Microsoft said Wednesday it has signed a power purchase agreement with nuclear fusion startup Helion Energy to buy electricity from it in 2028.
The deal is a notable vote of confidence for fusion, which is the way the sun makes power and holds promise of being able to generate nearly unlimited clean power, if it can be harnessed and commercialized on earth. For decades, fusion been lauded as the holy grail of clean energy — tantalizing because it’s limitless and clean, but always just out of reach.

As responding to climate change has become an increasingly urgent goal for companies and countries around the globe, investors have poured $5 billion into private fusion companies looking to turn that holy grail into electrons flowing through wires.
Microsoft’s agreement to buy electricity from Helion is the first time a fusion company has inked a deal to sell electricity, according to Andrew Holland, the CEO of the Fusion Industry Association.
“This is the first time that I know of that a company has a power purchase agreement signed,” Holland told CNBC. “No one has delivered electricity, and Helion’s goal of 2028 is aggressive, but they have a strong plan for how to get there.”
Helion was founded in 2013 and currently has about 150 employees, with headquarters in Everett, Wash. One of the early and most significant investors in Helion, Sam Altman, is also a founder of OpenAI, the artificial intelligence organization that developed the chat platform ChatGPT, in which Microsoft has invested many billions of dollars. Altman believes the two deals are equally important and correlated components of the future he sees for humanity.
“My vision of the future and why I love these two companies is that if we can drive the cost intelligence and the cost of energy way, way down, the quality of life for all of us will increase incredibly,” Altman told CNBC. “If we can make AI systems more and more powerful for less and less money — same thing we are trying to do with energy at Helion — I view these two projects as spiritually very aligned.”

If demand for and use of artificial intelligence continues to increase, then that will increase demand for energy, too.
The potential of fusion is “unbelievably huge,” Altman told CNBC. “If we can get this to work — if we can really deliver on the dream of abundant, cheap, safe, clean energy that will transform society. It’s why I’ve been so passionate about this project for so long.”
In 2021, Altman told CNBC he put $375 million into Helion. As of Tuesday, this is still his largest investment ever, Altman told CNBC. In total, Helion has raised raised $577 million.
Why Helion is announcing a 2028 goal now
As part of the power purchase agreement, Helion is expected to have its fusion generation device online by 2028 and to reach its target power generation of 50 megawatts or more within an agreed-upon one-year ramp up period. When the fusion device is fully up to speed producing 50 megawatts of energy, it will be able to power the equivalent of approximately 40,000 homes in Washington state.
While Helion’s deal with Microsoft is to get 50 megawatts online, the company eventually aims to produce a gigawatt of electricity, which is one billion watts, or 20 million times the 50 megawatts it is selling to Microsoft.
Microsoft will pay for the megawatt hours of electricity as Helion delivers them to the grid.
“This is a real PPA, so there’s financial penalties if Helion can’t deliver power. So we’ve really put our skin in the game on this too — that we believe we can deliver this power and are committed to it with our own financial incentives,” David Kirtley, CEO at Helion, told CNBC.

Altman advocated for the two companies to work together, he told CNBC, but the deal is the result of work Helion has done independently. “It was not my doing,” he said.
Microsoft and Helion have been working together for years, Kirtley told CNBC. “The first visit we had from the Microsoft team was probably three of our prototypes ago, so many years ago. And then we’ve been working very closely with their data center technology team here in Redmond,” Kirtley said.
After all, Microsoft needs power and has aggressive climate goals. Microsoft has a goal to have 100% of its electricity consumption, 100% of the time, matched by zero-carbon energy purchases by 2030. Carbon-free energy includes hydro, nuclear and renewables for Microsoft, a Microsoft spokesperson told CNBC.
“We are optimistic that fusion energy can be an important technology to help the world transition to clean energy,” Brad Smith, president at Microsoft, said in a written statement. “Helion’s announcement supports our own long term clean energy goals and will advance the market to establish a new, efficient method for bringing more clean energy to the grid, faster.”

