An Examination of Vulnerabilities in the Electric Transmission Infrastructure of the United States
Despite the critical necessity of extra high voltage transformers and their obvious vulnerability to attack, little has been done to secure them. A visual examination of substations across the United States using Google Earth imagery clearly demonstrates that the vast majority of them are not shielded against attack. In fact, at most substations in the country, transformers can be readily seen through security fences within easy rifle range. In the event of a substation attack, it is also likely that backup transformers stored on site would be targeted.
