******Update 12:30 Saturday 3/13******

We finished testing at 12:00 noon with no service interruptions. All of our critical infrastructure is operating normally.

The tests we performed once again demonstrate the unusual behavior and our electrical engineering firm was able to collect significant amounts of data from the generator and from multiple points on our electrical distribution system. They will evaluate it over the next week to identify the root cause of the unusual behavior we have observed and develop the necessary corrective actions.

We will reschedule the Seattle City Light high-voltage transformer upgrade once we have a clear understanding of the issue and have verified that the necessary corrective action has been taken and the result proven.

******Non-Impacting Facility Testing******

On Saturday, March 13th between 07:00 and 12:00 hrs. we will perform a number of tests on our emergency power system. These tests will not have any direct impact to the operation of the facility.

We have coordinated with our vendor partners, and will have a full compliment of df staff on-hand to investigate the issues we've experienced during Seattle City Light's attempts to upgrade the high-voltage transformer that supplies our facility.

We will cycle our automatic transfer switch (ATS) a couple of times during this window in order to provide facility load to our roll-up generator. Throughout this process, we will be monitoring our HVAC equipment and performing extremely detailed power quality monitoring on the generator power to help isolate the root cause of the unusual behavior we observed last Saturday.

We will provide an update here following the completion of these tests.
