Public utilities: public service commission; certain provisions regarding rate cases and integrated resource plans; eliminate. Amends secs. 6a, 6m & 6t of 1939 PA 3 (MCL 460.6a et seq.); adds sec. 6x & repeals sec. 6aa of 1939 PA 3 (MCL 460.6aa).

Senate Bill 325 amends existing laws concerning how public utilities, including gas, electric, and steam providers, can adjust their rates for customers. It outlines the process for utilities to file rate increase requests with the Public Service Commission (PSC), requiring them to provide supporting evidence and allowing for public notice and hearings. The bill sets timelines for the PSC to review these applications and allows certain gas utilities to seek partial, immediate rate relief. A key change is the elimination of a provision that previously allowed utilities to implement proposed rate increases after 180 days if the PSC had not issued a final order, as this specific mechanism now only applies to applications filed before April 20, 2017.
