Plant Vogtle near Waynesboro, Georgia, remains the largest nuclear power plant in the United States, with a generating capacity of 4,536 megawatts after Units 3 and 4 entered service. The facility, operated by Georgia Power, anchors the state baseload generation and continues to shape utility planning across Georgia.
Georgia Power reached an agreement with regulatory staff to hold base power rates steady through the end of 2028, a commitment that follows years of debate over the cost of completing the Vogtle expansion. Customer bills could still move in 2026 due to fuel and other adjustments outside base rates, but the agreement freezes the base component for the next several years.
The plant role takes on added weight as the state plans for sharp load growth. The Public Service Commission approved a broad expansion of Georgia Power generation fleet that would add capacity exceeding the combined output of Vogtle four reactors within five years, drawing on new natural gas plants, battery storage, and solar. That buildout reflects rising demand driven heavily by data center development across metro Atlanta.
As the most recently completed nuclear project in the country, Vogtle continues to serve as a reference point in national discussions about nuclear construction cost and schedule. Its steady output now provides a large share of Georgia carbon-free electricity, and its performance is closely tracked by utilities weighing similar large-scale nuclear investments elsewhere in the United States.
