Marshall Steam Station

Capacity: 2,090 megawatts
Location: Catawba County, North Carolina
Commercial Date: 1965
Status: Operating

Marshall Steam Station is a four-unit coal-fired generating facility located in Catawba County, N.C. Named for former Duke Power President E.C. Marshall, the station is located on Lake Norman.

One of the largest coal facilities owned by Duke Energy in the Carolinas, Marshall generates enough electricity to power approximately 2 million homes. Since it began commercial operation in 1965, Marshall Steam Station has been among the most efficient power plants in the nation.

Duke Energy has made significant improvements to reduce emissions from the company’s coal-fired plants. A unique type of burner arrangement in the boilers keeps the nitrogen oxide emissions from the Marshall facility well below regulatory limits.

In 2004, the company began installing flue gas desulfurization equipment – commonly known as scrubbers. This equipment will lower the station’s sulfur dioxide emissions by approximately 95%. The project was completed in 2007.
