What long-outage Southwest Electric Coop, Inc filings show
Southwest Electric Coop, Inc is a member-owned electric cooperative operating in Missouri under EIA identifier 27238. It reports service to approximately 43,991 customer accounts and generated about $0.07 billion in annual electric revenue, with a service footprint spanning 50 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 Southwest Electric Coop, Inc customer experienced 339.1 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That lands within the usual 120–180 minute national benchmark band, roughly on par with typical U.S. distribution-utility performance. Over the same period, SAIFI (outage events per customer) was 0.85, putting the typical customer at roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 217.0 minutes; the difference from the headline 339.1 shows how much of the outage total came from weather rather than everyday grid issues.
With 4 consecutive years of EIA data (2020–2023), Southwest Electric Coop, Inc's reliability record can be judged on trend rather than one isolated year. Over that span, SAIDI rose from 158.1 to 339.1 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.
