US appeals court overturns emergency order keeping Michigan coal plant open

The unanimous ruling narrows Washington’s claimed emergency power over electricity generation and challenges a central tool in the administration’s effort to prolong coal-plant operations.

Court rejects the claimed emergency

A federal appeals court ruled on September 11 that the US Department of Energy exceeded its statutory authority when it required Michigan’s JH Campbell coal-fired power station to keep operating after its planned May 2025 retirement. The unanimous three-judge panel found that the circumstances did not amount to the kind of emergency contemplated by the Federal Power Act. Michigan, Illinois, Minnesota and environmental organisations had challenged the intervention.

The decision matters beyond one 64-year-old generating station. The administration has used emergency authority to delay the closure of several power plants around the country, arguing that dispatchable generation is needed to prevent electricity shortages. By treating that authority as a limited backstop rather than a general instrument of energy policy, the court has created a significant legal obstacle for similar orders affecting plants in other states.

A broader coal strategy faces a legal limit

The ruling cuts across an explicit White House strategy. In April 2025, President Donald Trump directed the energy secretary to accelerate the process for issuing emergency grid orders and to identify generating resources considered critical for reliability. A separate presidential determination in April 2026 classified coal supply chains and baseload generation capacity as resources essential to national defence, citing industrial demand and the electricity needs of artificial intelligence.

The Campbell extension also carried a substantial financial dispute. The Guardian reported that keeping the plant open beyond its scheduled retirement had produced about $259 million in costs, based on financial filings, while opponents argued that Midwest households and businesses would ultimately bear those losses. Those cost estimates and pollution claims came from litigants and campaign groups; the court’s central holding concerned statutory authority and the absence of a qualifying emergency.

What comes next

The immediate operational consequences will depend on implementation of the judgment and any further request by the federal government for rehearing or Supreme Court review. The larger test is whether Washington can justify other plant-retention orders on materially different grid conditions. Utilities, state regulators and consumer advocates will also watch whether the administration shifts from emergency directives toward ordinary reliability proceedings, where evidence, costs and alternatives receive a fuller regulatory examination.
