About this agency
The Department of Energy, a civilian cabinet department, procures and funds energy research, development, and infrastructure work across the federal government's national laboratories, universities, and commercial entities. The Department transacts through both contracts and grants, with a substantial portfolio spanning nuclear energy, renewable resources, energy efficiency, grid modernization, scientific research, and departmental operations.
The Department awarded 85,650 federal contracts since 1973, with combined potential value of $1.186 trillion and $888.17 billion obligated to date. Contract volume has declined recently: 2,121 awards in 2022, 2,543 in 2023, 2,161 in 2024, 1,515 in 2025, and 804 year-to-date in 2026. The most recent award date is recorded as October 16, 2026. Among active primes over the last five years, competitive concentration is highly fragmented by award count—the top five hold only 9 percent of recent awards—but Accenture Federal Services LLC leads by potential value with $2.47 billion across 78 awards. Energy Technology Alliance LLC, Thundercat Technology LLC, and Carahsoft Technology Corp follow, each with $244 million to $348.9 million in reported value. Other high-volume primes such as Satcom Direct Government, LLC (294 awards) and The Building People LLC (173 awards) transact primarily through vehicles with limited dollar transparency. The Department reserves roughly three-quarters of contracts for unrestricted competition; small-business set-asides account for 19 percent of awards, with 8(a) sole-source awards comprising 4 percent of the portfolio.
The Department obligated $154.49 billion in federal grant dollars across 54,496 awards since 1976, with combined federal and non-federal funding totaling $221.45 billion. Grant-making cadence shows 2,308 awards in 2023, 2,538 in 2024, 1,586 in 2025, 281 in 2026, and one award recorded in 2028. University recipients dominate: University of Wisconsin System, MIT, University of Michigan, and University of Illinois each hold between 95 and 107 awards over the last five years. By federal dollars obligated, Michigan State University leads with $508.3 million across 64 awards; the top five recipients capture only 1 percent of recent federal dollars, indicating highly fragmented recipient concentration. Project Grants represent 64 percent of the assistance mix, Cooperative Agreements 27 percent, Formula Grants 6 percent, and Block Grants 3 percent.
Current contract opportunities span equipment procurement (magnetic measurement systems, vacuum pumps, laser ablation systems, microscopes, purification systems), maintenance services (FLACS support, Commvault renewals), and technology partnerships—notably Argonne National Laboratory's multiple RFIs (due August 21) seeking industry input on AI supercomputing infrastructure, equipment, and public-private co-funding models for a National Genesis Mission Supercomputing Center. Hydropower Testing Network voucher opportunities for small businesses (due July 23) offer no-cost INL technical assistance. Chain Reaction Innovations solicitation (due October 30) supports energy technology innovation.
Grant opportunities include ARPA-E's High-performance Optimized Recycled Nuclear Isotopes program (HORNIG, due August 6), focused on transformational nuclear research; Improved Oil and Gas Recovery and Produced Water Management Technologies (due September 8, with Modification 000002 adjusting cost-share requirements and application content), offering Cooperative Agreements for unconventional reservoir recovery and water treatment; and forthcoming CMEI/AFFO Accelerating Scale-up and Pre-piloting of Emerging Chemical Technologies (ASPECT, due September 14), supporting scale-up of novel chemicals from alternative feedstocks.
