What short-outage Alpena Power Co filings show
Alpena Power Co is an investor-owned utility operating in Michigan under EIA identifier 392. It reports service to approximately 16,750 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 11 ZIP codes. Because it is investor-owned, the state public utility commission oversees its rate cases and reliability performance rather than a local board.
In 2023, the average Alpena Power Co customer experienced 36.9 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. The SAIFI figure, which tracks average outage events per customer, came in at 0.46 for the same period, meaning customers statistically saw about 0 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 29.2 minutes; the difference from the headline 36.9 shows how much of the outage total came from weather rather than everyday grid issues.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Alpena Power Co, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI dropped from 213.5 to 36.9 minutes across that span, a direction regulators and prospective customers tend to watch closely. Note: this figure is unusually low compared to typical U.S. utility performance and may reflect an incomplete EIA filing for this year rather than a genuine reliability improvement -- treat with caution and cross-check against Alpena Power Co's other reported years.
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.

Price vs. reliability
Where Alpena Power Co sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Alpena Power Co charges more per customer than 23% of them, and is more reliable (lower SAIDI) than 91% of them, placing it in the quadrant where it pays less while still being more reliable, the best-value quadrant. Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
Revenue per customer: $2,115/year · Latest SAIDI: 36.9 minutes/year.
