Ørsted's Legal Push: Can a Court Overturn the Trump Wind Halt?

The immediate catalyst for a potential turnaround in the offshore wind sector is a legal challenge filed today. On January 1, 2026, Revolution Wind LLC, a joint venture between Ørsted and Global Infrastructure Partners, filed a lawsuit and motion for a preliminary injunction in federal court. The suit directly targets the Trump administration's lease suspension order for the $5 billion Revolution Wind project, which was issued on December 22. The core of the legal battle is whether a federal judge will find the administration's cited "national security risks" to be a legitimate basis for halting a project that is now 87% complete.

The administration's rationale, which centers on radar interference from turbine blades and towers, has already been questioned by the judiciary. This is not the first time this argument has been tested. A federal judge previously ruled that a similar stop-work order was "the height of arbitrary and capricious". That precedent gives the legal team for Revolution Wind a clear path to challenge the new suspension, arguing that the government is acting without a sound legal basis after years of thorough permitting.

The stakes are exceptionally high because the project is nearly finished. Revolution Wind has already installed 58 of 65 wind turbines and completed its export cable. At the time of the suspension, the project was expected to begin generating power as early as January 2026. This advanced stage of construction transforms the legal challenge from a theoretical dispute into a race against time. The company is seeking to protect billions of dollars in sunk costs and a project that was slated to deliver affordable power to over 350,000 homes.

The outcome of this case will set a critical precedent for the entire stalled offshore wind industry. If the court grants the preliminary injunction, it could force the administration to lift the suspension on Revolution Wind and potentially other paused projects. This would provide a much-needed shot of stability to a sector that has been repeatedly disrupted. The legal challenge, therefore, is not just about one project; it is a direct test of the government's power to halt multi-billion-dollar infrastructure on national security grounds after a project has cleared years of regulatory hurdles.

The Mechanics: Project Status and Financial Exposure

The tangible assets at risk in the Revolution Wind dispute are substantial and already built. The project is a 50/50 joint venture between Orsted and Global Infrastructure Partners' Skyborn Renewables, and it is now approximately 87 percent complete. All offshore foundations are installed, 58 of 65 turbines are in place, and the export cables and substations are finished. This is not a paper plan; it is a physical asset on the verge of operation. The financial stakes of halting it are equally concrete. The venture has already spent or committed about $5 billion on the project. If canceled, it faces more than $1 billion in new costs to decommission and write off the work already done. For the joint venture partners, this represents a massive sunk cost and a direct threat to their capital.

The project is also a critical piece of regional infrastructure. It is set to provide power to more than 350,000 homes under long-term 20-year power purchase agreements with utilities in Connecticut and Rhode Island. The regional grid operator, ISO New England, has warned that halting the project could increase electricity costs and undermine reliability for the region. This creates a direct conflict between the project's financial viability and its role in meeting growing energy demand, particularly from data centers and AI.

The legal and financial exposure extends beyond Revolution Wind itself. A separate subsidiary of Orsted, Sunrise Wind LLC, also received a lease suspension order on the same day. This indicates a broader regulatory crackdown on offshore wind projects, increasing the uncertainty and potential costs for other developments in the pipeline. The project's advanced status makes the risk of cancellation particularly acute. It has already cleared a thorough review process spanning more than nine years and secured all required federal and state permits. The company argues that the administration's move, citing national security concerns, violates the law and introduces legal uncertainty into projects that have already passed this rigorous scrutiny.

The bottom line is a high-stakes gamble. The project has already consumed billions in capital and is nearly operational. The financial exposure if it is halted is enormous, with over a billion dollars in additional losses on top of the five already spent. The regional energy system also faces tangible risks to cost and reliability. This makes the legal challenge not just a defense of a single project, but a fight to protect a massive, tangible asset and the financial commitments that have been made to build it.

The Legal and Political Battlefield

The Revolution Wind project is now at the center of a high-stakes legal and political fight, highlighting a volatile regulatory environment for offshore wind developers. Ørsted, the Danish developer, argues it has already won the battle on paper. The project secured all required federal and state permits in 2023 after a review process that began more than nine years ago. Crucially, it completed years of consultation with the Department of Defense, resulting in a fully executed formal agreement outlining mitigation measures for any national security concerns. The company contends that the December 22 lease suspension order by the Interior Department violates applicable law and poses immediate harm to a project that is already 87% complete and slated to begin generating power in early 2026.

State officials and Democratic lawmakers have slammed the administration's move as unjustified and politically driven. Governors from the affected states have written to Interior Secretary Doug Burgum, arguing that the sudden emergence of a "new" national security threat is a pretextual excuse for a predetermined outcome consistent with the president's frequent personal opposition to offshore wind. They point out that the federal government, including the DoD, had already reviewed the projects and found no threat years ago. The governors warn that this "irrational and erratic action" is a national security and economic disaster, undermining energy security and handing a strategic advantage to foreign rivals.

This case is part of a broader pattern of halting offshore wind projects. The administration's stance is consistent with a sweeping executive order issued in January that halted all new wind power approvals, which a federal judge already ruled against in December as "arbitrary and capricious and contrary to law." The latest suspension follows an earlier stop-work order from August. For developers, this creates a high-risk environment where projects can be paused just as they near completion, despite having cleared extensive permitting and interagency reviews. The legal challenge filed by Revolution Wind is a direct attempt to protect its substantial investment and the power supply commitments to more than 350,000 homes, setting a critical precedent for the industry.

Catalysts and Risks: What to Watch Next

The immediate trigger for any stock movement in Ørsted is the court's ruling on the motion for a preliminary injunction. Revolution Wind, a $5 billion project now 87% complete, filed the motion on January 1, 2026, seeking to lift the December 22 lease suspension order. The company argues the order, which cites unspecified national security concerns, is arbitrary and violates its rights. A favorable ruling could allow work to resume imminently, potentially restoring the project's timeline to deliver power as soon as January 2026. This would be a direct positive catalyst, signaling the company can overcome regulatory hurdles and protect its substantial capital investment. Conversely, a denial would force a costly delay, compounding the financial harm from the 90-day pause.

The key uncertainty is the administration's next move. The Interior Department's initial letter stated the 90-day pause "can be extended if necessary," and cited "new classified information" from the Pentagon. This creates a major risk: the administration could extend the suspension indefinitely, citing ongoing national security reviews. This would prolong the uncertainty, force further cost overruns, and signal a broader strategic retreat from the U.S. market. The governors of the affected states have already demanded a classified briefing, arguing the sudden threat is a pretext. Their push for transparency will be a critical watchpoint.

Beyond the court, investors should monitor for potential state-led lawsuits and Ørsted's evaluation of options for its other suspended project, Sunrise Wind. The company has stated it is "evaluating all options" for Sunrise Wind, which could include legal action. If multiple projects face protracted legal battles, it would signal a systemic problem for the company's U.S. growth strategy. The governors' joint statement framing the pause as a threat to "energy security" and a strategic disadvantage to rivals like China adds political pressure, but the ultimate outcome hinges on the court's interpretation of the administration's rationale and the strength of the legal challenge.
