AES 2023 Rate Case

UPDATE (810/26/23): In addition to the rate case described below, the OUCC and CAC have filed a petition with the IURC requesting an investigation to assess AES Indiana's practices and procedures for storm outage restoration. The OUCC & CAC's joint July 12, 2023 news release has more information. On July 25, 2023 the OUCC filed a reply brief to AES Indiana's response and included over 40 consumer comments.

An IURC technical conference on the investigation request is scheduled for Oct. 2, 2023 at 9:30 am. It will be streamed live on the Commission’s website.

AES Indiana is requesting a base rate increase in a newly filed case. The utility's request would raise annual revenues by approximately 8.9% ($134 million). In its testimony, AES Indiana states that its request would increase the average bill for a residential customer using 1,000 kWh by $17.49 (13.2%).

All publicly filed documents in this case (Cause No. 45911) are available on the IURC's website.

  • The OUCC is the state agency - separate from the IURC - that represents all consumers in cases before the Commission.
  • OUCC staff are reviewing the utility's request and are scheduled to file testimony October 12.
  • Written comments from the public are invited through October 5, 2023.

Most rate cases take approximately 300 days to complete, and a final order from the IURC is not expected until Spring of 2024. The OUCC's timeline outlines the steps in the process.
