Northern Lights, Inc is a member-owned electric cooperative operating in Idaho under EIA identifier 13758. It reports service to approximately 18,917 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 40 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 Northern Lights, Inc customer experienced 291.1 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 0.4 minutes; the difference from the headline 291.1 shows how much of the outage total came from weather rather than everyday grid issues.
With 4 consecutive years of EIA data (2020–2023), Northern Lights, Inc's reliability record can be judged on trend rather than one isolated year. SAIDI has improved from 2205.3 to 291.1 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes. Note: this figure is unusually low compared to typical U.S. utility performance and may reflect an incomplete EIA filing for this year rather than a genuine reliability improvement -- treat with caution and cross-check against Northern Lights, Inc's other reported years.
