UTILITIES COMMISSION MEETING <br />TO: FROM: <br />ERMU Commission Mike Tietz Technical Services Superintendent <br />MEETING DATE: AGENDA ITEM NUMBER: <br />April 14, 2020 1.7 <br />SUBJECT: <br />American Public Power Association Certificate of Excellence in Reliability <br />ACTION REQUESTED: <br />Receive the APPA Certificate of Excellence in Reliability <br />BACKGROUND \\ DISCUSSION: <br />The American Public Power Association (APPA) recently honored ERMU and 140 other public <br />power utilities with their Certificate of Excellence in Reliability. This recognition is given to <br />utilities that have significantly outperformed the electric industry nationwide averages as <br />gathered by the Energy Information Administration. APPA collects utility data from nearly 502 <br />public power utilities nationwide that track their reliability data via the eReliability Tracker. Of <br />those, 310 were considered to have sound data that was included in the 2019 Annual <br />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 the 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 compare, collect, <br />categorize, and analyze their outage information. <br /> <br />According to the numbers for 201925.41 minutes (excluding major <br />events), compared to the industry average of 143 minutes (excluding major events). In simple <br />terms, it means that averaged out over our 12,473 electric customers in 2019, each customer <br />could expect to have a total outage time that is 118 minutes shorter than the national average. <br /> <br />ATTACHMENT: <br />APPA Certificate of Excellence in Reliability <br />______________________________________________________________________________ <br />Page 1 of 1 <br />9 <br />
