Power Grid Vulnerabilities
• Physical:
- Over 450,000 miles of 100kV or higher (215,000 miles of 
230kV or higher) transmission lines, and many more 
thousands of miles of lower‐voltage lines

- Natural disasters or a well‐organized group of terrorists can 
take out portions of the grid as they have done in the U.S., 
Colombia, and other countries

- Effects typically confined to the local region.

• Open‐Source Information:
- Analysts have estimated that public sources could be used to 
gain at least 80% of information needed to plot an attack
