Nipsco Indus. Grp. v. N. Ind. Pub. Serv. Co.

Citation: 100 N.E.3d 234Docket: Supreme Court Case No. 18S–EX–334

Court: Indiana Supreme Court; June 20, 2018; Indiana; State Supreme Court

Narrative Opinion Summary

This case involves a dispute between an energy utility and its largest industrial customers over the approval of infrastructure improvements under Indiana's TDSIC Statute. The utility sought to recover costs for projects through a seven-year plan with periodic rate adjustments, claiming that specific project designations were not feasible due to the unpredictable nature of infrastructure failures. The Industrial Group contended that the TDSIC Statute requires specific project designations in the initial proceeding, arguing that the utility's approach of using general project categories undermined statutory requirements. The Indiana Utility Regulatory Commission approved the utility's plan, leading to an appeal by the Industrial Group. The court ruled in favor of the Industrial Group, concluding that the TDSIC Statute mandates specific project designations at the outset, with no allowance for general categories to be approved later. As a result, the court partially reversed the Commission's order, remanding the case to ensure that only specifically designated projects are eligible for TDSIC recovery. The decision emphasizes the necessity for precise project identification to comply with statutory obligations.

Legal Issues Addressed

Interpretation of TDSIC Statute

Application: The court determined that the TDSIC Statute requires specific designation of projects in the initial seven-year plan and does not allow for general categories to be approved later.

Reasoning: The court concluded that multiple-unit projects described using ascertainable criteria are not eligible for TDSIC treatment, emphasizing that the TDSIC Statute requires projects to be specifically designated in a seven-year plan.

Preclusion Principles and Legal Reconsideration

Application: The court allowed the Industrial Group to challenge the TDSIC-4 Order, rejecting the argument that preclusion principles barred their appeal due to previous non-challenges.

Reasoning: The argument that claim and issue preclusion prevents the Industrial Group from appealing the Commission's TDSIC-4 order is rejected, as prior non-challenges do not preclude future legal scrutiny of the methodology employed in earlier orders.

Role of Section 9 Proceedings in TDSIC

Application: Section 9 updates are limited to documenting progress on approved projects and do not allow for new projects or budget changes in the seven-year plan.

Reasoning: Under Section 9 of the TDSIC Statute, updates cannot introduce new projects or alter the seven-year plan's budget once approved.

Statutory Criteria for Utility Plan Approval

Application: The Commission must approve a utility's plan if it is reasonable based on statutory criteria, including cost estimates, public necessity, and cost-benefit justification.

Reasoning: The Commission must approve a utility's plan if it is deemed reasonable, which is assessed based on three statutory criteria: the best-estimated cost of improvements, their public convenience and necessity, and the justification of their benefits through a cost-benefit analysis.
