According to a new analysis shared exclusively with Heatmap, coal’s equipment-related outage rate is about twice as high as wind’s.

The Trump administration wants “beautiful clean coal” to return to its place of pride on the electric grid because, it says, wind and solar are just too unreliable. “If we want to keep the lights on and prevent blackouts from happening, then we need to keep our coal plants running. Affordable, reliable and secure energy sources are common sense,” Energy Secretary Chris Wright said on X in July, in what has become a steady drumbeat from the administration that has sought to subsidize coal and put a regulatory straitjacket around solar and (especially) wind.
This has meant real money spent in support of existing coal plants. The administration’s emergency order to keep Michigan’s J.H. Campbell coal plant open (“to secure grid reliability”), for example, has cost ratepayers served by Michigan utility Consumers Energy some $80 million all on its own.
But … how reliable is coal, actually? According to an analysis by the Environmental Defense Fund of data from the North American Electric Reliability Corporation, a nonprofit that oversees reliability standards for the grid, coal has the highest “equipment-related outage rate” — essentially, the percentage of time a generator isn’t working because of some kind of mechanical or other issue related to its physical structure — among coal, hydropower, natural gas, nuclear, and wind. Coal’s outage rate was over 12%. Wind’s was about 6.6%.
“When EDF’s team isolated just equipment-related outages, wind energy proved far more reliable than coal, which had the highest outage rate of any source NERC tracks,” EDF told me in an emailed statement.
Coal’s reliability has, in fact, been decreasing, Oliver Chapman, a research analyst at EDF, told me.
NERC has attributed this falling reliability to the changing role of coal in the energy system. Reliability “negatively correlates most strongly to capacity factor,” or how often the plant is running compared to its peak capacity. The data also “aligns with industry statements indicating that reduced investment in maintenance and abnormal cycling that are being adopted primarily in response to rapid changes in the resource mix are negatively impacting baseload coal unit performance.” In other words, coal is struggling to keep up with its changing role in the energy system. That’s due not just to the growth of solar and wind energy, which are inherently (but predictably) variable, but also to natural gas’s increasing prominence on the grid.
“When coal plants are having to be a bit more varied in their generation, we're seeing that wear and tear of those plants is increasing,” Chapman said. “The assumption is that that's only going to go up in future years.”
The issue for any plan to revitalize the coal industry, Chapman told me, is that the forces driving coal into this secondary role — namely the economics of running aging plants compared to natural gas and renewables — do not seem likely to reverse themselves any time soon.
Coal has been “sort of continuously pushed a bit more to the sidelines by renewables and natural gas being cheaper sources for utilities to generate their power. This increased marginalization is going to continue to lead to greater wear and tear on these plants,” Chapman said.
But with electricity demand increasing across the country, coal is being forced into a role that it might not be able to easily — or affordably — play, all while leading to more emissions of sulfur dioxide, nitrogen oxide, particulate matter, mercury, and, of course, carbon dioxide.
The coal system has been beset by a number of high-profile outages recently, including at the largest new coal plant in the country, Sandy Creek in Texas, which could be offline until early 2027, according to the Texas energy market ERCOT and the Institute for Energy Economics and Financial Analysis.
In at least one case, coal’s reliability issues were cited as a reason to keep another coal generating unit open past its planned retirement date.
Last month, Colorado Representative Will Hurd, a Republican, wrote a letter to the Department of Energy asking for emergency action to keep Unit 2 of the Comanche coal plant in Pueblo, Colorado open past its scheduled retirement at the end of his year. Hurd cited “mechanical and regulatory constraints” for the larger Unit 3 as a justification for keeping Unit 2 open, to fill in the generation gap left by the larger unit. In a filing by Xcel and several Colorado state energy officials also requesting delaying the retirement of Unit 2, they disclosed that the larger Unit 3 “experienced an unplanned outage and is offline through at least June 2026.”
Reliability issues aside, high electricity demand may turn into short-term profits at all levels of the coal industry, from the miners to the power plants.
At the same time the Trump administration is pushing coal plants to stay open past their scheduled retirement, the Energy Information Administration is forecasting that natural gas prices will continue to rise, which could lead to increased use of coal for electricity generation. The EIA forecasts that the 2025 average price of natural gas for power plants will rise 37% from 2024 levels.
Analysts at S&P Global Commodity Insights project “a continued rebound in thermal coal consumption throughout 2026 as thermal coal prices remain competitive with short-term natural gas prices encouraging gas-to-coal switching,” S&P coal analyst Wendy Schallom told me in an email.
