4r.;, <br />Elk Riv <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 />5.4 <br />SUBJECT: <br />2023 Annual Reliability Report <br />ACTION REQUESTED: <br />Receive the 2023 Annual Reliability Report <br />BACKGROUND: <br />Minnesota Rules Chapter 7826 Public Utilities Commission Electric Utility Standards cover <br />safety, reliability, service, and reporting requirements. Per 7826.0100(A), municipal utilities are <br />exempt from these requirements. However, the Elk River Municipal Utilities Commission <br />adopted several parts of this chapter as a Distribution Reliability Standard policy requiring <br />annual reporting on system reliability. <br />DISCUSSION: <br />In 2023, our reliability index numbers remain very good. These reliability index numbers reflect <br />the condition of our robust electrical system as well as the superb response time from our local <br />line crews. This also reflects the local accountability, long term visioning on system design, and <br />ongoing system maintenance. The table below reflects the number of customer outage minutes <br />for the last 10 years. <br />Year <br /># of Customers <br /># of Outage Minutes <br /># of Outages <br />2014 <br />9426 <br />243,965 <br />44 <br />2015 <br />9449 <br />225,337 <br />41 <br />2016 <br />10862 <br />432,310 <br />59 <br />2017 <br />11489 <br />354,625 <br />40 <br />2018 <br />12158 <br />117,055 <br />51 <br />2019 <br />12463 <br />312,885* <br />59 <br />2020 <br />12604 <br />197,884 <br />51 <br />2021 <br />13038 <br />628,670 <br />61 <br />2022 <br />13228 <br />174,500 <br />50 <br />2023 <br />13543 <br />187,469 <br />51 <br />*118,978 oft hese minutes are due to two separate transmission outages. <br />Page 1 of 3 <br />185 <br />
