Update 7:30pm - Utility power was restored around 3:30pm today, and we have been off generator power since about 3:35pm. At 7:30pm grid power continued to be stable and hopefully will continue in that mode. We will continue to monitor the situation and are ready to resume an emergency power configuration if required.
Update 2:45pm - The generator fuel tanks have been topped off. We expect one more delivery later today.
If things continue as planned we should have sufficient fuel to get us well into tomorrow morning at which time we will deal with things according to current conditions.
So far the machine room has continued to operate without unplanned service interruptions, and that should continue as long as the fuel is flowing.
