Should Texans Lock In a Fixed-Rate Electricity Plan This August? Here Is What the Forward Price Curve Says

If your goal is a predictable bill through the winter, August 2026 is a reasonable time to lock a fixed-rate plan in Texas. The forward price curve for winter 2026-2027 is not screaming an emergency, but it is pricing in real risk from data-center load growth and Gulf Coast LNG demand, and the cheapest teaser rates on Power to Choose right now are exposed to that curve. A short-to-mid term fixed plan protects the winter side of your bill without over-committing.

Key takeaways

What the ERCOT forward price curve actually tells you

The forward price curve is the market's live estimate of what wholesale power will cost in each future delivery month. Retailers use it as the raw ingredient in every fixed-rate plan they write, then add TDU delivery charges, ancillary costs, and a margin. When the curve for December 2026 through February 2027 sits meaningfully above the summer curve, that is the market pricing in winter risk, and fixed rates reflect it before the weather does.

Three signals matter right now. Load growth is real: ERCOT's April 2026 preliminary long-term forecast projects about 367,790 MW of demand in the ERCOT region by 2032, largely driven by data centers and industrial expansion. Gas fundamentals have softened slightly: EIA's August 11, 2026 Short-Term Energy Outlook trimmed the Henry Hub price outlook by 2% for 2026 and 4% for 2027 compared to earlier forecasts. And near-term wholesale prices have not been as violent as headlines suggest, with Doug Lewin, a Texas energy analyst whose public profile lists energy strategy work in Texas at Google, noting that during the July 2026 heat event wholesale prices stayed "well below the cap (95% below at times)."

Two of those signals argue for patience. One argues for prudence. That is why the forward curve for winter 2026-2027 is up but not extreme, and why the August lock question is a judgment call rather than an obvious yes or no. If you want to see how these plan structures interact with your actual bill, our guide on how to read your Texas electricity bill walks through every line item.

Where fixed and variable rates sit on Power to Choose this August

As of August 2026, Texas residential retail listings show a wide spread across term lengths and plan types.

Two things jump out from those numbers. The spread between the lowest teaser rate and the highest plan on the same market page is often 10 cents per kWh or more. And 36-month plans are priced above 24-month plans, which is the forward curve talking: the market expects the second half of the decade to cost more, not less. Actual rates vary by ZIP code, TDU, plan, and usage level. Energy facts label available on every Ambit plan, showing the all-in cents-per-kWh at 500, 1,000, and 2,000 kWh so you can compare apples to apples. Our guide to picking the right rate plan in 2026 walks you through the EFL and the five plan tricks to spot before you sign.

Variable-rate plans, by contrast, are a monthly bet on the wholesale market. They can undercut fixed pricing during mild months, and they can spike hard in a cold snap. There is no regulatory cap on how much a variable rate can move month to month in Texas, and there is no reset button on the bill once the move happens.

Four forces pulling on the 2026-2027 Texas forward curve

Natural gas fundamentals and LNG exports

Gas sets the marginal price of power in ERCOT most hours of the year, so gas is where the curve starts. According to Naser Ameen, a principal contributor at the U.S. Energy Information Administration, "We expect prices to rise from $3.52 per million British thermal units (MMBtu) in 2025 to $4.31/MMBtu in 2026 and to $4.38/MMBtu in 2027." Rising Haynesville production is being pulled toward Gulf Coast LNG terminals, which keeps upward pressure on the domestic gas market even as U.S. production hits record highs.

ERCOT reserve margin and data-center load

ERCOT's minimum reserve-margin target is 13.75% of peak demand, and that target gets harder to hit as load growth accelerates. ERCOT President and CEO Pablo Vegas confirmed in April 2026 that "the current forecast projects approximately 367,790 MW of demand in the ERCOT Region by 2032," a step-change driven largely by data centers. For more on how the ERCOT grid and the retail market fit together, see our explainer on how Texas deregulated electricity works.

Not everyone thinks the load will arrive on that timeline. Joshua D. Rhodes, a research scientist at the University of Texas at Austin, told the Texas Tribune that "I just don't believe that that much new load can come online that fast, so I don't think things are as bad as the report would indicate." That skepticism matters because the price curve moves with expected load, and if the market reprices the timeline, the curve will follow.

New solar and battery storage coming online

Supply growth is the counterweight. S&P Global's July 2026 grid outlook identified nearly 28 GW of planned ERCOT additions, including 13.3 GW of solar. More solar tends to compress midday prices, and more storage helps flatten evening peaks. Neither eliminates winter or extreme-weather volatility, but both should moderate the daytime average through 2027.

TDU delivery charges you cannot lock away

Here is the part homeowners often miss. The energy portion of your bill is what a fixed-rate plan locks. The TDU delivery charges from Oncor, CenterPoint, AEP Texas, or TNMP are separate, and they change on their own regulatory schedule. Locking a fixed energy rate protects the biggest, most volatile line on the bill, but it does not freeze every line. Our breakdown of TDU delivery charges shows how the wires side of your bill is set separately from the energy side.

The August 2026 lock-in decision framework

Walk your household through these five filters before you sign anything.

  1. Bill certainty first. If you would rather know your rate for the next 12 to 24 months than try to time a market bottom, a fixed rate is the correct choice regardless of where the curve is.
  2. Usage size. Larger homes with winter heating loads have more to lose from a February variable-rate spike, and the bigger your usage the more insurance a fixed rate buys you.
  3. Contract-term appetite. A 12 or 24-month fixed plan captures winter risk without committing you to a 36-month curve that is already priced higher, so longer is not automatically better.
  4. Winter risk tolerance. If a single-month bill three times your normal would be a real problem for your household budget, a variable plan is not the right instrument for you right now.
  5. EFL fit. Compare the Electricity Facts Label at the usage level you actually consume, because a low-headline plan is often designed around 1,000 kWh and your true cost at 500 or 2,000 kWh can be very different.

If four of five filters point to lock, lock. If two or fewer point to lock, stay put and revisit in October, before the first cold front.

What happens if you wait?

Waiting is a defensible strategy for households that use less power, have flexible budgets, and can move quickly if the market shifts. The August 2026 STEO trend of slightly lower gas prices means the downside case for waiting is real, not fantasy. But two things narrow that upside. Retailers reprice fixed plans continuously, so a small drop in the wholesale curve rarely translates into a huge drop in the retail rate you actually see. And waiting exposes you to the winter shoulder, which is where most Texas rate regret lives.

There is also a version of waiting that is really procrastination. Month-to-month customers on a holdover product typically pay the highest rate on the page. Nearly $480 a year in overpayments shows up when Texas households let a fixed term roll off without shopping the market. If your current plan already expired, waiting is not neutral. It is expensive.

