What mid-pack Eastern Iowa Light & Power Coop filings show

Eastern Iowa Light & Power Coop is a member-owned electric cooperative operating in Iowa under EIA identifier 5605. It reports service to approximately 24,008 customer accounts and generated about $0.06 billion in annual electric revenue, with a service footprint spanning 81 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 Eastern Iowa Light & Power Coop customer experienced 184.0 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. 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 1.23, putting the typical customer at roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 103.1 minutes, and the spread against the headline 184.0 indicates how much weather, versus routine infrastructure, drove the outage total.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Eastern Iowa Light & Power Coop, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI dropped from 636.0 to 184.0 minutes across that span, a direction regulators and prospective customers tend to watch closely.
