Our numbers reflect these major <br />outages and represent what our customers experienced in 2022. Overall, our electric <br />distribution system is very resilient, and our system reliability remains excellent. <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 />ACTION REQUESTED: <br />Staff requests the Commission receive and file the APPA eReliability Tracker 2022 Annual <br />Report for Elk River Municipal Utilities. <br />ATTACHMENT: <br />• APPA eReliability Tracker 2022 Annual Report for Elk River Municipal Utilities <br />Page 3 of 3 <br />182 <br />
