Elk River <br /> Municipal Utilities <br /> 13069 Orono Parkway phone: 763.441.2020 <br /> Elk River,MN 55330 Fax:763.441.8099 <br /> January 3, 2007 <br /> To: Elk River Municipal Utilities Commission <br /> Jerry Trkle <br /> John Dietz <br /> Jim Tralle <br /> From: Bryan Adams <br /> Subject: Electric Outage Report <br /> The Minnesota Energy, Security and Reliability Act enacted in 2001, contains a distribution <br /> reliability section. One section of this legislation requires, on an annual basis, an outage <br /> report be submitted to their governing bodies, which in our case, is the Elk River Municipal <br /> Utilities Commission. <br /> Your staff, for a number of years, has been documenting electrical outages to keep track of <br /> causes, number of customers out of power and for how long in an effort to track trends and <br /> resolve continued outage problems. This tracking now has the benefit of complying with the <br /> distribution reliability section of this legislation. Our electric outage reporting has been <br /> formalized so we can better track and analyze the number and causes of our outages. The <br /> attached two page spread sheet reflects the outage history for 2006. Animals (squirrels) and <br /> 3rd party dig-ins are the cause of the greatest number of outages. Construction issues (pole <br /> arm failure, slapping phase together while stringing, and wiring issue at Otsego Substation) <br /> caused the greatest number of customer minute outages at 75.1%. There is no alarming <br /> trends or patterns. <br /> The table below reflects the number of customer minutes outages from 2002 to 2006. <br /> YEAR # OF CUSTOMERS #CUSTOMER—MUNUTES OF OUTAGES <br /> 2002 6669 356,340 <br /> 2003 7193 39,285 <br /> 2004 7773 393,326 <br /> 2005 8398 558,140 <br /> 2006 8804 314,510 <br />
