Kairos Power and Google have entered into a Master Plant Development Agreement to build a series of advanced nuclear power plants that will deliver up to 500 MW of clean energy by 2035. The project aims to support Google’s data centers with 24/7 carbon-free electricity, helping the tech giant meet its ambitious net zero goals. The first deployment is planned for 2030, with Kairos Power overseeing the design, construction, and operation of the reactors under Power Purchase Agreements (PPAs).
Each reactor will be part of Kairos Power’s iterative development strategy, allowing the company to optimize its technology and accelerate commercialization. The agreement includes multiple deployment sites across the U.S., designed to generate clean electricity and provide ancillary services. Google’s long-term commitment provides Kairos Power with the opportunity to establish confidence in its ability to deliver on a large scale.
• 500 MW of advanced nuclear power to be deployed by 2035
• First plant operational by 2030, supporting Google’s net zero goals
• Kairos Power to sell energy under long-term Power Purchase Agreements
• Agreement includes milestone-based accountability and multi-plant deployments
• Google has committed to more than 14 GW of clean energy since 2010
Kairos Power, founded in 2016 and headquartered in Alameda, California, is focused on revolutionizing nuclear energy through its fluoride salt-cooled high-temperature reactor (KP-FHR). This innovative reactor design utilizes molten salt as a coolant and TRISO fuel, which enhances safety and efficiency by allowing the reactor to operate at lower pressures and higher temperatures compared to traditional water-cooled reactors. In December 2023, Kairos Power secured a construction permit for its demonstration reactor, Hermes, in Tennessee, marking the first approval for a non-water-cooled reactor in the U.S. in over 50 years. The company has received significant backing, including up to $303 million from the U.S. Department of Energy under the Advanced Reactor Demonstration Program to support the Hermes project. Kairos Power aims to deliver clean, affordable energy that is competitive with natural gas, contributing to the transition toward sustainable energy solutions.
Since 2010, Google has signed more than 115 agreements, securing over 14 GW of clean energy capacity. The deal with Kairos Power marks Google’s first major foray into nuclear energy, complementing its existing renewable portfolio and driving progress toward decarbonization.
“Our partnership with Google will help Kairos Power quickly advance down the learning curve as we work toward cost and schedule certainty for our commercial product,” said Mike Laufer, CEO of Kairos Power.
