Energy Efficiency Rebate Programs

    • This section appropriates $4.3 billion to remain available through September 30, 2031, to carry out a program to award grants to state energy offices to develop and implement a HOMES rebate program.
      • The program shall provide rebates to homeowners and aggregators for whole-house energy saving retrofits completed before October 1, 2031. 
      • The total rebate amount varies depending on the type of property and the type of retrofit, with enhanced rebates for low- and moderate-income households.
      • This program is based on the HOPES for Home Act. The bill also includes contractor training provisions. The rebate program is intended to “create incentives for homeowners to invest in energy efficiency improvements.”
    • Funding Eligibility: Funds are to be distributed to state energy offices, which then distribute funds to individuals and aggregators to implement energy efficiency upgrades.
      • Funds do not need to be used to retrofit homes occupied by low- or moderate-income households, but the rebate amount is higher for these projects. State energy offices also have the discretion to increase the rebate amount for low- or moderate-income households.   
      • The legislation does not define the term “whole-house energy saving retrofits.”
        • The DOE mentions the Weatherization Assistance Program (WAP) as an example of a “whole house weatherization” approach that analyzes all of the building systems—the building envelope, heating and cooling systems, electrical system, and electric baseload appliances—through the completion of an energy audit.
        • The DOE mentions the “Energy Saver: Whole-House Systems Approach” on its website.
          • “This approach considers the house as an energy system with interdependent parts, each of which affects the performance of the entire system. It also takes the occupants, site, and local climate into consideration.”

                                                                                                                        

    • Funding Timeline: Funding is to remain available until expended through September 30, 2031. If all funding were expended before that date, additional funds would need to be appropriated by Congress.
    • State energy programs shall submit applications for the HOMES rebate program in accordance with certain requirements, including determinations of reductions in home energy use and monitoring implementation of the program.
    • This provision establishes a program to award grants to state energy offices and Indian Tribes to develop and implement a high-efficiency electric home rebate program.
      • For state energy offices, $4.275 billion is to remain available through September 30, 2031.
      • For Indian Tribes, $225 million is to remain available through September 30, 2031.
      • This program is based on legislation formerly known as the Zero-Emission Homes Act, which seeks to encourage the purchase and installation of electric appliances and equipment in single-family homes and multifamily buildings.
    • Funding Eligibility:
      • For this program, the federal government will appropriate money to local governing bodies, which will then distribute funds to one of the eligible entities listed below. 
      • $4.275 billion is appropriated to state energy offices, which are then to award funds to eligible entities for qualified electrification projects.
      • $225 million is appropriated to Indian Tribes, which are then to award funds to eligible entities for qualified electrification projects.
      • “Eligible entities” that can receive funding from state energy offices and Indian Tribes include:
        • A low- or moderate-income household.
        • An individual or entity that owns a multifamily building not less than 50 percent of the residents of which are low- or moderate-income households.
        • A governmental, commercial, or non-profit entity, as determined the Secretary of Energy, carrying out a qualified electrification project on behalf of one of the entities described above. These “qualified electrification projects” are listed below.
    • Funding Timeline: Funding is to remain available until expended through September 30, 2031. If all funding were expended before that date, additional funds would need to be appropriated by Congress.
    • Qualified Electrification Projects:
      • The amount of the rebate for appliances shall be:
      • The amount of the rebate for non-appliance upgrades shall be:
        • Not more than $4,000 for an electric load service center upgrade.
        • Not more than $1,600 for insulation, air sealing, and ventilation.
        • Not more than $2,500 for electric wiring.
      • Qualified electrification projects must be certified under the Energy Star program established by Section 324A of the Energy Policy and Conservation Act (42 U.S.C. 6294a), if applicable.
    • State energy offices and Indian Tribes are to submit grant applications for funding, outlining:
      • Plans to verify income eligibility of eligible entities seeking a rebate.
      • A plan to allow rebates for qualified electrification projects at the point of sale in a manner that ensures that the income eligibility of an eligible entity seeking a rebate may be verified at the point of sale.
      • A plan to ensure that an eligible entity does not receive a rebate for the same qualified electrification project through both a high-efficiency electric home rebate program and any other federal grant or rebate program.
    • The maximum rebate for an eligible entity is $14,000.
      • 100% rebates are available for individuals with an annual income less than 80% of the median income. Otherwise, rebates may only cover 50% of the cost of a qualified electrification project.
    • This provision provides $200 million to remain expended through September 30, 2031, to provide financial assistance to states to develop and implement programs to provide training and education to contractors involved in the installation of home energy efficiency and electrification improvements.
       
    • Funding Eligibility: For this program, the federal government will provide funding to states, which will then use that funding to implement the relevant training programs.  
       
    • Funding Timeline: Funding is to remain available until expended through September 30, 2031. If all funding were expended before that date, additional funds would need to be appropriated by Congress.

        • This provision appropriates $500 million to remain available until September 30, 2024, to carry out the Defense Production Act.
        • It is unclear how this funding will be distributed, but it is expected that the funds will be divided evenly between critical minerals and heat pumps.
