The Batch Zero clock.

On 2026-06-02 the ERCOT Board approved PGRR145/NPRR1325, the revision package that ends the serial large-load study process and replaces it with batches.1 The PUCT gave final approval on 2026-06-18 (the PGRR145 and NPRR1325 issue pages read “Approved on 06/18/2026”), so the package is locked. The table below separates completed rule actions from ERCOT targets and preserves routing by eligibility path.

Current status

ERCOT targets conditional-classification notices by August 31, 2026.

The PUCT granted ERCOT's three requested good-cause exceptions on 2026-08-20. ERCOT now intends to notify each interconnecting DSP or TSP of its Large Load's conditional classification by 2026-08-31. That conditional notice starts the Planning Guide §9.3.1(2)(a)(i)-(iii) dispute and reconciliation process. August 31, 2026 is ERCOT's announced target, not a PUCT-ordered deadline, final classification date, or customer filing deadline.3

Separately, approvals to energize are paused. ERCOT told the Commission it “will also refrain from granting further approvals to energize any Large Load data centers or virtual currency mining facilities until the verification has been completed,” and its 2026-08-20 update scopes that pause to facilities of 75 MW or greater. ERCOT may still approve energization for non-data-center large loads, and the pause does not reach medium loads. ERCOT sized the affected set at 17 Large Loads, 6,608 MW of total peak demand over five years, that have finished every other ERCOT process without approval to energize.5 The pause is ERCOT's own action under the Governor's 2026-08-03 directive. The PUCT order granting the good-cause exceptions does not itself order it.

Status reviewed August 27, 2026. Revalidate after August 31, 2026 or upon any new ERCOT or PUCT filing, whichever occurs first. Conditional classification notice does not establish that a project is in Batch Zero.

Every milestone, on a live clock

Date	Clock	Milestone	Status	Source
Jun 18, 2026	T+94	PUCT gave final approval to ERCOT's Batch Zero protocol package (PGRR145/NPRR1325) on 2026-06-18. The issue pages read "Approved on 06/18/2026." This establishes the adopted revision package; each later milestone's status below controls whether its date remains operative.	complete	ercot.com
Jul 10, 2026	T+72	ILLE submission deadline, two tracks: forms, attestations, and eligibility materials due to the interconnecting TSP/DSP; the §9.2.2(3) dynamic-model submission due to ERCOT directly (BatchZero@ercot.com by 2359 CDT, per market notice M-B062326-04). Missed means excluded from Batch Zero. Also the hard close of the legacy LLIS process. No further legacy study or restudy approvals.	scheduled	ercot.com

Jul 24, 2026	T+58	Two distinct July 24 flows, per the live LLI page routing table and market notice M-B062326-04. (1) Interconnecting TSPs/DSPs submit completed Large Load Interconnection details to ERCOT (BatchZero@ercot.com): the Batch Zero LIF workbook, the Interconnecting TSP Dynamic Stability Study Form (where applicable), the Section 9.2.1.4(3)(d) attestation (where applicable), and the forwarded ILLE forms, including notarized Form W Part A (PCLR) and Form X (WLPUN) where elected, which ILLEs filed with their DSP/TSP by July 10. (2) Separately, an ILLE on the Section 9.2.1.2 eligibility path submits its Section 9.2.1.2(1) attestation to its interconnecting DSP/TSP, not to ERCOT, by this same date; that attestation belongs to one eligibility path, not to every ILLE.	scheduled	ercot.com
Aug 1, 2026	T+50	QSA prerequisite gate for early-2027 energization: an ILLE seeking Initial Energization in January, February, or March 2027 must satisfy all Planning Guide §5.3.5 prerequisites by this date. The governing schedule then expected classifications on Aug 7. After this QSA gate passed, M-A080326-01 announced ERCOT would not issue classifications by the adopted Aug 7 deadline and would seek a good-cause exception.	scheduled	ercot.com
Aug 7, 2026	Closed	ERCOT notifies TSPs/DSPs of Batch Zero classification results, including eligibility determinations and identified dynamic-model or data deficiencies. 2026-08-07 is the adopted Planning Guide §9.3.1(2)(a) deadline (ERCOT market notice M-B062326-04, 2026-07-08). ERCOT did not meet it. On 2026-08-20 the PUCT granted ERCOT a good-cause exception from the deadline and allowed ERCOT to continue reviewing dynamic-data submissions after August 7, with the same 24-day cure period running from notice of a deficiency. The August 7 classification date is retained here as history, not as an operative deadline.	superseded	interchange.puc.texas.gov
Aug 31, 2026	T+20	ERCOT intends to notify interconnecting DSPs/TSPs of each Large Load's conditional classification by this date. The conditional notice starts the dispute and reconciliation process in Planning Guide §9.3.1(2)(a)(i)-(iii). This is ERCOT's announced target in market notice M-A080326-02, not a new adopted rule deadline.	ERCOT announced	ercot.com
Aug 31, 2026	Closed	The June 5 timeline deck projected a final inclusion cut on this date. Later primary-source actions changed the Batch Zero process. The August 20 PUCT order granted ERCOT's good-cause exceptions, and M-A080326-02 now uses August 31 for conditional-classification notices. Do not treat the older final-inclusion-cut marker as an operative deadline.	superseded	ercot.com
Nov 1, 2026	T−42	QSA prerequisite gate for Q2-2027 energization: an ILLE seeking Initial Energization in April, May, or June 2027 must satisfy all Planning Guide §5.3.5 prerequisites by this date. The 2026-08-20 PUCT order lets ERCOT include Large Loads it conditionally classifies as base load in this assessment before final classification. In its 2026-08-20 filing ERCOT put 17 Large Loads, approximately 6,874 MW, as potentially eligible. Inclusion in a QSA does not by itself authorize energization, and approvals to energize remain paused for Large Load data centers and virtual currency mining facilities.	scheduled	interchange.puc.texas.gov
Dec 10, 2026	T−81	ERCOT states it will file the Batch Zero Eligibility Verification Report and the Community Impact Review Report on this date. ERCOT's pause on further approvals to energize Large Load data centers and virtual currency mining facilities runs “until the verification has been completed”, so this filing is the first stated point at which that pause could lift. This is ERCOT's announced plan in its 2026-08-20 filing in PUCT Project 59142, not an adopted rule deadline or a PUCT order.	ERCOT announced	interchange.puc.texas.gov
Dec 17, 2026	T−88	The Commission open meeting ERCOT identifies for its Batch Zero Eligibility Verification Report and Community Impact Review Report. This is ERCOT's announced plan in its 2026-08-20 filing in PUCT Project 59142. No PUCT order sets this date, and no outcome for any project follows from the meeting being scheduled.	ERCOT announced	interchange.puc.texas.gov

