A federal appeals court has ruled that the United States Energy Department exceeded its authority when it ordered a coal-fired power plant in Michigan to remain open beyond its planned retirement. The decision on Friday marks a setback for the Trump administration's efforts to keep aging coal facilities operational.

The US Court of Appeals for the District of Columbia Circuit unanimously ruled that no emergency existed under federal law to justify keeping the 64-year-old J.H. Campbell Generating Plant online. Energy Secretary Chris Wright had invoked emergency powers the previous year, arguing the plant was necessary for regional electricity reliability.

President Donald Trump declared a national energy emergency in January of last year, citing increased demand from artificial intelligence and data centers. However, Judge Cornelia Pillard, writing for the three-judge panel, stated that the emergency provision of the Federal Power Act was intended as a "narrow, last-resort backstop." She explained that the authority could only be used when immediate action was required and states or utilities could not resolve the issue themselves.

Pillard also described the reversal of the plant's "long and carefully planned retirement" as "disruptive." The plant, operated by Consumers Energy, was originally scheduled to close in May 2025 but has continued operations under energy department orders. Financial filings indicate this continuation has cost approximately $259 million, with opponents expressing concern that these expenses could eventually be borne by families and businesses in the Midwestern United States.

Consumers Energy stated it is reviewing the court's ruling. Michigan Attorney General Dana Nessel, a Democrat, whose office joined counterparts from Illinois and Minnesota in challenging the orders, welcomed the decision. She asserted that the appeals court had "thrown out DOE’s order that had zero basis in reality."

The Energy Department defended its use of emergency powers, contending that the orders helped prevent blackouts and "likely saved hundreds of lives" during peak demand periods, especially during severe winter storms in late January and early February. The department reported that coal generation in affected areas increased by 25 percent compared to the previous year during the winter storm peak.

The Michigan case is one of several legal challenges that have arisen across the country. Notably, Secretary Wright issued another emergency order to a coal plant in Centralia, Washington, to remain in operation just hours after the ruling. Similar orders have been issued for plants in Indiana, Colorado, and Florida, underscoring a broader pattern of federal intervention in coal plant retirements.

This ruling raises questions about the extent of the Energy Department's emergency powers and the administration's broader strategy to support fossil fuel infrastructure against market and environmental pressures. The legal battles highlight the ongoing tension between energy reliability concerns and the transition towards cleaner energy sources.
