The grid is generally not vulnerable to EMP. EMP will do far more damage to electronics. Solar events will not damage electronics other than those directly attached to long lines (i.e. nothing in your house).
The federal study done a few years ago says there will be extensive damage to the grid.
“The grid is generally not vulnerable to EMP. EMP will do far more damage to electronics.”
The grid is chock full of eletronics. An EMP will bring the grid down, probably immediately. EMP resiliency efforts are focused on how quickly the grid can be brought back up after that. It could be a long time.
