About Open MPSC
A comprehensive, searchable archive of Michigan Public Service Commission documents, making regulatory information accessible to the public, researchers, and stakeholders.
Open MPSC was created to democratize access to Michigan Public Service Commission documents. We believe that regulatory transparency is essential for an informed citizenry and a well-functioning democracy.
Our mission is to provide free, easy-to-use access to thousands of regulatory documents including rate case filings, commission orders, Integrated Resource Plans, and meeting materials. By making these documents searchable and accessible, we empower citizens, researchers, journalists, and industry stakeholders to better understand the regulatory landscape.
