target of commencing operation by the end of 2027. This RFI seeks to 
assess industry interest in developing, operating, and maintaining AI 
infrastructure on select DOE owned or managed lands, along with 
information on potential development approaches, technology solutions, 
operational models, and economic considerations associated with 
establishing AI infrastructure on DOE sites. In addition, this RFI 
seeks input from grid operators that serve DOE sites on opportunities 
and challenges associated with existing energy infrastructure and 
potential co-location of data centers with new energy generation.
    DOE recognizes its relationships with Tribes and States and local 
governments as well as local communities, universities, businesses, 
utilities, and governments, contributing to economic development, 
education, and scientific advancement. As such, this RFI also seeks to 
gather input from potentially interested entities and individuals.
    For the purposes of this RFI, AI infrastructure includes AI data 
centers, which contain specialized Information Technology (IT) 
equipment and associated cooling facilities, as well as their energy 
supply, including sources of generation, such as nuclear energy, and 
transmission and storage.
    The Government anticipates authorizing land use rights and 
privileges through either a long-term Ground Lease or an Easement. The 
information gathered through this RFI may be considered in developing a 
public solicitation of private-sector proposals for AI infrastructure 
construction, operation, maintenance, and decommissioning on federal 
land.
    This RFI is issued solely for information and planning purposes and 
does not constitute a solicitation.

I. Background

    The U.S. Department of Energy (DOE) owns or manages significant 
amounts of land across the United States that may be suitable to 
support buildout of AI infrastructure. DOE sites offer potential 
advantages such as access to or the potential to build power 
infrastructure, secure locations, and opportunities for technological 
collaboration with DOE research facilities. DOE is considering 
opportunities to utilize these assets in a manner that enhances the 
United States' leading position in AI and benefits local economies. For 
the purposes of this RFI, the term ``AI infrastructure'' refers 
collectively to AI data centers, their specialized IT equipment and 
associated cooling facilities, and their energy supply, including 
sources of generation, transmission (including substations), and 
storage.
    For decades, DOE and its National Laboratories have been developing 
cutting-edge AI tools to support science, energy, and security 
missions. DOE and its National Laboratories are driving progress in AI 
through their enabling infrastructure: world-leading supercomputers, 
cutting-edge algorithms and software stacks through programs like the 
Exascale Computing Program, high-quality scientific datasets, and a 
scientific and technical workforce unmatched in the world to address 
the most critical energy, security, and science challenges of our time. 
DOE's capabilities and leadership in AI make it a natural partner for 
strategic public-private partnerships related to AI infrastructure.
    Additionally, DOE is a leader in developing advanced energy 
technologies. DOE and National Laboratory sites can provide an 
opportunity to accelerate deployment of key technologies like nuclear, 
geothermal, and energy storage, through existing site characterization 
work, existing energy infrastructure like microgrids and transmission 
availability, ability to support permitting, and supportive 
communities. For example, DOE has already performed extensive site 
characterization and permitting activities for new nuclear reactors at 
Idaho National Laboratory for the National Reactor Innovation Center.

II. Purpose

    The primary purpose of this RFI is to solicit information from 
entities with experience in the development, operation, and management 
of AI infrastructure. DOE is also seeking information from grid 
operators, technology developers, the public, and potentially affected 
entities on areas that should be considered or further evaluated for 
potential solicitations.
    DOE is seeking input on a range of topics, including:
    <bullet> Industry interest in any of the locations identified in 
the Appendices for consideration.
    <bullet> Potential data center designs, technologies, and 
operational models that could be deployed.
    <bullet> Potential power needs, timelines, and approaches to co-
locating energy sources with data centers or sources for surplus 
interconnection capacity.
    <bullet> Financial and contractual considerations related to 
leasing DOE owned or managed land for data center development.
    <bullet> Potential benefits and collaboration opportunities 
associated with siting AI infrastructure on DOE sites.
    <bullet> Economic, realty, and environmental information.
    <bullet> Potential challenges associated with siting AI 
infrastructure on DOE sites, and any additional information required 
for potential solicitations.
    DOE is interested in hearing Tribal government and community 
perspectives on potential collaboration with industry partners towards 
advancement of AI infrastructure goals. DOE has not made any final 
agency decisions at this time and will communicate with Tribes and 
stakeholders on potential proposed land uses, as appropriate.

