System Average Interruption Frequency Index (SAIFI) <br /> SAIFI is defined as the average number of instances a customer on the utility system will experience an <br /> interruption during a specific time period. <br /> Since SAIFI is a sustained interruption index, only outages lasting longer than five minutes are included in <br /> the calculations. SAIFI is calculated by dividing the total number of customer interruptions by the average <br /> number of customers served during that time period. For example, a utility with 150 customer interruptions <br /> and 200 customers would have a SAIFI of 0.75 interruptions per customer. <br /> Table 4 <br /> Average SAIFI for all utilities that use the eReliability Tracker, belong to your region, and are <br /> grouped in your customer size class <br /> Your utility's SAIFI: 0.3123 <br /> Average eReliability Tracker SAIFI 0.8515 <br /> Average SAIFI for Utilities Within Your Region 0.7275 <br /> Average SAIFI for Utilities Within Your Customer Size Class 0.8991 <br /> Table 5 <br /> Summary statistics of the SAIFI data compiled from the eReliability Tracker <br /> Minimum Value 0.0009 <br /> First Quartile(25th percentile) 0.2812 <br /> Median Quartile(50th percentile) 0.6357 <br /> Third Quartile(75th percentile) 1.0948 <br /> Maximum Value 8.0499 <br /> Figure 4 <br /> Average SAIFI for all utilities that use the eReliability Tracker per region <br /> 1 8 - 1.7043 <br /> 0 1.6 - <br /> . 1.4 - 1.3118 <br /> 1.2 - 1.1042 <br /> • 1 - 0.8483 0.9241 <br /> E (1.8 - 0.7409 0.7275 0.6949 0.6488 <br /> Q <br /> a) <br /> Cip 0.6 - <br /> 0.4 - <br /> Q 0.2 - 0 <br /> 1 2 3 4 5 6 7 8 9 10 <br /> Association Regions <br /> 6 <br /> 209 <br />
