I'm not seeing where in your article link it says every power company is connected to Internet.
That said, you have plant operation networks and the business side networks. As far as plant operation, I can't imagine a scenario where those networks go beyond the premises. i.e. Physical presence would be necessary to operate. There would be an air gap between any power infrastructure regulating/operating devices and any public wide area network. Now there could be a private OC-3 level connection between generation facilities. But that would also be private network that could only be infiltrated at the carrier level and would require nefarious hardware installation for ip communication, correct?
Going back to this attack specifically, if it is as truly widespread as is claimed, there are very likely players on the inside.
