Not sure what KW we have at work. 100KW maybe? That's what I had at the cold storage. Just for backup lighting. Couldn't actually run any equipment on it. Same where I am now. Some of our freezer sites had trailer sized generators parked outside that could at least run some refrigeration. My larger plant had 5 NH3 compressors totaling 1550hp. I just closed all the doors and waited for the power to come back on.
