Regulators have approved a settlement that prohibits Duke Energy from passing on to consumers all the costs the company will incur building a coal-gasification plant in southwestern Indiana.
Costs for the plant in Edwardsport have increased substantially since it was proposed in 2007, and the latest estimate is $3.5 billion. Under the new agreement, Duke’s customers will pay nearly $2.6 billion for the plant, while the utility will be forced to absorb nearly $900 million in cost overruns.
