Nodak Electric Coop Inc is a member-owned electric cooperative operating in North Dakota under EIA identifier 12301. It reports service to approximately 21,123 customer accounts and generated about $0.13 billion in annual electric revenue, with a service footprint spanning 72 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 Nodak Electric Coop Inc customer experienced 302.2 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. Over the same period, SAIFI (outage events per customer) was 1.56, putting the typical customer at roughly 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 165.8 minutes, the gap between that figure and the headline 302.2 reveals how much weather, not day-to-day infrastructure, drove outages.
With 4 consecutive years of EIA data (2020–2023), Nodak Electric Coop Inc's reliability record can be judged on trend rather than one isolated year. SAIDI has increased from 240.0 to 302.2 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
