EnergyOMNI's Perspectives｜U.S. Clean Power Groups Sue Pentagon Over Delays in Wind Project Permitting

Edited by EnergyOMNI

Earlier this year, media reports revealed that since August 2025, the U.S. Department of Defense (DoD) under the Trump administration has effectively frozen the administrative review process for 165 onshore wind projects. The DoD halted the countersignature of final agreements and gradually slowed down other stages of the review process, until all review procedures came to a complete standstill in April 2026. In response, nine groups, including Renewable Northwest and Advanced Power Alliance, filed a lawsuit against the DoD in June, arguing that the federal government's inaction has effectively halted all new development activities and poses an existential threat to the U.S. wind energy industry.

The DoD's Siting Clearinghouse and the Federal Aviation Administration (FAA) are jointly responsible for reviewing structures taller than 200 feet (61 meters), including wind turbines, to assess potential impacts on military operations and aviation safety. However, meetings between developers and government agencies have reportedly been canceled, and project applications have not been accepted for review. The DoD has stated that it continues to evaluate the national security implications of relevant projects, but the process requires coordination among multiple agencies, making it complex and time-consuming.

According to CleanTechnica, since the DoD began reviewing energy projects in 2011 to ensure that they do not create direct conflicts with military facilities, only one project among thousands reviewed has been determined to pose an unacceptable national security risk. The American Clean Power Association (ACP) also stated that the review process, which had operated smoothly for 15 years, was disrupted beginning in mid-2025.

In May this year, 55 members of the House of Representatives sent a joint letter to Defense Secretary Pete Hegseth, stating that the DoD's review process had "effectively ceased functioning" at every stage. These stages include the initial determination of whether a project presents a presumed risk, mitigation negotiations for projects identified as posing risks, execution of mitigation agreements, countersignature of final agreements by the Assistant Secretary, and the issuance and transmission of final determinations to the FAA. All of these procedures have reportedly come to a halt.

The affected onshore wind projects represent approximately 30 GW of total installed capacity. The stalled developments have put at risk employment opportunities across 21 states and investments totaling as much as US$47 billion. Most of these projects are concentrated in states with strong wind resources, including Texas, Kansas, and Illinois. Among the 21 affected states, 13 voted for Donald Trump in the 2024 presidential election. The affected projects are estimated to support more than 120,000 jobs, including approximately 29,000 direct construction jobs, more than 80,000 indirect and induced jobs, and nearly 10,000 operations-related jobs during the wind farms' operational phase.

In response, the Department of Defense stated that, because the matter is currently under litigation, it would not comment on pending cases.
