Momentary Average Interruption Frequency Index (MAIFI) <br /> MAIFI is defined as the average number of times a customer on the utility system will experience a <br /> momentary interruption. <br /> In this report, an outage with a duration of less than five minutes is classfied as momentary. The index is <br /> calculated by dividing the total number of momentary customer interruptions by the total number of <br /> customers served by the utility. Momentary outages can be more difficult to track and many smaller <br /> utilities may not have the technology to do so; therefore, some utilities may have a MAIFI of zero below. <br /> Table 8 <br /> Average MAIFI 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 MAIFI: 0.0001 <br /> Average eReliability Tracker Utility MAIFI 0.463 <br /> Average MAIFI for Utilities Within Your Region 0.7759 <br /> Average MAIFI for Utilities Within Your Customer Size Class 0.3692 <br /> Table 9 <br /> Summary statistics of the MAIFI data compiled from the eReliability Tracker <br /> Minimum Value 0 <br /> First Quartile (25th percentile) 0 <br /> Median Quartile(50th percentile) 0 <br /> Third Quartile (75th percentile) 0.1539 <br /> Maximum Value 12.7241 <br /> Figure 6 <br /> Average MAIFI for all utilities that use the eReliability Tracker per region <br /> 1 - <br /> 0.9 0.8642 <br /> .9 <br /> 0.7759 <br /> 0.8 - <br /> Q 0.7 - 0.6227 <br /> 2 0.6 - 0.506 <br /> a) 0.5 - 0.4083 <br /> m 0.4 <br /> ¢' 0. - 0.1877 0.209 <br /> 0. 0 <br /> 1 2 3 4 5 6 7 8 9 10 <br /> APPA Regions <br /> 7 <br /> 58 <br />
