Otter Tail Power Company

We're an investor-owned electric utility that provides electricity for residential, commercial, and industrial customers in Minnesota, North Dakota, and South Dakota.

Our company is named after the Otter Tail River, which provided our first source of electricity when we became an operating utility in 1909. Hundreds of years ago the Ojibwe noted that a large sandspit follows the contour of the shoreline of a lake where the river flows into it. Because they thought this sandspit resembled the tail of an otter, the Native Americans named the lake Nigagwanoe, Otter Tail. By doing so, they also named a river, a village, a township, a county, and a power company.
