About Creating Performance Records that Exclude OMC Events

Some events, such as a power outage that occurred as the result of a thunderstorm, are not preventable. These types of events are considered to be outside management control (i.e., OMC events). Other preventable events, such as loss in generation capacity that resulted from an equipment failure or operator error are considered to be within management control.

All event data, regardless of its cause, must be reported to NERC. For internal tracking purposes, however, you may not be concerned with statistics associated with events that could not be avoided. Instead, you may want to review data associated with events that could have been avoided since these are the events from which strategies could be developed to prevent future, similar events. In other words, only the events that are within management control represent potential cost savings.

GE Digital APM provides you with the option of collecting a separate set of statistics for the events that are within management. To do so, you must complete two steps:

In GAA Unit records, set the Create Outside Management Control Statistics? field to True.
In any Event record that represents an event outside management control, set the OMC Event? field to True.

You can create two Performance records for each reporting month and year:

One record will include values from all Event records, regardless of the value in the OMC Event field in the Primary Event record that is linked to the Performance record. The Capacity History Statistics Type field in this Performance record will contain the value All Events.
The other record will exclude values from Event records in which the OMC Event field is set to True. The Capacity History Statistics Type field in this Performance record will contain the value Excludes OMC Events.
