Plant Vogtle near Waynesboro, Georgia, stands as the largest nuclear power plant in the United States, with four reactors delivering a combined capacity of 4,536 megawatts. Units 3 and 4, the first AP1000 reactors built in the country, entered commercial operation in July 2023 and April 2024, joining two older units that have run since the 1980s.
Together the four units are expected to generate more than 30 million megawatt-hours of electricity annually, enough to serve roughly 2 million homes, according to Georgia Power. The plant is jointly owned by Georgia Power, which holds a 45.7 percent stake, along with Oglethorpe Power Corporation at 30 percent, the Municipal Electric Authority of Georgia at 22.7 percent, and Dalton Utilities at 1.6 percent.
Plant Vogtle now anchors a growing share of Georgia's generation mix as the state absorbs rising electricity demand from population growth and a wave of data center construction across the Atlanta metro region and beyond. Nuclear power accounted for roughly 34.7 percent of Georgia's electricity generation mix in 2025, trailing only natural gas among the state's fuel sources.
Georgia's Public Service Commission continues to oversee rate matters tied to the plant's construction costs as part of its ongoing regulatory review of Georgia Power's operations.