“Stronger power demand, rising natural gas prices, delayed coal retirements, stockpiles trending lower, and strong thermal coal exports are vital to U.S. coal revival in 2025 and 2026.”
And we’re all going to be paying the price.

Federal energy regulators directed the country’s largest grid to make its rules make sense.
Federal energy regulators don’t want utilities and electricity market rules getting in the way of data centers connecting directly to power plants.
That was the consensus message from both Republican and Democratic commissioners on the Federal Energy Regulatory Commission Thursday, when it issued its long-awaited order on co-location in PJM Interconnection, the country’s largest electricity market, covering the Mid-Atlantic and Midwest.
The question is a holdover from last year, when Amazon struck a deal with independent power producer Talen Energy to co-locate an Amazon Web Services data center with the Susquehanna nuclear plant in Pennsylvania. Amazon eventually amended the deal to a more traditional power purchase agreement after failing to win regulatory approval for a behind-the-meter arrangement. Constellation, which owns a number of nuclear power plants in the PJM territory, had asked FERC to force PJM to adopt co-location rules and prevent what it saw as utilities obstructing co-location projects.
More broadly, though, the dispute is between independent power plants and their owners and utilities who build and operate the transmission grid. The latter want the former to essentially pay full freight for grid services for co-located power plants, even if they are largely or exclusively serving a single customer — such as, let’s say, a data center. Even co-located loads still incur substantial grid costs, utilities have argued, which should be paid for in their entirety.
Co-location has become attractive lately as a way to get data centers online faster and limit expensive grid upgrades that could drive up costs for everyone on the grid. Up until now, though, PJM didn’t really have a way to determine the distribution of costs and responsibilities when some or all of a new demand source is served by a co-located generator — and it wasn’t really in a particular rush to set one up, FERC said.
“The Commission finds that PJM’s tariff does not appear to sufficiently address the rates, terms and conditions of service that apply to co-location arrangements,” FERC said in its order. “The absence of this information may leave generators and load unable to determine what steps they can take to set up co-location arrangements of various configurations, and how to do so in an acceptable way.”
The commission was unanimous in its order, showing that despite the increased partisanship of regulatory politics in Donald Trump’s Washington, FERC is still operating under its traditional consensus-based approach. The consensus also shows the high level of dissatisfaction across the political spectrum with rising electricity prices, and specifically with PJM, which has combined rising prices with a clogged interconnection process and concerns about reliability.
“If a new large load wants to connect directly with a power plant and operate in a way that lowers grid costs, we should let it. If the current rules don’t let this work in a way that’s fair for everyone,” said Commissioner David Rosner, a Democrat. “We should change those rules so we can deliver the savings that consumers need and ensure reliable electricity for everybody.”
In its order, the commission asked PJM to come up with new arrangements that will allow transmission costs to scale with actual usage of the transmission system.
To do so, the new rules will have to reflect the actual usage of the transmission system of a co-located data center or other large load, Rosner explained.
He gave the example of a 1,000-megawatt data center co-located with a new 900-megawatt power plant. Its draw from the grid would be 100 megawatts, but “under PJM status quo rules,” Rosner said, “the data center needs to take the full 1,000 megawatts of front-of-meter transmission service from the grid, despite being directly connected to the co-located power plant.”
With the new options FERC is mandating PJM come up with, “the data center will now have the option to purchase what we call firm contract demand to take just 100 megawatts of firm service,” Rosner said, which will help cut costs across the board, he added.
The order also touches on the other hottest subject in grid policy today: flexibility. Because PJM will no longer be required to plan transmission or assure it has capacity for directly-connected loads, Rosner said, a big customer will have to accept the risk of being curtailed “if its usage exceeds what it’s contracted for in advance.”
The renewables industry cheered the order, especially the message that PJM needs to embrace flexibility and enable new generation and load to get online quickly.
“PJM needs to heed FERC’s message that grid flexibility enables speed, affordability, and reliability. As PJM proposes new rules to enable fast-tracking large load interconnections, it should prioritize the advanced energy technologies that are quickest to build and enable flexibility,” Jon Gordon, policy director at Advanced Energy United, said in a statement.
Independent power producers — i.e. the companies that own that power plants — also seemed happy with what the commission had to say. Talen, Constellation Energy, and Vistra Energy, all of whom have substantial footprints in PJM, saw their share prices rise at least 3% in early Thursday trading.
