracts can roll into a holdover variable rate at the end of a term. Set a calendar alert 30 days before your contract end and re-shop the plan. State law allows you to switch without an early termination fee inside the final 14 days of the contract.

A look at solar plus battery plus free nights, for households that pair the plan with rooftop generation, lives in the Texas Triple Play piece.

Frequently Asked Questions

Are free nights plans offered in every Texas ZIP code?

No. They are sold only in the deregulated portion of ERCOT, which covers about 85 percent of Texas power customers. If your ZIP falls inside a municipal utility (Austin Energy, CPS Energy, Denton Municipal Electric, and others) or a non-deregulated co-op, you cannot enroll in a retail free nights plan. The municipal utility may still offer a time-of-use rate; call to ask.

How do I find my TDU from my ZIP code alone?

Enter your ZIP at powertochoose.org and the TDU will appear beside the plan list. If your ZIP falls in a multi-TDU area (common in DFW suburbs and Gulf Coast suburbs), the site will ask for your address. Cross-check by looking at "TDU Delivery Charges" on your current bill.

Which Texas free nights plan has the longest free window?

As of recent EFL filings, Direct Energy Twelve-Hour Power offers 9 p.m. to 8:59 a.m., the widest of the major plans. Reliant Truly Free Nights runs 8 p.m. to 6 a.m., a 10-hour window with the earliest start.

Do free nights plans cost more for daytime electricity?

Yes. Industry analysis of Texas EFLs shows daytime energy charges on free nights plans run 30 to 60 percent higher than the daytime portion of a comparable fixed-rate plan in the same TDU. The math works only when your free-window usage is high enough to offset the elevated day rate.

Can I switch to a free nights plan if I am in a current contract?

You can, but you may owe an early termination fee. Texas law removes the fee if you are moving to a new address. Without a move, the fee is typically 150 to 295 dollars depending on the REP. The PUCT requires the fee amount on the EFL.

Do free nights plans exist for small businesses?

A few REPs offer commercial time-of-use products in deregulated territory, but most free nights plans are residential. A commercial broker can run a quote by ZIP and meter type if your business runs a heavy nighttime load profile.

What I Would Do Next

If you are in deregulated Texas, run the ZIP-to-Match Framework this week:

1. Get your TDU from Power To Choose or the delivery line on your bill.
2. Pull a 30-day Smart Meter Texas CSV and sum the kWh inside the free windows you are considering.
3. Compare the EFL average prices at 1,000 and 2,000 kWh, not the headline rate.

If your free-window share of usage is at least 35 percent, a free nights plan in your TDU footprint is likely the cheaper path. If it is below 20 percent, a flat fixed-rate plan will save more money with less behavior change required.

For a side-by-side review of the underlying product, the pillar guide Free Nights Electricity Plans in Texas covers every plan currently filed with PUCT in the major TDU footprints. If you are still on the fence about whether a free nights plan fits your household at all, my are free nights plans worth it analysis is the better starting point.

Free nights plans reward households that can move load. Your ZIP code tells you whether you can play the game in the first place, and if you can, which version of the game is available at your door.

Important Information

Plan details and rates are subject to change; the Energy Facts Label available from each retail provider is the authoritative source for price, term, and fees. Enrollment is subject to credit approval and provider availability at your service address.

A Texas free nights electricity plan is only as honest as the Electricity Facts Label (EFL) that defines it. Under Public Utility Commission of Texas Substantive Rule 25.475, every retail electric provider in the deregulated ERCOT market must publish a standardized EFL that lists the average price per kilowatt-hour (kWh) at 500, 1,000, and 2,000 kWh. For a free nights plan, that headline price embeds an assumed split between daytime and overnight usage; as of mid-2026 SaveOnEnergy filings, the energy charge during paid daytime hours commonly runs in the $0.18 to $0.25 per kWh range. Read the EFL line by line before you sign and you will know in under ten minutes whether the plan saves your Texas household money or quietly costs more than a fixed rate alternative. Plan details and rates are subject to change, and the Energy Facts Label is available for every plan on Power to Choose or the provider's website.

What Is an Electricity Facts Label?

An Electricity Facts Label (EFL) is a one to two page document that every retail electric provider (REP) has to publish for each plan it sells in the deregulated ERCOT market. The Public Utility Commission of Texas (PUCT) created the EFL so Texas residents can evaluate competing plans on a uniform scorecard rather than on advertising promotions.

