Vogtle Units 3 and 4 (2009–2024)
Georgia Power began building two large reactors at Plant Vogtle, each about 1,100 megawatts. The project ran roughly seven years late and cost more than $30 billion, over double the original estimate.
The reactors finally reached full power in 2023 and 2024, the first new U.S. units built from scratch in decades.
The overruns scared utilities off large custom reactors and pushed the industry toward smaller, standardized designs.
Vogtle is the cautionary tale Last Energy sells against: build small and identical in a factory instead of huge and bespoke on-site.
