Let's dive deep into the campaign against the so-called “high-risk” cables.

One of the biggest threats to American offshore wind is a handful of homeowners on the south Jersey shoreline spouting unproven theories about magnetic fields.
Within a year of forming, the activist group “Stop The High-Risk Cables” has galvanized local politicians against the transmission infrastructure being planned for wind turbines off the coast of New Jersey known as the Larrabee Pre-built Infrastructure. The transmission route, which will run a few miles from the beaches of Sea Girt, New Jersey, to a substation nearby, is expected to be a crucial landing zone for power from major offshore wind projects in south Jersey waters, including Atlantic Shores, a joint venture between EDF Renewables and Shell that received final permits from federal regulators last week.
The only problem: while state regulators have been busy planning the route for the transmission and selecting who will build it, opponents have managed to win the war of public opinion. Activists have clearly turned their neighbors against the plan, pushing the mayors of the four boroughs targeted for Pre-Built Infrastructure to come out against the project. And this weekend Jack Ciattarelli – who narrowly lost the race for the governor’s mansion last year and is running again in 2025 – joined activists rallying against the project and is now campaigning on ending the project and cable landings like it.
Since federal regulators control the waters, what this means is, unless Democrats hit the electoral jackpot over the next year, offshore wind in New Jersey could be screwed – even if Kamala Harris wins the White House.
What makes this more dire is, this isn’t any ol’ transmission. For other offshore wind projects like Empire Wind, states have forced developers to design and construct their own transmission landings, creating a somewhat disorganized situation resembling electrical spaghetti. New Jersey’s offshore wind transmission meanwhile has been studied for years and is supposed to minimize development on the shoreline. This means the combat over this cabling could decide the fates of multiple offshore wind projects – and the first major proactive plan to reduce beach-level environmental impacts that stymie offshore wind in the first place.
So I decided to dive deep into the campaign against the so-called “high-risk” cables. After a series of interviews with organizers and a mayor critical of the state’s processes, I’ve been left feeling this relatively small transmission project represents a true test for democracy’s role in climate action. Could a small band of organized individuals be all it takes to hold back decarbonization at the pace scientists say is necessary, no matter how many climate laws are passed?
Sea Girt resident Kimberly Paterson remembers when she first heard about the cables. Someone had left a postcard on her door about the project. Before that, the professional executive leadership trainer had devoted her activism to preserving maritime forests on the beach. Once made aware of the transmission cables though, she and her small coterie of environmentally-conscious neighbors got active.
Paterson said they also started getting looped in with an existing network of activists concerned about offshore wind infrastructure. Those activists included familiar characters to the fight over New Jersey offshore wind development.
People like Mike Dean of Save the East Coast and Cindy Zipf of Clean Ocean Action, who’ve spread theories without evidence about a spate of whale deaths being tied to pile drivers for offshore wind. She says her group’s work is focused on the cables, not offshore wind, despite the close allyship with these other actors. As she simply put it, “There’s a circle of people that you meet.”
“We do like to work with others, and communicate with others, but we’re not officially tied to any of those other groups.”
The group also started canvassing, making signage for homeowners, and holding public events. As calls for action grew, so too did the political focus on the area, as state legislators and members of Congress took up the issue.
“We have created an absolute firestorm here,” Paterson told me. ‘It is unbelievable what we’ve accomplished.”
The group is focused on what they believe to be the health risks of simply being near high-voltage power lines.
To understand their fears, think of an electric current going through a wire. The more current goes through a wire, the higher likelihood of electrical waves emanating from the current’s pathway. That’s where “electro-magnetic fields” come into play. These fields are all around us and even Earth emits them. It’s the result of an excess of energy.
The World Health Organization classifies even low amounts of electromagnetic fields as a possible carcinogen, citing studies around exposure and childhood leukemia rates. But as many environmental and health experts note, studies to date have not really linked cancer occurrences to prolonged exposure to these fields. The Bureau of Ocean Energy Management says the electro-magnetic fields created by cables for offshore wind “are well below the recommended threshold values for human exposure.” So like whales and wind, it’s something to watch out for, but there’s no evidence to date of a danger here.
Nonetheless, seeking to calm any resident’s fears of magnetic fields, the New Jersey Board of Public Utilities last week convened their first public hearing within the planned development area.
