Metropolitan Edison Company Met-Ed’s reliability performance summary was filed as a joint report submitted on behalf of the three Pennsylvania operating companies of FirstEnergy: Met-Ed, Penelec and Penn Power. On May 26, 2004, FirstEnergy filed a Petition for the Amendment of Benchmarks. 22 On February 17, 2006, the Commission entered an Order modifying the benchmarks and standards for the three FirstEnergy companies. Met-Ed’s CAIDI benchmark was decreased from 127 minutes to 117 minutes; the SAIFI benchmark was increased from 1.06 interruptions to 1.15 interruptions; and the SAIDI benchmark remained at 135 minutes. Met-Ed’s CAIDI for 2005 was 122 minutes, compared to 128 minutes in 2004, and five minutes greater than the benchmark. SAIFI, on the other hand, was 1.7 interruptions, compared to last year’s 1.54 and 23.2% over the standard. In 2005, Met-Ed’s service area experienced one major event. The calculation of the reliability indices exclude outage data related to this event, which was approved by the Commission: January 6 - 11, 2005: ice storm; 73,100 customers affected; 45,456,576 minutes excluded. For the 2005 calendar year, Met Ed filed five outage reports pursuant to 52 Pa. Code § 67.1, including one for the major event discussed above. In 2005, Met-Ed experienced 897,931 customer interruptions with a total duration of 110 million customer minutes, or 12.7% higher than 2004. The following graphs depict trends in the duration of service interruptions for the Met-Ed system from 1994 to 2005, and for the four quarters of 2005 and the first quarter of 2006, compared to the established benchmarks and standards. 22 Docket No. P-00042115.