III. Sites Under Consideration

    DOE has identified locations at 16 DOE owned or managed sites that 
could be amenable to hosting AI infrastructure. Publicly available 
information about each site, including location, available acreage, and 
other characteristics is provided in Appendices to this RFI. The 
potential DOE sites for AI infrastructure are listed below, in no 
particular order.

1. Idaho National Laboratory
2. Paducah Gaseous Diffusion Plant
3. Portsmouth Gaseous Diffusion Plant
4. Argonne National Laboratory
5. Brookhaven National Laboratory
6. Fermi National Accelerator Laboratory
7. National Energy Technology Laboratory
8. National Renewable Energy Laboratory
9. Oak Ridge National Laboratory
10. Pacific Northwest National Laboratory
11. Princeton Plasma Physics Laboratory
12. Los Alamos National Laboratory
13. Sandia National Laboratories
14. Savannah River Site
15. Pantex Plant
16. Kansas City National Security Campus

    Based in part on consideration of responses to this RFI, DOE will 
prioritize areas for potential future solicitations, gather additional 
site information to inform proposal development, identify potential use 
conflicts and mitigation measures, and develop terms and conditions to 
operate on DOE owned or managed lands. In potential future 
solicitations, DOE would aim to provide additional information such as 
acreage, access to water, environmental sensitivities, geotechnical and 
flood information, hazards, land use plans, power access and energy 
infrastructure, security, thermal management infrastructure, existing 
compute infrastructure, site access restrictions, and further 
information as determined from this RFI.
    The listed sites in this RFI are not comprehensive of sites under 
consideration by DOE. DOE has not made any preliminary or final 
decisions as to changes to land use or designation relating to those 
sites or others. This RFI is solely a request for voluntary information 
to inform future potential actions.

IV. DOE Realty Agreement Terms and Considerations

    DOE's statutory authority for leases and easements of DOE real 
property is outlined in Section 161g of the Atomic Energy Act of 1954, 
as amended (42 U.S.C. 2201g) and 40 U.S.C. 1304(b).
    DOE may enter into a realty agreement to lease land to an entity or 
enter into an agreement for an easement over the land, depending on the 
desired length and terms. Realty agreement terms could include 
requirements that non-federal parties agree to bear all responsibility 
for costs and liabilities related to construction and operation of the 
AI data centers as well as other infrastructure upgrades necessary to 
support those data centers, including costs to transmission providers 
or transmission organizations necessary to support the data centers. It 
is possible that in-kind contributions may be

[[Page 14974]]

counted as part of the costs of any non-federal party entering into a 
realty agreement. DOE anticipates that the AI infrastructure developer 
would be responsible for ensuring compliance with state and local 
requirements governing electricity, including interconnection 
requirements.
    A recent DOE initiative to locate energy generation on DOE lands 
includes examples of the range of terms that could be included in 
realty agreements for data centers. See <a href="https://www.energy.gov/management/osp/cleanup-clean-energy-expanding-clean-energy-generation-doe-lands">https://www.energy.gov/management/osp/cleanup-clean-energy-expanding-clean-energy-generation-doe-lands</a>.

