An Act relative to energy affordability, independence and innovation

H 4144 creates a new funding mechanism to support building decarbonization and energy efficiency programs across Massachusetts. It imposes a 2.5 mills per kilowatt-hour charge on electricity consumers (excluding municipal light plant users) and pools funds from cap-and-trade programs and other sources to finance these initiatives. The law requires 20% of these funds to target low-income residential buildings, with additional priority for moderate-income households, renters, and small businesses. Electric distribution companies and municipal energy groups must submit a statewide decarbonization plan every three years, detailing cost-effective programs to reduce fossil fuel use and energy costs while meeting greenhouse gas targets.
