MI HB4283

Establishes renewable energy credit portfolio requirements for electric providers: 15% through 2029, 50% from 2030-2034, and 60% from 2035 onward

Allows cooperative and multistate electric providers to reduce their renewable energy requirements by subtracting megawatt hours of nuclear energy obtained from Michigan-based systems owned or contracted before January 1, 2024

Permits electric providers operating coal replacement engines (RICE generators) to file a simplified certification instead of standard compliance filings, provided they maintain at least a 15% renewable energy credit portfolio

Authorizes the commission to grant 2-year extensions on renewable energy deadlines for good cause, including transmission interconnection delays, labor shortages, excessive customer costs, or grid reliability concerns

Requires electric providers using the coal replacement engine exemption to still file integrated resource plans showing how they will comply with full renewable and clean energy standards by the end of the 2050 MISO planning year
