California’s Cap-and-Trade Program is the only cross-industry, market-based climate change regulatory program in the United States. This program may provide a good investment opportunity for dairy farmers, livestock owners, and others if the program’s Livestock Project protocol for offsets can get off the ground and maintain a viable price for greenhouse gas (GHG) allowances.

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.

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.

Patterns of coal trade have been shifting in recent years as demand surges in Asian countries. Whereas Japan and the European Union (EU) have long been the world’s largest hard coal importers, China and India are now emerging as top importers. This surge has shifted the center of gravity in international coal trade to the […]

In 2009, the North Carolina Asheville Regional Airport Authority (Airport), with partners Progress Energy Carolinas Inc. and Charah Inc., began development of the Westside Development Fill Project (Westside Project), a long-term infrastructure strategy located in the southwest quadrant of the Airport’s property. The project included phased construction of a developable pad for general aviation and commercial use, a new taxiway running parallel to the existing runway, and a major expansion of the existing runway.

Following safety rules is the foundation to eliminating injuries. Commonly, a safety presenter will say that safety rules are “written in blood.” At one time, such dramatic statements were a way to get attention and illustrated the seriousness of following safety rules. Today, more highly educated workers demand less drama and more facts.

This is the fifth in a series of predictive maintenance (PdM) articles that began in the April 2011 “Focus on O&M” in which the essentials of PdM were introduced. In the May and June 2011 issues, we explored specific PdM techniques, such as motor-current signature analysis and oil analysis. In the November 2011 issue, we introduced the value of thermographic analysis and its routine use. This installment focuses on ultrasonic and vibration analysis.

In February 2012, the Nuclear Regulatory Commission approved two combined construction and operating licenses for Southern Nuclear’s Plant Vogtle Units 3 and 4 in Georgia. They were the first licenses ever approved for a U.S. nuclear plant using the one-step licensing process and the first allowing construction in more than three decades. Now the real work begins.

Europe’s continuing drive toward sustainable energy does not rule out a new generation of coal power plants to replace those scheduled to close by 2015.

What do iPads, flat screen TVs, Chevrolet’s plug-in Volt, and Raytheon’s Tomahawk cruise missiles have in common? Each uses one or more of the 17 rare earth elements in their manufacture, and over 95% of those elements come from China.

Lakeland Electric’s C.D. McIntosh, Jr. Power Plant is a microcosm of the entire power generation industry. On a single site is a once-baseload coal-fired plant that is now operating fewer hours plus a peaking gas-fired combined cycle plant that has swung to baseload operation. A complete controls upgrade of the gas-fired plant last year prepared the plant for its expanded role in producing electricity for this 108-year-old public power provider.

While the proposed federal renewable portfolio standards (RPS) continue to be caught in Washington gridlock, a number of states are aggressively enacting programs that promote renewable energy, such as wind and solar power.

Natural gas–fired fleets comprising diverse turbine unit types are operating their units more these days because of the historic low price of natural gas. With increased operating hours, fleet owners are challenged to find the best ways to manage their SCR catalyst systems.

The U.S. uses a combination of direct expenditures, tax breaks, loan guarantees, and research funding to promote various energy goals. We could rely solely on the free market and avoid using federal subsidies, but we do not do that now and appear unlikely to do so in the future.

The operation of solar thermal power plants differs substantially from that of fossil-fired plants, as the sun determines the generation rather than market demand. However, design of the power island to minimize water usage is very similar to that of a fossil plant. This renewable technology requires renewed thinking of its water systems’ design.

India, a country that plans to fuel its current level of gross domestic product growth of between 8% and 9% with massive, mostly coal-fired power capacity additions over the next decade, in March commissioned an 800-MW supercritical unit at the first of India’s government-envisioned ultra-mega power plants (UMPP).

The year 2012 represents a turning point for the smart grid. Many foundational elements have been tested; several have been successfully deployed. Now the serious work of integration and value-generation begins, even though the challenges remain substantial.

For years, tensions have been brewing between Russia, which provides about a quarter of the natural gas consumed in the European Union (EU), and neighboring Ukraine, a country through which 80% of those exports travel via pipeline.

Unpredictable periods of operation are one of the disadvantages of wind and solar technologies. If there were an economic means of storing the energy from the time of production to the time of demand, the value of renewable energy sources would greatly increase. Here are some ideas for how to bridge that gap.

Close on the heels of its recent upgrades of the GT26 and GT24 gas turbines for 50-Hertz and 60-Hertz power markets, Alstom in March launched its next-generation GT13E2 gas turbine, a medium-sized gas turbine of the 200-MW class.

The commercial development of nuclear power began immediately after the Second World War ended and the Manhattan Project secrets were released to the public. As the headline—also the title of a new book—implies, the development path was not always straight or even clearly marked. In this POWER exclusive, the first chapter of Too Dumb to Meter begins a serial presentation of the book.

A new technology promises major advantages for coal-fired power plants, steel mills, and other industries that produce flue gases—and it could quell concerns about the increased use of arable land and food prices related to the production of ethanol.

Magnalight.com announced the addition of the EPL-QP-1X150-100—a quad-pod mounted light tower designed to provide operators in hazardous locations with a powerful lighting solution—to its extensive line of explosion-proof lighting equipment. The portable tower and removable lamp assembly design of this tower provides versatile operating options, and a simple halogen lamp provides effective yet economical illumination. […]

Exploiting the difference in salt concentrations between the freshwater runoff from river mouths at the point where they meet saltwater reservoirs such as seas and oceans to harness power isn’t a new thing.
