House Republicans’ new plan to transform NEPA, explained

A powerful House Republican committee has proposed shaking up one of the country’s key permitting laws as part of the ongoing process to write President Trump’s tax bill.
A new bill, drafted by the House Natural Resources Committee would transform the National Environmental Policy Act, or NEPA. Under NEPA as it stands today, the government must study the environmental impact of any “major” federal action. Any time a federal agency adopts a new policy, builds a new project, spends federal dollars, or issues a license or permit, that choice gets a full environmental review.
Crucially, this also means that the federal government must study the environmental impact even of privately developed projects that require some kind of federal sign-off. But the new bill would quicken this process and likely shield it from court review.
The law represents a “big step” for permitting reform, Nicholas Bagley, a University of Michigan law professor, told us. “It’s creative and extremely aggressive.” If it passes, Republicans’ budget measure could speed up the construction of energy projects around the country. But it could also reduce local or environmental groups’ ability to sue to slow down or block development.
The bill would allow companies to pay a fee to access a faster, more streamlined NEPA process that would not be reviewable by the courts, according to the bill. That means environmental groups would likely have a harder time suing the government for failing to account for various environmental maladies in their study.
Under the draft legislation, companies would pay 125% of the cost of preparing the report to get an expedited review. But avoiding a lengthy court fight is so valuable that many companies would likely take advantage of this new process, Bagley told us.
“You can read it as effectively creating a price for a litigation shield — the federal government is allowing developers to buy themselves out of litigation risk with a flat fee,” he said.
It would change the status quo in two important ways.
First, many federal agencies already require project sponsors to pay the full cost of preparing a NEPA report for a private project, such as a solar farm or geothermal well. The House Republican proposal would increase this cost by just 25% on the front end.
Second, under the law today, agencies take more than four years on average to prepare a NEPA report, which can regularly stretch into the hundreds of pages. Congress has periodically tried to impose tighter deadlines and shorter page limits on the NEPA process — including in a 2023 debt ceiling law — but it hasn’t been successful.
That’s because the threat of lawsuits ultimately drives the NEPA process, Bagley said. Civil servants write lengthy, meticulous NEPA reports not because statute requires them to do so, but because they’re afraid of losing their work in a lawsuit, he said.
“The thing driving lengthy timelines is litigation risk,” Bagley told us. “Unless and until you correct for the threat of judicial review, NEPA reform isn’t going to go that far.” This proposal is the first modern NEPA report to offer protection from judicial review.
The proposal could help speed up all types of energy projects.
But it could help some more than others. Certain fossil fuel projects — especially those involving fracking — have already received some form of exemption from the NEPA process. But renewables and clean energy projects broadly don’t have such a carve-out. Neither do some other types of natural gas infrastructure, such as pipelines and export terminals. These projects could benefit from a faster and less court-reviewable NEPA process.
This is the big question. To comply with the strictures of what’s known as the “Byrd Rule,” provisions in reconciliation must be primarily budgetary in nature, i.e. related to taxing and spending.
Provisions that have a budgetary effect but are “merely incidental” to their non-budgetary components can be ruled by the Senate Parliamentarian to be “extraneous” and excluded from the bill.
Parliamentarian rulings helped shape — and narrow — Democratic proposals in 2021 and 2022, including stripping out immigration provisions and minimum wage hikes from various bills that were working their way through the reconciliation process.
So where does overhauling NEPA fit in? The 125% fee makes the provisions of the House language arguably germane to the budgetary purposes of the reconciliation package. Supporters of the language will cite a precedent in the Inflation Reduction Act that waived judicial review for the program’s negotiation of drug prices in Medicare.
One way the parliamentarian will try to answer this question is by asking, “‘Is that big policy change necessary in order to achieve the budgetary impact?’ That’s the place where this could fail,” Thomas Hochman, the director of infrastructure policy at the Foundation of American Innovation, told us.
