You might be able to hack in and look at your neighbors bill...
Understand that in the USA the grid is designed and operated by some of the most conservative people on the planet. They're just not sure about this computer fad thing.
They will take down the transformers....possibly destroy them in an attack. This would cripple the system for months.

The only thing a cyber attack could possibly do, assuming they can get thru all the multiple firewalls, is open Breakers and dump load. Utilities could island and manually use cold load pickup and restore the power, I mean their have been huge ice storms which essentially do the same thing!
What the bad guys could do is shoot armor piercing rounds thru the large high voltage transformers which are the back bone of the 345Kv system and above. these units have very little redundancy and a loss of a single unit is a major problem, note spares are not availble in most case and lead times are 3-4 yrs from receipt of PO. The pols worry about Cyber non-sense but that is not what would probably happen.
There are a number of mobile substations available in the USA. There are indeed spares and a damaged unit could be rewound within weeks with proper motivation. The armor piercing round has to get thru the tank wich is approximately 1/2 mild steel. Then several feet of oil. If it does manage to have enough energy to hit the windings it'll create a turn to turn short which is non critical.
Custom SCADA systems control the breaker open/close with little known proprietary protocols. It's not like the average IT geek hacker has any knowledge or access. Uti!ities have their own communication infrastructure. It would be very hard to get access.
Guys, the Grid can still function with major sections out. How else could we ever do maintenance? A grid with a double or triple point of failure would be useless.
But if there is this much fear, there may be an opportunity for me to do some consulting for serious bucks.
