Dunn County Electric Coop

What This Utility Data Tells You

Dunn County Electric Coop is a member-owned electric cooperative operating in Wisconsin under EIA identifier 5417. It reports service to approximately 10,496 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 16 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 Dunn County Electric Coop customer experienced 105.1 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. Over the same period, SAIFI (outage events per customer) was 0.84, putting the typical customer at roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 78.5 minutes; the difference from the headline 105.1 shows how much of the outage total came from weather rather than everyday grid issues.

With 4 consecutive years of EIA data (2020–2023), Dunn County Electric Coop's reliability record can be judged on trend rather than one isolated year. SAIDI has increased from 67.8 to 105.1 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
