Southwest Power Pool (US)

A run of advisories in both the East and West balancing authority areas carries into this week, with a West Resource Advisory in effect today and an East one declared for tomorrow. On the stakeholder side, the comment window on Multi-Day Economic Commitment closes tomorrow, and 27 windows close in the next seven days.

Corrected November 7, 2026. The first version of this edition said 11 comment windows closed this week and 13 items arrived, and left out other open electricity windows. This version lists them, corrects both counts, describes the 170 as tracked items rather than open ones, and repairs the revision request links.
