Frequency - AIUI generate DC, and use some clever electronics to get it
on the grid. Not quite clever enough though...

I think we went to a small power station when I was at college doing
my HND in Electrical Engineering and I think they synched the
frequency of their output to that of the grid manually ... or hit the
big connection switch manually suggesting if they got it wrong by more
than a bit, it could rip the generators off their mounts?