Frequently asked questions

Should I lock in a fixed-rate electricity plan in August 2026?

Yes, if your priority is bill certainty and you are comfortable with a 12 to 24-month term. The forward curve for winter 2026-2027 is not extreme, but it is up, and locking removes the biggest variable on your bill.

Is a variable-rate plan actually cheaper right now?

Sometimes, for a month or two during mild weather. A variable rate has no cap and no notice period, so a mild fall can flip to a cold-front spike with no cushion for your household.

How much do fixed rates in Texas cost this August?

Fixed rates run roughly 6.0 to 11.8 cents per kWh on 12-month plans, 6.8 to 7.6 cents on 24-month plans, and 13.1 to 14.0 cents on 36-month plans, per Power to Choose listings as of August 2026. Your ZIP code and usage level make a real difference to the number you actually pay.

What does the ERCOT forward price curve say about winter 2026-2027?

The winter curve is priced above the summer curve right now, reflecting expected load growth, LNG-driven gas demand, and the reserve-margin picture ERCOT laid out in its April 2026 long-term forecast.

Will winter 2026-2027 be more expensive than summer 2026?

The forward market is priced that way today, though a mild winter can pull the realized price back. Under EIA's high-demand scenario, 2027 ERCOT wholesale prices could rise about 78.9% versus a $47.39 per MWh baseline.

How much can a variable-rate plan change from month to month in Texas?

There is no regulatory cap on how much a variable rate can move between billing cycles in the deregulated Texas market. During a cold snap, wholesale prices can multiply several times over, and a variable retail plan passes that entire move through to your bill with no cushion.

Should I choose a shorter fixed term now, or lock in a longer one?

For most Texas households, a 12 or 24-month fixed term is the sweet spot. Longer 36-month terms tend to carry a premium because they push you further out the forward curve, which is priced higher for later years.

If your Texas household or small business electric bill spiked after the July 2026 heat wave, four assistance programs will actually pay part of it: CEAP (Texas's state energy-assistance program), Texas Utility Help, 2-1-1 Texas referrals, and Salvation Army utility grants. Households at or below 150% of the federal poverty guideline qualify for most of them, and CEAP alone can cover a large share of a summer bill.

This post is written for Ambit Brand customers, which is Texas households and small businesses shopping for retail electricity plans on the deregulated ERCOT market. It is not intended for the Ambit VIP consultant channel. Content covers the four Texas assistance programs that actually pay part of an electric bill, who qualifies in 2026, and what to do first when a heat-wave bill is bigger than the paycheck.

Key Takeaways

Why Are Texas Electric Bills So High This Summer?

Summer bills in Texas rise for a simple reason: cooling a Texas home in July and August takes far more electricity than in mild months. The average Texas household uses roughly twice as many kilowatt-hours in summer as in spring, and the July 2026 heat wave pushed ERCOT into repeated peak-demand events and conservation notices. Higher usage on the same rate produces a bigger bill. Higher usage on a variable rate produces a much bigger one.

The good news is that Texas has a real safety net for households whose bill has outrun their paycheck. The four programs below are the ones that actually pay money toward the electric bill, not just referrals or tip sheets.

What Are the 4 Assistance Programs That Actually Help Texans?

Here is the side-by-side view, in one place, so you can pick the right door to knock on first.

Program Who runs it What it covers Income limit How to apply
CEAP (Texas's state energy-assistance program) TDHCA, delivered through local community action agencies Bill payment plus crisis assistance during extreme weather. Up to $12,600 heating and cooling and $1,800 crisis per year 150% of Federal Poverty Guidelines Call 877-541-7905 or apply through your local CEAP provider
Texas Utility Help TDHCA statewide portal for past-due bills Past-due electric, gas, and water bills Program-set income cap (verify at application) Apply online at TexasUtilityHelp.com or call 855-566-2057
2-1-1 Texas Texas Health and Human Services referral network Warm handoff to local nonprofits, faith-based groups, and emergency utility grants Varies by referred program Dial 2-1-1 (free, 24/7) or visit 211texas.org
Salvation Army utility rent assistance The Salvation Army Texas Division and partner agencies Emergency, limited-fund grants toward utility bills Case-by-case, prioritized by need Contact your local Salvation Army office or dial 2-1-1 for the nearest partner

Program 1: CEAP (Texas's State Energy-Assistance Program)

CEAP is Texas's LIHEAP-funded bill-payment program, administered by the Texas Department of Housing and Community Affairs (TDHCA) and delivered through local community action agencies. According to the TDHCA CEAP program page (2026), the program is designed to help low-income Texans with their immediate energy needs and their energy costs over the year.

The numbers are the reason to start here. According to the LIHEAP Clearinghouse Texas profile (2026), Texas's LIHEAP funding for fiscal year 2026 is $181,183,241, the maximum household benefit is $12,600 for heating and cooling, and the maximum crisis benefit is $1,800. According to the NuWatt Energy Texas income-eligible programs guide (2026), a typical CEAP bill-assistance award falls between $300 and $1,500 depending on household size, income, and how severe the crisis is.

Eligibility is straightforward. CEAP is open to households at or below 150% of the federal poverty guideline, which the NuWatt guide (2026) lists as roughly $45,600 in annual income for a family of four in 2026. Renters qualify if they are responsible for the electric account.

To apply, call 877-541-7905 or find your local CEAP provider through the TDHCA website. Most agencies ask for a photo ID, proof of income for every adult in the household, a recent electric bill with the account number, and proof of residency. Processing typically takes a few business days to about two weeks, per the Texas utility-help resource summarized in the Powerwizard 2026 guide.

Program 2: Texas Utility Help

Texas Utility Help is a separate TDHCA-run portal built specifically for past-due utility bills. Where CEAP focuses on the household's yearly energy costs, Texas Utility Help is aimed squarely at the shut-off risk that follows a big summer bill.

Applications go through TexasUtilityHelp.com or the call center at 855-566-2057, and the program can cover past-due electric, gas, and water. If your bill just arrived and it is much higher than usual, this is often the fastest state-level path to real relief.

Program 3: 2-1-1 Texas

2-1-1 Texas is the state's free, 24/7 referral line. It is not a bill-payment program by itself, but it is the fastest way to find the local nonprofit, church, or partner agency near you that does write checks. According to the PUCT consumer-help page (2026), 2-1-1 is the number PUCT itself directs Texans to call when they cannot pay their electric bill. Dial 2-1-1 from any phone, or visit 211texas.org.

Use 2-1-1 when CEAP and Texas Utility Help are backed up, or when you need something the state programs will not cover, like a partial-month deposit to keep service on.

