Elk River <br /> Municipal Utilities UTILITIES COMMISSION MEETING <br /> TO: FROM: <br /> ERMU Commission Mike Tietz—Technical Services Superintendent <br /> MEETING DATE: AGENDA ITEM NUMBER: <br /> March 12, 2019 5.4 <br /> SUBJECT: <br /> 2018 Annual Reliability Report <br /> ACTION REQUESTED: <br /> Receive and file the APPA eReliability Tracker 2018 Annual 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 a number of parts of this chapter as a Distribution Reliability Standard policy requiring <br /> annual reporting on system reliability. <br /> DISCUSSION: <br /> In 2018, our reliability index numbers remain excellent. 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 <br /> minutes for the last 10 years. <br /> Year #of Customers #of Outage Minutes #of Outages <br /> 2009 9170 46,706 49 <br /> 2010 9207 526,144 77 <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 /> A number of reliability indexes are used in the electric industry to make it easier to compare <br /> performance of electric utilities.
