What long-outage Upper Peninsula Power Company filings show
Upper Peninsula Power Company is an investor-owned utility operating in Michigan under EIA identifier 19578. It reports service to approximately 53,271 customer accounts and generated about $0.12 billion in annual electric revenue, with a service footprint spanning 77 ZIP codes. As an investor-owned utility, it operates under state public utility commission oversight that reviews rate cases and reliability performance.
In 2023, the average Upper Peninsula Power Company customer experienced 425.1 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that lands within the usual 120–180 minute national benchmark band, roughly on par with typical U.S. distribution-utility performance. The SAIFI figure, which tracks average outage events per customer, came in at 1.58 for the same period, meaning customers statistically saw about 2 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 140.6 minutes; the difference from the headline 425.1 shows how much of the outage total came from weather rather than everyday grid issues.
Upper Peninsula 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 292.9 to 425.1 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.
