FOR IMMEDIATE RELEASE December 18, 202 5 PRESS CONTACT Cayli Baker O ff i c e: (312) 793 - 8841 Cayli.Baker @illinois.gov ICC issues decision on ComEd rate reconciliation Chicago, Il – The Illinoi s Commerce C ommission (IC C) struck $25.4 millio n from ComEd ’ s $268.5 million 2024 rate reconciliation request. T he decision is the first in a new performance- based evaluation p rocess desig ned to recon cile actual u tility spend ing with the approved investments out lined in the utility ’s multi - yea r grid and rate plan s. “ The ICC’s respon sibility is to balance th e interests of Illinois ’ utilities a nd their con sumers, and our new grid plan ning process is d esigned to h old the stat e’s largest el ectric ut ilities accou ntable for their performance,” said ICC Chairman Doug Scott. “The ICC’s decision today reiterates that unsupported departures from ComEd’s approved grid plan are inconsistent with the goals of the grid planning process, and it is the utility’s responsibility to prove that any adjustments made are reasonable and prud ent for main taining our p ower system. ” Today’s decision notably struck the bulk of overrun costs related to ComEd’s customer care and billing rollout last year, f inding that ComEd failed to pro ve the se costs were prudently incurred. The ICC removed performance incen tives for the mismanaged rollout. The decision also requir es ComEd to include affordability data updates and cost benefit analyses of related grid plan p rojects in futu re rate reconciliation docke ts to allow the ICC and relevant stakeholders to evaluate the impact of ComEd’s grid plan in r eal time. In 2024, the ICC approved ComEd’s revised grid plan to strengthen power grid reliability, support progress toward Illinois’ clean energy goals, and hold the utility accountable for meeting performance metrics set b y the Commission. In additio n to the electri c grid plan require ment, the Climate and Equitable Jobs Act (CEJA) subjects ComEd and A meren to performance -based evaluations in place of a preapproved formula rates. The ICC issued its decision af ter closely scrutiniz ing ComEd’s re concilia tion filing, a long with materials su bmitted by th e utility, ICC staff, and vario us interv enors over the course of an eight -month legal proceeding. In accordance with the Public Utilities Act, proposed costs are reco verable only when the utility demonstrates they are reasonable and prudent. In addition to tradition al standards u nder the Public Utili ties Act, the IC C evaluated ComEd’s actual costs using the cost - effectiv eness, coordin ated long term planning, equity, affordability, and transparency considera tions outlined in CEJA. The impact of the decision on individual customers will vary based on service class and energy usage. ComEd customers can e xpect these c osts to b e offset by a $8 03 million rebate approved earlier this month under CEJA’s carbon mitigation credit. Beginning January 2026, eligible customers can also qualify for ComEd’s low- income dis count program that provides tiered monthly discounts designed to r e duce energy bills to 3 to 6 percent of household income.
