Plagued by Grim Challenges, Vogtle Nuclear Expansion Lags Behind Schedule, Says Oversight Consultant

December 6, 2018

The two-unit Vogtle expansion in Georgia faces major challenges that are poised to derail its schedule and ramp up costs—and the project is already behind schedule, a consulting firm tasked with construction oversight of the project told regulators.

In revealing testimony filed with the Georgia Public Service Commission’s (PSC’s) public interest advocacy staff on November 30, Donald Grace, vice president of engineering for Cost Plus Technology—Nuclear Construction Oversight (CPT), noted that the total construction cost—which includes all owner-shared costs but excludes financing costs—to complete the two Vogtle units by the scheduled November 2021/2022 timeframe is $ 17.1 billion. Only about 60% of the project is complete, he said.

Meanwhile, the project faces several potentially debilitating challenges that could cause delays and drive up costs. Foremost among them are labor shortages. While Georgia Power noted about 7,000 workers were onsite as of December 4, according to Grace, “Obtaining sufficient numbers of qualified craft labor pipe fitters and electricians are necessary to support the planned installation rate for bulk piping and electrical commodities.”…

FPL Halfway Through 600-MW Solar Power Expansion

Florida Power & Light (FPL), which recently sustained a blow to its nuclear expansion plans, on October 19 said it’s about halfway through an ambitious plan to add eight new solar plants in the state by early 2018, as it continues to increase its photovoltaic (PV) generation capacity as part of a larger strategy to install more than 10 million solar panels in its service territory by 2023.

FPL already has installed about 1.25 million solar panels at the eight new plants, with another 1.25 million to go. It’s the utility’s largest one-year solar expansion, surpassing the company’s installation of 1 million panels at three solar plants in 2016. FPL said construction at the sites at its peak employed more than 1,000 workers.

FPL President and CEO Eric Silagy on October 19 said the company is “investing nearly $ 1 billion to grow solar in Florida this year alone.” Silagy, visiting the Barefoot Bay Solar Energy Center in Brevard County on Thursday as part of a tour with local officials, said: “Together, these eight new plants are projected to generate an estimated net lifetime savings of more than $ 100 million for our customers, over and above the cost of construction.”…

CAISO Expansion, 100% Zero-Carbon Bids Flatline, But Bills for Energy Storage, DERs Thrive

California’s legislature last week wrapped up its 2017 session without authorizing the broad expansion of the California Independent System Operator (CAISO) into other Western states or passing a zero-carbon bill, which would have put the state on a path to 100% clean energy by 2045. It did, however, succeed in passing bills to encourage development of energy storage and distributed energy resources to reduce its reliance on gas-fired generation in light of the Aliso Canyon debacle.

A Freeze on CAISO Regionalization

CAISO and a number of participants within the Western Interconnection have been exploring the creation of a more fully integrated regional electricity market that would be managed by a single system operator and include day-ahead and real-time markets, but the measure will now need to be revived next year.

As some of the initiative’s proponents point out, power within the Western Interconnection is managed by 38 separate balancing authorities in the U.S., Canada, and Mexico. While all balancing authorities, including CAISO, are part of a synchronized grid, each authority is responsible for its own territorial supply and demand balance.…

Georgia PSC Signals Support Continuing Vogtle Expansion

In two actions on August 15, the Georgia Public Service Commission (PSC) signaled its support for the Vogtle nuclear expansion project, provided it can be done economically,

Georgia Power must show revised cost and schedule estimates to finish the costly Vogtle nuclear expansion as well as indicate whether it intends to finish the much-delayed construction project in its next construction monitoring report, which is due on August 31, one motion requires.

The PSC voted 4–1 on the motion put forth by Commission Chairman Stan Wise. The motion also requires Georgia Power to address whether the commission should approve revisions to project costs and schedule.

“This vote today sends a message to the Company, the Company’s partners, ratepayers, and Wall Street that the Commission continues to be supportive of this project provided it can be done economically,” Chairman Wise said in a statement. “This information will help us in deciding the appropriateness of whether this project should go forward or not go forward.”…

Xcel Moves Forward With Wind Power Expansion

Xcel Energy plans to add about 1,550 MW of wind power to its portfolio in the Upper Midwest with the addition of seven wind farms expected to be operational by year-end 2020. The additions are among 11 new wind farms announced over the past year by Xcel in seven states that would add a total of 3,380 MW to the company’s system. The company said the expansion would increase its wind portfolio to about 35% of its energy mix by 2021.

The Midwest projects, sited in Minnesota, North and South Dakota and Iowa, would increase Xcel’s regional wind output by about 70%, the company said. The Minnesota Public Utilities Commission approved the proposal July 6; the North Dakota Public Service Commission said it would review the plan later this year. Those states, unlike some others, require Xcel to seek state approval to add resources, according to Lisa Kiava, a senior media relations person in Xcel’s Minneapolis, Minn., office. Xcel said the projects would likely run for 25 years.…

Expansion Joint Bellows Rupture Forces D.C. Cook Nuclear Plant Offline

Indiana Michigan Power—a subsidiary of American Electric Power (AEP)—reported that Unit 2 of its Donald C. Cook Nuclear Plant in Bridgman, Mich., was forced offline on July 6 due to an expansion joint bellows rupture on the unit’s moisture separator reheater.

Although no one was in the area at the time and there were no injuries, an adjacent turbine building exterior wall was damaged when the roughly 48-inch-diameter bellows burst. The component is part of the plant’s secondary steam system, providing nonradioactive steam to the low-pressure turbine.

An Unusual Event, the lowest level alert on the Nuclear Regulatory Commission’s (NRC’s) emergency response scale, was declared at 12:50 a.m. due to the unanticipated incident. The event was terminated at 2:07 a.m. The company said all appropriate notifications to local, state, and federal officials were made.

Unit 2 was shut down manually, with no impact to public health and safety. Unit 1 was not involved in the event and remains in operation at full power.…