Program 4: Salvation Army and Community Action Agencies

The Salvation Army offers emergency utility grants through its local Texas offices, and it partners with community action agencies across the state. According to the Salvation Army 2025 annual report, the organization provided financial assistance to 1,575,098 households nationwide that year.

Funds are limited and awarded case by case, but Salvation Army help is often the last-mile grant that closes the gap between your CEAP award and your actual balance. The fastest path is to dial 2-1-1 and ask for the nearest Salvation Army utility program.

What Should I Do First If I Already Have a Disconnection Notice?

Call your electric provider today, before you do anything else. Every Texas retail electric provider is required to offer some form of deferred payment plan on request, and most will grant a short payment extension over the phone.

There is also a legal safety net during heat waves. According to the PUCT 2026 summer consumer bulletin, electric disconnections for nonpayment are prohibited during declared extreme-weather emergencies, including extreme heat. That is a floor, not a permission slip. Interest and balance still accrue, and disconnection risk returns once the emergency lifts. Get on a deferred plan and apply for CEAP or Texas Utility Help while the extreme-heat protection is in effect.

Ambit Energy customers who are worried about a summer bill spike can also call the Ambit customer care line printed on the bill to ask about payment arrangements and confirm the account is in good standing before applying to a program.

The $166 Million 2026 Boost: What Is Changing and When

On June 8, 2026, Governor Greg Abbott announced $166 million in new energy-assistance funding for low-income Texans, administered by TDHCA and available for utility bills and efficient heating, cooling, and refrigeration equipment. According to the TDHCA news release (2026), the funds are scheduled to begin January 1, 2027.

That timing matters. The $166 million will not reach households in time for August or September 2026 bills. For this summer, CEAP, Texas Utility Help, 2-1-1, and Salvation Army are still the four doors to knock on. When the new money opens in January 2027, expect wait times to drop and per-household awards to rise for a period.

The 24-Hour Bill Relief Playbook

Here is the sequence I would run through, in order, if a heat-wave bill just arrived and you cannot pay all of it.

  1. Call your electric provider today. Ask for a payment extension, a deferred payment plan, or both. Get the confirmation number in writing.
  2. Dial 2-1-1 Texas. Ask for CEAP intake and for the nearest Salvation Army or community action agency that helps with utility bills.
  3. Apply to CEAP at 877-541-7905 AND to Texas Utility Help at 855-566-2057 or TexasUtilityHelp.com. These are separate programs, and applying to both maximizes what actually gets paid.
  4. Reset the plan for next summer. Look at your kWh usage from July, then choose a plan built for high-usage Texas summers so this does not repeat.

Do all four in a day. That is the difference between a disconnection notice and a manageable payment plan.

Frequently Asked Questions

Am I eligible for CEAP, and what income counts?

CEAP eligibility is set at or below 150% of the federal poverty guideline, per the TDHCA CEAP program guidance (2026). Household income includes wages, self-employment income, Social Security, unemployment, and most other cash income for every adult member. The NuWatt Energy guide (2026) lists 150% FPL at roughly $45,600 for a family of four in 2026.

How long does CEAP processing take?

Processing time varies by local agency, but the Powerwizard Texas bill-help guide reports a typical range of a few business days to about two weeks. Applications marked as a crisis (imminent disconnection or broken cooling equipment) are usually expedited.

Do renters qualify?

Yes. Renters qualify if they are responsible for the electric account and meet the income and residency requirements. This is confirmed by the Texas Law Help utility-assistance article (2026).

What documents do I need to apply?

Most agencies ask for a government-issued photo ID, proof of income for every adult in the household (recent pay stubs, benefits letters, or tax returns), a recent electric bill with the account number and balance, and proof of residency. Some agencies also request medical documentation if a household member has a life-support need.

Can my power be shut off during a Texas heat wave?

Not during a declared extreme-weather emergency. According to the PUCT 2026 summer consumer bulletin, electric disconnections for nonpayment are prohibited during declared extreme-heat events. The protection is temporary, so use the window to apply for CEAP or Texas Utility Help and lock in a deferred plan.

What if my income is normally above the limit but this bill is crushing me?

Talk to your provider about a deferred payment plan, then call 2-1-1. Community action agencies and Salvation Army partners often have discretionary emergency funds that are not tied to the 150% FPL line and can bridge a one-time hardship.

TL;DR: A June 2026 Retail Energy Revealed report found Texas residential retail-choice customers overpaid about $4 billion in 2024 (roughly $480 per household) versus regulated default service. The cause is plan design, not usage. Five recurring tricks account for most of the gap: teaser rates, bill-credit thresholds, tiered pricing, silent auto-renewal to variable, and opaque free-nights plans. Six numbers on every Electricity Facts Label (EFL) catch every one of them: the average price at 500, 1000, and 2000 kWh, base charge, TDU delivery charges, and any minimum-usage fee or bill credit. This guide, using the Rule of 5-and-6 framework, walks through each trick and how to spot it before you sign.

A new report is putting a dollar figure on something Texas power shoppers have suspected for years: retail electricity plans are engineered to look cheap on the shelf and quietly cost more once the meter starts running.

The June 8, 2026 Retail Energy Revealed report found that Texas residential retail-choice customers paid about $4 billion more in 2024 than regulated default service would have cost, and more than $48 billion extra since deregulation began in the early 2000s. That works out to roughly $480 a year for a typical household. The findings were amplified on July 21, 2026 by the Dallas Morning News, Texas Standard, and a Forbes column by University of Houston energy economist Ed Hirs, all pointing at the same culprit: plan design, not usage.

At Ambit, we have been selling straightforward retail electricity in Texas since 2006, so this is our lane. Here is the Rule of 5-and-6 framework: the 5 plan tricks that drive most of the overpayment, and the 6 numbers on the Electricity Facts Label (EFL) that catch every one of them.

What Did the Retail Energy Revealed Report Actually Say?

The Retail Energy Revealed analysis, first reported by EnergyChoiceMatters on June 8, 2026, compared what residential retail-choice customers across the country actually paid to what regulated default service would have cost over the same years. Texas, the largest deregulated market in the United States, contributed the biggest slice of the $4 billion 2024 gap.

Ed Hirs, writing in Forbes on July 8, 2026, framed the same numbers as an ongoing consumer-protection problem: providers compete hard for you during a short promotional window, then monetize the relationship through renewal terms, credits tied to a narrow usage band, and rate structures that are hard to compare on a single dollar figure.

None of this is illegal. All of it is disclosed on the plan's Electricity Facts Label. But the tricks work because the average Texas shopper reads the marketing headline, not the EFL.

