Probability (peout) that the failure of a given power line is involved in three different modes of the power outage distribution for Hanna. S represents the southern community and W the western region in Texas. Modes are indicated by the insets, and the exact ranges of considered power outages are shown below these insets. Probability (peout) is calculated as the number of realizations having a total outage within the specified ranges in which the considered line fails, divided by the total number of realizations in the specified range. The different elements of the Texas power grid are coloured according to their respective outage probability. The probability distributions shown in the insets are identical to those shown in Fig. 1b.
