“Old economy” companies like Caterpillar and Williams are cashing in by selling smaller, less-efficient turbines to impatient developers.

From the perspective of the stock market, you’re either in the AI business or you’re not. If you build the large language models pushing out the frontiers of artificial intelligence, investors love it. If you rent out the chips the large language models train on, investors love it. If you supply the servers that go in the data centers that power the large language models, investors love it. And, of course, if you design the chips themselves, investors love it.
But companies far from the software and semiconductor industry are profiting from this boom as well. One example that’s caught the market’s fancy is Caterpillar, better known for its scale-defying mining and construction equipment, which has become a “secular winner” in the AI boom, writes Bloomberg’s Joe Weisenthal.
Typically construction businesses do well when the overall economy is doing well — that is, they don’t typically take off with a major technological shift like AI. Now, however, Caterpillar has joined the ranks of the “picks and shovels” businesses capitalizing on the AI boom thanks to its gas turbine business, which is helping power OpenAI’s Stargate data center project in Abilene, Texas.
Just one link up the chain is another classic “old economy” business: Williams Companies, the natural gas infrastructure company that controls or has an interest in over 33,000 miles of pipeline and has been around in some form or another since the early 20th century.
Gas pipeline companies are not supposed to be particularly exciting, either. They build large-scale infrastructure. Their ratemaking is overseen by federal regulators. They pay dividends. The last gas pipeline company that got really into digital technology, well, uh, it was Enron.
But Williams’ shares are up around 28% in the past year — more than Caterpillar. That’s in part, due to its investing billions in powering data centers with behind the meter natural gas.
Last week, Williams announced that it would funnel over $3 billion into two data center projects, bringing its total investments in powering AI to $5 billion. This latest bet, the company said, is “to continue to deliver speed-to-market solutions in grid-constrained markets.”
If we stipulate that the turbines made by Caterpillar are powering the AI boom in a way analogous to the chips designed by Nvidia or AMD and fabricated by TSMC, then Williams, by developing behind the meter gas-fired power plants, is something more like a cloud computing provider or data center developer like CoreWeave, except that its facilities house gas turbines, not semiconductors.
The company has “seen the rapid emergence of the need for speed with respect to energy,” Williams Chief Executive Chad Zamarin said on an August earnings call.
And while Williams is not a traditional power plant developer or utility, it knows its way around natural gas. “We understand pipeline capacity,” Zamarin said on a May earnings call. “We obviously build a lot of pipeline and turbine facilities. And so, bringing all the different pieces together into a solution that is ready-made for a customer, I think, has been truly a differentiator.”
Williams is already behind the Socrates project for Meta in Ohio, described in a securities filing as a $1.6 billion project that will provide 400 megawatts of gas-fired power. That project has been “upsized” to $2 billion and 750 megawatts, according to Morgan Stanley analysts.
Meta CEO Mark Zuckerberg has said that “energy constraints” are a more pressing issue for artificial intelligence development than whether the marginal dollar invested is worth it. In other words, Zuckerberg expects to run out of energy before he runs out of projects that are worth pursuing.
That’s great news for anyone in the business of providing power to data centers quickly. The fact that developers seem to have found their answer in the Williamses and Caterpillars of the world, however, calls into question a key pillar of the renewable industry’s case for itself in a time of energy scarcity — that the fastest and cheapest way to get power for data centers is a mix of solar and batteries.
Just about every renewable developer or clean energy expert I’ve spoken to in the past year has pointed to renewables’ fast timeline and low cost to deploy compared to building new gas-fired, grid-scale generation as a reason why utilities and data centers should prefer them, even absent any concerns around greenhouse gas emissions.
“Renewables and battery storage are the lowest-cost form of power generation and capacity,” Next Era chief executive John Ketchum said on an April earnings call. “We can build these projects and get new electrons on the grid in 12 to 18 months.” Ketchum also said that the price of a gas-fired power plant had tripled, meanwhile lead times for turbines are stretching to the early 2030s.
The gas turbine shortage, however, is most severe for large turbines that are built into combined cycle systems for new power plants that serve the grid.
