4 Definition of Reliability Performance Indices On the following page, ComEd provided 5 charts containing reliability indices for your municipality. CHART 1 - SAIFI (Average Number of Interruptions Per Customer) Chart shows the average number of interruptions per customer on an annual basis for your municipality for the past 5 years. For comparison purposes, this chart also shows the average number of interruptions per customer for the CornEd system. CHART 2- SAIFI Non-Storm (Average Number of Interruptions Per Customer) Same as CHART 1, however, reportable storms* have been excluded from the indices. CHART 3 - CAIDI (Average length of Customer Interruptions in minutes) Chart shows the average length of customer interruptions in minutes on an annual basis for your municipality for the past 5 years. For comparison purposes, this chart also shows the average length of interruptions for the CornEd system. CHART 4 - CAIDI Non-Storm (Average length of Customer Interruptions in minutes) Same as CHART 3, however, reportable storms* have been excluded from the indices. CHART 5- SAIFI by Cause Chart shows the average number of interruptions per customer by Interruption causes for the' past 3 years. Causes reflect 'interruptions' or 'outages' as defined by the General Assembly's Illinois Administrative Code Title 83: Public Utilities, Chapter I: lflinois Commerce Commission Subchapter c: Electric Utilities Part 411 Electric Reliability Section Definitions. "We recognize that storms can have a significant impact on the reliability. Indices. As a result, we also have computed these Indices excluding Interruptions during certain storms. To make these computations, we have used the 83 fffinois Administrative Code Part (a) reporting threshold (10,000 customers experiencing interrupt;ons for three hours) for determining when a "stormw has occurred Annual Franchise Report

5 Glossary of Interruption Causes Animal Related -Interruptions due to any type of wild or domesticated animal causing damage to material or equipment or making contact with energized overhead wires resulting in a short-circuit It must be apparent upon a normal field inspection that an animal was the root cause of the interruption.
