Coal Creek Station
Location: Near Underwood, ND
Plant description: Coal Creek Station (CCS) is a lignite-based electric generating station with two pulverized tangential boilers. CCS provides baseload electric service, operating 24 hours a day, seven days a week. The Station is owned and operated by Great River Energy, headquartered in Maple Grove, MN.
Power production capability: This is the largest capacity power plant in North Dakota at 1,100 megawatts. The station has two units, each rated at 550 megawatts.
Plant history: Ground was broken for Coal Creek Station in the fall of 1974. The plant started generating electricity from Unit 1 in 1979 and from Unit 2 in 1980.
Environmental highlights: Great River Energy has invested in environmental equipment and controls for protecting land, air and water. Sulfur dioxide and particulates are removed from stack gases to meet or surpass North Dakota and federal air quality standards.
In 2009, Coal Creek Station completed the addition of new technology for reducing moisture content in lignite. Because the refined coal burns hotter and more efficiently, less coal is needed to generate the same amount of power, which results in fewer sulfur dioxide, nitrogen oxide, mercury and carbon dioxide emissions.
