Northern Illinois Gas Co. v. The Illinois Commerce Commission

Petitioner appealed from a decision of the Illinois Commerce Commission in which the commission adopted an imputed capital structure for the petitioner, disallowed portions of the petitioner’s proposed pipeline investment costs, and required the petitioner to file a long-term gas infrastructure plan. The appellate court affirmed in part and vacated in part, affirming the commission’s orders adopting the imputed capital structure and disallowing a portion of the proposed distribution investment costs but vacating the order requiring petitioner to file an infrastructure plan. (PETERSON and BERTANI, concurring)
