Midland Power Coop is a member-owned electric cooperative operating in Iowa under EIA identifier 12450. It reports service to approximately 12,416 customer accounts and generated about $0.05 billion in annual electric revenue, with a service footprint spanning 65 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 Midland Power Coop customer experienced 80.7 minutes of power interruptions, a measure known as SAIDI, or 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 1.03 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 80.7 minutes, the gap between that figure and the headline 80.7 reveals how much weather, not day-to-day infrastructure, drove outages.
With 4 consecutive years of EIA data (2020–2023), Midland Power Coop's reliability record can be judged on trend rather than one isolated year. SAIDI dropped from 898.2 to 80.7 minutes across that span, a direction regulators and prospective customers tend to watch closely. Note: this figure is unusually low compared to typical U.S. utility performance and may reflect an incomplete EIA filing for this year rather than a genuine reliability improvement -- treat with caution and cross-check against Midland Power Coop's other reported years.
