Northern Electric Coop, Inc

What This Utility Data Tells You

Northern Electric Coop, Inc is a member-owned electric cooperative operating in South Dakota under EIA identifier 13750. It reports service to approximately 6,717 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 35 ZIP codes. Cooperative ownership means the utility is run for the benefit of the ratepayer-members who elect its board, rather than for shareholder returns, which can shift how rate and investment decisions get made.

In 2023, the average Northern Electric Coop, Inc customer experienced 73.9 minutes of power interruptions, a measure known as SAIDI, or 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 0.67 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 54.2 minutes, and the spread against the headline 73.9 indicates how much weather, versus routine infrastructure, drove the outage total.

Northern Electric Coop, Inc has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has improved from 100.0 to 73.9 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
