NIPSCO Industrial Group v. Northern Indiana Public Service Co.Annotate this Case
The Supreme Court affirmed the order of the Indiana Utility Regulatory Commission approving two complex, multi-year settlements regarding rates and infrastructure investments under the TDSIC Statute, Ind. Code ch. 8-1-39, holding that Appellant, a party to and proponent of the settlement agreements, was estopped from raising this challenge and that the Commission's order contained sufficient findings.
The agreements in this case specified how, in the utility's period petitions to the Commission, rate increases should be calculated and allocated among the utility's various rate classes. Despite being a party to the underlying agreements, Appellant, a group of some of the utility's largest industrial customers, opposed the utility's second periodic petition. Specifically, Appellant argued that the utility's rate calculation and allocation based on the underlying agreements was contrary to the TDSIC Statute. The Commission largely approved the utility's petition. The Supreme Court affirmed, holding (1) Appellant was estopped from challenging the terms of the settlement; and (2) the Commission's conclusion was reasonable and properly supported by specific findings.
