Hoot Lake Fergus Falls, MN. Three coal-fired (western subbituminous) units and one hydroelectric unit. Owned by Otter Tail Power Company. Completed in 1948, 1959, and 1964, the coal-fired units have capacities of 8, 64, and 84 megawatts respectively. The hydro unit, which began producing electrity in 1919, generates slightly less than 1 megawatt.For more information, contact Otter Tail Power Company's Public Relations Department at 218-739-8297.
Sherburne County (Sherco) Generating Station; 2400 MW; Location: Becker, Minn., 45 miles northwest of the Twin Cities, on the Mississippi River. Plant Description: Sheer size sets the Sherburne County Generating Plant (Sherco) apart from the company’s other generating facilities. Sherco is the largest in terms of square feet, steam production, power generation capability and coal consumption. Power Production Capability: 2,400 megawatts (MW) , Unit 1 – 750 MW ; Unit 2 – 750 MW; Unit 3 – 900 MW Fuel Source: Low-sulfur Western coal from mines in Montana and Wyoming.

Allen S. King Generating Station; Location: Oak Park Heights, Minn., on the St. Croix River. Plant Description: Allen S. King is a single-unit coal-fired generating plant with a cyclone boiler. The unit provides base load electric service, operating 24 hours a day, seven days a week. Power Production Capability: 588 megawatts (MW) from one unit. Fuel Sources: Low-sulfur WY coal.
Black Dog Generating Station; Location: Burnsville, Minn. on the Minnesota River. Plant Description: Black Dog is a coal- and gas-fired generating station, located on the Minnesota River just south of the Twin Cities. The original Unit 1 boiler/turbine and the Unit 2 boiler, installed in the 1950s and fired on coal, recently were replaced with a natural gas combined-cycle unit (Unit 5), which includes a natural gas-fired turbine-generator combined with a heat recovery steam generator. Exhaust heat from Unit 5 powers the Unit 2 steam turbine. The repowering project, completed in summer 2002, boosts output from the two original units by more than 100 megawatts, and results in greater operating efficiency and cleaner power production. Units 3 and 4 are dual-fuel boilers with steam turbines that continue to utilize coal as the primary fuel. Natural gas is the backup or topping fuel used to obtain maximum generation for both units. Power Production Capability: (In-Service Dates) 538 megawatts: Unit 2 – 98 MW (1987); Unit 3 – 108 MW (1955); Unit 4 – 170 MW (1960); Units 5 (2002) – 162 MW. Fuel Sources: Low-sulfur western coal and natural gas.

Paul R. Tregurtha Interlake Steamship Co
Carrying Capacity: 68,000 Gross Tons Overall Length: 1,013.5' Official Number: 631688 Year Built: 1981
Hull Depth: 56.0' Beam: 105.0'
Engine Horsepower: 17,120 [Today, the core business goal of Fairbanks Morse Engine is to provide its customers with the highest quality diesel engines and generator sets, dual-fuel engine generator sets, and OEM parts and to back them all with world-class field service support. Primary markets include stationary power generation and marine propulsion.]
At 1013.5 feet, Interlake's flagship M/V Paul R. Tregurtha is the longest ship on the Great Lakes.
She can carry up to 68,000 gross tons of taconite pellets or 71,000 net tons of coal.
Her unloading system and 260-foot boom empty her five cargo holds in about eight hours.
Built by American Ship Building Company at Lorain, Ohio, in 1981, this vessel was first named William J. DeLancey. In 1990, she was renamed Paul R. Tregurtha in honor of Interlake's Vice Chairman of the Board.
The William J. De Lancey was rechristened Paul R. Tregurtha at Sturgeon Bay on May 23, 1990. The vessel was named in honor of Mr. Paul Richard Tregurtha; Vice Chairman of Interlake Steamship Co., and Chairman, C.E.O., and 50% owner of Mormac Marine Group, Inc. (owner of Interlake Steamship Co.).
The large self-unloading bulk carrier is powered by 2 Colt-Pielstick model 16PC2-3V-400 V-16 cylinder, four stroke, single acting diesel engines each rated at 8,560 b.h.p. built by Fairbanks Morse Engine Div., Colt Industries, Beloit, WI. Burning intermediate grade 280 fuel, power is directed through a Falk single reduction gear box to twin 17’06” (5.33m) diameter controllable pitch propellers giving the vessel a rated service speed of 15.5 m.p.h. She is equipped with a 1,500 h.p. bow thruster. Equipped with 36 hatches servicing 5 holds; the vessel is capable of carrying 68,000 long tons (69,092 mt) of iron ore at a mid-summer draft of 30’ 01” (9.17m) or a cubic capacity for 71,250 net tons of coal (equivalent of 63,616 long tons by comparison). Her Stephens-Adamson design loop belt elevator system feeds a stern mounted 260’ (79.25m) discharge boom that can be swung 100 degrees to port or starboard and is capable of unloading at a rate of 10,000 tons (10,161 mt) of ore per hour or 6,000 net tons of coal per hour. The self-unloader displaces 14,497 tons (14,730 mt) lightweight.
Coltec Industries Inc., Fairbanks Morse Engine Division has received an order valued in excess of $2.5 million for the first dual-fuel engine based on its technology sharing agreement with MAN B&W Diesel Inc.
The 12-cylinder FM/MAN 32/40DG engine will provide 6,192 brake horsepower to drive a four-megawatt electrical generating system for the city of Sabetha, Kansas.
The engine incorporates emission-reduction technology pioneered by Fairbanks Morse and MAN's advanced dual-fuel capabilities. Fairbanks Morse's Enviro-Design® technology reduces nitrogen oxide emissions to as low as one gram per brake horsepower hour, the lowest level recorded throughout the world by a dual-fuel engine. The dual-fuel engine is powered by natural gas and a pilot diesel fuel injection.
Warren Martin, president of Coltec's Fairbanks Morse Engine Division, said, "Our new partnership with MAN enables us to provide competitive products in the four- to six-megawatt range. This engine bridges the gap between our less-powerful opposed-piston power plants and our heavy-duty Colt-Pieslstick engines, which range up to 23,000 brake horsepower and drive much larger electrical generating systems."
Coltec Industries is a producer of landing gear systems and industrial sealing products as well as other highly engineered products for aerospace and other industrial applications. The Fairbanks Morse Engine Division, based in Beloit, Wisconsin, manufactures heavy-duty diesel, gas and dual-fuel engines for marine propulsion, the oil and gas industry, and for stationary and marine power generation.
