Chief U.S. District Judge Denise Casper in Boston issued a preliminary injunction that temporarily blocks the U.S. Department of the Interior and the U.S. Army Corps of Engineers from enforcing five administrative actions pending a final decision. The injunction protects clean‑energy developers from the administration's "arbitrary and capricious" efforts to hinder wind and solar projects on public land or wherever federal permits are required. The plaintiffs—Renew Northeast, Interwest Energy Alliance, and Southern Renewable Energy Association—argued that the measures "harm the public by delaying and preventing" wind and solar projects, thereby threatening the public's vital interest in a reliable, affordable, and resilient electricity grid. The coalition stated that it has demanded and received an immediate halt to the administration's unlawful permitting actions, which have discriminatorily placed wind and solar technologies into second‑class status. They added that clean energy is fast, affordable, and here to stay, and they look forward to restarting the impacted projects nationwide. According to a study by Charles River Associates referenced in the ruling, the roadblocks have led to roughly 57 GW of new wind, solar, hybrid, and offshore wind capacity being either canceled or placed at material risk of delay or cancellation beyond 2029, representing at least $905 million in sunk investment costs. The most sweeping of the five agency actions was the Interior's "senior political review bottleneck," a July 2025 directive requiring Interior Secretary Doug Burgum to review all decisions related to wind and solar projects. The memo listed nearly 70 types of permits and other items that would need Burgum's personal sign‑off, adding cost, time, and significant uncertainty to projects. Other measures stopped by the injunction include two similar directives from Interior and the Army Corps that prioritize projects generating the most energy per acre—an approach that favors coal, oil, and fossil gas and undercuts renewables. The judge also blocked Interior's new legal interpretation of the Outer Continental Shelf Lands Act that critics say essentially bars developers of offshore wind projects from obtaining new permits. An Interior spokesperson said the department does not comment on litigation but emphasized that America sets the global standard for energy production, doing it cleaner, safer, and more reliably than anywhere in the world. For clean‑energy proponents, the decision offers affirmation that the Trump administration's broad attacks against renewables do not hold up under scrutiny. Stephanie Francoeur of Oceantic Network, a trade group that advocates for offshore wind, said the series of lawsuits is building a solid record of legal decisions that prove contract law is valid in the U.S. She added that it also provides developers and the supply chain a path forward to defend investments, protect jobs, and drive energy prices down.
