Additional funding from the Bipartisan Infrastructure Law (BIL) is also available to further expand the AFFECT grant program.

On December 2, 2022, the Federal Energy Management Program (FEMP) issued a Federal Agency Call (FAC) on EERE Exchange titled Assisting Federal Facilities with Energy Conservation Technologies (AFFECT) 2022 Appropriations. On August 23, 2023, FEMP announced the selection of the following 19 federal agency projects to receive a combined total of $28.1 million in AFFECT funding.

These grants will support various initiatives such as energy-efficiency measures, renewable energy installations, load management strategies, and resilience improvements. By implementing these projects, federal agencies aim to achieve their missions more efficiently and generate economic benefits by attracting private investment, creating jobs, and adopting American-made technologies. 

These efforts align with FEMP's commitment to the Biden Administration's energy reduction and sustainability goals, enabling the federal government to lead by example in energy efficiency and clean energy adoption. The selected projects are expected to:

  • Reduce the federal government's annual energy costs by $22.7 million
  • Reduce greenhouse gas emissions by 82,648 MTCO2e
  • Include $837 million in private financing.
