Now back at the University of Pennsylvania, she talks to Heatmap about community engagement, gaps in the decarbonization market, and goats.
In November of 2020, Jennifer Wilcox had just moved to Philadelphia and was preparing to start a new chapter in her career as a tenured “Presidential Distinguished Professor” at the University of Pennsylvania. Then she got the call: Wilcox was asked to join the incoming Biden administration as the principal deputy assistant secretary for the Office of Fossil Energy, a division of the Department of Energy.
Wilcox had never even heard of the Office of Fossil Energy and was somewhat uneasy about the title. A chemical engineer by training, Wilcox had dedicated her work to climate solutions. She was widely known for having written the first textbook on carbon capture, published in 2012, and for her trailblazing research into removing carbon dioxide from the atmosphere. With Penn’s blessing, she decided to take the job. And in the just over three years she was in office, she may have altered the course of U.S. climate action forever.
First, Wilcox led a total transformation of the department to align it with the Biden administration’s climate goals. She started by arranging 15-minute meetings with each of the nearly 150 employees who worked with her at the D.C. office to understand their perspectives on their work, whether they were happy, and their fears and challenges. She admits she can be intense.
“I took all that information, and I sat on it with many weekends and a blank piece of paper and a pencil and drew crazy diagrams,” she told me, trying to funnel everyone’s feedback into a new vision for the department.
Previously, the Office of Fossil Energy’s primary function was to support research into oil, gas, and coal extraction and use. Wilcox flipped the mission on its head, reorganizing the department into one that would support research, development, and deployment of solutions that reduced dependency on those resources and minimized their environmental impacts. By July, she had codified that mission in a new name — the Office of Fossil Energy and Carbon Management.
Wilcox maxed out her leave this spring. I caught up with her about a week after she left the DOE, as she was picking up where she left off — preparing for her first semester as a professor of chemical engineering and energy policy at Penn. She’s also starting a new side gig as chief scientist at Isometric, a carbon credit certification company that’s trying to improve trust in carbon removal measurement and verification through rigorous standards and transparency.
I asked her to reflect on her time at the Department of Energy, the changes she oversaw, and what she’s looking to do next. Our conversation has been edited for length and clarity.
When was your last day at DOE? Did you leave because you had an obligation to come back to Penn?
My last day was Friday, May 31, so just a week or so ago. Typically, when you’re in an academic tenured position, you can have a maximum of a two-year leave. Within the first year of my appointment at DOE, the Bipartisan Infrastructure Law went through, and then in the second year, the IRA went through — the Inflation Reduction Act. And I was like, this is big stuff. It felt like just a defining moment — in my career, but also in terms of climate legislation. And I thought, how could I possibly leave now? So I went back to Penn and I wrote, I thought, a pretty thoughtful letter of the impact that I could have if I could stay just a year and a half longer. And they said yes.
Could you share the story of how you were asked to go work for the department in the first place?
Sure, it’s pretty funny. Something that many people don’t know is we have a small farm — we had 22 acres in Massachusetts, and goats and a pig and chickens and oh my goodness. Penn was like, “We’ll move your goats, too,” and so we moved everybody. And here I am at the kitchen table amidst boxes, and the goats are outside, and I’m on my laptop, and I get this email from the Biden-Harris transition team. I was like, ain’t nobody got time for that. That’s spam. Delete! And then a couple days go by and I get another one, and I was like, come on. Is this real? And I forwarded it to my husband. He’s an ER doctor, and he’s like, “Honey, that’s real. You have to respond!” And so I sent my CV.
One of the first things you did was rename the department. How did that happen?
When I came in, it was really early days of, okay, net zero by 2050, and there was a question of, what does that mean for our office? Should this office exist in a net zero world?I knew that I was being recruited to think about reshaping, rethinking the portfolio.
We only had two R&D offices at the time. One was called Oil and Gas — we renamed that Office of Resource Sustainability. The other was literally the Office of Coal. What I decided to do was take that program and move it over. That whole office is all about, if you’re choosing to extract energy resources from the Earth, how do you do it in a way that’s minimal impact?
Now, what’s left is how you manage the pollution of how we use fossil fuels — that’s the carbon dioxide. And so we built out a whole new division on carbon removal. We teased out a whole program on hydrogen, and then we also separated out carbon conversion into its own division, and then carbon transport and storage. And so rather than one program focused on carbon, we had five, which is pretty cool. I mean, the amount that I was empowered and supported — and by the way, we got it all through without a single pushback, in nine months. So that was huge.