What Is the Teaser Rate Trick?

The rate you see on the ad is the rate for the first billing cycle or the first few months. After the promo ends, the price steps up, sometimes materially.

QuickElectricity and the Dallas Morning News both flag this as the single most common plan-design tactic in Texas. A plan advertised at 10.9 cents per kWh may be a 12-month contract that averages closer to 14 cents per kWh once the introductory period ends.

How to catch it: open the EFL. The "Average Price per kWh" figures at 500, 1000, and 2000 kWh are the contract-length averages, not the promo price. If those three numbers are noticeably higher than the marketing headline, you are looking at a teaser.

How Do Bill-Credit Thresholds Inflate Your Bill?

This is the most expensive trap of the five. The plan gives you a fixed dollar bill credit only if your monthly usage falls inside a narrow window, often 1000 to 2000 kWh. Use 999 kWh in a mild April, and the credit disappears. ElectricRates and Texas Electricity Ratings both note this can effectively double your rate in months where you miss the threshold.

Bill-credit plans reward one usage pattern and punish every other one. A family that goes on vacation for a week, a small business that closes for a holiday, or a household running efficient appliances all get penalized.

How to catch it: the EFL will list a "Minimum Usage Fee" or a bill credit line under "Other Key Terms and Questions." If either exists, calculate your effective rate at 500 kWh (a light month) and 750 kWh (a shoulder month), not just at the sweet spot.

What Is Tiered or Usage-Benchmark Pricing?

Similar to bill credits, but structured as different per-kWh rates at different usage bands. The plan quotes 9 cents per kWh at 1000 kWh, then 13 cents at 500 kWh and 11 cents at 2000 kWh. Looks attractive at exactly one benchmark, expensive everywhere else.

ElectricRates recommends always calculating your effective rate at your own historical monthly usage rather than at the benchmark the plan is designed around.

How to catch it: if the three "Average Price per kWh" numbers on the EFL vary by more than 1.5 cents across the 500, 1000, and 2000 kWh columns, the plan has tiered pricing. Pick the column closest to your actual bill.

How Does Silent Auto-Renewal to a Variable Rate Cost You?

Your fixed-rate contract ends. If you do not re-shop, most providers roll you onto a month-to-month variable plan at a materially higher price. The Dallas Morning News notes this as one of the main levers behind the $480 annual overpayment figure, because plenty of Texans forget the renewal date and stay on the variable rate for months.

Variable rates are legitimate in the right context (Ambit's own Lone Star Flex is a no-contract month-to-month plan for people who want that flexibility), but a variable-rate auto-renewal from a contract you thought was fixed is usually the most expensive rate the provider offers.

How to catch it: the EFL and the Terms of Service both disclose renewal treatment. Look for "Renewal Type" on the Terms of Service. If it says the plan renews to a "month-to-month variable rate," calendar the contract end date now and plan to re-shop 30 days before it hits.

When Do Free Nights or Free Weekends Plans Actually Cost More?

Time-of-use plans that give away a chunk of hours (nights, weekends, sometimes both) are excellent for the right household and expensive for the wrong one. The catch is that the on-peak rate that funds the free window is often 3 to 5 cents per kWh above a comparable fixed plan.

ElectricRates puts a rule of thumb on it: unless more than about 30 to 40 percent of your usage falls inside the free window, a straight fixed-rate plan is cheaper. A household that runs the dishwasher and laundry after 8 PM, charges an electric vehicle overnight, or runs a pool pump on a night schedule can win. A household that mostly cools an empty house during the day and cooks dinner at 6 PM usually loses.

Ambit's Free and Clear Nights is a genuine option in this category with published on-peak and off-peak windows, but even a good time-of-use plan is the wrong tool if your usage does not fit the window.

How to catch it: the EFL will show two "Energy Charge" lines instead of one, one for the free window and one for the paid window. Multiply your actual on-peak kWh (roughly 60 to 70 percent of usage for most Texas households) by the paid rate to see what you would really pay.

Which 6 EFL Numbers Catch Every Trick?

Every Texas retail electricity plan is required to publish an Electricity Facts Label. You can find it on Power to Choose or on the provider's own site. Six numbers on that label neutralize all 5 tricks:

# Number on the EFL Where to find it What it catches
1 Average Price per kWh at 500 kWh Top of EFL, pricing box Teaser rates, tiered pricing
2 Average Price per kWh at 1000 kWh Top of EFL, pricing box Baseline for typical household
3 Average Price per kWh at 2000 kWh Top of EFL, pricing box Heavy-usage months, bill-credit collapse
4 Base Charge Pricing section, flat monthly fee Hidden fixed cost that raises low-use bills
5 TDU Delivery Charges Pricing section, pass-through wires cost Confirms Oncor, CenterPoint, AEP, or TNMP is disclosed
6 Minimum Usage Fee or Bill Credit Other Key Terms and Questions Bill-credit thresholds and usage-cliff traps

If those three "Average Price" numbers are close to each other, the plan is straight per-kWh pricing with no hidden usage cliff. If they vary widely, the plan is a threshold play. That single test filters out four of the five tricks.

Where Ambit Fits

We have been selling retail electricity to Texas households and small businesses since 2006, so we have watched every one of these tactics enter and exit the market. Our plans are built to survive the EFL test:

We publish the EFL for every plan, we do not price to a bill-credit threshold, and we send renewal notices in advance so nothing rolls silently to a higher variable rate.

Bottom Line for August 2026 Shoppers

The $480 gap the Retail Energy Revealed report identified is a plan-design problem, not a rate-market problem. Every one of the 5 tricks above is disclosed on the EFL before you sign. Read the label. Calculate at your actual monthly usage, not the benchmark. Calendar your renewal date. Prefer straight per-kWh pricing unless a time-of-use plan genuinely fits your household.

If you would like someone to review a Lone Star Classic quote for your ZIP code, we can gladly assist you with that as well. You can request a quote and we will retrieve your EFL to compare.

Frequently Asked Questions

What is an Electricity Facts Label (EFL)?

This is one page document provided by Texas retail electricity providers for each plan. It includes the average price for 500, 1000, and 2000 kWh, the base charge, TDU delivery pass-through, length of the contract, renewal treatment, percentage of renewable energy, and the minimum usage fee or a bill credit. It is available for each plan on the provider's site or on Power to Choose.

What is a bill-credit threshold, and why is it a trap?

A bill-credit plan provides a fixed dollar amount as a credit only when your monthly usage falls within a specified range (typically, 1000 to 2000 kWh). If your usage is lower than that range, you will lose the credit. This means your rates may double during that month. Texas Electricity Ratings and ElectricRates have both cited this as the most costly tactic when designing electricity plans for Texas.

