Hurricanes, snowstorms, and other adverse weather events continuously inflict damage to the electric grid that costs between $20 billion and $55 billion annually. The loss of electricity from adverse weather events also generates social consequences. Given these consequences, different methods can be implemented to ensure persistent availability of electricity supply, including strategic investments in more robust grid infrastructure, active management of grid components, real-time grid condition monitoring and control as well as preemptive placement of repair crews before adverse weather events. In addition to these hands-on strategies, other approaches include the statistical analysis of past power outage data during adverse weather events. This top down statistical analysis offers a powerful way to identify recurrent patterns in the power outage data, which would then allow for a better understanding of the vulnerability of the ‘as built’ power grid.