NEPA isn’t the only law that requires the government to study the environmental or cultural impact of its decisions. A handful of other laws — including the Endangered Species Act, the National Historic Preservation Act, or the Clean Water Act — mandate their own permitting process, which can also be lengthy.
Many of these laws impose substantive obligations on government decisions. The NHPA, for instance, requires the government to study whether any decisions will affect Native American cultural sites and to reach an agreement about how to mitigate that impact. These decisions can then be reviewed by the courts — NHPA was at the heart of the Dakota Access pipeline and SunZia cases.
Under the law today, the government often satisfies its duties under these laws as part of a broader “NEPA process,” with one agency essentially handling the paperwork for all the federal permitting laws that matter to a project together.
The House Republican proposal wouldn’t weaken or affect any of these laws, Hochman and Bagley told us. The government would still need to satisfy its obligations under all other federal permitting laws, and the courts could still review those decisions. It’s unclear how those laws would fit into the new streamlined NEPA process.
Senator Joe Manchin of West Virginia led two efforts during the Biden years to pass permitting reform legislation through the conventional lawmaking process. The bills tended to combine policy asks from Republicans and Democrats — that is, oil and gas interests as well as green energy and transmission developers — in an effort to build a broad consensus in favor of policy change.
What that looked like in practice was specific carveouts designed to facilitate the building of long-range transmission lines alongside, say, changes in schedules for leases for extracting fossil fuels on public lands.
This time, Republicans alone are driving the permitting reform process, because the reconciliation bill is expected to be approved (or not) on party lines.
The reconciliation language says nothing specific about transmission, for example, but it includes specific provisions favored by the oil and gas industry like mandating lease sales on a quarterly basis. The American Petroleum Institute praised the bill, and the Sierra Club said that “the only way it could be friendlier to Big Oil CEOs would be if they wrote it themselves.”
But the reform to how NEPA is — and isn’t — litigated is a genuine breakthrough in years of drawing up failed permitting reform plans.
“We haven’t yet seen one bipartisan bill on permitting that broadly amends judicial review,” Xan Fishman, senior managing director of the energy program at the Bipartisan Policy Center, told us.
“One of the difficulties in doing permitting reform is that there isn’t just one problem that needs solving. There are a bunch of things that all add up to a really difficult process that takes a long time and has massive degrees of uncertainty,” Fishman said.
To the extent clean energy projects face sometimes fatal delays due to the specific rigors of the NEPA process, the bill would remove a barrier to their development.
NEPA has proven to be a significant barrier to solar development. About two thirds of solar projects that were assessed under NEPA between 2010 and 2018 faced litigation, as well as almost one third of pipelines and 38% of wind projects, according to Stanford researchers Michael Bennon and Devon Wilson.
Even when agencies win court cases — which can be filed up to six years after a federal agency decision — “litigation overwhelmingly functions as a form of delay,” according to Breakthrough Institute research.
It’s unclear whether the House Republican proposal will ultimately speed up federal energy project approvals, or whether litigants will shift to opposing projects under other permitting laws, such as the Endangered Species Act or NHPA. But permitting reform advocates agree that the proposal nonetheless represents a big step.
“It would be a pretty good shield for persnickety criticisms of [environmental reviews] that are now de rigueur, but it might not provide complete protection from the full run of environmental objections waged against a project,” Bagley said.
“I am firmly convinced that NEPA is a big problem for helping to create and reinforce defensiveness on the part of agency officials. But it’s part of a big web of accountability run maybe too amok,” he said. “One answer is to start clipping parts of the web — it doesn’t fix the whole problem, but it might help you see what else becomes salient.”

The fourth-generation gas-cooled reactor company ZettaJoule is setting up shop at an unnamed university.
The appeal of next-generation nuclear technology is simple. Unlike the vast majority of existing reactors that use water, so-called fourth-generation units use coolants such as molten salt, liquid metal, or gases that can withstand intense heat such as helium. That allows the machines to reach and maintain the high temperatures necessary to decarbonize industrial processes, which currently only fossil fuels are able to reach.
