Filing a Complaint

A complaint is a statement that there is a problem with your utility service or customer service, or that the utility has done something wrong. A complaint could ask the Minnesota Public Utilities Commission (PUC) for help with a problem or just share information. You can make a complaint at any time about anything that the PUC regulates. Complaints may be shared with your utility provider and, if you agree, added to the official record if it is related to a case.
