System Average Interruption Duration Index (SAIDI) <br /> SAIDI is defined as the average interruption duration (in minutes) for customers served by the utility <br /> system during a specific time period. <br /> Since SAIDI is a sustained interruption index, only outages lasting longer than five minutes are included in <br /> the calculations. SAIDI is calculated by dividing the sum of all customer interruption durations within the <br /> specified time frame by the average number of customers served during that period. For example, a utility <br /> with 100 customer minutes of outages and 100 customers would have a SAIDI of 1. <br /> Note that in the tables below, scheduled and unscheduled calculations include major events. Also note <br /> that wherever major events are excluded, the exclusion is based on the APPA major event threshold. <br /> Table 2 <br /> Average SAIDI for all utilities that use the eReliability Tracker(with and without MEs), belong to <br /> your region, and are grouped in your customer size class <br /> All No MEs Unscheduled Scheduled <br /> Your utility's SAIDI: 41.0234 l 20.4977 40.9308 0.0926 <br /> Average eReliability Tracker SAIDI 92.3956 50.1741 87.6458 4.7532 <br /> Average SAIDI for Utilities Within Your Region 88.3391 36.6915 77.3377 10.9742 <br /> (Average SAIDI for Utilities Within Your Customer Size Class 85.4668 27.9804 83.2979 2.2003 <br /> Table 3 <br /> Summary statistics of the SAIDI data compiled from the eReliability Tracker <br /> All No MEs Unscheduled Scheduled <br /> Minimum Value 0.2845 0.2845 1 0.2845 0 <br /> First Quartile (25th percentile) 20.3321 10.2855 17.6174 0 <br /> Median Quartile (50th percentile) 51.9255 23.819 48.841 0.0486 <br /> Third Quartile(75th percentile) 108.162 49.0237 94.7276 0.887 <br /> Maximum Value 828.65 586.0228 828.6135 325.8937 <br /> Figure 3 <br /> Average SAIDI for all utilities that use the eReliability Tracker per region <br /> 160 - 145.1569 151.0079 <br /> 140 - 126.197 <br /> c 120 - 107.9024 <br /> E 100 - 88.3391 <br /> E <br /> 80 - 66.7488 68.8783 <br /> o) <br /> Elili <br /> - 49.3604 <br /> EL' <br /> 39 <br /> > - <br /> 1 2 3 4 5 6 7 8 9 <br /> Association Regions <br /> 4 <br /> 97 <br />
