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.

Information included in recent neighbor updates, along with work and progress at the site.



Oct. 6, 2017
Learn more about our emergency action plans for coal ash facilities. Ash basins continue to operate safely and are highly regulated. Removing water and permanently closing basins, work that is already planned or underway, adds an additional margin of safety. Inundation maps are planning tools that illustrate a worst-case scenario and depict the areas that could be impacted in the unlikely event of a complete dam failure.

2017 - 2018 

Work is underway to prepare for safely closing ash basins. This includes designing and constructing new retention basins for water management; installing state-of-the-art wastewater treatment systems; and installing new equipment to manage all coal ash dry rather than sending it to ash basins. While the work itself will occur on plant property, neighbors may notice periodic equipment deliveries and an increase in construction activities.

May - June, 2017 

As part of work to modernize electric generation in the region, crews are demolishing two smokestacks at the Marshall Steam Station that previously served Units 3 and 4. Neighbors may notice the stacks getting gradually shorter as the Mantis tool continues “chewing” down the stacks from top to bottom over the next few weeks. View image


Neighbor letter about landfill construction and site updates

March - April, 2017 

Duke Energy is constructing additional sections of the lined landfill along Island Point Road to continue safely managing coal ash. These new landfill sections are expected to be complete in late 2017.
