The all-time ERCOT demand record stood for nearly three years. This week it lasted about 24 hours. On Tuesday, July 21, the grid hit 87,403 MW, finally breaking the 85,508 MW mark set in August 2023. On Wednesday, load blew straight past 91 gigawatts to 91,308 MW. Triple-digit heat from Dallas to Houston, humidity riding in off Tropical Storm Bertha, heat indices touching 112°F — and not one conservation appeal, not one emergency notice, not one incident.
That is the week in one sentence: the biggest load ERCOT has ever served, absorbed with a shrug. Meanwhile, the paperwork window closed on the 438 GW of future load waiting to get in, and a former Bitcoin miner on the Gulf Coast fully leased out a 1 GW AI campus for $19.6 billion. Demand present, demand future, and the machine that decides who gets to plug in — all in seven days.
"Last Night It Was Nearly 12,000"
The demand record was actually the least interesting record of the week. Wednesday also set new all-time marks for maximum net load (75,733 MW), maximum solar output (34,665 MW), and — the one that matters most — maximum battery storage discharge at 11,980 MW. Grid analyst Doug Lewin put the trajectory plainly: "Two years ago when the grid reached a new 5-minute peak demand record, we had nearly 4,000 megawatts of batteries deployed. Last night it was nearly 12,000, a 3x increase in 2 years". Batteries topped 10 GW of discharge five separate times in July.
Readers with long memories will recall this newsletter flagging the previous storage discharge record of 11,674 MW. That number is now a footnote. So is the old demand record, and possibly the new one — ERCOT's own outlook has summer peak potentially topping 92 GW, and its odds of a grid emergency jump from 0.21% in July to 5.96% in August.
The structural story is that Texas built roughly 53.6 GW of solar and around 29 GWh of storage, and the two now function as a single machine: solar carries the afternoon, batteries carry the evening ramp, and the heat wave that was supposed to challenge the grid instead produced the quietest record-breaking week in ERCOT history. Two summers ago, 91 GW was a number you modeled in an emergency scenario. This week it was a Wednesday.
Worth sitting with what didn't happen, too. No scarcity pricing event worth the name. No EEA levels. No press conference. The August 2023 record came with conservation appeals and a grid operator visibly sweating; this one came with a market notice and a records table. Every legislative session since Uri has been fought over the premise that the ERCOT fleet can't be trusted in extreme heat. The fleet just served six gigawatts more than it ever has, on the hottest week of the year, without anyone outside the industry noticing. That premise is due for an update.
Hut 8 Fills Beacon Point: 1 GW, $19.6 Billion, One Tenant Unnamed
On Monday, Hut 8 — a company that mined Bitcoin for a living not long ago — announced a second 15-year lease at its Beacon Point campus in Nueces County: 352 MW of IT capacity worth $9.8 billion in base rent, signed with the same unnamed investment-grade hyperscaler that took Phase 1 in May. That tenant now holds 704 MW at the campus, the full 1 GW is commercialized, and the campus-level contract value stands at $19.6 billion — or up to $50.2 billion if all three five-year renewal options get exercised.
Run the arithmetic on the base term and it comes out to roughly $1.3 billion a year across the campus, or something like $1.9 million per megawatt of IT capacity per year, contracted for fifteen years to a counterparty with an investment-grade rating. That is not a hosting deal. That is a utility's revenue profile wearing a data center's badge, and it explains why a company that was mining Bitcoin eighteen months ago now trades like an infrastructure REIT. The market has stopped asking whether miners can convert; it has started pricing which ones did it first.
The press release says "fully commercializes." The subtext says the miner-to-AI pivot is no longer a pivot; it's the business. And it's clustering: two weeks ago MARA agreed to buy a 1,200-acre, up-to-2-GW site from HIF USA one county up the coast in Matagorda, for up to $600 million. Nueces, then Matagorda. A Gulf Coast corridor of former miners selling power-dense real estate to hyperscalers is taking shape, and the common ingredient is not the buildings — it's the interconnection agreements signed back when these were crypto plays and nobody else wanted the power.
Batch Zero Closes Its Window. Now the Studying Starts.
Today, July 24, is the deadline for transmission and distribution utilities to submit their finalized Batch Zero eligibility packages to ERCOT. Load-side submissions closed July 10; deficiency cures run through August 31. After that, the first-ever batch study of the large-load queue — 438,000+ MW, roughly 89% of it data centers — begins in earnest. For scale: the queue is about 4.8 times the all-time peak the grid just served on Wednesday.
What comes out of the study matters more than what went in. Batch Zero sorts every applicant into load classes — the megawatts ERCOT will actually plan for versus the ones that exist mostly as optionality on a developer's term sheet. Everyone in the market privately expects the 438 to shrink dramatically once real deposits and real study costs attach to real projects; the open question is whether it lands near the ~100 GW that planners have been penciling in, or somewhere that forces a rewrite of every transmission plan in the state. The answer starts arriving after August 31.
Two related threads from the regulatory beat. First, the PUCT held a workshop Monday on implementing SB6's mandatory curtailment provisions for large non-critical loads — the fine print that determines whether a 500 MW campus is a grid asset or a grid liability at 5 p.m. in August. Second, the joint PUC/ERCOT ratepayer-protection memo that Governor Abbott ordered by July 17 — the one I noted last issue had not arrived on deadline — still has not surfaced publicly. The next tripwire in the directive is July 31, when the Commission is supposed to initiate action to cut residential transmission costs. One deadline missed, one week to the next.
Meta Buys the Evening Sun, Two Years Forward
Small story, telling shape: on Wednesday GameChange Energy announced it will supply trackers for Sabanci Renewables' Pepper and Lucky 7 solar projects in Texas — roughly 286 MWdc combined, with output contracted long-term to Meta to support its Texas data center load. Commercial operation is slated for the second half of 2027.
Look at what Meta is actually buying: the same resource class that just posted a 34.7 GW output record and carried the grid through its biggest week ever. Hyperscalers watched Wednesday happen too. The difference is they're contracting for it two years forward, project by project, before the batch study tells everyone else what their interconnection is worth.
What to Watch Next Week
July 31. The PUC's deadline under Abbott's directive to initiate action on residential transmission costs — and whether the overdue joint memo ever appears.
Batch Zero cure window. Deficiency fixes run through August 31; watch for any ERCOT signal on how many megawatts actually made it into the study.
TANEO's $350 million. Texas's advanced nuclear fund was slated to pick award recipients in July. Nothing public yet, and July is running out of days.
August heat. ERCOT's own emergency odds go from 0.21% to 5.96% next month. The record set Wednesday may not survive it.
Hut 8's tenant. Q2 earnings season may finally put a name on 704 MW of Beacon Point — and tell us whether the deal-a-week pace of miner-AI conversions holds.
