An Act limiting the eligibility of woody biomass as an alternative energy supply

This bill restricts woody biomass from being counted as an alternative energy source for new or large-scale power plants in Massachusetts. It specifically targets intermediate and large generation units, prohibiting them from using wood-based fuel to meet renewable energy requirements. However, the law includes a grandfather clause that protects existing facilities already certified as alternative energy units as of January 1, 2023. The changes take effect immediately upon the bill's passage, altering how future energy projects are classified and regulated.
