## Reviewed overview

R M Schahfer is a 1,105 MW natural gas fired combustion turbine, conventional steam coal plant in Jasper County. R. M. Schahfer Generating Station in Wheatfield, Indiana is owned by Northern Indiana Public Service Company (NIPSCO) and sits in MISO. It combines two coal-fired units of 423.5 MW each, Units 17 and 18, with a pair of 129 MW gas-fired units; the station's first units entered service in 1976. NIPSCO planned to retire the coal units in December 2025, but the U.S. Department of Energy has kept them available to operate through consecutive section 202(c) emergency orders, the latest running to December 18, 2026.
