Illinois Commerce Commission approves rehearing edits in ComEd time-of-use proceeding
Summary
At its July 17, 2025 open meeting in Springfield the Illinois Commerce Commission approved edited findings and rehearing in Docket 24-0378 related to ComEd’s proposed supply time-of-use (TOU) rate and revenue-neutral rate design under Public Act 102-0662. The commission directed further stakeholder outreach and a staff report ahead of a comprehensive cost-allocation review in January 2026.
The Illinois Commerce Commission on July 17, 2025 approved edits to an order reopening Docket 24-0378 and granted rehearing to evaluate Commonwealth Edison Co.’s supply time-of-use (TOU) rate proposal and related revenue-neutral rate design issues.
The chair introduced the order, saying it ‘‘initiates a rehearing to evaluate a voluntarily presented proposal for a supply time-of-use rate as requested and proposed by ComEd.’’ The edits approve ComEd’s proposed basic electric service time-of-use pricing and an opt-in supply TOU to be bundled with the company’s distribution TOU; the distribution TOU will continue to be offered as a standalone rate.
The commission’s edits note ambiguity in defining ‘‘revenue neutrality’’ under Public Act 102-0662 and say the commission will evaluate revenue neutrality specific to the statute’s objects and context. The order also finds the net implementation cost for ComEd’s proposal may be de minimis in the context of grid investments but stops short of making a final determination on whether an IDC waiver is necessary prior to development of customer outreach materials.
The chair moved the edits; Commissioner McCabe seconded. With no objections, the commission approved the edits and the order as edited.
The commission directed ComEd to collaborate with staff and stakeholders on customer materials and engagement. The order also states that after staff files a report on supply and delivery cost allocation issues in January 2026, the commission will undertake a comprehensive review of ComEd’s cost allocation procedures and address any needed modifications in subsequent proceedings.
Why it matters: The rehearing and the commission’s framing of ‘‘revenue neutrality’’ under Public Act 102-0662 shape how ComEd’s TOU proposals will be evaluated and the timeline for broader cost-allocation scrutiny. The January 2026 staff report and the subsequent review set milestones for possible changes to how charges are allocated between supply and delivery.
