What mid-pack Southwest Public Power Dist filings show

Southwest Public Power Dist is a municipally-owned utility operating in Nebraska under EIA identifier 17692. It reports service to approximately 6,326 customer accounts and generated about $0.02 billion in annual electric revenue, with a service footprint spanning 21 ZIP codes. As a municipal utility, it is typically governed by a local board or city council and is exempt from federal income tax.

In 2023, the average Southwest Public Power Dist customer experienced 213.4 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. Over the same period, SAIFI (outage events per customer) was 1.03, putting the typical customer at roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 96.7 minutes; the difference from the headline 213.4 shows how much of the outage total came from weather rather than everyday grid issues.

Southwest Public Power Dist has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has increased from 99.4 to 213.4 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
