The Grudge Match Over Maine’s Plans for Offshore Wind

Conservationists won the last round, but this time the stakes involve new renewables technology.

The future of floating offshore wind in America rests on a feud between YIMBY state officials and a government whistleblower over a bucolic island off the coast of Maine. I have no clue who will win.

Floating offshore wind is Maine’s best bet for wind power in deeper stretches of ocean, far away from beach views, coastal properties, and valuable fishing grounds. The tech — which other countries have tried to deploy but is still unproven at large commercial scale — offers a hypothetical panacea for the sorts of conflicts that often stymie offshore wind, and other states are looking to it as a solution for these thorny issues, including California.

But Maine has chosen to construct its floating offshore wind turbine assembly site at Sears Island, a naturalist tourist destination in Penobscot Bay. Conservationists in New England have fought for a long time to preserve the island, an incredibly biodiverse ecosystem rich with wetlands, from the Maine Department of Transportation, which over decades has attempted to use a section of the island for various forms of infrastructure, including an industrial port.

Now that this longstanding conflict has become intertwined with the cause of carbon reduction, it is pitting an older generation of eco-warriors against a younger breed of climate activists, as well as local unions eager to get in on energy transition jobs. Unfortunately for Maine regulators, one of the old heads opposing this project is Kyla Bennett, a former wetlands permitting staffer at the Environmental Protection Agency who stopped a previous effort by the Maine Department of Transportation to build a port at Sears Island in the 1990s.

At EPA, Bennett determined that constructing the port would’ve been illegal under the Clean Water Act because of the sheer proliferation of obvious wetlands. When political officials interceded and reassigned her to a different job, she blew the whistle on them — and won, winning back her post. The port permits were also denied.

Bennett is now a key organizer for Public Employees for Environmental Responsibility, an organization that represents whistleblowers doing environmental protection work in government. And she’s making it a hobby horse to, again, stop Sears Island from becoming a port — even if it’s in the name of developing technology that could stem the tide of climate change.

“It’s déjà vu. It’s really disturbing to me that it’s back and we have to do this all over again,” she told me.

The facility has to go somewhere because, well, the technicians and researchers need a place to build these turbines, and Maine has claimed that no port existing today on the East Coast fits the precise spacing and resource needs. Habib Dagher, a University of Maine professor who leads the consortium plotting a U.S. offshore wind industry, told me constructing a port for assembly is “critical” to near-term success.

Yet there is another option. Moffat and Nichols, the engineering firm that studied port locations for Maine regulators, did conclude Mack Point, an existing import terminal on the coast of the Penobscot owned by Sprague Energy, would also fit the bill. Sprague is proposing to pay for a large expansion of Mack Point to take this floating offshore wind business off of Sears Island. Not only does it already have existing rail infrastructure and a long history of working in energy and construction but crucially, the engineering firm also found that siting the assembly facility there would shave years off the permitting and construction timetable for making floating offshore wind a reality.

Legally, this alternative matters, and federal regulators will decide who wins this fight. Maine regulators are expected to submit paperwork to begin the permitting process under the National Environmental Policy Act for building the assembly site at Sears Island in the coming weeks. As they do so, they will be required to explain how this plan offers the “least environmentally damaging practicable alternative” under environmental law. And Bennett is confident their claims will not pass muster in court, if not with career EPA staff.

“It cannot be legally permitted,” she confessed. “We will sue them.”

So I sought out to answer this pesky question: Why is Maine trying to build this crucial infrastructure for the energy transition in a place with activist resistance, and where even its own consultants have said the process would take longer?

State regulators, politicians, and supporters of the Sears Island plan have a few reasons. First off, Maine Governor Janet Mills has bemoaned that to use Mack Point would require leasing the property from Sprague, which would mean a recurring cost to taxpayers. There are also size issues — the Maine Department of Transportation claims there simply wouldn’t be enough space at Mack Point for researchers and, eventually, industry to do their work.

“We know there would be environmental impacts at both the Mack Point and Sears Island sites,” Paul Merrill, director of communications for the Maine Department of Transportation, told me in an email Monday evening. “The bottom line is that the port Maine needs simply doesn’t fit at Mack Point. Sprague has a financial interest in development on Mack Point. Our goal is to develop a port that is in the best interest of the public.”

