What long-outage AES Indiana filings show
AES Indiana is an investor-owned utility operating in Indiana under EIA identifier 9273. It reports service to approximately 523,392 customer accounts and generated about $1.52 billion in annual electric revenue, with a service footprint spanning 82 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 AES Indiana customer experienced 466.8 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. Over the same period, SAIFI (outage events per customer) was 1.38, putting the typical customer at roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 86.7 minutes; the difference from the headline 466.8 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 AES Indiana, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 154.7 to 466.8 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
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 AES Indiana sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, AES Indiana charges more per customer than 70% of them, and is more reliable (lower SAIDI) than 21% 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: $2,914/year · Latest SAIDI: 466.8 minutes/year.