A compliant EFL must include the average price per kWh at 500, 1,000, and 2,000 kWh, the energy charge, the transmission and distribution utility (TDU) delivery charges, base or minimum usage fees, bill credit thresholds, contract length, the early termination fee, and the percentage of renewable content. All numbers on the label must be consistent with the Terms of Service and Your Rights as a Customer documents. The PUCT enforces compliance through complaint investigations and through the Power to Choose database.

For Texas households in deregulated TDU territory served by Oncor, CenterPoint, AEP Texas, or Texas New Mexico Power, the EFL is the only legal pricing document. Households inside municipal utility cities (the largest examples being the capital city and the city of San Antonio) do not shop EFLs at all because those markets are not deregulated, so this guide does not apply to those Texas households.

The Seven Section EFL Audit: Our Line By Line Framework

At VIP Energy Service we apply a Seven Section EFL Audit when guiding a Texas household through a free nights comparison. This is the named framework we teach the consultants in our organization to use with every prospect, and it is the same checklist we apply to any plan we review.

1. Plan identity and term. Confirm the plan name, the REP legal name and PUCT certificate number, the contract term in months, and any auto renewal language.
2. Average price at 1,000 kWh. This is the headline number and it embeds the EFL's assumed free window split. Compare it to the same line on three competing EFLs.
3. Average price at 500 kWh and 2,000 kWh. A free nights plan that looks affordable at 2,000 kWh can be punishing at 500 kWh. Match the row to the household's actual usage from a recent bill.
4. The energy charge during paid hours. This is the per-kWh price the household actually pays between roughly 6 or 7 a.m. and 8 or 9 p.m., depending on the plan. As of mid-2026 SaveOnEnergy filings, daytime energy charges on Texas free nights plans commonly run in the $0.18 to $0.25 per kWh range.
5. TDU delivery charges. Even during the free window, the wires company charge applies to every kWh delivered. This is set by the TDU, not the REP, so the per-kWh amount is identical across REPs in the same TDU territory.
6. Base or minimum usage fees. Look for a flat monthly base charge, a minimum usage fee triggered below a threshold (typically 1,000 kWh), or a bill credit only paid above a threshold.
7. Free window start and end times, time zone, and renewal rules. Confirm the window is in Central Time, applies seven days a week, and does not shrink under off peak exceptions.

Running these seven checks in parallel on two or three competing EFLs makes the right answer for a Texas household very clear.

Where the EFL Hides the Real Rate During Paid Hours

The most overlooked line on a free nights EFL is the daytime energy charge. The marketing headline average price at 1,000 kWh gets all the attention, but that average already assumes a specific share of the household's usage falls inside the free window. If real usage skews more daytime than the EFL's assumption, the household pays the daytime energy charge on more kWh than the headline price suggests.

For most Texas free nights plans, the daytime energy charge appears in the pricing section as a line that reads something like, as of the EFL effective date, "Energy Charge (Monday to Sunday, 6 a.m. to 8 p.m.): $0.215 per kWh." PUCT rule requires the EFL to spell that out. What happens in practice is that consumers see the bolded headline number and skip the table that produced it.

The Constellation Energy 101 guide to reading EFLs makes this point plainly: the average price you see depends on how much electricity you use during specific times. Without evaluating the underlying energy charge, the household cannot tell whether the headline average is realistic.

How to Calculate Your Actual Monthly Cost From the EFL

To determine the household's real monthly cost, six inputs are required from the EFL plus the last bill.

1. Monthly usage in kWh. Pull this from the most recent statement or the Smart Meter Texas account.
2. Daytime usage percentage. According to U.S. Energy Information Administration data on Texas residential load shapes, household demand bottoms out around 5 a.m. and peaks in the late afternoon and early evening. A typical Texas household runs roughly 60 to 75 percent of its kWh during paid daytime hours; an EV charging overnight household with smart thermostat setbacks can flip that.
3. The daytime energy charge from the EFL.
4. The TDU energy delivery rate from the EFL, expressed per kWh.
5. The TDU monthly fixed charge.
6. Any base, minimum usage, or bill credit thresholds.

The formula is simple.

