length of outage was 119.32 minutes. Electric utilities with a high percentage of underground <br /> 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 2013, birds and animals caused the greatest <br /> number of outages. Birds and animals resulted in 29.03% of our outage incidents, and <br /> contributed to 4.93%of total outage time. Outages resulting from branches and/or trees made up <br /> 0.00% of our outage incidents and contributed to 0.00% of our outage time. This low percentage <br /> is a reflection of the good tree trimming our crews do during the winter. Overall, weather related <br /> outages accounted for 16.12% of the incidents and 83.26% of our outage time. Many investor <br /> owned and cooperative run utilities "storm normalize"their reliability numbers by removing <br /> "major outages"due to storms from their reliability index number calculations. Our reliability <br /> numbers have not been storm normalized. Our numbers reflect these major outages and <br /> represent what our customer actually experienced in 2013. Overall, our electric distribution <br /> system is robust and our reliability is very high. <br /> APPA compares our utility with other public power utilities in region 3. In comparison: <br /> Average SAIFI for all utilities that use the eReliability Tracker, belonging to our <br /> region, and are grouped in our customer size class <br /> Our utility's SAIFI: 0.0505 <br /> Average SAIFI for Utilities Within our Region 0.6304 <br /> Average SAIFI for Utilities Within Your Customer Size Class 1.0026 <br /> Our utility's SAIDI: 5.97 <br /> Average SAIDI for Utilities Within our Region 214.0614 <br /> Average SAIDI for Utilities Within our Customer Size Class 201.0751 <br /> Our utility's CAIDI: 118.23 <br /> Average CAIDI for Utilities Within our Region 168.5448 <br /> Average CAIDI for Utilities Within our Customer Size Class 161.156 <br /> Our utility's ASAI: 0.9999999 <br /> Average ASAI for Utilities Within our Region 0.9995927 <br /> Average ASAI for Utilities Within our Customer Size Class 0.9996174 <br /> I plugged this year's numbers in the above tables to compare with APPA's numbers. This year <br /> our outages will be submitted to APPA throughout the year and they will include them in the <br /> tables. We will be using the eReliabilty Tracker to record all of our outages going forward. <br /> ruin! � ► <br /> Page 3 of 4 NATUR <br /> power1e Public <br /> PoWBI ROVIEB( POWERED TO SERVE <br /> 177 <br /> • <br />
