It took a lot of scrutiny and a lot of patience, but the city council is finally making progress against natural gas infrastructure.

Susan Albright, a city councilor in Newton, Massachusetts, was reviewing the latest batch of requests from the local gas utility in early July when one submission caught her off guard. The company, National Grid, regularly asks the city for permission to tear up stretches of road in order to replace aging gas mains and service lines. But this time, the utility wanted to install a new 46-foot pipeline leading to Newton Crossing, a mixed-use housing development that’s currently under construction.
“I thought, Oh my god,” Albright told me. “Here we are trying to get rid of pipe, and here’s some new pipe that they’re asking for.”
Such “grant of location” requests used to be a rubber stamp exercise for the Public Facilities Committee, of which Albright is the chair. But more recently, they’ve become contentious. Activists have started showing up to public meetings to question the necessity of pipeline work. Could the pipes be repaired instead of replaced? Or even better, retired? Could the houses served by them be electrified?
To get ahead of public outcry about a brand new pipe, Albright sprung into action. She pulled up plans the housing developer had filed with the city and learned that the apartments were intended to be all-electric. The developer had requested a gas connection solely to serve commercial businesses on the ground level. Albright found a contact for the project and picked up the phone.
“Is there any possibility that you could go electric for your commercial?” she recalled asking, explaining the connection between natural gas and climate change, and the city’s goal of weaning off gas. “At first he was very reluctant,” she told me. “But then he called me back and said that he’s willing to try it.” His ability to do so will depend on whether the electric utility can supply enough power. Nonetheless, Albright had successfully pushed a vote on the request to a later date. “We will review that grant of location at our meeting on July 28, and hopefully he will withdraw it, but we don’t know,” she said.
The city committed to transitioning away from natural gas by 2050 as part of its Climate Action Plan, enacted in 2019. Although residents have started to electrify their homes, the city hasn’t been able to slow down investment into the gas system. The story of Newton Crossing illustrates a strategy that has finally begun to move the needle. Councilors and activists have begun doggedly scrutinizing each of National Grid’s requests in hopes of finding alternatives that avoid investing more ratepayer money into a gas system that is — or should be — on a path toward obsolescence.
Progress has not been linear, and almost all of these attempts have so far failed. But the city does seem to have gotten the company’s attention. Earlier, in June, National Grid came to Newton with a different kind of request — an invitation to embark on a collaboration together with the local electric utility, Eversource, to proactively plan the city’s transition away from gas, and in doing so, begin to create a model for the company, the state, and possibly the country.
“I’m so excited to be here today because this is the first of its kind,” Bill Foley, National Grid’s director of strategy and transformation told the Public Facilities Committee while presenting the proposal. “We’ve never sat down with Eversource, National Grid, and another community to talk about how we’re going to broadly electrify a community.”
The subterranean network of natural gas pipes that runs under Massachusetts is old and leaky, with some sections dating back to the late 19th century. Utilities in the Commonwealth have always been required to address dangerous leaks, but in 2014, the state passed a law incentivizing more proactive measures to replace or repair leak-prone pipes. It was a matter of public safety as well as environmental protection — the methane that seeps out can kill tree roots in addition to being a powerful greenhouse gas.
The law created the Gas System Enhancement Program, or GSEP. Each fall, companies would file annual plans to the Department of Public Utilities outlining all the pipeline repair and replacement projects they aimed to complete in the coming year. In return, they’d get quicker approvals from regulators and be able to recover the costs more quickly from ratepayers.
In the years since, utilities have spent billions of dollars replacing thousands of miles of pipelines. Simultaneously, the state has fleshed out its plans to tackle climate change, making it clear that electrifying buildings would be a key component. As a result, the tide of public opinion about the pipeline program shifted. Replacing aging pipes may actually be worse for the climate, many activists now believe, since it means putting major investments in new fossil fuel infrastructure, thereby increasing inertia in the energy system and possibly delaying the transition to carbon-free solutions.
Former mechanical engineer Peter Barrer is one of those activists. Barrer lives in Newton, and has become an expert on the local gas network and the state’s pipeline policies. Using public data filed with state regulators, he calculated that out of the $18 million National Grid spent to address aging pipes under the GSEP program in Newton in 2023, only about $200,000 went to repairs, with the rest going to replacements. (National Grid later disputed the number, reporting that it spent $3 million on repairs that year.)
Barrer is concerned that the GSEP gives the company cover to spend excessively on pipeline replacements, which earn them larger profits than repairs. Other analysts have reached similar conclusions. Last year, the energy research consultancy the Brattle Group submitted testimony to state regulators on behalf of the Massachusetts attorney general’s office arguing that utilities are increasingly using GSEP to make everyday capital improvements. The level of spending “goes far beyond remediating immediate risks to safety caused by gas leaks,” the consultants wrote.
Barrer’s research on GSEP led him to a potential point of leverage with National Grid. When the utility wants to dig up a street, it has to submit a Grant of Location request to Newton’s Public Facilities Committee, which is then subject to a public hearing.