But the execution requirements of these advanced reactors are complex, making skepticism easy to understand. While the U.S., Germany, and other countries experimented with fourth-generation reactors in earlier decades, there is only one commercial unit in operation today. That’s in China, arguably the leader in advanced nuclear, which hooked up a demonstration model of a high-temperature gas-cooled reactor to its grid two years ago, and just approved building another project in September.
Then there’s Japan, which has been operating its own high-temperature gas-cooled reactor for 27 years at a government research site in Ibaraki Prefecture, about 90 minutes north of Tokyo by train. Unlike China’s design, it’s not a commercial power reactor. Also unlike China’s design, it’s coming to America.
Heatmap has learned that ZettaJoule, an American-Japanese startup led by engineers who worked on that reactor, is now coming out of stealth and laying plans to build its first plant in Texas.
For months, the company has quietly staffed up its team of American and Japanese executives, including a former U.S. Nuclear Regulatory Commission official and a high-ranking ex-administrator from the industrial giant Mitsubishi. It’s now preparing to decamp from its initial home base in Rockville, Maryland, to the Lone Star State as it prepares to announce its debut project at an as-yet-unnamed university in Texas.
“We haven’t built a nuclear reactor in many, many decades, so you have only a handful of people who experienced the full cycle from design to operations,” Mitsuo Shimofuji, ZettaJoule’s chief executive, told me. “We need to complete this before they retire.”
That’s where the company sees its advantage over rivals in the race to build the West’s first commercial high-temperature gas reactor, such as Amazon-backed X-energy or Canada’s StarCore nuclear. ZettaJoule’s chief nuclear office, Kazuhiko Kunitomi, oversaw the construction of Japan’s research reactor in the 1990s. He’s considered Japan’s leading expert in high-temperature gas reactors.
“Our chief nuclear officer and some of our engineers are the only people in the Western world who have experience of the whole cycle from design to construction to operation of a high temperature gas reactor,” Shimofuji said.
Like X-energy’s reactor, ZettaJoule’s design is a small modular reactor. With a capacity of 30 megawatts of thermal output and 12 megawatts of electricity, the ZettaJoule reactor qualifies as a microreactor, a subcategory of SMR that includes anything 20 megawatts of electricity or less. Both companies’ reactors will also run on TRISO, a special kind of enriched uranium with cladding on each pellet that makes the fuel safer and more efficient at higher temperatures.
While X-energy’s debut project that Amazon is financing in Washington State is a nearly 1-gigawatt power station made up of at least a dozen of the American startup’s 80-megawatt reactors, ZettaJoule isn’t looking to generate electricity.
The first new reactor in Texas will be a research reactor, but the company’s focus is on producing heat. The reactor already working in Japan, which produces heat, demonstrates that the design can reach 950 degrees Celsius, roughly 25% higher than the operating temperature of China’s reactor.
The potential for use in industrial applications has begun to attract corporate partners. In a letter sent Monday to Ted Garrish, the U.S. assistant secretary of energy in charge of nuclear power — a copy of which I obtained — the U.S. subsidiary of the Saudi Arabian oil goliath Aramco urged the Trump administration to support ZettaJoule, and said that it would “consider their application to our operations” as the technology matures. ZettaJoule is in talks with at least two other multinational corporations.
The first new reactor ZettaJoule builds won’t be identical to the unit in Japan, Shimofuji said.
“We are going to modernize this reactor together with the Japanese and U.S. engineering partners,” he said. “The research reactor is robust and solid, but it’s over-engineered. What we want to do is use the safety basis but to make it more economic and competitive.”
Once ZettaJoule proves its ability to build and operate a new unit in Texas, the company will start exporting the technology back to Japan. The microreactor will be its first product line.
“But in the future, we can scale up to 20 times bigger,” Shimofuji said. “We can do 600 megawatts thermal and 300 megawatts electric.”
