Watchdog warns Illinois customers may pay more after ComEd adds $1 billion in disputed electric grid costs

ComEd customers face a cost warning

ComEd customers in northern Illinois face an affordability warning as the Citizens Utility Board challenges the company’s proposed $15.3 billion grid plan before state regulators during formal 2026 review.

The watchdog says more than $1 billion needs closer review because some costs appear overstated, unsupported, or classified in ways that may limit stricter legal scrutiny in the case.

ComEd outlines future grid work

ComEd’s proposal covers planned grid work from 2028 through 2031, with the Illinois Commerce Commission reviewing whether the utility has justified investments for that four-year period under state rules.

The filing includes about $9.5 billion for infrastructure and about $5.7 billion for operations and maintenance, making affordability central before a later rate case addresses customer recovery questions directly.

Earlier rejection shapes the case

The Illinois Commerce Commission rejected ComEd’s earlier grid plan in 2023 after finding the utility had not proved the proposal was affordable for customers under state energy law.

That decision still matters because ComEd’s latest request is 21% larger than the approved amended plan, which followed changes regulators required to address customer affordability concerns in 2024.

Past reductions guide review

Regulators approved a revised plan after cutting ComEd’s proposed $2 billion spending request by about 25%, setting a comparison point for the pending grid-plan case under regulatory review.

The latest filing tests whether more reductions may be needed as households deal with higher costs for housing, groceries, and summer cooling across ComEd’s northern Illinois service territory.

Delivery service limits customer choice

ComEd operates as a regulated delivery utility, so customers cannot choose another company for local wires, reliability work, outages, and related electric service across its Illinois service territory.

Approved investments can later affect delivery charges, meaning disputed budget choices may reach monthly bills for families and small businesses across northern Illinois communities if regulators permit recovery.

Peak demand costs face questions

Citizens Utility Board says ComEd overstated peak-demand investments by about $238 million after passing over lower-cost options that can manage heavy usage during the hottest months of the year.

Those options include demand-response programs, which shift electricity use away from peak hours and may reduce the need for some distribution-system spending across ComEd’s grid in northern Illinois.

Fun fact: Electricity consumption in the USA, measured by residential utility purchases, averaged 10,791 kilowatthours in 2022, about 899 per month nationwide.

Smart meter costs draw scrutiny

Another disputed item involves $209.4 million to replace smart meters that the Citizens Utility Board says still work and have not yet been fully paid off through customer charges.

The meter proposal raises questions about timing, remaining value, and whether early replacement costs should stay in ComEd’s grid filing before the later rate case addresses future charges.

Little-known fact: Electric bills in the USA typically include a fixed monthly customer charge, a set amount charged regardless of energy usage.

Charging forecasts enter the dispute

Citizens Utility Board also questions $124 million in electric vehicle charging costs, arguing ComEd used assumptions that make expected load appear too high during peak periods in forecast models.

The watchdog cites electric school buses as one example because academic calendars may not match the hottest demand period used in ComEd’s charging load estimates for grid planning.

Spending labels carry weight

The classification dispute includes $96 million in capital spending that ComEd marked mandatory, although Citizens Utility Board says the projects were discretionary under the state review framework for utilities.

The watchdog also identifies $18 million in related operating expenses, saying those costs should face the same benefit review as discretionary grid work before any regulatory approval decision.

Illinois law sets a cost test

Illinois law requires grid plans to meet affordability, cost-effectiveness, and benefit standards, making classification central before regulators approve, modify, or reject proposed utility spending during formal plan review.

If regulators agree that items were misclassified, ComEd may need stronger support before those expenses can remain in the proposed grid plan during the 2026 regulatory review process.

Exelon pledge becomes case context

Exelon’s February pledge becomes case context because the parent company promised customer protections and fair cost sharing by large energy users during future grid planning for added demand.

Citizens Utility Board challenges ComEd’s forecasts, classifications, and spending levels through testimony in the Illinois Commerce Commission case record, while regulators weigh the proposed plan in 2026 proceedings.

Customer costs remain under review

Some grid upgrades may be needed, but Citizens Utility Board argues customers should not fund questioned spending, early equipment swaps, or planning based on extreme demand assumptions without support.

Regulators must also consider whether large new power users should cover more costs tied to the growth they create, rather than households and small businesses through future rates.

The case moves toward a ruling

The Illinois Commerce Commission is reviewing the proposal, with a proposed order expected in October and a final decision due by December 15, 2026, for the grid plan.

The ruling will determine which spending ComEd may include, whether disputed costs remain, and how the outcome affects customer risk before the separate 2027 rate case addresses charges.
