Five comment windows close today, ten routine filings come due between Wednesday and Friday, and a NERC standards window closes on Monday, August 31. Sixteen deadlines in all this week.

Corrected November 7, 2026. The first version of this edition said thirteen comment windows closed this week, called the Attachment W revisions new that week, and left out other open electricity windows. This version lists them, corrects the counts, repairs the revision request links, and describes the 161 as tracked items rather than open ones.

The through line: today, before anything else

Of the sixteen comment windows closing this week, five close today, Monday, August 24, among them the Storage Reliability and Flexibility Initiative and BP 7700 RFP Criteria Points Weighting. A comment not filed today on any of the five is a comment not filed. The rest of the week belongs to routine docket traffic, and the month closes out with a single NERC deadline.
