IIIA. Sustained Outage Causes <br />In general, sustained outages are the most commonly tracked outage type. In analyses of <br />sustained outages, utilities tend to exclude scheduled outages, partial power, customer - <br />related problems, and qualifying major events from their reliability indices calculations. While <br />this is a valid method for reporting, these outages should be included for internal review to <br />make utility -level decisions. In this section, we evaluate common causes of sustained outages <br />for your utility, corresponding region, and for all utilities that use the eReliability Tracker.
