Elk Riv4r,=�,** <br />- <br />Municipal Utilities UTILITIES COMMISSION MEETING <br />TO: <br />FROM: <br />ERMU Commission <br />Mike Tietz —Technical Services Superintendent <br />MEETING DATE: <br />AGENDA ITEM NUMBER: <br />May 14, 2024 <br />1.4 <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 245 public power utilities with <br />a "Certificate of Excellence in Reliability" for reliable performance. These utilities have <br />significantly outperformed the electric industry nationwide averages as gathered by the Energy <br />Information Administration. APPA collected data from public power utilities that subscribe to <br />APPA's eReliability Tracker software to track their reliability data. Of those utilities, 324 were <br />considered to have sound data that was included in the 2023 Annual Benchmarking Report. <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 />For 2023, ERMU's SAIDI was only 14.08 minutes (excluding major events), compared to the <br />industry average of 148 minutes (excluding major events). In simple terms, that means that <br />averaged out over our 13,543 electric customers in 2023, each customer could expect to have a <br />total outage time of about 14 minutes; that is 134 minutes shorter than the national average <br />for outages. <br />I would like to recognize the Elk River Municipal Utilities team for their continuous devotion to <br />provide reliable electric service to all our customers throughout 2023. This national recognition <br />is confirmation of the outstanding reliable service we provide each and every day. <br />/_A aLTSI:I►vi14►1111 <br />• APPA Certificate of Excellence in Reliability <br />Page 1 of 1 <br />3 <br />
