A Republican who firmly opposes Maine’s efforts to develop offshore wind power is finding political allies among those who back it. Their common ground: keep Sears Island out of it.

About a dozen people who support efforts to launch an offshore wind industry testified Wednesday in favor of two bills against developing a wind port on Sears Island, urging lawmakers on the Environment and Natural Resources Committee to consider building a terminal to assemble and store wind turbines at Mack Point instead, saying that the nearby location is already an industrial site being used by an energy and port services company.

“I’m not in opposition to wind power,” Nancy Galland, of Rockland, told the committee. “I wish it were more than a concept. It’s got a long way to go, but we need all the help we can get.”

Dianne Kopec, a University of Maine research biologist, said she favors offshore wind development to help boost economic growth and reduce greenhouse gas emissions.

“I am also strongly opposed to sacrificing the undeveloped coastal forest of Sears Island … to achieve this goal, especially when Mack Point, which is paved industrial land, sits less than a mile away and can be redeveloped from its current use as an oil terminal,” she said.

The Republican-backed legislation faces an uphill climb in the Democratic-controlled Legislature and opposition from Gov. Janet Mills, who announced with some fanfare the state’s preference for Sears Island last year.

The two bills would block development by extending a conservation easement to include the entire island and halt state efforts to seek building permits, among other measures.

Rep. Morgan Rielly, D-Westbrook, asked Rep. Reagan Paul, R-Winterport, the bills’ sponsor, her views about developing offshore wind. She said she doesn’t support it.

“I’ve never been shy about that,” she said.

Paul said she’s not against developing a port at Mack Point. “I don’t think the industry is going to survive so I think the way I’m looking at it is if they build a port we can use it for other uses besides offshore wind.”

“Sears Island should never be industrialized for any reason. That’s my stance,” Paul said.

The Mills administration has pushed back against the legislation, defending Sears Island as its preferred site. Matthew Burns at the Maine Department of Transportation said the proposed legislation to create an offshore wind port on Sears Island would restrict development to a 100-acre parcel of state-owned land. A survey has found no archaeological or historic sites in the vicinity of the proposed terminal, he said.

The agency released a report in October explaining why it considers Sears Island the best of 23 possible locations for the wind port.

Opponents of the two bills said Maine must build out an offshore wind industry to help achieve greenhouse gas reduction targets and boost manufacturing and construction jobs. “If there’s a state that should not limit its economic opportunities, it’s Maine,” said Grant Provost, a business agent for Iron Workers Local 7.

The future of wind power in Maine and elsewhere is in doubt given opposition by President Donald Trump, who is ending federal financing.

Francis Eames, executive director of the Maine Labor Climate Council, alluded to the shift in federal policy that supported offshore wind in the administration of President Joe Biden. He said a “clear majority” of Mainers supports development of Sears Island “and these bills would short-circuit that process, notwithstanding the uncertainty the federal government has put us all in.”

Maine’s efforts to launch an offshore wind industry faces other obstacles. In October — two weeks before Trump was elected — the U.S. Department of Transportation rejected Maine’s application for $456 million to build the offshore wind port at Sears Island.