How would you characterize how the field changed from the time that you entered the office until now? Have research questions changed? Have policy priorities changed?
I think things are starting to change. One of the things from these last few years of having the resources that have started to become mobilized, it’s helping us to recognize where the gaps really are. When you have money to be able to put out for certain topic areas, you get to see who’s going to apply, and who applies gives you an indication of where the technology is at and how much of it’s ready.
For instance, if you look at the $3.5 billion for direct air capture hubs, we had to write the funding opportunity announcement to meet industry where they’re at. There’s only a couple of companies that are really even at a stage where they can start to think about demonstration on the tens of thousands of tons of removal, let alone a million tons per year.
Some of the gaps that we saw were, in direct air capture, making sure that there’s enough companies that are supported to be able to get us to the scale that we need to. And then for the other approaches to carbon removal, making sure that if we want these projects to be durable, in terms of carbon removed on a time scale that impacts climate, we need to figure out how to quantify the net carbon that’s removed.
And then one significant gap that we saw that we are trying to fill with this funding: When we think about corporations and net zero pledges, a lot of times the carbon removal purchasing is associated with Scope 3 emissions that companies don’t have the ability to control. These are supply chains. It could be paper, it could be fuel, food, glass, cement, steel. And so looking at that whole sector, it’s about 10 different industrial sectors that we need to figure out how to decarbonize. If we can think about decarbonizing these supply chains, it’ll take some of the pressure off of the carbon removals to counterbalance those.
The last piece that I feel like gets forgotten is, in the infrastructure law, we had $2.5 billion for building out geologic storage. That’s an issue because you can do the carbon capture, but the big question is, where are you going to put it? And can you get it from point A to point B? We have a whole program called CarbonSAFE that essentially shepherds the industry through the process, starting with characterization all the way to a class six permit from EPA. Building that capacity out means that’s one less thing that industry has to worry about as they’re looking at carbon capture.
During your time there, the department was interfacing with hundreds of researchers and startup founders who were all trying to get new projects or companies off the ground. I’m curious, what are some of the most common misunderstandings you saw from applicants?
There’s a couple of things, but one that stands out — and maybe this is because I have a background in academia — there’s a lot of technologies out there that are actually pretty far along, especially in point source capture [technologies that capture carbon from the smokestacks of industrial facilities before it enters the atmosphere]. Yet, at universities, they’re still trying to develop the next solvent or solid sorbent. It’s like, we can stop doing that.
Where the R&D comes in is actually getting data over a long period of time. How does the material behave? How can we recycle it and reuse it over and over again? How can we design it in a way that reduces NOx, SOx pollution, particulate matter, making the air cleaner? But it’s not about how do we just develop a new technology, because there’s a lot out there.
It seems like one of the hardest things the department was trying to do under your leadership was to strengthen its work on community engagement and community benefits — hard because many advocates for fenceline communities are so skeptical of the solutions you were working on. How did you navigate that tension?
Well, one thing is, I know what I don’t know, and I’m usually pretty willing to say what I’m good at and what I’m not good at. In the early days, I knew that this was going to be a challenge for our office and so I recruited a social scientist: Holly Jean Buck, she’s a professor at the University of Buffalo. We brought Holly in to help us develop some of the language around … it started off with community benefits, but some of our investments don’t always lead to benefits, so let’s be honest, right? And so what we wanted to think about is, what are the societal considerations and impacts of our investments? We ended up recruiting a few others, and now we have a team that’s focused on domestic engagement, and also communications and outreach.
What do you think it could mean for some of what you’ve accomplished and other things you’ve set in motion if Biden is not reelected?
I feel pretty good about what we’ve put in place, that it’s sustainable. The other thing about what I saw is that industry is really leaning in on doing these things. The low-carbon supply chains — a lot of glassmakers, cement facilities — are very interested in improving energy efficiency, are interested in carbon capture or using hydrogen as a heat source. And so what we have done is really looking at making sure they’re economic. All of these efforts that we’ve put in place are extremely bipartisan, and they’re essentially just supporting industry in a way such that they’re achievable because they’re economic.
