Compared with the optimism on display just two years ago, when more than a dozen companies competed in a three-day bidding war for the right to develop six areas off the coast of New York and New Jersey, Tuesday’s sale was a flop. Just two companies participated. The bidding closed after one round. The leases sold for a flat $50 per acre, compared to an average of nearly $9,000 per acre in the New York sale.
But put in context of how things are going in 2024, it’s a miracle anyone showed up at all. The offshore wind industry has been struggling with supply chain issues and inflation, not to mention increasing opposition from coastal communities. Just a month ago, an offshore wind lease sale off the coast of Oregon was canceled after the Bureau of Ocean Energy Management learned that there was only one interested party. The agency also canceled an auction for the Gulf of Mexico earlier this year citing a lack of interest.
“It’ll be a win if anything gets leased,” Francis Eanes, executive director of the Maine Labor Climate Council, told me Tuesday morning before the results came in. “And honestly, it won’t be surprising if it doesn’t.”
Outside of the existential threat of a Trump presidency, developing wind projects in the Gulf of Maine was already a challenging prospect. The water is upwards of 200 meters deep — too deep to affix the foundation of a wind turbine to the seafloor. Instead, developers will need to build floating structures that are moored to the seabed with giant cables. Floating offshore wind is a proven technology — there are a handful of projects already operating around the world. But it is more expensive to build, and there are none yet operating in the U.S. The National Renewable Energy Laboratory estimates that floating offshore wind farms will have a levelized cost of energy that’s at least 40% higher than fixed-bottom projects.
On top of that, just days ago, the U.S. Department of Energy rejected Maine’s application for a $456 million grant to build a floating offshore wind assembly port on Sears Island, a protected area in Penobscot Bay about the size of New York City’s Central Park. A new port is a necessary prerequisite for developing projects in the Gulf of Maine, as floating offshore wind assembly requires different infrastructure than fixed-bottom projects.
Nonetheless, Tyler Hansen, a research associate studying offshore wind at Dartmouth College, told me he thought the results of the auction “make sense” when weighing the prospects for the technology against the political risks. He expects the cost of floating offshore wind to come down as governments around the world invest in research and development. The Department of Energy has a “Floating Offshore Wind Shot,” a program aimed at reducing the cost of floating technology 70% by 2030.
The winds that blow over the Gulf of Maine are especially strong and steady, making them one of the best potential renewable energy resources in the United States. The northeast is also “particularly blessed” with available substations where projects could connect to the grid, Eric Hines, a civil and environmental engineering professor at Tufts University told me. Several recent coal plant closures on the Massachusetts coast have created “an enormous amount of coastal transmission capacity that are prime locations for plugging in offshore wind,” he said.
The area also boasts favorable policy paired with relatively strong grassroots support. States in the Northeast are counting on floating offshore wind to hit their climate goals. Maine has set a goal of achieving 100% clean electricity by 2040, with at least 3 gigawatts of power prescribed to come from the Gulf. Massachusetts, too, anticipates needing some 23 gigawatts from offshore wind by 2050, with at least 10 coming from the Gulf of Maine.
Environmental groups in Maine have spent the past two years building political coalitions with fishermen, tribes, and labor unions in support of developing an offshore wind industry. Those efforts culminated in a major victory last summer when the state passed a bill that set strong labor standards for offshore wind development, created a requirement for tribal engagement in project development, and enshrined a policy of avoiding development in a key fishery known as Lobster Management Area One. Later, the Bureau of Ocean Energy Management amended its map of lease areas in the Gulf of Maine to exclude that management area.
“That was a huge win,” Eanes said, and never would have happened without the environmental and labor movement’s proactive efforts to build consensus around where offshore wind should happen, if it were going to happen. As a result, they’ve been able to cultivate a different attitude toward offshore wind in Maine than you will find right now in New Jersey, for example.
“To be clear, if you go to a coastal community in Maine, especially one that lands a lot of lobsters, you’re not going to find support for offshore wind,” he said. “But the level of organized opposition has not been as pitched as it would have been had we seen lease areas in Lobster Management Area One.”
In a press release, Avangrid touted the Gulf of Maine’s strong wind speeds and access to interconnection, as well as the fact that it was “largely deconflicted from other ocean users following a rigorous federal public engagement process.” The company is already developing more than 5 gigawatts of offshore wind along the East Coast, including Vineyard Wind, which is currently under construction. This will be its first project to utilize floating technologies, however it is also owned by Iberdrola, a Spanish company with a pipeline of floating offshore wind projects in Europe.
Maine officials celebrated the results of the auction on Tuesday.
“The federal lease sale represents a significant milestone for Maine and the region as we advance offshore wind in a responsible manner to help us reduce our reliance on expensive, harmful fossil fuels, diversify our sources of energy, grow our economy, and fight climate change,”said Dan Burgess, Director of the Maine Governor’s Energy Office, in an emailed statement.
The Maine Department of Transportation, the agency leading the development of the would-be port, emphasized that it's undeterred despite losing out on the federal grant. “Maine has a once-in-a-lifetime opportunity to develop a port facility to create good-paying jobs while serving the entire region as we harness abundant clean wind energy in the Gulf of Maine,” Bruce Van Note, the transportation commissioner, said in a statement last week. “Our work will continue as we examine other opportunities to secure funding to advance this critical port infrastructure.”
The agency anticipates filing federal permit applications for the project in the next few months, kicking off a process anticipated to take two years, and securing additional funding for it by the end of 2025. But that timeline may depend on the results of the presidential election next week.
While it’s not always the best advice to take Donald Trump at his word, the former president promised supporters at a rally in New Jersey in May that he would “end” offshore wind development. “You won’t have to worry about Governor Murphy’s 157 windmills,” he said. “I’m going to write it out in an executive order. It’s going to end on day one.”
In its most recent quarterly market report, the industry association Oceantic Network noted that private investment and activity in the offshore wind sector “are decelerating … due largely to the uncertainty around the presidential election.”
At the same time, developers are used to long time horizons. Offshore wind projects can take a decade to permit and build, and as long as state support doesn’t slide, a slowdown of four years isn’t make-or-break. Even with a supportive administration, it will likely be impossible for Avangrid or Invenergy to begin construction in the Gulf of Maine before 2030, as that’s the absolute soonest Maine expects to get its port built.
The fact that two developers took the leap now rather than waiting for 2028 — which is when the next lease sale in the Gulf of Maine is scheduled — shows some level of confidence in the long-term prospects for the industry.
“These leases don’t come up for auction very often,” Hines told me. “And if you don’t have a lease, you can’t build a project.”
