In 2023, the average Northern States Power Co - Minnesota customer experienced 168.4 minutes of power interruptions — a metric called SAIDI (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities.

Excluding major event days (hurricanes, ice storms), SAIDI drops to 83.5 minutes — the gap between that figure and the headline 168.4 reveals how much weather, not day-to-day infrastructure, drove outages.

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.
