At least in the short term, developers looking to build quickly have just a few sites to choose from.
Donald Trump aims to spur the biggest nuclear development boom this side of the 21st century. The big question: Will it work?
Trump signed a fleet of executive orders on Friday seeking to quadruple U.S. nuclear capacity, expanding generation from 100 gigawatts today to 400 gigawatts by 2050. To that end, he also set a near-term goal to start construction on 10 new conventional reactors by 2030 — that is, within the next five years.
The interim goal on its own is, on its face, extremely ambitious. There have only been three reactors completed this century: Watts Bar Unit 2, which had a complicated, multi-decade development timeline and finally entered operation in 2016; and Vogtle Units 3 and 4, which started construction in 2009 and came online in 2023 and 2024, respectively.
Part of the reason those three facilities took so long is the convoluted permitting process nuclear hopefuls must navigate. (Chris Gadomski, lead nuclear analyst at BloombergNEF, called it a “gauntlet.”) It can take almost a decade for a new nuclear project to receive what’s called a “combined operating license” from the Nuclear Regulatory Commission, the federal body charged with overseeing civilian nuclear technology and power plant operations. The orders seek to simplify and accelerate the NRC’s licensing procedure, giving the body 18 months to issue new rules and guidance designed to shorten the timeline for processing new applications to 18 months at the longest, and to reduce the timeline for considering continuing operations licenses to just a year.
In the even nearer term, however, “If you want to build nuclear fast in this country, you would go to sites that are already licensed or already have infrastructure,” Brett Rampal, senior director of nuclear and power strategy at Veriten, told Heatmap. Many of these sites received NRC approval in the 2000 and 2010s but languished due to poor market conditions (the rise of cheap natural gas), the nuclear industry’s own instability (Westinghouse, a major contractor, went bankrupt in 2017), or some combination of both.
But even then the process is complicated, as Adam Stein, director of the nuclear energy innovation program of the Breakthrough Institute, told Heatmap. “Several of the sites with licenses for AP1000 [reactors] theoretically could start construction fairly quickly without major license changes,” he said. “However, that’s not likely to happen.”
The AP1000 is a 1-gigawatt pressurized water reactor made by Westinghouse, and it’s currently pumping out electrons at the Vogtle site in Georgia. There are hopes that it can become a standard design that is built over and over again at scale.
But even on an already-licensed site, any new project would be starting from scratch with its supply chain and workforce. And just because the site has a license now doesn’t mean its developers are done with the licensing process. “The licenses for those sites were issued for a design that was essentially what Vogtle started out as,” Stein explained. Vogtle subsequently underwent almost 200 license amendments, and it’s probable that a new build would want to incorporate many of these design changes into their license, as well. “That takes time,” Stein said.
Duke Energy, which serves over 8 million customers largely in the Southeast, has an active combined operating license for AP1000s in South Carolina. The company told South Carolina utilities regulators in April that its W.S. Lee site in the state “offers the best opportunity to deploy large light-water reactors in the Carolinas” — but that, at least at the time, “the conceptual deployment timeline from when a definitive “go forward” decision is made is about 13 to 14 years.” (Emphasis mine.)
The spokesperson noted that the combined operating license at the site “gives us optionality in the future to construct and operate two Westinghouse AP1000 units at the site,” and that “we will have an opportunity to update state Commissions in the Carolinas on our progress regarding the potential for future new nuclear investments later this year.” The spokesperson gave no specific indication that the company’s timeline for building a new plant had changed due to the executive orders.
Duke also terminated a combined operating license for a Florida site in 2018. “We currently have no nuclear planned for Duke Energy Florida per our 10-year site plan, although advanced nuclear overall is still a longer-term option,” the spokesperson said.
What about “advanced nuclear”? Several advanced nuclear projects have either applied for or gotten construction permits. Kairos Power received construction permits for demonstration reactors, while X-Energy, the Tennessee Valley Authority, and TerraPower have applied for construction permits for advanced reactors. These companies are pursuing a different pathway than the combined operating license application process and will need to apply for operation licenses as well. Two advanced reactor designs by NuScale have received approval from the NRC to date, including one that’s fresh as of Thursday, but there are no current plans to deploy either anywhere.
