Georgia's Second New Nuclear Reactor Achieves Initial Criticality

The milestone at Plant Vogtle's Unit 4 is a significant step towards carbon-free electricity production, with commercial operations expected in Q2 2024.

  • Plant Vogtle's Unit 4 in Georgia has reached initial criticality, marking a key phase in its journey to generate carbon-free electricity.
  • The reactor is now undergoing startup testing, with full power generation and grid synchronization anticipated between April and June 2024.
  • Unit 4's completion has been delayed due to issues with a cooling system, but it is now on track for Q2 2024 commercial operations.
  • Once operational, Units 3 and 4 will collectively power 1 million homes without emitting carbon, despite cost overruns and delays.
  • Georgia Power's customers will see a rate increase to cover the $7.56 billion in remaining costs for Vogtle, with the total project nearing $35 billion.
