Comed Files 2028-2031 Grid Plan; BOMA/Chicago Intervenes for Members

Published by BOMA/Chicago on: March 16, 2026

ComEd has submitted its next Multi-Year Integrated Grid Plan to the Illinois Commerce Commission (ICC), outlining proposed investments and system needs for 2028–2031. The filing succeeds the current Grid Plan, which runs through 2027, and is intended to maintainsystem reliability while implementing equity goals and objectives of the Climate and Equitable Jobs Act (CEJA) and the Clean and Reliable Grid Act (CRGA).

Expected Cost Impacts for Commercial and Industrial Customers 

ComEd’s filing includes projected delivery rate impacts compared to 2024 levels: 

  • Commercial customers ( <1 MW hourly demand): Delivery charges are estimated to increase by 0.5 cents/kWh in 2028 and 0.9 cents/kWh by 2031. 
  • Industrial customers (>1 MW hourly demand): Delivery charges are estimated to increase by 0.04 cents/kWh in 2028 and 0.2 cents/kWh by 2031.

ComEd states that these increases reflect planned system upgrades, capacity expansions, and technology modernization efforts. 

Major Projects and Investment Areas 

ComEd identifies several categories of work needed to support load growth, reliability, and clean energy integration. Substations experiencing the largest growth are concentrated in dense urban areas, particularly the Chicago Central Business District, where limited space for distributed energy resources may require additional capacity investments. 

Key proposals include: 

  • Voltage optimization through coordinated feeder and substation upgrades (capacitors, regulators, sensing and control equipment). 
  • Modernization of legacy substations and feeders. 
  • Construction of new substations in high growth areas, including: 
  • West Side (East Garfield Park, Medical District, Fulton Market, United Center) 
  • Lakeview (Lincoln Park, north of the CBD) 
  • Van Buren (Loop/CBD) 
  • Elk Grove 
  • Franklin Park (O’Hare area) 
  • System reliability investments tied to operations and maintenance. 
  • Grid management programs, including real estate, fleet, training, and environmental needs. 
  • Customer operations and IT investments to support service delivery and system performance. 

BOMA/Chicago’s Intervention 

Given the potential impact on large commercial buildings, BOMA/Chicago has formally intervened in the ICC proceeding. Our participation will focus on ensuring that ComEd’s proposed spending, capacity expansions, and rate impacts are transparent, justified, and reflective of the needs of large building owners in Chicago’s urban core. 

We will monitor the case, evaluate cost impacts, and provide input where possible during the regulatory process to ensure that reliability improvements are balanced with affordability and operational realities for commercial properties.
