This capture directly answers [[question-verify-ercot-large-load-queue-phantom-load-figures]], which flagged [[claim-ercot-large-load-queue-quadrupled-2025-phantom-load]] as `[unverified-quant — needs primary]` because its numbers rested only on Latitude Media (Tier 2) reporting of ERCOT's own data. Three ERCOT primary documents were located and fetched directly with `extract_pdf` (all TLS-verified, not the "unverified" transport that would trigger elevated safety suspicion) and one relevant secondary article was independently re-archived with `archive_page`. **Bottom line: the 226 GW and 63 GW figures are confirmed directly against ERCOT's own board materials. The 77% data-center share is NOT confirmed at that value — ERCOT's own primary source says ~73%, a materially different number than the widely-reproduced trade-press figure.**

## Claim: ERCOT's own Board of Directors presentation confirms the ~226 GW large-load queue (Nov 18, 2025) and the ~63 GW December 2024 baseline

ERCOT Vice President of System Planning and Weatherization Kristi Hobbs presented "Item 16.2: System Planning and Weatherization Update" to the ERCOT Board of Directors on December 8–9, 2025 (slide deck revised 12/02/25). A slide titled "Large Load Interconnection Requests (as of November 18, 2025)" states the key takeaway directly in ERCOT's own words. The same deck separately reports that ERCOT received 225 new Large Load interconnection requests in 2025, representing a 270% increase in requested MW demand since January 2025 — an independent, ERCOT-stated growth figure consistent with (though not identical in derivation to) the "nearly quadrupled" framing used by [[claim-ercot-large-load-queue-quadrupled-2025-phantom-load]].

## Claim: ERCOT's primary source states ~73% of the queue is data centers — not the ~77% figure widely reproduced in trade press

The trade-press figure this capture was sent to verify — "about 77% of that load" is data centers, per Latitude Media (Catherine Boudreau, Dec 3, 2025) — does **not** match ERCOT's own board presentation, which states "~73% are data centers" for the same November 18, 2025 snapshot. This is not a rounding difference; 73% and 77% are distinct reported figures. A separate trade outlet (Blockspace Media) independently reports "72.9%," which is consistent with ERCOT's ~73% and inconsistent with the 77% figure — suggesting 73% (not 77%) is the number that actually traces to ERCOT.

One plausible (not confirmed) explanation for the mix-up: the *same* ERCOT slide deck separately reports that of the 1,999 active *generation* interconnection requests (the supply-side queue — see [[claim-us-interconnection-queue-exceeds-installed-capacity]] for the analogous national figure), 77% are solar and energy storage resources — a completely different metric (generation-queue fuel mix, not large-load data-center share) that happens to share the number "77%." Whether Latitude Media's 77% figure originated from a different, more recent ERCOT source not accessed in this capture, or from a conflation of these two distinct 77%/73% statistics, could not be determined from the sources gathered here.

## Claim: ERCOT's own data shows only a small fraction of the 226 GW queue has actually been built — quantifying the "phantom load" gap more precisely than the existing note's inference

ERCOT's own "Questions and Answers About the Large Load Interconnection Process" document (Rev. 12.15.25) explains the five status categories ERCOT uses to track queue projects and gives ERCOT's own figure for how much of the queue is real, delivered load rather than a filed request: as of the same November 18, 2025 snapshot used for the 226 GW headline figure, only 5,302 MW (~2%) of total queued load had been "Observed Energized," and the "Approved to Energize But Not Operational" category was under 1%. ERCOT states the largest category, "No Studies Submitted," "includes the majority of large loads that are currently in the interconnection process" — i.e., most of the 226 GW has not yet even completed the first formal study step. This is a more precise, ERCOT-sourced quantification of the requested-vs-delivered gap than the existing claim-note's inference from system-wide generation additions (~23 GW added 2024–25, a different metric measuring new generation capacity rather than queue-specific energization). Note: ERCOT's own documents reviewed here do not use the word "phantom" — that framing is trade-press/analyst vocabulary describing the gap; the underlying magnitude of the gap, however, is confirmed in ERCOT's own categorization.

- source_quote: "As of November 18, 2025, ERCOT had identified 5,302 MW of large loads in this category, which constitutes approximately 2% of the total load in ERCOT's large load interconnection process." — and: "No Studies Submitted: This group includes all large load projects for which no Large Load Interconnection Study (LLIS) has been submitted to ERCOT... This category includes the majority of large loads that are currently in the interconnection process."

## Claim: the 226 GW figure is a specific dated snapshot, not a fixed constant — ERCOT's own December 2025 planning report already shows growth to ~238.6–239 GW weeks later

A separate ERCOT primary document, "Report on Existing and Potential Electric System Constraints and Needs" (December 2025), gives a newer snapshot: as of December 17, 2025 — about four weeks after the November 18 snapshot behind the 226 GW figure — ERCOT was tracking nearly 238.6 GW of large-load interconnection requests, with the report's key-takeaways page independently stating the total load seeking interconnection at "approximately 239 GW." This confirms the general order of magnitude and the rapid-growth trend, but underscores that "226 GW" specifically pins to the November 18, 2025 ERCOT snapshot cited in [[claim-ercot-large-load-queue-quadrupled-2025-phantom-load]] — any later citation of "the ERCOT large-load queue" without a date is citing a moving number.

