Southern California Edison (SCE), operator of the San Onofre Nuclear Generating Station near San Clemente, Calif., must understand and address unusual wear on steam generator tubes before it can be allowed to restart the beleaguered two-reactor nuclear plant, the Nuclear Regulatory Commission (NRC) said on Tuesday. California officials are meanwhile preparing contingency plans to prevent power outages this summer that could result from the plant’s indefinite shutdown.

The Nuclear Regulatory Commission (NRC) will decide on Friday whether to award a combined construction and operation license (COL) to SCANA Corp.’s proposed project for two 1,117-MW reactors at the site of the V.C. Summer Nuclear Station near Jenkinsville, S.C. If the SCANA Corp. project receives the NRC’s approval, it will be the second project in nearly 30 years to receive such approval.

By Kennedy Maize Washington, D.C., 28 March 2012 — Just how significant is the Obama administration’s new regulation on carbon dioxide emissions from new coal-fired power plants, announced yesterday? From here, it looks like a fair amount of ado about not very much. In today’s cynical political environment, it’s hard not to see the Environmental […]

A new report released in early March by the North American Electric Reliability Corp. (NERC) found that loss of reactive power was the most likely outcome from a severe solar storm that was centered over North America. Significant losses of reactive power could lead to voltage instability, and, if not identified and managed appropriately, power system voltage collapse could occur, the report concludes.

It has been said that a picture is worth a thousand words. However, photos of the conflagrations that have resulted from ignition of minor lube oil leaks on a typical steam turbine room floor will leave you speechless. Full-scale physical simulations of oil fires by the insurance company FM Global leave no doubt that power plant fire prevention and mitigation is a judicious blend of art and science.

This unconventional technique for removing slag from solid fuel-fired boilers, used for more than two decades, has exploded in popularity. But the risks are very real, and not all blasters are created equal.

Moving into the election season, President Obama has again pointed to the number of green jobs supposedly created by his administration in a recent campaign advertisement, although the claims are not supported by available data. Now, other government authorities are using the same poor data as an excuse to increase spending.

Advanced ultrasupercritical (A-USC) is a term used to designate a coal-fired power plant design with the inlet steam temperature to the turbine at 700C to 760C. In Part I of a three-part report, we introduce the A-USC boiler. Future reports will discuss the metallurgical and boiler design challenges.

What killed global warming as the president’s number one priority?

Freedom, opportunity, prosperity, and a civil society have made America exceptional. But without energy—secure and affordable energy—many of our great accomplishments would not have been possible.

FirstEnergy Corp., AEP, and GenOn have all announced coal-fired plant closures, totaling over 13 GW, caused by the recently finalized Mercury and Air Toxics Standards.

A proposed rule issued in late February by the Environmental Protection Agency (EPA) will not change the greenhouse gas (GHG) permitting thresholds for the Prevention of Significant Deterioration (PSD) and Title V Operating Permit programs. However, it includes revisions to the permitting program that would provide some flexibility in how compliance is achieved with GHG emission caps.

After concluding that the Chinese government provided illegal subsidies to domestic solar panel makers, the U.S. Commerce Department on Tuesday said it would impose countervailing duties on the imports of Chinese crystalline silicon photovoltaic (PV) cells and modules. But the tariffs were smaller than some solar companies had petitioned for, ranging at 2.9% to 4.73%, depending on which company manufactured them.

In a major setback for Southern Co.’s 582-MW integrated gasification combined cycle (IGCC) Kemper power plant that is under construction in Kemper County, Miss., the Mississippi Supreme Court reversed an order by the Mississippi Public Service Commission (MPSC) granting the project a Certificate of Public Convenience and Necessity.

In the past week, Ontario’s Bruce A restarted after 17-year hiatus, with hiccups; Indian state approval restarted work to complete Kudankulam; Vermont Yankee turned 40; and Entergy won a new legal round to keep the contested Vermont reactor operating.

NRG Energy last week filed a notice of intent with the New York Public Service Commission (PSC) to mothball Units 1, 2, 3, and 4 of its 635-MW Dunkirk coal-fired power plant near Buffalo, N.Y., by September this year until market conditions improve.

