Utility Landscape

Commonwealth Edison (ComEd)

IOU

Northern Illinois including Chicago metropolitan area, serving approximately 4 million customers

Operates under a multiyear rate plan framework established by the Climate and Equitable Jobs Act (CEJA); subject to ongoing ICC scrutiny following a federal bribery scandal implicating parent Exelon's lobbying activities, with compliance and ethics conditions embedded in recent rate approvals.

Ameren Illinois

IOU

Central and southern Illinois, providing electric and natural gas service to approximately 1.2 million electric and 815,000 gas customers

Actively pursuing grid modernization investment recovery under its Integrated Grid Plan; filed a combined electric and gas rate case in 2024 seeking substantial base rate increases tied to infrastructure hardening and clean energy transition capital expenditures.

Nicor Gas (Southern Company Gas)

IOU

Northern Illinois suburbs excluding Chicago, serving approximately 2.2 million natural gas customers

Engaged in proceedings regarding pipeline safety cost recovery and leak reduction programs; faces increasing pressure from the ICC and interveners on methane emissions accountability and affordability impacts of capital trackers.

Peoples Gas Light and Coke Company

IOU

City of Chicago natural gas distribution

Under sustained ICC oversight due to the long-running and significantly over-budget System Modernization Program (SMP) for cast iron and ductile iron main replacement; cost disallowances and management audits have been central to recent dockets.

MidAmerican Energy Company

IOU

Northwestern Illinois, primarily the Quad Cities region, with electric and natural gas service

Maintains a relatively stable Illinois regulatory posture given its predominantly Iowa-focused operations; Illinois proceedings focus on gas distribution rate adjustments and integration of wind generation assets into its supply portfolio.

Illinois Rural Electric Cooperative (IREC) / Touchstone Energy Cooperatives

coop

Rural areas across central and southern Illinois, aggregating service through multiple distribution cooperatives

Generally exempt from ICC retail rate jurisdiction but subject to ICC oversight on certain interconnection and wholesale access matters; cooperatives are navigating CEJA renewable portfolio obligations and federal rural energy program funding under IRA provisions.

Key Issues

—
Peoples Gas SMP cost recovery and disallowance: The ICC continues to scrutinize whether Peoples Gas may recover remaining System Modernization Program capital costs given contractor mismanagement findings; a pending phase of the prudency review could result in additional disallowances exceeding $200 million and may set precedent for management audit-triggered rate exclusions.
—
CEJA multiyear rate plan implementation for ComEd: The ICC is administering ComEd's performance-based multiyear rate plan under CEJA, including annual revenue requirement reconciliations and performance metric evaluations; stakeholders are contesting the appropriate treatment of storm restoration costs and the calibration of equity metrics tied to customer affordability benchmarks.
—
Ameren Illinois combined electric and gas rate case: Ameren's pending base rate case seeks recovery of significant grid hardening, AMI expansion, and gas pipeline integrity capital; interveners including the Illinois Attorney General's Citizens Utility Board (CUB) are challenging the rate of return on equity and the inclusion of certain vegetation management and substation automation costs.
—
Renewable energy integration and interconnection queue backlog: CEJA mandates an aggressive clean energy buildout, but interconnection queue congestion at PJM and MISO is delaying Illinois utility-scale solar and storage projects; the ICC is engaged in coordination proceedings examining utility-side grid upgrades necessary to meet the 2040 carbon-free standard and whether upgrade costs should be socialized across ratepayers.
—
Natural gas decarbonization and future of gas infrastructure: ICC generic proceedings and legislative debate are intensifying around whether Illinois gas utilities should continue large capital investment in distribution infrastructure given potential stranded asset risk under CEJA's long-term carbon reduction trajectory; the ICC is evaluating gas utility integrated resource planning requirements and the regulatory treatment of renewable natural gas and hydrogen blending pilot programs.

Upcoming

2026-07-15

Estimated deadline for ICC initial order in Ameren Illinois combined electric and gas rate case (Docket Nos. 24-0263/24-0264); final briefs from major interveners including CUB and Illinois Attorney General's office anticipated in late June 2026 preceding this projected order window.

2026-08-01

Estimated ComEd annual multiyear rate plan reconciliation filing due to ICC under CEJA framework; filing expected to include Year 3 revenue requirement true-up, performance metric scorecards, and updated capital investment justifications for grid modernization programs.

2026-09-30

Estimated ICC final order in Peoples Gas SMP prudency review phase addressing post-2019 capital expenditure recoverability; outcome will determine whether additional SMP costs are excluded from rate base and may trigger management plan compliance requirements as a condition of future recovery.

2026-11-01

Estimated commencement of ICC generic proceeding on gas utility integrated resource planning and stranded asset risk assessment, anticipated following completion of a staff-led technical conference series on natural gas decarbonization pathways scheduled for summer 2026.
