Stop in for a cup of coffee

Think the only way we loose power this time of year is if the net goes down or to many workers not available for the maintenance on the grid.
I don't expect it to be a problem. But then none of this was expected...
I don't even know what the weak points of the system are. Most of the maintenance is a couple guys working in open air. So that is not a big issue. But how much control is done in a computer room somewhere? How much hands on control is even needed to keep it all going?
