The Illinois Commerce Commission (ICC) directed PGL in February 2025 to retire all cast- and ductile-iron pipes with diameters below 36 inches by January 1, 2035. PGL is pursuing the replacements through its Pipeline Replacement Program (PRP), with annual investment expected to increase to approximately $500 million in 2028. The requirement creates a substantial regulated infrastructure investment and cost-recovery exposure for the Illinois segment.
