You forgot about hospital equipment, ventilators in the home, etc.
The OP obviously doesn't realize that power cuts can kill people.

Power cuts can and do happen without cables being nicked. If that power is
essential, backup should be provided.

Hospitals always (?) have standby alternators, but what about, for
example, renal dialysis machines used in private homes?

For programmed shut-downs, mobile generators are usually provided . Kidney
machines are highlighted on operational control diagrams.

Why do you babble about something yo know nothing about?

General hospitals have their distribution systems divided into
essential and non-essential supplies. There is a (sometimes very
large) diesel generator starts up on power failure.
However this takes about sixty seconds.
Power failure is unusual because hospitals are commonly on the high
voltage ring main, it would take multiple faults to cause power
failure.
Three or four days worth of fuel is normally kept.
