They have two diesel generators. To test them, on saturday 
morning they fire them up and move every piece of equipment 
from Progress E to one generator and the next and back to 
Progress E, all while everything is on-line and running.

For Irene they ran for 4 days on diesel because the outside 
power was dirty/noisy/changing in voltage. So that the local 
people wouldn't be worried about their houses etc, the local 
people were sent home and a crew from Charlotte were brought 
in to run the place. I thought that showed a lot of respect 
for the workers. I also thought it pretty cool that the 
procedures in each place were identical and a crew from 
Charlotte could run the place without any familiarisation.

The last place I worked (NESC at EPA) had multiple 
contractors running each piece of the machine room 
(security, networking, power, job scheduling) so that you 
had no idea of the global picture. For the monthly diesel 
generator test, you were required to turn off your desktop 
machine incase it didn't survive the hash on changeover. You 
would be considered responsible if the machine was left on 
and didn't survive.
