What long-outage Upper Michigan Energy Resources Corp. filings show

Upper Michigan Energy Resources Corp. is an investor-owned utility operating in Michigan under EIA identifier 60631. It reports service to approximately 37,244 customer accounts and generated about $0.14 billion in annual electric revenue. 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 Michigan Energy Resources Corp. customer experienced 365.0 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That lands within the usual 120–180 minute national benchmark band, roughly on par with typical U.S. distribution-utility performance. Over the same period, SAIFI (outage events per customer) was 1.32, putting the typical customer at roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 187.0 minutes; the difference from the headline 365.0 shows how much of the outage total came from weather rather than everyday grid issues.

Upper Michigan Energy Resources Corp. 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 253.0 to 365.0 minutes, which may reflect either worsening weather exposure or delayed grid modernization.

Price vs. reliability

Where Upper Michigan Energy Resources Corp. sits on price vs. reliability

Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Upper Michigan Energy Resources Corp. charges more per customer than 91% of them, and is more reliable (lower SAIDI) than 28% of them, placing it in the quadrant where it pays more but is LESS reliable, a premium price without a reliability payoff. Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
