ERCOT Says Texas Demand Could Near an All-Time Record This Week — Does a Record Change What You Pay?
Update — July 22, 2026: The record did fall — unofficially. ERCOT logged a preliminary peak of about 87,403 MW this week, above the 85,508 MW all-time record set on August 10, 2023. (Houston Public Media reported the new high on Tuesday, July 21; FOX Local cited the 87,403 MW figure on July 22.) ERCOT stresses that intraday readings are preliminary and do not become official until market settlement is finalized months later. Just as important for what you pay: the grid absorbed the record comfortably — no conservation appeal or emergency, operating reserves above 10 GW, and forecast capacity exceeding demand by more than 30 GW most days, with solar supplying roughly 35–45% of generation Monday and Tuesday. That reinforces the point below: a demand record is a wholesale, megawatt-level event, and for a fixed-rate household it did not change your price.
Quick Summary: ERCOT said on Monday, July 20, 2026 that it expects “moderately high to high demand with peaks in the mid-80,000- to lower-90,000-megawatt range” this week, as temperatures above 100°F meet a Gulf system that has now become Tropical Storm Bertha. ERCOT’s all-time demand record is 85,508 MW, set on August 10, 2023 — so the top of that forecast range would break it. ERCOT’s six-day supply-and-demand forecast showed enough capacity expected to meet demand. Here is the part that gets lost in the coverage: a demand record is a megawatt event in the wholesale market. Your bill is your kilowatt-hours times the price in your contract. If you hold a fixed rate, a record afternoon does not change your price at all. The heat that causes it changes your usage — and that is where a plan built around the 1,000 kWh advertised rate quietly stops being cheap.
What ERCOT Actually Said
In a post on X on Monday, the Electric Reliability Council of Texas said it is “expecting moderately high to high demand with peaks in the mid-80,000- to lower-90,000-megawatt range,” as reported Monday afternoon by FOX Local’s Texas stations. Two things are arriving in the same week: forecast temperatures above 100°F across much of the state, with feels-like readings near 110°F, and a tropical system in the Gulf heading toward the northern Gulf Coast.
The number worth anchoring on is the record itself. ERCOT’s own yearly peak-demand records page — last updated April 28, 2026 — lists the all-time record as 85,508 MW, set on August 10, 2023. ERCOT notes on that same page that “all records are unofficial until final settlements occur,” and that it uses the integrated system load for a full hour rather than instantaneous peaks. So the lower end of this week’s forecast range sits just under the record and the upper end sits above it. A record is possible. It is not a certainty, and forecast load is not measured load.
For scale, using ERCOT’s own conversion: the grid operator says 1 MW serves roughly 250 residential customers during ERCOT peak hours. If demand reached the low 90,000s, it would sit several thousand megawatts above the 2023 record — on that arithmetic, well over a million homes’ worth of additional peak-hour demand compared with the highest hour Texas has ever recorded.
A historical footnote from the same ERCOT table: the previous record before 2023 was 80,148 MW, and it was set on July 20, 2022 — four years ago to the day. Late July is simply when this happens.
Keep this week’s figure separate from the seasonal one you may have seen. ERCOT’s summer 2026 outlook put the projected peak for the season at roughly 92,211 MW — a forecast for what the summer could reach, which we covered in June. That is a seasonal projection, not a reading from any particular day. Posts that present a 92 GW-class figure as something that already happened are conflating the two.
As of Monday evening we had seen no report of an ERCOT Weather Watch or conservation appeal for this week; ERCOT’s six-day forecast showed sufficient capacity. Grid conditions change quickly — ERCOT’s Texas Advisory and Notification System page carries the current status.
A Demand Record Is a Megawatt Story, Not a Rate Story
Every summer this gets muddled, so it is worth stating plainly. A peak-demand record describes the whole ERCOT system at one hour: how many megawatts all of Texas pulled at once. Your electricity bill describes one meter over a month: how many kilowatt-hours you personally used, multiplied by the price your contract says you pay.