How the batch study works, in plain English

Until now, every large load (≥75 MW) was studied one at a time, in the order it showed up, a serial queue that produced a 466,497-MW request ledger as of the 2026-06-18 LLWG report. Batch Zero studies everyone who qualifies at once.4

Get in: By 2026-07-10, an interconnecting large-load entity must submit its study and dynamic-model data plus eligibility materials. That date is also the last day for legacy approvals under the serial process. By 2026-07-24, the transmission or distribution provider files the qualification package (attestations, disclosures, financial-security confirmations) and projects electing the PCLR pathway file Form W Part A (notarized and binding). ERCOT was to return classification results by 2026-08-07, the adopted Planning Guide §9.3.1(2)(a) deadline. ERCOT missed that date. On 2026-08-20 the PUCT granted ERCOT's good-cause exceptions, including authority to delay classification and continue dynamic-data review after August 7. On 2026-08-21 ERCOT said it intends to notify the interconnecting DSP or TSP of each conditional classification by 2026-08-31. Receipt of that notice starts the §9.3.1(2)(a)(i)-(iii) dispute and reconciliation process. A post-August-7 dynamic-data deficiency gets a 24-day cure period measured from actual notification, not from August 31, 2026.3
Get studied: ERCOT studies the batch as a group and publishes a final report with MW allocations. ERCOT has not published a final-report date, so this clock does not invent one. Allocated MW is reserved against restudy; a commitment gate (signed interconnection agreement plus financial commitments) converts an allocation to firm, and non-committed projects are automatically removed. The minimum allocation threshold is roughly 100 MW (90% for requests of 100 MW or less).1
Curtailable power: The PCLR election (Provisional Controllable Load Resource) trades firmness for speed: firm service up to a load-commitment limit, with consumption above it curtailable via SCED dispatch, ahead of transmission buildout. It is not an eligibility bypass, and the obligations run with the facility.1
Miss it, wait: Projects excluded from Batch Zero wait for Batch 1, a potential case build in June 2027.1

Proposed §25.194 capital terms

Proposed, not adopted

PUCT Project 58481 has no adoption order. Staff Item 206 (filed 2026-08-24) is a draft recommended revision of the proposed rule, not an adopted rule and not customer copy.2

Interconnection fee: Item 206 struck the former $50,000/MW non-refundable interconnection fee in full (old (f)(7)). That figure is not a current proposed interconnection fee.
Proposed security: SLLIA security is the greater of $50,000/MW of contracted peak demand or allocated upgrade costs ((f)(2)(B)(i)).
Proposed study fee: A flat $100,000 ((d)(2)(A)(i)). The former $300,000 / 250 MW+ tier is struck.

A proposed 300 MW example: $100,000 study fee plus security of the greater of about $15 million ($50,000 × 300 MW) or allocated upgrade costs. There is no additional interconnection fee in Item 206. Source: Staff Item 206, docket 58481. Reviewed August 27, 2026.

The public deadlines show the process. They cannot show whether one named project has the required evidence or who owns each gap. This frozen research example shows the source evidence, contradictions, unknowns, and public facts that would change the estimate. Radar changes can trigger new simulations or shadow decisions; they do not authorize production action or establish customer readiness.
