WASHINGTON — The Trump administration has directed five large-scale wind projects under construction off the East Coast to suspend their activities for at least 90 days, according to letters from the Interior Department obtained Tuesday by The Associated Press, which provide new details on the government's move to pause the offshore ventures.
During the pause, the Interior Department will coordinate with project developers ''to determine whether the national security threats posed by this project can be adequately mitigated,'' the Bureau of Ocean Energy Management said in a letter to project developers. The 90-day period can be extended if necessary, the ocean management agency said.
The administration announced Monday it was suspending the offshore wind projects because of national security concerns. Its announcement did not indicate whether the pause was limited, nor did it reveal specifics about the national security concerns.
It was the latest step by the Trump administration to hobble offshore wind in its push against renewable energy sources. It comes two weeks after a federal judge struck down President Donald Trump's executive order blocking wind energy projects, calling it unlawful. The move angered local officials who have supported the projects and posed a new threat to offshore wind development that has faced increasing pressures since Trump took office.
The letter to the developers said the Defense Department completed a recent assessment regarding the national security implications of offshore wind projects and provided senior leadership at Interior with new classified information, ''including the rapid evolution of relevant adversary technologies and the resulting direct impacts to national security from offshore wind projects.''
The potential impacts are ''heightened by the projects' sensitive location on the East Coast and the potential to cause serious, immediate and irreparable harm to our great nation,'' the letter said. The letter was signed by Matthew Giacona, the acting director of BOEM and a former lobbyist for the National Ocean Industries Association.
Kirk Lippold, a national security expert and former Commander of the USS Cole, said concerns about wind turbines' possible effects on radar systems ''have been known for decades.''
While Interior Secretary Doug Burgum said new classified information indicates turbines may pose a national security threat, ''I want to know what's changed?'' Lippold said in an interview on Tuesday. ''What threat vector has changed? Have the Chinese developed new weapons or techniques that we're unaware of and can't fight against?''
