We have a vision of a clean energy future and every day, we put it in motion.
Georgia Power’s Plant Vogtle Units 3 and 4 will be the first newly constructed nuclear units built in the United States in more than three decades. With the completion of Unit 3, we are providing customers and communities with carbon-free nuclear energy.
Operating 24/7/365, nuclear energy facilities produce more than half of all U.S. carbon-free electricity. Plant Vogtle will play an essential role in supporting Southern Company’s goal of net zero greenhouse gas emissions by 2050. When Unit 4 is complete, Plant Vogtle will be the largest carbon-free generation asset in the country.
With the nation’s first new nuclear reactor in thirty years having come online, an increasing number of experts view carbon-free nuclear energy as an “irreplaceable” part of the solution to climate change.Read More
A diverse energy portfolio, including carbon-free nuclear, is essential to maintaining a reliable and affordable energy infrastructure that:
On February 14, 2024, Unit 4 safely reached initial criticality, a key step during the startup testing sequence demonstrating that operators have safely started the nuclear reaction inside the second reactor. A reactor achieves criticality when the nuclear fission reaction becomes self-sustaining. Achieving initial criticality is necessary to continue the startup of the unit in order to generate sufficient heat for the production of electricity. Vogtle Unit 4 continues with startup testing, demonstrating the integrated operation of the primary coolant system and steam supply system at design temperature and pressure with fuel inside the reactor. These tests are designed to ensure all systems are operating together and to validate operating procedures prior to declaration of commercial operation.
Now that the Unit 4 reactor has reached criticality, operators will continue to raise the power to support synchronizing the generator to the electric grid to begin producing electricity. Then, operators will continue increasing power through multiple steps, ultimately raising power to 100%. Vogtle Unit 3 entered commercial operation on July 31, 2023, and is providing safe, reliable, emission-free energy to Georgia today. The in-service date for Unit 4 is projected during the second quarter of 2024.
The Vogtle Electric Generating Plant is jointly owned by Georgia Power (45.7%), Oglethorpe Power Corporation (30%), Municipal Electric Authority of Georgia (22.7%) and Dalton Utilities (1.6%).
