Oakdale Electric Coop

What This Utility Data Tells You

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.
