Staff reviews these statistics in detail to find ways to continually improve our system. These <br />statistics are very good compared to other utilities. As indicated by the following pie chart and <br />statistics list, you can see the cause of the outages that we experienced in 2021. <br />Many investor owned and cooperative run utilities “storm normalize” theirreliability 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 customers experienced in 2021. Overall, our electric <br />distribution system is robust, and oursystemreliability is very high. <br />Please receive the attached American Public Power Association’s (APPA) eReliability Annual <br />Report which contains published averages that can be used to better understand the <br />performance of our electric system relative to other utilities nationally and to those within their <br />region or size class. <br />ATTACHMENT: <br />APPA eReliability Tracker 2021 Annual Report for ERMU <br />______________________________________________________________________________ <br />Page 3 of 3 <br />172 <br />
