SPP cancelled the Resource Advisory it had declared for the East Balancing Authority Area from noon today until 8 p.m. CT, after a week in which binding constraints repeatedly cleared $1,000/MWh. On the docket side, nine comment and ballot windows close in the next seven days, and a complaint from Entergy Texas naming both MISO and SPP has arrived.

Corrected November 7, 2026. The first version of this edition said the East Balancing Authority Area advisory would run through the evening, but SPP cancelled it that morning. It also said seven comment windows closed this week, all of them routine per-docket filings, and left out other open electricity windows. This version lists them, counts the new ones among the week's arrivals, repairs the revision request links, and describes the 174 as tracked items rather than open ones.

The through line: the grid set the agenda

The operations desk owns the top of this edition. SPP cancelled the Resource Advisory for the East BAA at 8:53 a.m. CT today, due to improved system conditions, after a week of real stress: shadow prices above $1,000/MWh on four separate days, and the GSEC hub touching $923/MWh in the early hours of Saturday. Nothing in this section asks for a filing, but it is the context for everything that does.

The docket side supplied its own headline. Entergy Texas, Inc., et al. v. Midcontinent Independent System Operator Inc. and Southwest Power Pool.: Complaint of Entergy Texas, Inc., et al. was published 2026-09-24, and comments run to 2026-10-19.
