The bill amends the 1939 Public Utilities Act to strengthen the regulation of public and private utilities in Michigan, particularly concerning rate increases and the approval process. It requires utilities to obtain commission approval before raising rates or altering rate schedules, mandates coordination with commission staff prior to filing rate cases, and establishes a timeline for the commission to assess application completeness. The bill abolishes automatic adjustment clauses and prohibits rate increases based on fuel cost changes without proper notice and hearings. It also introduces provisions for revenue decoupling for smaller utilities and ensures that if the commission does not issue a final decision on a rate case within a specified timeframe, the application is automatically approved.

Additionally, the bill establishes the Utility Consumer Participation Board to oversee the Utility Consumer Representation Fund, which supports residential utility consumers. It outlines the board's operational procedures, including public meeting requirements and financial contributions from energy utilities. The bill also introduces new requirements for the commission to conduct assessments related to energy waste reduction and demand response programs, mandates a structured timeline for reviewing integrated resource plans (IRPs), and allows utilities to request adjustments to filing dates. It emphasizes the need for diversity in generation supply and introduces criteria for evaluating the reasonableness of energy measures and costs. Overall, the amendments aim to enhance transparency, accountability, and consumer protection in utility regulation.
