My buddy in the energy field has the same response whenever this kind of article comes out.

"What makes you think that this article writer is the first person to have noticed this problem, and what do you think I do all day when I'm working to ensure you have power when you turn on the switch? We're always looking at what will go wrong, and preparing for when it does."

Even when Texas had the huge issues they did in 2021, the grid survived, and severe weather events impacting grid stability are more likely than both CMEs and EMPs.

Plus, it's amazing how undefended our energy infrastructure is against physical attacks, not just malicious actors. I've heard plenty of stories about the challenges related to squirrel-proofing substations.
