Plant Vogtle in Georgia remains the largest nuclear power station in the United States and a central source of electricity for metro Atlanta and the wider state. With the additions of Units 3 and 4, the plant reached a total capacity of about 4,536 megawatts, and each of the two new reactors produces roughly 1,100 megawatts.

The expansion completed a long construction effort. Unit 3 entered commercial operation in July 2023 and Unit 4 in April 2024, making the site the largest generator of clean electricity in the country. Together with the older Units 1 and 2, the four reactors power more than 1 million homes and businesses across Georgia Power's service territory, which includes Fulton, Cobb, Gwinnett, and the surrounding metro Atlanta counties.

Ownership is shared among several Georgia utilities. Georgia Power holds 45.7 percent, Oglethorpe Power Corporation 30 percent, the Municipal Electric Authority of Georgia 22.7 percent, and Dalton Utilities 1.6 percent. Southern Nuclear operates the plant on behalf of the co-owners.

As the newest large reactors to enter service in the United States, Units 3 and 4 give Georgia a long-lived, high-output source of baseload power at a time when electricity demand is climbing across the Southeast. The plant's steady output supports grid reliability for a region seeing rapid growth in data centers and industrial load.