For Helion to be able to deliver electricity generated by fusion to customers requires years of advance planning on the transmission and regulatory fronts.
In that way, announcing a contract now to sell electricity in 2028 gives Helion time to plan and to pick a location in Washington State to put this new fusion device.
“One reason we’re doing the announcement today is that so we can be working with the communities involved, we can be working with regulators, and the power utility on citing this right now,” Kirtley told CNBC. “Even five years is a short amount of time to be hooked up to the grid. And we want to make sure that we can do that.”
Indeed, the transmission system in the United States, meaning the series of wires that carry electricity from where it is generated to where it is used, is largely tapped out. Getting new power generation connected to the grid can take years. Helion is working with Constellation to secure its transmission needs.
‘We’re not here to build systems in a lab’
The best-known pathway to commercializing fusion is with a donut-shaped device called a tokamak. The international fusion project under construction in Southern France called ITER is building a tokamak, and Commonwealth Fusion Systems, a fusion start-up spun out of MIT which has raised more than $2 billion in funding, is using tokamak technology. For comparison, CFS plans to have its first power plant on the grid and selling electricity in the early 2030s.
Helion is not building a tokamak. It is building a long narrow device called a Field Reversed Configuration.

Broadly speaking, Helion’s approach involves shooting plasma (the fourth state of matter after solid, liquid and gas) from both ends of the device at a velocity greater than one million miles per hour. The two streams smash into each other, creating a superhot dense plasma, where fusion occurs.
Helion is currently building its seventh-generation fusion machine, named Polaris, which it aims to produce electricity with by next year, Kirtley told CNBC.
“We’re not here to build systems in a lab. We’re here to sell electricity. This is always been the dream,” Altman told CNBC.
So far, Helion has been able to generate energy with its fusion prototypes, but it has not yet built a device that creates more electricity than it uses to run the fusion device. So the firm has a lot of work ahead.
To that, Altman says: “There were a lot of people that were doubting A.I. six months ago, too.”
“Either the technology here is going to work or not. There’s a lot of huge challenges still to figure out — how are we going to get the cost super-low, how are we going to manufacture at scale — but on the ability to actually do the physics, we feel very confident,” Altman told CNBC. “And I think it’s fine for people to doubt it. But also the way that you eventually reduced that doubt is to show to show people it actually works in the commercial setting, like delivering on this deal.”
Helion has been making progress on some key hurdles.
For example, the company has started making its own capacitors, which are sort of like super-efficient batteries and one of Helion’s very significant capital costs.
It has also started to make the very rare fuel it uses, helium three, which is a very rare type of helium with one extra neutron. It used used to get helium-three from the U.S. government strategic reserves.
Next up, Helion has to demonstrate that its devices can work reliably for long periods of time, and Kirtley has a team working on durability of the components used in the device.
If Helion can be successful, it’s going to be a landmark for the entire fusion industry.
“This really signals that a fusion era is coming. And we’re all very excited about it,” Kirtley told CNBC.
Enel North America and food and snacks giant Mars have signed a massive clean energy deal that will power up Mars’s operations with Texas solar.
The two companies completed a power purchase agreement (PPA) for the full output – all 851 megawatts (MW) – of three Texas solar farms. Together, those plants are expected to deliver 1.8 terawatt-hours of electricity annually, the equivalent of enough electricity to power 150,000 homes. That makes this Enel’s largest corporate PPA worldwide.
Michele Di Murro, CEO of Enel North America, said the deal “shows how renewables are among the fastest and most affordable solutions to meet the nation’s energy needs. Through these agreements, we’re adding clean capacity to the Texas grid while supporting a leading manufacturer’s sustainability goals.”
For Mars, the move goes beyond just greening its own factories. Kevin Rabinovitch, global VP of sustainability at Mars, explained that this PPA “lets us bring demand for all the electricity used in our value chain to the clean energy market in a highly efficient manner. The more demand we create together, the faster we can build the future we all want.”
All three solar farms will use sheep grazing to manage vegetation, a dual-use practice Enel has scaled through the largest solar grazing agreement in the US.