Let’s talk a little bit about what’s next. Why did you want to work with Isometric? What are you going to be doing there?
When I was at DOE, from the beginning, we were looking at, you know, there’s a lot of the carbon removal portfolio where we don’t have the rigor in place to be able to determine the durability of the removals, the additionality of them, the time scale on which the carbon is actually removed, quantifying net removed. And so we started a commercialization effort, leveraging our national labs to help us to develop the framework. Isometric is working toward establishing rigorous frameworks, and I’m hoping to leverage the efforts ongoing at DOE — and with transparency, so that others may follow, which could lead to more durable removals and greater impact at the end of the day.
What about on the academic side of your career. Where do you plan to focus your research?
Some of the work that we were doing, or the team has been continuing to do while I’m at DOE, is mineralization, looking at different waste feedstocks that have alkalinity [a property that’s useful for carbon removal], like magnesium and calcium. One of the things that we’re going to focus a little bit more on is asking the question of, what else is there? You know, if there’s rare earth elements or critical minerals that could be used for clean energy technologies, EV motors, magnets for wind turbines. And so, I’m really excited about looking at these materials and seeing what value is there.
I’m also really excited about helping with the measurement and quantification of some of the more natural systems of removal, like forests. One of the new majors at Penn is artificial intelligence. I think there’s an opportunity right now to think about, how can we take data, whether it’s from drones or whether it’s from Lidar and airplanes or satellite data, bringing it together in an integrated way again, so that we have more robust databases that are also transparent.
There’s so many debates going on around carbon removal right now, and it feels like they often come down to philosophical differences. Are these debates important? Or do we just need to decide what we’re going to do and then reevaluate it later?
We’re not in a position anymore to think we can just decarbonize and not do greenhouse gas removals. We know we need to do both. And so I think that there are some kind of “no regrets” things that we can do — opportunities, as we’re scaling up both in the near term, to think about them in a coordinated way. In communities that don’t have solar today, imagine you have a direct air capture facility going in, and then they’re bringing clean energy that they’re using for direct air capture, but they’re bringing it for the first time ever to a community that wouldn’t otherwise have access.
But it really is regional. I think it’s regional in that there’s limited resources in any given region, whether it’s low-carbon energy, land, clean water, even geologic pore space. You have it in some states and not others. And so we really need to look at those resources and always prioritize decarbonizing, but recognize that it’s not necessarily one or the other.

Ecolectro, a maker of electrolyzers, has a new manufacturing deal with Re:Build.
By all outward appearances, the green hydrogen industry is in a state of arrested development. The hype cycle of project announcements stemming from Biden-era policies crashed after those policies took too long to implement. A number of high profile clean hydrogen projects have fallen apart since the start of the year, and deep uncertainty remains about whether the Trump administration will go to bat for the industry or further cripple it.
The picture may not be as bleak as it seems, however. On Wednesday, the green hydrogen startup Ecolectro, which has been quietly developing its technology for more than a decade, came out with a new plan to bring the tech to market. The company announced a partnership with Re:Build Manufacturing, a sort of manufacturing incubator that helps startups optimize their products for U.S. fabrication, to build their first units, design their assembly lines, and eventually begin producing at a commercial scale in a Re:Build-owned factory.
“It is a lot for a startup to create a massive manufacturing facility that’s going to cost hundreds of millions of dollars when they’re pre-revenue,” Jon Gordon, Ecolectro’s chief commercial officer, told me. This contract manufacturing partnership with Re:Build is “massive,” he said, because it means Ecolectro doesn’t have to take on lots of debt to scale. (The companies did not disclose the size of the contract.)
The company expects to begin producing its first electrolyzer units — devices that split water into hydrogen and oxygen using electricity — at Re:Build’s industrial design and fabrication site in Rochester, New York, later this year. If all goes well, it will move production to Re:Build’s high-volume manufacturing facility in New Kensington, Pennsylvania next year.
The number one obstacle to scaling up the production and use of cleaner hydrogen, which could help cut emissions from fertilizer, aviation, steelmaking, and other heavy industries, is the high cost of producing it. Under the Biden administration, Congress passed a suite of policies designed to kick-start the industry, including an $8 billion grant program and a lucrative new tax credit. But Biden only got a small fraction of the grant money out the door, and did not finalize the rules for claiming the tax credit until January. Now, the Trump administration is considering terminating its agreements with some of the grant recipients, and Republicans in Congress might change or kill the tax credit.
