Everything the week asks of you is due by Thursday: a NERC standards window closes today, SPP's show cause order on transmission service to large load follows tomorrow, and the DPP Fee proposal closes Wednesday. Behind them, six windows land together on September 10.

Corrected November 7, 2026. The first version of this edition said seven comment windows closed this week, said the DPP Fee revision request arrived that week, and left out other open electricity windows. This version lists them, corrects the counts and the FERC-516 description, repairs the revision request links, and describes the 167 as tracked items rather than open ones.

The through line: done by Thursday

Eleven comment windows close this week, and every one of them falls between today and Thursday. After that the calendar goes quiet until Tuesday, September 8, then stacks up hard the following Thursday. If you plan to file anywhere this week, the work is front-loaded; if you plan to file next week, September 10 is the day to clear.
