|Duke Energy's Edwardsport, Indiana 'clean coal' plant|
The plant will be one of the most expensive nonnuclear power plants ever built in the U.S. The project had been intended to show how coal could be converted into a clean-burning gas and used to make affordable electricity, but its rising costs make that goal more challenging. The plant is expected to boost electricity rates in Indiana when it enters service next year.
Regardless of the plant's eventual price tag, state regulators have agreed to let Duke's Indiana utility charge customers for $2.35 billion of Edwardsport's cost. The Charlotte, N.C., company and the Indiana Utility Regulatory Commission are wrangling over the remainder, which tops $700 million. (WSJ, 10/21/2011)
