The American wind industry faces a potentially existential threat.

President Trump’s executive order halting permits and leases for wind projects is starting to look like a potential existential threat to the industry’s future. Just don’t expect everyone to say it out loud.
On Monday, Trump issued an order pausing new federal approvals for wind projects, pending a “comprehensive assessment” of permitting practices, while opening the door to a review of existing leases and previously-issued permits subject to litigation. In the days following the order, lawyers, industry trade representatives, and professionals who work for renewable energy developers explained to me how this could impact essentially any wind project, even ones not sited on federal lands. Wind projects are just so large and impactful that it’s hard to avoid a federal permit.
Jason Grumet, CEO of the American Clean Power Association, told me Wednesday afternoon that a pause on federal permits would impact “probably more than half” of all wind projects under development in the U.S.
“If in fact the federal government stops issuing approvals, a significant amount of the pipeline would be interrupted,” Grumet said.
Given the high costs associated with building a wind project, and the likelihood of tariffs making that situation worse, the uncertainty produced by a potential halt to permits may also be enough to cause developers to pull the plug on projects – because even if the order itself winds up tossed out in court, that could take years.
As one renewable energy professional told me anonymously, for fear of reprisal, “If we say, well we probably have the right to do this but we have to sue the government to enforce that right, it’s probably only going to get the [project] deal done 40% of the time now.” He concluded: “It’s definitely going to chill investment.”
It’s early days, and Grumet of ACP says he’s holding out hope that the new president can be walked back from the brink. He’s focusing on the possibility that people in the administration including Trump’s picks to run the Interior and Energy Departments – Doug Burgum and Chris Wright – are willing to listen and potentially help walk back a complete and total permitting shutdown.
When asked however if suing the administration may be required, Grumet said it’s a hypothetical that could come true in the worst case scenarios.
“We’re taking it seriously. But the idea that you would have a pro-business administration trying to stop private companies from taking economically appropriate action on private land is just so out of step with the role of government that we’re expecting they’re going to clarify their intent.”
Trump’s executive order is so far-reaching because wind projects regularly need federal permits and other authorizations, even if they’re sited on private or state lands.
A commonly cited federal nexus is endangered species. Opponents of wind energy have long criticized turbines for being a potential threat to birds, but it is the case that many wind projects are collocated within or near areas for rare bird migration. Cultural heritage impacts can often also be a difficulty.
One major threat I’ve been hearing about from many in the industry flew out of left field: the Federal Aviation Administration often must clear wind projects for construction. Matt Eisenson, an expert in renewables permitting at the Columbia University Sabin Center for Climate Change Law, told me FAA approvals are required “very frequently” for wind projects because any land structure more than 200 feet tall must be approved to not be a hazard for commercial planes. And while the order didn’t cite the FAA specifically, it instructed all “relevant agencies” to wind permitting stop giving approvals related to projects, opening the door to aviation-related clearances idling on a procedural tarmac.
“It’s hard to avoid it if you’ve got anything sizable,” an attorney who works in the renewable energy industry told me, adding the total scope of impact is still unknown: “There’s nobody you could talk to who could have nearly all the answers [about Trump’s order]. And that includes developers and companies, because they don’t know either.” (It’s worth noting no industry attorney would be willing to go on the record with me because of ongoing impacts to clients.)
Then there’s the existing leases and permits. It’s easy to assume that a permit issued is a permit safe, and the Biden administration quickly rushed approvals for many wind projects, onshore and offshore, in the final days before Trump’s inauguration.
But the order left open a process to challenge existing approvals through litigation. In the offshore wind space, we’re already seeing public requests for Trump to review the leases for the MarWin project off the coast of Maryland and Delaware, and Atlantic Shores off the coast of New Jersey.
Paul Kamenar, a lawyer involved in a suit challenging Dominion Energy’s Coastal Virginia offshore wind project, says we can expect the same in his case. Kamenar is with the National Legal and Policy Center, which joined with the Heartland Institute and anti-wind group CFACT to sue the government for approving Coastal Virginia, claiming it did not consider the cumulative impacts of building the project on endangered whales.
Kamenar told me he believes the order shows Trump’s team is sympathetic to the arguments raised in the case, and he’s planning to file a request for the federal government to reconsider its permits and leasing for the project as soon as next week. Kamenar said the order provides avenues for similar challenges to many other projects.
“I think this affects all the onshore and offshore wind projects,” Kamenar said. “Some more than others. But if I were the energy company, I would be loath to continue going forward until I got clarification.”
Eisenson at Columbia told me the executive order “opened the door” to a massive range of new potential hurdles for wind development. He sees legal vulnerabilities in the executive order because there’s a history in recent case law surrounding Biden’s pauses on federal oil and gas leasing. But that’s cold comfort for an industry with such high capital costs that it describes low interest rates as its “fuel.”
