Illinois utility now being investigated following rate hike reduction – Center Square

In February, the commission began a separate investigation into Peoples’ pipe replacement program, which will continue through early 2025 and inform how the ICC directs the utility to cost-effectively remove cast iron and ductile iron pipe from its natural gas system.
