I read that it was the irregularity on the power grid which caused them
to shut down to protect themselves?

Sorry, don't know. But I thought this wasn't to do with software rather
hardware and the elements? I think it is a general upgrade of the grid
(and it's infrastructure) that is needed?

In Norway we only have hydroelectricity (well except
for the electricity we have to import during winter). The agecy for the
electricity in Norway said a blackout with the same magnitude (relative
to the size of the country and population of course) couldn't happen as
the grid was more desentralised. 

I'm more worried about east Europe nuclear plants and their
maintainance. And of course the heap of rusting Russian nuclear submarines
up in north Russia close to over border.
