The bill aims to enhance access to solar energy for low-income individuals and renters by amending Chapter 25A of the General Laws. It establishes a new section that mandates the department to ensure equity and promote participation in the solar incentive program for low-income retail electric customers. This includes provisions for low-income multi-residential buildings to qualify as a single Low Income Customer, provided they meet specific criteria related to low or moderate income housing or receive federal low-income housing tax credits.

Additionally, the bill specifies that qualifying buildings will be treated as a single entity for the purposes of billing credits, incentive eligibility, and capacity allocations, regardless of the number of dwelling units or utility meters. This approach is designed to streamline the process for low-income households to benefit from solar energy incentives, thereby promoting greater participation in renewable energy programs.
