About Otter Tail Power Company
Getting to know us
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 (view our company history timeline to learn more). And our sustainability efforts tell the story of our ongoing commitment to environmental, community, and economic responsibility.