Another benefit ZettaJoule can tap into is the sweeping deal President Donald Trump brokered with Japanese Prime Minister Sanae Takaichi in October, which included hundreds of billions of dollars for new reactors of varying sizes, including the large-scale Westinghouse AP1000. That included financing to build GE Vernova Hitachi Nuclear Energy’s 300-megawatt BWRX-300, one of the West’s leading third-generation SMRs, which uses a traditional water-cooled design.
Unlike that unit, however, ZettaJoule’s micro-reactor is not a first-of-a-kind technology, said Chris Gadomski, the lead nuclear analyst at the consultancy BloombergNEF.
“It’s operated in Japan for a long, long time,” he told me. “So that second-of-a-kind is an attractive feature. Some of these companies have never operated a reactor. This one has done that.”
A similar dynamic almost played out with large-scale reactors more than two decades ago. In the late 1990s, Japanese developers built four of GE and Hitachi’s ABWR reactor, a large-scale unit with some of the key safety features that make the AP1000 stand out compared to its first- and second-generation predecessors. In the mid 2000s, the U.S. certified the design and planned to build a pair in South Texas. But the project never materialized, and America instead put its resources into Westinghouse’s design.
But the market is different today. Electricity demand is surging in the near term from data centers and in the long term from electrification of cars and industry. The need to curb fossil fuel consumption in the face of worsening climate change is more widely accepted than ever. And China’s growing dominance over nuclear energy has rattled officials from Tokyo to Washington.
“We need to deploy this as soon as possible to not lose the experienced people in Japan and the U.S.,” Shimofuji said. “In two or three years time, we will get a construction permit ideally. We are targeting the early 2030s.”
If every company publicly holding itself to that timeline is successful, the nuclear industry will be a crowded field. But as history shows, those with the experience to actually take a reactor from paper to concrete may have an advantage.
It’s now clear that 2026 will be big for American energy, but it’s going to be incredibly tense.
Over the past 365 days, we at The Fight have closely monitored numerous conflicts over siting and permitting for renewable energy and battery storage projects. As we’ve done so, the data center boom has come into full view, igniting a tinderbox of resentment over land use, local governance and, well, lots more. The future of the U.S. economy and the energy grid may well ride on the outcomes of the very same city council and board of commissioners meetings I’ve been reporting on every day. It’s a scary yet exciting prospect.
To bring us into the new year, I wanted to try something a little different. Readers ask me all the time for advice with questions like, What should I be thinking about right now? And, How do I get this community to support my project? Or my favorite: When will people finally just shut up and let us build things? To try and answer these questions and more, I wanted to give you the top five trends in energy development (and data centers) I’ll be watching next year.
The best thing going for American renewable energy right now is the AI data center boom. But the backlash against developing these projects is spreading incredibly fast.
Do you remember last week when I told you about a national environmental group calling for data center moratoria across the country? On Wednesday, Senator Bernie Sanders called for a nationwide halt to data center construction until regulations are put in place. The next day, the Working Families Party – a progressive third party that fields candidates all over the country for all levels of government – called for its candidates to run in opposition to new data center construction.
On the other end of the political spectrum, major figures in the American right wing have become AI skeptics critical of the nascent data center buildout, including Florida Governor Ron DeSantis, Missouri Senator Josh Hawley, and former Trump adviser Steve Bannon. These figures are clearly following the signals amidst the noise; I have watched in recent months as anti-data center fervor has spread across Facebook, with local community pages and groups once focused on solar and wind projects pivoting instead to focus on data centers in development near them.
In other words, I predicted just one month ago, an anti-data center political movement is forming across the country and quickly gaining steam (ironically aided by the internet and algorithms powered by server farms).
I often hear from the clean energy sector that the data center boom will be a boon for new projects. Renewable energy is the fastest to scale and construct, the thinking goes, and therefore will be the quickest, easiest, and most cost effective way to meet the projected spike in energy demand.
I’m not convinced yet that this line of thinking is correct. But I’m definitely sure that no matter the fuel type, we can expect a lot more transmission development, and nothing sparks a land use fight more easily than new wires.
