Public utilities: rates; return on equity rates; limit. Amends sec. 6a of 1939 PA 3 (MCL 460.6a).

HB 6095 amends state law to regulate how public utilities in Michigan can raise their rates and charges. The bill requires utilities to obtain approval from the Public Service Commission before increasing costs for customers and mandates that they provide notice and hold hearings for affected parties. It establishes specific timelines for the commission to review rate applications and grants utilities the ability to implement proposed rate increases temporarily if the commission does not act within 180 days, provided they refund any excess amounts later with interest. Additionally, the legislation sets rules for spacing out rate filings by large electric utilities and outlines procedures for seeking immediate partial rate relief for smaller gas utilities.
