Otter Tail Power will invest $10 million to comply with a mercury-control deadline, allowing the two-unit Hoot Lake plant to burn coal until 2020. The utility must now propose how to replace the coal generators. The options include new natural gas generators, renewable energy, or more conservation.
The generators, which went into service in 1958 and 1964, supply about 20 percent of the electricity for Otter Tail’s 129,000 customers in western Minnesota, North Dakota, and South Dakota.
On Oct. 27, 1986, the Otter Tail Valley Railroad commenced service over 151 miles of track between Avon and Moorhead, Minn., plus short branches out of Fergus Falls, the line’s headquarters. Ninety percent of the railroad’s business was between Moorhead and Fergus Falls, and in 1991 the railroad abandoned the 96 miles of railroad east of Fergus Falls. Owned by Genesee & Wyoming, OTVR interchanges with BNSF Railway at Dilworth. In addition to coal, the railroad handles ethanol, corn, grain, and soybeans.
