BREAKER BRIEF
WEEK OF OCTOBER 19 TO OCTOBER 25, 2026 | BREAKERBRIEF.COM
Southwest Power Pool (US)
SPP issued advisories for both its East and West Balancing Authority Areas in the middle of last week, and constraints bound at a shadow price of $500/MWh or more on every day from October 15 through early this morning. Twenty-one comment windows close in the next seven days, four of them today.
Corrected November 7, 2026. The first version of this edition said two comment windows closed this week and ten items arrived, and left out other open electricity windows. This version lists them, corrects both counts, describes the 168 as tracked items rather than open ones, and repairs the revision request links.
