Georgia Power, primary owner of the Vogtle nuclear plant, announced last Friday that it will pay $413 million to settle a lawsuit brought against it last year by plant co-owner Oglethorpe Power Corporation.

Both Oglethorpe Power Corporation and the Municipal Electric Authority of Georgia (MEAG), two co-owners of the Vogtle nuclear plant, have filed lawsuits against Southern Company subsidiary Georgia Power, the facility’s primary owner.

Oglethorpe and MEAG are 30 percent and 22.7 percent owners, respectively, of Vogtle. Georgia Power holds a 45.7 percent share. (Dalton Utilities, which owns 1.6 percent of the plant, is not involved in the suits.)

The total bill for the reactor expansion project at the Vogtle nuclear plant in Georgia is now expected to exceed $30 billion, according to the Associated Press. The original price tag for the two Westinghouse AP1000 units was $14 billion.