- source_tier: 1 (ERCOT's own primary report, PDF fetched via extract_pdf with verified TLS)
- source_quote: "ERCOT continues to track nearly 238.6 GW of large load interconnection requests." — and, on a separate line of the same document: "interconnection is approximately 239 GW." (Note: this document's PDF text extracts in an interleaved two-column order; only phrases that appear as single contiguous lines in the raw extracted text are quoted here — the "more than three times as many...compared to 2024" framing surrounding the 239 GW figure is present in the document but spans interleaved column lines in the raw text, so it is paraphrased above rather than quoted, per the fabrication rule's requirement that a source_quote be verbatim-grounded.)

## Further leads

- ERCOT has contracted McKinsey & Company (announced Dec 2025) to help redesign the Large Load Interconnection process; a joint framework with short- and mid-term fixes is expected in early 2026 — per the Dec 2025 "Report on Existing and Potential Electric System Constraints and Needs" (Tier 1, same source as Claim 4 above).
- ERCOT's separate *generation* interconnection queue (supply side, distinct from the large-load/demand queue analyzed here) stood at 432 GW across 1,999 active requests as of Oct 31, 2025, with solar (158 GW) + storage (176 GW) = 77% of that total — per the same Item 16.2 board deck (Claim 1/2 source). This is the ERCOT-specific counterpart to the national LBNL figure in [[claim-us-interconnection-queue-exceeds-installed-capacity]].
- Texas Senate Bill 6 (2025) directs the PUC to establish new large-load interconnection standards and requires a "Net Metering Review" for large loads netting with existing generation — a regulatory-response thread not explored in depth this capture; source: ERCOT Large Load Interconnection Process Q&A (Claim 3 source).
- News coverage of the same Dec 9, 2025 ERCOT board meeting (Utility Dive, Blockspace Media, S&P Global — all Tier 3) quotes VP Kristi Hobbs saying ERCOT "has outgrown the process" built for large loads and that many requests "may be speculative" — the word "speculative" does not appear in the three ERCOT primary PDFs pulled for this capture; a follow-up should check whether Hobbs used that word live at the board meeting (video at ercot.new.swagit.com) before treating it as an ERCOT-primary claim.
- ERCOT's own Q&A document states only 7,502 MW have been "Approved to Energize" cumulatively since January 2022 — a multi-year complement to the point-in-time "~2% Observed Energized" figure in Claim 3.
- ERCOT's Q&A explains "must-study" vs. "may-study" load classification and the conditions that trigger re-studies (a common cause of queue delay) — mechanism detail worth its own future capture on why the queue process itself is slow, distinct from the "how much is real vs. speculative" question this capture addressed.

## Entity candidates

- 2022 Interim Large Load Interconnection Process (established via ERCOT Market Notice W-A032522-01, March 2022) — concept/process — the original baseline process, built to handle roughly 40–50 large loads at a time, that the current ~226–239 GW queue overwhelmed and that the formal PGRR115/NPRR1234 process (effective Dec 15, 2025) replaced. Flagged first per the vault's known blind spot: without this earlier process as the comparison point, "ERCOT has outgrown the process" reads as an undated generality rather than a specific, datable before/after.
- Kristi Hobbs — person — ERCOT Vice President of System Planning and Weatherization; the named official whose December 2025 board presentation is the Tier-1 source for the 226 GW / 63 GW / ~73% figures verified in this capture.
- PGRR115 / NPRR1234 (formal Large Load Interconnection Process, approved May 2025, effective December 15, 2025) — concept — the current rule that replaced the 2022 interim process; defines the "No Studies Submitted / Under ERCOT Review / Planning Studies Approved / Approved to Energize / Observed Energized" categories this capture's Claim 3 draws on.
- Public Utility Commission of Texas (PUCT) — concept/organization — approves ERCOT's interconnection rules (PGRR115, PGRR117, etc.) and is separately running large-load interconnection rulemaking under Texas Senate Bill 6.
- McKinsey & Company — organization — contracted by ERCOT (Dec 2025) to help redesign the Large Load Interconnection process; deliverable expected early 2026.
- Texas Senate Bill 6 (2025) — concept — legislative driver behind new PUC/ERCOT large-load interconnection standards and the Net Metering Review requirement.

> [!note] Seek's commentary:
> The most interesting finding here isn't confirmation, it's correction: the headline "226 GW / 63 GW" pair holds up almost exactly against ERCOT's own board materials, but the "~77%" data-center share — the number that gets repeated everywhere, including in this vault's own existing claim-note — does not match ERCOT's own presentation, which says ~73%. That the two numbers that happen to coexist in the same ERCOT slide deck (73% of large loads are data centers; 77% of generation requests are solar+storage) are close enough to get swapped in secondary reporting is a small, concrete illustration of exactly the kind of number-laundering the sourcing floor exists to catch. It's not a huge error — "large majority is data centers" survives either way — but it is a real, checkable discrepancy that only going to the primary surfaced.
