UTILITIES COMMISSION MEETING <br />TO: FROM: <br />ERMU Commission Mike Tietz –Technical Services Superintendent <br />MEETING DATE: AGENDA ITEM NUMBER: <br />April 14, 2020 2.7 <br />SUBJECT: <br />2019 Annual Reliability Report <br />ACTION REQUESTED: <br />Receive and file the APPA eReliability Tracker 2019Annual Benchmarking Report for ERMU <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 /> <br />DISCUSSION: <br />In 2019, 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 /> <br />Year # of Customers# of Outage Minutes # of Outages <br />20109207526,14477 <br />2011 9576 297,359 51 <br />2012 9285 71,496 57 <br />2013 9285 55,451 31 <br />2014 9426 243,965 44 <br />2015 9449 225,337 41 <br />2016 10862 432,310 59 <br />2017 11489 354,625 40 <br />2018 12158 117,055 51 <br />2019 12463 312,885* 58 <br />*118,978 of these minutes are due to two separate transmission outages. <br />______________________________________________________________________________ <br />Page 1 of 3 <br />52 <br />