That hasn’t dampened excitement about advanced nuclear, including on sites with licenses for larger reactors. Virginia utility Dominion Energy is looking at new nuclear development at its North Anna site, which is licensed for a GE-Hitachi Economic Simplified Boiling Water Reactor, a large reactor which has received an NRC design certification but has not yet been deployed. But instead of conventional reactors, Dominion has a memorandum of understanding with Amazon to explore small modular reactor development.
Duke Energy, meanwhile, told Heatmap that the company “strongly supports the advancement and deployment of new nuclear technologies, including large reactors and small modular reactors, to meet the growing energy needs of our customers.”
There is one nuclear company that greeted the executive orders with fulsome excitement: The Nuclear Company. Unlike other newer entrants in the space, The Nuclear Company — which raised a $51 million Series A in April — aims to build six conventional reactors with “proven, licensed technology.”
“I feel like I’m Jack and Rose from the Titanic and my arms are out. I feel like we're flying finally,” Juliann Edwards, chief development officer at The Nuclear Company, told Heatmap. “I feel like we’ve been unleashed through these executive orders.”
As difficult and costly as it was to bring the new Vogtle reactors online, the process jumpstarted the previously dormant domestic nuclear industry. And The Nuclear Company thinks it would be a shame for this emergent expertise to go to waste.
The Nuclear Company has identified the first site where it plans to build, but it’s not yet public, Edwards told Heatmap, though she pointed to states such as Florida, South Carolina, North Carolina, Tennessee, and Alabama as places where the company could “hit the ground running,” given that they already have the necessary licenses in place.
And yet The Nuclear Company does not, itself, intend to design or operate these reactors. Instead it would run licensing, permitting, and construction, while also potentially serving as the facility’s long-term owner, depending on the regulatory structure of the local utilities and grid operators.
That still leaves the question of whether the market will end up valuing the power produced from all these new reactors at a level that will keep an operator in business. That’s not a given. In the 2010s, nuclear capacity fell in part because the market preferred natural gas to nuclear, since it was cheaper and could respond quickly to varying demand. “Why would you build a nuclear reactor when you got very cheap natural gas?” BNEF’s Gadomski, told Heatmap.
But the prospects of an artificial-intelligence-fueled data center boom, as well as the broader electrification of the economy, has begun to change this calculus, as utilities look to catch up to quickly rising electricity demand for the first time this century.
"I’m hoping that this environment doesn’t create too much uncertainty for folks, and I’m hoping it sends signals to get things going and that things will hopefully work out,” Rampal said. “I love my utilities, but they are 14 times bitten, 97 times shy.”
Editor’s note: This story has been updated to reflect that Duke Energy terminated its Florida license.

The company, Nuclearn, aims to speed development and licensing processes with the help of a specially trained large language model.
You’d be hard-pressed to dream up a buzzier clean tech concept than an AI platform custom-designed for the nuclear industry. Yet Phoenix-based startup Nuclearn has been betting on the role of artificial intelligence in the booming nuclear sector since 2021 — predating the wide launch of ChatGPT and the Trump administration’s recent embrace of nuclear energy.
Now the funds are rolling in. The company announced today that it raised a $10.5 million Series A round led by the climate tech venture fund Blue Bear Capital. With this cash, Nuclearn plans to expand its repertoire of AI offerings, which spans everything from identifying and documenting faults in a reactor to project scheduling, engineering evaluations, and licensing and permitting for new or modified reactors.
To expedite these processes, the company has developed its own, nuclear-specific language model, built atop existing open source models and trained on public data from the Nuclear Regulatory Commission and other government agencies, Nuclearn’s cofounder and CFO, Jerrold Vincent, told me. This allows the model to pick up on “a lot of nuclear specifics, whether it’s the acronyms, vernacular, specific processes, even just sometimes the way [the nuclear industry] thinks about certain types of issues and the level of scrutiny they put on one thing versus another,” he explained.
By way of example, Vincent told me that one of the startup’s current customers is working on a licensing application and wanted to conduct some background research to identify potential gaps or areas where the NRC might raise additional questions. Every other time the company has pre-checked an application like this, Vincent said, it was a 400-hour process. Nuclearn helped reduce that timeline to less than a day.
