MIDDLETOWN, Pa. — The owner of the Three Mile Island nuclear power plant is embarking on an ambitious plan to restart operations before the end of the decade, marking the latest chapter in the history of a plant that symbolizes the future promise, past struggles and lingering fears of nuclear energy in the United States.
The twin cooling towers that stretch hundreds of feet above the Susquehanna River just south of Middletown, Pennsylvania, went dormant in 2019 after billowing water vapor into the sky for four decades. Its owner at the time, Exelon, permanently shut down the Unit 1 reactor, citing “severe economic challenges.”
Unit 1 is one of a dozen reactors that closed in the U.S. over the past decade as nuclear industry struggled to compete against cheap and abundant natural gas. But the fortunes of the industry have shifted dramatically this year as deep-pocketed technology companies turn to nuclear power to meet the tremendous electricity consumption of their future business: artificial intelligence.
“This is a plant that we ran and ran very well,” plant manager Trevor Orth told the NRC at an Oct. 25 meeting. “We shut it down. We understand how we shut it down, and we have a good idea of how we’re going to restart this.”

While Constellation will restore the plant, it will ditch the name Three Mile Island. The plant will be rechristened the Crane Clean Energy Center, after the late CEO of Exelon, Chris Crane. Constellation said the restart will cost $1.6 billion, financed by the company’s own funds.
Microsoft has made the restart of Unit 1 possible through an agreement to purchase the full electricity output from the plant for 20 years, a sign of the growing role the tech sector is playing in shaping the future of the U.S. power industry.
Microsoft said the agreement is part of its strategy of meeting the growing electricity needs of its data centers with power that is free of carbon dioxide emissions in an effort to mitigate the impact of its business on the climate.

Those data centers are playing a critical role in the U.S. economy, housing servers that run the cloud computing that businesses and consumers now rely on for life’s digital daily tasks. They are also essential for the development of artificial intelligence, technology that is viewed as critical for the nation’s future economic competitiveness and national security.
With four years until the planned restart, one of the big uncertainties is whether Constellation can deliver the power to Microsoft on time. Nuclear projects are notoriously plagued by long delays, big cost overruns and cancellations. But Unit 1 is in good condition and Constellation is confident the plant will restart on schedule, said Bryan Hanson, the company’s chief generation officer.
Most of the restoration at Unit 1 will be normal maintenance work that Constellation conducts regularly on its fleet of nuclear plants, Hanson said during an Oct. 30 tour of the plant.
“Not an ounce of concrete needs to be poured, not one piece of rebar needs to be tied, not one cable needs to be pulled. The infrastructure is here,” the executive said. “The challenge of delays — I don’t see it.”

Constellation’s decision to restart Three Mile Island follows Holtec International’s decision to restart its Palisades nuclear plant in Michigan. Palisades is poised to become the first reactor to restart operations in U.S. history in 2025 after shutting down.
Holtec has plans to nearly double the power capacity of the facility in the 2030s by building two small modular reactors, next-generation technology that promises to make nuclear plants less costly and easier to deploy.
Amazon and Alphabet’s Google recently announced investments in small modular reactors.
While Constellation has not committed to building a small modular reactor at any of its plants yet, Hanson said the company is open to working with the tech sector to build new nuclear reactors in the U.S.
“If our customers come to us again, like a Microsoft, and say ‘we want to help you build new nuclear’ — we’ll probably join hands and figure out a way to do that,” Hanson said.
Lingering fears
Unit 1 is a short walk from the site of the worst nuclear accident in U.S. history.
The partial meltdown of the Unit 2 reactor at Three Mile Island in 1979 had a chilling effect on the development of new nuclear plants in the U.S. Unit 2 has not operated since the accident and is being decommissioned by its current owner, Energy Solutions, a private nuclear services company.
Unit 1 operated safely and efficiently before it was shut down for economic reasons, said Mike Goff, acting assistant secretary for the Office of Nuclear Energy at the Department of Energy.
But Pennsylvania state Rep. Thomas Mehaffie said his constituents have mixed feelings about the restart of Unit 1, particularly those who are old enough to remember the accident at Unit 2.

