What mid-pack Oakdale Electric Coop filings show
Oakdale Electric Coop is a member-owned electric cooperative operating in Wisconsin under EIA identifier 13936. It reports service to approximately 18,650 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 30 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 Oakdale Electric Coop customer experienced 156.0 minutes of power interruptions, a metric called SAIDI (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. SAIFI, the average number of outage events per customer, was 1.17 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 95.6 minutes, and the spread against the headline 156.0 indicates how much weather, versus routine infrastructure, drove the outage total.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Oakdale Electric Coop, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 114.8 to 156.0 minutes, which may reflect either 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.

Price vs. reliability
Where Oakdale Electric Coop sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Oakdale Electric Coop charges more per customer than 36% of them, and is more reliable (lower SAIDI) than 56% of them, placing it in the quadrant where it pays less while still being more reliable, the best-value quadrant. Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