“This could have a major chilling impact,” Eisenson said. “Even if the EO is unlawful, it could take years in court to invalidate an unlawful decision.”

Talking with National Grid’s Matthew Satterwhite about his new report with S&P Global.
This week’s conversation is with Matthew Satterwhite, head of U.S. policy for National Grid. This week National Grid released a report in collaboration with S&P Global I found noteworthy amidst the data center backlash, asserting that building new transmission lines can potentially reduce consumer costs. I reached out asking if we could chat about how this argument leans into the fight over hyperscale infrastructure. I found our conversation illuminating and educational.
The following Q&A was lightly edited for clarity.
Why did you make this report?
It’s all focused on our customers. We’re always looking to find ways to make sure we can provide our service in the most affordable way possible, the most efficient way possible, and we always think of transmission, but it’s fallen out of favor recently. There’s so much demand with large loads, data centers, advanced manufacturing, reshoring. There’s such a need, and a lot of the debate has been focused on what we need on the generation side. We think transmission is an answer, as well.
We focused on what we have control over — since we’re in deregulated states, the only generation we’re doing is to help states reach their renewable goals. It’s a real page-turner. We really get to the core of everything.
Can we lower customer bills with transmission? This report actually showed us that’s a good investment and helps with the resource adequacy and the constraint problems we have in the Northeast. You can bring cheaper electricity in.
With respect to concerns for everyday consumers, how much do you feel like new transmission might alleviate ordinary Americans’ concerns about rising energy prices?
When you look at the demand that’s coming, the projection is that by 2035, we’ll have to add 45 gigawatts, currently. We’re on that path right now. Transmission alone isn’t going to meet that, but the question is, how do we temper that down? What do we do as National Grid to help alleviate the need for all that demand? Can we get that somewhere else rather than in the region by building generation? It's a different version of all of the above. It’s not a generation single answer or a transmission single answer. We think transmission is a big part of that.
This also allows you to bring in cleaner energy from other places. The more robust the network is, you can have energy in different places and bring that in. It replaces the need for some of the generation to be built and pays for itself by creating a cheaper return for customers adding this.
How much of the data center backlash is affecting your transmission project planning calculus? How is it changing what lines are built in the country?
We’re focused on how we can provide the cheapest service for our customers and physics. It’s science and long-term planning. We don’t have the luxury — we can’t follow, this month we’re thinking something, someone got mad, and so we’re thinking something else. We study a lot of science and physics to figure out how to build the grid.
Do you feel like the average Joe Schmoe American sees transmission as making their life less expensive and making their electricity more reliable?
I think there’s frustration and a lack of understanding about the industry overall. There’s fear of the unknown. Are data centers really driving everything that’s happening? That’s where I think, with reports like this, the benefit of it will be that people will read this and see there’s other things we can do to address the load that we need, something different than building a bunch of generation plants.
How do the question marks around whether data centers get built affect transmission planning? How much harder is the backlash making your job?
It’s a science question. Do we do a bunch of work and then nothing happens? That’s why states put their policies out. There’s multiple studies you go through with a region and with a utility. I think that’s one reason why you see states slowing down, to make sure the policy is in check so people don’t do work they don’t need to do. It’s about having the policy to make sure, if you’re studying something, you’re doing it with a purpose.
Plus more of the week’s biggest development fights.
1. Clark County, Nevada – The first data center approved on federal lands has hit a legal brick wall.
2. Jackson County, Missouri – We have yet another high-profile case of a city councilor losing their job over voting for a data center, and this one’s a doozy.
3. Utah – What’s it take for the Bureau of Land Management to approve a big transmission line for zero-emission energy generation these days? Geothermal, baby.
4. Huntsville, Alabama – You can’t even build a tiny battery storage facility in the middle of Alabama anymore.
Where temporary moratoria could happen next.
Brace yourself for more statewide data center moratoria.
So far there are only two full state-wide blocks on data center permits, in New York and Texas. At least fifteen states have moratorium legislation in the pipeline, but few if any of those bills stand a chance of becoming law in the short term. Here are five states, however, where a broad development pause may gain momentum in the next year or two — and all of them are crucial to watch this November.
If you blinked you may have missed it: New Hampshire Governor Kelly Ayotte, a Republican, said she wants to enact a statewide data center moratorium.
Ayotte first came out in support of a pause last month at a Rotary Club meeting, declaring, “It does not make any sense at all to site a data center in New Hampshire.” She also reportedly plans to include a moratorium proposal in her upcoming 2027 fiscal budget. New Hampshire’s legislative sessions occur in the first half of the year, so we won’t see action on a moratorium bill this fall. But Ayotte’s statements suggest the Granite State — which is controlled by the GOP — could pivot to a pause very soon.
New Hampshire has very few data centers. Like, almost none. Only two project fights exist in the Heatmap Pro database, both in Portsmouth, and each has been canceled amidst opposition. Ayotte’s remarks were prompted by the fight against a hyperscale project being studied in the small town of Bow at a former coal plant that closed in late 2025.