Newton is a progressive city that has long been at the forefront of climate action in the state. It’s one of 10 communities granted permission by the state to ban gas hookups in new buildings. (The Newton Crossing development got its permits before the policy went into effect.) The city council has also passed an ordinance requiring the largest existing buildings to reduce their emissions to net-zero by 2050.
While the Public Facilities Committee doesn’t have the power to deny National Grid’s Grant of Location requests, Albright, the city councilor, told me, the meetings do present an opportunity to engage with the utility. Members and the public can ask questions and delay approvals. Barrer and other activists began using the requests as an opportunity to highlight the paradox of the city approving new gas infrastructure.
One particularly contentious fight began last October over a replacement on Garland Road, a street known for hosting a “Sustainable Street Tour,” during which residents spoke about their experiences greening their homes with solar, insulation, EVs, and heat pumps. “Bells kind of rang in my mind,” Barrer told me. “Here’s a great place to fight National Grid.”
The gas company argued that the Garland Road pipeline, 600 feet of cast iron from the 1920s, was simply too high-risk. “National Grid cannot agree to delay replacement long enough to determine if the Garland Rd customers that still use their gas service for one or more uses are willing to have their gas service disconnected,” Amy Smith, the director of the company’s New England Gas Business Unit, wrote in an email to Albright in January. “In addition, even if all customers on Garland Rd agree to have their gas service cut off, we do not currently have a mechanism to fund the costs of full electrification of each home.” The Committee signed off on the project.
But activists continued to challenge it. A resident of Garland Road, Jon Slote, surveyed his neighbors and found that all were either neutral or supportive of electrification. He also put together a cost comparison and found that the capital cost of electrifying the homes was 18% to 41% lower than that of replacing the pipeline.
National Grid didn’t budge. One of the reasons the block couldn’t be electrified, Smith explained to Barrer in emails that I reviewed, was that this segment of pipe “plays a critical role in providing pressure support for approximately 120 homes in the area. Maintaining minimum pressure is vital for both safety and reliability.”
Barrer told me he’s skeptical that replacing the pipe is the only solution, but acknowledged that the issue is real.
Perhaps Barrer’s biggest grievance, though, is that National Grid frequently makes requests that are not in its regulator-approved plans. Nearly 60% of the money the company spent in 2023 and was able to recover through the expedited GSEP process went to such projects, he found. A related issue: GSEP plans often don’t disclose the full extent of each project. “This is important for municipal planning,” Barrer told me. If the public can’t see in advance which areas the company is planning to work on, he said, “there’s no opportunity for the city to investigate. Maybe there’s streets on there that we can get support for electrification.”
He described the fight over gas pipelines in Newton as “a David and Goliath situation.” Activists want the opportunity to get ahead of these projects and figure out alternatives, he said, but aren’t given enough notice or details. “They have all the cards. They have a monopoly on gas, and they also have a monopoly on information.” He wants the state legislature to help them put up a fairer fight by passing two new bills that would require the utilities to disclose more information, sooner.
Albright, meanwhile, told me she thinks National Grid has acted in good faith. “The people that I’ve been working with, I trust that they’re trying to do the best for the company and for us as customers. I mean, they don’t want these pipes to explode.”
For about a year, Albright said, she has been having conversations with Smith of National Grid about what the city could do to start getting off gas. At the end of 2024, Smith came back with an offer — National Grid would work with Newton on an electrification pilot project. The company has since provided the city with a list of streets to consider for the pilot — mostly dead ends on the outskirts of the gas system, areas where taking out a stretch of pipe won’t affect other customers downstream.
Meanwhile, a lot has changed at the state level. Late last year and continuing into this spring, lawmakers and regulators enacted new policies to reform GSEP and better align it with the Commonwealth’s clean energy plans. That meant focusing on the highest risk pipes, prioritizing repairs instead of replacements, lowering the cap on spending for companies, and enabling them to spend some of the money on alternatives to pipelines, including electrification projects.
Perhaps these changes help explain what led National Grid to approach Newton earlier this summer with its proposal to collaborate. At the Public Facilities Committee’s June 18 meeting, representatives from National Grid and Eversource spent nearly three hours explaining their “integrated energy planning” effort, figuring out how to transition from gas to electricity while containing costs and ensuring reliable service. Now they wanted the chance to begin testing it out in a community.
“The technical stuff is easy,” Foley of National Grid told the Committee. “When it comes to knocking on a door and saying, Hey, how do we get you to electrify? That’s the challenging part. That’s what we’re going to learn.”
The Committee, the mayor, and city staff welcomed the idea. Even Barrer is optimistic. “I think it is unprecedented,” he told me, “and it could be very, very useful.” But he’s also skeptical. Will the company actually share the information advocates like him are looking for to analyze alternatives? And will it work quickly?
“From my perspective, every year that the plan doesn’t turn into action is another half a billion dollars of ratepayer money the National Grid gets to invest.” But, he added, “I’m hopeful. Let’s see what actually develops.”

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