In 2007, Duke Energy Indiana began construction of a 618 megawatt (MW) integrated gasification combined cycle power plant (IGCC).

The gasification process makes coal react with pure oxygen and steam to produce synthetic gas, or syngas.

Instead, Duke Energy Indiana would need to seek approval to construct a pipeline to transport carbon to a more suitable site.

Edwardsport's pollution per unit of energy produced will be greatly reduced, as particulate matter and mercury will be removed from the syngas.

The coal-derived synthetic gas is much cleaner than conventional coal combustion to begin with, and it is easier to clean to greater extent.

Thus far, the legal issues have resulted in the resignation of the second highest ranked executive for Duke Energy, the dismissal of the Chairman of the IURC, David Lott Hardy, and Hardy's subsequent indictment for three felony counts of official misconduct in cases concerning Duke Energy,[4] although the charges were dismissed on 12 August 2013.
