Alphabet’s Google and Kairos Power will deploy an advanced nuclear plant linked to the Tennessee Valley Authority’s electrical grid by 2030, the businesses introduced Monday.
TVA has agreed to buy as much as 50 megawatts of energy from Kairos’ Hermes 2 reactor. It is the primary utility within the U.S. to signal an influence buy settlement with an advanced reactor like Hermes 2, in line with the businesses.
Hermes 2 is the primary deployment below an agreement that Google and Kairos signed final 12 months to launch the startup’s nuclear expertise at a business scale. The reactor’s output is the equal of the consumption of about 36,000 properties. The electrical energy will assist energy Google’s knowledge facilities in Montgomery County, Tennessee, and Jackson County, Alabama.
Google, Kairos and TVA mentioned their collaboration will transfer the U.S. a step nearer to deploying advanced nuclear reactors by ensuring shoppers will not be on the hook for the price of constructing the plant.
Kairos and Google will bear the monetary danger related to constructing the first-of-a-kind undertaking, the businesses mentioned. TVA, in the meantime, is offering the income stream the plant might want to function by means of the ability buy settlement.
“We think this solves the problem of making sure that consumers don’t carry that first-of-a-kind cost and risk,” TVA CEO Don Moul advised CNBC. “But it also allows innovators like Kairos Power and thought leaders like Google to bring this to market.”
Hermes 2 is anticipated to begin working at Oak Ridge, Tennessee, in 2030. Kairos obtained a development allow for the reactor from the Nuclear Regulatory Commission in November 2024. It might want to apply for an working license with the NRC earlier than the plant can begin operations.
TVA declined to reveal how a lot it is going to pay for electrical energy from Hermes 2 when requested by CNBC. Kairos declined to reveal the estimated price of the plant.
Building nuclear once more
The U.S. has principally stopped constructing nuclear vegetation as a result of large price overruns and delays that plague the trade. The final two reactors built in the U.S. at Plant Vogtle in Georgia price $18 billion greater than anticipated and began operations seven years not on time in 2023 and 2024. The undertaking’s issues contributed to the chapter of trade stalwart Westinghouse.
Startups like Kairos consider their smaller vegetation will show to be sooner and extra reasonably priced to construct than giant reactors like these at Vogtle, serving to to usher in a brand new period of nuclear development within the U.S. Despite these guarantees, utilities have been reluctant to decide to small advanced reactors over issues concerning the preliminary price ticket.
Technology corporations like Google, in the meantime, are investing in advanced nuclear as a result of they need dependable, carbon-free energy to satisfy the demand from synthetic intelligence whereas adhering to their environmental objectives. Google has positioned orders with Kairos for reactors totaling 500 megawatts of energy which might be focused to come back on-line by means of 2035.

“We specifically want to help commercialize,” Amanda Peterson Corio, Google’s world head of knowledge middle vitality, advised CNBC. “We want to see how can we take this from something small to something bigger that we can deploy at scale. That’s really what the Hermes 2 project is doing.”
One of Kairos’ objectives with Hermes 2 is to create a standardized reactor design which is able to assist reduce the price of future deployments, CEO Mike Laufer advised CNBC. Kairos may even develop the availability and manufacturing infrastructure wanted to launch at scale by means of the development of Hermes 2, he mentioned.
“We’d be ready to deploy multiple reactors in series at the same sites in a very cost-efficient way to deliver that power at affordable rates in the not too distant future,” Laufer mentioned. Kairos and Google are exploring choices on the place future vegetation will likely be deployed, he mentioned.
Oak Ridge, TVA nuke hub
Kairos’ expertise is totally different than the reactors at the moment working within the U.S. Its reactor design makes use of liquid salt because the coolant somewhat than mild water, which permits the plant to function at close to atmospheric strain. This means Kairos can use thinner and cheaper supplies as a result of the reactor is just not below excessive strain. Operating at low strain additionally has security benefits.
The 50-megawatt plant can also be a lot smaller than the reactors within the present U.S. fleet that common 1,000 megawatts in output, which is sufficient to energy a complete metropolis. The Kairos reactor will improve its output to 75 megawatts when it launches on a business scale, Laufer mentioned.
Hermes 2 will likely be deployed close to Oak Ridge National Laboratory, which has an extended historical past in nuclear science courting again to the Manhattan Project throughout World War II. TVA was established by Congress through the Great Depression as a public company to affect the area. The utility stays owned by the federal authorities.
“This kind of sets the stage for east Tennessee to really be what we see as a regional hub for innovation for nuclear construction and operation, and that’s going to be valuable for the nation as well,” Laufer mentioned.
