File a Complaint About Your Utility Service or Ask a Question

The Minnesota Public Utilities Commission's Consumer Affairs Office (CAO) helps resolve disputes between customers and utility companies. You can call the Consumer Affairs Office at 651.296.0406 or 800.657.3782 or email at consumer.puc@state.mn.us.

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.
