Coastal Virginia Offshore Wind will resume construction, after a federal judge Friday temporarily lifted the Trump administration’s suspension of the project.

It is the largest offshore wind project under construction in the U.S. Shares of Dominion Energy

, the owner and developer, rose about 1% on the news.

The Department of Interior in December halted construction of five wind farms off the East Coast, including Coastal Virginia Offshore Wind, claiming national security concerns.

Judge Jamar Walker of the U.S. District Court for the Eastern District of Virginia granted Dominion’s request for a preliminary injunction Friday. Dominion called the Trump suspension “arbitrary and illegal” in its lawsuit.