When does a free nights or free weekends plan actually make sense?

As a rule of thumb, you usually need more than 30 to 40 percent of your monthly usage to be free in order for a time-of-use plan to offer better value than a straight, fixed-rate plan of equivalent quality. Households doing dishwashing, laundry, EV charging, or pool pumping at night stand to benefit; those who predominantly cool an unoccupied house during the day do not.

How often should I re-shop my electricity plan?

Mark your contract end date on the calendar, and aim to re-shop around 30 days ahead of it. Most fixed-rate contracts in Texas auto-renew to a month-to-month variance which tends to be the highest price offered by the provider. The Dallas Morning News cites auto-renewal as a key contributor to the $480 annual overpayment.

Which TDU serves my ZIP code?

Texas is served by four regulated TDUs (Transmission and Distribution Utilities). For the majority of the DFW metroplex, it is Oncor. For Houston and the coastal areas around it, it is CenterPoint. AEP Texas serves the Rio Grande Valley, South Texas, and around Corpus Christi, while TNMP serves a mix of North, Central, and Gulf Coast areas. The TDU is a fixed pass-through charge listed on every EFL, and is the same across providers within your ZIP code.

Is the $480 overpayment figure applicable to my home?

This figure represents an average in the Texas market, so your actual gap may vary based on your current plan, usage pattern, and how long you have been on your current contract. A household that is stuck on a variable rate after an unnoticed auto-renewal will be well above the average. A household that reads the EFL and re-shops annually will be well below it.

On July 13, 2026, ERCOT asked Texans to voluntarily conserve energy from 2 to 8 pm as summer heat pushed the grid toward record demand. The appeal does not affect your per-kWh rate. What it does show is a real gap in monthly outcomes across the three main retail plan structures in Texas: fixed, free-nights, and variable. If you are on the wrong one, this summer's string of conservation events can cost you real money by the time your August statement lands.

Key Takeaways

What Did July 13, 2026 Actually Bring?

The Electric Reliability Council of Texas issued a Voluntary Conservation Notice for the ERCOT interconnection, which serves roughly 90% of the Texas electric load. The grid operator asked Texans to voluntarily reduce electricity usage during the late afternoon and early evening, when summer air-conditioning load is at its highest. Oncor, the transmission and distribution utility that serves 13 million Texans across North and West Texas, echoed the request and asked residential and business customers to reduce electricity use between 2 and 7 pm.

A Voluntary Conservation Notice does not cut power to your home. Your lights stay on and your bill is not charged extra because of the notice itself. What the notice signals is that ERCOT's projected reserve margin, the cushion between generation supply and demand, was tight enough that voluntary conservation could keep the grid out of emergency operations.

What Is a Conservation Appeal, and How Is It Different From an Energy Emergency Alert?

A Voluntary Conservation Notice, also called a Conservation Appeal, is a request. An Energy Emergency Alert is an operating condition. Understanding the difference is the difference between adjusting your thermostat and losing air conditioning to a controlled outage.

ERCOT defines a Conservation Appeal as an elevated request for Texans to reduce their energy use during peak demand periods when there is a potential to enter emergency operations due to lower reserves. Under ERCOT's protocols, the appeal is typically triggered when projected operating reserves are forecast to fall below 2,300 MW for 30 minutes or more.

An Energy Emergency Alert is a very different event. According to ERCOT's operating protocols, the three levels work as follows:

According to Doug Lewin, president of Stoic Energy Consulting and one of the most-cited independent analysts of the Texas grid, the widening gap between summer peak forecasts and installed dispatchable capacity would produce exactly this pattern. Speaking with Energy Capital HTX in June 2026, Lewin noted that ERCOT's summer 2026 peak forecast of 92,000 MW would surpass the all-time record of 85,508 MW set on August 10, 2023, by nearly 8%.

According to Pablo Vegas, ERCOT's president and chief executive, data-center load growth and record-hot summers are pulling reserves tighter than at any time in ERCOT's history, in testimony to the Texas Senate Business and Commerce Committee this spring.

According to Michael Webber, professor of energy resources at the University of Texas at Austin, if just 10% of ERCOT households responded to a Conservation Appeal with a 3-degree thermostat setback, the aggregate load reduction would exceed 1,500 MW, more than the capacity of most single power plants.

Why Did ERCOT Call Conservation This Week?

The immediate cause of a Conservation Appeal is always the same math: forecast demand plus a weather-driven upside is running too close to forecast supply. Summer 2026 has stacked that math against reserves for weeks. On July 3, 2026, ERCOT set a new July peak demand record above 83,000 MW for the first time. Four days later, on July 7, 2026, ERCOT logged a sudden loss of generation totaling 685 MW at 19:35, with system frequency dipping to 59.958 Hz on a load of 79,425 MW, according to ERCOT's Operations Messages log.

Extreme heat is the accelerant. Air conditioning accounts for about 60% of summer residential load in Texas, and when overnight lows stay in the 80s across Houston, Dallas-Fort Worth, San Antonio, and Austin, air conditioners run 20% to 40% longer into the afternoon peak. ERCOT's preliminary Long-Term Load Forecast, filed with the Public Utility Commission of Texas on April 15, 2026, projects that summer 2026 peak load will fall in a range of 90,500 MW to 98,000 MW. The July 13 appeal is part of the pattern that forecast anticipated.

The Three-Plan Conservation Test: An Original Framework for Reading Your Plan in 60 Seconds

Not every retail plan responds the same way when ERCOT calls for conservation. To simplify how a conservation event actually flows through to your monthly bill, we developed an original framework we call The Three-Plan Conservation Test. This framework sorts every Texas plan on the market into one of three buckets, and each bucket reacts to a conservation week differently. Walk your own plan through the framework and you will know within 60 seconds whether the July 13 event helps you, hurts you, or leaves you neutral. This is our proprietary way of translating an ERCOT grid event into a household-bill answer.

Bucket 1: Fixed-Rate Plans (Lone Star Classic 24)

A fixed-rate plan holds your per-kWh energy charge unchanged for 24 months. Lone Star Classic 24 is the canonical example. When ERCOT calls a conservation appeal, the wholesale market often spikes 200% to 500% as scarcity pricing kicks in, but a fixed-rate customer sees 0% of that on the next statement. The rate on your Electricity Facts Label is the rate you pay, as of your plan's start date.

For households that value predictability, that is the point. You still benefit from conservation because using fewer kWh during peak lowers your usage, but the price component is 100% insulated. Plan details and rates subject to change; Subject to credit approval.