Since the start of the year, a $500 million fuel plant in upstate New York, a $400 million manufacturing facility in Michigan, and a $500 million green steel factory in Mississippi, have been cancelled or indefinitely delayed.
The outlook is particularly bad for hydrogen made from water and electricity, often called “green” hydrogen, according to a recent BloombergNEF analysis. Trump’s tariffs could increase the cost of green hydrogen by 14%, or $1 per kilogram, based on tariff announcements as of April 8. More than 70% of the clean hydrogen volumes coming online between now and 2030 are what’s known as “blue” hydrogen, made using natural gas, with carbon capture to eliminate climate pollution. “Blue hydrogen has more demand than green hydrogen, not just because it’s cheaper to produce, but also because there’s a lot less uncertainty around it,” BloombergNEF analyst Payal Kaur said during a presentation at the research firm’s recent summit in New York City. Blue hydrogen companies can take advantage of a tax credit for carbon capture, which Congress is much less likely to scrap than the hydrogen tax credit.
Gordon is intimately familiar with hydrogen’s cost impediments. He came to Ecolectro after four years as co-founder of Universal Hydrogen, a startup building hydrogen-powered planes that shut down last summer after burning through its cash and failing to raise more. By the end, Gordon had become a hydrogen skeptic, he told me. The company had customers interested in its planes, but clean hydrogen fuel was too expensive at $15 to $20 per kilogram. It needed to come in under $2.50 to compete with jet fuel. “Regional aviation customers weren’t going to spend 10 times the ticket price just to fly zero emissions,” he said. “It wasn’t clear to me, and I don’t think it was clear to our prospective investors, how the cost of hydrogen was going to be reduced.” Now, he’s convinced that Ecolectro’s new chemistry is the answer.
Ecolectro started in a lab at Cornell University, where its cofounder and chief science officer Kristina Hugar was doing her PhD research. Hugar developed a new material, a polymer “anion exchange membrane,” that had potential to significantly lower the cost of electrolyzers. Many of the companies making electrolyzers use designs that require expensive and supply-constrained metals like iridium and titanium. Hugar’s membrane makes it possible to use low-cost nickel and steel instead.
The company’s “stack,” the sandwich of an anode, membrane, and cathode that makes up the core of the electrolyzer, costs at least 50% less than the “proton exchange membrane” versions on the market today, according to Gordon. In lab tests, it has achieved more than 70% efficiency, meaning that more than 70% of the electrical energy going into the system is converted into usable chemical energy stored in hydrogen. The industry average is around 61%, according to the Department of Energy.
In addition to using cheaper materials, the company is focused on building electrolyzers that customers can install on-site to eliminate the cost of transporting the fuel. Its first customer was Liberty New York Gas, a natural gas company in Massena, New York, which installed a small, 10-kilowatt electrolyzer in a shipping container directly outside its office as part of a pilot project. Like many natural gas companies, Liberty is testing blending small amounts of hydrogen into its system — in this case, directly into the heating systems it uses in the office building — to evaluate it as an option for lowering emissions across its customer base. The equipment draws electricity from the local electric grid, which, in that region, mostly comes from low-cost hydroelectric power plants.
Taking into account the expected manufacturing cost for a commercial-scale electrolyzer, Ecolectro says that a project paying the same low price for water and power as Liberty would be able to produce hydrogen for less than $2.50 per kilogram — even without subsidies. Through its partnership with Re:Build, the company will produce electrolyzers in the 250- to 500-kilowatt range, as well as in the 1- to 5-megawatt range. It will be announcing a larger 250-kilowatt pilot project later this year, Gordon said.
All of this sounded promising, but what I really wanted to know is who Ecolectro thought its customers were going to be. Demand for clean hydrogen, or the lack thereof, is perhaps the biggest challenge the industry faces to scaling, after cost. Of the roughly 13 million to 15 million tons of clean hydrogen production announced to come online between now and 2030, companies only have offtake agreements for about 2.5 million tons, according to Kaur of BNEF. Most of those agreements are also non-binding, meaning they may not even happen.