It’s a deeply resonant win for Vincent and his cofounder, Bradley Fox, who are all too familiar with the inefficiencies of the industry themselves. Prior to founding Nuclearn, both worked in data science at the Palo Verde Nuclear Generating Station in Arizona, where employees spent thousands of hours every year on “a lot of documentation, a lot of paperwork, a lot of manual work,” Vincent told me.
Natural language processing had some very obvious applications for the nuclear industry. “Everything in nuclear is text. Everything’s written down,” Vincent said. So when some of the seminal research on novel deep learning models started coming out in 2017 and 2018, Vincent and Fox took note, exploring ways they could apply this to their own work. “Those were trends we jumped on very, very early, not because they were particularly fashionable at the time or because there was a lot of hype around it, but because that was the type of techniques we needed to be able to solve these problems,” Vincent told me. “That’s why we got into the language model space half a decade before ChatGPT.”
For the majority of jobs, such as working on permitting or license renewals, Nuclearn uses a software layer on top of its language model to coordinate various AI agents working on tasks linked to different data sets, such as analyzing design functions, safety protocols, or systems degradation over time. The software then integrates these various outputs to generate reports or summary analyses. On the operational side, the company has its own benchmarks to evaluate how its AI tools are performing on nuclear-specific tasks.
To date, the company has integrated its AI platform into the operations of more than 65 reactors both domestically and abroad, which Vincent told me represents a mix of standard commercial reactors and small modular reactors. As the market heats up, demand may well follow. With the Trump administration pushing to accelerate nuclear development, electricity demand rising, and tech giants prioritizing clean, firm power, it’s boom times for companies looking to build everything from conventional nuclear plants to small modular reactors, microreactors, and the long-elusive fusion reactor, each and every one of which will have to be licensed and permitted.
All this activity also means that the nuclear workforce is under strain, especially given that 25% set to retire in the coming decade. “We’ve had knowledge and workforce challenges for several years now, and now it’s getting exacerbated quite substantially from all the macro trends going on,” Vincent told me. Given this situation, he doesn’t anticipate that the adoption of AI tools will necessarily lead to layoffs. These days, he said, the industry is just wondering “how do we do the things we need to do to operate a nuclear power plant safely and efficiently with less people?”
With this new capital, the startup plans to scale its operations to encompass even more aspects of nuclear reactor management. One future use case Vincent anticipates is helping to automate the sourcing of unique, industry-specific parts. There are plants operating today, he told me, that rely on equipment from vendors that may be long out of business. Figuring out how and where to source equivalent components is the type of niche challenge he’s excited to take on.
“It just tends to be very manual, labor intensive, and very documentation heavy,” Vincent told me of the industry as a whole. Luckily, “those are all things that AI is very good at solving these days.”

China's clean-energy investments are paying green dividends. Ember
China’s clean energy boom is bringing a global decline in fossil fuel demand into sight amid declines in usage in the buildings, vehicles, and industries of the world’s second-largest economy, according to the think tank Ember’s latest China Energy Transition Review. The report, released Tuesday morning, found that exports of solar panels, batteries, electric vehicles, and heat pumps are soaring, particularly to emerging economies, making the possibility of developing nations making possible an “energy leapfrog” over the coal phase of growth. From 2015 to 2023, China’s end consumption of fossil fuels fell 1.7% across buildings, industry and transport, while electricity use as a replacement rose by 65%. In power generation, fossil output dropped 2% in the first half of 2025 compared to the same period last year, as wind and solar generation soared by 16% and 43%, respectively. Last year alone, Beijing invested $625 billion in clean energy, 31% of the global total.
“China is now the main engine of the global clean energy transition,” Muyi Yang, coordinating lead author of Ember’s 2025 analysis, said in a statement. “Policy and investment decisions made in China over the last two decades are fundamentally changing the basis of China’s own energy system, and enabling other countries to also move swiftly from fossil to clean.”
As Americans scramble to buy electric vehicles ahead of the expiration of the $7,500 consumer tax credit at the end of this month, fewer of those cars are Teslas. The preliminary August data Cox Automotive released on Monday showed the best month for EVs in U.S. history was the worst for Tesla ever recorded. EVs climbed to almost 10% of total car sales last month, but Tesla’s share fell to 38%, with 55,000 cars sold all month. That’s up just 3% compared to July and down 6% from the year prior, while the company’s total market share fell from just over 40% in July and 45% in the first half of the year. By contrast, Heatmap’s Matthew Zeitlin noted, Tesla commanded about 80% of U.S. EV sales in 2020.
