Bolstering Underutilized Industry by Leveraging Technology Transfer (BUILTT) for DOE

Solicitation # 06172026-Fritz

The Department of Energy, in partnership with the National Nuclear Security Administration, is launching the Bolstering Underutilized Industry by Leveraging Technology Transfer program to connect small and medium-sized U.S. businesses with low-volume, high-impact technologies developed at DOE and NNSA facilities. These technologies, often mission-critical and excluded from traditional commercialization pathways due to narrow market demand, will be made available through a new Cost Reduction License mechanism that enables qualified SMBs to manufacture and supply them directly to federal agencies at fair and reasonable pricing. The initiative, piloted through the Nevada National Security Sites, Y-12 National Security Complex, and Kansas City National Security Campus, aims to stimulate economic growth by empowering small manufacturers while ensuring continuity of critical government supply chains. Eligible participants must be U.S.-based businesses as defined by the Small Business Administration, with preference given to those located near the participating DOE/NNSA sites or holding designations such as SBA 8(a) or HUBZone. Interested firms will undergo a vetting process to confirm technical capability and alignment with available technologies, followed by tailored matchmaking with suitable opportunities. The program will be executed in phased stages including technology identification, SMB sourcing, licensing negotiation, and pilot implementation, with educational support provided to guide participants through licensing and production requirements. Regional economic development partners may also offer cost-sharing assistance. The pilot, funded by the DOE Office of Technology Commercialization and NNSA, is designed as a scalable model for broader government use, with submissions accepted through June 17, 2026, and responses due by April 1, 2027, via email to TPIP@nv.doe.gov. Participation does not guarantee award or compensation, and responses are strictly for informational purposes under the terms outlined.
