Not all of it. Some designated as critical infrastructure is protected, private business can also be protected information.
The trick here is, most of the grid can compensate for outages and entire sections being lost. It's build to handle that. You can't just run out and bring down substations and transmission lines and knock out a city.
There's only some that are absolutely critical. Take Diablo Valley for example. Because they're nuclear and critical, they have an entire SWAT Team on hand and folks with .50 Cal Rifles on the roofs.
I wont speak to the security of this facility. I'll just say this, If someone got within 10 feet of the facility. It would be immediately known and responded in kind. There is no way, even digging a tunnel, someone would not be noticed.
Presumably everything is more robust now that lessons have been learned and single-point failures shouldn't have that sort of effect. Coordinated multiple failures most certainly will take down huge swaths.
