Industrial control systems (ICSs) manage global industrial infrastructures, including electric power systems, by measuring, controlling, and providing a view of control processes that once were visible to the operator but now are not. Frequently, ICSs are not viewed as computers that must operate in a secure environment, nor are they often considered susceptible to cybersecurity threats. However, recent cybersecurity failures have proven these assumptions wrong.

The cybersecurity needs of the electric power industry are unique, due to the critical nature of the product and the wide range of technologies that must be considered—from complex, modern industrial control systems to aging infrastructure elements.

The U.S. Environmental Protection Agency has regulated particulate matter as an air pollutant for more than 40 years. Over time, PM regulations and testing methodologies have become more complex, with the focus shifting to smaller particle size fractions and the inclusion of the condensable form of PM. New developments make navigating the permitting and compliance process efficiently more important than ever.

Combining concentrating solar power (CSP) with thermal energy storage shows promise for increasing grid flexibility by providing firm system capacity with a high ramp rate and acceptable part-load operation. When backed by energy storage capability, CSP can supplement photovoltaics by adding generation from solar resources during periods of low solar insolation.

Dr. Daniel Yergin, chairman of IHS Cambridge Energy Research Associates, is a Pulitzer Prize–winning author; leading authority on energy, international politics, and economics; and a recipient of the United States Energy Award for “lifelong achievements in energy and the promotion of international understanding.” He recently spoke with POWER about his latest book—and more.

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.

A model of Switzerland’s energy future to 2050 that abides with the country’s post-Fukushima decision not to build any new nuclear power plants suggests the phase-out could cost nearly $33 billion.

As the book title Too Dumb to Meter: Follies, Fiascoes, Dead Ends, and Duds on the U.S. Road to Atomic Energy implies, nuclear power has traveled a rough road. In this POWER exclusive, we present the second chapter, “Manhattan Transfer,” which covers the open fight for control of the development of nuclear power between the newly created Atomic Energy Commission and the military services, with the politicians playing both sides against each other.

Oxyfuel technology has been retrofitted at a 700-MW coal-fired power plant in Queensland, Australia, and is now capturing carbon dioxide from one of the plant’s six steam boilers.

The new DustBoss from Dust Control Technology DB-M is designed for applications in which a fan-driven mist could generate undesirable turbulence and is well-suited to operating conditions involving very fine dust particles, including slag dust or fly ash. The unit generates an umbrella-shaped cloud of atomized droplets averaging 50 to 200 microns in size and […]

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.

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.
