These utilities have <br />significantly outperformed the electric industry nationwide averages as gathered by the Energy <br />Information Administration. APPA collected data from nearly 509 public power utilities that <br />track their reliability data via the eReliability Tracker. Of those utilities, 272 were considered to <br />have sound data that was included in the 2020 Annual Benchmarking Report. <br /> <br />The tracker performs calculations for System Average Interruption Duration Index (SAIDI) which <br />measures the average outage time per customer on the system, System Average Interruption <br />Frequency Index (SAIFI) which measures how often a customer on our system could expect to <br />experience an outage, and Customer Average Interruption Duration Index (CAIDI) which <br />measures averaged outage duration of all customers that actually experienced an outage. <br />The report also includes calculations for Momentary Average Interruption Frequency Index <br />(MAIFI) and Average Service Availability Index (ASAI) which helps utilities to compare, collect, <br />categorize, and analyze their outage information. <br /> <br />For 2020, ERMU’s SAIDI was only 15.8 minutes (excluding major events), compared to the <br />industry average of 139 minutes (excluding major events). In simple terms, it means that <br />averaged out over our 12,604 electric customers, each customer could expect to have a total <br />outage time that is 123 minutes shorter than the national average. <br /> <br />I would like to recognize the Elk River Municipal Utilities team for continuing to provide our <br />customers with exceptional electric reliability in 2020. The hard work of these dedicated people <br />exemplifies ERMU’s Vision to “Provide exceptional services and value to those we serve.” <br /> <br />ATTACHMENT: <br />• APPA 2020 Certificate of Excellence in Reliability <br />2