Thursday’s order comes as “large load interconnection” — i.e. data centers hooking up to the grid — dominates the energy regulatory discussion. Secretary of Energy Chris Wright has asked FERC to come up with new rules early next year to speed up interconnection without jacking up consumer electricity prices. At the same time, PJM’s market is under stress, with another capacity auction this week resulting in yet another round of record-setting payments to generators — plus, this time, a failure to secure its typical margin over and above its minimum projected capacity needed to ensure future reliability.
PJM is working on its own new set of rules to connect large loads without large price impacts, a process that has so far resulted in not much, as the market’s board has yet to agree on a proposal to bring to FERC.
Beating up on PJM was a bipartisan affair Thursday morning.
“The order recognizes that PJM existing transmission services are insufficient in that they do not recognize the controllable nature of co-location arrangement’s,” the commission’s Republican Chair Laura Swett said in her statement at Thursday’s meeting.
“Flexible options for co-located load means carving a path for minimizing expensive and time-intensive network upgrades in circumstances where they’re not needed,” Commissioner Lindsay See, another Republican appointee, said.
Rosner’s statement echoed his colleagues’, arguing that the existing PJM rates and contracts are “unjust and unreasonable” because they do not “contain provisions addressing with sufficient clarity or consistency the rates, terms and conditions of service that apply to interconnection customers serving co-located load and eligible customers taking transmission service on behalf of co-located load.”
He also addressed the electricity market’s board directly: “In my opinion, PJM board, tomorrow, once you’ve read this order, would be a great day to file this with us,” Rosner said.

The Trump administration plans to dismantle the National Center for Atmospheric Research in Colorado. Founded in 1960, The New York Times credited the center with “many of the biggest scientific advances in humanity’s understanding of weather and climate.” But in a post on X late Tuesday evening, Russell Vought, the director of the White House’s Office of Management and Budget, called the institute “one of the largest sources of climate alarmism in the country,” and said the administration would be “breaking up” its operations. It’s just the latest attempt by the White House to salt the Earth for federal climate science. As I wrote in August, the administration went as far as rewriting existing climate reports.
The latest capacity auction in PJM Interconnection, where power generators in the nation’s largest electricity market bid to provide power when the grid is especially stressed, ended at the legally-mandated cap of $333.44 per megawatt. This adds up to some $16.4 billion, a record-setting figure following the past two auctions, which brought in $16.1 billion and $14.7 billion.
This auction covers 2027 through 2028, and is the last that will be subject to the price cap. Despite the dizzying spending, it failed to procure enough power to meet PJM’s preferred 20% reserve margin for a severe demand event. The auction procured 145,777 megawatts of capacity, 6,623 megawatts short of the target, giving the grid a 14.8% margin. Much of that projected demand will come from data centers, which, as Heatmap’s Matthew Zeitlin wrote, have stressed the grid operator nearly to the breaking point.

Global coal use is set to start declining over the next five years as renewables and liquified natural gas gobble up its market share, the International Energy Agency projected in its latest annual forecast Wednesday. Demand is on track to inch upward 0.5% this year to a record 8,845 million tons before dropping 3% by 2030. Analysts warned Bloomberg that coal has remained “stubbornly strong” given high levels of consumption in China and India, and the Paris-based IEA cautioned that its five-year outlook “is subject to significant uncertainties that could impact it materially.”
Among the factors that look increasingly certain: That the Trump administration won’t allow any more U.S. coal plants to shut down. On Tuesday, the Department of Energy ordered the 730-megawatt TransAlta Centralia Generation in Washington to remain past its retirement at the end of this month, despite the state’s ban on coal operations. There’s just one big problem with that plan, as Matthew wrote last month. Old coal plants keep breaking down.

Nuno Loureiro, a professor of nuclear science and the director of the Massachusetts Institute of Technology’s Plasma Science and Fusion Center, died Tuesday after being shot multiple times in his home near Boston the night before. Police statements made no mention of a suspect or motives, but Loureiro’s coveted position as one of the United States’ leading fusion scientists stoked speculation that the killing was politically motivated. Prominent influencers including the Trump adviser Laura Loomer falsely claimed that Loureiro, who was from Portugal, was Jewish and a vocal activist for the Israeli government. But The Jerusalem Post reported that Israeli intelligence officials are investigating potential links between the murder and the Iranian government, though the newspaper cautioned that the assessment “has not yet been verified.” As of now, there is no clear evidence of who killed Loureiro or why. His death shocked the field of research in which he was lauded as a leader. A former colleague in Portugal who started working at the same laboratory with Loureiro years ago in Lisbon and “knew him well” told me, “Everyone here is in shock.”
