5System Reliability

Reliability Performance IndicatorsReliability Performance Indicators

System Average Interruption Frequency Index (SAIFI) indicates how often the average customer experiences a sustained interruption over a predefined period of time

SAIFI shows an improving trend since 1998

ComEd’s 2010 year-end SAIFI performance of 0.94 is the fourth best on record

ComEd SAIFI has improved by 13% since 2001 and 33% since1998

2011 Year-End SAIFI projection 0.83, best on record.
