About this program

The Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy administers the Weatherization Assistance for Low-Income Persons program (CFDA 81.042) to improve home energy efficiency for low-income households, with the most recent grant award issued July 1, 2025.

The program funds whole-house energy retrofits including HVAC repair or replacement, insulation, air sealing, electric baseload measures such as lighting and refrigerator replacement, minor home repairs, and health and safety improvements. Eligible recipients prioritize elderly persons, those with disabilities, families with children, high residential energy users, and households with high energy burden. Weatherized homes achieve average annual energy cost savings exceeding $300 per household.

The portfolio consists predominantly of Formula Grants (644 awards, 84%) with smaller shares of Cooperative Agreements (63 awards, 8%) and Project Grants (60 awards, 8%). Across 767 total awards since 1981, DOE has obligated $18.69 billion in combined federal dollars, with non-federal cost-share contributions totaling an additional $470 million. DOE's main office accounts for 719 awards and $17.81 billion; the Office of Energy Efficiency and Renewable Energy holds 47 awards valued at $867.6 million; the Office of Fossil Energy holds 1 award worth $8.2 million.

Recent formula grant awards to states and territories range from $278 thousand (American Samoa) to $31.1 million (New York). Representative awards issued July 2025 include Maryland ($4.2 million for 280 planned units), Minnesota ($13.6 million for 412 planned units), and Pennsylvania ($21.9 million). Beyond formula distributions, Project Grants support workforce development and deep energy retrofits targeting justice40 communities and Native American communities, including awards to the National Association for State Community Services Programs and National Community Action Partnership for technical assistance implementing Bipartisan Infrastructure Law funding.

Solicitation DE-FOA-0002912, posted June 27, 2023 with a January 5, 2024 due date, offered $25 million in competitive grants (maximum $2 million per award) for WAP Enhancement & Innovation across three topic areas: multifamily housing, single-family and manufactured housing, and workforce development.

Objective and description

Objective

To improve home energy efficiency for low-income families through the most cost-effective measures possible. The program is funded by formula grants to states and administered at the state and local level.

Description

The U.S. Department of Energy's Weatherization Assistance Program (WAP) helps low-income households reduce their energy costs by improving home energy efficiency while ensuring health and safety.

Eligibility

Applicant eligibility

A State may also elect to make all homes eligible under the HHS Low-income Home Energy Assistance Program (LIHEAP) eligible for weatherization assistance and may use either 150 percent of poverty or 60 percent of State median income.

Uses of assistance

Improvement of the thermal efficiency and cooling of dwellings by the installation of weatherization materials such as attic insulation, caulking, weather-stripping, furnace efficiency modifications, certain mechanical measures to heating and cooling systems, and replacement furnaces, boilers, and air-conditioners.
