What this does not establish
- 12 October 2026 is a response deadline, not an end date.
- ERCOT's report on the responses, which its information page says will be published by 10 December 2026, is not part of this record.
- The request is a one-time information request with a 12 October 2026 response deadline.
Unresolved questions
None recorded.
Relationships
Supersession means a later instrument replaces the earlier legal effect. Repeal links identify the repeal instrument and the measure it ends. A later implementation or related letter is not treated as a replacement unless the record says so.
