Should utility companies be required to obtain community approval for all new local infrastructure projects?
Administrative law judges have recommended that the Illinois Commerce Commission reject ComEd's proposal for a new substation at 1111 W. Diversey Parkway. Officials determined the utility failed to adequately justify the scale of the project to meet neighborhood energy needs.
Why it matters
The recommendation marks a significant setback for ComEd, which maintains that the facility is critical to preventing future power outages in the region. Local residents and officials argue the proposed site is unnecessary and have offered several alternative locations for the utility to consider.
Administrative law judges reviewed opposition from the Diversey Community Coalition, which submitted over 1,000 public comments against the site. ComEd predicts 3% annual load growth, despite a 6% growth rate observed on the North Side from 2021 to 2025.
The players
ComEd
An electric utility company that provides power to Chicago and large parts of northern Illinois.
Illinois Commerce Commission
The state agency responsible for regulating public utilities including electricity, natural gas, and telecommunications.
Diversey Community Coalition
A local advocacy group representing residents in the area surrounding the proposed substation site.
Citizens Utility Board
A non-profit organization established to represent the interests of utility consumers in regulatory and legal proceedings.
Alderman Knudsen
A local elected official representing the district where the construction is proposed.
The details
The Citizens Utility Board argued the proposed five-transformer substation would far exceed actual power demand for the Lincoln Park area. ComEd has rejected 14 alternative sites identified by the community coalition and local representatives.
Timeline
North Side load growth reached 6% between 2021 and 2025.
A community rally and letter from Alderman Knudsen occurred in September 2026.
Administrative law judges released their filing recommendation in October 2026.
The Illinois Commerce Commission must act on the grid plan by December 15, 2026.
Market Landscape
This development tests the Illinois Commerce Commission's multiyear grid plan process as regulators weigh infrastructure necessity against localized pushback. The stalemate forces a confrontation between the utility's long-term grid strategy and community-led site alternatives.
The potential rejection of this substation could delay planned upgrades to local power capacity in the Lincoln Park neighborhood. Residents should monitor commission hearings for updates on how energy distribution strategies might change for their specific service area.
The takeaway
Large infrastructure projects often face intense scrutiny when utilities and local community interests diverge on projected power needs. Residents are encouraged to participate in public comment periods to ensure local neighborhood impact is considered in future utility planning.
What happens next
The Illinois Commerce Commission is scheduled to finalize its decision on the multiyear grid plan by December 15, 2026.