Back in June, Matthew wrote a good piece explaining why the commonly used metric known as levelized cost of energy was “wrong.” Essentially, LCOE represents the energy output of a given source in terms of its construction and operating expenses — the lower the LCOE, the more efficient it is operationally. But the metric fails to capture all the other things that make an energy source valuable, such as the frequency with which it operates, how long it lasts, or how much infrastructure is required to make use of it. When Ontario Power Generation assessed the cost of building new nuclear reactors at its Darlington station, the LCOE showed solar and batteries costing far less. But a full systems analysis found that nuclear reactors would last longer, require fewer transmission upgrades, and would not need back-up generation. A report published this morning by the consultancy FTI has proposed two new metrics instead: Levelized value of energy, or LVOE, “which reflects the total value a project can create for its owners, and Levelized Net Benefit (LNB), which quantifies the broader value a project can deliver to the overall system.” While the LCOE for solar is roughly 40% lower than nuclear power in both Texas’ ERCOT grid system and PJM, a chart from the report shows that nuclear has an LVOE roughly 10 times greater.

Record rainfall last month has revived an ancient lake in an unusual place. When ice covered the Sierra Nevada between 128,000 and 186,000 years ago, a lake 100 miles long and 600 feet deep sat in what is today the Mojave Desert in eastern California. That lake, called Lake Manly, has returned. As the science site Phys.org reported, “now Death Valley, one of the hottest places on Earth and the lowest point in North America, has a desert lake framed by snow-capped mountains.” But the “marvel” is likely to disappear soon.
With new corporate emissions restrictions looming, Japanese investors are betting on carbon removal.
It’s not a great time to be a direct air capture company in the U.S. During a year when the federal government stepped away from its climate commitments and cut incentives for climate tech and clean energy, investors largely backed away from capital-intensive projects with uncertain economics. And if there were ever an expensive technology without a clear path to profitability, it’s DAC.
But as the U.S. retrenches, Japanese corporations are leaning in. Heirloom’s $150 million Series B round late last year featured backing from Japan Airlines, as well as major Japanese conglomerates Mitsubishi Corporation and Mitsui & Co. Then this month, the startup received an additional infusion of cash from the Development Bank of Japan and the engineering company Chiyoda Corporation. Just days later, DAC project developer Deep Sky announced a strategic partnership with the large financial institution Sumitomo Mitsui Banking Corporation to help build out the country’s DAC market.
Experts told me these investments probably won’t lead to much large-scale DAC deployment within Japan, where the geology is poorly suited to carbon sequestration. Many of these corporations likely don’t even plan to purchase DAC-based carbon offsets anytime soon, as they haven’t made the type of bold clean energy commitments seen among U.S. tech giants, and cheaper forestry offsets still dominate the local market.
Rather, contrary to current sentiment in the U.S., many simply view it as a fantastic business opportunity. “This is actually a great investment opportunity for Japanese companies now that the U.S. companies are out,” Yuki Sekiguchi, founder of Startup Navigator for Climate Tech and the leader of a group for the Japanese clean tech community, told me. “They get to work with really high caliber startups. And now everybody’s going to Japan to raise money and have a partnership, so they have a lot to choose from.”
Chris Takigawa, a director at the Tokyo-based venture firm Global Brain, agreed. Previously he worked at Mitsubishi, where he pioneered research on CO2 removal technologies and led the company’s investment in Heirloom. “Ultimately, if there’s going to be a big project, we want to be part of that, to earn equity from that business,” he told me of Mitsubishi’s interest in DAC. “We own large stakes in mining assets or heavy industrial assets. We see this as the same thing.”
Takigawa said that he sees plenty of opportunities for the country to leverage its engineering and manufacturing expertise to play a leading role in the DAC industry’s value chain. Many Japanese companies have already gotten a jump.
To name just a few, NGK Insulators is researching ceramic materials for carbon capture, and semiconductor materials company Tokyo Ohka Kogyo is partnering with the Japanese DAC startup Carbon Xtract to develop and manufacture carbon capture membranes. The large conglomerate Sojitz is working with academic and energy partners to turn Carbon Xtract’s tech into a small-scale “direct air capture and utilization" system for buildings. And the industrial giant Kawasaki Heavy Industries has built a large DAC pilot plant in the port city of Kobe, as the company looks to store captured CO2 in concrete.
During his time at Mitsubishi, as he worked to establish the precursor to what would become the Japan CDR Coalition, Takigawa told me he reached out to “all the companies that I could think about that might be related to DAC.” Most of them, he found, were already either doing research or investing in the space.
