POWER

POWER marks its 130th year of service to the power generation industry with this issue. Instead of cake for the staff, we decided to celebrate the milestone in a way that will benefit our readers and supporters for many years to come.

The March 2011 Japanese earthquake and tsunami that destroyed a number of Japanese power plants—most notably, four nuclear units—hit quickly. Almost as speedy were calls to take all other nuclear units out of service for safety reviews. What will take much longer is developing a new, sustainable energy plan to fill the generation gap left by a potential total lack of nuclear power.

Large circles represent technical reserves and small (blue) circles represent potential reserves of shale gas, both in trillion cubic feet. Bars on the right represent each region’s existing natural gas–fired generation in 2008 (yellow) and the amount projected for 2035 (blue) in TWh.

Online learning is opening up new opportunities for those unable to attend classes on campuses. Bismarck State College and the University of North Dakota, for example, offer innovative online courses and degree programs to students who want successful careers in the electric power industry.

Massive offshore shale gas reserves exceeding 1,000 trillion cubic feet (tcf) discovered in the UK in April could catapult that country to the top ranks of global producers.

Combined cycle power plants use fuels and other materials that can cause fires or explosions in the combustion turbine, ducting, or heat recovery steam generator. Purging that equipment with ambient air to displace residual combustible gases before starting is a normal safety practice. But when plants are cycled, the disadvantages of purging often outweigh the advantages.

This overview of Japan’s nuclear fleet is a web supplement to the June 2012 feature “Japan Scrambles to Revamp Its Electricity Sector.” For a list of major Japanese generating companies, see Figure 1 in that article.

Denmark’s parliament in late March agreed to a new energy strategy seeking to wean the country off oil and gas. It could result in the Nordic country cutting its greenhouse gas emissions 34% by 2020, compared to 1990 levels, and decreasing energy consumption by more than 12%, compared to 2006.

Most power plants use some form of condenser performance-monitoring protocol. Some of those protocols are deficient because the proper instrumentation is not installed to collect the necessary data. Three case studies illustrate how collecting good condenser performance data enabled plant staff to troubleshoot problems and make good plant performance improvement decisions.

The U.S. Supreme Court is considering whether to hear a case filed by several states and citizen groups against the Federal Energy Regulatory Commission (FERC) that contends that FERC Order 697, issued in 2007 to improve market-based rate regulations, exceeds FERC’s authority under the Federal Power Act (FPA).

Planning reserve margins in California and Texas will be "tight" this summer, and New England generators could face uncertain supplies of liquefied natural gas (LNG), the North American Electric Reliability Corporation’s (NERC’s) newly released 2012 Summer Reliability Assessment finds.

Over the next five years, at least eight advanced large-scale demonstration carbon capture and storage (CCS) projects will enter operation—five in North America and three in Europe, a Bloomberg New Energy Finance analysis shows. Leading the pack is Pennsylvania-based Air Products & Chemical’s CCS demonstration at a refinery in Port Arthur, Texas, a project that could be operational as soon as next year.

The Nuclear Regulatory Commission (NRC) on Tuesday said it renewed the operating license for the 1972-commissioned Pilgrim Nuclear Power Station in Plymouth, Mass., for 20 more years despite objections by outgoing NRC Chair Gregory Jaczko.

A three-year schedule delay and cost overruns of about $2 billion plaguing the Tennessee Valley Authority’s (TVA’s) project to build a second Watts Bar reactor are directly attributable to deficiencies in the “project set-up” and “ineffective management oversight,” the federal corporation’s Office of the Inspector General (OIG) said in a report last week.

Illinois regulators on Tuesday rejected Ameren Illinois’ $625 million plan to deploy smart grid improvements in its service territory, saying the company not only failed to show it could deliver a cost benefit to customers, but that the deployment plan was “vague and incomplete” and bordered on being more a “general statement of intention to install smart meters in some parts of its service territory.”

The Nuclear Regulatory Commission (NRC) should examine the benefits of mandating that nuclear plants in the U.S. add probabilistic risk assessment (PRA) to methods used to evaluate and prepare for natural hazards, the Government Accountability Office (GAO) finds in a new report.

Just weeks after the U.S. Commerce Department slapped a 31% tariff on 61 Chinese crystalline silicon photovoltaic (PV) cell producers and exporters, it imposed preliminary duties of as high as 26% on imports of utility-scale wind towers from China.

Trying to assess the potential for coal-to-gas switching in today’s environment is something of an art form. Suppose for a moment that one were able to devise an economic model that truly replicates real-world generation dispatch for plant operators. A model is only as good as the inputs that go into it, and, let’s face it, future natural gas prices are a critical component.

In late March, the Environmental Protection Agency (EPA) proposed its first-ever carbon pollution standard for new power plants, limiting carbon dioxide emissions from new fossil fuel–fired power plants. However, the technology options for complying wiith the proposed rule remain few and expensive, as recent developments demonstrate.

Coal generation, as a percentage of total power output in the U.S., declined steadily to 39% at the end of 2011 from about 51% in 2002, while generation from natural gas–fired combined cycle plants grew to more than 20% from 10% over the same period, the Federal Energy Regulatory Commission (FERC) said in late April, as it released its annual assessment for U.S. energy markets.

Two Environmental Protection Agency rules are facing legal challenges. The Mercury and Air Toxics Standards is being challenged by half the U.S. states, while a decision in a case concerning the Cross-State Air Pollution Rule could be reached as soon as this summer.

Coal combustion products often can be recycled into a variety of construction and building materials. However, first you must be able to retrieve the wet ash from a holding pond before the ash can be dried and sold.

The already low quality of scientific publication has now reached rock bottom. The Onion recently reported on three scientific studies that put illustrate how far quality scientific inquiry has fallen.

Is natural gas as clean a fuel as we are led to believe? A recent study by a Cornell University professor concludes that leaks of natural gas into the atmosphere may make coal the better choice.

The Obama administration often says that there is room for coal in our future fuels mix. However, the administration’s actions lead me to believe President Obama has something much more profound in mind.

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 this three-part report, we introduced the A-USC boiler. In this segment, we look at the metallurgical advancements required for the A-USC boiler to operate at such high temperatures. The final report will explore the A-USC boiler’s unique design challenges.

Finding in a preliminary determination that crystalline silicon photovoltaic (PV) cells are being sold in the U.S. at below-market prices that harm domestic manufacturers, the Commerce Department slapped a 31% tariff on 61 Chinese PV producers and exporters with slight variations by company. All other Chinese producers and exporters of the cells will be subject to a tariff of nearly 250%. The decision has incited mixed, heated reactions from the solar industry.

Compliance with the Environmental Protection Agency’s (EPA’s) Mercury and Air Toxics Standard (MATS) by April 2015 will require coal generators in the Midwest to install retrofits at a pace and scale that exceeds “historical demonstrated capability,” and it will impose taxing bottlenecks on the nation’s power sector labor, equipment, and supply chain, a new study suggests.

A new report shows that the reserve margin for the Electric Reliability Council of Texas (ERCOT) could plunge to 9.8% as soon as 2014, to 6.9% in 2015, and to a negative margin by 2022—well below the grid operator’s 13.75% target for electric generation capacity that exceeds the forecast peak demand on the grid.

Nuclear Regulatory Commission (NRC) Chair Gregory Jaczko on Monday announced his resignation after more than seven years as a member and three years as head of the federal regulatory body. But Senate Majority Leader Harry Reid (D-Nev.) last week suggested that Jaczko could be re-nominated if a successor is not confirmed by June 20, 2013, when the chairman’s first term ends.
