America’s energy regulators are hashing it out in the comments.

As decades of administrative law were being rendered irrelevant last week by a landmark Supreme Court decision denying regulators deference in their interpretations of ambiguous legal statues, one such regulator, Mark Christie, already had some ideas about what do with this new development.
Christie, the Federal Energy Regulatory Commission’s sole Republican member, had taken issue with FERC Order No. 1920, which was unveiled in May and established a new set of rules requiring transmission planners to be more proactive in assessing their future needs and how to pay for them. The order was decided in a 2-1 vote along partisan lines and was largely hailed by environmental and climate groups, who saw it as a way to encourage building out the transmission necessary to bring more wind and solar onto the grid.
To some conservatives, however, the order would remove states from their rightful role in the transmission planning process and stick ratepayers with the cost of infrastructure they never asked for. The rule is already being challenged by state utility commissions, Republican state attorneys general, and the country’s largest regional transmission organization in a FERC process known as request for rehearing. Lawsuits will almost certainly follow.
Those lawsuits will play out on the new terrain laid out by Loper Bright Enterprises v. Raimondo, the Supreme Court decision rendered last week, which overturned a decades-old legal principle known as Chevron deference. Named for the 1984 case Chevron v. Natural Resources Defense Council, which established the notion that courts should defer to agencies’ interpretation of ambiguous statutory language to justify their rulemaking activity, Chevron deference formed the legal foundation for much of the U.S. regulatory apparatus.
In Christie’s lengthy and impassioned dissent to the order, however, he signaled that he thought that foundation might be crumbling.
“The final rule does not deserve a shred of deference under Chevron,” Christie wrote. Unlike past transmission planning rules that had survived legal challenge, this new order was “pretextual” and “heavy handed.” An earlier transmission case case that reached the Washington, D.C. Court of Appeals in 2014, South Carolina Public Service Authority v. FERC, upholding FERC’s ability to mandate transmission planning was, Christie wrote, decided in favor of FERC because it “upheld precisely because it was only mandating processes, not outcomes,” whereas the new rule “nakedly intends to produce very specific outcomes.” Christie was basically painting a red flag on the order for the bull of the judicial process to run through.
Once Chevron deference was no longer in force, Christie issued an update to that dissent, writing in a statement on Friday that the “most important legal lifeline that Order No. 1920 needed was pulled away today, and the final rule’s chances of surviving court challenges just shrank to slim to none.” He referred to outstanding petitions for rehearing the order as “devastating takedowns.” Without Chevron to lean on, he prognosticated, “the Commission can wait for a court to strike down” 1920, or it can answer “those many petitions asking for rehearing or amendments with a new opportunity for amendments.”
In other words, the order should not have had Chevron’s protection, but now that it doesn’t, it’s toast.
On Monday, the Commission’s Democratic Chairman Willie Phillips released a statement (because there was nothing else going on in the legal world that day) arguing that the Commission’s ability to regulate both planning and the distribution of costs “has long been recognized by bipartisan majorities of the Commission and U.S. Court of Appeals for the District of Columbia Circuit,” adding that “nothing in the Supreme Court’s Loper Bright decision overturning the Chevron doctrine calls that conclusion into question.”
He also gave a preview of how the Commission will likely defend the rule in federal court. Order No. 1920 “fits easily within the South Carolina precedent,” he wrote. “It does not promote particular public policies, does not dictate specific outcomes, does not include any selection mandate whatsoever, and employs only the lightest touch possible on cost allocation by simply restating the well-established cost causation principle.”
In conclusion, according to Phillips, Christie’s statement “does not provide a logical or reasonable basis for calling into question whether we have that authority in the first place.”
“It’s not every day that two FERC commissioners just decide to release their thoughts on the latest Supreme Court case,” Ari Peskoe, the director of the Electricity Law Initiative at Harvard Law School, told me.
FERC’s likely argument rests on two legal pillars. The first is that FERC gets its authority from the Federal Power Act, which calls for utility rates to be “just and reasonable” and not “unduly discriminatory or preferential.” FERC has argued that this gives it power over practices that directly affect rates, including transmission planning, which the D.C. Circuit affirmed in South Carolina.
In a separate 2016 case, the Supreme Court ruled that FERC could make rules on practices that directly affect wholesale electricity rates but not retail sales. This case did not depend on Chevron, with Justice Elena Kagan writing in her opinion that the justices “think FERC’s authority clear.” The combined D.C. and Supreme Court precedent, Peskoe said, adds up to FERC having “authority when something directly affects rates."
But in this new legal environment, these precedents may not be enough for a fresh case against FERC's transmission planning authority.
“What does happen now? Who knows,” University of Richmond law professor Joel Eisen told me. “What you would expect now is for litigants to say that any major FERC order, including this one, is inconsistent with the statutory authority that the agency has. They would cite Loper Bright to say that the court has to make an independent judgment that FERC has interpreted law to grant authority to do sweeping change to transmission planning, and that is simply no longer the case,” Eisen said.
Much of FERC’s more than 1,300-page order is devoted to detailed analysis of the electricity market as it stands now and how it will evolve over time, justifying the new transmission planning rules. It’s this record, Eisen said, that might let the order survive in a post-Chevron world, even when FERC asserting that the Federal Power Act gives it the right to set rules may be insufficient on its own.
“That may not have been done as an explicit nod to whether a court might uphold it under Chevron going forward. “It seems to me at least that in this new landscape, what will matter is the robustness of the agency grounded in its expertise,” Eisen told me. “The voluminous record supporting 1920 may be persuasive to a federal court.”
But, as Eisen and Peskoe both warned, which federal court may be as important — if not more so — than any argument FERC makes.
Will FERC's arguments about the nature of the electricity market and precedents relating to interpretation of the Federal Power Act fly in, say, a Texas federal court in the Fifth Circuit, where state utility commissions or Republican attorneys general may file suit? District and appeals court judges in the Fifth Circuit have shown great eagerness to throw out Biden-era rules, with a federal judge in Louisiana only this week blocking the Biden administration’s pause on approving new natural gas export terminals.
“If it goes to the Fifth Circuit,” Peskoe said, “that will be bad news.”

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.