At the event, numerous officials came and spoke to the project’s safety, including the executive director of the Board. They even played a long explanatory video from a consultant they hired to review the electro-magnetic fields that would come from the cables. The full presentation laid out numerous examples of what they said were similar underground and underwater transmission lines with magnetic emissions that had no discernable impact on public health, including lines in the New Jersey-New York region.
One person moved by the presentation’s efforts on magnetic fields was Mike Mangan, mayor of Manasquan, one of the boroughs that may be selected to host some of the transmission infrastructure. Mangan told me he joined with other mayors to press the state for more transparency on the cables at the behest of concerned constituents. But he didn’t know what the state knew about the magnetic fields.
“I’ll just be candid — I was ignorant on a lot of that,” he acknowledged. Mangan said he still has “a few very serious concerns” but “I think they addressed some of the bigger concerns,” including the magnetic fields.
I’ll admit, I felt the same. So far in The Fight, we’ve chronicled examples where there are at least somewhat reasonable concerns about renewable energy development – stuff like batteries sited in wildfire risk areas and solar farms in imperiled tortoise habitat. But in this case, I watched the entire presentation online and left thinking this was essentially a non-issue.
Yet Paterson says she was unconvinced by the presentation. The projects they’re citing aren’t comparable, she claims. And then she has a laundry list of other complaints about the potential cables.
Hearing her talk about the transmission, you’d think she just doesn’t want this built under any circumstances. So I asked her if, given her allies, the goal is to stop offshore wind. An avid wildlife painter, she says no, and that she’s “very strongly in support of alternative energy.”
Well, okay. Maybe it’s political or partisan then? I asked her who she’s voting for in this year’s presidential election. “I don’t like anyone in the election to be quite honest,” she confessed, self-identifying simply as a “libertarian.” She then added: “I love the idea of Robert F. Kennedy [Jr.] revolutionizing our health-care system. That makes me very excited.”
Last week, Heatmap published a risk index of the top 10 renewable energy projects worth watching for potential cancellation or major blowback to the energy transition.
We listed Atlantic Shores in the top five, primarily citing the project’s current role as a focal point for opponents to offshore wind up and down the Atlantic coastline. Hours after the risk index was published, Atlantic Shores received its final approval from the Bureau of Ocean Energy Management.
Despite that win, we’re leaving the project on the index because the cables have to be built too – and that stands to be a more stressful fight.
It wasn’t supposed to be hard. In 2021, New Jersey passed a law granting the Board of Public Utilities the authority to supersede local governments opposing easements and other permits for offshore wind transmission cables. But that law’s permissibility under the state constitution hasn’t been tested yet, thanks to the cancellation of Orsted’s Ocean Wind project, which was set to be the likeliest battleground over cables before Atlantic Shores.
State officials are expected in the coming weeks to lay out who will actually build the transmission infrastructure and the route it’ll take from Sea Girt to the Larrabee substation. Between the day of that announcement and the completion of construction, a lot can go awry. Donald Trump could win the presidency and, as opponents of offshore wind expect, revisit permitting decisions for projects like Atlantic Shores. Or a Republican like Jack Ciattarelli could win the governor’s mansion, and that person could take any number of steps to undermine the cables like leaving the local control law undefended in state court if it’s challenged.
All this risk to the energy transition, started by a handful of actors with unfounded claims about magnetic fields.
I asked Atlantic Shores for comment on the opposition movement. They did not get back to me.
However, I did hear from the New Jersey Offshore Wind Alliance, a consortium of developers trying to build offshore wind off the state coast. “While we are advocates of civil discourse and engagement from communities, we urge residents to be mindful of prevalent misinformation,” said Paulina O’Connor, executive director of the alliance, in a statement sent to me Tuesday evening.
“By following best practices in environmental science and engineering, such as proper siting, minimizing disruption during construction, and adherence to all state and federal regulations, this infrastructure can be safely and responsibly integrated into our communities and local and regional power grids to provide resilient and reliable power to New Jersey homes,” O’Connor continued.
I also heard from Anjuli Ramos-Busot, executive director of Sierra Club’s New Jersey chapter, who contacted me last night after Atlantic Shores and the offshore wind alliance brought my reporting to their attention.
“Let us be clear, the microwave in your kitchen emits more electromagnetic currents than cables buried deep underground covered by insulation and concrete,” Ramos-Busot said in a statement. “This technology is vetted, goes through rigorous permitting standards, and is safe and responsible for both the environment and local communities.”
Candidly, I’m holding my breath on whether Sierra Club’s words will win over these concerned shore residents.

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.
