The mission to develop the two-unit Plant Vogtle nuclear energy station in Georgia with two new AP1000 reactors was has suffered debilitating delays and mounting prices.

The mission is owned by 4 companions: Southern Co. subsidiary Georgia Power (45.7%), Oglethorpe Power Corp. (OPC, 30%), Municipal Electric Authority of Georgia (MEAG Power, 22.7%), and Dalton Utilities (1.6%).

Units 1 and a couple of at Plant Vogtle, which is positioned about 25 miles south of Augusta, Georgia, encompass Westinghouse four-loop pressurized water reactors (PWRs) rated at 1,109 and 1,127 MW respectively. Unit 1 started business operation in 1987; Unit 2 adopted in 1989. Original estimates for Vogtle reactors 1 and a couple of had been beneath $1 billion every, however remaining prices skyrocketed to almost $9 billion. 

2006: Southern Nuclear, a 1990-established subsidiary of Southern Co. and licensed operator of Plant Vogtle, begins creating the mission. In 2009, a Southern Co. official instructed POWERthat the enlargement would meet rising demand for electrical energy: “Based on the statistical information from the Department of Energy [DOE], 40% of the U.S. inhabitants can be dwelling within the southeastern U.S., and the state of Georgia alone is anticipated to develop by four million folks, by 2030. Over the final 13 years, common residential consumption in Georgia rose roughly 16%. Over the subsequent 15 years, electrical demand on the Georgia Power system is projected to develop 30%,” he mentioned. The official additionally famous a key Southern Co. goal was to maintain its energy profile diversified. The firm filed for an early web site allow (ESP) software in August 2006.

2008–2009: NuStart Energy Development LLC (NuStart), a partnership of 10 energy firms created in 2004 to acquire a mixed building and working license (COL)—utilizing a brand new streamlined licensing course of—and to finish design engineering for the chosen reactor applied sciences, helps Southern Nuclear submit its unique and supplemental COL functions in 2008 and 2009.

April 2008: A consortium comprising CB&I Stone & Webster and Westinghouse, maker of the AP1000 reactors, indicators engineering, procurement, and building (EPC) contracts with the utility house owners. The EPC agreements—the primary of their type signed for brand new U.S. nuclear plant building in three many years—outlined a “assured substantial completion date” of April 2016 and April 2017 for Vogtle Units three and four, respectively. (The group signed related offers with V.C. Summer plant house owners for Units 2 and three at that web site in South Carolina.) Significantly, the agreements subjected the consortium to a variety of liquidated damages provisions, if it didn’t meet these deadlines.

August 2008: Southern Co. and utility companions apply to obtain a federal mortgage assure. Total prices for the mission are estimated at $14.three billion.

March 2009: Construction of the 2 AP1000 reactors, every 1.1 GW, is authorized by the Georgia Public Service Commission (PSC). The PSC adopts a movement permitting Georgia Power to get better the price of financing the plant throughout building. Both entities will collectively develop mechanisms to offer shared threat safety to taxpayers from important value overruns. In addition, the Georgia Senate voted to permit the corporate to get better its financing prices throughout building of the reactors, thereby saving prospects about $300 million over time. The PSC settlement set Georgia Power’s portion of the licensed value of the brand new items at almost $6.5 billion.

August 2009: The Nuclear Regulatory Commission (NRC) approves the ESP and restricted work authorization (LWA) for the first-of-their-kind reactors.

February 2010: The DOE conditionally gives Southern Co. and companions a complete $eight.33 billion in mortgage ensures.

June 2011: A PSC-hired unbiased building monitor testifies that the mission is 2 months delayed. Just a few months later, it falls to 5 months behind…