The Federal Energy Regulatory Commission (FERC) last week conditionally approved an enforcement approach proposed by the North American Electric Reliability Corp. (NERC) that allows industry to self-report “low risk” reliability standard violations. The initiative will “free up resources and attention to address more serious risks to reliability,” FERC said in its decision.

An agreement reached between the Federal Energy Regulatory Commission (FERC) and Constellation Energy Commodities Group will require the company to pay $245 million to settle FERC allegations that the company manipulated power markets run by the New York Independent System Operator (ISO) and ISO New England between September 2007 and December 2008. The penalty is the largest ever imposed by FERC under the expanded enforcement authority assigned to the federal body in 2005.

Cap and trade programs to reduce emissions do not inherently provide incentives to induce the private sector to develop innovative technologies to address climate change, according to a new study from the Lawrence Berkeley National Laboratory in the journal Proceedings of the National Academy of Sciences.

Enough capacity exists in deep saline aquifers in the U.S. to store about a century’s worth of carbon dioxide emissions from the nation’s coal-fired power plants, a new study from researchers at the Massachusetts Institute of Technology (MIT) shows.

By Thomas W. Overton San Diego, 20 March 2012 — A fair amount of ink has been spilled in the commodities market over record natural gas storage inventories in the U.S. As of March 9, they stood at 2,369 Bcf, a whopping 735 Bcf more than this point last year, and well above the previous […]

By Kennedy Maize Washington, D.C., March 20 2012 — The most important economist you probably have never heard of is William Stanley Jevons. Contemplating the convergence of coal, industry, and technology in the middle of the 19th Century, Jevons explained why increasing efficient use of coal meant more, not less, use of the dusky diamonds […]

By Thomas W. Overton, JD San Diego, 16 March 2012 — Yesterday, the NRC announced that it is sending a special team to San Onofre after several steam generator tubes in one of the reactors failed an inspection. This isn’t good, but probably sounds worse than it is. First, full disclosure and some background: I […]

By Kennedy Maize Washington, D.C., 14 March 2012 — Climate science is a wicked mess. That’s not a political statement or a casual description of the difficulties of the man-made global warming knife fight. It’s a technical term some social scientists use to shed light on complex, convoluted, interconnected problems. It also provides a useful […]

A bill introduced by Sen. Lindsey Graham (R-S.C.) on Monday could force the government to provide rebates for $35.8 billion collected in the Nuclear Waste Trust Fund since 1983 to help build and operate the permanent federal nuclear waste repository at Yucca Mountain in Nevada. According to the Nuclear Energy Institute, customers have been paying […]

Dynegy Inc.’s transfer of some coal plant assets to itself from its subsidiary Dynegy Holdings two months before the latter company filed for bankruptcy protection last November represented a “fraudulent transfer,” a court-appointed examiner in the bankruptcy case said in a report released on Friday.

Exelon Corp. and Constellation Energy on Monday completed their long-awaited $7.9 billion merger. The combined company, which retains the Exelon name, has a market cap of $34 billion, a 35-GW generation fleet, and activity in 47 U.S. states and some Canadian provinces. It is now the biggest power utility in the U.S.—until the $26 billion Duke-Progress merger is completed, at least.

A bill passed with a bipartisan vote of 265–154 by the U.S. House last week seeks to fast-track permitting for hydropower installations of 1.5 MW or less in canals and pipelines by minimizing environmental reviews.

The Nuclear Energy Institute (NEI) last week detailed its “FLEX” response strategy, a program that calls for more safety and emergency response equipment at each of the nation’s 104 commercial nuclear reactors. According to the trade industry group, “The initiative commits every U.S. company operating a nuclear energy facility to order or enter into contract for a plant-specific list of emergency equipment by March 31.”

A report released today by the Solar Energy Industries Association (SEIA) claims that though the U.S. solar power sector was hard hit by policy changes and plunging global prices of photovoltaic (PV) panel prices, it installed 1,855 MW of PV capacity last year—more than doubling the previous annual record of 887 MW set in 2010.
