What long-outage West Penn Power Company filings show
West Penn Power Company is an investor-owned utility operating in Pennsylvania under EIA identifier 20387. It reports service to approximately 597,758 customer accounts and generated about $1.02 billion in annual electric revenue. Investor ownership puts this utility under the regulatory authority of the state public utility commission, which reviews its rate requests and reliability record.
In 2023, the average West Penn Power Company customer experienced 420.0 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. SAIFI, the average number of outage events per customer, was 1.41 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 160.1 minutes, the gap between that figure and the headline 420.0 reveals how much weather, not day-to-day infrastructure, drove outages.
West Penn Power Company has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has increased from 258.3 to 420.0 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.