Monthly cost = (kWh times daytime share) times (daytime energy charge plus TDU per-kWh delivery) plus the TDU monthly fixed charge plus any base or minimum usage fee, minus any earned bill credit.

Compare the answer to the same calculation against a fixed rate plan's EFL at the household's usage level. The plan with the lower honest number wins, not the one with the catchier marketing. Plan details and rates are subject to change after the EFL effective date.

The Most Common Hidden Fees on a Free Nights EFL

Hidden is the wrong word, because every fee we are about to list is disclosed on the EFL itself. They are simply easy to miss when the eye chases the headline. The four we see most often:

• Monthly base charge. A flat dollar amount, often between 9.95 and 14.95 dollars (as of recent filings), applied regardless of usage.
• Minimum usage fee. A penalty (commonly 9.99 dollars as of recent filings) triggered when monthly usage falls below a threshold, typically 1,000 kWh.
• Bill credit threshold. A bill credit (for example, 50 dollars off when usage exceeds 1,000 kWh) that vanishes any month the household falls below the line.
• Early termination fee (ETF). Standardized at 150 to 295 dollars on 12 to 36 month plans as of recent filings. The ETF is disclosed on the EFL and the Terms of Service.

Any of these four can flip the breakeven on a free nights plan. A Texas household that lands at 950 kWh in a mild April can lose a 50 dollar bill credit and pay a 9.99 dollar minimum usage fee in the same statement, swallowing the savings the free window earned the rest of the year.

How the EFL Discloses the Start and End Times of Free Hours

Free window times appear in the pricing or plan description section of the EFL in plain text. A compliant EFL states the exact start time, end time, time zone, and days of the week the free window applies. Common phrasings include "Free electricity Monday through Sunday, 9 p.m. to 7 a.m. Central Time" or "Free Nights, 8 p.m. to 6 a.m. CT."

Three details to verify before signing:

• The window is at least eight consecutive hours. Shorter free windows usually carry a higher daytime rate to fund them.
• The window applies every night, including weekends and holidays. Some plans exclude certain dates.
• The window is anchored in Central Time and does not shift with daylight saving in a way that shortens it.

If the EFL is vague on any of these, request the Terms of Service. PUCT rules require every claim on the EFL to be matched in the Terms of Service.

The PUCT Rules That Govern EFL Disclosure

Substantive Rule 25.475 is the master rule, codified in 16 Texas Administrative Code and enforced by the PUCT's Customer Protection Division. The essential elements:

• Every EFL must be unique to the product and to the TDU territory it is sold in.
• The label may not exceed two pages and must use the minimum font size set in the rule.
• The average price calculation must follow the PUCT formula at 500, 1,000, and 2,000 kWh.
• Any change to the plan requires a new EFL and customer notification.
• Administrative penalties can result from misleading marketing claims (unconditional "free" promotions and deceptive free windows, for example).

In 2024 retail market oversight reporting, PUCT staff noted that pricing disclosures on time of use products, including free nights and free weekends plans, remain a continuing area of complaint volume from Texas consumers. That is one reason we recommend the line by line audit before any switch.

For consumers who want to file a complaint, the PUCT Customer Protection Division at 1-888-782-8477 handles EFL related disputes directly.

How VIP Energy Service Compares EFLs for You

We are a Texas based Ambit Energy independent consultant organization, and EFL review is part of every household consultation we run. When a Texas homeowner asks whether a free nights plan saves money, we apply our Seven Section EFL Audit to three plans side by side: the free nights plan in question, a comparable fixed rate plan from another REP, and a free weekends plan if the household's usage skews to Saturday and Sunday.

We pull each plan's EFL directly from the Power to Choose database or the REP's website. We rebuild the average price calculation against the household's actual usage from the last twelve bills, not against the EFL's assumed split. We flag every base charge, minimum usage fee, and bill credit threshold. Then we hand the Texas homeowner a one page side by side comparison they can take to any provider for a second opinion. (We are an independent consultant organization and individual consultant earnings vary; results are not guaranteed.)

We also tell homeowners when a free nights plan is genuinely the right answer. EV owners who can shift most charging overnight, work from home households with smart thermostats and pool pumps on timers, and battery storage owners all tend to land on the affordable side of a free nights EFL. Households with daytime weekday occupants, electric resistance heat in winter, or west facing peak afternoon cooling load usually do not.

