You will get far more familiar with this as more silly wind power is

I'm not overly keen on this frequency based automatic load shedding
(as in switching off) either. Sounds like a recipe for grid
instabilty if you ask me. Frequency drops, lots of stuff drops off
line, Whe Hey! too much capacity frequency goes up, stuff comes back
online, frequency drops...

And how much stuff is about that can be switched off for an
indeterminate period without warning?

I suspect that in the average household, not a lot but I have a friend who works for a water company and they regularly get paid for NOT pumping at certain times.
