INITIAL ALERTEmail
Northwestern Facilities Notification: An emergency electrical issue requires ComEd to perform repairs to the electrical infrastructure in the southeast portion of the Evanston campus. Power will be shut off at 4 p.m. today, Tuesday, October 22, in the following buildings: Norris University Center, University Library, Ryan Center for the Musical Arts, and the South Campus Parking Garage, among others. The outage is expected to last several hours. Please plan to relocate or end activities by 4 p.m.

The 15-minute warning before a planned 4 PM shutoff is unusually short — usually facilities notifications are sent at least a day in advance.

UPDATEEmail+4h 15m
ComEd repairs on south campus are ongoing. Power remains off at Norris, University Library, Ryan Center for the Musical Arts, and the South Campus Parking Garage. Evening events at affected venues are canceled. Faculty teaching evening classes in affected buildings have been notified directly. Restoration timing remains uncertain; current estimate is shortly before midnight. Schools and units will issue further guidance about overnight operations.

The decision to specifically name Norris (the student union) and the library — rather than just listing 'south campus buildings' — was driven by the practical reality that those two locations house most evening study traffic.

Context

Background

On the afternoon of Tuesday, October 22, 2024, an equipment failure on ComEd's distribution system forced an emergency repair on Northwestern's Evanston campus. ComEd cut power at 4:00 PM CDT to a cluster of south-campus buildings — including Norris University Center (the student union), the University Library, the Ryan Center for the Musical Arts, and the south parking garage — to allow crews to work safely. Norris and the library closed at 4 PM, evening events were canceled, and schools and units issued further guidance to faculty and students. Power was restored shortly after midnight Wednesday, an outage of roughly 8 hours. The incident was minor compared to UMD's 30-hour 2022 storm outage or Berkeley's 2024 multi-day outage, but it was a useful test of Northwestern's communication protocols for ComEd-driven incidents on a campus that does not own its substation.
