Amazon announced in mid-October 2025 and other times that the new small modular reactor agreements are part of Amazon’s plan to transition to carbon-free energy. As Amazon continues on their path to net-zero carbon, they recently announced that they matched all of the electricity consumed by our global operations with 100% renewable energy—seven years ahead of our 2030 goal.
As the energy needs of our business and customers continue to grow, we’re continuing to invest in renewables while also finding additional sources of carbon-free energy that can both help power our operations and bring new sources of energy to the grid.
Nuclear power is one part of that mix—it can be brought online at scale, and has a decades-long record of providing a reliable source of safe carbon-free energy for communities around the world.

Today, in Amazon announcing that they have signed three new agreements to support the development of nuclear energy projects—including enabling the construction of several new Small Modular Reactors (SMRs). SMRs are an advanced kind of nuclear reactor with a smaller physical footprint, allowing them to be built closer to the grid. They also have faster build times than traditional reactors, allowing them to come online sooner.
Jassy explains how sustainability initiatives are embedded into Amazon’s entire business:
“Nuclear is a safe source of carbon-free energy that can help power our operations and meet the growing demands of our customers, while helping us progress toward our Climate Pledge commitment to be net-zero carbon across our operations by 2040,” said Matt Garman, CEO of Amazon Web Services (AWS):
“One of the fastest ways to address climate change is by transitioning our society to carbon-free energy sources, and nuclear energy is both carbon-free and able to scale—which is why it’s an important area of investment for Amazon. Our agreements will encourage the construction of new nuclear technologies that will generate energy for decades to come.”
Developing new sources of nuclear power with Small Modular Reactors
In Washington, Amazon's agreement with Energy Northwest, a consortium of state public utilities, will enable the development of four advanced SMRs. The reactors will be constructed, owned and operated by Energy Northwest, and are expected to generate roughly 320 megawatts (MW) of capacity for the first phase of the project, with the option to increase to 960 MW total—enough to power the equivalent of more than 770,000 U.S. homes. These projects will help meet the forecasted energy needs of the Pacific Northwest beginning in the early 2030s.

Amazon is also making an investment in X-energy, a leading developer of next-generation SMR reactors and fuel, and X-energy’s advanced nuclear reactor design will be used in the Energy Northwest project. The investment includes manufacturing capacity to develop the SMR equipment to support more than five gigawatts of new nuclear energy projects utilizing X-energy’s technology.
In Virginia, Amazon has signed an agreement with utility company Dominion Energy to explore the development of an SMR project near Dominion’s existing North Anna nuclear power station. This will bring at least 300 megawatts of power to the Virginia region, where Dominion projects that power demands will increase by 85% over the next 15 years.
Helping preserve existing nuclear reactors
Amazon also previously signed an agreement to co-locate a data-center facility next to the Talen Energy’s nuclear facility in Pennsylvania, which will directly power their data centers with carbon-free energy, and helps preserve this existing reactor.

Investing in local communities
In addition to creating and preserving sources of carbon-free energy, Amazon investments in nuclear-energy projects are expected to provide an economic boost for the local communities in which they reside. Amazon's agreement with Energy Northwest is expected to support up to 1,000 temporary construction jobs and as many as 100+ permanent jobs once the SMR project is fully operational, according to Energy Northwest.
In Pennsylvania, we’re building a data center campus as part of Amazon's investment in Talen Energy, and that project will create construction jobs and bring upgrades to local utility infrastructure. And our investment will also help preserve the 900 local jobs that are already there to keep the facility up and running, according to Talen Energy.
How Amazon is also harnessing solar energy, batteries, and AI to help decarbonize the grid
Artificial Intelligence is helping solar-plus-storage projects provide power even when the sun isn’t shining. As Amazon continues to create and preserve these sources of safe, carbon-free energy, Amazon is addressing the future energy demands of Amazon's business, making progress toward their sustainability goals, and supporting local communities across the country. Amazons plan to continue to share updates about their progress, and the general public can learn more about Amazon's carbon-free energy efforts.