“Of course people who were here during that time frame, who are older — there is concern. There always has been concern,” said Mehaffie, who represents the communities around Three Mile Island at the state legislature in Harrisburg. Mehaffie’s father was a union electrician who helped build the nuclear plants.
Hanson said the nuclear industry has learned from this chapter of its history.
“The 1979 accident taught us that our standards weren’t right at the time,” Hanson said. The U.S. nuclear industry today has the best safety, reliability and operational standards in the world, he said.
While some constituents have concerns, others see the economic value that the restart will bring, Mehaffie said. The restart of Unit 1 will bring an estimated 3,400 jobs to the region, according to a study by the Pennsylvania Building & Construction Trades Council.
Grid reliability
The planned restart of Three Mile Island is also a step to help ensure the region’s electric grid remains reliable, Mehaffie said. Unit 1 will bring back 835 megawatts of carbon-free electricity, equivalent to the consumption of more than 600,000 homes, at a time when the grid is on the brink of faltering.
Electricity demand is outpacing supply, as power plants, particularly those that run on coal, are retired faster than new capacity is built, grid operator PJM Interconnection warned in July. PJM operates the grid in Pennsylvania and 12 other states.
“Grid reliability is everything,” Mehaffie said.
PJM has forecast that electricity demand will surge nearly 40% by 2039 due to the expansion of data centers, manufacturing and the electrification of industry and transportation. Meanwhile, 40 gigawatts of power generation is at risk of retirement by 2030; that’s about 21% of PJM’s installed capacity.
“We’re seeing potentially catastrophic early retirements of dispatchable resources,” Mark Christie, a commissioner at the Federal Energy Regulatory Commission, said during a public hearing Nov. 1.

Microsoft said the electricity it will be purchasing from Unit 1 will feed into the grid and will not directly power its data centers. Microsoft is committed to bolstering the grid as it secures power for its data centers, said Alistair Speirs, senior director of global infrastructure for Microsoft’s Azure cloud platform.
“When we operate in the community, if we’re not stabilizing, adding resiliency to the grid, then it’s hard for us to keep our social license to operate,” Speirs said.
Microsoft is not involved in the physical restoration of the plant, Hanson said, but Constellation is providing status reports to the company.
Restoration and restart timeline
Constellation laid out how it plans to restart the plant in the company’s first public meeting with the Nuclear Regulatory Commission on Oct. 25. While Wall Street is generally bullish on the restart, Citi has cautioned that Constellation could face challenges in completing the project on schedule.
“Given the regulatory and physical challenges, we assume that [Constellation] is likely to experience some delays and cost overruns to execute on the restart,” Citi analyst Ryan Levine told clients in an Oct. 14 note.
Citi initiated coverage of Constellation with a neutral rating in October on delay concerns. Constellation’s stock has gained more than 90% since the start of the year and 12% since the Three Mile Island restart was announced Sept. 20.
Levine is an outlier. The vast majority of analysts rate the stock a buy or strong buy, with the average price target predicting more than 23% upside.

Hanson said crucial and expensive equipment such as the steam generators and main power generator have undergone inspection and maintenance by Constellation and are in good condition.
The steam generators were replaced in 2009 and are ready for restart, he said. The internals of the main power generator, built by General Electric nearly 50 years ago, were replaced a little over a decade ago, he said. The main generator has been cleaned and needs some routine maintenance, he said.
The plant’s main power transformers need to be replaced at a cost of $75 million to $100 million, Hanson said. The transformers are on order with delivery expected in late 2026, he said.
One of the cooling towers has been gutted and will be refurbished. The analog control room will remain the same with the exception of some rewiring, Hanson said.
The simulator that mimics the control room also needs to be restored so plant operators can be trained there. One of the most critical items for restoring plant operations is training operators for NRC certification, a process that takes about 18 months, Hanson said.

Constellation is currently prohibited from operating and loading fuel into the reactor vessel because the plant was permanently shut down. Constellation plans to file an exemption request in November that would remove these restrictions if approved by the NRC.
“That will officially mark the start of our restart activities,” Dennis Moore, senior manager of licensing at Constellation, told the NRC.
Constellation plans to file a request to change the plant’s name from Three Mile Island to the Crane Clean Energy Center in February. Later in 2025, Constellation will submit filings on the plant’s technical specifications, environmental impact, emergency plan, and site security plan for NRC review, the company said.
Constellation intends to send an operational readiness letter to the NRC by July 2027. The company would then begin testing and return to power if the NRC determines that the plant is ready to operate and authorizes placing fuel in the reactor.
In the meantime, Constellation does not need NRC permission to “start turning wrenches and doing restoration work” at the plant, said Scott Burnell, a spokesperson for the regulator. The NRC will be monitoring the work to make sure the regulator’s requirements are met, Burnell said.
The restarts at Three Mile Island and Palisades will likely secure NRC approval, Goff said.
“They are an independent agency, but I expect if the safety cases are presented, they’re going to approve it,” Goff told CNBC in September.
Jackery launches its new compact Explorer 240D 256Wh power station at Amazon with first savings from $139
Running alongside its Early Prime Day Sale, Jackery has launched its newest backup power solution, and this one is not only coming in a more compact form factor to replace the discontinued Explorer 100 Plus, but its also seeing its first savings coming from Amazon. You can now pick up the Jackery Explorer 240D Portable Power Station at $139 shipped, which beats out the brand’s direct pricing (though it is stated on the landing page that it’s not yet available to buy), where it’s still sitting/starting at its full $209 rate. While this initial launch discount continues, you can be some of the first to score one for your on-the-go charging needs with a 33% markdown that cuts $70 off the going rate and sets the bar for future discounts. Head below for more on this and its bundle options.
I, like many, was very upset to see Jackery’s Explorer 100 Plus disappear from markets, but today the brand is giving us the official replacement in the form of its new Explorer 240D power station. This new compact solution brings along a 256Wh LiFePO4 battery capacity (69,189.19mAh) that significantly beats many power banks and other compact power stations on the market, alongside four output port options for your devices: three USB-Cs and a solo USB-A. You’ll be getting up to 200W of power through those ports, with the brand even rating this model to last for a minimum of 6,000 charge cycles, meaning you’ll get over 16 years of use, even when using it every single day.

