The following is a Georgia Power news release:

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 toward 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.
