Both SPP balancing authority areas spent part of last week under a Resource Advisory, with constraints binding at shadow prices above $1,000/MWh into Monday. This week, 14 comment windows close, including two FERC Order No. 1920 interregional coordination addenda to SPP Tariff Attachment O.
Corrected November 6, 2026. The first version of this edition listed an October 16, 2027 comment deadline for the City of Pelican, AK notice. That notice asks for no comments; the date concerns the automatic renewal of an annual license. The first version also left out eight open windows. This version lists them, describes the remaining 163 as tracked items rather than open ones, and repairs the revision request links.
