What you explained is exactly what I have seen with regards to electrical designs in all hospitals I have worked in over the years.  

The larger hospitals will have as many as (12) diesel truck style motor/generators that will power all "red outlets" and lights in the entire hopsital.  All on automatic transfer switches.

There are also battery rooms that have enough capacity to power things for the few seconds it takes to switch over to generator.  All emergency medical gear has battery backups internal to itself, plus is in red outlets/generator power for emergencies.

I have seen cases where things don't work the way these should have have seen areas completely go dark, but that is rare and fortunately was never in clinical areas.
