Key takeaways
- ERCOT issued conditional Batch Zero classifications on September 3, 2026 for large-load interconnection requests of at least 75 MW.
- A project reclassified from Base Load to Studied Load has a tight three-business-day dispute window measured from notification.
- Transmission and distribution providers must notify affected customers of a reclassification within two business days.
- An excluded project can seek relief through ERCOT’s Alternative Dispute Resolution process, but the sources reviewed here do not publish a comparable filing deadline or a step-by-step filing procedure.
- A separate 14-business-day evidence period applies only to a narrower good-cause-exception pathway; it is not a general extension of the three-day dispute window.
What ERCOT decided on September 3
ERCOT’s September 3 screening sorted submitted large-load requests into three broad outcomes: Base Load, Studied/Allocated Load, or exclusion from Batch Zero. The classifications were conditional and private. ERCOT did not publish project names, locations, requested capacity or individual decisions.
The distinction matters because Batch Zero is a transitional, system-wide study for large loads that meet maturity and commitment criteria. ERCOT’s June implementation notice says the process is intended to evaluate reliability effects, allocate available transmission capacity among studied and committed loads, and produce an actionable transmission plan where feasible.
A classification is not an interconnection approval or an energization date. Conditionally included projects still have verification requirements, and projects that fail their conditions can be removed from Batch Zero.
Two different ways to contest a result
Public reporting describes different routes for two different outcomes. Treating them as one generic “appeal” would obscure the most important procedural distinction.
| Project outcome | Published route | Timing supported by the reviewed sources |
|---|---|---|
| Submitted as Base Load, then reclassified as Studied Load | Batch Zero dispute and reconciliation process | Service provider notification within two business days; dispute deadline within three business days of notification |
| Excluded from Batch Zero | ERCOT Alternative Dispute Resolution (ADR) | The reviewed sources confirm the route but do not state a filing deadline |
For reclassified projects, the three-day period is the clearest documented deadline. Baker Botts describes “tight three-business-day deadlines” running from notification. Reporting on ERCOT’s update says the transmission or distribution service provider must notify the affected customer within two business days.
For excluded projects, the same reporting identifies ADR as the relief route. It does not establish that an excluded project uses the same three-day deadline, files through the same intermediary, or receives any particular outcome. Those details should come from the project’s notice, ERCOT, its service provider or qualified counsel—not from inference.
The 14-day evidence period is a separate exception
The 14-business-day period is easy to misread as an appeal extension. It is narrower.
Some requests submitted under the energized-load eligibility path did not qualify under that provision but might qualify under another section. ERCOT planned to seek a separate Public Utility Commission of Texas exception for those applicants. If that pathway applies, the customer and its service provider receive 14 business days to provide new evidence.
That evidence window does not replace the three-business-day dispute period for a Base-to-Studied reclassification, and the reviewed sources do not describe it as a general option for every excluded project.
What the public material does not establish
The available notices and reporting do not support a universal checklist of documents, a prescribed email or mailing method, a fixed ADR deadline, or guaranteed outcomes such as restoration to Base Load. They also do not show that a successful classification challenge guarantees megawatts, queue priority, an interconnection agreement or an energization date.
That limitation is important for data-center developers. The classifications can affect queue position, financial-security obligations, study requirements and timing, but they remain one stage in a larger interconnection process.
A careful response to a classification notice
A project team can act quickly without inventing procedure:
- Confirm the exact classification and the date the customer received notice.
- Determine whether the project was reclassified or excluded; the published routes differ.
- Ask the responsible transmission or distribution provider to identify the controlling notice and submission channel.
- Preserve the project records relevant to the stated reason for the decision.
- Obtain project-specific regulatory or legal advice before a deadline expires.
ERCOT’s June implementation notice directs stakeholder questions to its Large Load Working Group feedback channel and tells market participants to contact their ERCOT account manager or Client Services. Those official contacts are more reliable than an inferred filing recipe.
Bottom line
The defensible public guidance is concise: reclassified projects face a three-business-day dispute window after notification; excluded projects have an ADR route; and a separate 14-business-day evidence period may apply only to a limited good-cause-exception pathway. None of those routes turns a conditional Batch Zero classification into permission to energize.
