most supermarkets have standby generators

Which are tested how often, and run for how long? Also how long can individual branches continue if they're off-line from head office computers for reordering stock?

How long can farms go with no mains electricity for milking and milk cooling/storage? I know they usually have generators for short periods.

No water
No sewage.
Gravity will help

In some locations; far from all. Where gravity causes the sewage to run into the water supply, things could get very nasty very quickly.

No radio
Most radio transmitters have standby generators.

But do most people have battery radios any more?


They have cars with radios.
