Peoples Gas System Modernization Program launch (2013)
Peoples Gas began replacing cast- and ductile-iron mains under Chicago. Cost estimates later rose from $2 billion to nearly $11 billion, according to CUB.
The ICC paused the program in 2023 after cost concerns.
The 2026 settlement removes $130 million in capital costs and adds bidding and cost-documentation rules.
The settlement credits stem from surcharges customers paid for this program.