Bucket 2: Free Nights Plans (Free and Clear Nights)

Free and Clear Nights makes electricity used between 9 pm and 5:59 am free, 7 nights a week, for a full 9-hour overnight block. In exchange, daytime rates run higher than typical fixed rates, cited between 24.4 and 29.4 cents per kWh depending on term and TDU area, as of July 2026. Standard pricing disclaimers, including credit approval and Electricity Facts Label details, apply.

On a conservation-appeal day, a Free Nights household has the biggest actionable upside of the three buckets. Every kWh you can push out of the 2 to 8 pm window and into the after-9 pm free block compounds two ways: it saves the 24 to 29 cents you would have paid on the daytime rate, and it lands the same kWh in the free block at zero cost. Laundry, dishwashing, pool-pump cycles, and EV charging are the highest-leverage loads to move; a single Level-2 EV charge alone can consume 40 to 60 kWh.

Bucket 3: Variable-Rate Plans (Lone Star Flex)

Lone Star Flex is a variable, month-to-month plan with no cancellation fee. The flexibility is real, and for renters or short-term Texas residents that is often the right call. The trade-off is monthly pricing risk. When wholesale prices spike 200% to 500% during a string of conservation days, that spike can flow through to the next month's variable rate as a 15% to 40% jump on the base kWh price.

If your household is on a variable plan and July has already seen multiple ERCOT appeals, this is the summer to reprice into a fixed term before the August statement lands. Plan details and rates subject to change, and Subject to credit approval; rates and terms are not final until enrollment is confirmed.

The Four-Hour Peak Shift: What to Do Between 2 and 8 pm

ERCOT's residential guidance during a Voluntary Conservation Notice is straightforward, and Oncor's July 13 notice reinforced the same asks. The single window that matters is 2 to 8 pm, and inside it four moves do most of the work:

  1. Pre-cool, then hold. Drop your thermostat 2 to 3 degrees below your normal setting between noon and 2 pm, then raise it 2 to 3 degrees above normal from 2 to 8 pm. You get comfort on the front end and load reduction on the back end.
  2. Delay the big loads. Dishwasher, washer, dryer, and pool pump should run before 2 pm or after 8 pm. Modern dishwashers and washers have delay-start settings that make this a one-touch decision.
  3. Push EV charging to overnight. Schedule your EV charging to start at 9 pm or later. Most Level 2 chargers and vehicle apps support scheduled charging.
  4. Close blinds on west-facing windows. Solar heat gain through afternoon-facing windows can add 10% to 20% to your air-conditioning load during peak. A closed blind is a zero-cost shield.

Together, those four moves typically cut a peak-window household load 15% to 25% without touching comfort. Applied across the 11 million households in the ERCOT service area, even a 5% adoption rate would flatten 400 MW to 700 MW of peak demand.

When a Conservation Appeal Escalates to an Energy Emergency Alert

Most Voluntary Conservation Notices end quietly. The 2 to 8 pm window passes, demand relaxes as the sun sets, and reserves rebuild overnight. When they do escalate, though, the escalation is quick.

An appeal escalates to EEA Level 1 when actual operating reserves fall below 2,300 MW and are not expected to recover within 30 minutes. At that point ERCOT taps every available reserve program. If reserves fall further, EEA Level 2 layers on additional emergency measures. EEA Level 3, at reserves below 1,000 MW, is the stage that directs transmission utilities to begin controlled outages to prevent uncontrolled cascading failures.

Households cannot influence which stage the grid reaches, but the collective response to Voluntary Conservation Notices is one of the tools that keeps the grid from moving from stage to stage. That is the case ERCOT is making when a notice hits your phone through the Texas Advisory and Notification System (TXANS).

How to Check If Your Current Plan Penalizes You on Peak Days

Two documents tell you exactly where you stand. Both should be in your welcome packet or your online account.

  1. Your Electricity Facts Label (EFL). Check the pricing structure. If it lists a single rate expressed in cents per kWh with no time-of-use table, you are on a fixed-rate plan and a conservation event has no direct rate impact. If it shows a variable-rate clause or a month-to-month reset, you are exposed.
  2. Your Terms of Service. Look for a time-of-use rate structure. If the plan has a free block (like 9 pm to 5:59 am) or a discounted overnight block, you are on a shifting plan and every peak-window kWh you move is a compounding win.

If either document leaves you unclear, we can walk you through it. A quick review usually surfaces one of three outcomes: you are on the right plan and just need peak-shift habits, you are on the right structure but the term is up for renewal, or you are on a plan that is quietly penalizing you on days like July 13. Request a rate quote if you want a second set of eyes on your EFL.

Frequently Asked Questions

Does an ERCOT Conservation Appeal raise my electricity rate?
No. The appeal itself does not change your rate. If you are on a fixed-rate plan, the price you pay per kWh does not move. If you are on a variable-rate plan, wholesale price spikes during a conservation event can carry over to your next monthly rate reset as a 15% to 40% jump.

How long do Voluntary Conservation Notices usually last?
Most notices target the 2 to 8 pm peak window on a specific day. Some extend across several days during a heat wave. ERCOT publishes updates through the TXANS notification system and its Public Notices page.

Can ERCOT force my house to lose power during a Conservation Appeal?
No. A Voluntary Conservation Notice is a request only. Rotating outages only happen at EEA Level 3, which is triggered when actual operating reserves fall below 1,000 MW.

What is the single most impactful thing I can do at 2 pm on an appeal day?
Raise your thermostat 2 to 3 degrees above your normal setting after pre-cooling from noon to 2 pm. Air conditioning is about 60% of a Texas home's peak load, and this move alone typically delivers most of the household reduction ERCOT is asking for.

Are conservation appeals going to keep happening?
ERCOT's preliminary 2026 to 2032 Long-Term Load Forecast projects continued peak-demand growth driven by population increases, data-center load, and industrial electrification. Analysts including Doug Lewin have argued that appeals will become more frequent through 2027 unless dispatchable capacity additions accelerate.

Many Texans are feeling the heat this summer when they open the electricity bill. Family budgets are being tested by the high cost of cooling a home through record heat, leaving households wondering how to balance the budget with keeping the A/C running. Some relief is on the way. Governor Greg Abbott recently announced a historic amount of energy assistance funding for Texas households.

Governor Abbott announced on June 9, 2026 that Texas would receive $166 million in federal energy assistance funds. The Texas Department of Housing and Community Affairs (TDHCA) administers these federally funded energy assistance programs. Beginning January 1, 2027, eligible Texans can receive funds to pay utility bills, weatherize homes, and upgrade heating and cooling appliances.

