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 (%): 99.9922 <br /> Average eReliability Tracker ASAI 99.9829 <br /> Average ASAI for Utilities Within Your Region 99.9839 <br /> Average ASAI for Utilities Within Your Customer Size Class 99.9838 <br /> Table 11 <br /> Summary statistics of the ASAI data compiled from the eReliability Tracker <br /> Minimum Value 99.8427 <br /> First Quartile(25th percentile) 99.9814 <br /> 1Median Quartile (50th percentile) 99.9902 <br /> (Third Quartile(75th percentile) 99.9961 <br /> Maximum Value 99.9999 <br /> Figure 7 <br /> Average ASAI for all utilities that use the eReliability Tracker per region <br /> 99.995 - 99.993 <br /> 99.9906 <br /> 99.99 - 99.9873 99.9869 <br /> 99.985 - 99.9839 <br /> Q 99.98 <br /> Q 99.98 - 99.976 99.9766 <br /> 99.975 - 99.9724 <br /> Q' 99.97 - <br /> 99.965 - <br /> 99.96 , <br /> 1 2 3 4 5 6 7 8 9 <br /> Association Regions <br /> 8 <br /> 101 <br />
