facilities will exhibit higher length of outage time than electric utilities with more overhead <br /> facilities. <br /> Staff reviews these statistics in detail to find ways to continually improve our system. These <br /> statistics are very good compared to other utilities. In 2014,birds and animals caused the greatest <br /> number of outages resulting in 31.25%of our outage incidents. Outages resulting from branches <br /> and/or trees made up 2.08%of our outage incidents. This low percentage is a reflection of the <br /> good tree trimming our crews do during the winter. Other contributing factors include: <br /> underground faults 16.67%; dig-ins, etc. 6.25%; component failure 4.17%; transformer failure <br /> 4.17%; fuse failure 10.42%; connector failure 12.50%; vehicle vs. pole 10.42%; and weather <br /> related outages accounted for 2.08%of the incidents. <br /> Many investor owned and cooperative run utilities "storm normalize"their reliability numbers <br /> by removing"major outages"due to storms from their reliability index number calculations. <br /> Our reliability numbers have not been storm normalized. Our numbers reflect these major <br /> outages and represent what our customer actually experienced in 2014. Overall, our electric <br /> distribution system is robust and our reliability is very high. <br /> Last year we were able to compare our numbers with APPA's national statistics by region. At <br /> this time we do not have those numbers; we expect to see them sometime next month. <br /> I've attached a recent article from The Resource, Official Publication of Minnesota Municipal <br /> Utilities Association, which features a local investor owned utilities reliability numbers that can <br /> be used for comparison. Also attached is a graph of our number of outages by cause. <br /> ACTION REQUESTED: <br /> No action is required. <br /> ATTACHMENTS: <br /> • The Resource—Xcel Files 2013 Safety, Quality, Reliability Report; MPUC Sets <br /> Standards for 2014-January 2015 <br /> • Graph of Elk River Municipal Utilities Number of Outages By Cause <br /> • <br /> OBEeED BY <br /> Page 3 of 3 <br /> [NATURE' <br /> Reliable Public <br /> Power Provider P 0 WE 0.E D T O S E 0.V E <br /> 62 <br />
