Average Service Availability Index (ASAI) <br /> ASAI is defined as a measure of the average availability of the sub-transmission and distribution systems <br /> that serve customers. <br /> This load-based index represents the percentage availability of electric service to customers within the <br /> time period analyzed. It is caclulated by dividing the total hours service is available to customers by the <br /> total hours that service is demanded by the customers. For example, an ASAI of 99.99% means that <br /> electric service was available for 99.99% of the time during the given time period. <br /> Table 10 <br /> Average ASAI 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 ASAI (%): 99.9938 <br /> Average eReliability Tracker ASAI 99.9693 <br /> Average ASAI for Utilities Within Your Region 99.9808 <br /> Average ASAI for Utilities Within Your Customer Size Class 99.9561 <br /> Table 11 <br /> Summary statistics of the ASAI data compiled from the eReliability Tracker <br /> Minimum Value 99.0091 <br /> First Quartile(25th percentile) 99.9779 <br /> Median Quartile(50th percentile) 99.9896 <br /> Third Quartile(75th percentile) 99.9954 <br /> Maximum Value 99.9999 <br /> Figure 7 <br /> Average ASAI for all utilities that use the eReliability Tracker per region <br /> 99.9147 99.9761 99.9808 99.9894 99.9566 99.9121 99.9818 99.9849 99.9677 <br /> 100.00 <br /> ¢ 80.00 - <br /> u) <br /> m 60.00 - <br /> rn <br /> a) 40.00 - <br /> 20.00 - <br /> 0 <br /> 0.00 <br /> 1 2 3 4 5 6 7 8 9 10 <br /> Association Regions <br /> 9 <br /> 212 <br />
