Critical energy infrastructure encompasses the physical assets, digital networks, and operational technology essential for generating, transmitting, and distributing power. This includes generation facilities, transformer substations, high-voltage lines, smart grids, and centralized control hubs. Because modern societies and industrial economies rely on uninterrupted electricity, any severe disruption to these interconnected assets can trigger cascading failures across public transportation, water supply, healthcare, and communications. Consequently, protecting these assets forms the foundation of national resilience and public safety.