Also on Tuesday, the company unveiled two new energy storage products that could boost its utility division. At the RE+ conference in Las Vegas, Tesla presented the Megapack 3, the latest generation of its utility-scale battery system, and the Megablock, which integrates the Megapack 3 with transformers and switchgear. Batteries were Tesla’s fastest growing business in the first quarter of this year, as Matthew reported in April, but the company feared that tariffs would affect the business. “The energy segment — which includes the company’s battery energy storage businesses for residences (Powerwall) and for utility-scale generation (Megapack) — has recently been a bright spot for the company, even as its car sales have leveled off and declined.”
Google inked a deal with the Salt River Project, the utility serving much of Arizona’s largest metropolis, to test the performance of long-duration energy storage projects. The first-of-a-kind research collaboration aims to “better understand the real-world performance of emerging non-lithium ion long duration energy storage technologies” in the Phoenix area, the power company said in a press release. Google will fund a portion of the costs and evaluate data on the pilot projects’ operational success. “We believe that long duration energy storage will play an essential role in meeting SRP’s sustainability goals and ensuring grid reliability,” Chico Hunter, the nonprofit Salt River Project’s manager of innovation and development, said in a statement.
As I reported in this newsletter in July, Google also backed the Italian carbon dioxide-based storage startup Energy Dome as the tech giant pushes to expand its portfolio of technologies to power its data centers 24/7.
The European Union has been a solid backer of fusion energy research. But the anti-nuclear trifecta of Germany, Austria, and Luxembourg has long thwarted bloc-wide efforts to bolster fission, which provides the bulk of the continent’s electricity. With Berlin finally joining Paris in backing traditional nuclear power, that blockade is no longer holding. The European Commission has proposed spending $11.5 billion on bolstering research in both fusion and fission, the trade publication NucNet reported Monday.
Meanwhile in the United States, where nuclear power remains broadly supported across the political spectrum, the biggest question is how quickly new reactors can come online. The data center industry has now called on the Nuclear Regulatory Commission to streamline licensing of new reactors to help meet its surging demand for electricity. In a letter to NRC Chair David Wright shared with E&E News, the Data Center Coalition, a trade group representing server farms, urged the agency to update its regulations to ensure quicker deployment of advanced reactors. “Increasingly, DCC members are forming strategic partnerships and committing to offtake agreements with utilities and nuclear technology developers, injecting new momentum into this strategic sector,” wrote Cy McNeill, the group’s director of federal affairs. “We are approaching the cusp of a truly revitalized nuclear sector.”
The push comes amid what Heatmap’s Katie Brigham called a “nuclear power dealmaking boom.”
Patagonia’s billionaire founder helped popularize the greenest trend in apparel — buying less of higher quality, longer-lasting clothing. Now the retailer is pushing to bring that same ethos to the food business. The company’s edible offerings of tinned fish and crackers designed for hiking is now expanding into baby foods, oils, and sauces, The New York Times reported in a new profile of the retailer. Fifty years from now, founder Yvon Chouinard told the newsletter, “I could see the food business being bigger than the apparel business.”
U.S. EV sales have been way up — just not for the domestic champion, which sank to its worst-ever market share in August.
Americans are rushing to buy electric vehicles ahead of the expiration of the $7,500 consumer tax credit at the end of this month.
And fewer of those cars are Teslas.
Preliminary data from Cox Automotive for August, first shared with Reuters, shows that the month was the best for EVs in U.S. history, with just over 146,000 units sold, comprising almost 10% of total car sales that month. At the same time, Tesla’s share of the EV market hit its lowest recorded level, down to a (still sizable) 38%.
Cox’s data puts Tesla sales at 55,000 for the month, which is up a little more than 3% from July but down over 6% from a year prior, while the company’s total market share fell from just over 40% in July and 45% in the first half of the year. In 2020, by contrast, Tesla’s share of U.S. EV sales was about 80%. Overall, Cox estimated that Tesla sales in the U.S. are down about 9% so far this year.
