I'll add a quote from the article behind the following link to my previous comment.

Why you need to add solar to your emergency power backup plans

Earlier this year, the Wall Street Journal published an article summarizing a Senate hearing on the vulnerability of the electric grid. This study reviewed how a coordinated attack on only nine of the most critical sub-stations in the U.S. would cause a nation-wide blackout lasting up to 18 months. The hearing participants were strongly chastised for allowing this type of information to be made public.

yep ... the printing of secrets is a very profitable business.

That kind of attack can be accomplished without any kind of a control software hack. The vulnerability that article is about is not in the control software.