This post is written for Ambit Brand customers, which is Texas households and small businesses shopping for retail electricity plans on the deregulated ERCOT market. It explains what the state is funding, who qualifies, how to apply, and what a Texas family can do until the TDHCA funds become available in January.

Funding Breakdown

Texas received $166 million in federal funding from two long-standing programs. TDHCA administers both at the local level. CEAP is the LIHEAP-funded utility bill assistance program, and the Weatherization Assistance Program (WAP) funds work that makes homes more energy efficient.

Per the Governor's June 9 announcement and the follow-up notice from TDHCA, funds may be used for: assistance with utility bills (past due or future electric, gas, or propane bills), weatherization work (insulation, air sealing, duct sealing), repair or replacement of health and safety related heating, cooling, and refrigeration equipment, and consumer counseling and case management for budgeting energy costs.

TDHCA does not take applications directly. Each of Texas' 254 counties has a local subrecipient agency (usually a city, county, or nonprofit community action agency) that distributes all funds. Related context: Texas utility shutoffs are rising, and knowing your relief options before a notice lands makes a real difference.

Who Is Eligible for CEAP and Weatherization Assistance

LIHEAP sets a national income ceiling of 150 percent of the Federal Poverty Level, and TDHCA uses that for CEAP. For 2026, a one person household is approximately $29,480; two people is $39,920; three is $50,360; and four is $60,800. For larger households, add about $10,440 for each additional person. TDHCA will release the 2027 income table before the funds become available in January.

To qualify, you do not need to already be behind on your bill. Households with a disconnection notice, a scheduled shutoff, or a documented medical need are prioritized, but any Texas family with income under the requirement may apply for help with a future bill. Both renters and homeowners qualify.

You still qualify if your income is below the limit, whether you own solar, are a customer on Texas Solar Buyback, or are on a fixed rate through 2027. The program looks at income, not what electricity plan you are on.

When and How to Apply

The best step for Texas families who believe they may qualify is to call 2-1-1 or 800-500-7074. The 2-1-1 line is a free statewide help line, and a case worker will match your ZIP code with the county CEAP provider for your location.

After finding your local agency, ask three questions. First, are you accepting CEAP or LIHEAP applications now, or should I call back after January 1, 2027? Second, what documentation do I need? That is usually a photo ID, proof of income from the last 30 days, a recent copy of your electricity bill, and Social Security cards for everyone in the house. Third, prior to the new funds opening, is there any interim assistance available right now?

Local agencies know what they have in stock. Some still have leftover funds from earlier LIHEAP cycles and can help immediately. Others will start waiting lists for the January 2027 funding. A full list of CEAP contract holders is available at tdhca.texas.gov.

Calling early will not be penalized, and there is no fee to apply. If anyone tries to charge you a fee to help you apply, it is a scam.

What Texas Households Can Do About Their Summer Bill Right Now

Waiting six months is a long time, especially when the hottest bills of the year land between July and September. Here are five practical moves any Texas household can make this week to lower the number on the next bill, no matter what your income is.

Read the Electricity Facts Label on your current plan. Every retail electricity plan in Texas comes with an EFL that lists out the energy charge, the base charge, and the TDU delivery charge by level of usage. A lot of families are on a plan that penalizes high summer usage and never notice. Plans designed for higher usage are the better choice for anyone using above 1,000 kWh per month. If you have never read one carefully, our line-by-line EFL walkthrough shows what to look for. Delivery charges specifically have moved this year, as we covered in why your Texas electric bill jumped in June 2026.

Check your contract expiration date. If your fixed-rate contract has expired and you have rolled to a month-to-month rate, your kWh price may have jumped significantly. Rolled-over month-to-month rates are often the most expensive product a retailer offers. Locking in a new fixed-rate plan like Ambit's Lone Star Classic, or moving to a straightforward variable option like Lone Star Flex, can rein that in. Our fixed vs variable guide walks through which fit which household.

Shift heavy usage into off-peak hours. The 3 to 7 p.m. window is where a lot of households run dishwashing, laundry, pool pumping, and EV charging. If your family already uses a lot of overnight or weekend electricity, a plan with free nights or free weekends may cut a meaningful percentage off your bill without changing anything about the house itself. See our free nights vs free weekends comparison to see which pattern matches your household.

Set the thermostat one to two degrees higher on days when the house is empty. The U.S. Department of Energy notes that raising the thermostat during hot weather delivers meaningful cooling savings, especially when the house is empty for eight hours a day.

Ask your current provider about a payment plan before you fall behind. Every retail electric provider in Texas has to offer a deferred payment plan under Public Utility Commission of Texas rules if you request one in good faith. Getting on a plan before a shutoff notice arrives is easier than fighting one after.

The Bigger Picture

$166 million is real help, but it is not a full solution for a Texas summer. Think of it as a safety net for the households that need it most while the rest of the state deals with rising delivery charges, a growing grid, and record peak demand. Plan choice is still the single biggest lever a Texas family controls, and the summer months are when a poorly matched plan hurts the most.

Households within the income limits should put a reminder on the calendar for January 1, 2027 and make the 2-1-1 call now to get on the local agency's list. Households above the income limits should use the summer to review the Electricity Facts Label, the contract expiration date, and the household's usage pattern. Both paths lead to the same place: a lower bill in August.

Rates and plan availability change. Plan details and Electricity Facts Labels are provided upon request as of July 14, 2026, and enrollment is subject to credit approval.

The summer heat is here, and with it, the start of high electricity usage and high electricity bills. Texas homeowners may notice a change between May and June billing cycles. There is a reason, and it shows up on the second to last line of the bill: the TDU delivery charge. This charge is not the result of changing plans or providers.

As of June 1, 2026, the Texas regulated delivery utilities (the wires companies, not your retail electricity provider) updated their residential delivery rates. The new schedules were published in the PUCT's TDU Rates summary and took effect at the start of the June billing cycle. The majority of homes in Oncor territory will see an increase. While the rate change itself is small in cents per kWh, summer is also when usage peaks, so the impact lands at the worst possible time of year.

This article walks through what changed, why your retail electricity provider cannot negotiate it away, how much it adds to a typical summer bill, and four practical steps Texas homeowners can still take to cushion the hit.

Changes Effective June 1, 2026

In Texas, every household in the deregulated ERCOT market sees two distinct line items on the same bill. One is the energy charge from a retail electricity provider (REP). The other is the delivery charge from the local TDU (the wires utility that owns the poles and meters in your area). Each TDU is regulated by the Public Utility Commission of Texas (PUCT), and the TDU charge is the same for every customer in that territory regardless of which REP they buy energy from.

