Coal Creek Power Plant is the largest power plant in the U.S. state of North Dakota. Located at near the Missouri River between Underwood, North Dakota and Washburn, North Dakota, it is the largest lignite-fired electricity plant in North Dakota. Its two generators are each rated at 605 megawatts (Unit 1 went in service in 1979, Unit 2 came online in 1980), with a peak total production of nearly 1.2 gigawatts.

The station is owned by Great River Energy, an alliance of Minnesota rural electric cooperatives, and trasmits its power to Minnesota over a 700 kilometres (430 mi) HVDC transmission line which is operated at +/- 400 kV. The line and plant were completed and put in service by 1981.

The Coal Creek Power Plant, part of the larger CU Project, was the subject of controversy.

The boiler building of Coal Creek Station is 89.91 metres high. Hereby the boiler is fixed to the roof. The chimney of Coal Creek Station is 198.12 metres tall.

Coal Creek Station is the third-largest producer of coal ash in the country, generating over four million pounds of surface waste stored onsite each year.

Some of the waste heat generated by the coal combustion is utilized by the nearby Blue Flint Ethanol plant.
