Indiana Michigan Power 2023 Rate Case

Indiana Michigan Power (I&M) is requesting a base rate increase in a newly filed case. The utility's request would raise annual revenues by approximately $116.4 million (6.8%). Under the proposed two phase rate increase the average bill for a residential customer using 1,000 kWh would rise by a total of $14.83.

All publicly filed documents in this case (Cause No. 45933) 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 attorneys and analysts are reviewing the utility's request. The case's procedural schedule includes a Nov. 15, 2023 deadline for the OUCC to file testimony.
  • Written public comments are invited through Nov. 8, 2023.

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

Previous Rate Cases

  • 2021-2022 Rate Case (Current Rates)

    The IURC set I&M's current rates on Feb. 23, 2022, approving a settlement agreement reached by the OUCC, I&M, and other parties in November 2021.

    In its initial case filed on July 1, 2021, I&M requested a two-phase rate increase that would have raised its annual operating revenues by $104 million (6.5%) and raised an average 1,000 kWh monthly residential bill using from $157.82 to $167.29 when fully implemented in 2023.

    The IURC held public field hearings in this case in South Bend and Fort Wayne. More information is available from the OUCC's Aug. 10, 2021 news release.

    The OUCC filed testimony on Oct. 12, 2021 recommending denial of the utility's request.

    All public documents in the case are available from the IURC's electronic document system.

  • 2019-2020 Rate Case

    The IURC approved I&M's previous base rates in March 2020, allowing an annual increase of $84 million. I&M had originally requested a $172 million increase.

    The OUCC's August 2019 news release summarizes the agency's testimony, in which the OUCC recommended an increase of less than $2 million.
