Power to all Fermilab facilities and buildings — except the Village, Main Injector and accelerator facilities that are powered from the Kautz Road substation — will experience two brief interruptions on Monday, May 15. The first is scheduled to occur between 6:30 and 7 a.m. and the second between 5 and 5:30 p.m. The outages will allow ComEd to perform necessary maintenance on a primary switch serving the Master Substation.
Thunderstorms with lightning or other severe weather could alter the schedule. If that is the case, further communication will occur on Monday.
Prior to the outages, please power down computer equipment, and plan accordingly for elevators and lighting to be unavailable during the two time slots. Emergency systems will be operational during the outages.
