System Resiliency & Physical Security

The U.S. electric system has become an integral part of our daily lives, so much so that we rarely consider how to live without it. The U.S. Department of Homeland Security, as directed by the White House, has identified the critical infrastructures in the United States. The current list includes 17 critical infrastructures with Energy at the top of the list. Indeed, the Department of Homeland Security has also noted that the remaining critical infrastructures require energy to operate. Of course, the electric grid, while highly reliable, was designed on the basis of serving electric customers, supporting electricity markets and serving industry’s needs. Today however, the electric grid itself is integral to our modern society and to our health, safety and welfare, and recent large-scale system events have focused attention on the resiliency of the electric grid in North America.