Appendix 1. Idaho National Laboratory

    Summary: As the birthplace of nuclear energy and our nation's 
nuclear energy research laboratory, Idaho National Laboratory (INL) 
is well positioned to support efforts to attain AI dominance. INL 
has a legacy of building and testing advanced technologies, 
including 52 nuclear reactors with four currently in operation, and 
is also a leader in integrated energy systems and national and 
homeland security. The 890-square mile site, located in a region 
that is highly supportive of nuclear energy and INL's other 
demonstrations, offers ample opportunity for development and scaling 
to meet growing needs. Idaho regulatory and tax structures also are 
favorable towards ambitious projects that seek to advance U.S. 
global leadership.
    Site Details: Within the 890-square mile site, the U.S. 
Department of Energy (DOE) owns approximately 62,000 acres of land, 
as delineated on the map below. Remaining areas are public lands 
withdrawn to support Laboratory activities. The map below is a 
representation of select areas that have mixed levels of known 
characterization across the INL Site. Through comprehensive site and 
land use planning efforts, final areas will be determined based on 
identified need. Representing larger parcels of available lands 
allows for flexibility within those areas based on project scope and 
changing requirements. Federal lands adjacent to INL, which are not 
addressed in detail herein, also could be explored for projects and/
or project expansion. DOE Idaho Operations Office also maintains a 
close relationship with the Bureau of Land Management (BLM) and 
other Federal and state agencies.

Appendix 4. Argonne National Laboratory

    Summary: Argonne National Laboratory (Argonne) could accommodate 
a 110-acre developable site for a future 1,000 MW AI data park on 
U.S. Department of Energy (DOE) land with an early target for 
operations by 2028. Located 23 miles from Chicago, the region has 
the 6th largest U.S. workforce in AI-related occupations (over 
401,000 jobs) spanning tech, product, and commercial roles. 
Illinois' data center tax exemption and central location has pushed 
Chicago to #4 largest data center market in the U.S. by capacity. 
Chicago's relatively low power costs (6.5-6.7 cents/kWh average for 
large users); and low natural disaster risk are natural advantages 
for large scale, frontier AI datacenter siting. Illinois is a 
nuclear energy leader and is home to six operating nuclear plants 
with ~11.5 GW total generating capacity--more than any other U.S. 
state.
    Site Details: Argonne's total land area is 1,518 acres, which 
includes the 110-acre potential development site for the data park. 
The site is a combination of undeveloped and previously developed 
land. The property is solely owned by DOE. Adjacent area land 
ownership: Forest Preserve District of DuPage County; unincorporated 
areas of DuPage County, IL; residential and commercial use.
    The proposed data center site sits on the I-55 corridor, a major 
route southwest of Chicago that carries multiple long-haul fiber 
optic cables with ultra-low latency connections. Less than one mile 
is an existing ComEd (local utility) right of way with 345-kV 
double-circuit high-voltage electrical power, and adjacent to the 
site are substantial water resources, including the Chicago Sanitary 
& Ship Canal (CSSC) and the Des Plaines River flow. 60% of Argonne's 
electricity is comprised of nuclear power, with two large nuclear 
stations within 50 miles of Argonne.

York City. The BNL site is a Federal Enclave, fully owned and 
operated by Department of Energy (DOE). The site is managed by 
Brookhaven Science Associates (BSA). The proposed 90+-acre site for 
the data center is located within the BNL Discovery Park District, 
an innovative public-private partnership concept. The mission of 
Discovery Park is to promote federal and private development to 
enable mission enhancing technology transfer opportunities.
    Site Details: The properties surrounding the BNL site are mostly 
wooded and undeveloped. Ownership is private and predominately zoned 
for residential use with the exception of the south border. This 
area is predominately light industrial use. The total developable 
area of the preferred location is approximately 90 acres. This area 
is expandable however, and there are several similar sized 
undeveloped areas on the BNL site that could also be considered.

