INDIANAPOLIS (AP) — The Indiana Court of Appeals ruled Monday that state utility regulators wrongly approved $61 million in ratepayer fees for the Edwardsport coal gasification plant.

Duke Energy is seeking the money to cover construction costs for the plant. But Appeals Court Judge James Kirsch wrote in Monday’s opinion that members of the Indiana Utility Regulatory Commission should have better analyzed arguments from Duke Energy and plant opponents before approving the fee increase.
