Umm... it’s my understanding that a celestial EMP event like a directed X-class flare would decimate anything electrical. We’re talking about a surge that would destroy anything with a current attached to it. Short of physically disconnecting the entire grid and shutting down the plants for the duration, I don’t know of any way to effectively prevent the destruction associated with something like this.
And let’s not forget the bigger problem we’d have: out of control satellites in orbit likely falling out of orbit and back to Earth.
The finger of God from Sol would be devastating in ways that we can’t possibly understand.

I think you’re confusing the effects of a “Carrington-like” solar flare with the effects of a nuclear EMP. Different animals, but both terrible to contemplate.
A big enough solar flare, a la Carrington, could knock out the electrical systems of every country on earth, unless adequate protection should be installed. But such a flare wouldn’t necessarily destroy electronic equipment that’s not connected to the electrical grid — even though one might question how useful the said equipment would be without a ready electrical supply!
On the other hand, a big enough nuclear EMP should destroy the electric grid WITHIN ITS FIELD, plus just about any solid state devices within its field that aren’t properly shielded and hardened. In the meantime, electrical and electronic equipment in the parts of the world outside the radiation field should escape damage.
And hundreds and hundreds of commercial and private aircraft.