Lease deals get all the headlines, but 75% of new car buyers still finance their cars, indicating that they want to own their vehicles once the payments are done. If that sounds like you, and you’ve been holding out for relief from sky-high payments, a wave of new EVs are now available with 0% financing — making it one of the best months yet to buy a new EV.
Every month, Electrek readers looking for great deals on a new EV flock to our lease deal posts. Recently, however, the comments have been asking another crucial question: what about EV deals for the people who want to buy, instead of leas?
You asked, we listened. This roundup is for that 75% of new car buyers who choose to finance their cars instead of lease — so here’s a list of all the 0% financing deals on EVs you can get in September, 2025.
As I put this list together, I realized there were plenty of ways for me to present this information. In the end, I decided to present these deals in alphabetical order, by brand name (make). And, as for which deals are new this month? You’re just gonna have to check the list. Enjoy!
Acura ZDX
New for the 2024 model year, the Acura ZDX uses GM Ultium battery and drive technology, but the styling, interior, and infotainment are all Honda, delivering GM-level parts support with Honda-level fit, finish, and quality. Add in standard Apple CarPlay support, 0% financing for up to 72 months, and $7,500 customer cash through September 30th, and the ZDX becomes easily one of the best sporty crossover values on the market.
Chevy Equinox EV
With an impressive combination of affordability, practicality, and advanced features, the Chevy Equinox is a standout EV. And with an EPA-estimated range of up to 319 miles and a starting price under $35,000, it’s no wonder they’re flying off dealer lots.
For well-qualified buyers, Chevrolet is offering 0% APR financing for up to 60 months through GM Financial through September 30th. That offer can be paired with the $7,500 federal EV tax credit (which you can claim at the dealer), along with up to $1,250 in additional discounts for Costco members, depending on membership level.
Dodge Charger
Dodge is hoping that at least a few muscle car enthusiasts with some extra cash will find their way to a Dodge store and ask for the meanest, loudest, tire-shreddingest muscle car on the dealer’s lot without caring too much about what’s under the hood.
For them, Dodge has the new electric Charger with up to 670 battery-backed horsepower. And if you still owed money on the Hemi you just totaled, Dodge will help get the deal done on its latest retro-tastic ride with a $7,750 retail cash allowance or 0% financing for up to 72 months — and that’s before any dealer discounts.
Ford F-150 Lightning
America’s best-selling electric truck offers V2x technology, a nationwide dealer network, a universe of aftermarket accessories, and a look that blends into the crowd. This month, this proven pickup adds 0% interest financing for up to 72 months. Ford Pro customer can get access to advanced telematics and, in some cases, even get help sourcing additional grants and rebates, too.
GMC Hummer EV
The biggest of GM’s Ultium-based EVs are seriously impressive machines, with shockingly quick acceleration, plus on-road handling that seems to defy the laws of physics once you understand that these are, essentially, medium-duty trucks. This month, GMC is doing its best to move out its existing inventory with 0% financing for well-qualified buyers plus $1,250 in discounts for select Costco members. So, if you’re a fan of heavy metal you’ll definitely want to stop by your local GMC dealer and give the Hummer EV a test drive.
GMC Sierra EV
In addition to offering a solid Powerwall alternative, these big Ultium-based EVs from GM’s “three letter bandit” commercial brand are just as impressive as their Hummer stablemates, but one-up the Hummers with heavy-duty towing prowess and the added capability of bidirectional charging baked in. And, like the Hummer, GMC is doing its best to move out its existing inventory of Denali and AT4 model Sierra EVs with 0% financing for well-qualified buyers plus $1,250 in discounts for select Costco members.
Honda Prologue
Like the Acura ZDX at the top of this list, the Honda Prologue was blends the excellent GM Ultium EV platform with Honda sensibilities and Apple CarPlay to create a winning combination. It’s no surprise that it’s one of the top-selling electric crossovers — and to move out as many as possible before the $7,500 federal tax credit goes away, Honda is offering 0% APR for up to 60 plus up to an additional $2,000 in Honda Loyalty or Conquest cash.
Hyundai IONIQ 6
