To consider terrorist threat indicators in relationship to electric power substations, it is useful to understand the basic structure of the industry and what general types of facilities might be attractive targets for terrorist attack. Electric power substations are attractive terrorist targets because the loss of electric power has both direct and indirect impacts. Direct impacts include, for example, interruption of home and commercial building heating or cooling, damage to electronic data and equipment, the inability to operate life-support systems in hospitals and homes, and damage to the electric grid. Without electric power, other critical infrastructures, such as transportation, water supply systems, telecommunications, and banking and finance, cannot function. Indirect impacts may also include fatalities, injuries, and expenses related to failures in these interdependent infrastructures.
