Georgia Power Co. will postpone efforts to increase the certified cost of Plant Vogtle’s nuclear expansion until the first of two new reactors has been completed.
The company, which owns a 45.7 percent stake in the project, was authorized by Georgia’s Public Service Commission to spend $6.11 billion. Company officials later asked that the authorized amount be increased by an additional $737 million.
In a stipulation filed with the commission this week, the company said actual costs “may not be fully ascertainable” because of unresolved litigation with contractors and other variables.
“For these reasons, the Public Interest Advocacy staff and the company agree that the request to amend the certification is not ripe for consideration,” the stipulation said.
Further cost amendments will be held in abeyance until the plant’s Unit 3 reactor has been completed, by which time officials hope to have a more accurate assessment of the project’s total cost.
Under the most recent completion forecasts, the Westinghouse AP-1000 reactors under construction at the Burke County site are scheduled to go online in the fourth quarters of 2017 and 2018 for units 3 and 4, respectively.
Other co-owners of the project are Oglethorpe Power (30 percent), Municipal Electric Authority of Georgia (22.7 percent) and Dalton Utilities (1 percent).