Merrill did acknowledge the new proposal for Sears Island would be located on “the same part of the island that was discussed for development in the 1990s.”

Sprague denies the logistical issues with building the port at Mack Point and told me issues Maine regulators are easily resolved. The company has begun campaigning to win key stakeholders to its side, publishing op-eds and meeting with environmental advocates. On September 12, Sierra Club’s Maine chapter hosted a virtual event with a Sprague executive, Jim Theriault, about how the port selection “needs to be considered carefully.” When I spoke to Theriault this week, he told me that Sierra Club members were asking the same question I was.

“At the end of the day, we’d be reusing an industrial site, and we’d relocate what we do to other parts of the terminal,” he said. “I’ll make myself available to anybody that wants to talk.”

Anti-Wind Activists Have a Big Ask for the Big Man

The Trump administration is now being lobbied to nix offshore wind projects already under construction.

Anti-wind activists have joined with well-connected figures in conservative legal and energy circles to privately lobby the Trump administration to undo permitting decisions by the National Oceanic and Atmospheric Administration, according to documents obtained by Heatmap.

Representatives of conservative think tanks and legal nonprofits — including the Caesar Rodney Institute, the Heartland Institute and Committee for a Constructive Tomorrow, or CFACT — sent a letter to Interior Secretary Doug Burgum dated February 11 requesting that the Trump administration “immediately revoke” letters from NOAA to 11 offshore wind projects authorizing “incidental takes,” a term of regulatory art referencing accidental and permissible harassment, injury, or potential deaths under federal endangered species and mammal protection laws. The letter lays out a number of perceived issues with how those approvals have historically been issued for offshore wind companies and claims the government has improperly analyzed the cumulative effects of adding offshore wind to the ocean’s existing industrialization. NOAA oversees marine species protection.

The Great Battery PR Fire of 2025

And more of the week’s biggest conflicts around renewable energy.

Renewable energy fights

1. Monterey County, California – The Moss Landing battery fire is now the big renewables PR crisis we should all be watching, even with Trump 2.0 going on.

  • Whereas before a battery fire news cycle might last a week, this story’s now in thermal runaway, as The New York Times has taken to profiling the sick and injured. Affected residents have now sued Vistra Energy, operator of the Moss Landing battery storage facility, for damages. Famed environmentalist Erin Brockovich is now involved, working in tandem with victims’ attorneys. Nearby San Luis Obispo and Orange counties have now issued temporary moratoriums on new battery storage.
  • It’s worth considering how much of this is unique to Moss Landing. The residents’ legal comaplint takes aim at the use of nickel manganese cobalt batteries (NCM) for storage, as opposed to lithium iron-phosphate (LFP) chemistries. NCM is an historically popular battery chemistry used in consumer electronics and electric vehicles … but not as often with storage.
  • “Because they are safer, most energy storage projects around the world have been transitioning to LFP batteries,” the complaint states. “NMC batteries undergo thermal runaway at a lower temperature and release more energy from decomposition, while LFP batteries can withstand higher temperatures than NCM batteries before beginning the thermal runaway process.”
  • The lawsuit also claims the fire suppression system at Moss Landing was faulty and contrasts its behavior with a fire at a “neighboring Tesla project, which used safer and less volatile LFP batteries,” and which it says was “quickly extinguished.”

2. Portage County, Wisconsin – Doral Renewables’ Vista Sands solar project is facing a prolonged legal fight with the Wisconsin Wildlife Federation, a state outdoor recreation and wildlife advocacy group. At the center of the conflict is a bird that’s long bedeviled developers of all stripes: the greater prairie chicken.

Building Renewable Energy on Castles of Sand

A look at the biggest news around renewable energy policy this week.

1. The anti-renewable locavore – Republican lawmakers are aiming to empower localities to block renewables projects, a similar scene to what’s played out in Ohio, where state legislators gave towns the power to have a final word on development instead of state-led entities.

2. Sgamma thoughts – Trump selected Kathleen Sgamma, head of the pro-oil Western Energy Alliance, to head the Bureau of Land Management. What does this mean for renewables developers? It’s hard to tell because so much of her time was spent on a single mission: liberating as much oil from the ground as possible.
