Senate Bill No. 422 aims to amend the classification of biomass facilities within Connecticut's renewable energy framework. Specifically, it removes the exception that allowed biomass facilities with agreements to provide energy to electric distribution companies (EDCs) before October 1, 2025, to be considered Class I renewable energy sources. The bill repeals the previous definition of Class I renewable energy sources, which included biomass facilities that used sustainable biomass fuel and met certain emission standards or capacity limits. By eliminating this exception, the bill effectively disqualifies these biomass facilities from receiving benefits associated with Class I status, such as participation in power procurements and the ability to sell renewable energy credits.

Additionally, the bill modifies the definitions related to biomass power purchase agreements, removing references to environmental attributes and capacity from the products that EDCs may purchase through solicitations by the Department of Energy and Environmental Protection (DEEP). The changes are set to take effect on October 1, 2026, and are intended to align the state's renewable energy policies with its solid waste management plan while also addressing emissions standards. Overall, the bill reflects a shift in policy regarding the role of biomass in Connecticut's renewable energy landscape.
