ComEd asked the ICC to approve a $15.3 billion plan for delivery-system investments in 2028-2031. The plan does not set rates; ComEd estimates it would raise the average residential monthly bill by about $2.50-$3.00 per year starting in 2028, with a separate rate filing planned for January 2027. An ICC order is due by Dec. 15, 2026.

Utility's stated reasons

ComEd seeks $234.3 million to true up actual 2025 delivery costs against its approved rate plan. ComEd says this would still lower average residential charges by about $0.13/month in 2027 versus 2026; combined with a $128 million refund of 2025 over-collections (approved July 2026), the average bill would drop about $1.22/month in 2027.

Utility's stated reasons

  • actual 2025 grid operating and capital costs above the approved plan
  • customer-driven projects
  • state-mandated programs such as beneficial electrification

This affects the supply part of the bill for customers on ComEd's default supply, not delivery charges. ComEd said higher PJM capacity auction costs would raise the average residential bill by about $2 to $3 a month starting June 1, 2026. The summer 2026 Price to Compare is 10.399 cents/kWh (8.677 cents supply plus 1.722 cents transmission).

Utility's stated reasons

  • higher PJM capacity auction prices
  • demand growing faster than available generation

The ICC approved about $243 million of ComEd's $268.5 million request to true up 2024 delivery costs, striking $25.4 million, mainly overrun costs from the 2024 billing-system rollout.

  • 2024 spending above the approved grid plan budget
