The State Line Generating Plant was a coal-fired electrical generating station that operated from 1929 until 2012. It was located on the coast of Lake Michigan, bordering the state line separating Indiana from Illinois but within the corporate limits of Hammond, Indiana. In 2008–09, it had a year-round capacity of 515 megawatts.[1]
Most of the plant's exterior and some of its interior infrastructure dated back to its original operation in 1929, making this plant one of the oldest large-scale urban electrical generating stations in the United States at the time it ceased operations. The plant's age meant that it generated more toxic waste, such as airborne mercury and nitrogen oxides, than most other U.S. generating plants.[2]
Historically owned and operated by Commonwealth Edison, the State Line Generating Plant was later owned and operated by Dominion Resources. It was a National Historic Mechanical Engineering Landmark.[3][4] The plant reached the end of its operating lifespan and was permanently shut down on March 31, 2012.[5][6][7] Demolition was ongoing is November 2014.[8]
