In October 2008, Michigan enacted the Clean, Renewable, and Efficient Energy Act (Public Act 295), requiring the state’s investor-owned utilities, alternative retail suppliers, electric cooperatives, and municipal electric utilities to generate 10% of their retail electricity sales from renewable energy resources by 2015. SB 438, signed in December 2016, increased this requirement to 15% by 2021, and made other changes. The standard allows utilities to use energy waste reduction (i.e., energy efficiency) to meet a limited portion of the requirement.
Under the standard, eligible renewable energy include biomass, solar photovoltaics (PV) and solar thermal, wind, geothermal, municipal solid waste (MSW),* landfill gas, existing hydroelectric, tidal, wave, and water current (e.g., run of river hydroelectric) resources.
Biomass is broadly defined as organic matter that is not derived from fossil fuels and which replenishes over a human time frame. New hydroelectric facilities that require new dam construction are not considered an eligible resource, although repairs, replacements, and upgrades of existing dams may be counted towards compliance.
