An Act relative to Mass Save assessments

This bill amends Massachusetts energy efficiency laws to require Mass Save program administrators to offer free "zero-carbon assessments" to all customers. These assessments identify non-combustible energy upgrades (like improved insulation, electric appliances, and solar) and include safety tests for existing gas systems. It mandates that utility companies collect and publicly share detailed energy use data by zip code, and establishes standards for contractors implementing these upgrades. The policy directly affects Massachusetts homeowners, businesses using Mass Save services, and utility companies managing energy efficiency programs.