For deeper context on when a free nights plan does and does not pay off, our companion guides cover free nights versus free weekends math, how free nights energy plans work and who they fit, whether free nights plans are worth it overall, and the solar, battery, and free nights triple play.

If you would like a free EFL review on a plan you are considering, you can request one through our contact form. We do not charge for the analysis and we give you the honest answer even when the honest answer is that a fixed rate plan from another REP wins. Plan details and rates are subject to change, and the Energy Facts Label is available for every plan on Power to Choose or the provider's website. Subject to credit approval.

Frequently Asked Questions

What is an Electricity Facts Label?

An Electricity Facts Label is a standardized one to two page disclosure required by Public Utility Commission of Texas Substantive Rule 25.475 that lists every price, fee, and contract term of a retail electricity plan in a fixed format so Texas consumers can compare plans on identical criteria.

Where does the EFL hide the real rate during paid hours?

The daytime energy charge appears in the pricing section as a per-kWh figure; as of mid-2026 plan filings reviewed by SaveOnEnergy, the typical range on Texas free nights plans is $0.18 to $0.25 per kWh. It is not hidden, but it is overshadowed by the bold average price at 1,000 kWh headline, which already embeds an assumed share of free window usage.

How do I calculate my actual monthly cost from the EFL?

Multiply monthly kWh by the daytime usage share, multiply that by the daytime energy charge plus the TDU per-kWh delivery rate, add the TDU monthly fixed charge and any base or minimum usage fee, then subtract any earned bill credit. Compare the result to the same calculation on a fixed rate EFL.

What are the most common hidden fees on a free nights EFL?

Monthly base charges, minimum usage fees triggered below a threshold, bill credit thresholds that vanish in lower usage months, and early termination fees of 150 to 295 dollars (as of recent filings).

How does the EFL disclose the start and end time of free hours?

The EFL spells out the exact start time, end time, time zone (Central Time in Texas), and days of the week the free window applies. The Terms of Service must match.

What rules does the PUCT enforce on EFL disclosure?

PUCT Substantive Rule 25.475 sets the EFL format, the average price calculation, the two-page maximum, the minimum font size, the unique-per-product requirement, and the obligation to issue a new EFL for any plan change. The Customer Protection Division investigates complaints at 1-888-782-8477.

How does VIP Energy Service compare EFLs for you?

We rebuild the average price calculation against the household's actual twelve month usage, flag every base charge and minimum usage fee, and hand back a one page side by side comparison of the free nights plan, a fixed rate plan, and a free weekends plan, with an honest recommendation.

Get the most value from your solar investment with Texas' best buyback options

Making Sense of Solar in Texas

If you're a Texas homeowner with solar panels or considering installation, finding the right electricity plan is critical to your investment's success. The Texas open energy market offers numerous options, but understanding the differences in buyback rates, contract terms, and provider reliability is essential to maximizing your returns.

Texas continues to lead in renewable energy adoption, currently ranking second nationwide for solar power capacity with over 20,000 megawatts installed as of 2025.

According to the Solar Energy Industries Association (SEIA), solar manufacturing capacity in Texas saw remarkable growth throughout 2024, with the state now boasting 8.6 GW of production capacity SEIA, Solar Market Insight Report 2024 Year in Review.

For solar panel owners, this industry growth translates to more competitive solar electricity plans with favorable buyback rates and terms. This guide will help you navigate the options to select the plan that delivers optimal value for your specific situation.

Understanding Solar Electricity Plans

Solar electricity plans are specialized energy products designed specifically for homeowners with solar panel systems. Unlike standard electricity plans, these include provisions for purchasing excess energy your system generates and returns to the grid.

Key components that distinguish solar electricity plans:

• Buyback Provisions: Structured methods for compensating you for excess electricity your panels produce
• Specialized Billing: Systems that account for both consumption and production in a single bill
• Dual-direction Metering: Equipment that accurately measures both imported and exported electricity
• Specific Terms: Clear guidelines regarding buyback rates, credit rollovers, and production limits

Most Texas solar homes maintain their grid connection, using a solar electricity plan for backup power during low production periods and to earn credits when generation exceeds household needs.

