In my post I was explicitly referring to backup generators being basically mandatory at a refrigerated pharmaceutical storage warehouse, not making a general argument that every industrial building should have backup generators. Generators are common at data centers, hospitals, emergency dispatch call centers, and refrigerated storage facilities.

There was no need to take a specific point I was making about refrigerated storage facilities and pretend I was talking about commercial and industrial sites in general. Please read more closely next time and respond to my actual argument instead of the argument you imagined that I made.
