ATLANTA, June 7, 2021 /PRNewswire/ -- Georgia Power announced today that plant equipment for Vogtle Unit 4 is now energized, or permanently powered, which is needed to perform all subsequent testing for the unit at the Vogtle 3 & 4 nuclear expansion project.

With plant equipment previously running on temporary construction power, the achievement of initial energization marks another step towards system operations as Unit 4 continues to progress through its testing phase.

Earlier this year, the project team started the integrated flush testing process on Unit 4, which pushes water through the permanent plant system piping that feeds into the reactor vessel and reactor coolant loops. Integrated flush represents a critical step as the process is key to helping ensure the safe startup of Unit 4 and initiated the start of extensive testing ahead for the unit's systems.

Carbon-free energy source
The new Vogtle units are an essential part of Georgia Power's commitment to deliver safe, clean, reliable and affordable energy for customers and play a significant role in supporting Southern Company's goal of net-zero carbon emissions by 2050.

Once operating, the two new units at Plant Vogtle will be able to power more than 500,000 homes and businesses. A diverse fuel mix, including nuclear, is also essential to maintaining a reliable and affordable energy infrastructure that attracts new investment, supports economic growth and creates jobs.

With more than 7,000 workers on site, and more than 800 permanent jobs available once the units begin operating, Vogtle 3 & 4 is currently the largest jobs-producing construction project in the state of Georgia.
