NIPSCO Schahfer and CenterPoint Culley: What the Fourth DOE Order Actually Means for Your Bill

On September 20th, Energy Secretary Chris Wright signed the fourth consecutive Section 202(c) emergency directive requiring NIPSCO's Schahfer Units 17 and 18 in Wheatfield (combined roughly 847 megawatts) and CenterPoint's Culley Unit 2 in Warrick County to remain operationally available through December 18, 2026.

The problem buried in NIPSCO's own compliance filing: Units 17 and 18 are currently offline for significant turbine and boiler work. The DOE is invoking emergency reliability authority for units that cannot physically generate power right now.

Nine days before this renewal, the D.C. Circuit Court of Appeals vacated an identical order for Michigan's J.H. Campbell plant, ruling the DOE usurped state authority and that Section 202(c) was designed for short-term crisis response, not extended retirement delays. Legal challengers argue the same theory applies to the Indiana orders. That question is not yet resolved, but any challenge filed before December 18th puts it squarely in play.

On cost: NIPSCO's own FERC cost recovery filing puts Q1 2026 alone at $38 million (roughly $420,000 per day) with total projected costs potentially exceeding $100 million, socialized across MISO's industrial ratepayer base. That includes your facility if NIPSCO serves it. The Sierra Club estimates roughly $174,000 per day in ratepayer costs; NIPSCO has not confirmed that figure and its methodology has not been publicly disclosed.

December 18th is not a conclusion. It is a legal and financial checkpoint. Get someone modeling your MISO capacity cost exposure before that date.
