The MPSC provides many different opportunities for the public to participate in cases, workgroups or events. Customers, business owners, consultants, etc. may share their views by becoming an intervenor in a case, attending and speaking at Commission meetings or public hearings, commenting on a case, writing a letter to the Commission or filing a complaint or inquiry with MPSC Staff.
The Commission conducts most of its official business through the formal case & hearing process. There are several types of cases related to the regulation of electric, natural gas and telecommunications services that come before the Commission.
Contested Case: A proceeding, including rate-making, price-fixing, and licensing, in which a determination of the legal rights, duties, or privileges of a named party is required by law to be made by an agency after an opportunity for an evidentiary hearing. MCL 24.203(3). All parties must be represented by licensed attorneys, except that individuals who are not licensed attorneys may represent themselves.
Ex Parte: A proceeding, initiated by one party, requesting relief that does not result in an increase in the rates, charges, or cost of service to customers. Ex parte relief may be authorized and approved without notice or hearing. The Commission will determine if the relief requested is in the public interest. The Commission may, in its discretion, direct a contested case proceeding.
Commission’s Own Motion: The Commission may initiate a proceeding to address important issues within its jurisdiction that do not arise from an individual party’s request. This type of proceeding is often an uncontested case.
Investigation: An investigation is initiated by the Commission on its own motion to review an issue that involves one or more utilities. An investigation may result in a contested case.
Show Cause: A proceeding, on the Commission’s own motion, that requires a party to explain why the Commission should not take a certain proposed action. If the party fails to give sufficient reasons why the Commission should take no action, the Commission will take action. This proceeding typically requires a party to show why it did not violate a particular rule or Commission’s order. A show cause proceeding is a contested case.
Complaint: The Commission conducts both informal and formal complaint proceedings. An informal complaint proceeding is usually held before MPSC Staff or other mediators and involves a good faith attempt of the parties to settle a dispute before a formal complaint is filed. A formal complaint is held before an administrative law judge and is a contested case.
Rulemaking: A statute may authorize or direct the Commission to promulgate rules or initiate changes to existing rules. Before adopting or changing a rule, the Commission must follow the procedures under the Administrative Procedures Act (MCL 24.231-24.266), which include providing notice of and conducting a public hearing regarding the proposed rule.
Adjudicatory proceeding: A proceeding before an administrative agency in which the rights and duties of particular parties are adjudicated or decided after notice and opportunity to be heard. A contested case is an adjudicatory proceeding. In contrast, the proceeding before a court is a judicial proceeding.

The Commission typically holds two meetings a month, although additional meetings may be added to the schedule as needed. All meetings are held at the Commission’s office located at 7109 W. Saginaw Hwy, Lansing, Michigan, unless otherwise noticed in advance. Any person present at a Commission meeting may address the Commission during the time reserved on the agenda for public comments. Public comments will be included in the live stream and recordings of the Commission meeting and may be posted on the MPSC’s website. The meeting site is handicap accessible and anyone requiring additional accommodations are encouraged to contact the MPSC’s Executive Secretary at (517) 284-8090.
The Commission will sometimes hold a public hearing in certain proceedings to allow customers of a utility and other interested people to share their comments on a pending case about their utility. The Commission typically schedules public hearings in the service territory of the utility. Prior to the hearing, the Commission will publish a public notice of hearing and will also provide information about the hearing to local organizations for distribution.
The MPSC has established workgroups with the purpose of investigating specific issues or developing and streamlining various regulatory activities. These workgroups can include participants from MPSC Staff, regulated utilities, industry experts, utility customers and others.
Tribal involvement guide
Executive Directive 2019-17 directed each department and autonomous agency to adopt and implement a process for consulting on a government-to-government basis with Michigan’s federally recognized tribes. The Commission’s Guide for Involvement by Tribal Governments in Infrastructure Siting Cases at the Michigan Public Service Commission (The Tribal Involvement Guide) explains the options available to the Tribes for participating in contested cases before the Commission.
