AES 2025 Rate Case

AES Indiana's rate case is pending before the IURC in Cause No. 46258. The utility initially requested a $192.9 Million rate increase.

The OUCC's analysis shows that a $21.2 Million reduction to current base rates is warranted, based on the case’s evidence and applicable law. OUCC testimony is posted below and summarized in our Sept. 10, 2025 news release.

AES Indiana, industrial customers, Walmart, and the City of Indianapolis filed a settlement agreement with the IURC on Oct. 15, 2025.

  • The OUCC and the Citizens Action Coalition of Indiana are not parties to the settlement.
  • Additional OUCC testimony in opposition to the settlement is due on Dec. 12, 2025.
    • Written comments from the public regarding the settlement are invited through Dec. 5, 2025.
  • A settlement hearing took place in January 2026 and the settling parties submitted their proposed orders in February.
  • Any agreement before the IURC can be approved, denied, or modified. The settling parties have the burden of proof to show that an agreement is in the public interest.

UPDATE 6-17-2026: The IURC issued a final order on June 16, 2026 approving the settlement agreement with modifications. 

UPDATE 7-7-2026: The OUCC has filed for reconsideration and rehearing on the AES Indiana final order.