The Public Utility Commission of Texas (PUCT) has established comprehensive interconnection standards for distributed generation systems, ensuring safe and reliable grid connections PUCT Substantive Rules §25.211 and §25.212.

Texas Solar Plan Options

The Texas market offers several distinct types of solar electricity plans, each with specific advantages depending on your situation:

competitive Buyback Solar Plans

These premium plans compensate you at the same rate for electricity exported to the grid as what you pay for electricity imported from the grid.

Advantages:

• Maximum value for excess solar production
• Straightforward billing and credit calculations
• Typically include credit rollover provisions

Important Considerations:

• Often carry higher monthly service fees
• Generally require longer contract commitments
• May include system size limitations

Market-Rate Solar Plans

These plans base compensation on the wholesale electricity market price at the time you export power to the grid.

Advantages:

• Potential for substantial returns during peak demand periods
• No artificial caps on buyback rates during market spikes
• Generally have lower monthly fees

Important Considerations:

• Compensation rates fluctuate significantly
• Lower average rates compared to competitive plans
• Requires more active monitoring to maximize benefits

Time-of-Use Solar Plans

These specialized plans offer variable rates for electricity consumption and production based on the time of day.

Advantages:

• Premium buyback rates during peak demand hours
• Rewards strategic energy usage patterns
• Can deliver superior returns for well-optimized systems

Important Considerations:

• Requires active management of household energy usage
• More complex billing structures
• May necessitate battery storage for optimal results

According to ERCOT's Combined Wind and Solar dashboard, solar generation peaks during midday hours when many time-of-use plans offer lower consumption rates ERCOT Combined Wind and Solar. This creates strategic opportunities for maximizing value with the right solar electricity plan.

Selecting the Optimal Solar Plan

Choosing the right solar electricity plan requires careful evaluation of your specific circumstances:

Step 1: Analyze Production and Consumption Patterns

Before evaluating plan options, gather comprehensive data on your typical solar production and household consumption patterns.

Essential metrics to track:

• Average monthly solar production (in kilowatt-hours)
• Average monthly household consumption (in kilowatt-hours)
• Production/consumption ratio by season
• Daily production and consumption patterns

The U.S. Energy Information Administration (EIA) reports that solar generation patterns in Texas are reshaping daily electricity supply profiles, with production peaking at midday U.S. Energy Information Administration. This timing significantly impacts optimal energy usage strategies.

Step 2: Assess Export Potential

The value proposition of various solar electricity plans largely depends on your typical export volume.

Factors influencing export potential:

• System size relative to household consumption
• Alignment between usage patterns and production periods
• Seasonal variations in production and consumption
• Presence of battery storage systems

Step 3: Compare Plan Features Comprehensively

When evaluating solar electricity plans, consider all aspects beyond just the buyback rate:

Critical comparison points:

• Import rate: Your cost per kilowatt-hour for grid electricity
• Export rate: Your compensation per kilowatt-hour for exported electricity
• Monthly fees: Base charges and recurring service fees
• Credit expiration: Terms regarding unused credit expiration
• Contract duration: Required commitment period
• System size parameters: Maximum solar system capacity allowed
• Net production policies: Any limitations on being a net producer

Step 4: Calculate Projected Savings

Use your production and consumption data to estimate actual savings under different solar electricity plans.

For a representative 10kW system in Dallas generating 14,000 kilowatt-hours annually with household consumption of 12,000 kilowatt-hours:

• Under a competitive buyback plan at $0.13/kWh: Approximately $260 in annual credits
• Under a wholesale rate plan averaging $0.03/kWh for exports: Approximately $60 in annual credits

The Houston Advanced Research Center (HARC) offers tools to help Texas residents understand solar economics, including their comprehensive Texas Solar Calculator available through the Clean Energy Hub Houston Advanced Research Center. These resources provide accurate estimates of potential savings based on your specific circumstances.

Premium Solar Buyback Features

Beyond choosing the right solar electricity plan, Texas homeowners with solar panels can generate additional savings by selling excess energy back to the grid. Learn the ins and outs in our complete guide to selling solar energy.

When comparing solar electricity plans in Texas, prioritize these features for maximum value:

Unlimited Credit Rollovers

The most advantageous solar power plans allow unused credits to roll over indefinitely, ensuring you retain the full value of your solar production.

