As far as I understand this.."Hackers are taking the ultimate non-stop software ride along the US Power Grids, un-interupted by filters or Telephone Exchanges.
With the ultimate aim of disrupting the National U.S Electrical Grid system and its switchgear controls, in times of war.

This sounds like something out of a good Science Fiction story.
Except that the both the Chinese and the Russians have been caught, mapping the US power grid systems.
