AES Indiana (Indianapolis Power & Light) — deep review (Indianapolis, Marion County, IN)

IBE Score: 5/10 · Category: Investor-owned electric utility · Headquarters: Indianapolis, IN · Reviewed: 2026-05-08

TL;DR

  • AES Indiana — the operating brand for Indianapolis Power & Light, owned by AES Corporation — serves about 510,000 customers across Marion County and parts of seven surrounding counties.
  • The IURC approved a $71 million electric rate increase in Cause 45911-IPL/AES Indiana (Phase II 2023), and AES Indiana’s reliability metrics during the August 2020 derecho and June 2023 derecho generated significant outage-related complaints.
  • On the positive side, AES has retired most of its coal generation (Petersburg conversions complete) and added the Petersburg Energy Center solar project — a meaningful clean-energy transition.

3. What the data shows

4. How they handle complaints

AES Indiana operates a published consumer-affairs process, with escalation to the IURC. Outage-credit and food-spoilage policies are narrowly defined and have generated complaints during major storm events. Bill-payment-assistance programs (Power of Change, LIHEAP coordination) are publicly documented.

5. IBE Score: 5/10 — reasoning

Decent customer-service responsiveness and a credible clean-energy transition; offset by urban-grid reliability issues and rate-case increases. 5/10 reflects a utility with visible improvement trajectory but unfinished work on reliability.