The last of the streamliners, the IONIQ 6 has influences from Ferry Porsche and Raymond Loewy without looking like a copy of either. In addition to being a future classic, it’s efficient, comfortable, quick, offers up to 361 miles of range, can charge just about anywhere, and (now through the end of the month), can be financed with 0% interest for up to 48 months or $7,500 in customer bonus cash on all trims.
If you’re flexible on color, Hyundai dealers with “aged inventory” will give you an extra $1,000, for $8,500 total incentive dollars on your IONIQ 6.
Jeep Wagoneer S
The Jeep Wagoneer S is a slick, capable, street-oriented EV that’s been inexplicably saddled with a sloping roof and spoiler that eats away at the electric SUV’s ultimate utility (that’s the “U” part), but if you can get past that minor caveat, this first-ever battery-powered Jeep is ready to deliver. With $7,750 retail cash allowance or 0% financing for up to 72 months before dealer discounts through September 30th, the Wagoneer S might just be the best EV deal going.
Kia Niro EV
Kia is doing a phenomenal job moving its supercar-baiting EV6 and ultra-capable EV9 family trucksters, but the under-mentioned and underrated little Niro EV seems like it could use a little help. To that end, Kia is offering 0% interest financing or up to $7,500 customer cash on select examples of the little urban runabout now through September 30th.
Nissan Ariya
I’ve already said that the Nissan Ariya didn’t get a fair shake. If you click that link, you’ll read about a car that offers solid driving dynamics, innovative interior design, and all the practicality that makes five-passenger crossovers the must-haves they’ve become for most families. With up to 289 miles of EPA-rated range, Tesla Supercharger access, and 0% interest from Nissan for up to 72 months or up to $10,000 Customer Cash (that’s not a typo) undecided EV buyers could do a lot worse than to give the Ariya a chance to win them over.
Polestar 3
Sleek, Scandinavian, and seriously quick, the Polestar 3 is the lovechild of Swedish brand Volvo and Chinese brand Geely’s billions. As such, it delivers both Scandinavian style and high-tech substance with dual-motor power, a minimalistic, luxurious cabin, and Android Auto baked right in. The Polestar 3 was designed to turn heads while keeping daily driving effortless, and through the month of September, it’s sure to turn even more heads with 0% financing for up to 72 months through Polestar Financial Services and a $10,000 Clean Vehicle Incentive in some markets.
Put it all together, and the Polestar 3 stands out as one of the most compelling premium EV SUV deals of the month.
Subaru Solterra
The first-ever electric Subaru had a rocky start (no pun intended), but this off-road-ready sibling of the Toyota bZ4X seems like a solid mid-size electric crossover with some outdoorsy vibes and left-leaning granola style that offers more than enough utility to carry your mountain bikes to the trail or your inflatables out to the pond. Add in 227 miles of range, some big discounts, and 0% financing for up to 72 months, and this should be a great month for electric Subaru fans to drive home in a new Solterra.
Volkswagen ID.4
One of the most popular legacy EVs both in the US and Europe, the ID.4 offers Volkswagen build quality and zippy around-town handling. Everyone I know who has one loves it, and VW dealers are getting aggressive with discounts, making this fast-charging, 291 mile EPA-rated range, 5-star safety rated EV a value proposition that’s tough to beat.
This month, get a Volkswagen ID.4 with 0% financing for up to 72 months or up to $5,000 customer cash. You’ll need to do some math to see which offer works best for you.

EV charging networks SWTCH Energy and FLO have signed a roaming agreement that lets drivers charge on either network with just one app, removing the need to juggle multiple accounts or payment methods.
One of the biggest frustrations for EV owners is charging network fragmentation. Using multiple apps and memberships makes it clunky and time-consuming for drivers to plug in, especially on road trips. This new agreement gives drivers access to tens of thousands of chargers on SWTCH and FLO’s networks.
If you’re using the SWTCH or FLO app, you can now see and use chargers from both networks. Your existing payment method works across the board, and expanded charger visibility makes trip planning easier. That should mean a smoother, more consistent experience.
SWTCH CEO Carter Li said, “SWTCH users now have access to more than 70,000 chargers across North America. We’re creating the seamless, integrated charging ecosystem that drivers deserve.” FLO CEO Louis Tremblay added that FLO’s roaming agreements already give its members access to more than 110,000 public chargers, and teaming up with SWTCH further strengthens that coverage.
Both companies already have roaming deals with other charging networks in Canada and the US.