None of this should surprise anyone familiar with New England NIMBYs. A New Hampshire moratorium also makes sense given the state’s proximity to Maine, which almost had one of its own. Ayotte, who is up for re-election this year, is likely looking at the political fortunes of Governor Janet Mills and trying to avoid potholes ahead of a likely blue wave hitting her state.
This week, Arizona Attorney General Kris Mayes, a Democrat, came out in support of a statewide data center moratorium.
Mayes told Arizonans in a public statement on Monday that she wants to avoid undue strain on the electric grid and adding to the burden of water cuts led by the Trump administration. Phoenix, where opposition grows by the day, seems to be the primary reason. This shouldn’t in any way be a surprise given the backlash to these projects, which in Arizona’s case is rooted in legitimate water security concerns.
One of the first high-profile data center conflicts I ever learned about was in Arizona: Project Blue, which had to move on from the city of Tucson after officials voted it down last summer. That led Amazon to bail from the facility, though it’s still under development elsewhere on county land. Locals are deeply concerned about the water impacts.
Ordinarily an attorney general wouldn’t have any sway on legislative or executive policy, but the state is already quite receptive to restricting data center development. Governor Katie Hobbs has enacted a three-year pause on tax abatements for data centers, and in response to requests for comment on Mayes’ statement, has told media she’s working on more policies targeting the sector. Hobbs has said she will do more in the following legislative session, but it’s not clear what.
The real decisive action here is probably going to be legislation, and that will depend on the reception any moratorium finds with Republicans in the state legislature, which is typically split in this purple state. The Arizona GOP is quite pro-industry, and Mayes’ opponent in her race for re-election opposes restricting data center construction.
You really should get to know the name Cindy Holscher for the next two months.
Holscher, a state senator, won a surprise upset victory in the Democratic gubernatorial primary this year, and currently sits within a one-point margin of her Republican opponent. How’d she get the nom? By calling for a statewide data center moratorium. “It reminds me of when the automobile manufacturers had to put seatbelts into their cars,“ Holscher told MSNOW after she won the primary. “We as a people and as a state just need to make sure there are guardrails in place.”
Kansas politics are weird. The state is best known as a conservative ideological bastion that’s pro-business. Full Republican control of the Kansas government during the Obama era led to significant social services cuts most closely associated with former Governor Sam Brownback. But after that, Kansans seemed to like moderate Democratic governors, electing Laura Kelly in 2022. Kelly is now term limited out of office.
Kansas already has a colorful patchwork of local data center and renewable energy restrictions. Land use is a big deal in this agricultural behemoth. Should Holscher win in a blue wave year, she would have a mandate to enact a statewide moratorium. Still, Republicans control the legislature, and that’s unlikely to change. My major questions are, should Holscher win, would the GOP in state government listen to Holscher’s request? Or can she do this through the executive branch?
Politics nerds are obsessing over Ohio right now. There, Trump acolyte Vivek Ramaswamy is neck-and-neck in the polls for governor with a Democratic candidate who backs a “conditional” data center moratorium: Amy Acton.
What’s a conditional moratorium? It’s in the eye of the beholder, really. Technically speaking, Governor Josh Shapiro instituted a conditional moratorium in Pennsylvania, where data center projects cannot get permits unless they meet very specific standards set by the governor himself. Shapiro did it through executive action, but in this case, it’s unclear whether the moratorium will be codified through that process or through law.
Should Acton win — or if former Senator Sherrod Brown defeats sitting Senator Jon Husted in the U.S. Senate race — I anticipate major legislative action on data centers in Ohio. Republicans there have essentially permanent control of the state legislature, and they’ve historically been pro-data center. But the freakout over opposition to artificial intelligence and hyperscalers in the senate race specifically has spooked national Republicans, who think it provided the opening Brown needed to potentially win back his seat. Acton and Brown’s political fortunes appear to be wedded to one another, linked to a general angst in the American public.
Every top 5 list needs a wild card, and mine is Oklahoma.
Currently, there’s minimal risk of a data center moratorium. I might’ve had this state higher on my list had Gentner Drummond won the runoff for the GOP gubernatorial primary, given his proclivity to side with anti-renewables activists who also oppose data centers. Instead, likely future governor Mike Mazzei is running on a more moderate, Trump-friendly approach to data centers centered on maintaining industry growth while protecting ratepayers from new infrastructure costs. His opponent, Cyndi Munson, supports a one-year moratorium.
I consider Oklahoma’s odds of having a data center moratorium about equal to the chance of a statewide wind energy ban. Momentum for anti-wind legislation began in the state legislature, and I expect the same to happen with data centers. But unlike the wind industry, which has enormous power in the state, data centers are still a nascent industry. This is a place that may take about two or three years to manifest full cultural upheaval over these projects.
