Marshall Steam Station is a four-unit, coal- and natural gas-fired generating facility located on Lake Norman in Catawba County, N.C. Named after former Duke Power President E.C. Marshall, the station is one of the largest power-generating facilities owned by Duke Energy in the Carolinas. The station generates enough energy to power approximately 2 million homes. In 2021, the company will complete construction activities to bring natural gas to the station to allow 50% natural gas co-firing on units 3 and 4 and up to 40% natural gas co-firing on units 1 and 2. For every pound of coal displaced with natural gas, sulfur dioxide will be reduced by an estimated 99%, and carbon dioxide emissions will be reduced by about 40% per megawatt-hour.
