l佐治亚州Power需要Bechtel领导的项目团队的新核电单位的第一个服务截止日期，比ESS超过一年。

及时完成符合2021年11月的Vogtle Unit 3的商业运营日期（COD）所需的工作，这将代表这项长期困难的项目的重要，几乎奇特的转变。但是，根据最近提交给佐治亚州公共服务委员会的证词，这不是项目监视者认为会发生的事情。

的确，建造两个新核电单元的建设七半以上，自项目成立以来11年，最新的修订时间表可能与其前任一样不现实。

“自2009年启动该项目以来，所有[综合项目时间表]迭代均过于激进和无法实现。”testimony11月24日由史蒂芬·罗特（Steven Roetger）和威廉·雅各布斯（William Jacobs）提交，该项目监视器为佐治亚州PSC工作。

“The history of the project has shown that the CODs projected by SNC (Southern Nuclear Company) have ultimately been required to be delayed,” the monitors continued, concluding that “there still exists a high likelihood of the COD not being achievable.”

COVID-19的进度放慢了。根据项目所有者佐治亚州项目的说法，截至10月20日，有1000多名工人的测试阳性。反过来，这些阳性案例需要至少14天隔离约6,600名工人。总体而言，该公司估计与共同相关的成本影响在1.5亿至2.5亿美元之间。

尽管遇到了障碍，但佐治亚州的权力仍然公开承诺其时间表，如10月所指出testimonyjointly submitted by Georgia Power’s David McKinney, senior vice president, and Jeremiah Haswell, director of project oversight.

麦金尼和Haswell作证说,“尽管锅demic continues to impact the project, based on current information and projections, we believe that the project will be able to bring Unit 3 and Unit 4 online by the regulatory-approved in-service dates of November 2021 and November 2022.”

进一步的计划滑点可能会增加第3单元和4扩展的总项目成本。SNC目前估计为171亿美元，滑板可能会增加约20亿美元。唐·格雷斯，Vogtle Monitoring Group的副总裁。

A Different Approach

Both PSC staff monitors and Grace fault the utility’s focus on major milestones rather than percentage of completion, number of finished pre-operational tests and completed work packages.

他们说，专注于完整的系统测试或单元3围护罩的设置无法提供真正的进度衡量。

“We do not believe that the accomplishment of major milestones in isolation is an appropriate way to gauge the overall progress of the project. Metrics including construction percent complete,” argue staff monitors Roetger and Jacobs, and the “… number of preoperational tests completed and number of systems turned over to operations provide a more comprehensive and better indication of the overall status of the project.”

其中一个指标，即关闭工作包的指标，继续挑战承包商。

PSC员工监视指出，截至10月中旬，SNC报告说，Vogtle单元3.沃格特尔3号的开放式工作包3.援引内部佐治亚州电力报告，Roetger和Jacobs进一步指出，要符合时间表，SNC将需要增加两倍多的双倍。目前的每周关闭率约为200至每周450多个，以关闭与热功能测试（HFT）里程碑有关的所有剩余的1,900多个工作包。

Testing should await completion of concrete and steel work, said Grace.

In testimony submitted to the PSC on Nov. 24, Grace criticized SNC’s approach to construction for the continuing delays, asserting that “a primary root cause of poor productivity and production is due to SNC’s strategy of accelerating testing prior to completion of civil work and a greater degree of the bulk construction commodities which then leads to inefficient and costly execution of construction.”

格蕾丝继续说：“相反，SNC错误地得出结论，与正常行业实践的偏差将既要缩短时间表，又缩短时间表（b）允许在估计的TPC（总项目成本）内完成该项目。

格蕾丝进一步断言，SNC有时会采取替代措施来实现一个主要的里程碑。

Wire pulls were a concern. “VMG believes that the extensive use of ‘partial releases for test’ … in many cases to support a nearer-term schedule milestone, can lead to pulling and terminating single cables versus doing bulk pulls of all cables,” resulting in multiple cable runs along a single route, requiring more worker hours.

此外，格蕾丝（Grace）表示，他对相关项目工作时间数据的分析使他相信这种方法可能对电缆造成了损坏，这需要与更换电缆和重新开放的密封墙穿透相关的重新工作。

纳税人的危险

就公用事业的一个部门而言，佐治亚州的权力和高管在PSC证明了他们所采用的建筑方法，这是实现迫在眉睫的认证运营日期截止日期的最佳机会。

“Project leadership acknowledges that our expected case for Unit 3 is challenging and Unit 4’s site work plan is aggressive,” stated SNC CEO Stephen Kuczynski, and Aaron Abramovitz, vice president of Plant Vogtle.

But the leaders “continue to believe that working toward a challenging schedule is necessary to maintain the focus and drive of the project, identify and mitigate risks early, and ultimately support the project’s objective of meeting the regulatory-approved in-service dates for Units 3 and 4.”

无论哪种方式，当前的商业运营日期分别比2016年和2017年的最初目标晚五年。佐治亚力量的纳税人肯定会感受到总成本的增加。新利18备用官网登录

见证由PSC财务总监Tom Newsome领导的一组财务分析师团队提交了这一点。

该小组指出，一旦新单元成为运营，佐治亚州的电力可能会要求在其利率基础上增加约81亿美元，或者比认证时假设的44亿美元高出约83％。

正如Newsome团队总结的那样：“总而言之，由于延迟和成本超支，纳税人在单位开始提供服务之前和之后的支付费用要大得多。”

Notably, once units are online, a prudency review by the Georgia PSC could disallow certain costs, reducing the amount Georgia Power could charge its customers.
