What long-outage Tri-County Electric Coop (MI) filings show

Tri-County Electric Coop (MI) is a member-owned electric cooperative operating in Michigan under EIA identifier 19396. It reports service to approximately 26,994 customer accounts and generated about $0.06 billion in annual electric revenue, with a service footprint spanning 110 ZIP codes. As a cooperative, its governance is accountable to its ratepayer-members rather than shareholders, which often shapes rate-setting and reinvestment priorities.

In 2023, the average Tri-County Electric Coop (MI) customer experienced 913.0 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. Over the same period, SAIFI (outage events per customer) was 1.06, putting the typical customer at roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 113.0 minutes, the gap between that figure and the headline 913.0 reveals how much weather, not day-to-day infrastructure, drove outages.

Tri-County Electric Coop (MI) has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. Over that span, SAIDI rose from 228.0 to 913.0 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
