X-energy's flagship commercial deployment — four Xe-100 units at the Cascade Advanced Energy Facility near the Columbia Generating Station in Richland, Washington. Amazon led X-energy's $500 million Series C-1 in October 2024 and signed a binding agreement for up to 5 GW of nuclear power by 2039. Construction expected to begin in 2026 targeting operational in 2030. The facility is expandable to 12 units and 960 MW. X-energy went public on Nasdaq (XE) in April 2026 raising $1.02 billion — the largest nuclear IPO in history.
