12 Months Ending<br />
As seen here, for each of the rolling 12-month averages in 2005, CAIDI<br />
was consistently better than the established benchmark, ranging from 99 to 109<br />
minutes.<br />
The next two graphs show trends in the frequency of service interruptions<br />
for the PECO system from 1994 to 2005, and for the four quarters of 2005 and<br />
the first quarter of 2006, compared to the established benchmarks and standards<br />
for SAIFI.<br />