GE Vernova is discussing delivering turbines in 2029 and 2030. While one manufacturer of gas turbines, Mitsubishi Heavy Industries, has announced that it plans to expand its capacity, the industry overall remains capacity constrained.
But according to Morgan Stanley, Williams can set up behind the meter power plants in 18 months. xAI’s Colossus data center in Memphis, which was initially powered by on-site gas turbines, went from signing a lease to training a large language model in about six months.
These behind the meter plants often rely on cheaper, smaller, simple cycle turbines, which generate electricity just from the burning of natural gas, compared to combined cycle systems, which use the waste heat from the gas turbines to run steam turbines and generate more energy. The GE Vernova 7HA combined cycle turbines that utility Duke Energy buys, for instance, range in output from 290 to 430 megawatts. The simple cycle turbines being placed in Ohio for the Meta data center range in output from about 14 megawatts to 23 megawatts.
Simple cycle turbines also tend to be less efficient than the large combined cycle system used for grid-scale natural gas, according to energy analysts at BloombergNEF. The BNEF analysts put the emissions difference at almost 1,400 pounds of carbon per megawatt-hour for the single turbines, compared to just over 800 pounds for combined cycle.
Overall, Williams is under contract to install 6 gigawatts of behind-the-meter power, to be completed by the first half of 2027, Morgan Stanley analysts write. By comparison, a joint venture between GE Vernova, the independent power producer NRG, and the construction company Kiewit to develop combined cycle gas-fired power plants has a timeline that could stretch into 2032.
The Williams projects will pencil out on their own, the company says, but they have an obvious auxiliary benefit: more demand for natural gas.
Williams’ former chief executive, Alan Armstrong, told investors in a May earnings call that he was “encouraged” by the “indirect business we are seeing on our gas transmission systems,” i.e. how increased natural gas consumption benefits the company’s traditional pipeline business.
Wall Street has duly rewarded Williams for its aggressive moves.
Morgan Stanley analysts boosted their price target for the stock from $70 to $83 after last week’s $3 billion announcement, saying in a note to clients that the company has “shifted from an underappreciated value (impaired terminal value of existing assets) to underappreciated growth (accelerating project pipeline) story.” Mizuho Securities also boosted its price target from $67 to $72, with analyst Gabriel Moreen telling clients that Williams “continues to raise the bar on the scope and potential benefits.”
But at the same time, Moreen notes, “the announcement also likely enhances some investor skepticism around WMB pushing further into direct power generation and, to a lesser extent, prioritizing growth (and growth capex) at the expense of near-term free cash flow and balance sheet.”
In other words, the pipeline business is just like everyone else — torn between prudence in a time of vertiginous economic shifts and wanting to go all-in on the AI boom.
Williams seems to have decided on the latter. “We will be a big beneficiary of the fast rising data center power load,” Armstrong said.

The former FERC chair explains why Chris Wright is likely to succeed where Rick Perry failed.
Neil Chatterjee thinks it’s going to go better this time.
Eight years ago, Chatterjee was the chairman of the Federal Energy Regulatory Commission, and Trump was the president. When Trump’s then-Secretary of Energy, Rick Perry, asked the commission to ensure that generators able to store fuel on site — which in the U.S. largely means coal and nuclear — get extra payments for doing so, thus keeping struggling power plants in business, it rejected the proposal by a unanimous vote.
“There’s no doubt my 2017 experience — that was politically driven,” Chatterjee told me, though he did concede that Perry was “right to be concerned about retiring generation at the time.” The Perry plan had been heavily influenced by the coal industry, he told me, and the regulatory structure of “compensating plants for having the attribute of on-site fuel … it was just a bit of a stretch.”
Now there’s a new Trump administration, with a new Secretary of Energy and a new FERC — and on Thursday, Energy Secretary Chris Wright asked the commission to do something else. He put forward what’s known as an advance notice of proposed rulemaking, directing FERC to come up with ways to help to make sure the grid can deal with another large-scale transition.
“They’re just apples and oranges,” Chatterjee said of the two requests. “This is a much more elegant, much more thoughtful exercise.”
