NORFOLK, Va. (AP) — The developers of a Virginia offshore wind project are asking a federal judge to block a Trump administration order that halted construction of their project, along with four others, over national security concerns.

Dominion Energy Virginia said in its lawsuit filed late Tuesday that the government’s order is “arbitrary and capricious” and unconstitutional. The Richmond-based company is developing Coastal Virginia Offshore Wind, a project it says is essential to meet dramatically growing energy needs driven by dozens of new data centers.

The Interior Department did not detail the security concerns in blocking the five projects on Monday. In a letter to project developers, Interior’s Bureau of Ocean Energy Management set a 90-day period — and possibly longer — “to determine whether the national security threats posed by this project can be adequately mitigated.”

The other projects are the Vineyard Wind project under construction in Massachusetts, Revolution Wind in Rhode Island and Connecticut and two projects in New York: Sunrise Wind and Empire Wind. Democratic governors in those states have vowed to fight the order, the latest action by the Trump administration to hobble offshore wind in its push against renewable energy sources.

Dominion’s project has been under construction since early 2024 and was scheduled to come online early next year, providing enough energy to power about 660,000 homes. The company said the delay was costing it more than $5 million a day in losses solely for the ships used in round-the-clock construction, and that customers or the company would eventually bear the cost.

Dominion called this week’s order “the latest in a series of irrational agency actions attacking offshore wind and then doubling down when those actions are found unlawful.”

The Bureau of Ocean Energy Management didn’t immediately respond to an email seeking comment.

U.S. District Judge Jamar Walker set a hearing for 2 p.m. Monday on Dominion’s request for a temporary restraining order.
