The cost to build Duke’s coal-fired plant in Edwardsport, Indiana was already about a billion dollars over original estimates.
Now the testing of new technology to burn coal more cleanly at the plant is taking longer than expected and adding $180 million to the cost.
Duke spokeswoman Angeline Protogere says this should be the last expensive delay for the Edwardsport plant.
“We believe this is a realistic cost for the project,” says Protogere.
