TerraPower, a start-up co-founded by Bill Gates to revolutionize designs for nuclear reactors, has picked Kemmerer, Wyoming, as the preferred location for its first demonstration reactor. It aims to build the plant in the frontier-era coal town by 2028.

Constructing the plant will be a job bonanza for Kemmerer, with 2,000 workers at its peak, said TerraPower CEO Chris Levesque in a video call with reporters on Tuesday.

It will also provide new clean-energy jobs to a region dominated today by the coal and gas industry. Today, a local power plant, coal mine, and natural gas processing plant combined provide more than 400 jobs — a sizeable number for a region that has only around 3,000 people.

“New industry coming to any community is generally good news,” Kemmerer Mayor William Thek told CNBC. “You have to understand, most of our nearby towns are 50 miles or more from Kemmerer. Despite that, workers travel those distances every day for work in our area.”

For TerraPower, picking a location was a matter of geological and technical factors, like seismic and soil conditions, and community support, said Levesque.

Once built, the plant will provide a baseload of 345 megawatts, with the potential to expand its capacity to 500 megawatts.

For reference, one gigawatt or 1,000 megawatts of energy will power a mid-sized city, and a small town can operate on about one megawatt, according to a rule of thumb Microsoft co-founder Gates provided in his recent book, “How to Avoid a Climate Disaster.” The United States uses 1,000 gigawatts and the world needs 5,000 gigawatts, he wrote.

It will cost about $4 billion to build the plant, with half of that money coming from TerraPower and the other half from the U.S. Department of Energy’s Advanced Reactor Demonstration Program.

“It’s a very serious government grant. This was necessary, I should mention, because the U.S. government and the U.S. nuclear industry was, was falling behind,” said Levesque.

“China and Russia are continuing to build new plants with advanced technologies like ours, and they seek to export those plants to many other countries around the world,” Levesque said. “So the U.S. government was concerned that the U.S. hasn’t been moving forward in this way.”

Once built, it should provide power for 60 years, Levesque said.

How TerraPower’s reactors are different

The Kemerrer plant will be the first to use an advanced nuclear design called Natrium, developed by TerraPower with GE-Hitachi.

Natrium plants use liquid sodium as a cooling agent instead of water. Sodium has a higher boiling point and can absorb more heat than water, which means high pressure does not build up inside the reactor, reducing the risk of an explosion.

Also, Natrium plants do not require an outside energy source to operate their cooling systems, which can be a vulnerability in the case of an emergency shut-down. This contributed to the 2011 disaster at the Fukushima Daiichi nuclear plant in Japan, when a tsunami shut down the diesel generators running its back-up cooling system, contributing to a meltdown and release of radioactive material.

Natrium plants can store also heat in tanks of molten salt, conserving the energy for later use like a battery and, enabling the plant to bump its capacity up from 345 to 500 megawatts for five hours.

The plants are also smaller than conventional nuclear power plants, which should make them faster and cheaper to build than conventional power plants. TerraPower aims to get its plants to a cost of $1 billion, a quarter of the budget for the first one in Kemmerer.

“One important thing to realize is the first plant always costs more,” said Levesque.

Finally, Natrium plants produce less waste, a problematic and dangerous by-product of nuclear fission.

‘Times are changing’

The Kemmerer plant still faces a couple of hurdles, including federal permitting.

“There’s a comprehensive licensing process overseen by the Nuclear Regulatory Commission, that, frankly, is expensive. There, there are many, many reviews,” Levesque said.

Also, the fuel that the Natrium plant uses is called high-assay low-enriched uranium, or HALEU, which is not yet available at commercial scale.

The existing nuclear fleet in the United States runs uranium-235 fuel that is enriched up to 5%, the Department of Energy says, while HALEU is is enriched between 5% and 20%.

“Sadly, we don’t have this enrichment capability in the U.S, today. And this is an area of great concern of the US government, and specifically the Department of Energy,” Levesque said.

But it’s coming, Levesque said. “I’m really certain that we’re going to establish that capability” in another public-private partnership, similar to the way the Natrium power plant demonstration is being built.

Once built, the plant will be turned over to Rocky Mountain Power, a division of Berkshire Hathaway Energy’s PacifiCorp, to operate.

There, it will become part of Rocky Mountain Power’s decarbonization plan.

Coal-fired plants like the Naughton facility in Kemmerer “have benefited our customers for decades with very low cost power,” Gary Hoogeveen, president and CEO of Rocky Mountain Power, said Tuesday. “And we appreciate that. But times are changing,” Hoogeveen said.

“External requirements from the federal government, state governments, regulatory agencies are going to require that we change and we’re going to need to decarbonize and as we go down that path, we see the Natrium project as being incredibly valuable to our customers.”

“Wyoming is a tremendous wind resource state,” Hoogeveen said. And so far, Rocky Mountain Power has built 2,000 megawatts of wind power capacity in Wyoming, and that’s going to grow. “We expect to build many more thousands of megawatts of wind capacity in the state.”