Appendix 8. National Renewable Energy Laboratory

    Summary: The National Renewable Energy Laboratory (NREL)'s 
Flatiron Campus has enough land, power, water, and broadband 
capability to host a 100 MW data center that could be initiated as 
soon as this year (2025). The site could support an integrated data 
center energy system test bed, that could be deployed later at scale 
at other locations. NREL's world-class expertise in scientific 
computing and partnerships with industry changing data center 
industry leaders would support the expeditious implementation of a 
data center at Flatirons. Through this project, NREL could help the 
U.S. establish global AI dominance and accelerate the transformation 
of the U.S. data center industry by dramatically reducing 
construction timelines, enabling the U.S. to rapidly deploy critical 
AI infrastructure at scale. NREL aims to establish a site where a 
developer can continue its usual business operations while using the 
site as a proving ground. The approach would not only allow the 
developer to focus on its business objectives but also provide 
national stakeholders with valuable insights into accelerating AI 
data center construction and power deployment, paving the way for 
future industry innovations.

[[Page 14987]]

Appendix 9. Oak Ridge National Laboratory

    Summary: The Department of Energy (DOE) has federal land 
available contiguous to the Oak Ridge National Laboratory (ORNL) 
which is well-suited to support the President's AI Infrastructure 
initiative within the two-to-three-year goal. The area has utilities 
anticipated to be sufficient to support the rapid development of an 
AI data center. Local power resources include 500KV transmission 
lines from local TVA hydro, nuclear, and fossil fuel generation 
plants. Additional onsite generation capacity is possible from a 
nearby regional natural gas distribution pipeline. The site is also 
located approximately 5 miles from the proposed TVA Clinch River 
Small Modular Reactor (SMR) site, providing a future opportunity to 
capitalize on regional nuclear infrastructure up to 800MW in 
capacity. Water resources are readily available from local utility 
providers or potentially developable on site from the Clinch River. 
Multiple commercial telecom providers are accessible from the site.
    Site Details: The site is a 562-acre plot of DOE land for 
potential commercial development with approximately 100-acres suited 
for near-term development that is centrally located near several 
major cities, natural waterways, and the interstate network. 
Adjacency to Oak Ridge National Laboratory (ORNL) provides strong 
synergy with existing world-leading research programs and user 
facilities for AI, high performance computing, and quantum 
information sciences. The proposed site has no significant 
environmental restrictions for development and poses no national 
security concerns.

Appendix 10. Pacific Northwest National Laboratory

    Summary: The Pacific Northwest National Laboratory (PNNL) in 
Richland, WA. PNNL has access to the highly skilled labor needed to 
construct and operate the power generation facilities; and to 
quickly build the proposed frontier AI data center, benefiting from 
construction costs that are significantly lower than the national 
average. The area offers a stable, dry climate with low humidity and 
minimal natural disaster risk, making it ideal for reliable 
operations. In addition to hydroelectric and conventional nuclear 
power, small modular reactors (SMRs) envisioned by energy providers 
in the region could provide additional power for the data center. 
These are among the reasons that major hyper-scalers have chosen 
eastern Washington for their large data centers.
    Site Details: The City of Richland currently owns 295 acres of 
available land (notated in the black outline below), transferred 
from the U.S. Department of Energy in 2015 under the condition of 
using it for economic development.

