Open MPSC is an unofficial, volunteer-operated archive that helps people explore public records from the Michigan Public Service Commission. It is an independent project and is not affiliated with, endorsed by, or connected to the Commission or the State of Michigan. The archive brings together searchable information on regulatory cases and proceedings, filings, testimony, applications, briefs, commission orders, decisions, parties, public comments, interventions, hearings, and meeting agendas and documents.

Visitors can search by topic, company, case number, or keyword, or browse dedicated sections for cases, meetings, filings, orders, and parties. Search tools include full-text indexing, AI-powered classification, and advanced filtering. The site also offers analytics and an overview of archive information, helping users navigate records involving Michigan’s electric, natural gas, and telecommunications utilities. Example search topics include solar energy, data centers, geothermal, 5G, electric vehicle charging, wetlands, and water rights. Open MPSC is presented as a public service; users seeking official records or information are directed to the Michigan Public Service Commission’s official website.
