Otter Tail Power Company, a subsidiary of Otter Tail Corporation, has submitted a request to the South Dakota Public Utilities Commission to increase its electric rates. The proposal seeks to address rising costs associated with maintaining a safe and reliable energy system while accommodating growing electricity demand. The request, if approved in full, would result in a rate increase of approximately $5.7 million, translating to an average net increase of about 12.5% for customers. The company emphasizes its commitment to providing cost-effective energy solutions and highlights efforts to manage costs through strategic investments and operational efficiency. The PUC will review the request, and should it not make a decision within 180 days, Otter Tail Power may implement interim rates starting December 1, 2025. Customers will be refunded if final rates are set lower than the interim rates. Information on rate changes and updates will be accessible on the company's website.
