Amazon backs 960-megawatt plant using X-energy SMRs near Terre Haute

Business Oct 19, 2026

Amazon is backing a new 960-megawatt nuclear plant at a former coal power site near Terre Haute, Indiana.

The project uses 12 small modular reactors from X-energy and will be run by American Electric Power (AEP).

Amazon will be the first to use electricity from the plant, showing how serious it is about cleaner energy.

Amazon, X-energy aim 5GW by 2039

This follows Amazon's $700 million investment in X-energy in October 2024.

Together, they aim to build 5 gigawatts of new nuclear capacity in the US by 2039, enough to power both public grids and Amazon's data centers.

Investors are excited too: X-energy's stock jumped 10% after the news.

Still, everything depends on getting permits for another project in Texas before these big plans can really take off.
