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.

My point is that running those things is not free or cheap, and that with floating energy prices, you now have to make them significantly beefier and make economic decisions about when to run them. You will also have many more of these generators show up. People adapt their behavior to the incentives you give them, and the design of generators is also very much more subtle than you are giving credit for.

So yes, while it seems like people already have infrastructure for floating energy rates, in reality they do not.
