Polk-Burnett Electric Coop is a member-owned electric cooperative operating in Wisconsin under EIA identifier 15344. It reports service to approximately 21,875 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 26 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 Polk-Burnett Electric Coop customer experienced 117.4 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. Over the same period, SAIFI (outage events per customer) was 1.30, putting the typical customer at roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 40.5 minutes; the difference from the headline 117.4 shows how much of the outage total came from weather rather than everyday grid issues.
Polk-Burnett Electric Coop has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI dropped from 209.4 to 117.4 minutes across that span, a direction regulators and prospective customers tend to watch closely.
