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 (%) 99.998 <br /> Average eReliability Tracker ASAI 99.9615 <br /> Average ASAI for Utilities Within Your Region 99.9747 <br /> Average ASAI for Utilities Within Your Customer Size Class 99.9579 <br /> Table 11 <br /> Summary statistics of the ASAI data compiled from the eReliability Tracker <br /> Minimum Value 98.3359 <br /> First Quartile(25th percentile) 99.9731 <br /> Median Quartile(50th percentile) 99.9899 <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 /> 99.9554 99.9758 99.9747 99.8538 99.9399 99.9475 99.9803 99.9668 99.9742 <br /> 00.00!i1IIIIII !