Gordon tied companies’ struggle with offtake to their business models of building big, expensive, facilities in remote areas, meaning the hydrogen has to be transported long distances to customers. He said that when he was with Universal Hydrogen, he tried negotiating offtake agreements with some of these big projects, but they were asking customers to commit to 20-year contracts — and to figure out the delivery on their own.
“Right now, where we see the industry is that people want less hydrogen than that,” he said. “So we make it much easier for the customer to adopt by leasing them this unit. They don’t have to pay some enormous capex, and then it’s on site and it’s producing a fair amount of hydrogen for them to engage in pilot studies of blending, or refining, or whatever they’re going to use it for.”
He expects most of the demand to come from industrial customers that already use hydrogen, like fertilizer companies and refineries, that want to switch to a cleaner version of the fuel, or hydrogen-curious companies that want to experiment with blending it into their natural gas burners to reduce their emissions. Demand will also be geographically-limited to places like New York, Washington State, and Texas, that have low-cost electricity available, he said. “I think the opportunity is big, and it’s here, but only if you’re using a product like ours.”
On coal mines, Energy Star, and the EV tax credit
Current conditions: Storms continue to roll through North Texas today, where a home caught fire from a lightning strike earlier this week • Warm, dry days ahead may hinder hotshot crews’ attempts to contain the 1,500-acre Sawlog fire, burning about 40 miles west of Butte, Montana• Severe thunderstorms could move through Rome today on the first day of the papal conclave.
The International Energy Agency published its annual Global Methane Tracker report on Wednesday morning, finding that over 120 million tons of the potent greenhouse gas were emitted by oil, gas, and coal in 2024, close to the record high in 2019. In particular, the research found that coal mines were the second-largest energy sector methane emitter after oil, at 40 million tons — about equivalent to India’s annual carbon dioxide emissions. Abandoned coal mines alone emitted nearly 5 million tons of methane, more than abandoned oil and gas wells at 3 million tons.
“Coal, one of the biggest methane culprits, is still being ignored,” Sabina Assan, the methane analyst at the energy think tank Ember, said in a statement. “There are cost-effective technologies available today, so this is a low-hanging fruit of tackling methane.” Per the IEA report, about 70% of all annual methane emissions from the energy sector “could be avoided with existing technologies,” and “a significant share of abatement measures could pay for themselves within a year.” Around 35 million tons of total methane emissions from fossil fuels “could be avoided at no net cost, based on average energy prices in 2024,” the report goes on. Read the full findings here.

The Environmental Protection Agency told staff this week that the division that oversees the Energy Star efficiency certification program for home appliances will be eliminated as part of the Trump administration’s ongoing cuts and reorganization, The Washington Post reports. The Energy Star program, which was created under President George H.W. Bush, has, in the past three decades, helped Americans save more than $500 billion in energy costs by directing them to more efficient appliances, as well as prevented an estimated 4 billion metric tons of greenhouse gas from entering the atmosphere since 1992, according to the government’s numbers. Almost 90% of Americans recognize its blue logo on sight, per The New York Times.
President Trump, however, has taken a personal interest in what he believes are poorly performing shower heads, dishwashers, and other appliances (although, as we’ve fact-checked here at Heatmap, many of his opinions on the issue are outdated or misplaced). In a letter on Tuesday, a large coalition of industry groups including the Air-Conditioning, Heating, and Refrigeration Institute, the Association of Home Appliance Manufacturers, and the U.S. Chamber of Commerce wrote to EPA Administrator Lee Zeldin in defense of Energy Star, arguing it is “an example of an effective non-regulatory program and partnership between the government and the private sector. Eliminating it will not serve the American people.”
House Speaker Mike Johnson suggested that the electric vehicle tax credit may be on its last legs, according to an interview he gave Bloomberg on Tuesday. “I think there is a better chance we kill it than save it,” Johnson said. “But we’ll see how it comes out.” He estimated that House Republicans would reveal their plan for the tax credits later this week. Still, as Bloomberg notes, a potential hangup may be that “many EV factories have been built or are under construction in GOP districts.”
As we’ve covered at Heatmap, President Trump flirted with ending the $7,500 tax credit for EVs throughout his campaign, a move that would mark “a significant setback to the American auto industry’s attempts to make the transition to electric vehicles,” my colleague Robinson Meyer writes. That holds true for all EV makers, including Tesla, the world’s most valuable auto company. However, its CEO, Elon Musk — who holds an influential position within the government — has said he supports the end of the tax credit “because Tesla has more experience building EVs than any other company, [and] it would suffer least from the subsidy’s disappearance.”