Japan has clear climate targets — reach net-zero by 2050, with a 60% reduction in emissions by 2035, and a 73% reduction by 2040, compared to 2013 levels. It’s not among the most ambitious countries, nor is it among the least. But experts emphasize that its path is stable and linear.
“In Japan, policy is a little more top down,” Sekiguchi told me. Japan’s business landscape is dominated by large conglomerates and trading companies, which Sekigushi told me are “basically tasked by the government” to decarbonize. “And then you have to follow.”
Unlike in the U.S., climate change and decarbonization are not very politically charged issues in Japan. But at the same time, there’s little perceived need for engagement. A recent Ipsos poll showed that among the 32 countries surveyed, Japanese citizens expressed the least urgency to act on climate change. And yet, there’s broad agreement there that climate change is a big problem, as 81% of Japanese people surveyed said they’re worried about the impacts already being felt in the country.
The idea that large corporations are being instructed to lower their emissions over a decades-long timeframe is thus not a major point of contention. The same holds for Japan’s now-voluntary emissions trading scheme, called the GX-ETS, that was launched in 2023. This coming fiscal year, compliance will become mandatory, with large polluters receiving annual emissions allowances that they can trade if they’re above or below the cap.
International credits generated from DAC and other forms of carbon removal, such as bioenergy with carbon capture and storage, are accepted forms of emissions offsets during the voluntary phase, making Japan the first country to include engineered credits in its national trading scheme. But to the dismay of the country’s emergent carbon removal sector, it now appears that they won’t be included in the mandatory ETS, at least initially. While a statement from the Chairman and CEO of Japan’s Institute of Energy Economics says that “carbon removal will be recognized in the future as credits,” it’s unclear when that will be.
Sekiguchi told me this flip-flop served as a wake-up call, highlighting the need for greater organizing efforts around carbon removal in Japan.
“Now those big trading houses realize they need an actual lobbying entity. So they created the Japan CDR Coalition this summer,” she explained. Launched by Mitsubishi, the coalition’s plans include “new research and analysis on CDR, policy proposals, and training programs,” according to a press release. The group’s first meeting was this September, but when I reached out to learn more about their efforts, a representative told me the coalition had “not yet reached a stage where we can effectively share details or outcomes with media outlets.”
Sekiguchi did tell me that the group has quickly gained momentum, growing from just a handful of founding companies to a membership of around 70, including representatives from most major sectors such as shipping, chemicals, electronics, and heavy industry.
Many of these companies — especially those in difficult to decarbonize sectors — might be planning for a future in which durable engineered carbon offsets do play a critical role in complying with the country’s increasingly stringent ETS requirements. After all, Japan is small, mountainous, densely populated, and lacks the space for vast deployments of solar and wind resources, leaving it largely dependent on imported natural gas for its energy needs. “We’ll always be using fossil fuels,” Takigawa told me, “So in order to offset the emissions, the only way is to buy carbon removals.”
And while the offset market is currently dominated by inexpensive nature-based solutions, “you have to have an expectation that the price is going to go up,” Sekiguchi told me. The project developer Deep Sky is certainly betting on that. As the company’s CEO Alex Petre told me, “Specifically in Japan, due to the very strong culture of engineering and manufacturing, there is a really deep recognition that engineered credits are actually a solution that is not only exciting, but also one where there’s a lot of opportunity to optimize and to build and to deploy.”
As it stands now though, the rest of the world may expect a little too much of Japan’s nascent DAC industry, experts told me.
Take the DeCarbon Tokyo conference, which was held at the beginning of December. Petre, Sekiguchi, and Takigawa all attended. Petre’s takeaway? “Deep Sky is not the only company that has figured out that Japan is really interested in decarbonization,” she put it wryly. DAC companies Climeworks and AirMyne were also present, along with a wide range of other international carbon removal startups such as Charm Industrial, Captura, and Lithos Carbon.
Overall, Sekiguchi estimated that about 80% of the participants in the conference were international companies or stakeholders looking for Japanese investment, whereas “it should be the other way around” for a conference held in Tokyo.
“I think there’s big potential, Japan can be a really big player,” she told me. But perhaps Americans and Europeans are currently a little overzealous when it comes to courting Japanese investors and pinning their expectations on the country’s developing decarbonization framework. “There’s so much hope from the international side. But in Japan it’s still like, okay, we are learning, and we are going steadily but kind of slowly. So don’t overwhelm us.”
