Boulder City Tests Federal Data Center Approval
Coverage from Nevada Public Radio, KUNR, and others
The Townsite Data Center near Boulder City, Nevada, became a test of how federal agencies approve data centers on public land after BLM amended an earlier solar-project authorization for an 81-acre site.
Boulder City, environmental groups, and residents challenged the decision over local coordination, public participation, water use, and whether the existing environmental review was adequate. The Interior Board of Land Appeals later halted the approval, leaving the project’s planned 2027 construction and 2028 operations uncertain.
If you read one thing
It provides the clearest broad overview of the Townsite approval, Boulder City's challenge, and the underlying federal-local conflict.
Latest development
It captures the decisive appeals-board stay and explains why project-specific NEPA review is now the central constraint.
The counter-case
It presents the opposing position that BLM could rely on the existing solar review and amended federal authorization.
The evidence
It adds concrete evidence about cooling-water needs and the environmental differences between the data center and the solar project.
Project-specific environmental review is now the central legal constraint
The Interior appeals board stayed BLM's approval after finding that the agency likely could not rely on the solar project's review for the materially different data center. Construction is paused while expedited proceedings and a broader environmental review move forward, although the stay is not a final rejection.
Federal siting authority remains in conflict with local land-use control
Boulder City continues to argue that converting the solar-and-storage proposal into a data center required renewed local coordination and review, while BLM's federal-land approval bypassed the city's ordinary process. The stay has not resolved the underlying dispute over community authority.
Water, power, and operational impacts distinguish the data center from the solar project
Opponents identify materially greater demands than those assessed for the solar proposal, including estimated construction water use of 560 acre-feet versus 25 acre-feet and electricity needs potentially several times Boulder City's existing load. Cooling and final water arrangements remain contested despite the developer's air-cooling plans.
Townsite remains a precedent-setting test for federal data-center expansion
Townsite is testing whether federal agencies can accelerate data-center siting by modifying existing renewable-project approvals. The stay and likely requirement for project-specific review weaken the immediate replicability of that pathway while increasing the case's significance for other federal-land proposals.
300,000-square-foot square feet
proposed data center size
“He described the proposed 300,000-square-foot data center as a different project from the 19-MW solar facility.”
167-MW
planned data center capacity
“A federal appeals board halted approval Sept. 1 for the 167-MW Townsite Data Center on U.S. Bureau of Land Management property near Boulder City, Nev., finding that BLM likely violated the National Environmental Policy Act by relying on an environmental review prepared for a materially different, unbuilt solar project.”
19-MW
proposed solar facility capacity
“BLM approved the data center in June without preparing a new or revised environmental assessment. It instead relied on a 2023 review of a proposed 19-MW solar facility and battery storage system at the same site.”
12 months
estimated solar-project construction duration
“The board noted that the solar assessment estimated about 12 months of construction, while BLM estimated up to 18 months for the data center. Grouping both into a 12-to-18-month range, Gunter wrote, masked the potential for a 50% increase in construction impacts, including noise, dust, emissions and traffic.”

Contested Issue
Did BLM lawfully rely on the prior solar project's environmental review, or was a project-specific NEPA review required for the data center?
BLM determined that the data-center conversion was sufficiently similar to the previously reviewed solar project and approved it without a new assessment. Challengers and the Interior Board of Land Appeals characterized the data center as materially different, citing larger construction impacts and different water, pollution, habitat, and operating effects.
Existing review sufficient
The prior solar project's environmental review adequately covered the amended data-center use because BLM determined that the relevant impacts were not materially different.
Project-specific review required
The data center was not substantially the same as the solar project, so BLM likely violated NEPA by approving the conversion without a new, project-specific environmental review.
Could the data center proceed under the amended federal permit, or did the change from solar-and-storage use require a renewed local application and land-use review?
BLM authorized the data center by amending the existing federal solar-project authorization. Boulder City officials argued that replacing or adding the solar use with a data center materially changed the project and required a new application, renewed local review, and consideration of local land-use requirements.
Amended federal authorization
BLM could authorize the data center by amending the existing federal solar-project permit, allowing the project to proceed without restarting Boulder City's application process.
Renewed local review required
Adding a data center to the solar-and-battery proposal materially changed the project, requiring Townsite Solar 2 to restart its application and address local land-use requirements.
The new articles reinforce that the Townsite Data Center remains halted while the NEPA challenge proceeds, adding detail about the board’s finding that the solar review understated the data center’s construction impacts but not materially changing the Topic’s status.
Previously
The Townsite Data Center, proposed on an 81-acre federal parcel near Boulder City, Nevada, was approved by the Bureau of Land Management after the agency determined that an earlier solar-project environmental assessment was adequate. Boulder City, environmental groups, and residents challenged the decision over local coordination, public participation, water use, and the scope of National Environmental Policy Act review; an Interior Department appeals judge later halted development while the challenge proceeds. The case could shape how quickly similar data centers are approved on federal land, particularly in water-constrained Western communities.
The project is now more concretely characterized as a roughly $3 billion, 167-MW facility targeting construction in 2027 and operations in 2028, though the appeal has made that schedule uncertain.
The dispute escalated from an unresolved appeal into an active legal halt: an Interior appeals judge suspended development after finding a persuasive potential NEPA violation. New water-use figures also sharpen the controversy, while a separate Colorado Springs approval broadens the regional context.
