(Bloomberg) — Equinor ASA and Orsted A/S are currently in discussions with US authorities regarding security issues related to their offshore wind projects. This comes after the Trump administration announced a new set of work suspension orders.

On Monday, the US government declared a suspension of leases for all five wind farms that are being built off the East Coast, citing national security concerns. Specifically, there are worries that the wind turbines could disrupt radar systems. The combined investment for these five projects is around $28 billion, according to BloombergNEF.

The projects affected include Orsted's Revolution Wind and Sunrise Wind, both of which are set to start delivering power in 2026. Revolution Wind is expected to begin generating electricity in January, the company stated. Equinor also mentioned that its Empire Wind 1 project is currently 60% complete.

Orsted, the Danish wind developer, said it is “evaluating all options,” which may include “potential legal proceedings,” according to a statement released yesterday. Equinor confirmed that it is meeting the “relevant national security-related requirements” established over the past several years.

Both companies have stated that they are adhering to the stop-work orders issued by the Bureau of Ocean Energy Management.

President Trump has been vocal about his negative views on wind power and imposed restrictions on offshore projects shortly after taking office in January, leading to various legal disputes. Earlier this month, a federal judge ruled that the president’s ban on new projects was unlawful. Some analysts are now questioning the strength of the government's reasoning behind this latest challenge.
