What mid-pack Northern States Power Co - Minnesota filings show

Northern States Power Co - Minnesota is an investor-owned utility operating in Minnesota under EIA identifier 13781. It reports service to approximately 1,357,170 customer accounts and generated about $3.89 billion in annual electric revenue, with a service footprint spanning 500 ZIP codes. As an investor-owned utility, it operates under state public utility commission oversight that reviews rate cases and reliability performance.

In 2023, the average Northern States Power Co - Minnesota customer experienced 168.4 minutes of power interruptions, the industry-standard SAIDI metric (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. Over the same period, SAIFI (outage events per customer) was 1.06, putting the typical customer at roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 83.5 minutes, and the spread against the headline 168.4 indicates how much weather, versus routine infrastructure, drove the outage total.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Northern States Power Co - Minnesota, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 134.2 to 168.4 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
