A cyberattack on the U.S. electric grid could cause far more damage than Hurricane Sandy, a report says. Terrorists who gained access to any one of a number of key facilities could black out large regions of the nation for weeks or months.

The report recommends developing, manufacturing and stockpiling “universal recovery transformers” that could temporarily replace downed high-voltage transformers.”]
