Coal Creek
Location: ND
Operator: Great River Energy
Configuration: 2 X 550 MW
Operation: 1979-1981
Fuel: lignite
Boiler supplier: CE
T/G supplier: GE
EPC: Black & Veatch
Quick facts: This is North Dakota’s largest power plant. Ground was
broken in the fall of 1974. Coal Creek Station burns 7.5-8mn tpy of
lignite supplied by the adjoining Falkirk Mine. Electricity is delivered
to customers over a 436mi HVDC power line. The boilers are 205ft tall.
Since the power plant was built, approximately $200mn has been invested in
environmental equipment. Most fly ash is sold and in 2003, GRE built an
85,000t fly ash storage dome to ensure that an adequate supply is
available throughout the year. The plant will build a pilot
coal-drying facility. Since Mar 2007, Coal Creek has also supplied waste
heat for the operations of the new 50mn gpy Blue Flint Ethanol plant built
next to the power station.
