The Indiana Office of Utility Consumer Counselor is seeking public comment on a Duke Energy coal-gasification plant in southwestern Indiana.

Indianapolis Power & Light Company received approval Wednesday from the Indiana Utility Regulatory Commission to convert another portion of its Harding Street Station from coal-fired to natural gas-fired.

Hallador Energy Co. announced the layoffs Monday affecting Sunrise Coal's mines in Carlisle and Oaktown, both about 90 miles southwest of Indianapolis.
