What short-outage Prairie Energy Coop filings show

Prairie Energy Coop is a member-owned electric cooperative operating in Iowa under EIA identifier 15291. It reports service to approximately 4,325 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 43 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 Prairie Energy Coop customer experienced 74.2 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. SAIFI, the average number of outage events per customer, was 0.51 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 41.9 minutes; the difference from the headline 74.2 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 Prairie Energy Coop, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI dropped from 100.3 to 74.2 minutes across that span, a direction regulators and prospective customers tend to watch closely.