Lucid (LCID) appears to be successfully ramping up Gravity production, as a large number of electric SUVs have been spotted exiting its Arizona factory in a new drone flyover.
The Gravity is a big step forward for Lucid. The automaker has proven its capacity to produce a super-powerful and efficient powertrain with the Air, but it is a luxury sedan, which is hardly a popular segment in the US, where the company is based.
Lucid used its learnings from the Air to launch the Gravity, an electric SUV, which is a much more popular vehicle segment in North America.
There has been considerable confusion about the Gravity ramp-up. The vehicle has been undoubtedly positively reviewed by the industry, but the rollout has been questioned.

Recently, a news report claimed that Lucid only sold nine Gravity SUVs in its first six months on the market.
Nick Twork, Lucid’s head of communication, quickly shut down the report without confirming the actual number of Gravity delivered to customers.
While there’s no doubt that Lucid delivered more than nine Gravity SUVs, it’s true that the automaker has had issues ramping up production. Lucid’s interim CEO, Marc Winterhoff, confirmed as much during the last earnings call.
Now, we finally get some clear evidence that Lucid is ramping up Gravity production, thanks to a new drone flyover of the factory in Arizona:
The drone flyover took place on Monday, September 22nd, 2025, and it shows a large number of Gravity electric SUVs in lots being prepared for shipping.
There appear to be more Gravity units than Air’s and there are hundreds of Gravity SUVs – possibly even over a thousand:
The Acura ZDX is officially dead. Acura’s sole electric SUV will not return for another model year. Despite better-than-expected sales, Acura is preparing for a new EV.
The ZDX is dead as Acura bets on the RSX and hybrids
Honda confirmed plans to end production of the Acura ZDX on Wednesday. Acura’s electric SUV is assembled by GM at its Spring Hill, Tennessee, plant.
It’s also based on the same Ultium EV platform that powers all Chevy, GMC, and Cadillac electric models. GM was slated to begin building the 2026 model year later this month, but that will no longer be the case.
A note sent to plant workers said Honda “has decided to cancel all future production” of the Acura ZDX. A Honda spokesperson confirmed the plans to CNBC, saying the move was due to changing market conditions.

“To better align our product portfolio with the needs of our customers and market conditions, as well as our long-term strategic goals, we can confirm the Acura ZDX has ended production,” the spokesperson said in an email to CNBC.

The Honda Prologue, another GM-based electric SUV, will return for a 2026 model year. Honda’s spokesperson confirmed that the Prologue will continue to be produced at GM’s plant in Mexico.
Acura is shifting its focus to its sporty new electric SUV, the RSX, which will be manufactured at Honda’s EV Hub in Ohio, starting in the second half of 2026. The luxury brand also plans to reintroduce hybrids, but no specifics have been revealed.

The changes will not impact workers’ employment at the facility, according to GM’s memo. It will add additional gas-powered Chevy Blazer production and engines, starting in 2027.
Electrek’s Take
Honda’s decision to discontinue the ZDX is not a huge surprise. Although sales were higher than expected, outselling the Cadillac Lyriq in the first half of 2025, Honda is preparing for a new generation of vehicles, starting with the new Acura RSX.
The 2026 Acura RSX will be the first vehicle to debut on Honda’s in-house EV platform. It will also be the first model to feature Acura’s ASIMO OS, promising to be an advanced AI-based system that will control all infotainment, ADAS, and other connected features.
Honda says the RSX will be a “Software Defined Vehicle,” which will get smarter and more advanced over time through over-the-air (OTA) updates.
With the $7,500 EV tax credit ending this month, Honda is offering a few discounts that are hard to beat, including over $20,000 off the Prologue. The Acura ZDX has nearly $30,000 in savings, but that’s if you can find one. You can use our links below to view inventory in your area.
