Duke Energy Indiana
IOUNorth-central and western Indiana, including Terre Haute and Bloomington areas
Filed a major electric rate case in 2024 seeking recovery of transmission and generation investments; IURC approved a settlement with partial cost recovery and an extended depreciation schedule for the Cayuga coal plant. Ongoing scrutiny over coal-to-gas transition timelines under Indiana's integrated resource planning framework.
Indiana Michigan Power (AEP Indiana)
IOUNortheastern Indiana and a small portion of southwestern Michigan
Subject to IURC oversight on storm hardening and distribution automation investments under its TDSIC (Transmission, Distribution, and Storage System Improvement Charge) tracker. Has faced intervenor pushback on the pace of renewable procurement relative to legacy coal asset retirement.
Indianapolis Power & Light (AES Indiana)
IOUMarion County and surrounding central Indiana counties including Indianapolis metro
Rebranded under AES ownership; filed a combined electric rate case and integrated resource plan in 2024-2025 proposing significant solar and storage additions to replace Eagle Valley combined-cycle capacity. IURC proceedings have centered on cost allocation between residential and commercial classes.
Northern Indiana Public Service Company (NIPSCO)
IOUNorthern Indiana including Gary, South Bend, Fort Wayne, and Muncie areas
Executing an accelerated coal retirement roadmap under its 2021 IRP, with multiple renewable energy purchase agreements and the Dunns Bridge solar facilities under IURC review. Natural gas distribution rate cases have been filed concurrently, drawing attention to dual-utility cost recovery strategies.
Hoosier Energy Rural Electric Cooperative
coopCentral and southern Indiana, serving 18 member distribution cooperatives
As a generation and transmission cooperative, Hoosier Energy is not directly rate-regulated by IURC but faces state-level scrutiny regarding its coal plant exit strategy and whether stranded asset costs will flow through to member co-ops and their retail customers.
Citizens Energy Group
muniIndianapolis metropolitan area; provides natural gas, water, wastewater, and thermal energy
Unique hybrid structure operating as a public charitable trust; IURC regulates its natural gas and steam distribution. Recent regulatory focus includes water and wastewater infrastructure investment cost recovery and potential rate adjustments tied to EPA consent decree compliance for combined sewer overflow remediation.
Key Issues
- —
NIPSCO coal plant retirement and renewable transition: IURC is actively reviewing cost recovery mechanisms for NIPSCO's Schahfer and Michigan City unit retirements and associated replacement capacity contracts, with intervenors challenging whether ratepayers should bear full stranded asset costs under Indiana's CPCN process.
- —
AES Indiana integrated resource plan and rate case consolidation: The IURC is evaluating AES Indiana's proposal to retire fossil peaking units and add approximately 1,200 MW of solar and 200 MW of battery storage, with contested issues around capacity market participation, cost-of-service rate design, and environmental justice considerations in the Indianapolis service area.
- —
TDSIC tracker reform and infrastructure investment accountability: Legislative and commission interest in tightening oversight of Transmission, Distribution, and Storage System Improvement Charge trackers used by Duke Energy Indiana and Indiana Michigan Power, following audits suggesting some projects received automatic cost recovery without adequate prudency review.
- —
Natural gas distribution rate cases and decarbonization tension: Multiple gas LDC proceedings before IURC are raising questions about long-term pipeline infrastructure investment prudency given Indiana's evolving energy mix, with consumer advocates arguing against multi-decade cost recovery for assets potentially at risk of early obsolescence.
- —
Broadband-over-utility-infrastructure and pole attachment disputes: Increased filings before IURC related to pole attachment rates and access terms as electric cooperatives and IOUs navigate federal broadband funding deployment, with disputes over make-ready costs and timeline compliance under FCC and state frameworks.
Upcoming
Estimated IURC evidentiary hearing continuation for NIPSCO renewable energy purchase agreement docket; parties expected to present rebuttal testimony on capacity accreditation and long-term contract cost reasonableness (date estimated based on procedural schedule filed in early 2026).
Estimated deadline for AES Indiana to file updated integrated resource plan with IURC reflecting any revisions required following commission feedback in the consolidated rate case proceeding; solar and storage procurement timelines subject to revision (date estimated).
Estimated IURC final order anticipated in Duke Energy Indiana TDSIC Plan 8 proceeding, which covers approximately $380 million in distribution automation and grid hardening investments; outcome will set precedent for tracker oversight reform discussions in the 2027 legislative session (date estimated).
Estimated deadline for Indiana IOUs to submit triennial integrated resource plan updates per IURC Order 113306 schedule; NIPSCO, AES Indiana, and Duke Energy Indiana all expected to file revised IRPs reflecting updated load forecasts post-industrial customer additions and data center growth in northern Indiana (date estimated).
