President Donald Trump’s cessation of new offshore wind projects as one of his first matters of business sent a chill throughout the multi-billion dollar industry that’s taken root across the nation.

Advocates in New England, however, are confident the region’s wind projects already fully permitted by the feds are likely untouchable to the Trump administration, such as Vineyard Wind 1, Revolution Wind and New England Wind 1 and 2.

Federal interference would undoubtedly end up in court and require the government to provide compensation to developers for any losses.

“Our overall feeling is that those projects that are already fully permitted are in pretty good shape,” said Kate Sinding Daly, senior vice president for law and policy at the Conservation Law Foundation.

Projects earlier in the process, however, are likely entangled in uncertainty.

Trump’s offshore wind executive order, signed on Inauguration Day, halted all new offshore wind leases in federal waters and directed the Secretary of the Interior to “conduct a comprehensive review of the ecological, economic and environmental necessity of terminating or amending any existing wind energy leases, identifying any legal bases for such removal.”

The executive order also states, “Nothing in this withdrawal affects rights under existing leases in the withdrawn areas.”

Revoking existing federal permits or leases would not be “easily accomplished legally,” Sinding Daly said.

Trump’s efforts to stifle wind development come during a major growth spurt for the industry, one that is expected to create 56,000 jobs nationally and invest $65 billion in the economy by 2030, according to a market report released last summer by American Clean Power, an industry group representing renewable energy companies.

“While it’s not helpful that these executive orders are coming out, they can’t unring the bell,” Jeremy McDiarmid, who oversees state and regional policy activities in New England for Advanced Energy United, said of the clean energy momentum.

Gov. Maura Healey has said Massachusetts will continue to support the offshore wind industry and its injection of jobs. She noted “a lot of governors,” in both red and blue states, have “gone big on offshore wind.”

Others are pleased with Trump’s day-one actions to pull back on offshore wind.

“After four years of rushing leases and approvals to wind industry insiders, President Trump’s new directive will bring fairness and order to offshore wind development,” said Jerry Leeman, CEO of the New England Fishermen’s Stewardship Association, an anti-wind organization. “Anyone committed to protecting our natural resources should welcome these changes.”
