Marshall Steam Station
Encyclopedia
Marshall Steam Station is a coal power plant
located at 35°35′51"N 80°57′53"W in Terrell
, Catawba County
, North Carolina
, United States
and owned by Duke Energy
. Named for former company president E.C. Marshall, the station is located on Lake Norman
and began commercial operation in 1965.
Marshall is the second largest coal facility owned by Duke Energy in the Carolinas. It generates enough electricity
(2.09 GW
) to power
approximately two million homes.
The plant consists of four units. The first two, at 350 MWe
each, were launched in 1965 and 1966. The other two units, at 648 MWe each, were launched in 1969 and 1970.

s keeps the nitrogen oxide
emissions from the Marshall facility well below regulatory
limits. In 2004, Duke Energy began installing scrubber
s, which will lower the station's sulfur dioxide
emissions by approximately 95 percent. The project was completed in 2007.
