Entergy Gives Palisades Nuclear Plant Five More Years to Run

September 28, 2017
| No Comments
| Industry News

Entergy Corp. will keep the Palisades nuclear power plant in Covert, Michigan, open until the spring of 2022, owing to a shortfall in recovery granted to Consumers Energy by state regulators.

In a bid to actively exit the merchant nuclear power business, investor-owned Entergy had decided to shutter the 798-MW plant by October 1, 2018.  “Market conditions have changed substantially, and more economic alternatives are now available to provide reliable power to the region,” it said when it announced its decision about a year ago. 

The decision came as a surprise because Entergy has a power purchase agreement with Consumers Energy—Michigan’s largest utility and the principal subsidiary of CMS Energy—which committed the company to buying nearly all the power generated at Palisades through April 2022. Entergy reasoned the plant’s closure could save Consumers’ customers as much as $ 172 million over four years, even after Consumers paid Entergy $ 172 million to terminate the contract.

On September 22, however, the Michigan Public Service Commission granted Consumers a recovery of only $ 136.6 million of the $ 172 million it requested for the buyout of the power purchase agreement. …

Florida Nuclear Plants Will Shut Ahead of Irma

Florida Power & Light (FPL), the largest utility in Florida, said September 7 it would shut down its Turkey Point and St. Lucie nuclear power plants in the hopes of limiting potential damage from Hurricane Irma. The facilities are the only operating nuclear plants in the state.

FPL did not give specific timing for the shutdown, but the Nuclear Regulatory Commission (NRC) said it expects Turkey Point, located south of Miami, will be taken offline the evening of September 8, with the St. Lucie facility on Hutchinson Island, north of West Palm Beach, likely being shut down early on September 9. The effects of Irma, which could be the most-destructive hurricane to ever strike Florida, are expected to be felt in south Florida on Saturday, with conditions worsening throughout the weekend.

The two plants are each about 20 feet above sea level. The plants are protected by concrete and steel barriers, and were further reinforced for protection after the 2011 Fukushima nuclear disaster in Japan, when floodwaters from a tsunami after an earthquake caused multiple meltdowns at the Fukushima Daiichi Nuclear Power Plant.…

UPDATED: SCANA, Santee Cooper Abandon V.C. Summer AP1000 Nuclear Units, Citing High Costs

August 1, 2017

| Industry News

SCANA Corp. and Santee Cooper have ceased construction of Units 2 and 3 at the V.C. Summer Nuclear Station in South Carolina.

The project owners said the decision, prompted by analysis of detailed schedule and cost data, would save customers nearly $ 7 billion. The project, which was about 64% complete, has been in limbo since key contractor Westinghouse filed for bankruptcy in March.

The decision comes just days after Westinghouse’s parent company Toshiba agreed to pay the two project owners nearly $ 2.2 billion to cap its liabilities from the unfinished nuclear project.  Toshiba reached a similar $ 3.7 billion agreement with Southern Co. in June as it seeks to limit its liabilities from the Vogtle project. Both AP1000 nuclear projects are years behind schedule and billions of dollars over budget.

Construction continues at the two Vogtle AP1000 units in Georgia. A project owner, Georgia Power, on July 28 told POWER that it expects to complete the cost-to-complete and schedule assessment by the end of August.…

Toshiba Will Pay $2.2 Billion to Exit Summer Nuclear Project

SCANA Corp. and state-owned utility Santee Cooper on July 27 said Toshiba has agreed to pay nearly $ 2.2 billion to cap its liabilities from the unfinished V.C. Summer nuclear project in South Carolina. Toshiba subsidiary Westinghouse, which was building two nuclear units at the Summer site along with the troubled Vogtle nuclear project in Georgia, filed for bankruptcy in March.

Toshiba reached a similar $ 3.7 billion agreement with Southern Co. in June as it seeks to limit its liabilities from the Vogtle project. Both AP1000 nuclear projects are years behind schedule and billions of dollars over budget.

Decision on Summer’s Future Expected Soon

SCANA, represented by principal subsidiary South Carolina Electric & Gas Co. (SCE&G), and Santee Cooper in a statement on July 27 said they expect the cost to complete the Summer plant will “materially exceed” both Westinghouse’s estimates for completion and the payments from Toshiba, outlined as $ 2.168 billion over a five-year period. SCANA and Santee Cooper said they expect to decide soon whether they will continue with Summer’s construction, modify the project, or abandon it.…

Analysis Shows U.S. Nuclear Plants Losing $2.9 Billion Annually

Increased use of less-expensive natural gas and renewable sources of energy for power generation is putting financial pressure on U.S. nuclear power plants, according to an analysis of electricity costs from Bloomberg New Energy Finance (BNEF).

Nicholas Steckler, an analyst for BNEF, in a June 14 report said nuclear operators are losing about $ 2.9 billion a year. Steckler said nuclear plants are being paid $ 20/MWh to $ 30/MWh for their electricity, while their generation costs an average of $ 35/MWh.

The report says 34 of 61 U.S. nuclear plants are in the red. Steckler specifically cited merchant nuclear plants owned by FirstEnergy Corp., Entergy Corp., and Exelon.

In a statement, Entergy said it would not comment on individual plants but said “financial challenges due to sustained wholesale power price declines and unfavorable market conditions” are affecting the profitability of its nuclear operations. The company said it is now concentrating on its regulated utility business. Entergy, along with its wholesale commodities division, owns seven U.S.…

Chinese Reactor Is Ahead of Schedule as U.S. Nuclear Projects Flounder

China National Nuclear Corp. (CNNC) completed the dome lift at Fuqing Unit 5—the world’s first power plant being constructed utilizing the HPR 1000 (also known as the Hualong One) reactor design—15 days ahead of schedule on May 25.

The feat was no small accomplishment. The dome weighs about 340 metric tons and has a diameter of 46.8 meters (more than half the length of a U.S. football field). It was said to be the world’s largest and highest dome lift ever undertaken at a nuclear construction site (Figure 1). The dome—composed of 153 prefabricated components divided into five layers—ensures the integrity of the unit’s reactor building.

“That the dome was lifted 15 days in advance proves that CNNC can construct the HPR 1000 which is a national key project in the field of nuclear power,” Wang Shoujun, chairman of CNNC, said in a press release.…
