NIPSCO CPCN 2017 - Coal Combustion Residual Rule and Effluent Limitation Guidelines


Sierra Club retained Synapse to analyze Northern Indiana Public Service Company’s (NIPSO) request for rider on $400 million in capital costs at three coal-fired power plants in Indiana (Bailly, Michigan City, and Schahfer) as they seek to comply with the United States Environmental Protection Agency’s Coal Combustion Residual (CCR) rule and Effluent Limitation Guidelines (ELG). In this docket, NIPSCO seeks to retire four coal-fired units (Bailly 7 & 8 and Schahfer 17 & 18) while retaining three units (Schahfer 14 & 15 and Michigan City 12). Synapse assessed NIPSCO’s economic analysis and supporting “qualitative assessment” and examined whether the retention of the three units would be in the interest of ratepayers, and if the company’s qualitative assessment was reasonably constructed. Dr. Jeremy Fisher filed testimony demonstrating that NIPSO’s ratepayers see $200-$600 million in benefits with the incremental retirement of Schahfer 14 & 15 and that the Company’s application does not support the decision to install retrofits at the units.