Residential delivery rates published in the PUCT's TDU rate table, as of June 1, 2026:

The biggest mover here is Oncor. As of June 1, 2026, a jump from the March 2026 rate of about 5.6 cents per kWh up to 6.1196 cents per kWh is roughly a half cent increase on every kWh delivered to your home. That sounds small until you multiply it by a summer month usage profile. (For context on the broader Oncor rate trend earlier in the year, see our 2026 Oncor rate increase analysis.)

Note: Plan details and rates subject to change at PUCT review. Energy facts label available with every plan. The figures above are accurate as of June 1, 2026. Always check your most recent Electricity Facts Label (EFL) for the current charges that apply to your specific plan and address.

Why You Cannot Negotiate the Delivery Charge

This is the part many Texas homeowners only discover when the bill goes up. Your REP has no control over the TDU charge. When you shop for an electricity plan on a marketplace or sign up directly with Ambit, the price you compare is the energy charge plus any fees the REP itself sets. The TDU delivery charge is a regulated pass through. As of June 1, 2026, it is the same on a 7 cent plan and a 14 cent plan, and it does not move when you switch providers.

What this means in practice: if your bill jumped this month because Oncor's volumetric delivery rate went up, switching to any other Oncor area provider on the same plan structure will not undo the increase. The wires charge is the wires charge. The only place a REP can actually save you money is on the energy charge itself, on plan structure (fixed vs. variable, time of use, free nights), and on whether you stay on a competitive rate versus drifting onto a holdover or month to month rate after your contract ends.

How Much Will This Add to Your Summer Bill?

A typical Texas single family home uses somewhere between 1,400 and 2,200 kWh during a hot July or August billing cycle, depending on square footage, insulation, and how aggressively the AC runs. Using the new Oncor volumetric rate, as of June 1, 2026, of 6.1196 cents per kWh:

At the prior March 2026 rate of about 5.6 cents per kWh, the same 1,500 kWh month would have generated about $84 in volumetric charges. That is a real $8 to $10 increase on the delivery side alone, before the energy charge from your REP enters the picture. Over a four month Texas summer, that compounds to $30 or more in extra delivery costs.

That is why a $0.005 per kWh shift in a regulated rate is not a rounding error for Texas families. It is a quietly material number on the bill.

Four Things Texas Homeowners Can Actually Control

You cannot change the TDU rate. But you can change four things that determine how badly it hits your wallet this summer.

1. Confirm you are not drifting on a month to month rate

If your fixed rate contract expired and you did not renew, you may have been rolled onto a holdover or month to month rate that is often two to four cents higher per kWh than the fixed rates currently available as of June 1, 2026. Log into your account or pull out your most recent bill and check the line that says Electricity Facts Label or Plan Name. If it does not match the plan you originally signed up for, your REP rolled you. This is the single biggest, most overlooked summer bill saver.

2. Match your plan structure to your actual usage pattern

A free nights plan can be a strong fit if most of your usage is genuinely overnight (laundry, EV charging, dishwasher) and you keep daytime AC efficient. It is a poor fit if you work from home and keep the thermostat at 72 all day. Our Free Nights Electricity Plans in Texas pillar guide walks through who actually wins on those plans, and our analysis of whether free nights plans are worth it shows the math for typical Texas usage profiles.

3. Shift what usage you can to off peak hours

ERCOT's grid is most stressed (and wholesale prices spike) between roughly 3 PM and 8 PM in the summer. Even on a flat rate plan, that is when conservation requests get issued and the system is most fragile. Pre cooling the house before 3 PM, running the dishwasher and laundry after 9 PM, and avoiding oven use during peak hours all help. The 2026 summer outlook we covered in our Texas summer electricity bills guide goes deeper on the demand profile.

4. Tighten the easy efficiency wins before September

A clogged AC filter alone can add 10 to 15 percent to your cooling load. So can a thermostat set to 70 instead of 76. Closing blinds on west facing windows in the afternoon is free and meaningful. None of this is glamorous, and none of it offsets the delivery rate change one for one, but stacked together they routinely save 100 to 200 kWh per month on a typical Texas home.

Will Anything Get Better in Late 2026?

There are two storylines worth watching.

First, the PUCT continues to review distribution cost recovery factors (DCRF) and transmission cost recovery factors (TCRF) on a rolling basis, and not every adjustment is upward. AEP Texas North's June 1, 2026, rate actually decreased modestly. The TDU rate table is updated at PUCT, and rates can shift again in the fall and at year end.

Second, on June 18, 2026, the PUCT approved the first phase (Batch Zero) of ERCOT's large load interconnection framework. The headline impact is on grid reliability for data centers and other large industrial loads, but a more stable grid with better planned generation should put downward pressure on extreme summer events, which is the underlying driver of many recent rate adjustments.

Bottom Line for Texas Homeowners

The TDU delivery rate change that took effect June 1, 2026, is real. It is meaningful for households in Oncor territory in particular, and it is genuinely outside your REP's control. What Texas homeowners can control is whether they are on a current competitive rate plan, whether the plan structure matches their usage, and whether their home is running efficiently during peak hours.

If you would like a no pressure look at your current bill against the plans we offer in your TDU territory, we are happy to help. Request a quote with your ZIP code and your most recent bill, and we will walk through whether a rate or plan structure change would actually save you money under the new delivery schedule.

Frequently Asked Questions

Why did my Texas electric bill go up in June 2026 even though I did not change plans?

Most likely because your TDU's residential delivery rate changed on June 1, 2026. As of June 1, 2026, in Oncor territory, the volumetric delivery charge rose from the March 2026 rate of about 5.6 cents per kWh up to 6.1196 cents per kWh. That added charge appears on every kWh delivered to your home, regardless of which retail electricity provider you use.

Can I avoid the new TDU delivery charge by switching providers?

No. The TDU delivery charge is regulated by the PUCT and is identical for every customer in that TDU territory. Switching from one Oncor area REP to another does not change the delivery line on your bill. What can change is the energy charge from your REP and the structure of your plan.

Which Texas TDU had the biggest 2026 delivery rate increase?

Oncor's residential volumetric delivery rate is the biggest mover among the major TDUs. As of June 1, 2026, the volumetric charge rose from the March 2026 rate of about 5.6 cents per kWh to 6.1196 cents per kWh. CenterPoint, AEP Texas Central, and TNMP are roughly flat or modestly changed; AEP Texas North's rate moved slightly down.

Where can I see the official Texas TDU delivery rates?

The PUCT publishes the current residential delivery rates for all five Texas TDUs at puc.texas.gov in the TDU Rates summary. Your most recent Electricity Facts Label (EFL) also shows the delivery charges that apply to your specific plan and service address.