Appendix 11. Princeton Plasma Physics Laboratory

    Summary: Princeton Plasma Physics Laboratory (PPPL) and 
Princeton University (PU) explore the opportunity to have been at 
the cutting edge of high-performance computing and AI developments 
for decades, from Alan Turing's Ph.D. in the 1930s to John 
Hopfield's 2024 Nobel Prize in Physics for neural networks to Egemen 
Kolemen's Nature paper in 2024 using AI for fusion reactor control. 
The intellectual breadth of AI work in the Princeton ecosystem, 
including the recent announcement of an AI Hub for NJ centered here, 
combined with the available land and power infrastructure, make PPPL 
and PU ideal partners to host an AI data center and foster 
innovations that will advance computational science and scientific 
discovery. This center would emphasize accelerating fusion energy 
development and energy system optimization, exploit new data that 
will come from the NSTX-U fusion user facility that will come online 
in 2026, and foster public-private fusion partnerships. By aligning 
with the Department of Energy's broader AI development objectives, 
this center would drive advancements in AI tool development and 
implementation, support regional economic growth, and deliver on the 
vision of enabling next-generation computing capabilities through 
shared synergy, strength, and leadership.
    Site Details: PPPL is located in central New Jersey, occupying 
~88 acres on PU's Forrestal Campus. Forrestal Campus, located 
approximately three miles north of the University's main campus, 
encompasses 825 acres and hosts a blend of commercial leases, open 
space, and laboratory sites (DOE's PPPL and the National Oceanic and 
Atmospheric Administration's (NOAA's) Geophysical Fluid Dynamics 
Laboratory (GFDL)). Forrestal Campus offers a vibrant, cross-cutting 
ecosystem primed for test-bed development opportunities in AI. 
Public Service Electric & Gas Co. (PSE&G) is our site's local energy 
provider, NJ's oldest and largest gas and electric delivery public 
utility and one of the nation's largest. Our site currently has 100 
MW of energy capacity with district upgrade potential available, and 
current water contract with NJ Water Supply Authority includes ~55 
million gallons/year. The physical location in central New Jersey 
provides proximity to metropolitan areas and a multitude of 
commercial entities, providing ease of access for data center 
workforce and user recruitment. The PPPL-PU-hosted AI data center 
would also support an eastern hub of AI innovation serving public 
and private partners in (for example) Pennsylvania, New York, 
Connecticut, and Massachusetts.

Appendix 12. Los Alamos National Laboratory

    Los Alamos National Laboratory (LANL) is committed to an 
enduring on-premises High Performance Computing (HPC) and 
infrastructure to support its current plan-of-record and expanded AI 
mission scope. LANL has already responded to other recent calls for 
on/offsite data centers and has a consistent strategic approach that 
enables mission plan-of-record for continuing support for leading-
edge HPC and the expanded AI mission requiring up to 70MW by 2027 
and 160MW by the early 2030s. LANL is executing an upgrade of the 
Strategic Computing Complex (SCC) to 70MW, which requires the 
Electrical Power Capacity Upgrade (EPCU) and the SCC Electrical 
Upgrade (SEU) GPP; these projects are funded and near start of 
construction currently. LANL's strategy is to leverage new off-
premises power and water capabilities to supplement its enduring on-
premises capabilities. In responding to this call, LANL recognizes 
that this new on-premises commercial data center would expand our 
mission further, and without new power sources or exercising EPCU 
options, would be limited to a total of 100MW for HPC+AI 
infrastructure. This on-premises 100MW limit, would need to be 
operationally managed with the newly upgraded SCC (70MW) mission.
    The SCC could host low-density data systems, reducing its peak 
power needs to below current levels, and still take advantage of 
70MW total capability by re-configuring its electrical distribution 
back to its original configuration of 2N power. This would enable 
shifting power from the SCC to the new AI facility. A better 
approach would be to identify and deploy new on-premises power 
sources such as gas turbine (exercise options to expand the existing 
steam plant), or nuclear small modular reactors.
    Site Details: Identified, reserved, and generally undeveloped 
~40-acre land site adjacent to TA-06 WTA power substation for siting 
a high-density High Performance Computing facility suitable for AI 
(N-06-07 and N-06-06 on map below and in LANL site master plans). 
Site and surrounding land are DOE federally owned. Updated SWEIS 
nearing approval that includes new construction for a mission 
expanding new HPC infrastructure of at least 100,000 square foot 
facility, a 25,000 square foot staging facility, and a parking lot 
in currently undeveloped area in TA-06 adjacent to the WTA 
substation to support AI supercomputers to replace or supplement the 
current HPC at the SCC. The facility would use evaporative cooling 
and could require up to 162 million gallons of cooling water from 
Los Alamos County, and 62 million gallons of potable water would be 
required. An additional water treatment facility may be required to 
supply treated water for supercomputer cooling operations at the new 
facility. A new NPDES-permitted outfall was proposed in Two-Mile 
Canyon for this proposed facility. The facility was described as 
needing electrical demand of up to 100MW. This power would need to 
be coordinated with future use of the existing SCC. Expanded mission 
alternative also includes planning for up to 150MW of solar arrays 
on-premises.

