MiEnergy Cooperative is a member-owned electric cooperative operating in Iowa under EIA identifier 19157. It reports service to approximately 16,230 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 37 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 MiEnergy Cooperative customer experienced 42.5 minutes of power interruptions, a metric called SAIDI (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. Over the same period, SAIFI (outage events per customer) was 0.49, putting the typical customer at roughly 0 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 41.3 minutes; the difference from the headline 42.5 shows how much of the outage total came from weather rather than everyday grid issues.
With 4 consecutive years of EIA data (2020–2023), MiEnergy Cooperative's reliability record can be judged on trend rather than one isolated year. SAIDI has improved from 60.2 to 42.5 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
