This bill, titled the "Energy Savings and Weatherization Reauthorization Act of 2025," reauthorizes the federal Weatherization Assistance Program (WAP) through 2030 , extending its support for energy efficiency improvements in low-income homes. It significantly increases the maximum average cost per dwelling unit from $6,500 to $15,000 , enabling more comprehensive weatherization projects. The legislation also introduces a new definition for a " fully weatherized " dwelling unit, requiring complete installation of recommended measures and a final quality control inspection. Additionally, it raises the limit for specific health and safety measures to $6,000 and grants the Secretary of Energy flexibility to increase financial assistance limits based on market conditions. These changes aim to enhance the program's effectiveness and reach, ensuring more homes receive thorough and impactful energy upgrades.
