S.D. Codified Laws § 49-34A-58
The Public Utilities Commission may, after a hearing had upon due notice, make such findings as may be supported by proof as to whether any electric utility operating in an assigned territory is rendering or proposes to render adequate service to a customer, and in the event the commission finds that such electric utility is not rendering or does not propose to render adequate service, the commission may enter an order specifying in what particular said electric utility has failed to render or to propose to render adequate service in order that such failure be corrected within a reasonable time, such time to be fixed in such order. If the electric utility so ordered to correct such failure fails to comply with such order, the commission may authorize another electric utility to furnish retail service to such customer.
