What This Utility Data Tells You

Cass County Elec Coop Inc is a member-owned electric cooperative operating in North Dakota under EIA identifier 24949. It reports service to approximately 58,221 customer accounts and generated about $0.15 billion in annual electric revenue, with a service footprint spanning 60 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 Cass County Elec Coop Inc customer experienced 437.1 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, 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 0.83, putting the typical customer at roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 23.3 minutes, the gap between that figure and the headline 437.1 reveals how much weather, not day-to-day infrastructure, drove outages.

With 4 consecutive years of EIA data (2020–2023), Cass County Elec Coop Inc's reliability record can be judged on trend rather than one isolated year. SAIDI has increased from 47.8 to 437.1 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
