AES Indiana, IN
How often AES Indiana goes out
Indiana's grid here runs a bit rougher than most: 1.2 outages from AES Indiana in the most recent year, 4.9 hours total. That is 14% less outage time than the Indiana state average of 5.7 hours a year.
What a typical outage at AES Indiana looks like
Outages here average 4 hours before power returns. At that length, continuous fuel supply matters more than stored capacity, which favors a standby generator over anything battery-based. The frequency-versus-duration guide covers why length decides the kind of backup.
What this means for buying a generator
Serving 540,000 customers here, AES Indiana customers lose more power than most of the country sees, so a generator is worth getting rather than an overreaction.
The source behind this number
AES Indiana filed these numbers itself, as an investor-owned utility, under EIA Form 861 - a federal reliability report covering its entire Indiana territory, serving 540,000 customers here, not a single street or outage.