No Export Limitations

Some plans restrict the quantity of excess electricity you can sell back or prohibit being a net producer over billing cycles. Plans without these restrictions offer substantially greater value for larger solar systems.

Guaranteed Minimum Buyback Rates

While market-rate plans can be beneficial, look for those with minimum buyback rate guarantees that provide protection during periods of low wholesale prices.

Flexible System Size Acceptance

Some providers restrict eligibility based on your solar system's capacity. The best plans accommodate systems of all sizes and allow for future expansion.

Transparent Contract Terms

Clear, comprehensive terms regarding buyback rates, credit calculations, and fee structures prevent unexpected costs and ensure fair compensation for your solar production.

Maximizing Plan Benefits

Implement these strategies to optimize the value of your solar electricity plan:

Strategic Energy Usage Timing

Schedule energy-intensive activities (laundry, dishwashing, EV charging) during periods when your solar production exceeds household needs or when grid electricity rates are lowest.

Regular System Performance Monitoring

Consistently evaluate your solar system's performance to ensure optimal production and promptly address any issues that might reduce efficiency.

Detailed Billing Analysis

Carefully review electricity bills to verify proper credit for your solar production and identify opportunities for usage optimization.

Consider Energy Storage Solutions

Adding battery storage can significantly enhance the value of certain solar electricity plans by enabling you to:

• Store excess production rather than exporting at unfavorable rates
• Utilize stored energy during peak price periods
• Maintain power during grid outages

The Electric Reliability Council of Texas (ERCOT) has established a Battery Energy Storage Task Force to facilitate integration of battery storage resources into the Texas grid, recognizing their increasing importance in energy management ERCOT Battery Energy Storage Task Force. This focus on storage integration highlights the growing role batteries will play in maximizing solar electricity plan benefits.

Annual Plan Evaluation

The Texas electricity market evolves continuously. Review your solar plan annually and evaluate alternatives to ensure you're still receiving optimal value.

Texas Success Stories

Common Questions Answered

How do solar electricity plans work in Texas?

Solar electricity plans in Texas are specialized energy products for homeowners with solar panels. These plans include provisions for purchasing excess electricity your system generates and delivers to the grid, typically as bill credits. When your panels produce more electricity than your home consumes, the surplus flows to the grid, and you receive credit based on your plan's specific buyback rate.

The Texas Public Utility Regulatory Act established that "a customer is entitled to have access to on-site distributed generation," which created the foundation for today's solar electricity plans Texas Interconnection Standards. The technical requirements for grid connection are defined in PUCT Substantive Rules §25.211 and §25.212.

What distinguishes net metering from solar buyback?

Net metering is a specific type of solar buyback program where you're credited at full retail rate (competitive) for excess electricity. While Texas doesn't mandate net metering, many providers offer similar benefits through solar buyback plans. The key difference is that buyback rates in Texas vary by provider and may be lower than the retail rate you pay for electricity.

Can I sell more electricity than I use with solar electricity plans?

It depends on your provider and specific plan. Some solar electricity plans allow unlimited net production, while others cap buyback credits at your total consumption level. Plans that restrict net production typically won't compensate you for generating more electricity than you consume over a billing cycle.

What determines my potential savings with a solar electricity plan?

Savings vary based on your solar system size, energy consumption patterns, and chosen plan. Most Texas homeowners with appropriately sized systems and favorable solar plans see 50-90% reductions in annual electricity costs. Factors affecting savings include buyback rates, monthly fees, and your ability to optimize usage to maximize solar production benefits.

What happens to my solar credits if I change providers?

Most solar electricity credits don't transfer between providers. If you switch companies, you typically forfeit any accumulated credits. Before changing providers, use or cash out any accumulated credits if possible, and carefully compare the long-term value of your current credits versus potential savings with a new provider.

Conclusion

Selecting the right solar electricity plan is essential for maximizing your solar investment in Texas. The optimal plan for your situation depends on your specific energy production and consumption patterns, along with your priorities regarding predictability, guaranteed savings, or maximum return potential.

As Texas continues its leadership in renewable energy adoption, solar electricity plans will continue to evolve, likely offering increasingly favorable terms for solar homeowners. By understanding the key components of these plans and strategically selecting the option that aligns with your specific needs, you can substantially enhance your solar system's financial benefits while contributing to a more sustainable energy future.
