I know there are low-tech ways of crippling the electric power grid that are difficult to defend against. I'm much less familiar with what it takes to prevent cyber attacks but I believe it could be done easier than physically protecting facilities.
I wonder how much a general system backup can be used to restore access and functionality. At least a couple of days is somewhat bearable (see power safety shutoffs in CA - thanks PG&E!): we haven't invested in surge equipment that can handle a major solar event, which could knock out systems for months.
