What mid-pack Perennial Public Power Dist filings show
Perennial Public Power Dist is a municipally-owned utility operating in Nebraska under EIA identifier 21111. It reports service to approximately 7,658 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 27 ZIP codes. Municipal ownership means a local board or city council typically oversees this utility, and it is exempt from federal income tax.
In 2023, the average Perennial Public Power Dist customer experienced 128.1 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. The SAIFI figure, which tracks average outage events per customer, came in at 1.01 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 87.0 minutes, the gap between that figure and the headline 128.1 reveals how much weather, not day-to-day infrastructure, drove outages.
Perennial 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 climbed from 40.9 to 128.1 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
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.