But the nuclear power plant in Kemmerer will be a key bridge for the state, Hoogeveen said.

“It is a great spot for absorbing the intermittency of of the renewable resources and using the storage that’s built in that is so incredibly valuable to us,” he said.

Germany’s largest offshore wind farm under construction, EnBW’s He Dreiht, just hit a big milestone: The first enormous turbine is now up in the North Sea.

He Dreiht – which means “it spins” in Low German – is using Vestas’s massive 15 megawatt (MW) turbines, the first project in the world to install them. Just one spin of one of the rotors can generate enough electricity to power four households for an entire day.

When it’s finished, He Dreiht will have 64 mega turbines cranking out 960 megawatts (MW) of clean power – enough to supply around 1.1 million homes. And it’s being built without any government subsidies.

EnBW, one of Germany’s major energy companies, has been working in offshore wind for more than 15 years, but He Dreiht is their biggest project yet. “It will play a key role in helping us to significantly grow our renewable energy output from 6.6 GW to over 10 GW by 2030,” said Michael Class, who heads up EnBW’s generation portfolio development.

The project is a win for Vestas, too. “With the installation of the first V236-15.0 MW, we have reached an important milestone for both the He Dreiht project and our offshore ramp-up, which helps Germany build a more secure, affordable, and sustainable energy system,” said Nils de Baar, president of Vestas Northern & Central Europe.

He Dreiht is located about 85 kilometers (53 miles) northwest of Borkum and 110 kilometers (68 miles) west of Helgoland. At peak times, more than 500 workers will be out at sea building the farm, using a fleet of more than 60 ships. EnBW’s offshore team in Hamburg is running the show.

The installation process is a major operation. The 64 foundations were already set in the seabed last year. Parts for the turbines are loaded onto the installation vessel Wind Orca in Esbjerg, Denmark, and shipped out in a 12-hour journey to the construction site. From there, the turbines are lifted into place. Meanwhile, crews are also working on internal wind farm cabling.

A partner consortium made up of Allianz Capital Partners, AIP, and Norges Bank Investment Management owns 49.9% of the shares in He Dreiht.

Tesla gives update on Tesla Semi factory, says on track for volume production in 2026

Tesla has released a quick update about its Tesla Semi factory in Nevada. It says that it is on track for volume production of the electric semi truck in 2026.

The Tesla Semi was first scheduled to go into production in 2019, but it has faced numerous delays.

Now, it appears that there is finally some momentum to bring it to volume production.

For the last two years, Tesla has been working to build a new factory next to Gigafactory Nevada, where it builds the battery packs and drive units for most of its electric vehicles built in North America.

Today, Tesla released a “progress update on the factory, confirming that it finished building and it’s now working on deploying the production lines:

Tesla had previously mentioned aiming for volume production by 2025, but it is now only talking about starting production toward the end of the year and ramping up next year.

The automaker reiterated its planned production capacity of 50,000 units.

We recently reported that an early Tesla Semi customer, Ryder, stated that the electric truck program is experiencing more delays and a price increase described as “dramatic.”

They now expect to take deliveries of their first trucks later in 2026 and said that the price has increased “dramatically,” leading them to scale back their pilot program from 42 to 18 Tesla Semi trucks.

When originally unveiling the Tesla Semi in 2017, the automaker mentioned prices of $150,000 for a 300-mile range truck and $180,000 for the 500-mile version. Tesla also took orders for a “Founder’s Series Semi” at $200,000.

However, Tesla didn’t update the prices when launching the “production version” of the truck in late 2022. Price increases have been speculated, but the company has never confirmed them.

Vietnamese solar panel maker Boviet Solar just opened the doors to its first US factory — a huge new PV module plant in Greenville, North Carolina.

The company dropped $294 million into the state-of-the-art facility, which will pump out Boviet’s Gamma Series monofacial and Vega Series bifacial solar panels. They’re using advanced PERC and N-Type solar cell tech, which basically means these panels are built to deliver higher efficiency and better performance across residential, commercial, industrial, and utility-scale projects.

The Greenville factory’s first phase is now online with an annual PV module output capacity of 2 gigawatts (GW). For Phase 2, which is scheduled to come online in the second half of 2026, Boviet will invest another $100 million to add 600,000 square feet and ramp up to another 2 GW. It will make high-efficiency solar cells.

Once both phases are complete, Boviet’s campus will cover more than 1 million square feet of manufacturing and R&D space. It’s one of the biggest clean energy manufacturing projects North Carolina has ever seen.

The jobs impact is significant, too. The first phase will create 460 skilled local jobs. Phase 2 is expected to add another 908, bringing the total to over 1,300 direct jobs, plus nearly 2,000 more indirect jobs across the region. That’s good news for Pitt County’s economy, real estate market, and workforce training programs.

“This facility is not just creating jobs, but creating opportunity, innovation, and a stronger foundation for eastern North Carolina,” said Senator Kandie Smith. Governor Josh Stein added that Boviet Solar’s move shows how North Carolina is leading the way in clean energy growth.
