NERC’s biennial grid-attack simulation—GridEx—is pulling in a wider slice of the energy ecosystem as cyber and physical threats grow more complex. (Utility Dive)
Participation jumped nearly 50%, driven mostly by small and mid-size utilities. These operators make up ~70% of the new entrants—a sign that the exercise is finally reaching the parts of the system most exposed to modern attacks.
With attacks rising and reliability margins tightening, DOE sees GridEx as essential “muscle memory”—a controlled environment to practice response before a real emergency hits.