Past is prologue here. One must look no further than the years-long fight over the Piedmont Reliability Project, a proposed line that would connect a nuclear power plant in Pennsylvania to data centers in Virginia by crossing a large swathe of Maryland agricultural land. I’ve been covering it closely since we put the project in our inaugural list of the most at-risk projects, and the conflict is now a clear blueprint.
In Wisconsin, a billion-dollar transmission project is proving this thesis true. I highly recommend readers pay close attention to Port Washington, where the release of fresh transmission line routes for a massive new data center this week has aided an effort to recall the city’s mayor for supporting the project. And this isn’t even an interstate project like Piedmont.
While I may not be sure of the renewable energy sector’s longer-term benefits from data center development, I’m far more confident that this Big Tech land use backlash is hitting projects right now.
The short-term issue for renewables developers is that opponents of data centers use arguments and tactics similar to those deployed by anti-solar and anti-wind advocates. Everyone fighting data centers is talking about ending development on farmland, avoiding changes to property values, stopping excess noise and water use, and halting irreparable changes to their ways of life.
Only one factor distinguishes data center fights from renewable energy fights: building the former potentially raises energy bills, while the latter will lower energy costs.
I do fear that as data center fights intensify nationwide, communities will not ban or hyper-regulate the server farms in particular, but rather will pass general bans that also block the energy projects that could potentially power them. Rural counties are already enacting moratoria on solar and wind in tandem with data centers – this is not new. But the problem will worsen as conflicts spread, and it will be incumbent upon the myriad environmentalists boosting data center opponents to not accidentally aid those fighting zero-carbon energy.
This week, the Bureau of Land Management approved its first solar project in months: the Libra facility in Nevada. When this happened, I received a flood of enthusiastic and optimistic emails and texts from sources.
We do not yet know whether the Libra approval is a signal of a thaw inside the Trump administration. The Interior Department’s freeze on renewables permitting decisions continues mostly unabated, and I have seen nothing to indicate that more decisions like this are coming down the pike. What we do know is that ahead of a difficult midterm election, the Trump administration faces outsized pressure to do more to address “affordability,” Democrats plan to go after Republicans for effectively repealing the Inflation Reduction Act and halting permits for solar and wind projects, and there’s a grand bargain to be made in Congress over permitting reform that rides on an end to the permitting freeze.
I anticipate that ahead of the election and further permitting talks in Congress, the Trump administration will mildly ease its chokehold on solar and wind permits because that is the most logical option in front of them. I do not think this will change the circumstances for more than a small handful of projects sited on federal lands that were already deep in the permitting process when Trump took power.
It’s impossible to conclude a conversation about next year’s project fights without ending on the theme that defined 2025: battery fire fears are ablaze, and they’ll only intensify as data centers demand excess energy storage capacity.
The January Moss Landing fire incident was a defining moment for an energy sector struggling to grapple with the effects of the Internet age. Despite bearing little resemblance to the litany of BESS proposals across the country, that one hunk of burning battery wreckage in California inspired countless communities nationwide to ban new battery storage outright.
There is no sign this trend will end any time soon. I expect data centers to only accelerate these concerns, as these facilities can also catch fire in ways that are challenging to address.
Plus a resolution for Vineyard Wind and more of the week’s big renewables fights.
1. Hopkins County, Texas – A Dallas-area data center fight pitting developer Vistra against Texas attorney general Ken Paxton has exploded into a full-blown political controversy as the power company now argues the project’s developer had an improper romance with a city official for the host community.
2. La Plata County, Colorado – This county has just voted to extend its moratorium on battery energy storage facilities over fire fears.
3. Dane County, Wisconsin – The city of Madison appears poised to ban data centers for at least a year.
4. Goodhue County, Minnesota – The Minnesota Center for Environmental Advocacy, a large environmentalist organization in the state, is suing to block a data center project in the small city of Pine Island.
5. Hall County, Georgia – A data center has been stopped down South, at least for now.
6. Dukes County, Massachusetts – The fight between Vineyard Wind and the town of Nantucket seems to be over.