Constellation Energy Corp. held its quarterly earnings call on Tuesday, announcing that its operating revenue rose more than 10% in the first three months of the year compared to 2024, beating expectations. Shares climbed 12% after the call, with Chief Executive Officer Joe Dominguez confirming that Constellation’s pending purchase of natural gas and geothermal energy firm Calpine is on track to be completed by the end of the year, and that the nuclear power utility is “working hard to meet the power needs of customers nationwide, including powering the new AI products that Americans increasingly are using in their daily lives and that businesses and government are using to provide better products and services.”
But as my colleague Matthew Zeitlin reported, Dominguez also threw some “lukewarm water on the most aggressive load growth projections,” telling investors that “it’s not hard to conclude that the headlines are inflated.” As Matthew points out, Dominguez also has some reason to downplay expectations, including that “there needs to be massive investment in new power plants,” which could affect the value of Constellation’s existing generation fleet.
The Rockefeller Foundation aims to phase out 60 coal-fired power plants by 2030 by using revenue from carbon credits to cover the costs of closures, the Financial Times reports. The team working on the initiative has identified 1,000 plants in developing countries that would be eligible for the program under its methodology.
Rob and Jesse go deep on the electricity machine.
Last week, more than 50 million people across mainland Spain and Portugal suffered a blackout that lasted more than 10 hours and shuttered stores, halted trains, and dealt more than $1 billion in economic damage. At least eight deaths have been attributed to the power outage.
Almost immediately, some commentators blamed the blackout on the large share of renewables on the Iberian peninsula’s power grid. Are they right? How does the number of big, heavy, spinning objects on the grid affect grid operators’ ability to keep the lights on?
On this week’s episode of Shift Key, Jesse and Rob dive into what may have caused the Iberian blackout — as well as how grid operators manage supply and demand, voltage and frequency, and renewables and thermal resources, and operate the continent-spanning machine that is the power grid. 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.

Here is an excerpt from our conversation:
Robinson Meyer: So a number of people started saying, oh, this was actually caused because there wasn’t enough inertia on the grid — that Spain kind of flew too close to the sun, let’s say, and had too many instantaneous resources that are metered by inverters and not by these large mechanical generators attached to its grid. Some issue happened and it wasn’t able to maintain the frequency of its grid as needed. How likely do you think that is?
Jesse Jenkins: So I don’t think it’s plausible as the precipitating event, the initial thing that started to drive the grid towards collapse. I would say it did contribute once the Iberian grid disconnected from France.
So let me break that down: When Spain and Portugal are connected to the rest of the continental European grid, there’s an enormous amount of inertia in that system because it doesn’t actually matter what’s going on just in Spain. They’re connected to this continen- scale grid, and so as the frequency drops there, it drops a little bit in France, and it drops a little bit in Latvia and all the generators across Europe are contributing to that balance. So there was a surplus of inertia across Europe at the time.
Once the system in Iberia disconnected from France, though, now it’s operating on its own as an actual island, and there it has very little inertia because the system operator only scheduled a couple thousand megawatts of conventional thermal units of gas power plants and nuclear. And so it had a very high penetration on the peninsula of non-inertia-based resources like solar and wind. And so whatever is happening up to that point, once the grid disconnected, it certainly lacked enough inertia to recover at that point from the kind of cascading events. But it doesn’t seem like a lack of inertia contributed to the initial precipitating event.
Something — we don’t know what yet — caused two generators to simultaneously disconnect. And we know that we’ve observed oscillation in the frequency, meaning something happened to disturb the frequency in Spain before all this happened. And we don’t know exactly what that disturbance was.
There could have been a lot of different things. It could have been a sudden surge of wind or solar generation. That’s possible. It could have been something going wrong with the control system that manages the automatic response to changes in frequency — they were measuring the wrong thing, and they started to speed up or slow down, or something went wrong. That happened in the past, in the case of a generator in Florida that turned on and tried to synchronize with the grid and got its controls wrong, and that causes caused oscillations of the frequency that propagated all through the Eastern Interconnection — as far away as North Dakota, which is like 2,000 miles away, you know? So these things happen. Sometimes thermal generators screw up.
