2026 University of Oregon Annual Electrical Testing Day

August 12th, 2026

CPFM Utilities and Energy will perform annual Island Mode testing on Wednesday, August 12th, 2026, between the hours of 8:00 am and 3:00 pm. Utilities and Energy staff will switch the entire campus in and out of Island Mode twice per hour (see full schedule below).  The first test will begin at the top of the hour, shifting off of EWEB’s electrical grid and onto our own power generation system (called Island Mode).  At 15-minutes after the hour, we will exit out of Island Mode and return back to EWEB’s power source.  This cycle will be repeated again at 30-minutes after the hour, re-entering Island Mode and 45-minutes after the hour when exiting Island Mode.  If problems occur during any of the planned island mode tests, power outages up to 10-seconds in duration may occur.
