It’s very fictional and was written to generate support for grants for certain individuals/groups to do more research.
Copied from a post I made on this subject not to long ago:
There are two and possibly 5 countries with the wherewithal do successfully pull off a hemp detonation IF it was not intercepted in route—one or a few missiles head this way you can bet that there will be enough countermeasures to stop or at least limit the damage...the norks are far from able to pull this off anytime soon
Also, emp effects are based on long circuits pushing up enough energy to fry stuff....power grid is vulnerable but most vehicles, even modern, would be largely unnaffected, as would generators and other electronics that are not plugged in
I know from personal experience parts of out power grid are protected with basically giant fuses and much of it would be brought back online fairly quickly
If you want something credible to worry about then worry about the c&c systems of the power grid, banking ssytem, and toher critical infrastructure being hacked...there is stuff there that should keep you from sleeping well

Yup, there's that too !
The main public concern has always been essential services, communication, and power supply which operates the infrastructure.
There has always been confrontation between the public sector and government administration, not over the need but over who is going to pay for the upgrade protection.
The discussion should have already been concluded as North Korea has already 'opened the barn door and let the horse out'. It's too late to close the door.

Well, I’ll tell you, the Northeast Blackout of 2003 showed how easily power disruptions can cascade.
The power grid going down is NOT something to be taken lightly.