Wright’s letter lays out the challenge of integrating large loads — i.e. data centers — onto the grid, arguing that they “must be able to connect to the transmission system in a timely, orderly, and non-discriminatory manner.” Doing so, he said, will “require unprecedented and extraordinary quantities of electricity and substantial investment in the Nation’s interstate transmission system.”
The overall thrust of the proposal is to make things easier and faster, including suggesting that interconnection studies for large loads that have their own generation or are flexible could be finished in just 60 days — which, if successful, could take a process that can last for years and get it done in less than a season.
The notice suggests a number of reforms for FERC to consider, including faster interconnection for “large loads that agree to be curtailable and hybrid facilities that agree to be curtailable and dispatchable” — touching on what has been the hottest subject in energy policy this year.
Tyler Norris, a Duke University researcher who has been one of the leading promoters of load flexibility, called Wright’s notice a “BFD” — that is, big effing deal — in a brief email to Heatmap.
Norris elaborated further on X. The proposal “appears to have done the near-impossible — generate overwhelming bipartisan enthusiasm — in what may be the most positive cross-sector response we’ve seen yet to DOE action under Secretary Wright,” he wrote.
Wright’s proposal suggests that both new data centers and new sources of power should be studied together for interconnection. While this sounds like it would be adding complexity, it may actually be simplifying the process. “Such an approach will allow for efficient siting of loads and generating facilities and thereby minimize the need for costly network upgrades,” the proposal says, reflecting the twinned desire to get more data centers on line faster while shielding electricity consumers from higher costs.
Another of Wright’s suggestions, however, might face more opposition. He argues that “load and hybrid facilities should be responsible for 100% of the network upgrades that they are assigned through the interconnection studies.”
This is designed to address the possibility — already being realized in parts of the country — that the network infrastructure required to bring data centers online could lead to higher costs for all electricity customers served by a given utility as it spreads out those costs to its rate base. The risk, however, is that utilities won’t like it. That’s because in most of the country, utilities earn a regulated rate of return on their investment in grid upgrades (by way of customer bill payments, of course), creating an incentive for them to continue to spend.
Those dynamics may be changing. Utilities once enjoyed primacy in Washington on electricity policy, especially among Republicans, but have seen their status slip of late in favor of a new force: big tech companies with big data centers.
“The hyperscalers have the influence to counteract the utilities here,” Chatterjee told me. “And that’s a new dynamic, historically — when it came to FERC, when it came to DOE, when it came to, quite frankly, Congress. People are sensitive to their utilities.”
Wright’s proposal, Chatterjee said, is trying to balance several different considerations the White House faces.
“This is the most vexing issue before the commission right now. And the reality is, it’s not clean politically within FERC, within DOE, even within the White House. There are differences of opinion on how best to thread this needle,” he told me, pointing to divides between those who want to drive AI development as fast as possible and those who are concerned about electricity prices.
By contrast, the Perry proposal to FERC was widely recognized as being primarily about supporting the coal (and to some extent nuclear) industry.
“I really think what DOE has put forward here is kind of an elegant solution that touches on everything,” Chatterjee said. “It’s not preferring particular sources of generation. It’s for flexibility — flexibility is having its moment.”
The proposal has already won some plaudits from the technology industry. In a letter to the White House, OpenAI Chief Global Affairs Officer Christopher Lehane wrote that the company “welcomed the news last week that DOE recommended to FERC that it assert jurisdiction and create standardized rules for large load interconnections.” He also noted that OpenAI’s data centers “are designed to be curtailable — reducing their draw or even returning power during peak demand, helping to protect reliability and avoid higher costs for consumers.”
The DOE gave FERC an April 2026 deadline for final action on the proposed rulemaking, and FERC said Monday night that comments would be due by November 14.
Chatterjee said he expects FERC to eventually issue rules based on the proposal on a unanimous and bipartisan basis.
“I think the initial thought was, Oh, here goes the Trump administration again, leaning on FERC. This is actually a thoughtful exercise that I think most people in the energy space recognize is necessary to be done.”
