What long-outage Northern Indiana Pub Serv Co filings show
Northern Indiana Pub Serv Co is an investor-owned utility operating in Indiana under EIA identifier 13756. It reports service to approximately 488,841 customer accounts and generated about $1.65 billion in annual electric revenue, with a service footprint spanning 162 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 Indiana Pub Serv Co customer experienced 320.0 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that lands within the usual 120–180 minute national benchmark band, roughly on par with typical U.S. distribution-utility performance. The SAIFI figure, which tracks average outage events per customer, came in at 1.14 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 149.0 minutes; the difference from the headline 320.0 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 Northern Indiana Pub Serv Co, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 473.0 to 320.0 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.

Price vs. reliability
Where Northern Indiana Pub Serv Co sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Northern Indiana Pub Serv Co charges more per customer than 86% of them, and is more reliable (lower SAIDI) than 32% of them, placing it in the quadrant where it pays more but is LESS reliable, a premium price without a reliability payoff. Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
Revenue per customer: $3,381/year · Latest SAIDI: 320.0 minutes/year.