Appendix 13. Sandia National Laboratories

    Summary: The National Nuclear Security Administration (NNSA)'s 
Sandia National Laboratories (Sandia) is responsible for the 
development, testing, and production of specialized nonnuclear 
components and quality assurance and systems engineering for all 
U.S. nuclear weapons. Sandia has locations in Albuquerque, New 
Mexico; Livermore, California; Kauai, Hawaii; and Tonopah, Nevada. 
It is managed and operated by National Technology and Engineering 
Solutions of Sandia, LLC.
    Site Details: Sandia has currently identified two sites of 
roughly ~9 acres each. There may also be a possibility to 
collaborate with Kirtland Airforce Base (KAFB) for a site. Tech Area 
II Site: This area is in a secondary conservation area. A biological 
survey would be required before the initiation of any outdoor work 
during the breeding season (March 1 through September 15). An 
archaeological survey would also be required prior to any ground 
disturbance. Eubank site: The proposed site would require an 
archaeological survey prior to any construction work. The site is 
not in a conservation area. Sandia is unique in that it is located 
on an Air Force Base which provides added security for a data center 
and infrastructure.

[GRAPHIC] [TIFF OMITTED] TN07AP25.020

Appendix 14. Savannah River Site

    Summary: The National Nuclear Security Administration (NNSA) 
operates a 310-square-mile site at the Savannah River Site (SRS) 
near Aiken, South Carolina, to supply and process tritium, a 
radioactive form of hydrogen that is a key component of nuclear 
weapons. SRS loads tritium and non-tritium reservoirs; processes 
reservoirs; and recycles, extracts, and enriches tritium gas. SRS 
also plays a key role in NNSA's nonproliferation missions. SRS is 
run by Savannah River Nuclear Solutions.
    Site Details: The footprint of a data center is very small 
compared to the 310 square miles of SRS; therefore, a more detailed 
description of the site requirements is required to select the best 
locations. Savannah River Site requires submission of a Site Use 
Permit application prior to allowing any activity on any tract of 
land onsite. The process provides: a method of informing various 
stakeholders of proposed

[[Page 14995]]

plans for a tract of land to identify conflicts between the permit 
application and previously granted permits; a forum for impacted 
stakeholders to communicate concerns about or support for the 
application; and a way to facilitate discussion between requestors 
and impacted stakeholders to establish guidelines and/or 
restrictions that allow the proposed usage to go forward.
    Once a suitable location for a data center is determined, the 
Site Use Permit application will be submitted. Approved permits may 
for example require or allow moving a boundary, relocating 
endangered species, providing access to monitoring stations, 
establishing buffer zones around wetlands, etc.

Appendix 15: Pantex Plant

    Summary: Constructed in 1942 as an ordnance facility, the Pantex 
Plant (Pantex) produced conventional artillery shells and bombs in 
support of the World War II effort. In 1951, Pantex was selected for 
use as a high explosives fabrication and weapon assembly 
installation for the nuclear weapon complex. Pantex is the nation's 
primary site for assembly and disassembly of nuclear weapons and is 
the Center of Excellence for High Explosives Manufacturing. Pantex 
also supports other priority objectives including nuclear component 
staging and storage and special nuclear material requalification, 
surveillance, and packaging.
    Site Details: Area 1 (PREFERRED): approximately 380 acres of the 
National Nuclear Security Administration (NNSA) owned land. There 
are water reservoirs, sprinklers and environmental wells in the area 
that would have to be considered for siting, but this is the 
preferred location. Area 2: approximately 5,700 acres currently 
owned by Texas Tech University (TTU) and leased by NNSA. This area 
could potentially be purchased from TTU but would require a real 
estate agreement. The southwest portion of Area 2 includes Formerly 
Used Defense Site land with historical contamination. Any of the 
farmland located around Pantex could be considered for purchase.