On global emissions, Bill Gates on Chinese nuclear, and a geothermal breakthrough
Current conditions: Hurricane Melissa made landfall over Jamaica as one of the strongest Category 5 storms on record before barreling north toward Cuba • A cold front will send temperatures plunging as far as 15 degrees below average across the mid-Atlantic and the Northeast • The Colombian Andes are bracing for flooding amid up to 8 inches of rain forecast for Wednesday.

The Trump administration’s all-of-government approach to thwarting construction of offshore wind turbines has included the Department of the Interior de-designating federal waters to turbine development and the Department of Transportation yanking funding, in addition to various steps taken by other agencies. Now the Department of Health and Human Services is taking its swing at the industry. On Tuesday, Bloomberg reported that Secretary of Health and Human Services Robert F. Kennedy, Jr. directed the Centers for Disease Control and Prevention to open an investigation into the potential harms offshore wind farms pose. In late summer, the agency instructed the CDC’s National Institute for Occupational Safety and Health to prepare research about wind farms’ impact on fishing businesses. The effort included Kennedy personally meeting with NIOSH director Josh Howard, in the course of which he gave Howard — a career physician and lawyer who previously oversaw federal efforts on September 11 victims’ health — specific experts to contact, according to the newswire report. The U.S. Surgeon General’s office has also been involved in the initiative.
It’s part of what Heatmap’s Jael Holzman called “Trump’s total war on wind,” an assault that started on President Donald Trump’s first day back in office. Earlier this month, oil major Shell’s top executive in the United States warned that the precedents the administration was setting risked being weaponized against fossil fuel companies once Trump exited power.
In the first real decline ever forecast by the United Nations, global emissions are now expected to fall by 10% below 1990 levels by 2035, according to a report issued Tuesday. But the world remains far off from the 60% reduction goal scientists say is necessary to keep warming below 1.5 degrees Celsius, the target leaders committed to when they signed the Paris Agreement a decade ago. “Humanity is now clearly bending the emissions curve downwards for the first time, although still not nearly fast enough,” Simon Stiell, executive secretary at the UN Framework Convention on Climate Change, told Bloomberg on Tuesday. “We have a serious need for more speed.”
The latest assessment comes as the U.S. is withdrawing from the Paris climate negotiations and other countries are paring back spending on decarbonization ahead of the UN climate talks in Belem, Brazil, next month.
On Tuesday, Bill Gates released a provocative new treatise on climate change in which he laid out what he sees as necessary ahead of November’s climate summit. Before that, on Friday afternoon, the billionaire philanthropist gathered with half a dozen journalists in a conference room in Manhattan to discuss his latest ideas over lunch. Heatmap’s Robinson Meyer, who was in attendance, has a good breakdown of some of what Gates discussed. I also attended the lunch and wanted to highlight another point Gates made: The West is losing the race for new nuclear power. When it comes to fission, China is building more reactors than anyone else, and helped perfect the Westinghouse AP1000 before its successful construction in the U.S. Gates’ own reactor developer, TerraPower, had plans to build its debut plant in China prior to the souring in relations between Washington and Beijing nearly a decade ago. When it comes to fusion, he said, there’s no topping how much funding China has directed toward the technology.
“The amount of money they’re putting into fusion is more than the rest of the world put together, times two,” Gates told us. “There is a substantial amount of Chinese capital going into that, and in fission, they built the most reactors.”
Chemical giant Honeywell has announced a new technology that converts agricultural and forestry waste into ready-to-use renewable fuels that can directly replace the carbon-intensive fuel used by large ships and airplanes. The so-called “Biocrude Upgrading” processing hardware can be provided in modular form and equipped to ships at a moment when global regulators are seeking to slash the roughly 3% of planet-heating emissions that come from cargo vessels. “The maritime industry has a real need for renewable fuels that are immediately available and cost effective,” Ken West, Honeywell’s energy and sustainability solutions president, said in a statement. The news comes nearly two weeks after Trump “torpedoed” — as Heatmap’s Katie Brigham put it — efforts at the International Maritime Organization to slash emissions from regulated ships.
