artificial intelligence electricity demand is multiplying of data centers, and with it, the interest of large technology companies in energy sources capable of keeping them running 24 hours a day. Amazon has gone one step further with Cascade, a new generation nuclear plant that aims to change the way the company powers its digital infrastructure. It is not a simple energy installation: it is the symbol of an ambition that combines autonomy and energy security in the midst of the AI revolution.
This industry is not only transforming the labor marketis also testing the global energy infrastructure. Large data centers that process millions of operations per second need a constant supply, and renewable sources, although clean, do not always guarantee that stability. Hence, nuclear energy is once again gaining prominence as a strong and carbon-free option. For companies like Amazon, the challenge is no longer just to innovate in algorithms, but to guarantee the energy that keeps them running without interruptions.
What we know about the plant. Named Cascade Advanced Energy Facility, Amazon’s new nuclear plant will be built near Richland, Washington state. Over there, the company will work with Energy Northwest and X-energyresponsible for the design of the reactors. Cascade will be located near the current Columbia Generating Station. Amazon defines it as a key step to reduce emissions and provide constant electricity to the network that supports its global digital infrastructure.
Cascade will rely on X-energy’s Xe-100 design, a next-generation modular reactor designed to be more efficient and safer than conventional models. The first phase adds 320 MW with four SMRs, and the plant can be expanded by up to 12 units to reach 960 MW. The scheme includes three 320 MW sections that will occupy only a few blocks. This modularity is one of the keys to the project: it allows production to be scaled according to demand and takes up much less space than a classic nuclear power plant, which can extend over more than 2.5 km².
A different ‘campus’. Unlike traditional power plants, the Cascade plant will be organized as a small energy campus. Its modules will include reactor buildings, service areas, turbines, condensers and a space for temporary fuel storage. The complex, according to X-energy projections, will occupy a compact area that is more similar to an industrial estate than a classic nuclear facility. This modular approach allows you to build in phases and maintain operation without major interruptions in future expansions.


Amazon’s schedule for Cascade moves forward in stages. The company plans to begin construction before the end of this decade and reach the operational phase in the 2030s. These are tentative goals, which depend on both the licensing process and the industrial development of the Xe-100 reactors.


A project that needs labor. According to Amazon, Cascade will create more than 1,000 construction jobs and at least 100 permanent positions in areas such as engineering and operations. In parallel, Columbia Basin College will open the Energy Learning Center, funded by the Department of Energy, with a simulator that reproduces the control of the Xe-100 reactor. This program will allow young people in the region to access qualified jobs and reinforce Washington’s role in the transition to clean energy.


More initiatives. Amazon is not the only technology company that sees nuclear energy as an ally for artificial intelligence. Microsoft has signed an agreement to reopen a plant and, in parallel, is studying long-term contracts with nuclear fusion projects, still in the experimental phase. Google, for its part, collaborates with companies in the sector to integrate small modular reactors (SMR) into its supply network. Although the paths differ, they all share the same challenge: powering a digital infrastructure that consumes more electricity every year.
Although Amazon has shared many of the details of Cascade, the project is still in an early phase. There are no definitive dates for the start of construction or for the commissioning of the reactors. It has also not been specified what volume of energy will be allocated to its data centers and what part will be integrated into the local network. Everything indicates that the coming years will be decisive in testing whether modular nuclear energy can respond to the pace demanded by artificial intelligence.
