Exceedance Probabilities and Recurrence Intervals for Extended Power Outages in the United States
Power outages cause significant economic and societal impacts. An increasing likelihood of extreme weather coupled with aging grid infrastructure is leading to a higher prevalence of extended power outages, which can leave customers without power for multiple days or even weeks. P...
