Plant Vogtle, operated by Atlanta-based Georgia Power, supplies a large share of the state's electricity following the completion of its two newest reactors. The Vogtle and Hatch nuclear facilities together provide about 29 percent of the electricity used in Georgia, and Vogtle Units 3 and 4, alongside the older Units 1 and 2, power more than 1 million homes and businesses.
Unit 3 entered commercial operation in July 2023 and Unit 4 in April 2024, making Vogtle the largest generator of clean electricity in the United States at completion. Within Georgia Power's generation mix, nuclear represented 34 percent of kilowatt-hours produced in 2024, with natural gas at 44 percent, coal at 19 percent, and hydro and other sources at 3 percent.
The expansion was completed at a final cost of roughly $36.8 billion, and the project remains a reference point in debates over the economics of new nuclear construction in the United States. Georgia Power, headquartered in Atlanta in Fulton County, continues to operate the reactors as long-term baseload capacity. The plant's output figures illustrate the scale of generation that a completed two-unit expansion adds to a state grid serving growing electricity demand.
