Item 9 Austin Energy Operational Update Q2 FY22 Austin Energy Utility Oversight Committee – May 2022 Sidney Jackson Chief Operating Officer, Austin Energy © 2018 Austin Energy 1 Discussion Topics Discussion Topics Performance Carbon Footprint On-Site Energy Resources Future State 2 Executive Summary Generator availability on target. For the quarter, resources meet availability targets, except where planned outages were experienced. Renewable production on target. For the quarter, aggregate quarterly renewable production as a percentage of load at 59%. Reliability benchmarks for the quarter, seasonably impacted by winter weather. Performance over the longer term, trending statistically consistent with top quartile industry benchmarks. Carbon free production on target. For the month of March, approaching 100% carbon free generation as a percentage of load. 3 Austin Energy Operational Update Performance 4 Commercial Availability & Start Success Commercial Availability Generation Resource Target Seasonal Commercial % Availability Commercial Availability Actuals (%) Q1 FY22 AVG Q2 FY22 AVG 76 44 51 84 98 55 97 100 * 95 95 97 100 Decker Steam Units Sand Hill Combined Cycle Fayette Units South Texas Project Start Success Commercial Availability values reflect maintenance or refueling outages typical for this period Start Success Target(%) Start Success Actuals (%) Q2 FY22 AVG Q1 FY22 AVG Simple Cycle Start Success 99 100 100 5 Net Generation and Load Analysis FY 2022 Q2 *Costs include fuel for generation, fuel transportation, renewable Power purchases agreements This information is unaudited and should be read in conjunction with the audited Comprehensive Financial Reports for the City of Austin, when published on 6 Resilience and Reliability are Austin Energy Strategic Goals • Distribution Grid Resilience Program o Wildfire Mitigation o Feeder Coordination • Reliability Strengths o Overall Distribution Reliability o Transmission System Performance • Opportunities for Improvement o Pockets of Poor Performance on the Distribution System o Substation Reliability • Current Improvement Initiatives o Improve Current Reliability Metrics o Address pockets of poor performance on the distribution system o Address poor substation performance 7 System Reliability 71.51 68.44 66.95 S A IDI w/o MED - CY19 - CY20 - CY21 - CY22 60.41 52.77 55.96 54.21 57.89 60.88 61.39 63.40 63.81 57.00 CAIDI = Customer Average Interruption Duration Index Average time to restore service SAIDI = System Average Interruption Duration Index Total duration of interruptions for the average customer, during a period of time SAIFI = System Average Interruption Frequency Index How often the average customer experiences a sustain interruption, over a period of time MED = Major Event Days 120 80 40 0 I E C V R E S E R O T S E R O T E M T I .
