In order to perform urgent inspection and repairs on our Substation, one of our incoming National Grid feeders will be switched offline. We will be conducting switching to building feeds listed below between the hours of 4 am to 6 am Friday March 7th. This
will cause power losses from 1 to 10 seconds while we do switching. Emergency power circuits will see a loss similar to generator testing . ( Restoration interruption tentatively scheduled for Saturday March 15th 5 am to be announced in separate memo) </div>
