ICC approves ComEd supply time‑of‑use proposal as edited in rehearing

The Illinois Commerce Commission on July 17, 2025, approved edits to an order in a rehearing that accepts Commonwealth Edison Co.’s voluntarily proposed supply time‑of‑use (TOU) rate and approves company‑filed basic electric service time‑of‑use pricing. The commission said the STOU offering may be bundled with the company’s distribution TOU rate or offered as a stand‑alone rate.

The commission said the rehearing addressed a voluntarily presented proposal from ComEd and clarified that a specified statutory provision governing rehearing procedure did not require the company to offer the tariffed service. The commission’s edits reference Public Act 102‑62 and section 16‑105.5 of the Public Utilities Act in explaining how revenue neutrality should be evaluated in context and said parties had an opportunity to engage with the proposal under the agreed rehearing schedule.

The order states TOU rates can mitigate peak loads and customer bill increases and that consideration of customer benefits is appropriate to determining revenue neutrality under section 16‑105.5. The commission said the net implementation cost for ComEd’s proposed rate “may be de minimis in the context of grid investments” and that the record did not support delaying mandated initiatives. The commission also stated it would not make a final determination about whether an IDC waiver was necessary until customer outreach materials were developed.

The commission directed ComEd to collaborate with staff and stakeholders on development of customer materials and noted the company’s commitment to do so. The commission also reaffirmed that neither the Public Utilities Act nor commission rules prohibit regulated utilities or competitive market participants from offering a supply TOU.

Commissioners moved and seconded edits to the rehearing order and, with no objections raised on the record, approved the edits and the order as edited. The commission recorded no further contested proceedings on the rehearing at the meeting.

Background: The rehearing arose from docket 204378 and concerns ComEd’s revenue neutral rate design and proposed tariff changes. The commission’s edits emphasize statutory interpretation of revenue neutrality under Public Act 102‑62 and set expectations for ComEd’s outreach and stakeholder engagement going forward.
