The bill pertains to the 2023 Annual Report on self-generation installations in Massachusetts, as mandated by Section 193 of the Electric Restructuring Act. The report evaluates the impact of self-generation technologies, such as cogeneration, fuel cells, and renewable energy systems, on electricity sales and transition cost recovery by electric distribution companies. The report highlights that there were 29,220 self-generation installations in 2023, predominantly solar systems, which resulted in an estimated reduction of 5.1 million megawatt-hours (MWh) in electricity sales, representing a 12.36 percent decrease in total sales. The cumulative reduction since the inception of self-generation reporting in 1998 is approximately 35.4 million MWh.

Despite the increase in self-generation installations, the report concludes that these installations have not significantly affected the transition cost recovery for electric distribution companies. The transition costs, primarily linked to legacy long-term power purchase agreements, have been largely recovered, with minimal impact from self-generation, generally less than 1.5 percent for each company. The report indicates that while the immediate effects of self-generation on electricity sales are relatively small, there is potential for a more substantial impact over time as self-generation continues to grow.