Those are different markets, and for most Texas households a contract sits between them:
| If you are on… | Does a record-demand afternoon change your price? |
|---|---|
| A fixed-rate contract | No. Your energy price is locked for the term. That is precisely what you bought: a hedge against exactly this kind of week. Narrow pass-throughs for regulated grid and delivery costs still exist and are spelled out in your contract. |
| A variable-rate plan | It can. A variable rate has no contractual ceiling and the provider may change it month to month. A hot, tight market is the classic reason it moves against you. |
| An indexed or wholesale-linked plan | Directly. These track a wholesale formula, so scarcity pricing in the hours around a peak flows through to you. This is the smallest group of Texas customers and the most exposed. |
If you are not certain which of the three you hold, it is on your Electricity Facts Label, and our plan types guide explains how to tell them apart. This week is a good week to know the answer.
What Actually Moves Your July Bill: Volume, Not the Record
Here is the thing that does cost fixed-rate households real money in a week like this, and it has nothing to do with the record. Extreme heat pushes a Texas home’s monthly usage far above 1,000 kWh — and 1,000 kWh is the single point at which almost every advertised Texas rate is calculated. Plans are designed to look their best at that number. Your July is not that number.
An illustration, using the linear interpolation across the three Electricity Facts Label price points that our methodology applies to every plan. Two hypothetical plans, both fixed:
| Plan A — bill-credit shape | Plan B — flat standard fixed | |
|---|---|---|
| EFL price at 1,000 kWh | 13.9¢/kWh | 14.8¢/kWh |
| EFL price at 2,000 kWh | 15.6¢/kWh | 14.4¢/kWh |
| Bill at a mild 1,000 kWh month | $139.00 | $148.00 |
| Bill at a 1,900 kWh July | $293.17 | $274.36 |
Same two plans, opposite answers. Plan A is the cheaper plan by $9 at the advertised 1,000 kWh point — and the more expensive plan by $18.81 in a hot 1,900 kWh month. Nothing about either plan changed. The household’s usage moved, and the ranking flipped. Across the Texas market our own analysis puts the cost of that mistake at roughly $43 a month, about $518 a year, for a large home that picks the plan advertised cheapest at 1,000 kWh instead of the one actually cheapest at its real usage — comparing standard fixed-rate plans only.
That is the number worth reacting to this week. Not the megawatt record — which costs a fixed-rate customer nothing — but the fact that a record-heat month is exactly the month your plan is furthest from the usage level its marketing was tuned for.

The Storm Arriving in the Same Week
The system we wrote about on Sunday as Tropical Depression Two has since become Tropical Storm Bertha. The track has also shifted east of where Sunday’s guidance pointed: current forecasts have Bertha reaching Louisiana around Wednesday, with the Upper Texas Coast in play later in the week as a weaker system. Houston-area utilities are preparing regardless — CenterPoint Energy has activated its emergency operations center.
Forecasts move; treat this as one. The Texas end of this track changed materially in about 36 hours, which is normal for a system this early in its life. The National Hurricane Center and your local National Weather Service office carry the current forecast. Nothing in the billing mechanics below depends on where it lands.
The two stories interact in one way worth understanding. Heat drives demand up; a landfalling storm knocks distribution lines out, which removes demand and, on the customer side, can drop a household’s monthly usage below a bill credit’s threshold. We worked that arithmetic through in Sunday’s piece, and it is the mirror image of the example above: the same plan design that punishes you for using much more than 1,000 kWh also punishes you for using slightly less. It is only cheap in a narrow band.
What’s Worth Doing This Week
- 1. Find out which of the three plan types you hold. Fixed, variable or indexed. It is the single fact that determines whether any of this week’s market news can reach your price. It is on your EFL — our EFL reading guide shows where.
- 2. Check your contract end date. This is the genuinely urgent one. A contract that lapses in July or August usually rolls to a month-to-month holdover rate at the worst possible time of year. See what to do when your contract ends.
- 3. Price your plan at your real July usage, not 1,000 kWh. Pull last July’s kWh off an old bill and use that. Our bill estimator will run any usage level you give it.
- 4. Do not expect a switch to help this month. Switches are processed through ERCOT’s retail market systems and take effect at a future meter read. Shopping now is about August onward, not about this week’s bill.
- 5. Know your disconnection protections. Texas has rules covering when a residential customer can and cannot be disconnected during extreme heat, plus deferred payment plans. We covered them in our guide to Texas disconnection rights.
And if conservation notices do go out later in the week, they are worth honouring on their own merits — but be clear-eyed about why. Voluntary conservation protects the grid during the tightest hours. It is not a billing strategy, and shifting a few hundred watt-hours out of a 5–9 p.m. window will not meaningfully change a fixed-rate customer’s monthly statement. Choosing the right plan for your usage level will.
