The U.S. government has placed a broad hold on onshore wind development, stopping progress on an estimated 165 projects located on private lands as part of a national security review, according to industry sources and people close to the matter.
The Pentagon is reportedly withholding approvals while it reassesses procedures used to judge the national security impacts of energy infrastructure. Letters delivered to developers in early April indicated the department was reviewing how it evaluates the effects of proposed energy projects on national security.
Developers and industry representatives say the pause has been sudden and disruptive. Since August 2025, companies pursuing onshore wind projects have encountered a marked lack of expected communication from the Pentagon: meetings have been canceled without being rescheduled, applications have been told to no longer expect processing, and routine exchanges have gone unanswered, according to people familiar with the situation.
The projects affected span a range of development stages. Some are awaiting final sign-off, others are in the midst of negotiation, and a subset are projects that historically would not have required Pentagon oversight. The American Clean Power Association and individuals close to the matter provided the estimate of about 165 projects on private land that are currently on hold.
The pause has already prompted legal challenges. Lawsuits have been filed contesting the halts, which are being justified publicly by classified national security concerns, specifically potential interference with radar systems. Developers have long faced delays while engaging federal authorities, and those delays have continued under the current administration, which has voiced criticism of wind turbines as an energy source.
Statements from the administration and defense officials cited in developer communications reference concerns about radar interference, but the classification of the material underlying the decisions has limited what can be publicly disclosed. That classified status is also a central element in litigation and in developer complaints about the lack of transparency in the review process.
The immediate effect is a deepening uncertainty for onshore wind projects on private land, with applications stalled, meetings canceled and no clear timeline for the resumption of normal processing. The situation is evolving as the Pentagon completes its internal review of evaluation procedures for energy projects and national security.
Summary
Federal authorities have paused approvals for roughly 165 onshore wind projects on private lands while the Pentagon reviews how energy projects are assessed for national security implications. Developers report canceled meetings, interrupted communications and lawsuits tied to classified concerns about radar interference.
