The purpose of this outage is to perform maintenance and testing on the major components of the main electrical switchgear, which distributes power throughout the 4444-Forest Park Building. To do this, Facilities Electricians will switch between the two utilities, which will allow them to keep the power on throughout the building while they work on the de-energized portion of the switchgear. Once all work is complete, the building will be returned to normal operation, with both ‘D’ & ‘W’ utilities energized. Facilities will perform switching between the ‘D’ and ‘W’ Utilities as necessary to perform work required for maintenance purposes. During the outage on Sunday, March 12th 7-11 am , the building will be single-sourced to one utility while the other is de-energized. We do not anticipate any interruption to power in the building.
