What long-outage Great Lakes Energy Coop filings show
Great Lakes Energy Coop is a member-owned electric cooperative operating in Michigan under EIA identifier 38084. It reports service to approximately 131,726 customer accounts and generated about $0.23 billion in annual electric revenue, with a service footprint spanning 184 ZIP codes. Being member-owned, this cooperative answers to its ratepayers rather than outside shareholders, a structure that tends to influence how rate cases and capital spending get decided.
In 2023, the average Great Lakes Energy Coop customer experienced 265.2 minutes of power interruptions, a metric called SAIDI (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 1.69, putting the typical customer at roughly 2 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 202.5 minutes; the difference from the headline 265.2 shows how much of the outage total came from weather rather than everyday grid issues.
With 4 consecutive years of EIA data (2020–2023), Great Lakes Energy Coop's reliability record can be judged on trend rather than one isolated year. SAIDI dropped from 486.3 to 265.2 minutes across that span, a direction regulators and prospective customers tend to watch closely.
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 Great Lakes Energy Coop sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Great Lakes Energy Coop charges more per customer than 5% of them, and is more reliable (lower SAIDI) than 36% of them, placing it in the quadrant where it pays less and is less reliable. Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
Revenue per customer: $1,748/year · Latest SAIDI: 265.2 minutes/year.
