Otter Tail Power Co

What This Utility Data Tells You

Otter Tail Power Co is an investor-owned utility operating in Minnesota under EIA identifier 14232. It reports service to approximately 63,220 customer accounts and generated about $0.22 billion in annual electric revenue, with a service footprint spanning 420 ZIP codes. Because it is investor-owned, the state public utility commission oversees its rate cases and reliability performance rather than a local board.

In 2023, the average Otter Tail Power Co customer experienced 96.3 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. The SAIFI figure, which tracks average outage events per customer, came in at 1.38 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 96.3 minutes; the difference from the headline 96.3 shows how much of the outage total came from weather rather than everyday grid issues.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Otter Tail Power Co, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI dropped from 107.7 to 96.3 minutes across that span, a direction regulators and prospective customers tend to watch closely.
