Extreme Weather Event Analyses & System Hardening

In the past, it was not deemed economical to design distribution systems to withstand major weather events such as hurricanes, linear wind storms and ice storms. The expectation was that utilities would be prepared for timely customer restorations and repairs. Today, expectations have changed, and utilities are increasingly being expected to "harden" their system so that less damage occurs during such events. Efforts to “harden” the electricity grid must focus on two complementary and balancing elements: adaptation and survivability.