The geothermal startup Eavor said Tuesday that its breakthroughs in drilling had slashed the time it takes to drill its wells underground. The Canadian company said that the results of two years of drilling at its flagship project in Geretsried, Germany, showed its efforts to dig to hotter and deeper locations are working. “Much like wind and solar have come down the cost curve, much like unconventional shale [oil and gas] have come down the cost curve, we now have a technical proof-point that we’ve done that in Europe,” Jeanine Vany, a cofounder and executive vice president of corporate affairs at Eavor, told Canary Media’s Maria Gallucci.
The breakup of the ancient supercontinent 1.5 billion years ago transformed the Earth’s surface environments and laid the groundwork for the emergence of complex life. That’s according to new research by Australian scientists at the University of Sydney and the University of Adelaide. The findings challenge what has long been called the “boring billion,” a time when biological and geological changes effectively stalled. The plate tectonics that reshaped the planet triggered conditions that supported oxygen-rich oceans and fostered the appearance of the first eukaryotes, the ancestors of all complex life. “Our work reveals that deep Earth processes, specifically the breakup of the ancient supercontinent Nuna, set off a chain of events that reduced volcanic carbon dioxide emissions and expanded the shallow marine habitats where early eukaryotes evolved,” Dietmar Müller, a University of Sydney professor and the study’s lead author, said in a press release.
Rob talks New Jersey past, present, and future with Employ America’s Skanda Amarnath.
Electricity prices are the biggest economic issue in the New Jersey governor’s race, which is perhaps next month’s most closely watched election. Mikie Sherrill, the Democratic candidate and frontrunner, has pledged to freeze power prices for state residents after getting elected. Can she do that?
On this week’s episode of Shift Key, Rob talks to Skanda Amarnath, the executive director of Employ America, a center-left think tank that aims to encourage a “full-employment, robust-growth economy.” He’s also a nearly lifelong NJ resident. They chat about how New Jersey got such expensive electricity, whether the nuclear construction boom is real, and what lessons nuclear companies should take from economic history.
Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University. Jesse is off this week.

Here is an excerpt from our conversation:
Robinson Meyer: Is there a nuclear bubble? … As people who are interested in long-term decarbonization, number one, this is quite reminiscent of the environment that hit clean energy companies right as Biden was taking office. And number two, is there a nuclear bubble, and what does this mean for how we should think about nuclear going forward? Because at the end of this, I think the only way that any of this helps the climate is if we build a lot more plants.
Skanda Amarnath: We are definitely in a moment when there’s a lot of froth. I don’t want to say everything — it’s always like, it’ll feel unfair and not accurate to go after every single proposition that’s in markets. Like for example, Rick Perry’s Fermi America, they did an IPO and raised a lot of capital pretty successfully. And they have a plan for how they want to build a lot of stuff out — gas, solar, batteries. They want to build four AP1000s, the large, light-water reactors that are seen as the most recent that we’ve built in the United States, and they think they could do them at the same speed that China builds those same reactors.
On the surface of it, there are parts of it that seem interesting and promising. On the other hand, there’s also parts of it that feel very much wrapped up in the speculative frenzy. It gets more exaggerated when you get to like examples like Oklo. They seem to be very politically connected, specifically to Chris Wright. That plus some very small milestone successes in the fuel supply chain are now being sort of magnified into, They’re going be very successful in building out there first of a kind technology. And even in the space of small modular reactors, what they’re offering seems at least substantially more risky than what may be — outside of the space, so even compared to GE’s proposition for a small boiling water reactor, the technology that’s involved with like Oklo is kind of out there.
And one of the things, the lessons of nuclear, if you look through the history, is the more new stuff you’re doing, the harder it is, the more likely it is that you will get heartburn in terms of cost, in terms of schedule, and you never want to do this again. And it’ll involve a lot of bankruptcy, as it did with the case of the Georgia reactors that were built in the last decade. And so this is a sign that there’s clearly a lot of hype and a lot of willingness to take risk, and it’s not really backed up by fundamentals. That can be sometimes overrated in a boom. But that is something that people will look to in a bust and say, what were we doing here? Why was the price of the stock so high?
