There were more than 5,000 workers involved in building the Vogtle 3 and 4 nuclear units in Georgia, during the fourth quarter of 2014, Southern (NYSE:SO) said in one of its latest online progress reports on the project.
When completed, the Vogtle station will be the only four-reactor nuclear plant in the United States. The Palo Verde nuclear complex in Arizona, which is owned by Pinnacle West Capital (NYSE:PNW) utility Arizona Public Service (APS) has three units.
Vogtle planners are also working on the integration issues at the complex. Southern has already been working on integration on issues like emergency planning and security, officials said during the fourth quarter video.
Workers recently completed erecting the Vogtle 3 cooling tower, which is 600 feet high.
Operation of Vogtle Units 3 and 4 are expected in late 2017 and 2018 respectively. Each unit is expected to generate more than 1,100 MW.
Southern subsidiary Georgia Power is the largest single stakeholder at 45.7%. Other co-owners include Oglethorpe Power, the Municipal Electric Authority of Georgia (MEAG Power) and Dalton Utilities.
The transmission system is being built on site. This includes construction of a 500-kV switchyard.
Like the ongoing SCANA (NYSE:SCG) V.C. Summer construction project for Units 2 and 3 in South Carolina, the Southern group is using the Westinghouse Electric AP 1000 reactor design. The Vogtle project is also using a vendor team led by Chicago Bridge & Iron (NYSE:CBI).
The Southern group is also using a Department of Energy (DOE) loan guarantee to help with the costs for Vogtle Units 3 and 4.