“The U.S. EV market is in a far more dynamic place than a few years ago,” Corey Cantor, the research director at the Zero Emission Transportation Association, told me in an email. “Most automakers now offer electric vehicle models in multiple segments. There are multiple electric vehicles available below the average price point of a new car at $48,000.”
Entering this new phase means that the EV market is getting less Tesla-centric, almost by definition. Morgan Stanley reported that electric vehicle sales were up 23% in August from a year ago, while overall car sales were up 7.5% — although even amidst this industry-wide growth, Tesla sales fell more than 3% year over year, while electric vehicle sales were up 42%.
Much of that EV market growth comes down to timing. “Early indications are that EV sales are in fact surging over the past two months, following the changes that will phase the credit out at the end of this month. We’ve seen record sales for EV models last month, such as the Honda Prologue,” Cantor said. This likely means some portion of these sales are being “pulled forward” from buyers trying to beat the deadline and these sales numbers will not persist through the rest of the year.
As Tesla’s stranglehold over the U.S. EV market may be weakening, so too is its hold on the international market. Thanks to CEO Elon Musk’s association with right wing politics in the U.S. and abroad, and to fierce competition from Chinese EV leader BYD, Tesla’s sales have fallen dramatically in Europe. Globally, BYD overtook Tesla in sales last year.
None of that seems to matter much to Tesla’s leadership, or to its shareholders. On Friday, the company’s board of directors put forward a new compensation plan for Musk that would boost his ownership of the company to around 25% and put him in line for a $1 trillion payday if he meets growth and performance targets over the next decade.
A Delaware court last year threw out an earlier Musk pay package, arguing that Musk was too close to the board of directors for them to objectively determine his pay in the interest of all the company’s shareholders. (He subsequently relocated Tesla’s official headquarters to Austin, Texas, explicitly to avoid Delaware jurisdiction.) Musk has said that he wants to own about 25% of the company, a significant upgrade from the roughly 15% he owns currently.
Tesla’s board said in a recent regulatory disclosure that Musk had “reiterated that, if he were to remain at Tesla, it was a critical consideration that he have at least a 25% voting interest in Tesla,” and that “Mr. Musk also raised the possibility that he may pursue other interests that may afford him greater influence if he did not receive such assurances.”
The board’s disclosure also confirmed that Musk sees the future of Tesla as going far beyond selling cars to people. The filing said that “through its discussions with Mr. Musk,” the special committee in charge of coming up with his compensation had “identified four core product lines that would drive Tesla’s future transformation”: Tesla’s vehicle fleet, automation (i.e. Full Self-Driving) software, its robotaxi product, and humanoid robots. Tesla’s robotaxi service is available on a select basis in Austin, with no date yet indicated for a wider rollout, while its humanoid robots — which Musk has said will one day make up 80% of the company’s value — are due to reach “scale production” next year, Musk said on a recent earnings call.
Tesla stock actually rose on the news of the proposed compensation package, likely because Tesla shareholders viewed it as a way to retain Musk and keep his attention on the company.
Longtime Tesla bull Adam Jonas, an analyst at Morgan Stanley, said in note to investors that the compensation deal now means that Musk “has an incentive to focus on Tesla more than ever.” Jonas also, like many Tesla bulls, sees its business of selling cars to people as just a small portion of its overall value — in his case, $76 a share, compared to his $410 a share price target or the roughly $346 a share price the stock was trading at on Monday afternoon.
Still, the company today is largely a pretty normal car company, at least according to its income statement. In the second quarter of its current fiscal year, some $16.6 billion of Tesla’s $22.5 billion in revenue came from cars, with $2.8 billion coming from its energy business and $3 billion coming from “services and other revenues.”
Declining market share in its biggest product line isn’t completely meaningless, even if many Tesla shareholders see a glorious future for the company beyond the automobile trade.
Looking ahead, Cantor said to expect the EV market to get even more diverse.
“Moving forward, we will continue to see automakers innovate in the EV space. Timelines may change and models will vary by automaker, but high-profile launches expected over the next year include the Rivian R2, a new version of the Chevrolet Bolt EV, as well as more affordable models by Lucid and Kia,” Cantor said in his email.
“While the 30D [consumer electric vehicle tax] credit’s phase out will have a real impact on sales the next quarter or two here in the U.S.,” he added, “the long-term trend of excitement and innovation continues to be in the launch of new electric vehicles.”
