Budget request

The Budget requests $53.9 billion in discretionary budget authority for DOE, a $4.8 billion or nearly 10-percent increase from the 2026 enacted level excluding the Working Families Tax Cut Act (WFTC) funding. Within the requested amount, $32.8 billion is allocated to the National Nuclear Security Administration (NNSA), a $3.6 billion or 12-percent increase from the 2026 enacted level (including WFTC funding). The remaining $21.1 billion refects a $2.7 billion or 11-percent reduction from the 2026 enacted level.

IIJA funds redirected to $3.5 billion to “deploy firm baseload power” and $1.2 billion for AI to support seven AI supercomputers at the Argonne and Oak Ridge National Laboratories.

The Budget reproposes the cancellation of $15.2 billion in IIJA funding.

DOE abolished the EERE office in 2026.

Office of Science (–$1.1 billion): The Budget eliminates funding for climate change research.

Advanced Research Project Agency-Energy (ARPA-E) (–$150 million).

The Budget prohibits the use of Federal funds for expensive subscriptions to academic journals unless required by Federal statute or approved in advance by a Federal agency
