A federal court is declaring that the energy department exceeded its authority when it forced a Michigan power plant to stay open past its scheduled retirement date

In a defeat for the Trump administration, a federal court on Friday ruled that the energy department exceeded its authority when it forced a Michigan coal-fired power plant to stay open past its scheduled retirement date last year.

Energy secretary Chris Wright had said the 64-year-old JH Campbell Generating Plant was needed to ensure reliable electricity in the region, and he used emergency powers to keep it operating. Environmental groups and three states – Michigan, Illinois and Minnesota – went to court to try to overturn orders keeping the plant online.
