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. <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: 28.5464 28.5464 28.5464 0 <br /> Average eReliability Tracker Utility SAIDI 111.6347 67.8888 105.3348 6.2962 <br /> Average SAIDI for Utilities Within Your Region 55.4969 34.7555 52.7954 2.7015 <br /> Average SAIDI for Utilities Within Your Customer Size Class 87.1486 47.955 83.5351 3.6156 <br /> Table 3 <br /> Summary statistics of the SAIDI data compiled from the eReliability Tracker <br /> All No MEs Unscheduled Scheduled <br /> Minimum Value 0.2461 0.2461 0.2461 0 <br /> First Quartile(25th percentile) 18.6824 11.2111 18.6751 0 <br /> Median Quartile (50th percentile) 50.4729 25.1516 47.6868 0.0146 <br /> Third Quartile (75th percentile) 97.2444 56.433 91.815 0.701 <br /> Maximum Value 3128.437 3128.437 2974.7748 308.3812 <br /> Figure 3 <br /> Average SAIDI for all utilities that use the eReliability Tracker per region <br /> 300 - 281.861 <br /> m 250 - <br /> c <br /> E 200 - 175.5715 <br /> 0 <br /> 150 - <br /> a 102.863 101.8402 107.5171 92.1373 <br /> E$ 100 - <br /> cp 64.6299 55.4969 <br /> 50 - 41.2235 <br /> 1 2 3 4 5 6 7 8 9 10 <br /> APPA Regions <br /> 4 <br /> 55 <br />
