MN ~= 5000 MW
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

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.
The plant burns 30,000 tons of coal every day (three trainloads) and more
than nine million tons a year. A rotary car dumper, which literally turns
a rail coal car upside down, unloads one car every three minutes and an
entire train in just over six hours.

Ores, Primary NAICS: Iron Ore Mining Description: Mining: Manufacturing:
Iron ore and iron ore pellets.
Clay Boswell - 960 MW
Unit 4 Located in Bass Brook Township,
Minnesota * Coal-fired steam generating unit * WPPI Energy owns 20%
of Unit 4 * Plant operator/joint owner - Minnesota Power * Generating capacity
- WPPI share 107.5 MW (535 MW total) * Equipped with a scrubber and burns
low-sulphur Western coal * Commercial operation began January 1, 1980

The Boswell 3 Minnesota Power’s second-largest
coal-based facility. Boswell Unit 3, located in Cohasset, Minnesota, has
been in service since 1973 with a gross production of 375 megawatts (MW).
Riverside now gas fired. Xcel
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.

M/V
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. Source: Coltec Industries
